  • Patent number: 11905572
    Abstract: A furnace for the heat treatment of a metal product includes constitutive elements, each having a thermal inertia property determined from physical parameters. The constitutive elements include walls delimiting at least partially the furnace, a heating unit for heating the metal product, and a rapid heating element for heating the metal product. The furnace also includes a control circuit for controlling the heating unit and/or the rapid heating element, based on one or more thermal inertia properties of one or more constitutive elements of the furnace, and at least based on a ground of a constitutive element of said furnace.

  • Patent number: 11898971
    Abstract: A method and a device for determining the material properties of a polycrystalline, in particular metallic, product during production or quality control of the polycrystalline, in particular metallic, product by means of X-ray diffraction using at least one X-ray source and at least one X-ray detector. In this case, an X-ray generated by the X-ray source is directed onto a surface of the polycrystalline product and the resulting diffraction image of the X-ray is recorded by the X-ray detector. After exiting the X-ray source, the X-ray is passed through an X-ray mirror, wherein the X-ray is both monochromatized and focused, by the X-ray mirror, in the direction of the polycrystalline product and/or the X-ray detector, and then reaches a surface of the metallic product.

  • Publication number: 20230023783
    Abstract: A radiant element for heating an oven is disclosed. The radiant element comprises a first end; a second free end; a radiant structure between said first end and second end; a conduit for an energy feed inside said radiant structure; a first attachment leg for mechanically coupling the radiant structure to a support, a first coupling means comprising a first portion arranged to be stationary with respect to said support, and a second portion stationary relative to said first leg, the first portion and the second portion being mechanically coupled via a first interface so as to allow a relative displacement between the first portion and second portion.

  • Publication number: 20220260482
    Abstract: A device for the contactless determination of at least one property of a metal product during the metallurgical production of the metal product comprises a housing and at least one measuring device comprising a transmitting unit and a receiving unit. An electromagnetic field is generated by the transmitting unit and directed onto the metal product, thereby inducing a physical interaction in the material of the metal product, and a remaining and/or resulting part of this physical interaction is subsequently received by the receiving unit. At least one component of the measuring device comprising the transmitting unit and/or the receiving unit can be moved relative to the housing or the metal product moving therein, in order to thereby set or selectively change a predetermined distance to the metal product for the transmitting unit and/or the receiving unit.

  • Patent number: 11230749
    Abstract: A method for operating an annealing furnace to anneal a metal strip provides that, initially, at least one target material property (MPTarget) is specified for a point or a section of the metal strip after passing through the annealing furnace. In addition, information (E) on the metal strip is provided before or in the annealing furnace. A calculation of a target temperature distribution (TTarget) and/or a target speed (VTarget) of the metal strip in the annealing furnace is then carried out with the assistance of a computer-aided model as a function of the target material properties and the specified information. The target temperature distribution and/or target speed calculated in this manner is/are subsequently set in the annealing furnace in order to transfer the material property of the metal strip behind the annealing furnace to the desired target material property MPTarget.
