Abstract

[0002] In the field of hot rolling production, rollers are extremely important production equipment, which can control the plate shape. Through the optimized design of rollers, the flow behavior of metal in the rolling process can be controlled, and the local uneven extension of the strip can be reduced, so as to obtain a better plate shape. As time goes by, the surface of the roller will wear due to friction, and the unevenness will affect the quality of subsequent rolled products. Therefore, it is necessary to regularly inspect the surface of the roller to ensure that its surface uniformity meets the standard to avoid affecting the subsequent rolling operation. At present, the inspection of the roller surface is carried out manually using an outside diameter micrometer. This point-to-point inspection method not only has large errors, but also has extremely low efficiency and high labor intensity, and cannot fully inspect the roller. Therefore, a roller profile detection device is needed, which is required to be able to efficiently detect the roller surface, reduce the labor intensity of the staff, and improve the roller inspection efficiency.
