对冶炼钒钛磁铁矿的0.8m～3高炉的解剖结果进行了研究,认为试验结果是有代表性的。炉内还原过程显示了含钛铁矿物还原的特点。炉内形成特殊的软熔饼状结构是由钒钛烧结矿特有的高熔点渣相所引起的。Ti（C,N）在炉腹和风口区大量生成使炉内的渣铁流动性变坏。Ti（C,N）在渣相中被SiO_2和TiO_2氧化生成黑钛石。用生铁的钛含量判断炉况较用硅含量判断更灵敏。
The anatomical results of the 0.8m ~ 3 blast furnace of smelting vanadium titanomagnetite were studied, and the results are representative. The process of reduction in the furnace shows the reduction of ilmenite containing minerals. The formation of a special furnace-shaped refractory cake structure is vanadium-titanium sinter unique high-melting slag phase caused. Ti (C, N) generated in the bosh and tuyere area to a large extent so that the iron slag fluidity deterioration. Ti (C, N) is oxidized by SiO 2 and TiO 2 into black titanium in the slag phase. The titanium content of pig iron to determine the furnace conditions more sensitive than the use of silicon content.
