Laser Texturing for Roll
1. Application of laser texturing for roll
In order to produce high-quality cold-rolled sheet, coated sheet, enterprises need to work roll surface texturing. The previous method of roll texturing is shot peening, but it is difficult to accurately control the morphology and roughness of the roll surface, in order to solve this problem, Xi'an amctech Co. Ltd. in 2010 successfully developed the semiconductor laser texturing roller technology and equipment, the technology has been successfully applied in the field of production.The semiconductor laser texturing technology can accurately control the morphology processing of roll surface roughness (PPI) and (Ra), the rolling production of laser textured steel with good stamping formability and paint brightness, the plastic deformation ability improved, significantly better than the same material light panel and shot peening wool panel. The laser texturing technology can make the material in the laser zone obtain supernormal hardness at the same time, and bring the super strength and toughening effect to the roller surface and prolong the service life of the roller. The laser roller is 2~3 times longer than the ordinary roller. In addition, laser texturing can also improve the performance of rolls. Because of the optimization of friction conditions, rolling is not easy to slip and adhesion, rolling speed can be increased by more than one time, the bonding phenomenon of sheet annealing is eliminated, and even the laser rolls can be used to realize asynchronous rolling.
High repetition rate laser pulse semiconductor laser texturing technology using special acousto-optic modulation via optical focusing system, uniform scanning on the roll surface, the melting interval stability of micro pits and bosses are formed on the roller surface, thus completing the uniform roll surface texturing. The device can realize the controllable irregular wool distribution technology by software, and achieve the rhomboid, rectangle and irregular distribution of texturing points, and greatly improve the uniformity of wool production.
A work roll used for a leveling machine. The surface of the steel sheet (steel strip) is finally formed to meet the requirements of the user's roughness value, the density value and other special surface structure and morphology. It is beneficial to extend the stamping effect of the steel plate (strip steel) in the reforming process, reduce the scratches on the stamping parts, ensure uniform deformation of the stamping parts, and reduce the stress and loss of the die. According to the needs of users, all kinds of automotive panels, appliance plate, light plate, plate, plate, anti fake Mint different surface texture plate, special pattern plate, laser matte in production (Laser Matte Steel).
It is used for surface treatment of strip steel before various coating or coating processes, so as to increase the bonding strength of coating layer, reduce the consumption of coating (coating), and effectively improve the surface finish and reflectivity and freshness (DOI value) of coating. According to the needs of the users, the production of bright plate, laser mirror panel (Laser Mirror Steel) and so on.
A working roll used for a cold rolling mill. It is beneficial to bite, rectify, side wave control, stable rolling and plate type control.
The work roll used for the final rack of the cold tandem mill or the sheet surface hairy treatment before the heat treatment of the single frame mill. It is beneficial to prevent the steel coil from adhesion in the heat treatment process.
