Abstract
Treatment process limiting the overoxidation of the sides of a coiled, hot-rolled sheet strip delivered from a strip mill, characterized in that a vitrifiable powder is sprayed onto the lateral portions of the coil, called edges, fusing at the time of its contact with the steel coil delivered from hot-rolling, the sheet strip undergoing cooling at a temperature below the coiling temperature, the cooling of the strip ensuring the solidification of an impervious enamel on the surface of the coil edges and air-tightness of the space contained between the turns of the coil.
