Abstract

The invention relates to a roughening processing method for the surface of a roller. The roughening processing method for the surface of the roller comprises the steps that the roller carries out constant-speed rotation around the axis of the roller, laser roughening heads carry out constant-speed motion in the axial direction of the roller, and laser beams are emitted to the surface of the roller in a timed mode to form roughening points on the surface of the roller; the roughening points are distributed on the surface of the roller along large-dip-angle spiral lines by increasing the motion speed, in the axial direction of the roller, of the laser roughening heads, and the thread pitch of the large-dip-angle spiral lines ranges from 10mm to 200mm. According to the roller manufactured through the roughening processing method for the surface of the roller, smooth straight lines do not exist between every two adjacent rows of roughening points on the circumference of the surface of the roller, attachment any longer, at the positions between every two adjacent rows of roughening points, between the roller and a steel plate can be avoided, produced scrap iron particles can be easily contained by roughening pits which are formed in a staggered mode in the circumferential direction of the roller, scratches cannot be caused in the length direction of the steel plate any longer, abrasion and damage caused by the scrap iron particles to the roughening points cannot exist, the rolling quality of the steel plate is greatly improved, and abrasion resistance of the roller is greatly improved.

Description

A kind of roller surface texturing processing method

Technical field

The present invention relates to a kind of roller surface texturing processing method.

Background technology

The cold-reduced sheet with special surface pattern has a wide range of applications in manufacturing industry, particularly in automobile and electrical appliance industry.Texturing cold-reduced sheet is that the roll rolling of being processed through texturing by surface forms, and the surface appearance feature of its texturing on processing performance impacts such as the deep-draw of steel plate, applications greatly.In order to improve template, deep drawing quality, percentage elongation and the coating performance of cold-reduced sheet, in flat cold-rolled sheet production technology, require the roll surface of cold roll to carry out texturing processing, then roll out the cold rolling textured steel sheet that meets the requirement of user's special process.

Summary of the invention

For problems of the prior art, the object of the present invention is to provide a kind of technical scheme of roller surface texturing processing method.

Described a kind of roller surface texturing processing method, is characterized in that: each components based on weight percentage of this roll is: C:0.85%-1.10%; Si:0.6%-1.0%; Mn:0.20%-0.8%; Cr:5.5%-7.5%; Mo:0.30%-0.8%; V:0.1%-0.3%; Ni≤0.4%; P≤0.020%; S≤0.015%; All the other are Fe and inevitable impurity; The texturing processing method of this roll is: first make roll at the uniform velocity rotate along self axis, make laser roughening head along the axial uniform motion of roll simultaneously, and regularly to the surface-emitting laser bundle of roll, on the surface of roll, form texturing point; By accelerate laser roughening head along roll mandrel to movement velocity, texturing point is distributed rolling the high inclination-angle helix of rod surface along pitch 10mm-200mm.

Described a kind of roller surface texturing processing method, it is characterized in that described laser roughening head along roll mandrel to movement velocity be 10-200m/min.

Described a kind of roller surface texturing processing method, is characterized in that the pitch of described high inclination-angle helix is 50-180mm.

Described a kind of roller surface texturing processing method, is characterized in that the pitch of described high inclination-angle helix is 100-150mm.

The roll of making by the inventive method, owing to no longer including level and smooth straight line between adjacent 2 row's texturing points on its surperficial circumference, therefore in rolled plate, can avoid roll and steel plate in the laminating at these positions, the iron filings particle producing can be absorbed by staggered texturing pit in roll circumference direction easily, can on the length direction of steel plate, not cause cut again, can not make iron filings particle that texturing point is caused wearing and tearing and destroyed yet, thereby both greatly improved steel plate rolling quality, greatly improved again the wearability of roll self, extended the service life of roll.

The roll of making by the inventive method is in addition owing to no longer occurring indistinct " straight line " texturing pattern at length direction, therefore can avoid laterally shutting out regular straight line lines at steel plate in rolled plate, thereby greatly improve the presentation quality of steel plate.

The specific embodiment

Roller surface texturing processing method of the present invention, each components based on weight percentage of this roll is: C:0.85%-1.10%; Si:0.6%-1.0%; Mn:0.20%-0.8%; Cr:5.5%-7.5%; Mo:0.30%-0.8%; V:0.1%-0.3%; Ni≤0.4%; P≤0.020%; S≤0.015%; All the other are Fe and inevitable impurity; The texturing processing method of this roll is: first make roll at the uniform velocity rotate along self axis, make laser roughening head along the axial uniform motion of roll simultaneously, and regularly to the surface-emitting laser bundle of roll, on the surface of roll, form texturing point; By accelerate laser roughening head along roll mandrel to movement velocity, texturing point is distributed rolling the high inclination-angle helix of rod surface along pitch 10mm-200mm.

Above-mentioned laser roughening head along roll mandrel to movement velocity be 10-200m/min, the pitch of high inclination-angle helix is 50-180mm, is preferably 100-150mm.
