几十年来,用底吹转炉炼钢是西欧的一种最经济的炼钢方法。特别是可以吹炼欧洲的高磷铁矿石、其炉渣也可利用(可作磷肥——译者注)的托马斯法起着重要的作用。但是这种方法的两个重大缺点是,可加入的废钢量少和钢含氮量高。第二次世界大战后,有可能在原来用空气的地方改用氧气,同时对钢的质量要求越来越高,主要是要求降低含氮量,因此,西欧进行了各方面的努力,来发明一种新的炼钢方法,于是就产生了在转炉底部吹入纯氧的方法。但是,迅速发展的氧气顶吹转炉炼钢法终于使这种努力未能引起兴趣。氧气顶吹转炉炼钢法在短期内就在经济性方面和在质 For decades, bottling converter steelmaking is one of the most economical methods of steelmaking in Western Europe. In particular, the Thomas method, which can polish high-phosphorus iron ore in Europe and whose slag is also available, plays an important role. However, two major disadvantages of this approach are the small amount of scrap that can be added and the high nitrogen content of the steel. After the Second World War, it was possible to switch to oxygen where the air was originally used. At the same time, the quality requirements of steel were getting higher and higher, mainly because of the demand for reducing the nitrogen content. Therefore, Western Europe has made every effort to invent A new method of steel making resulted in a method of blowing pure oxygen at the bottom of the converter. However, the rapid development of oxygen top converter steelmaking finally failed to make such efforts less interesting. Oxygen top converter steelmaking method in the short term in terms of economy and quality
