Runqia company has successfully developed a new fiber laser texturing technology in the world. In the fiber laser with this technology, the laser pulse is output in the form of pulse train, which completely solves the bottleneck of disordered texturing and macro uniformity. Runqia laser texturing equipment not only fundamentally solves the problems of low roughness and low efficiency of existing YAG laser texturing equipment in metal surface texturing, but also revolutionizes the integration of laser and machine tool, improves the stability and roughness uniformity of laser texturing equipment, and is also the only texturing solution comparable to EDM surface texturing technology.

Laser texturing technology uses high-energy and high repetition rate pulsed laser beam to irradiate the negative defocus on the roll surface after focusing to preheat and strengthen, and the focused focus is incident on the roll surface to form a micro molten pool. At the same time, the side blowing device applies auxiliary gas with set pressure and flow to the micro molten pool, Make the melt in the molten pool accumulate to the edge of the molten pool as much as possible according to the specified requirements to form an arc-shaped boss (peak number).

The small pits on the surface of laser textured steel plate are not connected, which is conducive to storing oil and capturing metal debris during later stamping forming. It has good oil storage, prevents stamping scratch and ensures the deep drawing of steel plate. And make the surface of stamping parts smooth, and reduce the stamping oil at the same time.

The laser texturing morphology of the roll surface is uniform and controllable, and the smooth surface accounts for 60% of the whole textured surface, so that the flatness of the rolled steel plate is high, and the smoothness of the strip surface and the freshness after painting are improved. It increases the competitiveness of products for users and can produce laser mirror steel.

·The disordered texturing process is mature: through the core pulse train laser output, the disorder of each laser texturing point can be realized. Combined with the texturing process, the texturing effect can be developed according to the requirements of different RA / RPC values.

·High processing efficiency: the pulse frequency of laser texturing equipment is up to 100kHz, and its processing efficiency is much higher than that of traditional acoustooptic modulation YAG laser texturing equipment, which can meet the production requirements of the factory.

·High adjustable range of roughness: under the condition of high efficiency processing, the roughness parameters can be changed by directly controlling the laser power, and the Ra value can be up to 0.5 ~ 20 μ M adjustable.
