顶底复合吹炼是国外七十年代末期发展起来的一项新技术。它综合了顶吹、底吹转炉的特点,很快引起了各国冶金界的重视,发展迅速,到八十年代已进入工业生产,1982年末工业发达国家已有九十余座转炉改为顶底复合吹炼法炼钢。在我国也开展了此项研究,并已取得成果。 鞍钢、首钢、新抚等钢厂已分别对150吨、30吨、和6吨氧气转炉改造,进行复吹
Top and bottom compound blowing is a new technology developed in the late seventies. It combines the top blowing, blowing the characteristics of the end of the converter, and soon attracted the attention of all countries in the metallurgical industry, rapid development, to the eighties has entered industrial production, industrialized countries in late 1982 have been more than 90 converter top to bottom Compound blowing method of steelmaking. This research has also been carried out in our country and has achieved results. Anshan Iron and Steel Company, Shougang, Xin Fu and other steel mills have respectively 150 tons, 30 tons, and 6 tons of oxygen converter transformation, complex blowing
