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 […]

The molten aluminum ceramic filter plate can effectively remove the large inclusions in the molten aluminum, and absorb the fine inclusion particles of micrometer size, improve the surface quality, improve the product performance, improve the effect of the microstructure, and increase the yield. It is widely used in the production of aluminum profile, aluminum foil, […]

The liquid metal filter was developed in the 1970s. The liquid metal purification technology was first applied to aluminum alloys. Because the melting point of aluminum alloys is low, the density of alloys and oxides are close, and inclusions are difficult to float. Inclusions are the most common casting defect. In casting production, many process […]

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 […]

Aluminum liquid filtration generally uses foam ceramic filter filtration. When the aluminum liquid passes through the tortuous and interconnected pores in the foam ceramic, the internal debris is deposited on the wall of the pore under the action of fluid power, inertia, interception, collision, and adsorption. So that the clean aluminum liquid enters the casting […]

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 […]

Ceramic filter filtration is becoming more and more common because people have higher and higher requirements for the quality of aluminum products. The ceramic filter for casting can not only effectively remove a large number of oxide inclusions in molten aluminum, but also filter out a few microns of small inclusions which can not be […]
