Annealing method for cold rolling titanium coil

Номер: CN0102021509A
Автор: Xiang Wuyuan, Liu Jiandong, Xie Jianyi, Xie Xin, Tan Jingli
Принадлежит:

The invention provides an annealing method for a cold rolling titanium coil, wherein, as the last link for the production of a titanium belt, the folded titanium belt continuously passes through a heat preservation area protected by an inert gas at the temperature of 680-750 DEG C, and the heat preservation time is 150-250 seconds. The application of the method eliminates the preheating technology in the existing annealing method, shortens the annealing time and improves the annealing efficiency; moreover, the cold rolling titanium belt prepared by the annealing method has a granularity of less than 10 microns, thereby solving the technical problem of the titanium belt prepared by the existing annealing technology that the granularity is over-large.
