Abstract
It is found that a deformation zone with two neutral sections can exist in a strip during cold rolling in certain working stands in continuous rolling mills. A second neutral section appears in the region of elastic recovery of part of the strip thickness at the end of the rolls. A reliable procedure has been developed to identify the type of deformation zone; it can determine the number of neutral sections in the deformation zone of each working stand in a rolling mill. A method for the calculation of the contact stresses, forward-creep coefficient, and rolling force in the deformation zone with two neutral sections is described. The application of this method decreases the error of force calculation for rolling mills.
