SIMETAL LiquiRob for EAF

The main demands to be met by modern steel production are high productivity, high production flexibility and a high product quality level.

Robots are common in operation in high productivity, reproducible and flexible industries, for example, in car assembling manufacture. Now, Siemens VAI, as a pioneer in innovating processes, technologies and automation at steel plants, introduces a robot suitable for the harsh operation conditions and rough environment at casters, secondary metallurgical plants, converters and also EAFs.

Our answer to these demands is an extremely fast Siemens VAI robot performing fully automatic temperature and sample measurements cycles including cartridge replacement, so that manual and even manipulator measurement are obsolete.

Your challenge:

Personnel health and safety when working in the vicinity of steel, slag and extremly hot environment is our main concern. The steelplant managers take full responsibilty regarding health and safety of their employees as well as strict compliance with the associated legislation.

A further issue is accuracy and reliability in performing measurement and taking samples during production, having direct influence on the quality of the produced steel and on productivity thanks to faster cycle times and less measurement errors.

Our solution:

With the SIMETAL LiquiRob, Siemens VAI provides a highly flexible robot-aided measuring and sampling solution that gives you the flexibility and reliability needed to ensure uninterrupted, fail-safe and controlled EAF steel production.

The SIMETAL LiquiRob will replace mechanical manipulators benefiting from higher availibility and easy upgrading and learning of new operations. In many cases it will prevent operators from making temperature or celox measurements or taking samples. Thanks to the SIMETAL LiquiRob, work in hazardous areas is largely eliminated.

Additional features

The SIMETAL LiquiRob recognizes defective cartridges and sorts them out before carrying out any measurement, thus avoiding time-consuming measurement errors. Furthermore it is also possible to check the contact rod position, so the availability of the system is guaranteed.

Maximum flexibility

Flexibility in movement

With its 6-axis movement, the SIMETAL LiquiRob may be applied even under extremely tight space conditions. Consequently, very short cycle times can be achieved. Furthermore, the SIMETAL

LiquiRob is a perfect upgrade solution for existing plants.

Flexibility in measuring

Due to its high degree of flexibility, the SIMETAL LiquiRob can be used for handling various kinds of cartridges, without any major modifications.

Low maintenance costs

The SIMETAL LiquiRob is a proven, matured system and is virtually maintenance-free. The maintenance cycles are significantly longer when compared to those of conventional manipulators. To protect it from dust and heat, the robot is covered with a special fabric.

Ease of use

During most of its operating time, the SIMETAL LiquiRob needs no operator interaction because the system is controlled by a state-of-the-art automation system. A Siemens HMI guarantees easy handling and short learning time.
