摘要： 将钢铁冶金中的多组分同时反应作为一个综合的反应体系进行研究，考虑其中各反应间的影响. 根据冶金热力学和动力学原理建立多组分渣-金-气反应体系同时反应动力学模型，编制计算程序，得出成分对时间的变化曲线，并用含Fe-Cr-Mn-C的渣-金反应体系的实验进行了验证. 结果表明，金属液中C和Mn组分的计算浓度与实测值基本吻合，Cr的计算浓度与实测值的相对误差在9.1%以内. 在直流电弧下熔炼存在大气通过渣层向金属液的传氧现象，其数值与大气向钢液直接传氧的数值相同. 采用模型方法能较好地解释过程中的反应现象，揭示过程的机理.

Abstract: The simultaneous reactions in a multi-component system in ferrous metallurgy as a comprehensive reactions system were investigated. The interaction between the various components on reactions was considered. A kinetic model of simultaneous reactions in a multi-component metal-slag-gas reaction system was established using metallurgical thermodynamics and kinetics. A computer program was designed to obtain the variation curves of concentrations of components with reaction time. The simulation data were verified by experimental results. The results showed that the calculated data by the kinetic model of simultaneous reactions in the system were consistent with the experimental results of Fe-Cr-Mn-C system. This modeling method for predicting the concentration of each component in the metal-slag reaction system was feasible, and could well explain the phenomena and reveal the process mechanism.
