| Abstract: | In the twin roll strip casting process, coupled analyses of heat transfer and deformation for the casting roll are carried out by using the finite element program MARC to examine the thermal crown. The shrink fit effect and plastic deformation are considered. The result shows that the thermal crown is greatly influenced by the shrink fit and that the thermal crown for POSCO Pilot Caster 2 Copper Roll has an “M” shape. The effects of several factors on thermal crown are also investigated. The amount of thermal crown increases as the heat flux, casting speed, sleeve thickness and casting roll width increase. On the other hand, it decreases as the casting roll diameter increases. |
