| 摘 要： | 通过LF加石灰,控制LF末期铝含量,RH过程喷80CaO-20CaF2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-20CaF2 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. |
