Patent number: 11898971Abstract: 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.Type: GrantFiled: June 24, 2020Date of Patent: February 13, 2024Assignees: SMS group GmbH, IMS Messsysteme GmbHInventors: Christian Klinkenberg, Ulrich Sommers, Helmut Klein, Alexandre Lhoest, Olivier Pensis, Horst Krauthäuser

Patent number: 8572826Abstract: A method and a device for improving the outer surface quality by an in-line outer surface treatment of slabs, which are produced in a continuous process from strand casting to hot rolling, with a heating furnace arranged between a CSP-casting machine and a hot rolling train. A defined surface of the slab with a layer thickness per slab side of up to 4 mm is oxidized in a targeted manner by an oxidation device. An oxidation treatment of the slab surface is combined with the following processing in-line method steps: prior to the oxidation treatment the outer surface of the slab is freed of naturally occurring scale by a scale washer, after the oxidation treatment a created oxidation layer as well as the newly formed scale is cooled, mechanically broken up in a roll pair and removed from the surface of the slab by a scale washer.Type: GrantFiled: January 10, 2011Date of Patent: November 5, 2013Assignee: SMS Siemag AktiengesellschaftInventors: Christian Bilgen, Tilmann Böcher, Luc Neumann, Marcel Gathmann, Christian Klinkenberg

Publication number: 20130014362Abstract: The aim of the invention is to improve the surface quality of slabs (5) having a thickness of up to 400 mm, that are produced in a continuous process from continuous casting to hot-rolling, for example according to the CSP method, by means of an in-line surface treatment. To this end, a defined surface layer of the slab (5) with a layer thickness per slab side of up to 4 mm is oxidised in a targeted manner by an oxidising flame or an oxidising gas mixture applied to the upper and lower sides of the slab (5) by means of an oxidation device containing nozzles or a similar device, said layer being removed later on during the process. The oxidation product on the slab surface can be solid or liquid.Type: ApplicationFiled: January 10, 2011Publication date: January 17, 2013Applicant: SMS SIEMAG AKTIENGESELLSCHAFTInventors: Christian Bilgen, Tilmann Böcher, Luc Neumann, Marcel Gathmann, Christian Klinkenberg
