摘　　要：采用最佳子集和回归等数据处理方法,对钢液部分氧化元素的活度与氧的传质通量进行了建模。建立了大气氧氛条件下钢液传输过程增氧行为的动力学计算基础,对分析钢种浇注过程的二次氧化的增氧差异有一定的借鉴意义。Data processing methods such as optimal subset and regression have been used to model the activity of partially oxidized elements in molten steel and the mass transfer flux of oxygen.The kinetic calculation basis for the oxygen-enhancing behavior during the transport of molten steel under the atmospheric oxygen atmosphere has been established,which has certain reference significance for analyzing the oxygen-enhancing difference of the secondary oxidation during the steel pouring process.

关 键 词：氧化元素 活度 浇注 二次氧化 氧传质通量
