Title: Method for cold rolling titanium sheet of small sheet crown
Inventor: IWAMOTO KATSUTOSHI
IPC: B21B3/00
Filed: 1992-09-22
Abstract: PURPOSE:To provide titanium sheet of small sheet crown by rolling a shape after rolling into center buckle shape of a specified sharpeness in the range of specified thickness at the time of cold rolling a hot rolled titanium plate. CONSTITUTION:At the time of cold rolling the hot rolled titanium plate, in the range of thickness of >=1.0mm, the shape after rolling is rolled into the center buckle shape of sharpness of 1-3%. In a 1st cold rolling, for example, the hot rolled titanium plate is rolled into 1.5mm thick and, in finish rolling, 0.6mm thick. The sharpness at the time of cold rolling is 1.7% at a 1st time, center buckle is corrected in annealing and pickling treatments and cold finish rolling is executed. Even in this case, center buckle rolling is executed for a plate of >=1.0mm thick and, as the result, very small value of sheet crown of 5mum is attained. In this way, sheet crown generated on a hot rolled stock can be reduced at the time of cold rolling.
