Smithy

• It is understood to handle relatively small jobs which can be heated in open fire or hearth (furnace)

• The shop in which the work is carried out is called Smithy shop

• Forging means , production of those parts which must be treated in furnace

Types of furnace used in smithy workshop

Rotary Hearth Type FurnaceThis furnace can be designed and manufactured to a corresponding material’s shape & size. A maximum throughput of 1.5 ton/hr, 5 ton/hr or 8 ton/hr can be achieved through the use of a recuperate and manipulator.

Batch Type FurnaceThis furnace can correspond to variations of materials’ shape, size, throughput, and required heat. Use of a recuperate can enhance furnace operation and energy savings.

Conveyor Furnace A conveyor belt furnace is a furnace uses a conveyor or belt to carry

process parts or material through the primary heating chamber for rapid thermal processing.

Process of Smithy:-• The 100mm and 120mm in

diameter mild steel rod is given.• The rotary hearth furnace is used and is lighted up by the coal and the blower is used for fire , so that it doesn’t get stop.• The fire is blown properly so that the mild steel rod can

be heated uptil it’s forging process.

Furnace

• With the Help of RIVET or RING Tong the piece of mild steel is kept in the furnace till its becomes red hot.

• Then after few time when it reaches to its ,it is taken out, rapidly it is hammered and again kept in the furnace to make it hot from all side.

• Thus, by this process it is made flat.• The forging temperature of mild steel is 1250

to 1300 C.

Red Hot rod

Types of tong

• The rod is made flatten as shown in figure.

• Its is made of 18*65*65mm.

• When we do with hammer it is slightly rough surface we get, So to make it soft we use hammer and Flatters.

Flatter

Flat steel after using flatter

• The side greater than desire length is cut by heating the rod , then the extra rod is cut with the help of chisel and hammer.

• By striking hardly with hammer when the bar is hot, it is cut.

• The right angle on all the corner are made by hammer and keeping it on flat surface.

• The center point is then marked with scale, hammer and chisel.

• Again after heating the rod it is kept on the Anvil and with the help of chisel and hammer the curved is made on the rod.

• After heating the rod , it is made “L” Shaped by hammering.

Anvil

Smithy process of converting Mild steel rod into L shape

Price of converting Mild steel rod to L shape

The cost of steel is 47060 Rs./tonne .At the smithy shop we were given rod of

approximately 0.5 kg.So costing is 23.53 and the coal cost is

4420/short ton.So total cost of smithy shop is 23.53Rs. Of coal

and 44.2 Rs. of coal for burning so approximately 68Rs. Is cost.
