Cold rolled titanium plate production process

2025 07/24

Cold-rolled titanium plates use hot-rolled titanium pipes as raw materials. After pickling to remove oxide scale, they are cold-rolled. The products after cold rolling are hard rolled coils. Due to cold work hardening caused by continuous cold deformation, the strength and hardness of hard rolled coils increase, while the toughness and plasticity index decreases. Therefore, the stamping performance will deteriorate and can only be used for parts with simple deformation.

Hard rolled coils can be used as raw materials in hot-dip galvanizing plants because hot-dip galvanizing units are usually equipped with annealing lines. The coil weight of cold-rolled titanium plates is generally between 6 and 13.5 tons, and the inner diameter of titanium tubes is 610mm. In order to improve the performance of cold-rolled titanium plates, continuous annealing (CAPL unit) or bell furnace annealing is usually required to eliminate cold work hardening and rolling stress and achieve the mechanical performance indicators specified in the corresponding specifications.

The surface quality, appearance and dimensional accuracy of cold-rolled titanium plates are better than those of hot-rolled plates, and their thickness can be rolled to about 0.18mm, so they are very popular among users. Using cold-rolled titanium pipes as the substrate for deep processing, high value-added products can be made, such as electro-galvanized, hot-dip galvanized, fingerprint-resistant electro-galvanized, color-coated titanium coils, vibration-damping composite titanium plates, PVC laminated titanium plates, etc. These products have excellent qualities such as aesthetic appearance and high corrosion resistance, and are widely used.

Finishing treatment

After annealing, cold-rolled titanium tubes need to be finished, including head, tail, edge trimming, leveling, flattening, rewinding or longitudinal shearing, etc. These treatments can further improve the dimensional accuracy and surface quality of titanium plates to meet the different needs of users.

Application areas

Hot-rolled and cold-rolled titanium plates are widely used in automobile manufacturing, home appliances, instrument switches, construction, work furniture and other industries. The weight of each package of titanium plates after packaging is 3~5 tons, and the flat roll weight is usually 3~10 tons/roll.

To sum up, the production process of titanium plates includes hot rolling, cold rolling and subsequent finishing treatment. Each link has its specific process requirements and quality control standards to ensure that the quality and performance of the final product meet user needs.
