A linear bearing plate, or liner, for use within a rolling mill stand including lubrication ports in fluid communication with a lubrication source. Lubrication ports provide areas of active lubrication which are surrounded by areas of passive lubrication so as to provide adequate lubrication during a rolling campaign. Lubricant port discharge can be metered by nozzles or controlled by altering the geometry of the lubricant-carrying conduits defined on a surface of the plate.
F16C 32/06 - Bearings not otherwise provided for with moving member supported by a fluid cushion formed, at least to a large extent, otherwise than by movement of the shaft, e.g. hydrostatic air-cushion bearings
An oil film bearing for supporting a roll neck in a rolling mill, suitable in particular for transmitting high bearing forces when the bearing partners are slightly and slowly moved with respect to each other, has a bearing surface into which are incorporated rods made of a friction- reducing material (e.g., low friction compounds), which extend in a substantially perpendicular direction to the bearing surface. The rods are deformed during heat processing to define a bearing surface. The bearing partner, such as a roll sleeve, rests on the free face of the deformed rods.
A lubrication delivery system for a rolling facility having a plurality of roll stands. A centralized lubrication source is arranged to supply lubrication to a plurality of liners within the roll stands during a rolling campaign. The lubrication source can supply one or more lubricants via controlled conduits in fluid communication with the liners. Liners are provided with a plurality of conduits for directing pressurized lubricant from the centralized lubricant source so as to minimize lubricant loss. A plurality of different lubricants may be provided at a centralized source with a controller or other device directing a flow of pressurized lubricant to the plurality of roll stands during the campaign.
A system and method of use within a rolling facility comprising a plurality of mill stand assemblies with each assembly further comprising components including liners, chock sets, and rolls. An RFID system utilizes RFID tags on each of the plurality of components in order to track and/or monitor characteristics of either the entire mill stand assembly or individual components thereof. An RFID tag reader may be incorporated within a mill stand or may include portable devices. In one embodiment, RFID tag interrogation occurs both at the mill stand and at a remote site at which bearing assembly occurs. A unique combination of mill stand components can be assembled, identified and monitoring during successive rolling campaigns allowing the mill operator to make adjustments toward improving the quality of rolled product.
A linear bearing assembly including a linear bearing plate (50), a base plate (52) to support the linear bearing plate within a machine, a sealing structure (54) to seal a volume (53) defined between the linear bearing plate (50) and the base plate (52), and a fluid (56) adapted to be injected into the volume via at least one injection port. The fluid (56) is injected at a sufficient pressure so as to alter an orientation of the linear bearing plate (50) or the base plate (52) toward an initial geometric orientation.
A linear bearing plate, or liner, for use within a rolling mill stand, said liner including lubrication ports in fluid communication with a lubrication source. A centralized lubrication source can provide a predetermined lubrication to a plurality of mill stands in response to a signal, such as from a rolling facility operator. Lubrication ports provide areas of active lubrication which are surrounded by areas of passive lubrication so as to provide adequate lubrication during a rolling campaign.
