Problems solved by technology

However, the controllable distribution of texturing adopts single beam (or electron beam) texturing, and its texturing speed is not as fast as that of shot peening and electric spark texturing (often using multiple pairs of electrode discharges).

Embodiment Construction

[0025] Such as figure 1 As shown, a texturing device for high repetition frequency pulse laser-induced electrode directional discharge on the surface of a roll, the device includes a pulse power supply 1, a high repetition frequency pulse laser generator 2, a discharge electrode 3, a control device 4 and a roll to be processed 5, Roll clamping mechanism 6;

[0026] The pulse power supply 1 is a fast charging and discharging power supply, the negative electrode is connected to the discharge electrode 3, and the positive electrode is connected to the roll 5 to be processed. There is a distance not greater than 1 mm between the discharge electrode 3 and the roll 5 to be processed. The gap is filled with air. The breakdown voltage between the rolls 5 to be processed is above 3000 volts, and the pulse inter-electrode voltage of the pulse power supply 1 is up to 500 volts, so as to ensure that there will be no automatic breakdown discharge between the discharge electrodes 3 and the ...

Description

technical field [0001] The invention relates to a surface processing equipment for metal materials. Background technique [0002] The surface of high-quality cold-rolled thin steel sheet requires a certain roughness profile to improve the formability and coating performance of the steel sheet. To produce high-quality cold-rolled sheets, the surface of the work rolls of the rolling mill must first be textured and shaped, and then the rolling mill uses the textured rolls to roll a cold-rolled textured sheet with the required roughness and shape. At present, the texturing technology of rolls includes shot peening (SBT), electric spark texturing (EDT), laser texturing (LT) and electron beam texturing (EBT). Steel grit is sprayed onto the surface of the roll at high speed, relying on the kinetic energy impact of the steel grit to plastically deform the surface of the roll to change the surface morphology; EDM texturing uses multiple pairs of electrodes to discharge and melt the ...
