Titanium plate manufacturing process：
Hot forging is a forging process carried out above the recrystallization temperature of metal.
Hot rolling is a rolling process that is carried out above the recrystallization temperature.
The plastic deformation temperature of cold rolling is lower than the recovery temperature.
Annealing: a metal heat treatment process in which the metal is slowly heated to a certain temperature, maintained for a sufficient time, and then cooled at an appropriate rate (usually slow cooling, sometimes controlled cooling).
Pickling: immerse the parts in the aqueous solution of sulfuric acid to remove the oxide film on the metal surface. It is the pretreatment or intermediate treatment of electroplating, enamel, rolling and other processes.
Characteristics of titanium plate:
1. Titanium seed plate is a kind of oxidation film on the surface, which is equivalent to a kind of good durable and wear-resistant hair separator. The use of titanium seed plate saves the separator, makes the stripping of electrode plate easy, and avoids the pretreatment process of seed plate. Titanium seed plate is half lighter than copper seed plate.
2. The service life of titanium seed plate is more than three times that of copper seed plate, and it can reach 10 to 20 years according to the operating conditions
3. The electrolytic copper made from titanium seed plate has compact crystal structure, smooth surface and excellent quality.
4. Because the titanium seed plate does not need to be coated with separating agent, the pollution of copper electrolyte can be avoided.
5. Improve the production capacity and reduce the production cost of electrolytic copper, so as to have better economic benefits.
