Abstract
In a process in which strip metal is subjected to heating while suspended as a catenary in a heating zone, the strip is passed into the heating zone in a condition in which the lower surface is slightly elongated in relation to the upper surface. The differential elongation may be due to 'coil set' in the strip feed coil or may be applied by a roller leveller or equivalent mechanism during passage from a feed coil to the heating zone. The procedure is conveniently employed to control edge creep and improve flatness in stoving coated strip or in annealing operations.
