电弧炉熔化分离铁、钛和炼钢的试验研究是综合利用磁铁矿和钛铁矿共生矿试验方案中的一部分。试验方案包括:铁精矿—钠化球团—水浸提钒—直接还原—分离铁、钛。本试验于1980年完成了实验室开发研究,以50kg中频感应炉熔分了22炉,以0.5t电弧炉熔分了42炉。1982年完成了半工业试验,以3t电弧炉熔分了32炉,以1t电弧炉熔分了111炉。试验结果表明,以提钒后的含钛金属化球团为原料,采用本工艺可以获得含TiO_2>50％、酸解率>90％的钛渣和温度在1600℃以上,含C0.20～
Experimental Study on Melting Separation of Iron, Titanium and Steelmaking in Electric Arc Furnace is a part of the comprehensive utilization of the test scheme for the symbiotic mine of magnetite and ilmenite. Test programs include: iron concentrate - sodium pellets - water leaching vanadium - direct reduction - separation of iron, titanium. The experiment was completed in 1980, the development of laboratory research to 50kg IF induction furnace melting furnace 22, 0.5t EAF 42 furnace melting. The semi-industrial test was completed in 1982, 32 furnaces were melted in a 3t electric arc furnace and 111 furnaces were melted in a 1t electric arc furnace. The test results show that the titania slag containing more than 50% TiO 2 and the acid hydrolysis rate> 90% can be obtained by using the titanium-containing metallized pellets after the vanadium extraction, and the titanium slag with the temperature over 1600 ° C and containing C0.20 ~
