摘要:
近年来随着特种不锈钢、管线钢、汽车用钢、海洋钢需求量急剧增加,高钛铁合金的市场需求也越来越大,对高钛铁中氧等杂质残留量也要求越来越苛刻。另外,随着喂丝精炼技术的普及,对低氧低残留高钛铁包芯线的需求量越来越大。我国成功开发出氟盐铝热法还原制备低氧低残留高钛铁超细粉体,制备出氧含量<2.0%,铝含量<4.0%及硅含量<0.5%,钒、锰、碳、硫、磷等杂质元素含量几乎为零的高钛铁超细粉体,并在筹建万吨级规模的生产线。同时我国还开发出分步深度还原制备低氧低残留高钛铁新工艺,制备出氧含量0.23%,铝含量1.5%优质高钛铁,并在进行放大试验。

Abstract: With the increasing needs of special stainless steel, pipeline steel, automotive steel, and marine steel in recent years, the high titanium ferroalloy is becoming a great demand in the market, and the requirement of oxygen content in the high titanium ferroalloy is demanding. In addition, with the popularity of feeding refining technology, the need of high titanium ferroalloy core with low oxygen residual is becoming greater. China is developing a method of preparing ultra-fine high ti-tanium iron powder with low oxygen residual by fluoride salt aluminothermic reduction. The content of oxygen, aluminum, and silica is less than 2.0%, 4.0%, and 0.5%, respectively, and the content of impurities such as S, V, Mn, C is almost zero. And a ten-thousand-ton production line will be under construction. At the same time China is also developing a new technology of preparing high titanium ferroalloy with low oxygen residual by step-by-step reduction, of which the oxygen content in the high titanium ferroalloy prepared is 0.23% and aluminum content is 1.5%, and enlarging test is also being carried out.
