主　　题：nozzle clogging mathematic model inclusion motion 

摘      要：The SEN clogging is a serious problem for continuous casting operation and steel *** kinetics mathematic model of SEN clogging during steel continuous casting is *** fluid flow and inclusions motion are calculated by means of mathematic *** of diameters of inclusions,roughness of nozzle,diameter of nozzle and casting speed on the entrapment probability are calculated and *** result shows that inclusions are more easily to attach to the nozzle by the following condition：smaller inclusion size,larger roughness of the wall and the smaller bulk velocity in the nozzle.
