Abstract
A cold roll laser texturing method relates to a method for carrying out laser texturing on a cold roll and aims to solve problems of short service life, short roll replacement period, high cost, and the like, which exist in present laser texturing technologies. The method comprises the following steps: firstly parameters are determined, wherein, input power of a laser ranges from 2KW to 7KW, optical pulse power ranges from 32W to 45W, spot size ranges from 60 microns to 100 microns, dot pitch ranges from 100 microns to 150 microns, thread pitch ranges from 80 microns to 100 microns, optical pulse width ranges from 2mus to 10mus, the rate of randomness ranges from 60 percent to 80 percent, the density of distribution ranges from 50 dots/mm<2> to 70 dots/mm<2>, and texturing roughness ranges from 0.7 micron to 1.5 microns; and secondly, the laser texturing for the surface of the cold roll is carried out according to the parameters determined in the first step.
Description
Technical field
The present invention relates to a kind of roughing method of cold roll.
Background technology
As everyone knows, the surface of steel plate all will be handled through texturing, and they form by the texturing roll compaction.The roller surface texturing is to adopt sandblast to form surface texturing the earliest.Spark technology has appearred in the 70-80 age, forms the texturing hole with discharge at roller surface.Developed laser technology about the nineties again, laser beam has been focused on roller surface carry out roller texturing.This technology is called the texturing technology of the third generation.It utilizes the pulsed laser action of high energy, high frequency at roller surface, make it heating, fusing and partial gasification, in the molten bath that forms under the effect of fluid level gauge surface tension and assist gas, the partial melting metal is pushed to melt tank edge, because the fast cold characteristic of the fast heat of laser, this part metals is solidified rapidly at melt tank edge, forms projection, forms dimple structure simultaneously in the middle of the molten bath.
But people are when utilizing the laser roughening technology that cold roll is handled at present, because each parameter is provided with the bad of cooperation, make the surface uniformity of rolling inferior light aluminium sheet, foil bad, the not good situations of combination property such as differential big, the deep drawability difference of percentage elongation, afterwards influence the service life of roll, the roll change cycle is short, and the cost height.
Summary of the invention
The present invention makes the service life of cold roll low in order to solve existing laser roughening technology, and the roll change cycle is short, and problem such as cost height, and a kind of cold roll laser texturing method is provided.
The step that realizes the inventive method comprises:
Step 1: setup parameter, the laser instrument input power is between 2KW to 7KW, light pulse power is between 32W to 45W, spot size is between 60 μ m to 100 μ m, point is apart between 100 μ m to 150 μ m, and pitch is between 80 μ m to 100 μ m, and the light pulsewidth is between 2 μ s to 10 μ s, random rates is between 60% to 80%, and distribution density is at 50 points/mm
2To 70 points/mm
2, the texturing roughness is at 0.7 μ m to 1.5 μ m;
Step 2: the laser instrument of a described setup parameter produces the pulse laser beam of high-repetition-rate set by step, described laser beam focuses on through lens combination and exposes to the cold roll surface of being the uniform speed rotation, produce the high temperature molten bath in cold roll surface local position, the assist gas of pressure of composition, setting that is aided with setting simultaneously is along the metal melt in the angle side-blowing bath of setting, make it by specifying requirement to be stacked into melt tank edge, and cooling forms the concavo-convex little hole of sclerosis, surface rapidly, realizes the laser roughening on cold roll surface.
Advantage of the present invention: by carrying out cold roll laser texturing after the parameter setting of the present invention, the inferior light aluminium sheet that makes, the surface uniformity of foil obviously improve, percentage elongation is differential to be reduced, deep drawability increases, material surface has excellent comprehensive performances, has improved the service life of roll, the roll change cycle of prolongation, improve productivity, effectively saved cost.
