摘　　要：针对大型高炉在配用钒钛精矿冶炼过程中存在泡沫渣、粘渣、铁损等问题,开展了钒钛精矿配用比例为0%、10%、20%的烧结试验,确定10%钒钛精矿制作氧化球团。在2500 m^(3)试验高炉上开展试验,优化高炉的装料制度、造渣制度、热制度。结果表明:在燃料比消耗、煤气利用、[Si]含量等比国内2500 m^(3)高炉分别低6.68 kg/t、0.04%、0.06%,实现了低钒钛矿强化冶炼。Sintering tests were conducted using vanadium titanium concentrate in proportions of 0%,10%,and 20%on a 2500 m^(3)experimental blast furnace.These tests were carried out to address issues such as foaming slag,bonded slag,and iron loss that are encountered in the vanadium titanium smelting process of large-scale blast furnaces.The vanadium titanium concentrate,with10%proportion is used to make oxidizing pellets.The charging system,slagging regime,and thermal regime of the blast furnace were constantly optimized.Test results indicate that the specific fuel consumption,gas utilization,and[Si]content of the experimental furnace are 6.68 kg/t,0.04%,and 0.06%lower respectively than those of the domestic 2500 m^(3)blast furnace.The enhanced smelting of low-vanadium-titanium ore has been realized.
