一、前言 设计冷轧带钢张力卷取机的关键是卷筒结构和胀缩机构的选型以及力参数的计算。力参数主要是计算卷筒在按工艺要求缠绕最大钢板层数时,卷筒表面所承受的最大径向负荷。并由此作为卷筒另件强度刚度的计算和确定胀缩机构作用力的依据。 I. Preface The key to design cold rolling strip tension coiler is the selection of the reel structure and expansion and contraction mechanism as well as the calculation of the force parameters. The main parameter of the force is to calculate the maximum radial load on the surface of the roll when the maximum number of layers of the roll is wound according to the technological requirements. And as a basis for the calculation of the stiffness stiffness of the roll pieces and the determination of the force of expansion and contraction mechanism.
