摘要：Induction crucible furnaces with industrial frequency (IChT) have been used since the 50s of the last century. The performance of the furnaces guarantees temperature that is lower than 1450°C for constructors and developers. That is why the lining of these furnaces is made of quartzite, which gives its high resistance (300-350 smelts) for melting alloys at this temperature. However, the developers have provided a power reserve that allows raising the temperature to 1550°C for performing such technological melting operations as the carbonization process with steel scrap, alloying while the smelting of special cast iron, the use of a large amount of light scrap and recovery. Market conditions began to dictate their requirements to the casting manufacturers (the demand for castings from cast iron decreased, and steel increased) and this especially affected the foundries that were equipped with the IChT furnaces only. For this reason, there was a need to develop a technology that allows the steel smelting in an IChT furnace.
