Embodiment 1
[0015] A kind of production method of cold-rolled titanium-steel clad plate is carried out according to the following process steps:
[0016] (1) Assemble the titanium plate and steel plate to form a steel plate-transition layer-titanium plate-separator-titanium plate-transition layer-steel plate symmetrical multi-layer combination blank;
[0017] (2) Roll the combined billet with a hot rolling mill. The rolling conditions are: heating temperature: 900°C, heating time: 16 minutes per centimeter of billet thickness, starting rolling temperature: 800°C, final rolling temperature: 700°C , coiling temperature: 650°C;
[0018] (3) Uncoil after rolling, and divide into two single-sided composite rolls;
[0019] (4) Anneal at 900°C in a continuous bright annealing furnace with electricity as the heat source, and then pickle at room temperature after naturally cooling to room temperature. After pickling, roll with a cold rolling mill to obtain the required titanium-steel composite pl...

[0027] A kind of production method of cold-rolled titanium-steel clad plate is carried out according to the following process steps:
[0028] (1) Assemble the titanium plate and steel plate to form a steel plate-transition layer-titanium plate-separator-titanium plate-transition layer-steel plate symmetrical multi-layer combination blank;
[0029] (2) Roll the combined billet with a hot rolling mill; the rolling conditions are: heating temperature: 940°C, heating time: 20 minutes per centimeter of billet thickness, starting rolling temperature: 850°C, final rolling temperature: 800°C, Coiling temperature: 680°C;
[0030] (3) Uncoil after rolling, and divide into two single-sided composite rolls;
[0031] (4) Anneal at 1050°C in a continuous bright annealing furnace using electricity as the heat source, and then pickle at room temperature after naturally cooling to room temperature. After pickling, roll with a cold rolling mill to obtain the required titanium-steel composite p...
