<p>An object of the invention is to provide a cold rolling mill and a cold rolling method which are able to effectively carry out rolling lubrication and cooling and roll at a high speed and under high rolling pressure while maintaining a high surface quality. Rolling lubrication oil (12) is supplied from spray headers (10) for lubrication at an inlet side of a rolling material (1), cooling water (13) is supplied onto the surfaces of work rolls (2) at an exit side of the rolling material (1), and the cooling water (13) is prevented by partition plates (11a) or jackets (17) from being scattered and adhered to the rolling material (1). Further, the rolling lubrication oil (12) and cooling water (13) are collected by a pan (3), separated by a separation tank (4) and recirculated to be used again. <IMAGE></p> |
