苏联图拉钢铁科学技术研究所发明了一种转炉冶炼100％废钢的新技术。该技术的主要特点是转炉采用复合吹氧:除了在底部吹氧之外,顶部和侧部还装有喷枪——喷吹氧气、天然气和碳化氢等燃料,这种技术最初在公称容量10吨的转炉中获得成功,从而取消了铁水装兑工序。近几个月来已经实现了全部使用废钢进行冶炼。废钢使用率为50％和超过50％的场合,使用天然气和煤粉,尽管煤粉中的含硫量为2％,但是这种新技术仍能生产含硫量0.015～0.030％的钢种,冶炼100％废钢时可以把 The Soviet Union Tula Steel Institute of Science and Technology invented a converter smelting 100% scrap new technology. The main feature of this technology is the use of composite oxygen blowing converter: In addition to blowing oxygen at the bottom, the top and side also equipped with a spray gun - blowing oxygen, natural gas and hydrocarbons such as fuel, this technology initially nominal capacity of 10 tons The success of the converter, thus eliminating the hot metal process. In recent months, scrap metal has been used for smelting. The use of natural gas and pulverized coal at 50% and more than 50% scrap utilization, despite the 2% sulfur content in the pulverized coal, still produces 0.015-0.030% sulfur steel, Smelting 100% scrap can be put
