The roller mainly comprises a roller body, a roller neck and a shaft head part. The roller body is the middle part of the roller actually participating in the rolling of metal, which has a smooth cylindrical surface or a surface with rolling grooves. The roller will generate heat due to friction during use, and the generated heat will have a great impact on the quality of the roller and the workpiece.

The beneficial effects are that the cooling water circulating in the roller body is filtered by the filter box, reducing the generation of scale. The scale in the roller body is scraped by the scraper and washed by the water sprayed by the spray head, so that the scale in the roller body falls off, avoiding the accumulation of scale in the roller body, ensuring the normal heat exchange of the roller body, facilitating the cleaning of the roller body in the later period, and avoiding the influence of scale accumulation on the cooling of the roller body.
