| 7251978 | Roll stand for producing plane roll strips having a desired strip profile superelevation The aim of the invention is to improve known roll stands (10) which are characterized by working rolls (1,2) of various diameters, in such a way that a strip is obtained which is largely free of tensions and undulations, has a desired strip profile sup... | 08/07/2007 |
| 4881392 | Hot leveller automation system This invention relates to a method of, and apparatus for, controlling a levelling machine for metal plates and, more particularly, to control flatness in a plate mill hot leveller.... | 11/21/1989 |
| 4676085 | Rolling mill for controlling the contour of a workpiece A back up roll assembly for supporting an intermediate roll and an upper work roll consists of a plurality of rotatable rollers spaced apart on a common shaft by fixed saddles and in engagement with the intermediate roll. The number of saddles exceeds one... | 06/30/1987 |
| 4656855 | Crown control method for a multi-roll rolling mill A method is set forth for use in crown control in a multi-roll rolling mill, the method including the steps of: setting in advance a shape of a thermal crown of a work roll corresponding to various rolling conditions and a changing gradient of a mechanica... | 04/14/1987 |
| 4577480 | Method and apparatus for controlling rolling correction in rolling mill In a rolling mill of the type in which horizontal pushing forces are exerted to a work roll exerted with a rolling force so as to bend the work roll, thereby controlling the flatness of a strip being rolled, a method and apparatus for controlling rolling ... | 03/25/1986 |
| 4481799 | Arrangement for regulating a rolling mill for metal rolling An arrangement for regulating a rolling mill for metal rolling, the work rolls of which are supported by guided roll shells of a lower controlled deflection roll and an upper controlled deflection roll, the roll shells being supported by means of hydrosta... | 11/13/1984 |
| 4458515 | Method and apparatus for variably controlling transverse rigidity of rolling machine In a sheet rolling mill having work rolls and backup rolls, rolling of flat sheets is facilitated by controlling constant the transverse rigidity or deflection in the direction of width of rolls. The rolling force is detected, and based on the rolling for... | 07/10/1984 |
| 4222255 | Rolling device having at least one controlled deflection roll A rolling device or mill having a controlled deflection roll possessing a fixed support and a radially movable roll shell rotatable about the fixed support. Between the roll shell and the material to be rolled there is located an intermediate roll having ... | 09/16/1980 |
| 4131004 | Rolling mill gauge and flatness calibration system A frame carrying one or more transducers is inserted between the work rolls of a mill stand with the transducers positioned parallel to the roll axis. The outputs of the transducers are connected to a display device which when load is applied to the rolls... | 12/26/1978 |
