The cast is wound into a coil and then subjected to cold rolling with a roll having a surface roughness (Ra) of 0.2-0.7 µm at a cold rolling reduction of 50-98%.
The stainless steel sheet is manufactured through a temper rolling process using a dull roll after a finish cold rolling process and a bright annealing process.

The prelubrication avoids the formation of many surface defects during cold rolling.
The thickness control unit (11) acts on the last rolling stage (4) of the cold-rolling line.
The composite members are formed by using a continuous roll pressing process or apparatus, or a consolidated cold press process.
At the cold rolling step, the tantalum material (1) after the second kneading and forging step is subjected to cold rolling.
Disclosed is a pure copper plate production method wherein post-hot-forging and post-hot-rolling cold forging and cold rolling, and subsequent heat processing are unnecessary.
