【Abstract】 The article analyses the thermodynamic conditions of reducing dephosphorization and calculates the theoretical dephosphorization efficiency. In addition, dephosphorization experiments of stainless steel 2Cr13 with CaC 2-CaF 2 slag were made in vacuum induction furnace. The results showed that the slag was powerful in its capacity of deoxidation and desulfurization as well. When the mass of CaF 2 was about one fourth of CaC 2, the dephosphorization results were the best with a high dephosphorization rate of 75.3?%. As a result, the final phosphorus content of stainless steel can be decreased to about 0.01?%.更多还原
