针对承钢含钛高炉渣黏度大,渣铁分离较差,炉渣中含金属铁2%左右,给高炉渣利用带来困难,使生铁成本升高等问题,研究了渣中铁的存在形式,TiO_2含量对渣中铁聚合的影响,以及铁聚合机理。研究结果表明:随着TiO_2含量的增加,渣样中的铁珠的聚合效果越来越差,铁珠聚沉的位置由渣样的底面和侧面转移到渣样的顶部和侧面,并且渣样与坩埚的界面产生了金红色高熔点物质Ti(C,N)。随着渣中TiO_2含量的增加,炉渣中的铁含量从0.4%持续升高到1%。
In view of the problems such as the high viscosity of the bearing titanium-bearing blast furnace slag, the poor separation of the slag and iron, the slag containing about 2% metallic iron, the difficulty in using the blast furnace slag and the increase of the pig iron cost, the existing forms of iron in the slag, On the slag iron polymerization, as well as iron polymerization mechanism. The results show that with the increase of TiO 2 content, the effect of the iron beads in the slag samples is worse and worse. The location of the iron precipitation is transferred from the bottom and the side of the slag sample to the top and the side of the slag sample. The interface with the crucible produced a gold-red refractory substance Ti (C, N). With the increase of TiO 2 content in slag, the content of iron in slag continuously increases from 0.4% to 1%.
