Abstract In certain conditions of dephosphorization agent type and proportion, with the help of micro sintering experiment 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 dephosphorization rate of steel slag decreased, improving the temperature, gasification dephosphorization rate rose, with the increased amount of carbon in steel slag, the rate of gasification dephosphorization first increased and then reduced, increasing the phosphorus content, gasification dephosphorization rate increased，and when the phosphorus content reached a certain level, the effect of phosphorus content on the gasification dephosphorization rate was weakened, and ultimately determine the optimum state of each factor.
