该系列矫平机的特色之处在于：采用分组驱动板材矫正机(ZL200420001176.0)和一种轴装式减速电机矫平机(ZL200520007514.6)两种国家专利技术，每根上辊由一套减速电机驱动，每两根下辊由一套动力系统驱动，从而使各辊的线速度与所接触部位的板料速度相一致，消除了传统传动系统存在的板料与辊面之间的摩擦和传动系统内部的机械干涉问题，同时由于工作辊的轴承均采用轧机用调心辊子轴承，摩擦阻力小，因此，该系列矫平机与传统矫平机相比，矫平质量高、噪音小、能耗低、节能环保。

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.
