【摘要】:本文研究了在渣堿度為2.4時(shí),不同預(yù)處理溫度、時(shí)間對(duì)磷礦熔態(tài)還原反應(yīng)的影響,結(jié)果表明在預(yù)處理溫度為800℃、時(shí)間為20min、熔態(tài)還原溫度為1300℃,反應(yīng)時(shí)間為1h時(shí)的還原率為94%。對(duì)預(yù)處理后的磷礦進(jìn)行了熱重分析,從磷礦還原反應(yīng)機(jī)理出發(fā)說明預(yù)處理過程有利于加快磷礦石的還原反應(yīng),使磷礦石在熔態(tài)環(huán)境能夠快速分散,增加反應(yīng)物的活性,進(jìn)而提高磷礦在還原反應(yīng)過程中的還原率。
[Abstract]:In this paper, the effect of different pretreatment temperature and time on the melting state reduction of phosphate rock was studied when the slag alkalinity was 2. 4. The results showed that the reduction rate was 94 when the pretreatment temperature was 800 鈩,
