Abstract
One or more spray bars having a plurality of spray nozzles for cooling a rolling mill roll are provided with an apparatus to cause at least one spray bar to undergo a translational, rotational, and/or pivotal movement sufficient to change the spray-angle and/or spray-distance affected by nozzles thereon to thereby control the cooling rate effected by the nozzles so moved. The spray bar can be automatically controlled by providing a means for monitoring the roll condition and/or workpiece condition and means responsive thereto for moving the spray bar as necessary to change and adjust individual cooling rates effected by the nozzles and correct for any undesired result so monitored. A unique spray bar has nozzles arranged in a curved alignment so that each effects a different spray-angle and/or spray-distance. Like apparatus and comparable methods can be utilized to cool a hot rolled product.
