<p>PURPOSE:To prevent the generation of herringbone and to obtain product excellent in shape characteristic in cold rolling of a hard metallic sheet of stainless steel, titanium, etc. CONSTITUTION:Rolls 1, 2 parts of which in contact with at least the end parts of width of a rolled stock are helically ground are used as work roll and shearing force F2 toward the end parts of width from the middle of width is made to act on the rolled stock in the forward region (the outlet side from the neutral point) of the rolled stock 3. The roll may be one which only both end parts of barrel are helically ground. And, only one roll of upper and lower rolls may be a helically ground roll. Because buckling at the time of rolling the metallic sheet is prevented by the outward shearing force in the width direction, usually, front tension that is imparted during rolling can be extremely reduced. Then, there is no possibility of breaking of a strip in rolling and there is no need for specially modifying the device.</p> |
