Abstract：The H-Beam blank continuous casting mould was taken as the research object and the effect of casting speed on its steel flow behavior was studied.The results show that,with the increase of casting speed,the vortex formed in the mold moved down gradually,the flow field velocity became more uniform and the liquid surface velocity of the slag-gold became higher.However,for the straight nozzle,the jet depth gets larger and larger,and the inclusions are not easy to float.Therefore,it is necessary to determine the optimal casting speed range.It should not only provide the necessary time and space conditions for the flotation of inclusions to ensure their sufficient separation and removal,but also take into account the uniformity and stability of the flow field to guarantee the consistent internal quality of the cast billet.
