Laser texturing processing method on surface of roller

Abstract

The invention discloses a laser texturing processing method on the surface of a roller, comprising the following steps: leading the roller to rotate with uniform velocity along self axes; leading a laser texturing head to move with uniform velocity along the axial direction of the roller; and periodically transmitting laser beam to the surface of the roller and forming texturing spots on the surface of the roller. The method is characterized by leading focal light spots to randomly swing with low amplitude from left and right at a preset spiral line so as to produce the irregularly distributedtexturing spots on the surface of the roller. As the roller has no smooth straight line between the two rows of the texturing spots on the circumference of the surface of the roller, when rolling a steel plate, the roller and the steel plate can prevent from jointing at those parts, the iron slag grains can be absorbed by texturing concave holes crisscross distributed on the peripheral directionof the roller, scratch can not be produced on the length direction of the steel plate, and the iron slag grains can not fray and break the texturing spots, thereby greatly improving the rolling quality of the steel plate and the wearing resistance of the roller, and prolonging the service life of the roller.

Description

technical field [0001] The invention relates to a laser roughening treatment method for the surface of a roll. Background technique [0002] Cold-rolled steel sheets with special surface topography are widely used in manufacturing, especially in the automotive and home appliance industries. Textured cold-rolled thin steel sheets are rolled by rolls with textured surfaces, and the textured surface features have a great influence on the technological properties of deep drawing and coating of steel sheets. [0003] In order to improve the shape, deep drawability, elongation and coating performance of cold-rolled steel sheets, in the cold-rolled sheet production process, it is required to roughen the roll surface of the cold-rolled work rolls, and then roll them to meet the user's special requirements. The cold-rolled textured steel plate required by the process. [0004] Laser texturing is the use of high-energy pulsed laser beams to focus on the roll surface, using the high ...

The distribution of texturing points on the entire surface of roll 11 can be regarded as the distribution of texturing points on many parallel circumferential lines, but generally the position of texturing points on the axis of roll 11 is not controlled, so the distribution of texturing points a in the transverse direction Generally messy, such as figure 2 shown
