METHOD OF WASH OF BLAST-FURNACE HEARTH Russian patent published in 1998 - IPC

Abstract RU 2112044 C1

FIELD: ferrous metallurgy, particular production of vanadium iron in blast furnaces with use of titanic-magnetic iron ore. SUBSTANCE: wash materials are loaded into central part of furnace top. Vanadium-containing materials are used in form of fluxed materials with content of V₂O₅ of over 1% and basicity exceeding the basicity of furnace charge materials. In so doing, hearth cinder is loaded in 15-20 feeds after loading of fluxed vanadium-containing material. Wash materials are loaded in ratio ensuring equality of wash material basicity with basicity of iron ore charge materials. EFFECT: higher efficiency. 2 cl, 1 tbl
