Description
Technical Field

Background
The manufacturing of the roll involves a series of processes including forging of a blank, heat treatment, rough machining, semi-finishing, etc. In the manufacturing process of the shaft roller, because the situation of uneven stress distribution possibly exists in the shaft roller, certain deformation can be generated after rough turning of a shaft roller blank; in addition, the shaft roller blank needs to be welded when surface defects are found after rough turning, and certain deformation can also occur after welding. When the deformation of the shaft roller exceeds a certain value, the subsequent processing is difficult, and the local allowance of the shaft roller is too small to be processed. In this case, the shaft roller needs to be corrected to ensure a subsequent machining allowance. There are generally two types of correction methods: one is cold correction, that is, acting force is locally applied to the shaft roller under the condition of not heating the shaft roller, so that the shaft roller generates certain plastic deformation, and the cold correction is suitable for the condition of small deformation amount; the other is local thermal correction, namely, force application correction is carried out after the shaft roller is locally heated, and the method is suitable for the condition with large deformation. In order to ensure the dimensional stability of the corrected roller, a certain stability treatment (such as stress relief aging) is usually required after the roller is corrected, and then the subsequent processing is carried out.
The existing small and medium-sized shaft roller deformation correction method comprises the following steps: the beam barrel was positioned on a pair of V-shaped irons, held in compression with a platen, and then tapped with a hammer.
