摘　　要：通过对炉渣脱硫热力学与动力学参数(包括硫容量、硫分配比、黏度和硫在渣中的扩散系数)计算公式的推导分析,理论计算炉渣化学成分,如m(CaO)/m(Si O_(2))、w(MgO)、m(MgO)/m(Al2O3)和w(MnO),对脱硫热力学和动力学参数的影响。研究结果表面,炉渣硫容量和硫分配比随m(CaO)/m(Si O_(2))、MgO和w(MnO)的增加而升高。炉渣黏度随m(CaO)/m(Si O_(2))和w(MnO)的增加而降低。炉渣w(MgO)和m(MgO)/m(Al2O3)与黏度的关系均存在拐点(w(MgO)=14%,m(MgO)/m(Al2O3)=0.9),拐点前后的影响趋势相反。This article deduced and analyzed the calculation formulas for thermodynamic and kinetic parameters of slag desulfurization(including sulfide capacity,sulfur distribution ratio,viscosity,and sulfur diffusion coefficient in the slag),and theoretically calculates the influence of slag chemical composition,such as m(CaO)/m(SiO_(2)),w(MgO),m(MgO)/m(Al_(2)O_(3)),and MnO,on desulfurization thermodynamic and kinetic parameters.The research results indicate that the sulfide capacity and sulfur distribution ratio of the slag increase with the increase of m(CaO)/m(SiO_(2)),w(MgO),and w(MnO)content.The viscosity of slag decreases with the increase of m(CaO)/m(SiO_(2))and w(MgO).There is a turning point in the relationship between viscosity and w(MgO)content,m(MgO)/m(Al2O3),in slag(w(MgO)=14%,m(MgO)/m(Al_(2)O_(3))=0.9),and the trend of influence before and after the turning point is opposite.
