| Abstract: | With the aid of elastic-plastic and thermal-mechanical coupled model,the variation of the shrinkage ratio of liquid core and the reduction force of roll under different central solid fraction and different reduction amount have been studied.At the same time,the effects of reduction technique parameter on internal crack of bloom have been analyzed.Therefore,the dynamic reduction scheme is provided. |
