    摘要
  • 摘要: 在熱力學計算及動力學條件分析基礎上,提出了向硫化物熔體中吹入具有一定氧分壓的氣體以提高固體廢鋼脫銅效果的方法.氬氣攪拌及靜態實驗對比結果表明,在熔渣組元質量分數為FeS-70%,Na2S-30%,950℃下在反應初期氬氣攪拌可明顯地提高脫銅速度.這是因為氬氣攪拌提高了物質的擴散速度.

     

    Abstract: An novel approach has been proposed for treating solid ferrous scrap with sulphide matte by blowing the gas with a controlled low oxygen pressure to promote the removal of copper. It has been proved by comparison of the result of the experiment by blowing argon at 950℃ with those of the static experiments that argon stirring can remark-ably increase the rate of copper removal at the initial stage of the treatment, for the matte of 70% FeS and 30% (mass fraction).
