Abstract
The cooling section of an annealing furnace is described as having the capabilities of maintaining, increasing, or decreasing the temperature of a strip of metal as it passes through the section. Moreover, special means are provided for forming around the cooling device, used in the cooling of the gas impinged against the traveling strip of metal, a cold sink which traps and prevents the backflow of cooled gas through the cooling device into the section, thereby eliminating the formation in the section of undesirable cold spots which adversely affect temperature uniformity in the section.
