摘要
通过对转炉冶炼过程中耗氧比模型的比较及Mn,Si,P氧化机理的分析,应用冶金热力学和动力学建立了耗氧比模型,并根据生产数据的检验结果与模型预测结果的一致性,得出如下结论:供氧强度决定Mn,Si,P的氧化速率;Mn,Si,P在熔池中扩散系数和初始含量的大小将决定各自耗氧比的起始大小;温度通过反应平衡常数影响耗氧比.
Based on the comparison of different oxygen distribution models and the analysis of the oxidation mechanism of Mn, Si and P in BOF refining process, an oxygen distribution model, based on both thermodynamics and kinetics is established. Verification of the model with practical data shows that the model prediction agrees well with practical process and the following conclusions are obtained： The oxidation rates of Mn, Si and P are determined by the intensity of oxygen supply. The oxygen distribution is determined mainly by the diffusion coefficients and initial contents of Mn, Si and P in the bath ; and it is also affected by temperature through the reaction equilibrium constants.
