The present invention relates to a rolling facility and a rolling method. According to the present invention, the rolling facility comprises: a roughing mill having a roughing mill roll for pressing a material to be transferred; a finishing mill having a finishing mill roll, which is provided on a material transfer path, and pressing the material having passed through the roughing mill; a wiper device provided at a feed-in side of the finishing mill roll, polishing the surface of the finishing mill roll, and supplying cooling fluid to the material; and a cooling device provided on the material transfer path and cooling the material having passed through the finishing mill, wherein the wiper device can include a plurality of cooling header units for supplying the cooling fluid to the material at different positions.

Disclosed is a novel split header for use in a rolling mill. The split header has a mounting block and a quick-change header cartridge, wherein the mounting block is coupled to the quick-change header via a quick-disconnect feature, the quick-disconnect feature configured to enable uncoupling (in a toolless manner) of the quick-change header from the mounting block. Additionally, the quick-change header cartridge may be replaced by a dummy header cartridge that diverts water when stand is dummied, and a split base and header cartridge design. Further, the mounting block may have one or more sensors and the quick-change header may have an RFID tag, where the sensors and the RFID tag may communicate with a central computer.

A device and a method for applying a liquid medium to a roll, and/or to a rolled material, a slab or a roughed strip and/or for removing the liquid medium, wherein the device has at least one spray nozzle, at least one row of spray nozzles or at least one cooling bar for spraying on the medium and at least one plate element, which is designed for collecting the medium. The roll is designed for rolling rolled material, wherein the rolled material, the slab or the roughed strip is conveyed in a conveying direction. In order to allow an improved cooling effect of a roll to be cooled or an improved removal of descaling water, the plate element has on one of its surfaces at least one directing element, which is designed for diverting medium into a transverse direction, which lies horizontally and transversely in relation to the conveying direction.

A stripping device (7) for a roll stand (1) includes a stripper carrier (15) and a stripper (17) arranged on the stripper carrier (15). The stripper (17) has a main body (19) produced from a fiber-plastic composite. The main body has a main body bottom side (23), which contacts the stripper carrier (15). A felt layer (21) is arranged on a main body top side (25) of the main body (19) which is opposite the main body bottom side (23).

Disclosed is a spray ramp intended to lubricate and/or cool a laminated strip and/or pressure cylinders of a mill, including: a tubular shaft of which the hollow interior volume forms a fluid admission chamber; a chassis rigidly connected to the external wall of the shaft, extending along the tubular shaft; a plurality of nozzles distributed over the length of the chassis and supported by the chassis, arranged such that the jets form a fluid curtain; and a pipe system, inside the chassis, ensuring the supply of the nozzles from the through-bores provided in the tubular wall of the hollow shaft. The pipe system includes at least one pressure levelling chamber extending over the whole active length of the chassis and through which all the fluid supplying the plurality of nozzles passes.

A rolling mill, in particular a cold rolling mill, including: rolls or even sets of rollers comprising at least one pair of work rolls capable of defining a roll gap of a strip to be rolled, at least one bar for spraying a lubricating and/or cooling fluid, disposed near the plane of the strip to be rolled, a stand inside of which the rolls are arranged, at least one device for adjusting the inclination of the at least one bar comprising an actuator, such as a hydraulic cylinder configured to change the inclination of the bar around the pivot axis. The actuator of the device for adjusting the inclination is arranged, on the second side of the stand, opposite to the first side of the maintenance window.

A method for cold rolling rolled stock (2) in a mill train (1) with multiple roll stands (3 to 7). An upper limit temperature and/or a lower limit temperature is provided for a rolled stock temperature of the rolled stock (2) for at least one rolling pass, and the rolled stock temperature is controlled and/or regulated by at least one control or regulating measure such that during the at least one rolling pass, the rolled stock temperature does not exceed the upper limit temperature specified for the rolling pass and/or the rolled stock temperature does not fall below the lower limit temperature specified for the rolling pass.

Provided is a method for rolling a steel sheet and a method for manufacturing a steel sheet capable of preventing occurrence of defects in appearance of a steel sheet caused by oil spots of a coolant and preventing occurrence of defects in shape of a steel sheet by appropriately controlling thermal deformation of work rolls. The method for rolling a steel sheet according to the present invention is a method for rolling a steel sheet involving feeding of a coolant to rolls that form a rolling mill during the rolling. The method includes keeping a coolant feeding rate at or lower than a predetermined rate lower than an upper constant rate at a start of operation of the rolling mill, and increasing the coolant feeding rate to the upper constant rate in response to an amount of center buckles of the steel sheet reaching or exceeding an upper target value.

A wire block assembly cartridge for an arrangement of solenoid operated pilot valves for operating coolant control valves in a manifold assembly for supplying a pressurized coolant to a rolling mill and having multiple wire block blocks in the manifold. The cartridge has four coolant control valves and four solenoids coils that control the four coolant control valves, and four spray nozzles. The wire block assembly cartridge can have the spray nozzles on 25 mm centers to enable spraying in narrow zones.

A work roll cooling apparatus for a rolling mill includes: at least one chock (200) which is configured to support a work roll (100) in the rolling mill. The work roll (100) has an axis (X) about which it is rotatable. A shroud (300) so positioned adjacent the work roll rolling surface (100a) when the roll is in use to provide a cooling space within which a coolant is brought into contact with the work roll (100). The shroud includes a first part (301) disposed on the chock (200) to provide a predetermined gap (G) between the first part (301) and the work roll (100), a second part (302), and a connection for releasably connecting the first and second parts (301, 302). In a connected condition, the first and second parts (301, 302) are joined to provide the cooling space within the shroud (300), and in a disconnected condition, each of the at least one chock (200), the first part (301) of the shroud (300) and the work roll (100) may be axially removed from the rolling mill and the second part (301) of the shroud (300).
