摘　　要：以铁水和脱磷粉剂为研究体系,应用CaO-Fe2O3-CaF2渣系的脱磷粉剂和其预熔渣对铁水脱磷,研究结果表明,用Al2O3和白云石部分替代萤石,预熔后的脱磷渣都比未预熔渣的脱磷速度快,且二者的处理过程结果基本相似,脱磷粉剂经过预熔处理,成渣迅速,预处理时间缩短,温降小,脱磷率高。The present paper studies the hot metal dephosphorization using the CaO-Fe2O3-CaF2 slag series and its premelted slag as dephosphorizer. Results indicate that by substitution of the fluorite with Al2O3 and dolomite the dephosphorizing rate of the premelted slag is higher than the non-premelted one and the dephosphorization process and results are similar for both of them. It＇s concluded that the premelted dephosphorizing powder has the advantages of quick slag formation, short pretreatment time, low temperature drop and high dephosphorization rate.
