[0002] In the machinery manufacturing and mechanical equipment manufacturing industries, when producing circular cylindrical rotating parts, the parts often experience irregular deformation in the diameter direction due to welding stress after rolling and butt welding, resulting in local roundness deviation or cylindrical deviation along the length direction, which makes it impossible to accurately position or assemble during subsequent assembly.

[0003] In order to correct the deformation of circular cylindrical rotating parts, production units usually make special correction tires according to the external dimensions of the cylindrical rotating parts. Generally, they are of top-type structures and can only perform partial corrections. They also need to be repeatedly tested and the correction position needs to be adjusted continuously, and they are not easy to detect. In addition, the correction tires have high manufacturing costs, are not very applicable, and are prone to waste.
