高炉冶炼低硅生铁技术的探讨

Discussion on Low Silicon Pig Iron Blast Furnace Smelting Technology

高炉冶炼过程中,降硅是一项重大节能增产措施。既可降低高炉焦比和提高产量,也可促使转炉炼钢实行无渣或少渣冶炼,从而降低炼钢成本。本文分析了国内外高炉冶炼低硅生铁的技术现状、硅的还原机理,提出了高炉冶炼低硅生铁的技术措施。

In blast furnace smelting process, reduction silicon is a significant energy saving and production enhancing meas- ures. It can reduce coke rate in blast furnace and improve the production, and also realize non-slag or less slag smelting in converter steelmaking practice, so as to decrease the cost of steelmaking. This paper analyzes the low silicon pig iron blast furnace smelting technology status quo at home and abroad, the reduction mechanism of silicon. Finally technology meas- ures for low silicon pig iron blast furnace smelting are put forward.
