Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aluminum alloy rod casting, in particular to an aluminum liquid cleaning device for aluminum alloy rod casting. BACKGROUND

[0002] Aluminum alloy rod is an alloy material synthesized by aluminum and other metal elements (such as copper, silicon, magnesium, manganese, zinc, etc.), which has good mechanical properties, corrosion resistance, lightweight characteristics and high strength, and is widely used in aerospace, automobile manufacturing, construction, mechanical equipment, electronic products and other industries.

[0003] During the casting of aluminum alloy rod, aluminum alloy raw materials (aluminum and alloy elements such as copper, silicon, magnesium, etc.) are first placed in a furnace and heated to a molten state. During the melting process, impurities such as oxides will be produced on the surface of the aluminum alloy, which need to be removed through a slag removal process to ensure the purity of the aluminum alloy. The molten aluminum alloy liquid is poured into a casting mold through a pouring mold. The pouring process needs to ensure uniform flow rate to avoid the generation of pores and inclusions. The aluminum alloy liquid cools and solidifies in the mold to form an aluminum alloy rod.

[0004] In the prior art, during the casting of aluminum alloy castings, aluminum liquid cleaning is an important step. In order to separate the impurities on the surface, a slag former is generally used to effectively separate the aluminum alloy castings and the impurities on the surface, and make the impurities form dross and float on the top of the aluminum liquid. At this time, the dross located on the top of the aluminum liquid needs to be captured to avoid adhering to the surface of the subsequent aluminum alloy castings. However, in actual dross capturing operation, it is mostly completed by manual capturing.
