Abstract

Abstract

Taking Tanggang FTSC tudish as the prototype,tundish schemes with gas curtain installed in different position are designed. The research on flow fields of steel in the tundish and inclusion movement in different scheme shows that the gas flow rate and gas blowing position have noticeable effect on the flow fields and the inclusion movement. The parameters including T_av,V_dead,V_plug,and V_mix are obtained through RTD curve. It is believed that reasonably designed gas curtain can improve the flow fields of steel in the tundish,and the increase of residence time of steel in the tundish is favorable to the removal of the inclusions.
