METHOD FOR PRODUCTION OF COMPLEX MODIFIER IN CORELESS INDUCTION FURNACE WITH QUARTZITE LINING

摘要

FIELD: ferrous metallurgy. SUBSTANCE: method for production of complex modifier in coreless induction furnace with quartzite lining includes preparation of melting furnace, charging of ferrosilicon and silicocalcium, melting and removal of slag, pouring into weigh ladle, pouring into reactor ladle onto preliminarily introduced granulated magnesium, and teeming into ingot molds. In so doing, in preparation of melting furnace after complete pouring of sintering metal, aluminium mixture is melted and fully poured, and sintering of the formed layer of oxides by melting of ferrosilicon in melting furnace. Preliminarily heated silicocalcium is introduced in the course of modifier melting prior to poring into weigh ladle into deoxidized melt with active metals and high-melting oxides. EFFECT: higher efficiency.
