Alumina ceramic foam filters are specially developed by AdTech for molten Alu filtration. The molten aluminum flows through the tortuous and porous three-dimensional foam structure, and the tiny impurities are trapped, adsorbed, deposited, and firmly adhered to the pore walls, filtering out the micron-level impurities in the molten aluminum, and solving the aluminum alloy’s sensitivity […]

The alumina ceramic foam filter for casting can capture the inclusions according to a certain mechanism, thereby purifying the metal. In 1978, the United States developed a new filter-ceramic foam filter, which provides a high-efficiency filter for the production of aluminum castings, and is widely used in the production of semi-continuous ingots and molded castings. […]

Foundry molten metal filtration requires good chemical stability and excellent filter function, especially for the collection and absorption of 1~10um small impurities and filter residue. The ceramic foam filter has a three-dimensional structure, it can improve the quality of castings on a large scale by changing the molten metal from turbulent flow to laminar flow, […]

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 […]

According to the molten Al filtration method, the molten Al is passed through a refractory ceramic foam filter to remove inclusions. Larger inclusion particles can be removed from the molten Al. However, it is difficult to remove small inclusion particles of 100 μm or smaller that account for most of the inclusions. In particular, it […]

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 […]

Today’s aluminum industry requires strict metal quality standards to prevent parts failure in key components of automobiles, airplanes, and machinery. Filtration is the last online metal treatment performed before molten aluminum casting. To control the flow rate and reduce the level of inclusions entering the filter system, many other upstream processing stages are required, all […]

Ceramic foam filter is a particularly useful filter in the filtration of molten metal. Ceramic foam filter manufacturing process is simple, immers the polyurethane foam in the ceramic slurry, and fires the polyurethane foam. It can make porous, hard, self-sustaining ceramic foam filter products. Ceramic Foam Filter Manufacturing Process The flexible foam material is impregnated […]

Alumina CFF filtration is widely used in molten aluminum purification, ceramic foam filter is the most cost-effective filtration media. Alumina CFF Filtration 1. It can effectively eradicate large inclusions in molten aluminum. 2. It can remove small inclusions of a few micrometers in size that are incapable of conventional processes in molten aluminum. At the […]

The ceramic foam filter has a network pore structure, has a certain strength, can withstand the pressure difference of the metal liquid level and the impact of the metal flow, but it is brittle and fragile. Because this material has a precise structure, uniform quality, and has a great surface area, so the ceramic filter […]
