1. General

Touch screen

The function of the Touch Screen is based on the active light matrix principle in the

infrared range. The optical elements of the light matrix are located behind the IR

transparent plastic frame in the front of the device. They are located in such a way that

their radiation extends slightly out of the front plate. Each emitter is assigned a receiver

that is located on the other side. A touch on the screen is detected by the simultaneous

inter-ruption of one or several channels in the X or Y axis.

Repeated touches and touches that cover an area greater than 20 mm x 20 mm are not

evaluated by the touch controller. Continuously interrupted channels caused by severecontamination and dirt or by the failure of an optical element are detected by the touch

controller and are no longer included in the evaluation.

Power up function test

The PCS smart runs through a function test of the Touch Screen with every start-up. All

the IR channels are evaluated and their signal levels compared with those of the initial

values. The initial values are determined before the device is delivered and stored in aretentive memory.

If one or several channel signals are below a minimum relative to the initial level, this will

be indicated on the screen with an error message and the DEF/DIRTY LED will be lit.

A reduced signal level of this kind is normally due to severe contamination of the IR

transparent plastic frame which consequently has to be cleaned. The Touch Screen

however remains fully functional.

Only an increase in the contamination of the screen will lead to the continuous

interruptions of one or several IR channels. IR channels that are continuously interrupted

will be detected by the touch controller and are no longer included in the evaluation. In

extreme cases this may mean that individual zones cannot be activated by touch.

1. General

ATTENTION

Do not touch the screen while the system is being started up and wait until your application

has started.

The Touch Screen carries out a function test during the start-up in which the signal levels

of the IR channels are measured.

Cleaning and maintenance

For operation ensure that the signal levels of the channels are not so severely reduced or

interrupted due to excessive contamination through dirt.

Clean the inside of the plastic frame of the device regularly with a damp soft cloth. Ensure

that the surface is not scratched or scoured, especially when removing hard deposits and

abrasive dusts.

Do not expose the front of the device to solvents which may corrode and loosen the plasticframe (frame material: polymethylmethacrylate, PMMA).

Screen saver

If no key on the Touch Panel is actuated for more than 1 hour, the background lighting will

be reduced to an intensity of 40 %. (This increases the life time of the Touch Panel).

In order to switch the background lighting to 100 % again just touch the screen of

the Touch Panel at any position whatever.

The switching over of the background lighting does not influence the functions of the

Touch Panel.

Input of the minimum time which the torch needs to heat up the strand edge.S = 2 sec.M =

Percentage of preselected cutting speedExample: The preselected cutting speed is 300 mm/min., the initial cuttingspeed is 30 %.Therefore an initial cutting speed of 90 mm/min. results.S = 30 %M =

The initial cutting distance is the distance which the torch travels with reducedcutting speed in order to guarantee a safe initial cutting.S = 30 mmM =

The speed change over from initial cutting speed to cutting speed is done viaa ramp. The ramp time determines the time which the torch uses foraccelerating from initial cutting speed to cutting speed.S = 7 sec.M =

Percentage of preselected cutting speed

Example: The preselected cutting speed is 300 mm/min., the out cutting speedis 70 %.Therefore an out cutting speed of 210 mm/min. results.S = 70 %M =

This value determines the position before the theoretical cutting end, wherethe torch is switched over from the preset cutting speed to the reduced outcutting speed.S = 40 mmM =

Input of the cutting kerf width.

S = 8 mmM =

This is the distance between the two torches, if they are such close together,as it is mechanically possible and if the proximity switch “Torch Meet“ isactuated.S = 110 mmM =

Example: the preselected “Head crop cut stop position“ is determined with 100mm, i.e. the cut will be stopped 100 mm before the slab is cut through.S = 100 mmM =

The input of this value determines the distance when the transport roller tablehas to start, before the theoretical cutting end is reached.S = 10 mmM =

Example: the preselected “Tail cut stop position“ is determined with 200 mm,

i.e. the cut will be stopped 200 mm before the slab is cut through.S = 200 mmM =

This is the safety addition to the theoretical cutting end, which is calculated bythe PLC.S = 10 mmM =

1.5) DESCRIPTION OF CONTROL DEVICES

1.5.1) Proximity switch: MACHINE BACKWARD OFF (S 282)

This switch limits the return travel of the machine in all operation modes. When

it is actuated, it gives the signal “Machine home position”. Furthermore, it is

used for the synchronization of the encoder "Machine position".

