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 […]

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 […]

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 molten metal filtration has great advantages in reducing production costs and improving product quality. In addition, ceramic foam filters are used to purify molten aluminum. It is arranged horizontally in the CFF filter box, that is, between the launder and the casting well. Moreover, a ceramic foam filter plate can effectively filter […]

The pressure drop or alternative flow reduction caused by the Ceramic Filter for Aluminium Foundry is affected by the length of the Filters, the roughness of the filter and the effective filter area. The effect of filters on mold filling behavior has been evaluated by direct observation experiments. Direct observation is a very useful way […]

The ceramic filter for aluminum foundry is capable of filtering metal solution slag and metal impurities far better than other filters, and its filtration has a comprehensive physical and chemical effect. Large inclusions are physically screened and retained on the surface of the filter. Due to chemical affinity, small inclusions are adsorbed on the surface, […]

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 […]
