METHOD OF BLAST-FURNACE SMELTING Russian patent published in 2001 - IPC

Abstract RU 2176271 C1

FIELD: ferrous metallurgy; applicable in iron melting in blast furnaces. SUBSTANCE: method includes charging by portions through furnace top of iron-bearing materials, fluxes, coke and bituminous coal, which weight is governed by conditions of coal wedging to periphery or axial zones of furnace. Coal-coke weight ratio is maintained within the range calculated by definite relationship. EFFECT: increased furnace productivity by 20-25%, provision of normal gas dynamics of process with reduced specific consumption of coke. 1 tbl, 1 ex
