A method of roughening and marking patterns on roll surfaces

Abstract

The invention discloses a method for texturing and pattern marking of the surface of a roller. The method comprises the steps: acquiring a mark pattern, and setting texturing main shaft speed, texturing point spacing, a texturing start point, a texturing end point, texturing frequency, texturing duty ratio, marking main shaft speed, marking point spacing, a marking start point and a marking end point; measuring to obtain the diameter of the roller; during the texturing of the roller, starting a main shaft according to the texturing main shaft speed, controlling a texturing and marking head to move to the texturing start point, and emitting a texturing laser beam to the surface of the roller according to the texturing point spacing till the texturing end point; during the marking of the roller, starting a main shaft according to the marking main shaft speed, controlling the texturing and marking head to move to the marking start point, and emitting a marking laser beam to the surface of the roller according to the marking point spacing till the marking end point, so as to enable the mark pattern to emerge from the surface of the roller. According to the method, the integration of texturing and pattern marking is realized, and the rollers, of which roll surfaces have customer required patterns, such as company LOG or anti-counterfeiting marks, can be produced.

Description

technical field [0001] The present application relates to the field of steel rolling, in particular to a method for laser roughening and marking the surface of a roll. Background technique [0002] In the production of cold-rolled steel sheets, it is found that a series of morphology parameters of cold-rolled sheets have an important impact on the stampability, elongation, and coating adhesion of steel sheets and other process properties. The surface morphology of the cold-rolled sheet depends to a large extent on the surface morphology of the work rolls in the cold-rolled production process. This creates a requirement for roughening the roll surface. In addition, due to the requirements of the plate cold rolling process, the surface of the roll needs to be provided with a certain roughness to ensure that the roll has a certain friction during the rolling process. In addition, in order to prevent the thinner plate from sticking during bell annealing, it is also necessary t...
