In the process of rolling and cooling the cold-rolled strip steel, oxides are often generated on the surface of the strip steel for various reasons to influence the quality of the strip steel, and therefore, in order to eliminate the oxides, the cold-rolled strip steel needs to be pickled on an acid pickling line. The strip steel is subjected to multiple actions of staggered withdrawal and straightening rollers in an acid rolling mill, so that oxides existing on the original surface are removed through acid washing. Therefore, the function of the withdrawal and straightening rollers directly influences the product quality of the plate strip.
In the actual production process, because the uneven temperature field in the work environment of the tension leveler generates stress, the temperature field is periodically changed along with the rotation of the roller, the stress is also changed along with the rotation of the roller, the roller surface is higher in temperature, the fatigue strength is reduced, thereby the surface of the roller is cracked due to fatigue, meanwhile, the tension leveler is subjected to the action of mechanical stress when the plate belt is pickled, the roller surface is severely worn, the quality of the plate belt is influenced, the service life of the tension leveler is also severely influenced, and the service life of the tension leveler in the original state is 5-7 days. The current solution is: the wear-resistant material is deposited on the roller surface to improve the wear resistance of the roller surface, so that the service life of the roller is prolonged, but the method is high in cost, the problems of roller surface wear, cracking and the like cannot be well solved, and the welding layer is easy to peel off. In conclusion, the existing acid rolling mill withdrawal and straightening roller has the defects of poor product quality, high production cost, short service life and the like.
