Publication number: 20230279527Abstract: A method for producing steel strip, in particular hot strip in the form of coiled coils or in the form of folded individual sheets, in which a steel melt is first produced, this is then formed into a strand in a continuous casting system, the strand is then fed into a heating unit and the heated strand is then rolled into hot strip in a subsequent rolling mill. The casting of the strand, the passage through the heating unit, and the rolling take place in a continuous process. To be able to produce hot-rolled steel strips in the most energy-efficient way possible and to make these strips available for further processing into high-quality cold-rolled and, if necessary, coated strips, the invention provides that, first of all, a steel melt is produced.Type: ApplicationFiled: June 29, 2021Publication date: September 7, 2023Applicant: SMS GROUP GMBHInventors: Ingo SCHUSTER, Thomas HENKEL, Volker WIEGMANN, Markus REIFFERSCHEID, Hans FERKEL

Patent number: 8596335Abstract: A method for continuous casting from molten metal, where metal flows vertically downward from a mold and the metal strip is then guided vertically downward along a vertical strand guide, cooling as it moves. The strip is then deflected from the vertical direction to the horizontal direction. In the terminal area of the deflection of the strip into the horizontal direction or after the deflection into the horizontal direction, a mechanical deformation of the strip is carried out. The strip is cooled at a heat-transfer coefficient of 3,000 to 10,000 W/(m2 K) in a first section downstream of the mold and upstream of the mechanical deformation of the strip. In a second section, downstream of the cooling, the surface of the strip is heated to a temperature above Ac3 or Ar3 by heat equalization in the strip, after which the mechanical deformation is carried out in a third section.Type: GrantFiled: December 28, 2006Date of Patent: December 3, 2013Assignee: SMS Siemag AktiengesellschaftInventors: Uwe Plociennik, Jens Kempken, Peter Jonen, Ingo Schuster, Tilmann Böcher

Patent number: 8408035Abstract: The invention relates to a method and a system for the production of hot-rolled strip silicon-alloy steel for further processing into grain-oriented sheets, such as electrical sheets, wherein a cast product, in this case a thin slab, for example, with a maximum thickness of 120 mm, is subjected to thermal pretreatment and to a subsequent rolling process on a hot-rolling line to set a desired recrystallization state. The invention proposes an intake temperature (Tin) of the cast product (2) into the hot-rolling line (9a or 9b) of at least 1200° C., and preferably in excess of 1250° C., which should be controlled during pretreatment by adding at least one preheating stage (3) and one intensive heating stage (6) to ensure the final rolling temperature (TFR).Type: GrantFiled: June 22, 2007Date of Patent: April 2, 2013Assignee: SMS Siemag AGInventors: Ingo Schuster, Christoph Klein, Mario Sucker, Heribert Neifer

Publication number: 20120297849Abstract: The invention relates to a method for hot-rolling a slab (1), especially a steel slab, the slab (1) being subjected to at least two shaping steps at different temperatures in a hot-rolling mill (2), the slab (1) being cooled between two such shaping steps. In order to prevent ferrite from forming too soon during the hot-rolling, the slab (1) is cooled such that the lateral end sections (3, 4) of the slab (1) are cooled with a lower cooling efficiency than a center section (5) of the slab (1). The invention further relates to a hot-rolling mill (2) for hot-rolling a slab.Type: ApplicationFiled: December 6, 2010Publication date: November 29, 2012Applicant: SMS SIEMAG AKTIENGESELLSCHAFTInventors: Klaus Berchem, Ingo Schuster, Dirk Schmidt

Patent number: 7922840Abstract: A method for producing hot-rolled strip from austenitic stainless steels. In a first step, a cast product is subjected to a rolling operation in a rolling mill with a finishing train, and, in a second step, a heat treatment is carried out to prevent susceptibility to corrosion, especially intergranular corrosion due to chromium carbide precipitation. To establish the final rolling temperature (Twe), a run-in temperature (Tein) of the cast product into the finishing train of the rolling mill that is above 1,150° C., and preferably above 1,200° C., is established by a multistage heating process, especially a two-stage heating process, which comprises a preheating stage and an intensive heating stage, and the heat treatment is carried out by directly utilizing the rolling heat.Type: GrantFiled: May 15, 2009Date of Patent: April 12, 2011Assignee: SMS Siemag AktiengesellschaftInventors: Ingo Schuster, Manfred Albedyhl
