Systems and methods directed to rolling mill coilers are disclosed. Systems and methods are disclosed for a control scheme to maintain a constant force between a roll and a coil's surface. Example systems and methods may include forming a portion of a coil, capturing a first coil data corresponding to force of the coil while the strip of metal is being rolled into the coil, capturing second coil data corresponding to position of the coil while the strip of metal is being rolled into the coil, determining a signal that corresponds to a roll force of the roll and a position of the protrusion, and transmitting the signal to a hydraulic cylinder coupled to the roll, the hydraulic cylinder causing the roll to exert the roll force counter to the radial force of the coil.

Sensing and offsetting the force of events in a coil forming operation

A rolling mill control system and method includes use of sensors located between rolling mill stands to directly measure metal sheet or plate flatness, thickness profile, position, and the camber of the rolls in the mill. A feedback loop control system adjusts or adapts rolling mill control mechanisms to control the rolling process.

Method and apparatus for controlling metal strip profile during rolling with direct measurement of process parameters

Provided herein are systems and methods for containing a viscous material, such as a coolant, on a roll and/or a roll processed engineering material (e.g., a metal strip). In particular, a viscous material containment system can include a movable seal and a gas delivery device. A method for cooling a roll can include applying a viscous material, such as a coolant, to the roll and containing the viscous material on the roll using the viscous material containment system. In some cases, the viscous material containment system can be used to facilitate removal of the viscous material from the roll and/or the roll processed engineering material.

Systems and methods for containing viscous materials in roll processing

Provided herein are systems and methods for containing a viscous material, such as coolant, applied to cool a roll or a roll processed engineering material such as a metal strip. In particular, a viscous material containment system can include a housing, a viscous material delivery system, a plurality of movable seals and a plurality of gas delivery devices. A method for cooling a roll can include applying a vicious material, such as coolant, to the roll and containing the viscous material on the roll using the viscous material containment system. In some cases, the viscous material containment system can be used to facilitate removal of the viscous material from the roll.

Systems and methods for cooling a roll in metal processing

A rolling mill apparatus and methods of hot rolling with targeted cooling. In one aspect, a mill having multiple roller stacks includes a cooling system that directs the bulk coolant flow to a heat exchanger having first and second heat exchangers in parallel. The first heat exchanger is adapted to cool the heated coolant to a first temperature for use in a first coolant stream discharged through a first set of nozzles during rolling, while the second heat exchanger is adapted to cool heated coolant to a lower temperature for use in a second coolant stream at a second temperature lower than the first for discharge through a second set of nozzles downstream to facilitate rolling or coiling of the rolled metal.
