Publication number: 20230256489Abstract: A roll stand of a rolling mill is supplied with a metal strip by an upstream supply device at an in-feed speed (v), with said metal strip being rolled in the roll stand. A measuring device between the supply device and the roll stand detects a respective thickness value (d) of the metal strip for consecutive sections of the metal strip and supplies said value to a control device of the rolling mill. The control device determines final thickness deviations based on the preliminary thickness deviations. The control device determines a respective control value (A2, A3) for the roll stand and/or the supply device for the sections of the metal strip based on the final thickness deviation of the respective section of the metal strip and the final thickness deviations of multiple preceding and/or subsequent sections of the metal strip.Type: ApplicationFiled: May 26, 2021Publication date: August 17, 2023Inventors: Matthias DRESSLER, Daniel KOTZIAN, Martin SCHÖNHERR, Srdan SEKULIC

Patent number: 11364526Abstract: A metal strip is rolled in a roll stand and a control device for the roll stand determines, by means of a working cycle, a number of manipulated variables for flatness actuators of the roll stand and actuates them accordingly. The control device implements an optimizer, which provisionally sets the current correction values, and determines a totality of flatness values. Then, the optimizer minimizes the relationship by varying the current correction variables. When determining the current correction variables (s), the optimizer considers linear ancillary conditions, based at least in part on a vector having the ancillary conditions upheld by the current correction values and a vector having the ancillary conditions upheld by the difference of the current correction values relative to the correction values of the preceding working cycle. The control device determines the manipulated variables for the flatness actuators in consideration of the determined current correction variables.Type: GrantFiled: June 12, 2018Date of Patent: June 21, 2022Assignee: Primetals Technologies Germany GmbHInventors: Matthias Dressler, Andreas Maierhofer, Andreas Müller, Alexander Thekale, Slobodan Veljovic

Publication number: 20220097112Abstract: A metal strip is fed to a rolling stand by a feeding device and removed by a removing device. A control device cyclically determines, based on final thickness deviations of portions of the metal strip from a setpoint thickness of the metal strip on the exit side, setpoint values and outputs the determined setpoint values to final control elements. The final control elements include the feeding device, an adjusting device for the rolling gap of the rolling stand, a drive for driving rolls of the rolling stand, and/or the removing device. For the feeding device, the drive, and the removing device, the setpoint value is a setpoint speed or torque. For the adjusting device, the setpoint value is a setpoint rolling-gap value. The control device determines a setpoint value based on a number of final thickness deviations allowing for the inverse frequency response of the respective final control element.Type: ApplicationFiled: September 27, 2021Publication date: March 31, 2022Applicant: Primetals Technologies Germany GmbHInventors: Matthias Dressler, Daniel Kotzian

Patent number: 10854360Abstract: A power resistor comprises a tubular housing composed of metal and a resistor element received therein, wherein the housing has four side walls that extend along a longitudinal axis of the housing between two ends and define a rectangular cross-section. The housing comprises four edges of the four side walls at at least one of the two ends. Two of the four side walls have a respective incision at their edges for introducing a fastening element and the two other side walls have a respective clearance in alignment with the oppositely disposed incision to facilitate a placement of a tool at a fastening element introduced into the respective incision.Type: GrantFiled: June 15, 2018Date of Patent: December 1, 2020Assignee: VISHAY ELECTRONIC GMBHInventors: Matthias Dressler, Bertram Schott
