Abstract (en)
[origin: EP2626149A1] The present invention provides a device for rolling a metal sheet material including: a housing that accommodates roll chocks, includes a pair of first project blocks protruding inwardly and bearing a force in a rolling direction acting on a bottom work roll, and further includes a housing window that bears a force in the rolling direction acting on a top work roll; a first hydraulic cylinder provided to the pair of first project blocks and including a first piston rod that applies an increase-bending force to the top work roll; a second hydraulic cylinder provided to the pair of first project blocks and including a second piston rod that applies an increase-bending force to the bottom work roll; a third hydraulic cylinder provided to a top back up roll chock and including a third piston rod that applies a decrease-bending force to the top work roll, or brings the top work roll into contact with a top back up roll to generate a roll balance force; and, a fourth hydraulic cylinder including a fourth piston rod that applies a decrease-bending force to the bottom work roll.
