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.

Abstract: The invention relates to a device and a method for cooling a roll. The roll concerned can be a roller in a roll stand or a measuring roll. The device comprises a cooling shell having a cross section in the shape of a section of a circular arc, for covering a surface region of the roll (200), wherein, in the region of an edge of the cooling shell, a bearing is formed with a pivot joint (120) with an axis of rotation running perpendicular to the circular arc-shaped cross-section, for pivoting the cooling shell about the axis of rotation. According to the invention, in order to ensure that the size of the cooling gap during the rolling operation or during the operation of a measuring roll is always autonomously optimally set, the bearing has a degree of freedom in radial direction r with respect to the circular arc-shaped cross-section of the cooling shell, such that the cooling shell is mounted in the bearing in such a way as to be freely movable in the radial direction.

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 method and a device for controlling a parameter, for example the profile or the flatness, of a rolled stock in strip form. A cooling jacket that can be brought up to the roll and is designed to be variable in its effective length b in the circumferential direction of the roll is used as a final controlling element.

Abstract: To increase the load-carrying capacity or rolling capacity of a roll assembly in a rolling mill, throttle elements are used, which shut off the lateral flow of the lubricating film in a partial region between the roll neck and the bearing surface of the roll neck bearing assembly, thereby bringing about an increase in pressure in the lubricating film. At least one throttle element is embodied as an annular segment, forming an angular shut-off region for the lubricant in the annular gap. The invention makes it possible for existing installations to be easily retrofitted, without the need for structural modifications. In the case of new installations, the same load-carrying capacity as before can be provided while the dimensions of the installation space are reduced. The load-carrying capacity of the bearing assembly can be flexibly adjusted based on the dimensions of the shut-off region for the flow of lubricant.
