| 摘 要： | 分析了不锈钢还脱磷的热力学条件，计算了脱磷率，并在真空感应炉中用CaC2-CaF2熔剂对2Cr13重熔钢液脱磷进行了实验研究。实验结果表明，这种渣有很强的脱氧和脱硫能力。当CaF2和CaC2的质量比接近1：4时，脱磷效果最好，最大脱磷率可达75．3％，并可使最终wp降至0．01％左右。

| 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?%. |
