摘要

通过LF加石灰

控制LF末期铝含量

RH过程喷80CaO-20CaF

粉

RH终点喂铝线

RH结束后喂硅钙线等操作生产≤0.003%S的12MnV钢。根据脱硫数据表明

在110 t EAF-LF-RH-CC流程中LF平均脱硫率达88%

RH平均脱硫率不足30%;铝脱氧钢的冶炼过程中

在不喂铝丝的情况下

随S含量降低

钢中Al含量降低;在RH前钢中应有足够的Al脱除钢中的氧

以利于RH脱硫。

Abstract

The steel 12MnV with ≤0. 003% S is produced by operating such as adding lime in LF

controlling aluminum content at end of LF

injecting 80CaO-20CaF

powder in RH process and feeding aluminium wire at end of RH

and feeding calcium-silicon wire after RH process. The desulphurization data show that during the 110 t EAF-LF-RH-CC flow sheet the LF average desulphurizing efficiency is up to 88%

the RH average desulphurizing efficiency is less than 30% ; during steelmaking process for steel deoxidizing by aluminium

in non-feeding aluminium wire condition

with decreasing S content the Al content in steel decreases； and it is favourable for RH desulphurization

as there is sufficient Al in steel to dioxidize before RH process.
