用CaO-Fe_2O_3-CaF_2-Al_2O_3-Na_2CO_3渣系,不同的(CaO+Na_2CO_3)/Fe_2O_3,CaF_2,Na_2CO_3含量及以BaO部分代替CaO对铁水预处理脱磷进行了实验研究,结果表明,当脱磷熔剂中(CaO+Na_2CO_3)/Fe_2O_3为0.8～1.05;CaF2含量达到8%～11%;Na_2CO_3用量达10%～12%;BaO配入量为10%～17%时都能取得较好脱磷效果。其脱磷率可达80%～85%。
The experimental study on dephosphorization of molten iron pretreatment with CaO-Fe_2O_3-CaF_2-Al_2O_3-Na_2CO_3 slag system with different contents of (CaO + Na_2CO_3) / Fe_2O_3, CaF_2, Na_2CO_3 and BaO instead of CaO showed that when dephosphorization The content of CaO + Na_2CO_3 / Fe_2O_3 is 0.8 ~ 1.05, the content of CaF_2 is 8% ~ 11%, the amount of Na_2CO_3 is 10% ~ 12%, and that of BaO is 10% ~ 17% effect. The dephosphorization rate of up to 80% to 85%.
