Light transmittance is an effective non-destructive testing method for aluminum cast ceramic filter plate products and filter area, and it is also another important indicator to measure product quality indicators. The higher the light transmittance, the fewer blind holes, and the more filter holes, the better the filter effect. All the light transmittances of the […]

For the production of high-end products, deep bed filtration is recommended for process configuration: degassing device + deep bed filtration device + cast ceramic filter. Cast Ceramic Filter filtration is used before casting to avoid media loss due to deep bed filtration, which causes too many inclusions to accompany molten aluminum casting, resulting in a […]

Ceramic foam filter is a commonly used filter tool in aluminum and non-ferrous alloy smelting industry. The foam filter is made of whiter high-purity alumina (Al2O3). The alumina ceramic foam filter provides deep filtration to remove a large amount of impurities in molten aluminum, and the mesh filter provides thorough deep filtration to remove impurities […]

Alumina ceramic foam filters are mainly used for filtering aluminum and aluminum alloy in casthouse. These filters are machined to tight dimensional tolerances, are treated during processing, and have very low friability. Filter the inclusions in the casting, reduce the gas in the casting, reduce the turbulence when filling the molten metal, reduce the surface […]

In recent years, ceramic foam filters molten metal filtration have been developed as a new type of filter to reduce casting defects. Foam ceramics have the characteristics of lightweight, high mechanical strength, large specific surface area, and high porosity. The molten metal has excellent thermal shock resistance, chemical corrosion resistance, and high-temperature stability. With the […]

The casthouse ceramic foam filter has the same inherent shape as the basic polyester open-cell foam, with high efficiency, open-cell and net-like structure, high porosity (over 90%) and large surface area to trap inclusions. The casthouse ceramic foam filter is made by impregnating the basic foam medium with ceramic slurry and firing at a very […]

Casting defects closely related to entrained bubbles and metal oxides occur very frequently during the casting process. Studies have shown that molten metal ceramic foam filters are added to the horizontal flow channel to prevent bubbles and reduce turbulence. The ceramic foam filter performs well in reducing the flow rate and stabilizing the water flow. […]

Ceramic foam filters have special applications in the filtration of molten metals, especially aluminum. In fact, molten metal, especially molten aluminum, often contains entrained solids, which are harmful to the final cast metal product. These entrained solids appear as inclusions in the final cast product after the molten metal is solidified, and cause the ductility […]

Ceramic foam filters are particularly useful for filtering molten metals, especially molten aluminum. The ceramic foam filter has the characteristics of high temperature resistance, and it does not pollute the metal in the molten metal filtration. Ceramic foam filters for molten metals are low-cost materials and can be conveniently used on a disposable basis. The […]
