At the same time, the pouring billets experiment was also executed based on the simulation results. The results indicate that the casting speed and pouring temperature are the most important parameters to determine that a high speed steel composite roll billet can be well poured or not and the quality of interface of bimetal composite is better or not. Increases in pouring temperature and casting speed are conducive to metallurgical bond between the two metals, but their moreincreasing will make the depth of melting zone increase, the thickness of solidifying shell decrease and the feasibility of breakout increase. The simulated appropriate pulling temperature and casting speed are about 1873—1923 K and 0.3—0.5 m/min, respectively, which are proved by experiment results. Key words:  high speed steel composite roll      continuous pouring process for cladding      temperature field      interface of bimetal composite      Received:  02 April 2011      Fund:  Supported by National High Technology Research and Development Programme of China (No.2003AA331050) and National Natural Science Foundation of China (No.200809123) Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors FENG Meng-Jie YU En-Gang YU Jun-Gang SHI Ji-Cheng URL:  https://www.ams.org.cn/EN/10.3724/SP.J.1037.2011.00194     OR     https://www.ams.org.cn/EN/Y2011/V47/I12/1503 [1] Walmag G, Skoczynski R J, Breyer J P.
