Abstract
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.
