Abstract

PURPOSE:To make the contact length between a strip and work rolls long and to make stable rolling possible with the small diameter rolls by inclining the direction between the centers of the upper and lower work rolls in the advancing direction of the strip. CONSTITUTION:In multistages cold rolling mills, the direction (y), (y')between the centers of upper, lower work rolls OT, OB is inclined with deviation from the direction at a right angle to the advancing direction (x'), (x) of a strip (a). Further, the shearing stress by the component of force P2 at a right angle to the direction between the centers of the upper, lower work rolls of the press down force within the section of the rolling material between the work rolls during rolling other than the rolling stress by the press down force P1 in the direction of the centers between the upper, lower work rolls in the same way as in usual is applied to the material (a) under rolling. Hence, the material is plastically deformed effectively, and it is also subjected to the plastic deformation by the bending force P3 by the upper, lower work rolls, whereby the stable high press down rolling is made possible.
