为了提高钢质量,钢铁工业发达国家早在五十年代就开始了复合脱氧剂理论和应用的研究。到七十年代,苏联在重轨钢、管道用钢,欧、美、日等国在轴承、滚珠等钢种上取得了重大进展。硅锰铝、硅钙钒及钡系合金的应用也越来越广泛。 In order to improve the quality of steel, the developed countries of the steel industry began their research on the theory and application of composite deoxidizers as early as the 1950s. By the seventies, the Soviet Union had made significant progress in heavy rail steel, pipeline steel, steel in Europe, the United States, Japan and other countries in steel bearings and balls. Si-Mn-Si, Si-Ca-V and barium alloys are also used more and more widely.
