Titanium forging manufacturing process:? In metal forging process recrystallization temperature or higher. Hot rolling:? Rolling process at a temperature above the recrystallization temperature. Cold rolled? Reply temperature plastic deformation temperature is lower than rolling process. Annealing: the metal is slowly heated to a temperature sufficient to keep time, and then cooled to a suitable speed (slow cooling typically is sometimes controlled cooling) the heat treatment process of a metal. Pickling: immersing the article such as an aqueous solution *, to remove an oxide film such as a metal surface. A pre-treatment or intermediate processing plating, enamel, rolling and other processes. ? 5. The characteristics of the titanium plate 1. The starting sheet is a surface of titanium oxide thin film is equivalent to a perishable good wear resistance with the hair separation agent, a titanium starting sheet saves the separating agent, so that the plate? Peel easily, eliminating the species plate pre-treatment process, the titanium species plates lighter than copper seed plate half. 2. titanium species plate life is three times more than the copper seed plates, copper crystal structure up to 10-20 years 3. Preparation of Titanium kinds of plates depending on the operating conditions of a dense, smooth surface, good quality. 4. Because titanium species sheet without smearing separating agent, and thus avoid contamination copper electrolyte. 5. increase capacity to reduce copper production costs, thus better economic benefits.
