摘要: 研究了铁水温度、铁水初始硫含量、搅拌时间、旋转速度和脱硫剂加入量对80 t KR铁水预处理装置脱硫效果的影响。结果表明,提高铁水温度,则增大脱硫效果;在铁水硫含量为0.043%-0.046%、铁水温度为1 290~1 310℃时,加入600~650 kg脱硫剂(铁水温度1 340~1 350℃时,加入450-550 kg脱硫剂),搅拌时间5-8 min,旋转速度85~90 r/min,具有较佳的脱硫效果。

Abstract: The effect of metal temperature, initial sulfur content in metal, stirring time, rotational speed and adding amount of desulphurizer on desulphurization results of an 80 t KR hot metal pretreatment unit has been studied. The results showed that with increasing metal temperature the desulphurization effects increased, and with 0.043% ~ 0.046% S in metal, metal temperature 1 290 〜1 310 °C, adding desulphurizer 600 〜650 kg (metal temperature 1 340 〜1 350 T, adding 450 ~ 550 kg), stirring 5 ~ 8 min at rotational speed 85 ~ 90 round/min, the desulphurization effects were better.
