Narrow Zone Pilot Controlled Liquid Actuated Coolant Control Valve
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.
Working roller for a rolling mill for laminating a sheet of alkali metal or alloy thereof into a film
A working roller for a rolling mill for laminating a sheet of alkali metal or alloy thereof into a film is disclosed. The working roller has a cylindrical center portion defining a central axis, the center portion having an outer surface defining a lamination surface; and first and second frustoconical portions extending from first and second ends of the center portion respectively. When the central axis is straight, an angle between the outer surface of the center portion and an outer surface of each of the first and second frustoconical portions is less than 0.05 degrees. A width of the center portion is greater than a width of each of the first and second frustoconical portions. The width of the center portion is less than a sum of the widths of the first and second portions. A rolling mill having two such working rollers is also disclosed.

Rolling of a rolled material
The invention relates to a method and a rolling device for rolling a rolled material. The rolled material is guided through a roll gap between two working rollers of a reversing roll stand, alternatingly in two opposing rolling directions. A lubricant for lubricating a contact zone is introduced into the contact zone in which the rolled material is in contact with the working rollers, and a coolant is applied to the rolled material and/or the working rollers. In a mixture with a carrier gas, the lubricant is sprayed onto the working rollers and/or onto the rolled material exclusively on an outlet side of a pass. The coolant is applied to the working rollers and/or to the rolled material exclusively on an inlet side of a pass.
Lubricating device for applying a lubricant when rolling a rolling material
A lubrication device (1) for applying a lubricant when rolling a rolling material. The lubrication device (1) includes an extruded profile (3), through which run lubricant ducts (41) and at least one carrier medium duct (42), at least one connection block (5, 6) and nozzles (7). The connection block (5, 6) is connected to the extruded profile (3) and has lubricant connection ducts (54) that are each connected to one lubricant duct (41) of the extruded profile (3). The nozzles (7) are connected to the extruded profile (3) and are designed to create and emit a lubricant-carrier medium mixture consisting of lubricant and a carrier medium.

Rolling mill with cooling or lubricating device
Disclosed is a rolling mill including: a stand; two working rolls, two support rolls, and two intermediate rolls; lateral support rolls, able to support the working rolls laterally, each lateral support roll being borne by a support arm, mounted with the ability to pivot; load spreading beams and a mechanism for applying a preload on each support arm, including at least one preload actuating cylinder; one or more spray nozzles for a lubricating/cooling fluid, and wherein at least one of the nozzles, is carried on one of the support arms and in which the fluid supply circuit for the at least one nozzle comprises a device for connection/disconnection with the support arm with actuator. The actuator is an actuator distinct from the actuating cylinder of the mechanism for applying a preload.
Method for preparing ultrafine-grained superalloy bar
A method for preparing an ultrafine-grained superalloy bar, the method including: 1) designing a rolling machine including two rollers and two guide plates, where each of the two rollers includes a first roller and a second roller; the first roller includes a first curve and the second roller includes a second curve; the first curve and the second curve form a generatrix of the two rollers; 2) disposing the two guide plates with two curved surfaces thereof opposite to each other; disposing the two rollers to be between the two guide plates; where the two rollers and the two guide plates form a deformation zone of the rolling machine; and 3) driving the two rollers to rotate around their central axes, heating and introducing a superalloy blank from a gap between two first rollers to the deformation zone of the rolling machine; advancing the superalloy blank towards two second rollers.
