引言周期轧机热轧钢管时,金属作用于轧辊上的力和力矩是确定和使用轧机的主要参数。轧机各零件尺寸的确定及主电机容量的选择无不以上述参数为准则。因此,正确的确定轧制时金属作用于轧辊上的力和力矩,是一项十分重要的任务。此外,为了充分发挥现有的设备能力,提高轧机生产率,对于在喂入量、机辊转数、轧制温度、毛管尺寸等有所变化的情况下也必须求出实际作用力和力矩,进而计算各零件中应力的大小,以便了解轧机能力的利用程度。
Introduction Cycle mill hot-rolled steel pipe, the metal on the roller force and moment is to determine and use the main parameters of the mill. Mill parts to determine the size and selection of the main motor capacity of all the above criteria. Therefore, it is a very important task to correctly determine the force and moment that the metal acts on the roll during rolling. In addition, in order to give full play to existing equipment capabilities and increase rolling mill productivity, it is necessary to find the actual acting force and moment when there is a change in feeding amount, number of machine rolls, rolling temperature, capillary size and the like, Calculate the size of the stress in each part to understand the degree of utilization of mill capacity.
