CeramSource, Inc. offers a complete line of TaoFil ® ceramic foam filters for different kinds of metallurgical applications. The reticular shape of the foam filter provides a thorough and deep filtration to remove impurities in molten metal stream. ToaFil ceramic foam filters have excellent ability to resist high thermal shock while maintaining efficient filtration. They are widely used in sand, investment, shell and permanent molds for both ferrous and non-ferrous alloy filtration operations. Typical applications of TaoFil foam filters are categorized as follows:
TaoFil FCF-1: for steel cast industry -Temperature: 3000 °F
TaoFil FCF-2: for iron cast industry -Temperature: 2700 °F
TaoFil FCF-3: for non-ferrous alloy and aluminum industry -Temperature: 2000 °F
In order to get a good quality product, removing the inclusion becomes necessary. Liquid metal filtration through a ceramic media is an efficient way to clean the metal. Different types of ceramic media are used in-line in foundries, such as, ceramic foam filters, porous tube filters, bonded ceramic filters, and deep bed filters. (Wiki)
TaoFil® Ceramic Foam Filters FCF-1
TaoFil® FCF-1 foam filter is the most powerful and effective filtration technology to ensure high quality castings for molten metal industry. TaoFil® FCF-1 foam filters are made from zironcia- toughened alumina (AI2O3). TaoFil® FCF-1 foam filter is cream in color with no chemical binders. It has strong resistance against thermal shock and has proven effective at pouring temperatures up to 3000°F. Typical application of TaoFil® FCF-1 foam filter is for in-mold, tundish, pouring cup or baffle-type filtration.
TaoFil® Ceramic Foam Filters FCF-2
TaoFil® FCF-2 foam filter is an economical solution to achieve effective molten metal filtration. Silicon carbide ( SiC) is used as a distinctive element in the refractory mixture material to make TaoFil® FCF-2 foam filters. Gray in color, TaoFil® FCF-2 foam filter is a strong and durable foam filter, which can be used very effectively at pouring temperatures up to 2700 °F for gray & ductile iron casting applications.
TaoFil® Ceramic Foam Filters FCF-3
TaoFil® FCF-3 foam filter is a common type of filtering tool for aluminum and non-ferrous alloy smelting industries. White in color, TaoFil® FCF-3 foam filter is made from high purity alumina (AI2O3). This kind of filter works at pouring temperatures up to 2000 °F by providing a deep bed filtration to remove large amount of impurities from aluminum melt while the reticular shape of the filter provides a thorough and deep filtration to remove impurities in molten aluminum or non-ferrous alloy stream. It has excellent ability to resist high thermal shock while maintaining efficient removal of impurities with continuous and thorough filtration.
