Laser texturing has low noise and no pollution. Experiments and existing manufacturers' practices have proved that it has reached the leading technical level in China in extending the life of rollers, increasing the rolling speed of plates, improving product quality, overcoming slippage and adhesion during rolling, improving plate shape and improving plate (strip) quality, such as ductility, deep drawing, high coating quality, coating firmness and corrosion resistance of thin strip steel. Laser texturing process: after the roller is polished by a grinder, it is textured on a YAG laser texturing machine. Textured roll can be directly used in rolling mill without other changes to the original rolling mill and process flow. Please refer to the Technical Reference Manual of LTS-200 Laser Texturing Equipment for specific operation steps. Application scope of laser texturing technology: LTS-200 laser texturing equipment can be applied to iron and steel, nonferrous metallurgy, special strip steel, cold-rolled sheet, aluminum foil, galvanized sheet, stainless steel strip, precision strip steel in printing and packaging industry, precision etching of large ceramic net roller, laser texturing strengthening of hot roller and wire roller, laser etching drag reduction of engine steel body, and strengthening of chrome coating on the inner wall of military barrel, etc. Especially in the production of 0.005- 1.000mm high-quality metal plate (strip), the effect is particularly remarkable. Main configuration of laser texturing equipment: LTS-200 laser texturing equipment is suitable for medium-sized cold-rolled steel plate plants and aluminum foil cold-rolled plants. This technology can be applied to all kinds of cold-rolled plate (strip) plants in iron and steel metallurgy industry, especially to produce all kinds of high-quality metal plates (strips) with 0.005- 1.000 mm, and the effect is particularly remarkable. 1, laser system: a, choose Nd:YAG-200 W CW laser, ceramic condenser cavity and high-quality Nd:YAG crystal, double lamp pumping and semiconductor reference light source to ensure better beam quality. B, choose a dual-channel stable output power supply, which is mainly composed of main power supply, trigger circuit, control circuit and protection circuit. With overcurrent, overload, temperature and other circuit protection. The maintenance is simple and convenient, and it can guarantee 24-hour continuous operation. C. imported q-switch modulator and driver. D, the optical path adopts multiple beam expanding system to ensure the coarsening of high-density points. 2. Texturing machine tool system: spindle frequency conversion speed regulation, X and Z direction servo motor speed regulation, microcomputer control, automatic and manual operation. 3. Control system: DSP embedded control system, which is simple to operate, stable and reliable, and can realize database management. The light emission control is disordered distribution, and square, diamond, straight line or irregular light spots can be punched on the working face, and the shape of the roll surface can be flexibly controlled. 4. Water cooling system: 5P variable frequency water cooler is selected, and the temperature control accuracy reaches +/-0. 1 degree, ensuring the stable operation of the system. 5. Safety system: The equipment adopts a fully enclosed optical path to ensure that the laser will not scatter and leak, thus ensuring personal safety. 6. Monitoring system: equipped with CCD coaxial camera amplification system, which is convenient for the operator to control the focal length and observe the effect of roughened surface.
