METHOD OF BLAST-FURNACE SMELTING Russian patent published in 2004 - IPC

Abstract RU 2237723 C1

FIELD: ferrous metallurgy; blast-furnace process; making iron in blast furnaces.

SUBSTANCE: blast-furnace charge includes carbon-containing additives-briquettes manufactured from carbon-containing materials and natural or technogenic materials. Briquettes are charged in circular peripheral zone of furnace top bounded by radius of 0.4-0.9 of radius of furnace top. Briquettes contain the following elements and oxides: C:Fe=0.25-0.55; CaO:SiO2=0.3-1.6; MgO:Al2O3=0.25-1.25.

EFFECT: reduced consumption of coke; enhanced utilization of industrial wastes.
