上钢五厂生产不锈已有20多年历史,过去一直沿用传统的返回吹氧白渣工艺。1980年11月开始试验倒包冶炼工艺获得成功。1981年8月份在倒包基础上又进一步革新,试验成功了“一步还原法一倒包”新工艺。采用这种方法不需要增加投资,提高了产品质量,氧化物合格率比原工艺提高10.87%, Stainless steel plant on the production of stainless steel has more than 20 years of history, the past has been using the traditional return of oxygen blowing white slag technology. In 1980 November began trial inverted smelting process was successful. In 1981 August on the basis of the inverted package and further innovation, the successful trial of the “one-step reduction method an inverted package” new technology. Adopt this method does not need to increase investment, improve product quality, oxide pass rate than the original process increased by 10.87%
