【Abstract】 According to the characteristics of the roll shell′s heat transfer in the continuous roll casting, a mathematical model for the roll shell′s temperature field was presented. An approximate analytical solution for the temperature field was obtained with Galerkin method,and the analytical results conformed with the measured values in the worksites. The roll shell′s temperature distribution in the high speed thin gauge twin roll casting was simulated. The simulation shows that the largest temperature between the roll shell′s inner surface and its exterior surface is cut down apparently, and that the temperature distribution is more balanced in the high speed thin gauge twin roll casting than in the continuous roll casting.更多还原
