Patent number: 11313023Abstract: Equipment for manufacturing a metal strip coated by a process that includes vacuum-depositing a layer of an oxidizable metal or an oxidizable metal alloy on a metal strip precoated with zinc or with a zinc alloy, then coiling the coated metal strip, then oxidizing a surface of the metal strip coated with the oxidizable metal or oxidizable metal alloy and treating the oxidized wound coil with a static diffusion treatment to obtain a strip having a coating that includes, in an upper portion, a layer of an alloy formed by diffusion of the oxidizable metal or the oxidizable metal alloy in all or part of the zinc or zinc alloy layer. The equipment includes a device for galvanizing the metal strip, a vacuum deposition coating device, and a static heat treatment device operating in a controlled atmosphere.Type: GrantFiled: August 8, 2018Date of Patent: April 26, 2022Assignee: ArcelorMittalInventors: Luc Vanhee, Maxime Monnoyer, Bruno Schmitz, Benoit Deweer, Eric Silberberg

Patent number: 10752982Abstract: An installation for hot dip coating a metal strip is provided. The installation includes a device for moving the metal strip along a path, a pot for containing a melt bath and a wiping system including at least two nozzles placed on either side of the path downstream the pot. The wiping system has a box with a lower confinement part confining an atmosphere around the metal strip upstream of said nozzles and an upper confinement part confining the atmosphere around the metal strip downstream of the nozzles, first moving means for vertically moving the lower confinement part with respect to the pot and second moving means for vertically moving the upper confinement part with respect to both the pot and the lower confinement part. The nozzles are vertically movable relative to the pot.Type: GrantFiled: June 10, 2014Date of Patent: August 25, 2020Assignee: ARCELORMITTALInventors: Peter Schwander, Axel Wendt, Andreas Steffen, Hubert St Raymond, Maxime Monnoyer, Julien Benoit, Jean Michel Mataigne, Paul Durighello

Patent number: 10711339Abstract: A method deposits a metal alloy coating on a substrate using a vacuum deposition facility. The facility is equipped with a vapour generator/mixer comprising a vacuum chamber enclosure provided with an inlet and an outlet for the substrate. The enclosure includes a vapour deposition head and an ejector is provided to create a jet of metal alloy vapour of sonic velocity towards the surface of the substrate and perpendicular thereto. The ejector is in sealed communication with a separate mixer device, which is itself connected upstream to at least two crucibles respectively, these containing different metals in liquid form, each crucible being connected to the mixer by its own pipe. The method uses a series of partitions to create alternating layers of metal vapours. The metal vapours enter the mixer inlet of the mixer at a velocity from 5 to 50 m/s to provide better homogeneity.Type: GrantFiled: November 21, 2018Date of Patent: July 14, 2020Assignee: Arcelormittal FranceInventors: Eric Silberberg, Luc VanHee, Bruno Schmitz, Maxime Monnoyer

Patent number: 10612144Abstract: The present invention provides a metal sheet including a steel substrate coated on at least one face with a coating including from 0.1 to 20% by weight of magnesium, optionally from 0.1 to 20% by weight of aluminum, the balance being zinc, potential impurities linked to the method and optionally one or more additional elements selected from among Si, Sb, Pb, Ti, Ca, Mn, Sn, La, Ce, Cr, Ni, Zr and Bi, the content by weight of each additional element being less than 0.3%. The coating itself is covered by a layer, based on zinc hydroxychloride, having a chlorine coating weight of at least 1 mg/m2. The layer does not include hydrozincite or mixed hydroxycarbonates of zinc and aluminum or water-soluble compounds of sodium or potassium. The present invention also provides a method to obtain the metal sheet.Type: GrantFiled: July 4, 2014Date of Patent: April 7, 2020Assignee: ArcelorMittalInventors: Daniel Chaleix, Christian Allely, Maxime Monnoyer, Pascale Feltin
