Abstract With CaO-Fe2O3-CaF2 system slag as dephosphorization，the influencing factors of such for ratio，temperature，addition rate，basicity of slag was studied in laboratory GSL for dephosphorization．As a result，when the w（CaO）/w（Fe2O3）=2.5，the basicity is 2.5，the flux were added in an amount of 12% and addition some flux rate，so that the phosphorus content decreased to 0.47% in temperate conditions of 1450℃．Finally，the best ratio was derived dephosphorization by adjusting the amount of flux．
