摘要

The fe3 + cations of the edges of a strip of hot rolled sheet and wound at the output of a strip mill, characterized in that it projects on the lateral parts of the coil, called sections, a vitrifiable powder, its contact with the coil of the steel at the output of the hot rolling, the sheet strip is cooled to a temperature lower than the temperature of the winding, the cooling of the strip ensuring the solidification of an enamel sealed at the surface of the slices of a coil and the air tightness of the space contained between the turns of the coil.