1.5.2) Proximity switch: MACHINE BACKWARD SLOW (S 284)

The travel speed is switched over from "fast" to "slow" shortly before reaching

the rear end position by means of this proximity switch. This is effected in all

operation modes.

1.5.3) Proximity switch: MACHINE FORWARD OFF (S 286)

This switch limits the forward travel of the machine in all operation modes. If

the machine reaches this position while sitting on slab, the machine lifts up to

its upper end position in all modes.

Additionally, in semi-automatic and in automatic mode a cutting cycle will be

interrupted and the machine returns to home position.

1.5.4) Thermo switch: MACHINE DRIVE 1 (S 93)

This thermo switch supervises the temperature of machine drive 1 and will be

activated at approx. 150o C. At the same time an alarm on the Operator Panel

display will be generated. The drive itself will not be stopped.

1.5.5) Thermo switch: MACHINE DRIVE 2 (S 95)

This thermo switch supervises the temperature of machine drive 2 and will be

1.5.6) Incremental encoder: MACHINE POSITION (B 433)

Technical data:

Type: Hengstler RI 58 TD / 0250 ED.37KX

Supply voltage: 10 - 30 V

No. of steps: 250 steps/rev.

Channels: A+B channels, shifted by 90°

Circumference of measuring wheel: 500 mm

The evaluation of the encoder is effected by means of a counter module in the

PLC.

This counter is called "Machine Tracking".

The counter module counts the raising and the falling edges of the A + B

channels.

This means, the counter counts 1000 pulses per revolution of the measuring

wheel. Based on the circumference of 500 mm the following results: 1 pulse =

0,5 mm

The synchronization of the counter module will be made by a signal of the

proximity switch “MACHINE BACKWARD OFF“(Machine home position).

The counter module in the PLC calculates the actual machine position referred

to the home position. The shifted pulse channels enable increasing ordecreasing of the calculated position according to the direction of actual

machine movement.

The counter is also used for the determination of piece lengths when the

measuring roller is selected as length measuring system.

This is described in chapter "LENGTH MEASURING".

Furthermore, the counter is used for the following functions:

- to determine roller position

-

to determine the machine position for speed change from fast to slow inforward direction

- to move the shifting table

2.5.1) Proximity switch: MACHINE LIFTING OFF (S 292)

This proximity switch limits the lifting drive moving direction “up” in all operation

modes.

2.5.2) Proximity switch: MACHINE PRELOWERING (S 294)

This switch is used for: 1. Prelowering procedure for any cut

2. Lowering procedure for tail cut.

1. Prelowering procedure

The signal of the switch activates a timer. The length of the timer is depending

on the strand thickness (in Level 1 mode the strand thickness is preselected by

the operator, in Level 2 mode the strand thickness from the higher level

computer is used).

The timer stops the drive when the skid is 5 - 10 mm above the slab.

2. Lowering procedure for tail cut

During tail cuts there is usually no strand underneath the skid.

Therefore the machine down movement must be stopped as described under

item 1. "Prelowering procedure".

In tail cut mode the skid is only travelled until the the prelowering position, i.e.

always over slab level.

General:

With the signal "Lowering" another fixed timer (independent on the format) is

started for approx. 3 seconds. That means the drive is started for approx. 3

seconds, the skid travels from prelowering position (approx. 5-10 mm above

the slab) into lowering position.After the timer run-down the machine sits on the slab.

7. TORCH TRACKING

7.6) CONTROL

7.6.1) GENERAL

The torch tracking system is used for the following :

- to optimize the cutting cycle time

- to guarantee a safe initial cutting and cutting out

- to send output signals, such as roller table start or cutting end, to other

PLCs at the right time

Torch tracking is necessary for all automatic cutting cycles.

Mainly a cutting cycle consists of the following steps :

1. Positioning of the torches at the strand edge

2. Switching on of the torch heating flame

3. Switching on of the torch cutting flame

4. Initial cutting of the strand with slow speed (initial cutting speed)

5. Acceleration via a ramp to the preselected cutting speed

6. Cutting with preselected cutting speed

7. Cutting out with reduced cutting speed

8. Transmission of the signal "Roller table start" to the PLC

9. End of cutting process, cutting flame off, heating flame off

10. Backward travel of torches and machine into home positions

7.6) CONTROL

7.6.2) PARAMETER

The following parameter are set in mm via the Operator Panel (screen Cutting

parameter ) installed in the control desk and are also indicated there.

