摘要
在 P_(co)=1atm,1300℃条件下研完了 CaO-CaF_2-SiO_2三元渣用作中磷铁水预处理熔剂进行脱磷脱硫的特性。研究结果表明:CaO饱和的 CaO-CaF_2-SiO_2三元渣具有很强的同时脱磷脱硫能力,组成为48%CaO、22%SiO_2、30%CaF_2的渣的磷容量为10^(25),硫的分配系数10~3以上。
The properties of CaO-CaF_2-SiO_2 slags were investigated at Pco=1 atm and 1.300℃.The object is to use CaO-C_aF_2-SiO_2 slags as a dephos- phorized and desulphurized flux for pretreatment of medium and low phosphorus hot metal. The experimental results showed:The C_aO-C_aF_2-SiO_2 fluxes saturated by C_aO and 3C_aO·SiO_2 simultaneously have high ability of dephosphoriza- tion and desulphurization.The phosphate capacity and sulphur distribution coeffici ent of slag consisted 48%C_aO,22%SiO_2,30%C_aF_2 are 10^(25) and hig- her than 10~3 respectively.
