摘　　要：通过热力学分析,结合HSC热力学软件计算结果,发现C6H12O6、CaCl2和SiO2在一定程度上能够促进高磷钢渣中磷酸钙分解,实现气化脱磷。借助微型烧结实验手段,试探性研究了不同脱磷剂对气化脱磷率的影响。结果表明,用C6H12O6、CaCl2、SiO2配比分别为0.18%、0.29%和0.69%的混合物作脱磷剂,烧结过程中气化脱磷率能达到40.5%。结合生产成本考虑,是比较适宜的。Through the thermodynamic analysis and in combination with calculation results of HSC thermodynamics software,it is found that C6HI2O6, CaCl2 and SiO2 can promote the decomposition of calcium phosphate in high phosphorus- bearing steel slag to some extent to realize the gasification dephosphorization. With the aid of micro sintering experiment means, the influence of different dephosphorization agent on gasification dephosphorization rate is studied. The research results show that, using the mixture with 0. 18% C6H12O6, 0.29% CaCl2 and 0.69% SiO2 as dephosphorization agent, the gasification dephosphorization rate can reach 40. 5% in the sintering process. In consideration of the production cost, the method is appropriate.
