摘　　要：在脱磷剂种类和配比一定的条件下,借助微型烧结实验手段,研究了碱度、温度、配碳量和磷含量等因素对高磷钢渣气化脱磷率的影响规律。研究发现,碱度升高,钢渣气化脱磷率降低,温度升高,钢渣气化脱磷率升高;随着配碳量增加,钢渣气化脱磷率先升高后降低,磷含量增加,钢渣气化脱磷率升高,当磷含量达到一定水平后,磷含量对气化脱磷率的影响减弱,并最终确定了各因素的最佳状态。In certain conditions of dephosphorization agent type and proportion, with the help of micro sintering experi- ment method, the basicity, temperature, carbon and phosphorus content on the influence of gasification dephosphorization rate of high phosphorus steel slag was studied. The studies have shown that increasing the alkalinity, gasification dephos- phorization rate of steel slag decreased, improving the temperature, gasification dephosphorization rate rose, with the in- creased amount of carbon in steel slag, the rate of gasification dephosphorization first increased and then reduced, increas- ing the phosphorus content, gasification dephosphorization rate increased, and when the phosphorus content reached a cer- tain level, the effect of phosphorus content on the gasification dephosphorization rate was weakened, and ultimately deter- mine the optimum state of each factor.
