The results show that with the increase of strain rate, the grain sizes of thermal simulation AZ31B alloys with different deformation all decrease; however, when other conditions are the same, the higher deformation will lead to the formation of the smaller grain size, and as the cooling intensity decreases, typical cast structure of AZ31B will appear. With the decrease of roll casting temperature, the dendritic size of roll casting AZ31B alloy sheet prepared by the same strain rate is also reduced, but with the increase of strain rate, the dendritic size of the alloy sheet prepared by the same initial roll casting temperature is decreased, and the tendency of dendritic streamline is strengthened. During the roll casting process of AZ31B alloy, rolling force should not be large, otherwise it will cause heat cracking.
