Description

Technical Field

[0001] The utility model relates to the technical field of degassing devices, in particular to a degassing device for molten aluminum. Background Art

[0002] Liquid aluminum is generally produced by putting aluminum blocks into an aluminum melting furnace. When the aluminum blocks are melted into aluminum liquid, the hydrogen and non-metallic impurities in the aluminum liquid need to be removed first.
