Mold corner structure will control the strand corner temperature by changing fluid flow and heat transfer of molten steel at mold corner. A three-dimensional model coupling fluid flow and heat transfer in the mold and a two-dimensional moving-slice heat transfer model in secondary cooling zone was established to investigate slab corner temperature under different mold corner structure: right-angle, big-chamfer, multi-chamfer and fillet. Results showed that slab corner temperature increased markedly at mold exit through using chamfered mold. Compared with the corner temperature of right-angle slab, corner temperature of big-chamfered, multi-chamfered and fillet slabs were promoted during the straightening process, which would avoid the low ductility temperature zone. When mold corner structure changed from right-angle to big-chamfer, the rise of corner temperature was much higher than that changed from big-chamfer to multi-chamfer or fillet. Furthermore, the corner temperature variation by changing the mold corner structure gradually reduced in secondary cooling zone.
