High-chrome vanadium-titanium magnetite blast furnace smelting charging material and blast furnace smelting method

The invention discloses a high-chrome vanadium-titanium magnetite blast furnace smelting charging material. The high-chrome vanadium-titanium magnetite blast furnace smelting charging material comprises, by weight, 75-85% of sintered ore, 13-20% of pellets and 2-5% of common lump ore. The sintered ore is formed by mixing and sintering materials including, by weight, 50-60% of high-chrome vanadium-titanium magnetite, 20-30% of ordinary iron ore and 20% of fuel and fusing agents. The pellets are formed by mixing and roasting materials including, by weight, 97-98% of high-chrome vanadium-titanium magnetite concentrate and 2-3% of bentonite. The common lump ore comprises, by weight, 40-50% of TFe and 15-25% of SiO2 and is free of vanadium and titanium. According to the high-chrome vanadium-titanium magnetite blast furnace smelting charging material, the metallurgical property during smelting is enhanced mainly by improving the high-chrome vanadium-titanium magnetite blast furnace smelting charging material.
