| 摘 要： | 针对w([P])在0.33%~0.44%的中磷铁水,在1 350℃条件下采用喷吹法对同时脱磷脱硫渣系进行了优化试验。结果表明:CaO过剩系数、氧化剂过剩系数和w(CaF_2)/w(CaO)对脱磷的影响不大,但对脱硫影响显著。综合考虑脱磷率、脱硫率和渣量,最佳渣剂组成为CaO过剩系数45%,氧化剂过剩系数15%,w(CaF_2)/w(CaO)为0.5;用B_2O_3代替CaF_2,须将w(B_2O_3)/w(CaO)控制在0.20以上。 |

| Abstract: | In view of medium-phosphorus hot metal with the phosphorus content between 0.33 ％ and 0.44 ％,a optimization test on simultaneous dephosphorization and desulfurization slag system was carried out by injection treatment at 1 350 ℃.The results showed that CaO excess coefficient,oxidizer excess coefficient,and ω(CaF2)/ω(CaO) ratio had little effect on dephosphorization,but influenced desulphurization quite appreciably.With the combined consideration to dephosphorization rate,desulphurization rate,and slag quantity,the optimum agent composition was CaO excess coefficient of 45 ％,oxidizer excess coefficient of 15 ％,and ω (CaF2)/ω (CaO) of 0.5.To substitute B2O3 for CaF2,the ω(B2O3)/ω(CaO) ratio should be maintained above 0.20. |
