With the continuous expansion of the application field of aluminum and aluminum alloy materials, it has begun to extend to various fields of industry. At the same time, recycled aluminum smelting technology, including alumina processing machines, has become more mature and is widely used in the processing of aluminum products. Among them, the so-called melting is actually to put a certain proportion of metal charge in the furnace, and then heated for processing, after which the melt can be obtained.

　　Then, these melts are adjusted to obtain the alloy liquid that meets the standard. As far as aluminum material is concerned, because of its characteristics, aluminum alloy is easy to produce oxidation inclusion in atmospheric environment.

　　Therefore, the problem that needs to be paid attention to in the whole process of aluminum alloy melting is how to prevent and remove the oxidation inclusion on the surface of these aluminum alloys.

In addition, in order to obtain high-quality aluminum alloy liquid in the entire smelting process, strict control is required from all aspects.

The entire smelting process includes loading, melting, slagging, stirring, sampling, composition adjustment, melt converter and refining.

Among them, as far as the loading process is concerned, attention should be paid to taking the correct loading method, only in this way can the burning loss of the metal be reduced, thus reducing the smelting time.
