摘　　要：Original scheme and optimizing scheme of WISCO CSP tundish have been simulated by software FLUENT. Flow field and temperature field of different schemes have been analyzed. The results which have been proved by hydraulic model experiments are the same with that of numerical simulation. It shows that the dead volume Vd of optimizing scheme decreases to 11.37%, reduced by 67.8% compared with the original scheme. The average residence time Ta of optimizing scheme increases to 639.2s, increased by 172.5s compared with the original scheme. The optimized scheme favors homogenous temperature distribution, more reasonable flow field and inclusions removing in the tundish. It is more adaptive to CSP plant of WISCO compared with the original scheme.Original scheme and optimizing scheme of WISCO CSP tundish have been simulated by software FLUENT.
