Titanium Plate Manufacturing Processes

Hot Forging
It is a forging process carried out above the metal's recrystallization temperature. The purpose is to shape the titanium material through plastic deformation at high temperatures. This process can break the original coarse - grained structure of the titanium, refine the grains, and improve the mechanical properties of the material such as its density and strength.

Hot Rolling
This is a rolling process that occurs above the recrystallization temperature. The titanium billet is heated to a temperature higher than the recrystallization temperature and then passed through a series of rollers. The rollers gradually reduce the thickness of the material and change its shape into a plate. Hot rolling can significantly reduce the thickness of the titanium and improve its plasticity, making it more suitable for subsequent processing.

Cold Rolling
It is a rolling process in which the plastic deformation temperature is lower than the recovery temperature. Cold - rolled titanium plates have a more accurate thickness and better surface smoothness. Through cold rolling, the mechanical properties of the titanium plate can also be adjusted to a certain extent. For example, its hardness can be increased while maintaining a certain level of ductility.

Annealing
It is a metal heat - treatment process in which the metal is slowly heated to a certain temperature, held for a sufficient period of time, and then cooled at an appropriate speed (usually slow cooling, sometimes controlled cooling). For titanium plates, annealing can relieve the internal stress generated during the previous forging or rolling processes. It also helps to improve the mechanical properties and dimensional stability of the titanium plate, making the material more uniform in structure and performance.

Pickling
This process involves immersing the workpiece in an aqueous solution such as sulfuric acid to remove oxide films and other substances on the metal surface. It is a pretreatment or intermediate treatment for processes such as electroplating, enameling, and rolling. By removing the oxide film, it can improve the surface quality of the titanium plate and provide a better base for subsequent surface - treatment or further processing steps.
