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: 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: 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 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.
