MANUFACTURING METHODS AND APPARATUS FOR TARGETED COOLING IN HOT METAL ROLLING |
摘要 |
A rolling mill apparatus and methods of hot rolling with targeted cooling. In one aspect, a mill having multiple roller stacks includes a cooling system that directs the bulk coolant flow to a heat exchanger having first and second heat exchangers in parallel. The first heat exchanger is adapted to cool the heated coolant to a first temperature for use in a first coolant stream discharged through a first set of nozzles during rolling, while the second heat exchanger is adapted to cool heated coolant to a lower temperature for use in a second coolant stream at a second temperature lower than the first for discharge through a second set of nozzles downstream to facilitate rolling or coiling of the rolled metal. |
