Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a roller structure for metal processing. Background Art

[0002] Rollers in metal processing are a key industrial component that plays a vital role in various rolling processes. Rollers are round, roll-shaped parts that are usually made of high-strength steel and are precision machined and heat-treated to have excellent wear resistance and impact resistance. Rollers are in direct contact with the metal surface during the rolling process, exerting pressure on it to produce the desired shape and size of the metal. In this process, the rolls are subjected to strong friction and high temperatures, so they must have high hardness and good thermal stability to ensure the stability of production and the quality of metal products. The manufacture of rolls requires multiple processes. First, the appropriate material is selected, usually high-carbon steel or alloy steel, to ensure that the rolls have sufficient strength and wear resistance. Then, the rolls are processed into the desired shape and size through precision machining techniques such as turning and grinding. After machining, heat treatment is performed to enhance the hardness and corrosion resistance of the rolls. There are many types of rolls according to different application scenarios. For example, rolls used for cold rolling need to withstand greater pressure and friction, so they have larger diameters and harder surfaces.

[0003] In metal processing, the quality of the rolls directly affects the quality of the products and the stability of production. Therefore, in order to ensure the performance and life of the rolls, regular inspection and maintenance are required, and severely worn rolls should be replaced in time to ensure smooth production. However, the existing rolls are generally installed on the rolling mill frame through multiple bolts and other fasteners.
