Аннотация: A brief analysis of the cast iron and steel smelting in induction furnaces of industrial and medium frequency has been carried out. The analysis of the used metal scrap for the smelting of synthetic iron in induction melting furnaces with a padded lining of a lining mixture, based on quartzite, is carried out. The requirements for Показать полностьюtemperature melting modes, which are regulated by this type of melting furnaces developers, are reflected. The advantages and disadvantages of using induction crucible furnaces of industrial and medium frequency are considered. The features of smelting synthetic pig iron in Russia are noted, the main of which are the following: the absence of cast iron scrap, which makes it necessary to use a metal scrap from a single steel scrap, and use temperature melting conditions above 1450 ° C; use a lining based on quartzite, as the cheapest, but sharply reducing its resistance to the operation of the furnace at such melting temperatures (from 300-350 to 200-250 smelts). The actuality of the possibility of steel smelting in induction crucible furnaces of industrial frequency with the use of acid lining, based on the Pervouralsk quartzite, is substantiated. It is explained by the fact that existing foundries are equipped mainly with induction melting furnaces of industrial frequency, and the use of induction melting furnaces of medium frequency requires considerable material costs. © 2020 Trans Tech Publications Ltd, Switzerland.
