硅钙钡镁代替硅铁精炼增硅脱氧的工艺研究

Technical Study on Refining with Si-Ca-Ba-Mg Alloy instead of Si-Fe Alloy to Increase Silicon and Deoxidize

文章介绍了对化学成分不要求w[Al]的钢种精炼工艺研究,研究表明,将精炼LF炉工位的增硅剂硅铁及脱氧剂铝线用硅钙钡镁合金代替,可以在不影响钢水及钢坯质量的前提下,吨钢降低生产成本6.7元,并节省钙处理所需要的约3 min时间,从而使产量提高生产成本降低。

In this paper,the refining technology for steels without requirements of w is studied.The results show that the production costs for steels per ton could be decreased by RMB 6.7 Yuan and the time of calcium treatment could be saved by 3 min.with Si-Ca-Ba-Mg alloy instead of Si-Fe alloy and aluminum wires to increase silicon and deoxidize without influencing the quality of molten steel and steel billets.As a result,the yield is increased and the production costs are decreased.
