摘　　要：根据离子理论,应用双膜理论,建立了LF精炼过程钢液回磷的动力学模型,并利用现场数据对模型进行拟合,确定表观速率常数和总传质系数,本模型在南钢LF精炼条件下有较好的适用性。According to the ion theory and the double membrane theory, a dynamic model of liquid steel rephosphorization in LF refining process was established, and the model was also fited by using the scene data. The constant of apparent rate and the coefficient of total mass transfer was determined. This model has good applicability in LF refining conditions.