- For initial cutting:

1. "INITIAL CUTTING DISTANCE"

To guarantee a safe initial cutting the torch is travelled approx. 40 - 60

mm (initial cutting distance) with reduced cutting speed (approx. 30 % of

the adjusted cutting speed).

- For cutting out :

2. Position "TORCH MEET"

This is the distance between the two torches, if they are as close together

as it is mechanically possible and if the proximity switch "Torch 1+2

Forward Off" is actuated. (Approx. 130 mm)

3. Position "CUTTING END"

This is a safety addition to the theoretical cutting end, which will be

calculated by the PLC. (Approx. 30 mm)

4. Position "ROLLER TABLE START"

The input of this value determines the position where the conveying roller

table has to start, before the cutting end is reached.

(Approx. 10 mm)

5. Position "CUTTING OUT"

This value determines the position before the theoretical cutting end is

reached, where the torch speed is switched over from the preselected

cutting speed into the reduced cutting out speed.(Approx. 30 mm)

7.6.2) PARAMETER

6. Position "STOP during HEAD CROP CUT and TAIL CUT"

The cut will be interrupted if a head or a tail cut is preselected. The

corresponding torch remains in this position until the cutting line is above

the crop carriage (not for tail cut).

(Approx. 90 mm).In this moment the cut will be continued, so that the head piece can fall

down into the crop carriage.

Please refer to the FUNCTIONAL PROCESS , chapter HEAD CROP CUT

and chapter TAIL CUT.

Special features:

In the steps 3 - 6 the values to be entered are referred to the theoretical cutting

end, e.g.:

- The torch distance to the cutting end is the sum of the theoretical cutting

end + of the parameter "Cutting end".

- The torch distance to the position "Cutting out" is theoretical cutting end -

position "Cutting out".

7.6.3) CALCULATIONS IN THE CUTTING CYCLE

In each automatic or semi-automatic cycle the PLC calculates the positions of

the parameters described under item 7.6.2 and which have been entered via

the Operator Panel.

These position are calculated twice.

1. When the cutting flame is switched on after heating.

The PLC calculates the positions for both torches.

2. When there is a torch meet before reaching the a.m. positions

(normal cycle with two torches).

During preheating the torch position can be manually corrected.

When switching over from heating to cutting two other parameters are used in

order to calculate the cutting distance:

- Slab width

- Distance slab edge to the torches

In this case the calculation formula is as follows:

THEORETICAL CUTTING END =

DISTANCE SLAB EDGE TO TORCH 1 (2) + SLAB WIDTH

7. TORCH TRACKING

7.6) CONTROL


By means of the theoretical cutting end the PLC can calculate all other important

positions in the cutting cycle.

EXAMPLE : - Distance slab edge to the torch heating position: 15 mm

- Slab width 2000 mm

- Cutting end 10 mm

- Torch meet 120 mm

Then the PLC calculates the position for the theoretical cutting end as follows:

EXAMPLE: - Edges detected

- Torch 1 position = 355 mm

- Torch 2 position = 355 mm

At the moment when the cutting flame is switched on the PLC calculates the theoretical

cutting end positions as follows:

For torch 1 :

Theoretical cut end pos = Actual pos. + Dist. torch 1 to slab edge + Slab width

2370 = 355 + 15 + 2000

For torch 2 :

Theoretical cut end pos = Actual pos. + Dist. torch 1 to slab edge + Slab width

2370 = 300 + 15 + 2000

With these calculations both torches are working like in "Only 1 torch" mode.

The advantage is: If one torch fails during cutting it can be deselected (on the

Preselection screen of the Operator Panel).

The deselected torch then travels back to home position and the other torch can fullfil thecut without any further operator action.

7. TORCH TRACKING

7.6) CONTROL


When the torches meet during cutting a new calculation for torch 1 will be made.

At torch meet torch 2 finishes the cut and travels back to home position.

