Since there will be more or less dust and impurities on the surface of the steel plates, they will be brought into the heat treatment furnace and attached to the furnace rollers, causing nodules and wax on the surface of the furnace rollers, which not only affects the service life of the furnace rollers, but also directly affects the surface quality of the subsequent steel plates. In particular, the furnace rollers of the continuous annealing unit are prone to carbon deposition on the roller surface, resulting in pitting, sand eyes and other defects on the plate surface, affecting the surface quality of the product. Frequent replacement of furnace rollers is costly. Summary of the invention

The vibration motor connected to the grinding block causes the contact surface between the roller surface and the grinding device to produce high-frequency linear vibration friction to remove the nodules and carbon deposits on the roller surface. After completion, the furnace roller motor is stopped and the cylinder is started.
