Abstract
The invention relates to a method of protecting devices designed for the galvanization of metal products, in particular for the galvanization of continuous drive cylinders used when galvanizing sheet on a single surface. A surface layer of the cylinders is coated with one or more oxide, one or more silicate, one or more zirconate, one or more mixed inorganic compound. Examples of the oxides include Mg, Ca, etc. Examples of the silicates include Al etc. Examples of the zirconates include Mg etc. Examples of the mixed inorganic compounds include serpentines, amphiboles, silicon carbide. The oxides are applied directly to the cylinder surface to be formed "in situ", for example, by heating in air to approximately 1000.degree. C.
