  • Publication number: 20190271066
    Abstract: A hot-dip-coated, non-skin-passed, cold-rolled metal strip is provided. The metal strip is obtained by passing the metal strip through a bath of molten metal, wiping the coated metal strip with nozzles that spray a gas on each side of the strip and making the strip pass through a confinement zone. The metal coating of the metal strip includes a waviness Wa0.8 of less than or equal to 0.70 ?m, 0.2 to 8% by weight of aluminum and magnesium in the following proportions: 0.1 to 8% by weight of magnesium for an aluminum content equal to or greater than 0.2% but less than 2% by weight or a content greater than 5% but less than or equal to 8% by weight of magnesium for an aluminum content equal to or greater than 2% but less than or equal to 8% by weight, and up to 0.3% by weight of additional elements, the balance being zinc and inevitable impurities. Metal parts are also provided.

  • Publication number: 20120052206
    Abstract: The subject of the invention is a process for manufacturing a metal strip having a metal coating for corrosion protection, comprising the steps consisting in: making the metal strip pass through a bath of molten metal; then wiping the coated metal strip by means of nozzles that spray a gas on each side of the strip, said gas having an oxidizing power lower than that of an atmosphere consisting of 4% oxygen by volume and 96% nitrogen by volume; and then making the strip pass through a confinement zone bounded: at the bottom, by the wiping line and the upper faces of the wiping nozzles, at the top, by the upper part of two confinement boxes placed on each side of the strip, just above the nozzles, and having a height of at least 10 cm in relation to the wiping line and on the sides, by the lateral parts of the confinement boxes, the atmosphere in the confinement zone having an oxidizing power lower than that of an atmosphere consisting of 4% oxygen by volume and 96% nitrogen by volume and higher than that
