Description

Technical Field

[0001] The utility model relates to the technical field of metal refining, in particular to a metal refining degassing and deslagging device. Background Art

[0002] Nonferrous metals need to be degassed and deslaged during production. During the smelting process of cast aluminum alloy, a large amount of hydrogen will exist in the aluminum liquid. When the aluminum liquid solidifies at 660°C, the solubility of the hydrogen will drop sharply. Due to the fast cooling rate, the hydrogen cannot escape from the solidified aluminum, but remains in the casting, eventually forming pinholes, looseness and other casting defects. Therefore, when purifying the cast aluminum alloy melt (also known as refining), the gas and inclusions in the melt must be removed.

[0003] The prior art discloses a device for refining, degassing and deslagging aluminum liquid (publication number: CN209778965U), which includes a rotating arm, a connecting rod and a baffle arranged at one end of the rotating arm, a refining cylinder and a powder spraying pipe arranged on the side of the rotating arm, and a heat insulation plate is provided on the lower surface of the rotating arm facing one end of the connecting rod, and the outlet of the powder spraying pipe is arranged next to the connecting rod, and a spiral blade is provided on the connecting rod.
