  • Hybrid oil and water cooled rolling
    Patent number: 9925575
    Abstract: A rolling mill with oil-cooled top and bottom work rolls at the entry side and a water spray header at the exit side of the bottom work roll. Water cooling is used below the pass line, reducing the heat in the mill substantially without the risk of generating drip-related surface defects during rolling. Water cooling can be used on the bottom work roll and a portion of the oil no longer needed to cool the bottom work roll can be diverted to the top work roll. In some cases, the coolant portion of the flatness control can be operated solely through water-cooling the bottom roll.
    Type: Grant
