近几年来,氧气底吹炼钢法在国外发展很快。据报导,最近已建成或计划建设的(包括新建和改建)氧气底吹转炉有60多座,生产能力达4300多万吨。氧气底吹炼钢法拉早是在1965年由加拿大“空气液化公司”在100公斤小型实验炉上进行试验。1967年,西德马克西米利安钢铁公司引进了加拿大的这一专利,在24吨转炉上正式进行工业试验并获得令人满意的结果,这种方法命名为OBM法。1970年,法国克鲁索-罗瓦尔和文代尔-西伐尔公司改装的24吨氧气底吹转炉正式投产,称为LWS法。1971年8月美国钢
In recent years, the oxygen bottom blowing steel method developed rapidly abroad. It has been reported that more than 60 oxygen bottom blowers have been built or planned to be constructed recently (including new construction and renovation) with a production capacity of over 43 million tons. Oxygen blowing steel Farah early in 1965 by the Canadian “Air Liquefaction Company” in 100 kilograms of small experimental furnace on the test. In 1967, the West German Maximilian Company introduced the Canadian patent, formally conducting industrial tests on a 24-ton converter and obtaining satisfactory results. This method was named the OBM method. In 1970, France, Crosso-Laval and WENDEL - Xifalier converted 24 tons of oxygen bottom blowing converter officially put into operation, known as the LWS method.
