摘      要：Powder injection is widely used in hot metal pretreatment. The kinetic analysis of refining process shows that the reagent utilization and pretreatment efficiency are determined by the penetration ratio of powder into metal, the residence time of powder in the metal bath, as well as the uniform mixing time of the bath. The characterization of these parameters is studied with water model experiment, and, a mathematical model is developed for hot-metal dephosphorization in torpedo car. Water-model experiment results and industrial data are used to determine the model parameters and verify this model, the results show that the prediction from the model agrees well with practical results.
