The surface defects of titanium plate are divided into conventional and non conventional defects. First, we tell you the conventional defect:
1. Scratch
Reasons: the guide board, roller, tools are not clear, and there are adhesive or sharp burrs etc., or the rolling scratch the surface. What's more, the careless operation may cause the collision with each other, and then form the scratched surface.
Measures: to check the tool, the guide plate, roller and roller etc. before rolling. If you found problems, you should remove it timely. In addition, operation must be careful, don't pull or bump disorderly.
2. Metal materials being pressed into machine
Reasons: the metal materials are pressed on the surface of the product because of the workpiece edge burr and tail dregs.
Measures: the slab edge burr and surface foreign bodies should be timely eliminated. The crack edge and crack head should be cut off timely.
3. Non- metal materials being pressed into machine
Reasons: poor environmental sanitation, dust falls on the workpiece surface, and it can't be cleaned after the acid pickling.
Measures: Do the health very well, and the workpiece surface adhesion should be timely removed.
4. Pockmark
Reasons: During the pressure correction annealing, there is dust on the surface of platen or backing plate.
Measures: The surface of platen or backing plate should be removed timely before entering furnace.
5. Roll mark
Reasons: the surface wear of roller is serious, and there are pits, pitting surface, scratches and other reasons. The pits are pressed by the plate angle on the surface of the roller.
Measures: Once find roller mark, grinding or replacement roller.
The following are non conventional defects:
1. Table bifida
Reason: The incoming materials are non-conforming, the surface crack is not clean or the surface brittleness suction layer of incoming materials is not cleared. In addition, the reduction schedule is not reasonable, the working rate of pass is small, pass is too much, or the processing rate of pass is unequal distribution.
Measures: the incoming material surface quality should be strictly controlled, the working rate of pass should be distributed reasonable, uniform slab annealing temperature should be ensured and the rolling lubrication should be enhanced.
2. Acid spot
Reasons: the residual acid is not clean during the pickling, the plate materials is formed by drying. In addition, the plate materials in the stacked annealing, the surface oxidation is not uniform, and surface corrosion degree is not uniform after pickling.
Measures: the pickling must be clean, ensure the plate surface without residual acid, and then drying; reduce the stacking thickness of plate, ensure the uniform annealing; What's more, you can also use the sanding treatment as the late saving treatment.
Titanium plate can be applied to be implanted into the human body. Titanium plate can be used in surgical operation instrument, pacemakers and centrifuge.
