Description
Technical Field

[0002] Roller straightening is the correction of shape defects caused by repeated bending of the rolled material when it passes between two rows of staggered rollers. Roller straightening is carried out on a roller straightener or an inclined roller straightener. Roller straighteners are widely used for straightening plates, strips and profiles, while inclined roller straighteners are used for straightening tubes and bars. Among rolled products, except for some large-section rolled products whose shape defects are manifested as initial curvatures with the same value and direction, the shape defects of most rolled products are manifested as the original curvatures with uncertain values and directions. For the latter type of rolled products, after elastic-plastic rebending with the same curvature, the residual curvature has the characteristic of tending to be consistent, and can be straightened after appropriate rebending. The curve of two sections of initial curvatures with different directions on a rectangular section rolled product of ideal elastic material is straightened after three rebending.
