Description

Technical Field

[0001] This utility model relates to the field of rolling mill production technology, specifically a rolling mill grinding and polishing device. Background Technology

[0002] Rolls are crucial components of steel rolling mills, significantly impacting mill efficiency and rolled product quality. Rolls utilize the pressure generated by the rolling motion of one or more rolls to roll the workpiece, causing plastic deformation and achieving the desired design shape. Therefore, the quality of the rolls directly affects the surface quality of the rolled product and the mill's production rate. They primarily withstand dynamic and static loads during rolling, as well as wear and temperature variations. To improve surface smoothness during production, surface treatment using polishing equipment is typically employed.

[0003] In the prior art, during the grinding and polishing of rolls, it is not possible to directly clean the rolls after polishing. During the polishing process, contaminants such as polishing wax and grinding particles are generated. If they are not cleaned in time, it will increase the difficulty of subsequent cleaning. Therefore, this utility model proposes a roll grinding and polishing device to solve the above problems. Utility Model Content
