Ceramic Foam Filter

The ceramic foam material is made by impregnating an aqueous slurry on the struts of a flexible open-cell polymer foam precursor. The subsequent drying and firing of the material produces the final ceramic foam filter product. The foam precursor may be any type of material that has sufficient resilience to restore its original shape after […]

A filter for use in the filtration of molten metals comprises a ceramic foam filter with gasket made from fibrous material surrounding its peripheral surface. Due to dimensional variations in ceramic foam filters of a particular nominal size, and in the case of filtration of molten metal in a permanent mold or die due to […]

Open-pore ceramic foam filters for use in aluminum cast houses were developed in the early 1970s with the first commercial application of the technology in 1974 to produce rolling ingots for fabrication into plate and sheet materials. Open-pore ceramic foam filters are monolithic, one-shot or disposable, filters that are used for a single cast. Filter […]

AdTech provides an advanced alumina ceramic foam filter for molten Al filtering, it has an improved efficiency of removing especially fine inclusions of about 10 to 25 μm. Ceramic foam filters are widely used for molten aluminum filtration in primary and secondary aluminum foundries, they are also applied as filtering media in gas-liquid and liquid-solid […]

According to the molten Al filtering method, the molten Al is allowed to pass through a refractory filter to remove the inclusions therefrom. It is possible to remove relatively large particles of inclusions from the molten Al. However, there is a difficult in removing small inclusion particles of 100 μm or less, which account for […]

Before further processing (casting into ingots or castings), the aluminum melt is melted and then almost always requires filtering. The filtering method depends on the casting technique used or the processing method of the aluminum melt. It is generally believed that it is possible and beneficial only when a sufficiently large amount of metal is […]

The filtering efficiency of ceramic foam molten Al filters to remove inclusions from molten aluminum mainly depends on the roughness of the openings formed in the aggregated mesh member and the configuration of the mesh member. Therefore, particularly in order to remove fine inclusion particles of about 10 to 25 μm, the aggregated mesh member […]

The China ceramic filters supplier provides the CFF installed on the CFF BOX machine to filter the liquid impurities in the aluminum alloy, which can meet the high value-added, high-tech performance of aviation, transportation and other aluminum alloy precision casting production. China ceramic filters use a three-dimensional network structure in which organic foam is connected […]

Ceramic filter for molten Al can remove non-metallic inclusions in aluminum alloy melt. Treat with flux in the furnace. Ceramic foam filtration technology outside the furnace has become an important method for purifying molten aluminum. Ceramic foam filter is specially designed to produce high-quality cast products in aluminum casting workshops. It can reduce waste caused […]

The degassing and CFF filtering method is important for aluminum casting. It is a method of processing molten aluminum and aluminum alloys to remove solid and gaseous impurities therefrom. The molten metal flows through a series of successively arranged degassing and filtering stages. The ceramic foam refractory filter media filters molten metal to remove finer […]
