Thermal Crown Analysis of the Roll Sleeve in Twin-Roll Strip Casting Process

摘要

In the twin-roll strip casting process, analyses of heat transfer and deformation for the casting roll sleeve are carried out by using the finite element program ANSYS to examine the thermal crown. The effects of several factors such as molten pool temperature, heat flux onto the roll surface and roll edge, heat flux onto the cooling channels, and cooling water temperature on thermal crown are investigated. The results show that the thermal crown does not change sharply during the casting process, after the casting roll reaches thermal equilibrium.
