Abstract Flow behavior of molten steel on the surface of mold with different corner shapes was studied by 1∶1 hydraulics model. The effects of casting speed, nozzle insertion depth and cross-sectional width on the surface velocity of molten steel in the corner of slab mold with different corner shapes were investigated. The results show that, compared with the right-angle mold, the presence of chamfered mold chamfered surface has a significant effect on the liquid velocity at the corner, and increases with the increase of the chamfered surface length. In addition, in the right-angle mold, the corner flow field changes little with various process parameters,and the fluid flow at corner belongs to the dead zone. The existence of chamfering changes the flow state of the corners, increases the flow velocity of the molten steel in the corners and benefit for improving the surface quality of the slab.

Key words： corner shape surface flow velocity mold fluid flow of corner physical simulation
