Cold rolled titanium plate treatment process
Hot Rolled Titanium Roll - Preparation Unit - Returning Unit - Shot Blasting Unit - Cold Rolling (Sengmir Mill) - Electrolytic Degreasing Unit - Vacuum Annealing - Flattening Unit - Straightening Unit - (Shot Blasting Unit) - Crosscutting (Slitting) Unit - finished product. The same time as
Hot-rolled titanium rolls are prepared in the cold-rolling workshop by cutting the head, welding lead (trimming, and roll) and performing the surface defects of the titanium strip (if necessary, the unit is also used for cold rolling or Vacuum furnace annealing, the strip of the trimming or titanium strip surface defects in order to carry out the second cold rolling and subsequent processing of the process), followed by titanium coil in a continuous continuous annealing unit for softening treatment, the general annealing Temperature at 750 ℃, heating 7min, heat 3min, followed by air cooling. After the annealing of the titanium roll in the shot blasting unit, through the high-speed jet steel ball crushing and removal of titanium oxide surface on the surface to satisfy the cold-rolled raw materials requirements. Then by the twelfth roller reversing cold rolling mill for cold rolling, generally by 5 to 15 passes, rolling to the finished product specifications. The titanium strip is rolled through the electrolytic degreasing unit to remove the grease staying on the strip after rolling. After degreasing treatment, the titanium coil is annealed in a vacuum annealing furnace. Argon is used as the shielding gas to prevent the titanium belt In the process of annealing in the annealing process, in order to eliminate the strip after the yield of the yield platform and the corresponding improvement of the strip shape, titanium coil in the flat unit to give 1 to 3% extension, flattened after the titanium Unit, to further improve the shape of the board, to meet the requirements of the user board shape, the titanium coil, respectively, through the cross-cutting unit, slitting units to obtain a variety of finished products, the user requirements of the surface quality is particularly high products, After the grinding and polishing unit, to give the appropriate optimization. The ultimate board, volume finished by the artificial packaging after storage.
As the pure titanium metal is a very valuable material, in the cold rolling production process to minimize the loss of titanium metal to improve the yield of titanium metal, so the main production units on the use of lead to improve the titanium available Length, reduce the volume with the head, tail does not meet the thickness requirements of the amount of shear, the corresponding access to a higher yield
