foundry

The smelter consists of eight induction furnaces with capacities of 3 to 30 tons, so that unit weights of up to 130 tons can be manufactured. The five large ovens were installed in series on a common oven stage. They are operated via a central, fully electronic control station and are constantly monitored. The alloys and genera to be adjusted are calculated using modern computer-aided systems. The reference alloy is transmitted to the furnaces as a target value.

The casting process takes place in casting pits for statically cast rolls, in centrifugal casting systems for spun rolls and pipes, and in casting boxes for cast parts.

The foundry is also responsible for annealing the workpieces in order to reduce material tensions and carry out thermal material treatments. Depending on the process, the foundry works in three shifts.
