在热力学计算及动力学条件分析基础上,提出了向硫化物熔体中吹入具有一定氧分压的气体以提高固体废钢脱铜效果的方法.氩气搅拌及静态实验对比结果表明,在熔渣组元质量分数为FeS-70%,Na,S-30%,950℃下在反应初期氩气搅拌可明显地提高脱铜速度.这是因为氩气搅拌提高了物质的扩散速度.
Based on the thermodynamic calculation and kinetic analysis, a method of blowing gas with a certain oxygen partial pressure into the sulfide melt to improve the copper removal efficiency of solid scrap was proposed. The results of argon stirring and static experiments show that in the melt Slag component mass fraction of FeS-70%, Na, S-30%, 950 ℃ at the initial reaction of Ar gas stirring can significantly increase the rate of copper removal, this is because the argon stirring to improve the material diffusion rate.
