Patent number: 9364878Abstract: The invention relates to a method, a computer program and a rolling mill train for cold rolling a metal strip (200). In order to achieve a shortening of undesired off-gauge lengths, the method according to the invention provides that the head (210) of the metal strip (200) already undergoes a thickness reduction at the first active rolling stand (n) in the rolling mill train, and then is transported on to the next rolling stand, in order to undergo a further thickness reduction there. The method according to the invention also provides for further reducing the initial pass thickness at the n-th rolling stand in accordance with the tensile stress that has built up in the meantime between the n+1-th and the n-th rolling stand.Type: GrantFiled: June 6, 2012Date of Patent: June 14, 2016Assignee: SMS Group GmbHInventors: Andreas Ritter, Peter Sudau, Markus Koch

Patent number: 8544526Abstract: Energy is recovered from steel products produced in a steel mill where the products are transported into a storage area by first extracting heat from the steel products prior to or after transport into the storage area by heat exchangers for a predetermined period in which residual heat of the steel products is transferred by the heat exchangers into a heat-transfer medium to heat same. The heated transfer medium is then transferred via heat-transfer transport lines for power generation or for direct use of the process heat in other heat consumers. This transport of the heat-transfer medium from the heat exchangers to the power-generating plant in the heat-transfer transport lines is carried out only at pump feed pressure or using as a heat-transfer medium liquid mineral or synthetic thermal oil or a salt melt so as not to build up a steam pressure above 2 bar.Type: GrantFiled: March 2, 2010Date of Patent: October 1, 2013Assignee: SMS Siemag AGInventors: Peter Sudau, Juergen Seidel, Horst Gaertner, Axel Stavenow

Patent number: 8499821Abstract: A method for the detection and classification of surface defects on continuously cast products using topographical information about the appearance of continuously cast surface defects and/or flaws are determined with respect to their exact position, evaluated with respect to their location and dimensions, and eliminated in accordance with the evaluation prior to further machining of the product, or are prevented by optimizing the process. The defects and/or flaws on the slab surface of the continuously cast preliminary product are detected and are stored with respect to their exact position and a detection of defects and/or flaws on the finished product is carried out and stored with respect to their exact position, and in that the information from the preliminary product is then compared with the information from the surface inspection on the finished product.Type: GrantFiled: April 2, 2008Date of Patent: August 6, 2013Assignee: SMS Siemag AGInventors: Dieter Rosenthal, Stephan Schulze, Ingo Schuster, Peter Sudau, Rainer Fackert, Andreas Weinert, Wilfried Schumacher

Publication number: 20120118526Abstract: In hot strip plants, after casting, the residual heat of a partial quantity of the slabs has hitherto been used such that the slabs either are directly rolled or are placed warm or hot in the furnace. The remaining slabs normally cool after casting in a hall through which flows air and are stacked before their further transport. The same applies to the residual heat present in the coils after winding, which often cool in the coil-storage area in air. The cooling energy of the continuous-casting plant likewise escapes unused into the surroundings.Type: ApplicationFiled: March 2, 2010Publication date: May 17, 2012Inventors: Peter Sudau, Juergen Seidel, Horst Gaertner, Axel Stavenow