For torch 1 the calculation of the theoretical cutting end will be made as follows:

EXAMPLE: - Torch Meet- Torch 1 position : 1310 mm

- Torch 2 position : not relevant for the calculation

Theoretical cut end pos = Actual position T1 + "Torch meet"

1430 = 1310 + 120

Based on this value the calculations for the residual cutting cycle will be made.

EXAMPLE: - Parameter Roller table start = 10 mm

- Parameter Cutting end = 10 mm

Roller table start = Theoretical cut end pos - Parameter Roller table start

1420 = 1430 - 10

Cutting end = Theoretical cut end pos + Parameter Cutting end

1440 = 1430 + 10

System 1 : BALL / CHAIN SYSTEM

The mechanical ball/chain edge detectors, which are installed on each torch, are in use.

System 2 : SLAB WIDTH SYSTEM

Based on the slab width the TCM PLC will calculate the theoretical edge position of the

strand.

There are 2 possibilities to insert the slab width:

- Via the Operator Panel, screen Preselection

- Via interface from the Strand PLC, when Level 1/2 is selected.

B143 (B146) = Ball/chain edge detector

- The power supply for the amplifier relay B141 will be switched on by the contactor

K247, when the torch starts travelling to the slab.

- During travelling the ball/chain edge detector B143 hits the slab. This is detected by

the amplifier relay (measuring circuit is Y2-Y1).

- With the signal of B141 the torch will be stopped and K247 will be switched off.

A = A1 + A2

TE1 = (A - W) / 2 Torch 1 edge position

TE2 = (A - W) / 2 Torch 2 edge position

The edge is calculated by the actual slab width as shown above.

The torch travels to this calculated edge position. After stopping at the edge, the heating

flame is ignited and the operator can now see whether the calculated edge is equal to the

actual edge. If a correction is necessary, it must be done by the touch keys "Torchforward - backward".

The correction value is stored with cutting start. For the next cut the torches travel to the

calculated slab edge under consideration of the correction value.

9. MEASURING ROLLER

9.6) MEDIA DIAGRAM FOR MEASURING ROLLER

9.7) CONTROL

The measuring roller is a part of the length measuring device. When the strand head

reaches the measuring roller, the PLC receives a signal from the caster tracking system

‘’Measuring roller up”. With this signal the solenoid valve will be switched on (solenoid

valve opened currentless). Thereby the cylinder pressure is neutralized and the

measuring roller by the counter-weight travels upwards to the strand.

The measuring roller will be pressed against the lower side of the strand. After this the

built-in encoder continuously generates impulses as long as the measuring roller is

pressed against the slab. The counter card counts the impulses and the PLC is able tocalculate the measured length.

After the strand end passes the measuring roller, it is pressed down to home position by

the cylinder.

10. LENGTH MEASURING

The measuring roller and the machine position encoder are used for measuring of piece

lengths.

The measured piece length is indicated on the Operator Panel and is determined as

follows:

-When the strand head is 300 mm behind the measuring wheel center line the roller ispressed against the strand by means of a signal from caster tracking system.

- The strand movement causes the turning of the measuring wheel.

- The machine position is detected by the machine position encoder.

- The impulses generated thereby are counted by the counter modules in the PLC. The

PLC program calculates the actual piece length from the impulses.

- This calculated piece length is compared with the preset value ”cut length“.

- When the strand reaches a length which is approx. 0,5 m less than the preset length,

the machine is prelowered. The length, where prelowering is initiated, is stored as

parameter in the Operator Panel and can be changed, if necessary.

- When the actual piece length and the preset length are equal, the machine is lowered

on the strand.

NOTE:

The measured piece length is used to trigger prelowering and lowering but only when the

machine is operated in AUTOMATIC mode.

12. CUTTING CYCLES

12.1) GENERAL

The following description describes the steps which are executed at each cut.

These steps also apply for special cuts (head crop cut and tail crop cut).

Therefore in the descriptions of special cuts only the differences to normal cut

are detailed.

It is assumed that full automatic operation of the machine is desired. Therefore

the machine should be controlled from the Control Desk. In this case the

machine PLC will receive the slab length setpoints and the kind of cut via

Ethernet interface or via the Operator Panel by using program 1 or program 2

and the machine will operate fully automatic.

