前言矿热炉冶炼75％硅铁时,产生一定量的炉渣,此种炉渣由于含有碳化硅、游离态硅以及少量75％硅铁金属粒,因而可作为炼钢还原期造白渣的一种扩散脱氧剂。我厂最近分别采用75％硅铁粉与硅铁渣粉作扩散脱氧剂,对炼钢的各种工艺参数及钢种质量做了对比试验,对硅铁渣作扩散脱氧剂的原理进 Preface When smelting 75% ferrosilicon in a submerged arc furnace, a certain amount of slag is generated. Such a slag can be used as a diffusion of white slag during the steelmaking reduction period due to the inclusion of silicon carbide, free silicon and a small amount of 75% Deoxidizer. I plant the recent use of 75% ferrosilicon powder and ferrosilicon slag powder as a diffusion agent, the various steelmaking process parameters and the quality of the steel made a comparative test of the principle of diffusion of ferromanganese slag deoxidation agent into
