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 […]

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 […]

Ceramic foam can be divided into two categories, namely, open hole (net) ceramic material and closed-cell ceramic material, depending on whether each hole has a solid wall. If the foam solid is only included in the hole, it is called an open hole ceramic material whose pores are interconnected. If there is a wall surface, […]

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 […]

30 PPI foam filter is suitable for aluminum alloy castings. The choice of ceramic foam filter is very important for a good filtration effect and no pollution to the alloy. Many practices show that the use of ceramic foam filters can remove inclusions, improve the structure of castings, improve the mechanical properties and qualified rate […]

Molten aluminum filtering with ceramic foam filter is the most effective way to remove nonmetallic slag from molten aluminum. In aluminum alloy casting, multilayer glass cloth filters or ceramic foam filters are usually used. No matter which molten aluminum filtering method is adopted, in order to ensure the normal molten aluminum filtration, the surface scum […]

CFF Filter Media is the final filtration step. This is a single-use disposable filter with a strictly controlled pore size. Due to their simple operation and good short-term results, these are usually the only filtration equipment in many foundries. The three key parameters of CFF filter media are: Filter area: the larger the area, the […]
