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.

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.

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 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).

A rolling mill with oil-cooled top and bottom work rolls at the entry side and a water spray header at the exit side of the bottom work roll. Water cooling is used below the pass line, reducing the heat in the mill substantially without the risk of generating drip-related surface defects during rolling. Water cooling can be used on the bottom work roll and a portion of the oil no longer needed to cool the bottom work roll can be diverted to the top work roll. In some cases, the coolant portion of the flatness control can be operated solely through water-cooling the bottom roll.

A device for cooling a roll for rolling materials, including a cooling shell opposite a sub-region of the roll surface circumference, for forming a cooling gap, through which a cooling fluid can flow, between the sub-region and the cooling shell. The device further includes a first lever which can be pivoted about a suspension point, which can be pivoted toward the roll surface, and which is rotatably connected to a first end region of the cooling shell, when viewed in the circumferential direction of the roll, and a second lever which can be pivoted about another suspension point, which can be pivoted toward the roll surface, and which is rotatably connected to the second end region of the cooling shell, when viewed in the circumferential direction of the roll, such that the cooling gap can be selectively reduced or increased by pivoting the levers.

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 method for rolling rolling stock, wherein a water-based cooling lubricant is applied to the rolling stock and/or to at least one roller which forms a roll gap, at least one water-soluble and tribologically active additive being added to the water-based cooling lubricant prior to application to the rolling stock and/or to the at least one roller.

Disclosed is a rolling mill including a frame, at least one pair of working cylinders capable of defining the air gap of the strip to be rolled, as well at least one line for spraying a lubricant and/or coolant fluid, arranged next to the plane of the strip to be rolled. The line is rigidly connected to the frame via a hinged mechanical link, the mechanical link including a resilient unit forcing the line into at least one operational position, toward the plane of the strip, and allowing, in the event that a force on the line tends to separate the line, greater than a threshold value, the deformation of the resilient unit against the return force thereof, and thus the retraction of the line toward a position separated from the at least one operational position.

The application is directed to a device (1, 1) for cooling a roll (2), in particular a working roll (2) for rolling rolling stock (3), wherein the device comprises a cooling shell (50, 60) which lies opposite at least one part region of the circumference of the roll surface for forming a cooling gap (5) between the part region of the roll surface and the cooling shell (50, 60), through which cooling gap (5) cooling fluid can flow, and a lever (40, 44) which can be pivoted about a suspension point (8, 48), can be pivoted in the direction of the roll surface and is connected rotatably to a first half (51, 61) of the cooling shell (50, 60) as viewed in the circumferential direction (U) of the roll (2), wherein the cooling gap (5) can optionally be reduced in size or enlarged by pivoting of the lever (40, 44). Furthermore, the device according to the invention comprises a variable-length linear guide (0, 99) which can be pivoted about a further suspension point (88, 48) and is connected rotatably to the second half (59, 69) of the cooling shell (50, 60) as viewed in the circumferential direction (U) of the roll (2).
