The effect of converter slag with different addition of CaO, Fe2O3 for the de- phosphorizing rate is studied though analyzing the main phases of converter slag with SEM. The result indicates the main phases of converter slag are Ca SiO , RO phase, calcium ferrite and their 2 4 combinations. The dephosphorizing rate is 29.41% while the converter slag mixes no CaO or Fe O , 2 3 and the dephosphorizing rate rises as the increase of CaO and Fe O , then the dephosphorizing 2 3 rate reaches 98.21% when the content of converter slag is 28%.
