Regarding foam ceramic filter products, the development began in the 1970s. After more than 30 years of rapid development, the materials of the products are silicon carbide, zirconia, alumina, graphite, etc.; application areas include casting Steel, cast iron, cast aluminum, cast copper filtration. The ceramic foam filter can greatly improve the surface quality and performance […]

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 […]

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 […]

Ceramic foam filter is a very good product, which is widely used in molten aluminum filtration in aluminum smelting and casting process to prevent particulate impurities in molten aluminum from entering the casting billet and affecting the quality of aluminum processed products. According to the quality requirements of the castings, the flow rate of the […]

The final molten aluminum filtration step is usually a ceramic foam filter (CFF). This is a single-use disposable filter made of hard porous ceramic foam with strictly controlled pore size. Due to their simple operation and short-term good results, these are usually the only filtration equipment in many foundries. The three key parameters of CFF […]

Asian foundry filter agent has been authorized by China’s manufacturers to sell foam ceramic filters to local aluminum plants. The purification purpose of ceramic foam filter in aluminum foundry is to remove alumina slag and hydrogen from aluminum melt to improve the process and mechanical properties of aluminum materials or products. In the process of […]
