热轧地下卷取机牌坊式转向夹送辊设计

在热轧地下卷取机牌坊式转向夹送辊设计过程中,针对下夹送辊的辊径大小、上辊压下力大小难确定的问题,本文参照热轧卷筒最小直径的计算方法,确定下辊的最小直径;把带钢的夹送过程假设成轧制过程和弯曲过程的合成,按轧制理论计算的轧制力其值等于夹紧力值;把带钢弯曲简化成悬臂梁,并用矫直弹塑性理论进行建模,计算的上辊弯曲力值等于压下力值,并用实例验证上辊压下力大小的合理性。

Design analysis of archway type deflector pinch roll of hot rolling down coiler

In the design of the archway type deflector pinch roll of a hot rolling down coiler,a method referenced with the algorithm of hot rolling winding drum minimal diameter is proposed to determine the minimal diameter of lower roll according the rolling theory to solve the problems that the dimention of lower roll diameter and the push-down force of upper roll are difficult to be determined.Meanwhile,the pressing-sending process of strip steel was presumed as a composite of the rolling process and bending proce...