- If Automatic is selected, the machine will execute the cut automatically

according to the preset slab length.

- If Semi-Automatic is selected, the machine must be prelowered and

lowered by the operator, because the slab length setpoints are not

evaluated in this operation mode.

- If Manual is selected, the whole cutting cycle must be executed manually

by using the touch keys on the Graphic Panel.

The machine is equipped with a pair of main torches.

Special cuts, such as head and tail cuts, are usually made as described with 2

torches (one pair), but it is also possible to make these cuts with 1 torch only.

12. CUTTING CYCLES

12.2) NORMAL CUT

12.2.1) With two torches (1 pair)

Machine prelowering:

- If the machine is operated in Automatic operation mode, prelowering is

initiated automatically. This is described in chapter LENGTH MEASURING .

If the machine is operated in semi-automatic operation mode, prelowering

is initiated by pressing the touch key “Prelowering” on the Operator Panel.

- With prelowering position the torches travel fast forward to the edge

position.

- On the edge the heating flames turn on.

Machine lowering:

- If the machine is operated in Automatic operation mode, lowering is

initiated automatically. This is described in the chapter LENGTH

MEASURING.

If the machine is operated in semi-automatic operation mode, lowering is

initiated by pressing the touch key “Lowering” on the Operator Panel.

- The cutting flames turn on.

- The torches start to move forward with initial cutting speed. This speed is

approx. 30 % of the normal cutting speed. The torches travel approx. 50mm with initial cutting speed. This is the initial cutting distance. Such a

procedure is necessary to cut the slab edge through.

- After passing the initial cutting distance the torches accelerate to normal

cutting speed.

12. CUTTING CYCLES

12.2) NORMAL CUT


- Both torches cut with normal cutting speed until “torch meet“.

- After “torch meet“ the heating and the cutting flame of torch 2 are turned off

and torch 2 travels with fast speed back to home position or to edge

position. Torch 1 proceeds to cut with normal cutting speed.

- Torch 1 cuts with normal cutting speed for approx. 70 mm.

- Then the cutting speed is decreased to approx. 70 % of the normal cutting

speed. This is cut out speed. With this decreased speed torch 1 cuts

approx. 50 mm.

- Torch 1 returns to home position. At the same time the heating and the

cutting flame turn off.

- The machine lifts up and travels to home position. Depending on the preset

cut length for the next slab there are two possibilities:

1. The new preset cut length is shorter than the machine distance to home

position. The machine will stop to move when receiving the signal

“Prelowering” and a new cutting cycle will be started when receiving the

signal “Lowering”.

2. The new preset cut length is longer than the machine distance to home

position. The machine reaches home position and will wait there for the

signals “Prelowering” and “Lowering”.

12. CUTTING CYCLES

12.2) NORMAL CUT

12.2.2) With one torch

If one torch is out of order a cutting cycle can be executed with one torch only.

The cut with one torch must be selected by the operator. He must select torch

1 or torch 2. It must be considered that a cutting cycle executed with only one

torch takes a longer time than a cycle with both torches. Special cuts (head

crop cut and tail crop cut) can also be executed in this manner.

For that the machine must know the width of the slab. (Via Ethernet interface

or by operator input via the Operator Panel).

- Prelowering, lowering, edge detection and initial cutting are executed in the

same manner as cutting with two torches.

- When the torch comes approx. 50 mm close to the opposite edge of the slab

(this position is calculated by the torch encoder) cutting will be preceded with

cut out speed.

- The movement of the shifting table and roller start are controlled in the same

manner as cutting with two torches.

12. CUTTING CYCLES

12.3) HEAD CROP CUT


- The machine is in home position.

The hot strand head approaches the measuring roller.

- When the hot strand head is above the center line of the measuring roller,

the GeGa PLC receives the signal “Measuring roller up” from the strand

PLC. With this signal the measuring roller is pressed against the strand.

- After a short time the strand PLC sends a second signal "Start measuring".

With this signal the measuring roller starts measuring.

- 500 mm before reaching the preset crop length the torch cutting machine

will prelower. The brakes of both machine drives remain closed.

- Both torches are travelled to the strand edge. When reaching the strandedge the heating flames of both torches are switched on.

- When reaching the preset crop length the machine will lower and the

magnetic brakes of both travelling drives are opened, the machine is now

dragged by the strand (synchronous travel).

