摘要
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 of different (CaO +Na 2 CO 3 )/Fe 2 O 3 ,CaF 2 ,Na 2 CO 3 contents and the content of BaO partly replaced CaO in CaO -Fe 2 O 3 -CaF 2 -Al 2 O 3 -Na 2 CO 3 slag system on dephosphorization fo r hot metal treatment rate was performed .When(CaO +Na 2 CO 3 )/Fe 2 O 3 ratio was 0.8~1.05,the content of Ca F 2 was 8%~11%,the content of Na 2 CO 3 was10%~12%and the content of BaO partly replaced CaO was 10%~17%,it all could obtain good dephosphorizatio n result.The dephosphorization ratio of 80%~85%was achieved.
