| 摘 要： | 根据冶金熔体的共存理论,计算了CaO-MgO-MnO-FeO-SiO2-Al2O3六元渣系各组元的作用浓度。结合生产实际数据,建立了LF精炼过程中炉渣成分和钢水Ca]之间氧化还原反应的数学模型,计算了炉渣成分对钢水Ca]含量的影响。结果表明,LF精炼过程中钢水Ca]含量受Si]-(FeO)联合控制,渣中SiO2、FeO质量分数每增加1%,Ca]质量分数分别降低1.63×10-6和1.55×10-6。为了将Ca]质量分数控制在10×10-6以下,当FeO质量分数为3%左右时,碱度B应不高于0.9。 |

| Abstract: | According to the coexistence theory of slag structure,Mass action concentrations for CaO-MgO-MnO-FeO-SiO2-Al2O3 melts was calculated.Based on the practical data,a mathematical model of oxidation-reduction of Ca] under some slag conditions in LF refining process has been deduced.The influence factors about Ca] contents with different slag compositions were calculated.The results show that the Ca] contents are controlled by Si] and(FeO).When the mass contents of SiO2 and FeO in the slag increased 1%, Ca]... |
