Abstract
The invention discloses a cold rolling technology for titanium plates. The technology comprises the steps that a titanium belt is rolled in a horizontal continuous annealing unit for softening processing, the annealing temperature is 720 DEG C, the heating time is 7 min, the heat preservation time is 3 min, and then air cooling is carried out; the annealed titanium roll is broken through high-speed jetting steel shots in a shot blasting unit, and an oxide layer on the surface of the titanium belt is removed; a twelve-roller reversing cold mill is adopted for cold rolling, conducting rolling by 10-15 passes to obtain finished products; the rolled titanium belt roll passes through an electrolytic degreasing unit, and grease remaining on belt materials after rolling is carried out is removed. Due to the fact that the titanium belt roll is softened, the plasticity of the titanium belt roll is improved, follow-up cold rolling forming is ensured, cracks are prevented from occurring in the cold machining process, and the rebound rate obtained after cold rolling forming is carried out is low.
Description
Technical field
The invention belongs to titanium plate processing technique field, be specifically related to a kind of cold-rolling process of titanium plate.
Background technology
Titanium has good corrosion resistance, not by air and extra large water mitigation, is applied to ocean development field, has the good reputation of " marine metal ", though China is the big country that titanium material is produced, but the production technology of Thin Specs titanium band is ripe not enough.
Summary of the invention
In order to overcome the above-mentioned technical problem that prior art field exists, the object of the invention is to, provide a kind of cold-rolling process of titanium plate, Crack prevention produces, and lumber recovery is high.
The cold-rolling process of titanium plate provided by the invention, comprises the following steps: titanium strip coil is carried out sofening treatment by (1) in horizontal continuous annealing unit, and annealing temperature is 720 DEG C, heating 7min, insulation 3min, subsequently air cooling; (2) titanium after annealing twists in ball blast unit, smashes and remove the oxide layer on titanium belt surface by high velocity jet shot; (3) adopt twelve-roller reversible cold-rolling mill to carry out cold rolling, through 10 ~ 15 passes, be rolled into finished product; (4) roll rear titanium strip coil through electrolytic degreasing unit, to remove after rolling remain in grease on band.
The cold-rolling process of titanium plate provided by the invention, its beneficial effect is, carries out sofening treatment to titanium strip coil, and improve the plasticity of titanium strip coil, guarantee follow-up cold roll forming, avoid occurring crackle in cold worked process, after cold roll forming, rebound degree is low.
Detailed description of the invention
Below in conjunction with an embodiment, the cold-rolling process of titanium plate provided by the invention is described in detail.
Embodiment
The cold-rolling process of the titanium plate of the present embodiment, comprises the following steps: titanium strip coil is carried out sofening treatment by (1) in horizontal continuous annealing unit, and annealing temperature is 720 DEG C, heating 7min, insulation 3min, subsequently air cooling; (2) titanium after annealing twists in ball blast unit, smashes and remove the oxide layer on titanium belt surface by high velocity jet shot; (3) adopt twelve-roller reversible cold-rolling mill to carry out cold rolling, through 10 passes, be rolled into finished product; (4) roll rear titanium strip coil through electrolytic degreasing unit, to remove after rolling remain in grease on band.
Claims (1)
