Method for producing pure titanium strip through cold rolling

The invention discloses a method for producing a pure titanium strip through cold rolling, comprising the steps of pickling, cold-rolling, degreasing and annealing hot-rolled titanium strips. The method is characterized by adopting a 1500mm 6-high reversing cold rolling mill to cold-roll the pickled hot-rolled titanium strips. The cold rolling method comprises the following steps: sending the pickled hot-rolled titanium strips to the 1500mm 6-high reversing cold rolling mill to be rolled in first rolling length, annealing the titanium strips rolled in first length; and resending the annealed titanium strips to the 1500mm 6-high reversing cold rolling mill to be rolled in second rolling length. Large-coil heavy titanium strips with thickness of 0.3-0.8mm can be obtained on the conventional 6-high reversing cold rolling mill unit through two rolling lengths; therefore, the method is simple in procedures, low in cost and easy to realize rolling and can meet the requirement of production without improving the rolling mill.
