Reversing Mill Cooling Layout for Aluminum Blank Overheating

The patent applies preliminary cooling action by introducing cooling devices that cool the metal blank before it enters the rolling zone. This preliminary cooling prevents the metal from overheating during high-load rolling operations, enabling the mill to operate at higher capacities while maintaining temperature control. The cooling is performed in advance to prepare the metal for the demanding rolling process.

The patent introduces cooling fluid as an intermediary substance between the metal blank and the rolling environment. This cooling fluid acts as a heat transfer medium that absorbs excess heat from the metal during rolling, enabling higher rolling loads to be applied without causing overheating. The cooling fluid mediates the thermal interaction between the metal and its surroundings.

The patent applies local quality by using selective cooling zones with different cooling intensities. The cooling devices are arranged to provide stronger cooling in the bulk material regions while using milder cooling or no cooling in the surface regions. This localized approach allows rapid cooling of the interior to control temperature and enhance productivity, while preserving the surface quality and mechanical properties through gentler treatment of the outer layers.

The patent applies partial cooling action by targeting specific regions of the metal blank for cooling while leaving other regions, particularly the surfaces, with reduced or no cooling. This partial application of cooling enables the interior to be cooled rapidly for temperature control and productivity enhancement, while the surfaces maintain their quality through less aggressive cooling treatment.

The patent moves the cooling action from post-rolling (in tandem mills) to pre-rolling, by installing cooling devices in the reversing mill that cool the metal blank before and during the rolling process. This preliminary cooling enables the reversing mill to handle higher rolling loads without overheating, directly enhancing reversing mill productivity while maintaining improved temperature control capability.

The patent introduces cooling fluid as an intermediary in the reversing mill rolling process itself, rather than relying solely on post-rolling cooling in tandem mills. This cooling fluid mediates heat removal during the high-load rolling operations, enabling higher productivity in the reversing mill while maintaining temperature control, thus breaking the productivity bottleneck.
