[0002] A rolling mill is a device that realizes the metal rolling process. It generally refers to the equipment that completes the entire process of rolled material production. According to the number of rollers, rolling mills can be divided into two-roller, four-roller, six-roller, eight-roller, twelve-roller, eighteen-roller, etc.; according to the arrangement of the rollers, they can be divided into "L" type, "T" type, "F" type, "Z" type and "S" type.

[0003] The existing rolling mill cools the roller body by spraying water on the roller during use. Since the above method only cools the roller surface, a large amount of heat will accumulate in the roller body and cannot be discharged, which will still cause the roller body temperature to be high, resulting in poor cooling effect on the roller body and affecting the subsequent use performance of the roller body. Therefore, a rolling mill main body structure that is conducive to roller cooling is urgently needed to solve the above problem. Utility Model Content
