Liquid Aluminum Filtration
Molten aluminum in a melting furnace before further processing – casting into ingots or castings – almost always requires filtration. Filtration methods depend on the casting technology used or the method of processing aluminum melt. Generally considered, it is possible and beneficial only when working with large enough volumes of metal.
Filters can be used for large industries and in small foundries, including for filtering metal during the casting of each individual cast.

Alumina ceramic foam filters can authorize great to have the suitable components for topmost efficiency in the foundry and metallurgical industry. It can be increasing casting flexibility with easy alloy changes and reduce scrap related to inclusions.
Alumina ceramic foam filter is mainly applied to the aluminum and aluminum alloy fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting, also applied to other non-ferrous metal precision casting.
The use of the filtration process is mainly based on the following considerations. On the one hand, the filtration makes the flow of molten aluminum orderly and relatively calm, and on the other hand, the solid slag in the molten metal is effectively removed, and the quality of castings is rapidly improved.
Aluminum liquid often contains impurities and inclusions. Whether the aluminum liquid is handled well or not will directly affect the quality of the cast rod. In order to effectively remove the impurities in the molten aluminum, a ceramic foam filter is used as the medium for filtering the molten aluminum.
