| Number | Title | Issue Date |
| 7110840 | Master control system for a rolling mill A master control system for a rolling mill, especially a mill train, having at least one rolling stand driven by means of a drive system, and the master control system having an automation device for the open-loop and/or closed-loop control of the rolling stand. The... | 09/19/2006 |
| 7093342 | Hot rolling thin strip Thin steel strip is passed through a pinch roll stand comprising pinch rolls to a rolling mill comprising a pair of work rolls and upper and lower backing rolls. Strip passes through the bite between the work rolls and strip squeezing forces are applied between the ... | 08/22/2006 |
| 6993947 | Device and method for calibrating a multiple-roller flattener A metal measurement plate (5), having a size suitable for being placed between the set of upper rolls and the set of lower rolls of the leveler, has positioning means (60, 61, 62) for positioning it with respect to the rolls in the leveling direction, ... | 02/07/2006 |
| 6966207 | Shape detecting apparatus A shape detecting apparatus for controlling the tension of a rolled plate, is composed of a pair of fixing members, a supporting frame and a plurality of shape detecting units. The shape detecting units are fixed detachably in a close proximity of the supporting fra... | 11/22/2005 |
| 6769279 | Multiroll precision leveler with automatic shape control An automatically controlled multi-roll precision leveler for flattening a strip of material, such as a metal strip. A metal strip product may be fed into the leveler, typically from a coil. The leveler uses multiple work rolls to flatten the strip as it passes throu... | 08/03/2004 |
| 5778717 | Process and device for rolling bands with uneven thickness and/or length distribution over their width The present invention relates to a process and to a device for the rolling of bands (B) with uneven thickness and/or length distribution over their width by using at least one control roller (5, 9, 21, 27, 41, 43) located on the inlet and/or outlet side o... | 07/14/1998 |
| 5680784 | Method of controlling form of strip in rolling mill A method of controlling a form of a strip in a rolling mill. A plurality of paired data of manipulation amounts of form control actuators, and amounts of variations in the form of the strip corresponding to the manipulation amounts are prepared, as protot... | 10/28/1997 |
| 5172579 | Steering control apparatus for rolled plates A steering control apparatus for a rolled plate (1) rolled by a rolling mill (2), and which has a means (15) for obtaining by means of fuzzy inference a leveling amount of its polarity (15A) of the rolling mill for the snaking control of the rolled plate,... | 12/22/1992 |
| 4981028 | Method for cold-rolling sheets and strips In a method for cold-rolling sheets and strips, measured values which characterize the surface evenness, especially the tensile stress distribution, are formed on the delivery side of a rolling mill and, in dependence thereon, adjusting members of the rol... | 01/01/1991 |
| 4674309 | Apparatus for correcting the thickness profile of a strip to be rolled in a multiple stand hot strip mill train A method and apparatus for a very exact correction of the thickness profile of strip rolled in a multi-stand hot strip mill. A measuring device determines the distribution of tensions in the cross-section of the strip (19). The measuring values are proces... | 06/23/1987 |
| 4656854 | Rolling mill eccentricity compensation using measurement of sheet tension A method of eliminating thickness changes in material exiting a stand or stands of a rolling mill, the changes being caused by the eccentricity of one or more rolls of the mill. The method includes the steps of engaging the material with a device that mea... | 04/14/1987 |
| 4587819 | Method and circuit for flatness control in rolling mills A method for controlling flatness in cold-rolling mills having a roll stand with at least six rolls including intermediate and working rolls capable of being deflected, includes measuring tensile stress distribution over the width of a strip to be rolled ... | 05/13/1986 |
| 4289005 | Process and device for controlling the flatness of a cold-rolled metal sheet A process for controlling the flatness of a metal sheet subjected to a cold-rolling operation by the measurement of the tensions in different regions of the width of the sheet. There are at least three regions. The process comprises calculating the sum of... | 09/15/1981 |
| 4269051 | Rolling mills and operation thereof To operate a rolling mill to roll metal strip with a satisfactory degree of flatness, signals from tension detecting means located downstream of the mill rolls are used continuously to determine the best symmetrical parabola which fits the shape of the st... | 05/26/1981 |
| 4261190 | Flatness control in hot strip mill The flatness of metal strip being rolled in a hot strip mill is improved by applying higher than normal interstand tensions with maximum permissible tensions being based upon preestablished maximum allowable width reductions due to interstand tensions. Th... | 04/14/1981 |
| 4199967 | Method of controlling a shape of a rolled sheet The forward slip and the backward slip at a first stand are dependant upon a draft, the back tension, the front tension, and the shape of a sheet in a tandem type rolling mill. It is difficult to control the shape solely by detecting the tension distribut... | 04/29/1980 |
