- 摘 要
- 本文论述了国内各钢厂生铁硅的质量分数的控制情况。分析了莱钢炼铁厂生铁硅含量偏高的原因。通过改进震筛组成,提高炉渣二元碱度,抑制Si还原等措施,将生铁含硅降到0.4%以下,成功进行低硅冶炼,取得良好的经济效益。

- Abstract
- This paper discusses the control situation of the domestic pig iron silicon content. The causes of high silicon content in pig iron of the ironmaking plant are analyzed. The silicon content of the pig iron is reduced to less than 0. 4%,and the success of low silicon smelting is achieved,and,good economic benefits is obtained by adopting some measures,such as improving vibration sieve,increasing slag basicity,inhibiting Si reduction and other measures.
- Keywords
- BF; slag-making; low silicon smelting
