Description

Technical Field

[0001] The utility model relates to the technical field of aluminum liquid deslagging equipment, in particular to an aluminum liquid deslagging stirring head. Background Art

[0002] During the aluminum alloy smelting process, due to the diversity of raw materials and the influence of the smelting environment, various impurities such as oxides, silicates, metal inclusions, etc. are often mixed into the aluminum liquid. The presence of these impurities will seriously affect the performance of the aluminum alloy, such as reducing its strength, toughness, corrosion resistance, etc., and even causing the casting to be scrapped. The existing aluminum liquid slag removal process often requires stirring the aluminum liquid, but the existing equipment is often relatively simple, resulting in insufficient stirring of the aluminum liquid, and the aluminum slag often needs to be manually filtered out.

[0003] For example, Chinese patent announcement number CN203999756U discloses an aluminum liquid deslagging stirring head, comprising: a stirring rod, a stirring wheel, a connecting head and a stirring wheel frame, wherein a connecting head is arranged above the stirring rod, a stirring wheel frame is arranged at the lower end of the stirring rod, and the stirring wheel is arranged on the stirring wheel frame. In the above manner, the aluminum liquid deslagging stirring head of the utility model has the advantages of high reliability, compact structure, good stirring effect, convenient deslagging, low price, good adaptability, etc., and has a broad market prospect in the refined aluminum smelting industry.

[0004] Although the above technical solution can remove impurities in aluminum liquid, there are still the following problems in actual use:

[0005] (1) The stirring wheel is rotating all the time. When using it, stir it thoroughly first, then stop stirring and let it stand to remove the slag, so the slag removal time will be longer.

[0006] (2) When removing slag from molten aluminum, in order to effectively remove impurities in the molten aluminum, it is usually necessary to add additives such as slag removers or refining agents. These additives are added from the surface of the molten aluminum. The molten aluminum in the upper section first produces impurities. During stirring, these impurities hover in the upper section, affecting the penetration of the additives into the bottom of the molten aluminum, thus causing uneven slag removal.
