The use of plasma for controlling the temperature of steel during continuous casting
The temperature drop that takes place in steel during casting is one of the main factors that reduces both the product quality and the plant yield. In this research, the CSM has investigated on an industrial scale the possibility of using plasma torches as heat sources to control the steel temperature in the tundish. The main characteristics of this system are: - generation of large quantities of power without polluting the steel, and - flexibility of use in relation to the thermal needs of tundish geometry. Various heating tests were carried out, using a ferrous stainless steel (AISI 430 F) which, of all produced in Aosta, shows the greatest temperature drop. The steel temperature is controlled constantly by means of thermocouples, which maintain a continuous signal for the entire period of casting.
