摘要
采用石灰系熔剂处理低硅、高锰,中磷铁水,以研究锰和磷的氧化。实验结果表明:在1573～1623K,铁水中[％Mn]>0.32时,锰比磷优先发生氧化;当[％Mn]<0.32时,磷比锰优先发生氧化。为了能顺利地进行脱磷,必须将铁水中的锰脱除到0.3％以下。通过热力学计算,从理论上也证实了上述锰和磷的氧化规律。
The Oxidized relation between Mn and P in pretreatment of hot metal containing low Si, high Mn and mid P by using lime-based flux was investigated. The results show that when [%Mn] is above 0.32, Mn is more preferential oxidized than P, and when [%Mn]is low 0.32, the result is contrary to one above mentioned at 1573-1623K. The Mn content which is low 0.3% in hot metal is necessary in order to obtain the sufficient dephosphorization.
