Abstract: A cooling group for a laminar cooling device, including at least one cooling unit arranged above and below a strip to be cooled in order to supply the strip with a cooling liquid, including a central inlet via which cooling liquid is supplied, a distributing tube supplied with cooling liquid by the central inlet, and a number of supplying units supplied with cooling liquid from the distributing tube. Each supplying unit has a number of cooling nozzles via which cooling liquid is discharged onto the strip. In order to minimize the influence of the number of supplying units which are switched on or switched off, and thus have as little expenditure as possible, a volumetric flow rate regulating valve is arranged in or in front of the central inlet. The regulating valve is used to conduct a defined volume of cooling liquid through the central inlet per unit of time.

Abstract: A seal (100) for sealing a lubricant space prevents lubricant (320) escaping. A rolling stand has a seal of this kind. The seal (100) is made at least partially from elastic material. To enable a pressing force FR, with which the bottom face (112) of the seal is pressed against an opposite contact surface (218), for example of a roll journal (212), to be variably set, the seal (100) has at least two cavities, which are separated from each other in the circumferential direction and which are open towards the lubricant space of the bearing.

Abstract: A roll stand for the rolling of rolling stock, especially metal products. The roll stand includes at least two chocks for mounting at least one roll, the roll being rotatably mounted in the chocks by its two cylindrical roll necks. A cylindrical neck bushing is arranged on the roll neck with radial play. A rotationally fixed annual axial bearing is axially offset from the neck bushing. The bearing arrangement for the roll necks in the chocks is formed as a plain bearing, preferably a hydrodynamic oil film bearing. When subjected to a load in a rolling process, the neck bushing moves and deforms not only in the radial direction, but also in the axial direction.

Abstract: A method for operating a rolling technology or metallurgical system is disclosed. The rolling technology or metallurgical system comprises a device in which a rotating component is mounted with at least one sliding bearing. The sliding bearing is supplied with a lubricant. In order to enable improved operation of said bearings, in particular in rolling mills, a water-based, single-phase fluid to which at least one viscosity-increasing additive is added is used as the lubricant for the bearing.

Abstract: The invention relates to a strip deflector for deflecting a rolling medium from the surface of a metal strip. The invention further relates to a roll assembly, comprising a roll, adjacent to which the strip deflector is placed at a distance, and comprising the strip deflector according to the invention. The strip deflector consists substantially of a main body, in which a compressed-air chamber and a nozzle (116) connected to the compressed-air chamber in a flow-conducting manner are formed. The nozzle (116) comprises a first nozzle channel segment (116-I) connected to the compressed-air chamber (114) and a second nozzle channel segment (116-II) connected downstream. According to the invention, in order to improve the sealing action of the strip deflector with respect to the roll in a roll stand, the side wall (116-I-2) facing away from the tip (112) of the main body (110) is bent away from the tip (112) of the strip deflector, a second separation edge (119) thus being formed at the end of the second nozzle channel segment (116-II).

Abstract: An oil film bearing includes a journal bush and accommodates a conical roll journal of a backup roll in a rolling mill stand. In order to form a sufficiently large lubricant film gap between the inner side of the journal bush and the outer surface of the roll journal during rolling operation when passing through the angular range with maximum pressure load, and at the same time to prevent the axial forces acting on a fastening ring holding the journal bush on the roll journal in the axial direction from becoming too great, the journal bush to be designed in accordance with the following formula: 0.35

Abstract: A device for measuring a wear condition on the plain bearing surface of a sensor plate comprises a measuring apparatus, which has wear sensors of a sensor plate integrated into the plain bearing surface. To capture the material removal at the plain bearing surface due to wear an evaluation apparatus is in signal connection with the wear sensors. The evaluation apparatus is designed, with respect to programming, in such a way that a change, in particular an increase, in the ohmic resistance value of the electrical conductor of a certain wear sensor can be captured in dependence on its own material removal, in order to thereby ensure that the amount of the material removal at the plain bearing surface and/or the remaining thickness of the plain bearing surface at the location of said certain wear sensor can be inferred from the detected change in the resistance value.

CPC classification number: B21B31/074
Abstract: A volume flow regulating valve for controlling the volume flow of a fluid medium in two outflow ducts. The volume flow regulating valve is composed of a cylinder with a dual piston mounted axially displaceably in the cylinder, with a central pressure chamber being formed in the region of the barbell-shaped central piece of the dual piston. Aside from an inlet for the fluid medium, it is also the case that the two outlet ducts are provided at the central pressure chamber. The outlet ducts are arranged on the cylinder with such an axial spacing that—when the dual piston is situated in a central position in relation to the two outlet ducts—the first outlet duct—preferably partially covered by the first piston—and the second outlet duct—preferably partially covered by the second piston—each open up an equal opening cross-sectional area.

Abstract: A roll arrangement for rolling rolling material in a rolling system. The roll arrangement includes a roll that is rotatably mounted by its roll journal in a bearing bush of a chock. A ring gap for receiving a lubricant is formed between the bearing bush and the roll journal. The ring gap is sealed both on the ball side of the chock and on the side of the chock away from the balls, using sealing rings. In order to increase the load capacity or the rolling force of a roll arrangement while maintaining or reducing the construction size thereof and without the roll arrangement overheating, discharge channels are provided in a through-flow angular range of the bearing bush for discharging the lubricant out of the ring gap into an oil-receiving chamber.
