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.
