Defect control method of roller and edge plate profile of strip steel

A defect control method of rollers and the edge plate profile of strip steels comprises the following steps of: 1) preparing rolling on a rolling mill after grinding a plurality of rollers; 2) pulling the rollers away from the rolling mill after normal rolling according to the rolling plan; 3) sending messages of the rollers when pulling the rollers away from the rolling mill; 4) collecting the rolling data of this time; 5) calculating the collected rolling data to determine the wear conditions after pulling the rollers away from the rolling mill ; 6) performing appropriate air-cooled or water-cooled operation to reduce the temperature of the roller to the room temperature; 7) calculating the width, thickness, hardness and temperature of next rolling plan and determining main rolling material; 8) selecting corresponding rollers meeting the requirements for preparing rolling according to real roller data in a database; 9) using the rollers on the rolling mill; and 10) pulling the rollers on and away from the rolling mill for 5 to 8 times according to the steps from 2) to 9). By using the method, the defects of the roller and the edge plate profile of the strip steel can be controlled when in the rolling of the strip steels.
