Ceramic foam filter is a very good product, which is widely used in molten aluminum filtration in aluminum smelting and casting process to prevent particulate impurities in molten aluminum from entering the casting billet and affecting the quality of aluminum processed products. According to the quality requirements of the castings, the flow rate of the […]

Investment casting is the process of forming metal or metal alloy products (also called castings) by solidifying molten metal. Precision casting is an important method for producing high-quality precision casting metal products in various industries. Castings usually contain unwanted materials called “inclusions.” The generation of inclusions can be attributed to the slag or scum material […]

Regardless of the filter used, care must be taken to ensure that the filter is not affected by excessive vibration or changes in the metal level. These interferences will cause the release of inclusions, which may eventually lead to inclusions in the finished product. Good process control downstream of the final aluminum alloy filtration equipment […]

AdTech provides a high-efficiency ceramic foam material for filtering molten metal, especially molten aluminum. The ceramic foam material is characterized by having a three-dimensional network structure with a plurality of interconnected voids surrounded by the net of the ceramic material with ceramic fibers. The air permeability of the filter is 400 to 8000×10 -7 cm […]

Foam ceramic filter is the last technology for molten aluminum filtration. It is particularly important to choose the foam ceramic filter board. According to the environment of each foundry, choose the best ceramic foam filter and obtain high cleanliness of molten aluminum. The choice of foam ceramic filter plate depends on the impurity content in […]

Ceramic foam filter of aluminum is used to remove the oxide inclusions and provide high-quality molten aluminum for the casting process. Before the ceramic foam filter (CFF) filters the molten aluminum, it is necessary to fully preheat the ceramic sheet and the filter box to ensure that the molten aluminum can pass through the filter […]

In the late 1970s, the United States made a sponge-like ceramic foam filter (CFF) made of alumina and chromium oxide. CFF filter for molten aluminum not only has good purification technology, but also is easy to use. The initial pressure difference through the melt is only 100-150mm, and once it passes, it only needs to […]

Ceramic foam filter for molten metal filtration is used as a means of separating finely divided solid impurities suspended in the melt. For this purpose, it is recommended to use a refractory bed, compacted loose filter material block or screen. It has also been proposed that ceramic foam filter can be used as a filter […]

Porous Ceramic Filter Filtration can remove alumina and other nonmetallic compounds, such as lithium oxide from the molten aluminum lithium alloy. The porous ceramic filter may be a cellular structure or a foam with interconnect pores. As everyone knows, in order to remove alumina from molten aluminum or aluminum alloy, aluminum or aluminum alloy is […]

Cake filtration is the most common mechanism in which the foam ceramic foundry filters acts as a sieve and retains particles larger than its pore size on the surface of the filter. These retained particles then form a screen and capture particles smaller than the filter aperture. As the cake accumulates on the surface of […]
