Ceramic Foam Filter Medium for Molten Aluminum

Seramik Köpük Filtre Malzemesi

Ceramic foam is a good example of a filter medium that is used as a depth filter from the beginning and as a cake filter at the end of its “service life”. The two-stage ceramic foam filter system uses two standard ceramic foam filters in series to provide higher filtration efficiency while retaining all the well-known advantages of ordinary CFF systems. These systems can be used for multiple casting processes (slabs, extruded billets, continuous casting, continuous bar casting machines) and various final products (rigid and flexible packaging, automotive condenser tubes, copier drums and wire rods).

The impurities in the melt have been identified as the main cause of product failure during production and use. Therefore, melt cleanliness becomes a measure of melt quality.

The source of impurities can be traced back to bulk metal, various melt processing operations, and the interaction of molten metal with refractory materials and the environment. Especially trying to determine the source of dissolved elements.

Refining methods such as degassing, flux, sedimentation, and filtration were reviewed, focusing on the possibility of removing dissolved elements. However, melt cleaning procedures, especially fluxes, are a potential source of impurities.

Bizim alumina ceramic foam filter uses high-quality foam and high-purity ceramics as raw materials, which can effectively remove the non-metallic solid mixture of molten aluminum and aluminum alloy flux in the aluminum casting industry.

Ceramic Foam Filter Medium Features

Uniform pore size, high porosity, correct sintering, high bending and compressive strength, and effective filtration.
It is widely used in continuous casting, semi-continuous casting, gravity casting and low pressure casting aluminum flux filter equipment.

The pore size of the alumina ceramic foam filter ranges from 20 to 60 ppi, with different sizes and shapes.

30 ppi ve 40 ppi Foundry Filtresi, alüminyum döküm endüstrisinde en yaygın olarak kullanılan seramik köpük filtredir.

Sıradan alüminyum dökümde genellikle 10-40 ppi seramik filtre plakaları kullanılır.

Havacılık sektöründe ve yüksek kaliteli alüminyum malzemelerde genellikle 30-60 ppi seramik filtre plakaları kullanılır.
