As the third-generation filter equipment, ceramic foam filters for molten metal filtration are particularly widely used in metal smelting and casting production. Foam ceramic filters are used in the filtration and purification of molten metal, which has also promoted the rapid development of the domestic metal casting industry, and improved the yield, machining performance and […]

How to select molten metal filters? You need to understand which filter material is suitable for your metal casting and the characteristics of the filter. Foam ceramic is an ideal form of structure. The pore size and number of pores of this structure determine the resistance of the metal liquid through the filter. When non-metallic […]

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 […]

Alumina ceramic foam filters for casting are widely used in the production of aluminum profiles, aluminum foil, and aluminum alloys. The size is available in square, and custom geometric shapes; sizes ranging from 10mm up to 600mm, and thicknesses from 10-50mm. The most common porosities are 10ppi, 20ppi, 30ppi, 40ppi, 50ppi, 60ppi. 1.10-30ppi continuous casting […]

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 […]
