Abstract

The drying procedure, in which a coated steel strip (1) is passed vertically through a drying oven (3) with hot air injected at the top and bottom to prevent vapours condensing on the relatively cool walls of the oven, includes the formation of a dynamic brake by injecting hot air (13a, 13b) between the top and bottom of the oven at a distance between its outlet and inlet and creating a pressure above atmospheric inside the oven to limit the entry of parasite cold air by a stack effect. The injected air is drawn out of the oven at one or more points (4), with the dynamic brake created below and close to one of the points, and the air drawn from the oven is recycled.
