2. Titanium plate production status

  Hot working state (R) Cold working state (Y) Annealing state (M)

3. Titanium plate manufacturing process

  Hot forging is a forging process performed above the recrystallization temperature of the metal.

  Hot rolling is a rolling process performed above the recrystallization temperature.

  Cold rolling is a rolling process in which the plastic deformation temperature 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 speed (usually slow cooling, sometimes controlled cooling).

  Pickling: Immerse the workpiece in an aqueous solution such as sulfuric acid to remove oxide and other films on the metal surface. It is a pre-treatment or intermediate treatment for electroplating, enamel, rolling and other processes.

4. Characteristics of titanium plates:

1. The oxide film on the surface of the titanium seed plate is equivalent to a good long-lasting wear-resistant hair separation agent. The use of titanium seed plate saves the separation agent, makes the plate peeling easy, and eliminates the pre-treatment process of the seed plate. The titanium seed plate The board is half lighter than the copper type board.

2. The service life of the titanium seed plate is more than three times that of the copper seed plate, and can reach 10 to 20 years depending on the operating conditions.

3. The electrolytic copper produced from titanium seed plates has a dense crystal structure, a flat and smooth surface, and is of excellent quality.

4. Since the titanium seed plate does not need to be coated with a separating agent, it can avoid contamination of the copper electrolyte.

5. Increase production capacity and reduce electrolytic copper production costs, thereby achieving better economic benefits.