The cutting oxygen at both torches is switched on and both torch drives are

started with initial cutting speed.

- Cutting the strand with initial cutting speed.

- Cutting the strand with cutting speed.

- Reaching the proximity switch “Torch meet”. Torch drive 2 is stopped,

cutting oxygen and heating gas of torch 2 are switched off. Torch 2 travels

back to home position or to edge position. Torch 1 continues cutting with

cutting speed.

12. CUTTING CYCLES

12.3) HEAD CROP CUT


- Torch 2 reaches the home position.

- Torch 1 reaches the stopping position for head crop cutting. The cut is

stopped, that means cutting oxygen is switched off and the torch drive is

stopped.

- The machine is still dragged by the strand.

- When the machines reaches the "head cut restart" position the cutting

interruption for torch 1 is deactivated, that means cutting oxygen at torch 1

is switched on again and the torch drive speed is increased to cut out

speed via a ramp.

- Torch 1 reaches the position cutting end. Torch drive 1 is stopped, heating

and cutting flame are switched off. The head crop is cut through.

- The machine is travelled into the upper end position. Torch 1 is travelled

into home position or to edge position. The machine is travelled backward

to home position with fast speed (24 m/min.). The following strand is

pushing the head piece in front of it.

- Before the machine reaches its home position it receives the signal

“Prelowering” from the length measuring. The machine drive is stopped.The torch cutting machine will prelower. The brakes of both machine drives

remain closed. The two torches are travelled to the strand edge. When

reaching the strand edge the heating flames of the two torches are

switched on (normal cut).

12.4) TAIL CROP CUT

12.4.1) General

The tail crop cut is a partial cut only.

A complete cut is not possible, because the tail piece would fall down into the

sinter channel underneath the shifting table.

Cutting above the crop car is not possible because of the mechanical design.

The handling of the last slab with the tail piece at the end requires special

sequences of the torch cutting machine and of the roller table in this area.

The sequences are described in the chapter FUNCTIONAL PROCESS .

The cutting cycle itself is shown on the following pages.

SIMULATION PROGRAM

The software contains a simulation program for testing the torch cutting machine.For starting the simulation the following steps have to initiated :

1. The operator selects simulation mode on the TCM touch panel. This is only allowed if

the Strand PLC reports the “Simulation”.

The simulation mode automatically resets if the Strand PLC resets the simulation flag.

2. The measuring roller is lifted with the signal “Measuring roller up“ from the strand

tracking system.

3. With the signal “Measuring start“ the strand length is calculated according to the

casting speed which is transferred from the strand tracking system.

4. According to the cutting length setpoints (Level 2 or local) the machines are pre-

lowered and lowered. In computer mode the strand width, which is received in the

cutting setpoint, is used, otherwise a fixed value (which is stored on the TCM PLC) is

used.

5. With the signal “Lowering“ generated from the length measuring (preset cutting length

is reached) the machine is travelled according to the casting speed. In order to

guarantee a travelling of the torch cutting machine with casting speed, the casting

speed in simulation mode must be higher than 1,2 m/min.

6. The further procedure corresponds to the functional process on the following pages

and depends on the cutting kind selection (head crop cut, normal cut). All signals of the

simulated “air cuts“ are transferred to Level 1 according to the Interface description.

DBW 52 INT LEVEL 2 WATCHDOG

Watchdog monitoring that the Level 2 Computer is working properly and

valid set-points can be expected from the Level 2.

The watchdog is implemented as a counter running from 0 1 9999

1 9999 (initial value = 0). The counter value is monitored by means

of a time out (30 [sec]).

VALID: If the counter changes within the time out period and the

value is >0.

INVALID: After time out in case of no update.

Immediately if the counter value is <=0. In this case it is not

required to wait for a timeout.

All slab lengths which are preset by Level 2 are processed from the TCM

in Level 2 mode. The length is the net slab length and does not include

any cut loss.

In Level 2 mode the TCM PLC will not check for minimum or maximum

piece length, crop length or tail length.

DBD 84 REAL SETP – PRODUCT WIDTH (WARM)

Dimension: m

The slab width at the cutting position from the L2 strand tracking. The

information is only used as backup if the edge detection on the cutting

machine does not work.
