Description

Slag taking device for molten aluminum refining deslagging equipment

Technical Field

The utility model relates to a technical field of aluminium liquid refining equipment, in particular to a get sediment device for aluminium liquid refining slagging-off equipment.

Background

During the smelting process of cast aluminum alloy, a large amount of hydrogen and impurities exist in aluminum liquid. When the aluminum liquid is solidified at 660 ℃, the solubility of hydrogen is rapidly reduced, the hydrogen cannot escape from the solidified aluminum due to high cooling speed and remains in the casting, finally, casting defects such as pinholes, porosity and the like are formed, and impurities remaining in the aluminum directly influence the connection strength between all areas in the casting. Therefore, when a cast aluminum alloy melt is subjected to a cleaning treatment (also called refining), it is necessary to remove gas and inclusions from the melt.

The existing aluminum liquid refining degassing and deslagging device is represented by a box type degassing machine, which breaks up large bubbles of inert gas into very fine small bubbles through a rotor which rotates at a high speed and sprays the inert gas, and the small bubbles are uniformly dispersed in aluminum liquid. By reducing the bubble diameter, the total surface area of the bubbles increases dramatically, which brings more inert bubble surfaces into contact with the hydrogen and impurities in the aluminum melt, thereby bringing the hydrogen and impurities to the melt surface.
