METHOD FOR WASHING OF BLAST FURNACE HEARTH Russian patent published in 2004 - IPC

Abstract RU 2238329 C1

FIELD: ferrous metallurgy, in particular, melting of cast iron in blast furnaces.

SUBSTANCE: method involves using washing briquettes; charging washing briquettes into peripheral zone of furnace mouth, said zone being defined by radii 0.85-0.5 of radius of furnace mouth. Briquette contains following elements and oxides: C:Fe=0.05-0.15; Mn:Fe=0.03-0.2; CaO:SiO2=0.6-1.2; MgO:Al2O3=0.2-0.6.

EFFECT: increased efficiency of blast furnace and reduced consumption of coke.
