The fluid flow and the interracial phenomenon of slag and metal in tundish with gas blowing were studied with mathematical and physical modeling,and the effects of gas flowrate,the placement of porous beam for the generation of bubbles,and the combination of flow control devices on the flow and slag-metal interface were investigated.The results show that the position of gas bubbling has a significant effect on the flow in tundish,and the placement of porous beam and gas flowrate are the two main factors affecting the entrapment of slag in tundish.The closer the porous beam to the weir,the more reasonable is the flow,which is in favor of the control of slag entrapment in tundish.
