In order to obtain the best mold filling rate, it is important to calculate the appropriate ceramic foam filters size for each specific casting application. The filter must be large enough so that it will not obstruct or block the flow of molten metal or be blocked by residual inclusions before casting is complete. In […]

The initial foam ceramic filters manufacturing is formed by coating the reticulated polyurethane precursor with a ceramic slurry. The reticulated open-cell foam, preferably polyurethane foam, is impregnated with the ceramic slurry, wherein the entire structure of the reticulated open-cell foam is preferably covered by the slurry. The pore size of the foam is preferably between […]

The purification of molten metal plays an important role in improving the mechanical properties of castings. At present, the filtering device used to purify molten metal is mainly ceramic foam filter used for aluminium castings, which can effectively intercept harmful impurities in molten metal, convert molten metal from turbulent flow to laminar flow, and completely […]

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 […]

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 […]

The high temperature ceramic filter has a three-dimensional network skeleton structure, which is prepared by applying the ceramic slurry to a synthetic resin foam, it has an open-cell three-dimensional network skeleton structure, followed by drying and firing. The ceramic slurry contains 20-40 parts by weight of aluminum titanate, 40-60 parts by weight of mullite, 2-20 […]

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 […]
