Description
Technical Field
[0001] The utility model relates to a cooling device, in particular to a device capable of cooling the surface of a rolling roll, belonging to the technical field of rolling roll cooling equipment. Background Art
[0002] In hot rolling production, the rolling roll is a consumable part that is repeatedly reground and reused. Only by regularly removing the fatigue layer on the roll body surface can its performance be ensured to be stable. However, under the rolling steel conditions, the rolling roll is in contact with the strip steel for a long time, resulting in the roll body temperature reaching above 60°C. At this time, grinding the rolling roll will not only cause the physical heat of the rolling roll to be unable to be released, but also increase the grinding heat. Continuing to operate under such circumstances, the rolling roll will accelerate wear. When the internal stress exceeds the yield strength limit of the rolling roll, cracks will occur in the rolling roll, leading to the fracture of the rolling roll and causing scrap steel accidents. In addition, it will also cause problems such as strip steel scratching, uneven thickness, and scale pressing-in. At the same time, the grinding curve will change with the change of the roll body temperature, and the dimensional accuracy cannot be effectively guaranteed. During rolling, problems such as waves, poor strip shape, and incorrect convexity will occur, seriously affecting the continuity of the rolling line and the stability of the strip steel quality. Therefore, it is necessary to cool the surface of the rolling roll. At present, the cooling of the rolling roll is completed manually. The staff holds a water pipe to sprinkle water on the surface of the rolling roll for cooling treatment. This method not only fails to cool comprehensively, resulting in insufficient cooling of the rolling roll, but also takes a long time, affecting the production progress, and increasing the labor intensity. Therefore, a cooling device is needed that can efficiently and comprehensively cool the surface of the rolling roll. Summary of the Utility Model
