Description

Technical Field

[0001] The utility model relates to the field of aluminum ingot casting production, in particular to a cooling device for aluminum ingot production. Background Art

[0002] In the process of preparing aluminum alloy materials, first, a melting furnace is used to melt aluminum blocks into aluminum liquid. The aluminum liquid is injected into an aluminum ingot mold cavity through an ingot casting machine for cooling and forming. Finally, the formed aluminum ingots are taken out of the mold and stacked into piles. The traditional cooling method is to set spray nozzles above the aluminum ingot mold for spray cooling. Such a cooling method will generate a large amount of water vapor. If the water vapor is not recovered in time, it will cause the temperature of the working area to rise, resulting in the equipment getting damp and increasing the risk of equipment damage.
