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

Systems and methods for using full-width hot sprays to pre-heat rolling mills prior to processing of metal sheet or plate are described herein. The hot sprays may be individually controlled. Using hot sprays can allow the rolling mill to reach operating temperature and achieve a desired thermal crown so that metal sheet or plate may be processed immediately within tolerances for flatness and gauge accuracy. Pre-heating of rolling mills can eliminate the need of the rolling mill to operate in a transitional period of work roll heating and can increase efficiency by eliminating or reducing scrap material and mill downtime. Hot sprays may also be incorporated with existing coolant systems to provide thermal control systems for rolling mills with bi-directional temperature controls.

Pre-heating and thermal control of work rolls in metal rolling processes and control systems thereof

A closed loop temperature control system for use in tandem rolling mills. The closed loop temperature control system uses dynamic information about the temperature of the material moving through the mill to adjust the work rolls to adjust the amount of thickness reduction between the stands to control the temperature of the material as it moves through the mill. In one embodiment, the control system is configured to eliminate or reduce temperature differences across the length of the material as the material moves through acceleration, steady state, and deceleration stages of the rolling process.
