Abstract
A technology for melting structural cryogenic 12Kh18N10T steel from industrial wastes in an induction unit consisting of two induction core-free 1100-kg FS furnaces has been developed. The paper considers the problems of charge preparation, namely, the fraction composition, the oxidation level, the content of harmful impurities, and the method of its charging, to ensure the resistance of a crucible and a decrease in the melting period ad the problems of the order of introducing alloying and slag forming elements. The results of experimental–industrial heats show a decrease in their contents by 3–5% at a decrease in the metal loss by 2–4% and a specific energy consumption of 570–780 kWh/t. Recommendations on a decrease in the meniscus height on the melt surface are given.
