Patent number: 11529670Abstract: A method for cutting a cast strand or intermediate strip using shears. In order to facilitate improved rolling of the section having significantly reduced thickness, the method according has the following steps: a) bringing part of the completely solidified cast strand or intermediate strip in the conveying direction (F) of the cast strand or intermediate strip in front of the shears; b) placing a first blade of the shears onto the one surface of the cast strand or intermediate strip and placing a second blade of the shears onto the other surface of the cast strand or intermediate strip and performing a cut by carrying out a relative movement of the two blades, wherein at least one of the blades is in a pushed-forward position; c) upset forging or upset forging with stamping a wedge-shaped contour on the end of the cast strand.Type: GrantFiled: September 24, 2018Date of Patent: December 20, 2022Assignee: SMS group GmbHInventors: Luc Neumann, Michael Pander, Björn Kintscher, Bernhard Ehls

Patent number: 10010915Abstract: A method for producing a metal strip (1) by casting and rolling, wherein first a slab (3) is cast in a caster (2) by dispensing metal from a mold (4), wherein the slab (3) is deflected from the vertical direction to the horizontal direction in the region of a strand guide (5), wherein the slab (3) is then tempered in a furnace (6), wherein the slab (3) is rolled in a rolling train (7) after the furnace (6) and wherein the slab (3) is processed either in discontinuous batch operation or in continuous or semi-continuous operation in dependence on a specified manner of operation. According to the invention, in order to create optimal process conditions for all desired operating modes, the slab (3) to be rolled or the metal strip (1) being rolled is subjected to heating in the region of the rolling train (7) at least between two roll stands (8, 9, 10, 11, 12, 13, 14) by means of an inductor (15).Type: GrantFiled: March 10, 2014Date of Patent: July 3, 2018Assignee: SMS Group GmbHInventors: Christoph Klein, Christian Bilgen, Christian Klinkenberg, Michael Pander, Luc Neumann, Dieter Rosenthal, Cosimo Andreas Cecere

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: 20130098736Abstract: A transport device for slabs, which device is arranged between at least two casting machines and at least one rolling mill. The transport device has at least two linear and stationary conveyor sections on which a slab can be conveyed in a conveying direction. The transport device further has at least two linear conveyor sections which are arranged to be pivotable in order to convey a slab at an angle to the conveying direction. In order to improve guidance of the slabs and provide a flexible transport of the slabs from the casting machines to the rolling mill, the at least two linear, pivotable conveyor sections are arranged to be pivotable independently of one another.Type: ApplicationFiled: December 14, 2010Publication date: April 25, 2013Applicant: SMS SIEMAG AKTIENGESELLSCHAFTInventors: Luc Neumann, Kilian Kaupper, Christian Bilgen, Alexander Meyer, Tilmann Bocher, Marcel Gathmann

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

Publication number: 20120043049Abstract: The invention relates to a process for the continuous casting of a slab (1), in particular of steel, wherein the cast slab (1) is conveyed through a furnace (2) and the slab (1) is subjected to a descaling operation. To increase the quality of the slab by reducing scale, the invention provides for the slab surface to undergo reduction in at least one section (3) of the furnace (2) as a result of an atmosphere consisting of an inert gas and hydrogen (H2) or of pure hydrogen being maintained in said section (3) of the furnace (2). The invention further relates to an apparatus for the continuous casting of a slab.Type: ApplicationFiled: April 19, 2010Publication date: February 23, 2012Applicant: SMS SIEMAG AKTIENGESELLSCHAFTInventors: Christian Klinkenberg, Christian Bilgen, Tilmann Böcher, Luc Neumann
