采用予氧化钛铁矿,薄料层,连续加料,开弧冶炼钛渣的方法,得到了较好的结果。钛渣、半钢平均含S分别小于0.07％和0.15％。与传统的内配碳团球、埋弧法冶炼钛渣比较,产能提高了2.6倍,电耗降低了20％。基本消除了钛渣冶炼过程中常出现的塌料、喷渣,电流不稳、炉料结壳等不正常状况。为采用封闭炉冶炼钛渣创造了条件。采用渣、铁分别排放的方法,使渣、铁分离好,有利于下一步对半钢的处理。
Adopting the method of pre-treating the titanium oxide with the ilmenite, the thin material layer, the continuous feeding and the open arc smelting titanium slag, good results are obtained. Titanium slag, semi-average steel S containing less than 0.07% and 0.15%. With the traditional carbon ball with the submerged arc method smelting titanium slag compared to 2.6 times increase in production capacity, power consumption decreased by 20%. Titanium slag smelting process basically eliminates the collapse of the material often appears, slag spray, current instability, charging crusts and other abnormal conditions. For closed furnace smelting titanium slag to create the conditions. Adopting the methods of discharging slag and iron respectively, the slag and iron are separated well, which is good for the treatment of semi-steel in the next step.
