Abstract
The continuous casting process has been adopted increasingly in recent years to save both energy and labor. It has experienced a rapid development in the production of semi-finished steel products, replacing the conventional route of ingot casting plus rolling. To achieve this good merit, however, more studies about thermal and dynamical interactions between roll and slab are needed. So this paper shows the results of the dynamic bulging in thin slab casting, which is one of the critical factors in designing and operating the continuous casting machine. The dynamic bulging between two supporting rolls under ferro-static pressure and slab-self weight has been computed in terms of creep and elastic-plasticity. The strain and strain rate distributions in solidified shell undergoing a series of bulging are calculated with working boundary conditions.
