摘　　要：基于现有生产线条件,提出了采用AOD炉用海绵钛替换钛铁冶炼含钛钢炉内合金化的方案,通过试验海绵钛收得率比钛铁收得率提高7%左右,减少了AOD合金加入量,可以降低AOD炉氧化终点温度30℃左右,进而减少了高温对耐材的侵蚀。Based on the condition of production line, the scheme of AOD furnace smelting with sponge titanium to prepare titanium-hearing steel instead of titanium fercum is put forward. The yield of titanium sponge is about 7%higher than that of ferrotitanium sponge. By reducing the amount of AOD alloy, the oxidation terminal temperature of AOD furnace can be reduced by about 30 ℃, and the corrosion of refractories at high temperature can be reduced.
