[0002] The cylinder mounting surface on the top of the arch is under the action of huge rolling force for a long time, and it also has to deal with complex and changeable working conditions. In this high-intensity, high-load working environment, problems such as corrosion, wear, and deformation gradually emerge. The corrosion phenomenon damages the mounting surface of the top of the arch, reducing its structural stability and durability; wear leads to a decrease in the matching accuracy of the top mounting surface of the arch and related components, affecting the flatness of the rolled steel plate; and the deformation problem directly interferes with the normal operation of the finishing mill, making it difficult for the product's dimensional accuracy and surface quality to meet the expected standards, thereby failing to guarantee the stability and reliability of product quality.

[0003] Traditional maintenance methods used to address these problems have many drawbacks. Usually, the support rolls need to be disassembled from the finishing mill, which is a very cumbersome operation. The top cylinder needs to be removed and then the platform needs to be set up, and finally the machine tool needs to be processed and repaired online. This method firstly consumes a lot of manpower and material resources to complete a series of tasks such as disassembly, platform setting up and reinstallation. Secondly, this cumbersome processing and repair means that the production line must be shut down for a longer period of time, during which normal production activities cannot be carried out.
