  • METHOD AND EQUIPMENT FOR COOLING ON A REVERSING HOT ROLLING MILL
    Publication number: 20230219125
    Abstract: The invention relates to a hot reversing mill equipped with one or more cooling systems consisting of bars of nozzles spraying an aluminum blank. It also relates to the hot rolling process associated with this hot reversing mill wherein the cooling system serves at least once making it possible to produce aluminum sheets advantageously. It also relates to the process for rolling an AA6xxx series aluminum alloy wherein a blank is cooled during the hot rolling and a sheet obtained with this process. The invention makes it possible to enhance the productivity of reversing mills by enhancing the metallurgical quality and/or the productivity of the other fabrication steps. The invention is particularly useful for providing superior quality 6xxx alloy sheets intended for the automotive industry.
