[0002] The slab continuous casting roller is one of the core components of the slab continuous casting machine, and has an important impact on the quality and efficiency of continuous casting production. The slab continuous casting roller is a roller used to support, guide and cool the cast billet in the continuous casting machine. It is a key component in the continuous casting production process. The design of the roller assembly structure needs to consider many factors, including the roller's strength, rigidity, heat load bearing capacity, ease of disassembly and assembly, etc. The roller needs to withstand the weight of the cast billet, billet pulling force, bulging force and other forces, so it must have sufficient strength and rigidity.
[0003] During the continuous casting process, the roller surface is always in direct contact with the red-hot steel billet and is subjected to a high thermal load. At the same time, due to the water spray cooling and roller rotation, this thermal load is alternating, which will cause serious thermal fatigue. At present, the roller is prone to defects such as roller surface scratches, bearing seat extrusion deformation, and mandrel bending during the production process. At the same time, it is not easy to disassemble, and the repair is difficult and expensive. Utility Model Content
