Abstract
An installation for the continuous coating of a strip, especially for the galvanizing of sheet steel. The object of the invention is to improve the quality of the coating and the uniformity of its crystallization, especially for thin sheets with low coating thicknesses. To achieve this result, the minimized flouring nozzle or nozzles are placed in an enclosure from which the strip leaves through a narrow slit and in which is provided means for maintaining a protective atmosphere inside this enclosure. Preferably, this enclosure is one with an enclosure surrounding the draining means, and means for recycling the protective atmosphere and for purifying it with respect to oxygen are provided.
