摘要
包钢特殊渣中的CaF2和碱金属(N2O+K2O)的质量分数分别接近于2.52%和0.19%,属于低氟、低碱金属的炉渣.分析了脱硫的动力学机理,研究了脱硫动力学参数,获得1 400,1 450和1 500℃时,硫在特殊渣中的传质系数以及硫在熔渣中的扩散活化能.
The content of CaF_2 and alkali metal(Na_2O+K_2O) in the special slag of Baotou Iron and Steel(Group)Company was close to 2.52% and 0.19% respectively,which belongs to the slag of low fluorine and low alkali metal.The desulphurization dynamics between molten iron and the slag was studied,Both the diffusion activation energy of sulphur in iron liquid and the sulphur mass transfer coefficient in the special slags were obtained at 1 400,1 450 and 1 500℃.
