METHOD FOR PRODUCTION OF SEMIFINISHED PRODUCT FOR METALLURGICAL CONVERSION Russian patent published in 1995 - IPC

Abstract RU 2049120 C1

FIELD: ferrous metallurgy. SUBSTANCE: to produce semifinished product of stable composition, charging boxes of casing machine is loaded with solid materials of different fractions up to filling working volume of charging boxes. In so doing, part of capacity of charging box not filled with solid additives (layer porosity) is maintained within 20-60% of charging box capacity. Part of charging box capacity not filled with solid materials (layer porosity) is regulated by loading materials with fractions of 10-25 mm and fines from -10 to +2 in ratio of 1:(0.5-1.0), respectively. EFFECT: higher efficiency. 2 cl, 1 tbl
