Detailed Product Description

Exerts the pre-stressed to the rolling mill, causes the rolling mill to be at the stressful condition before the rolling the rolling mill. When rolling, under the roll force function, the mill roll stand and the above spare part must have the elastic deformation. The steel rolling seat-s on a plane's elastic amount of deformity is mainly composed of the following several parts: The rack column's elasticity elongates, the crossbeam elastic bending, the housing pin and nut's elastic compression, the bearing and the bearing seat elastic compression, roller's elastic bending and the elastic compressing (sees roll flattening). Moreover, as a result of the roll force function, the rack has the elastic deformation, gap vanishing between mill housing spare part, causes to increase in the rolling instantaneous roller roller seam value, therefore the rolled piece reality rolls over thickness is:
