Abstract

Device for controls rolled stock cross-section in rolling strip or sheet between two work rolls by local thermal effect in the region of the rolls. Heating elements are provided before the work rolls over the strip width or on a work roll distributed over its length. The elements may be controlled dependent upon the longitudinal tensile stress or the thickness variation over the stock width. The device gives rapid variation in gap geometry over restricted zones without unreliability of e.g. spray control.
