Causes and Control of Surface Defects of Cold Rolled Titanium Plate

Titanium and titanium alloy is an extremely important lightweight structural materials, widely used in aerospace, vehicle engineering, biomedical and other fields, have always been a hot material research. With the development of economy and technology, there have been more and more applications of titanium plate, but the corresponding surface quality problems are more prominent.

Titanium plate surface defects are conventional weaknesses and unconventional defects two categories. The general defect is:

1, scratches

Reason: guide plate, roller table, tools and roll is not clean, there are stickers or angular burrs, rolling scratch surface; operation is not careful, so that the collision to form a scratch surface.

Measures: before rolling to check the tools, guides, roller and roll, etc., found that the problem in time to clear; operation carefully, does not pull chaos hit.

2, metal presses

Cause: the edge of the rolling burr and tail dregs pressed into the product surface.

Measures: timely elimination of burr edge glitches and surface foreign body. Crack edge, split in time to cut off.

3, non-metallic presses

Reason: poor sanitation, dust and foreign matter fall on the surface of the workpiece; after pickling, cleaning is not unadulterated.

Measures: do a good job of health, judicious removal of surface adhesion of the workpiece.
