Abstract
A process and an installation for the continuous application of an oxidizable coating to a strip. The object of the invention is to provide an improvement in the recycle ratios and a savings of inert replenishing gas in an installation, in the enclosure which protects the draining means for controlling the coating, is recycled. To achieve this result, provision is made for the continuous purification of this gas by bringing it into contact with a reductive substance. If protective enclosure also contains the minimized flouring nozzles, zinc vapor can be introduced into the gas. This zinc vapor reacts with the oxygen and produces the nuclei by condensation.
