For industrial foundries, it is necessary to achieve the desired aluminum casting rate and the lowest acceptable filtration efficiency.<br \/>\nThe 10-20ppi filter has poor particle retention capacity, and is often used to filter the intercepted particles, surface oxides and other large particles generated during melting, storage and transportation.<br \/>\nHigh pore density filters with 60-80 ppi are only suitable for quality-sensitive applications, such as critical surface extrusion and thin-sheet products.<\/p>\n<p><strong>The structure of CFF creates a unique, tortuous fluid flow path that captures inclusions and allows for clean, smooth travel of the metal outlet to the mold cavity.<\/strong><br \/>\nThe most important filter parameters are effective porosity (that is, porosity, which effectively causes fluid), tortuosity, specific surface area and pore size.<br \/>\nThe filtration process also depends on: alloy type, refiner, pouring rate, metal temperature, etc.<br \/>\nThe addition of the refiner before the filter has a particularly negative impact on the filtration efficiency.<br \/>\nBased on cost, ease of use and acceptable performance characteristics, CFF is generally considered to be the &#8220;best&#8221; filter for casting.<br \/>\nTheir main advantages are: high filtration efficiency, reduced turbulence, refractoriness and corrosion resistance, suitable for the most demanding casting applications.<br \/>\nDeep-bed particle filters generally have better filtration performance, but they are more difficult and expensive to operate.<\/p>\n<p>The chemical composition of Ceramic Foam Filters is mainly alumina, and the porosity of the filter is about<strong> 85-90%.<\/strong> The density of ceramic particles is 3.48+0.02 g\/cm.<\/p>\n<p>Permeability is an important parameter for <a href=\"http:\/\/www.adtechamm.com\/es\/molten-metal-cff\/\">CFF<\/a> characterization because it needs to predict the flow rate that can be obtained at a given pressure drop, or to be able to predict the pressure drop required to reach a specific flow rate.<br \/>\nThe relationship between these quantities can be expressed as a function of fluid flow and media properties, and is obtained by fitting the permeability equation.<\/p>\n<p><img class=\"alignnone size-full wp-image-8540\" src=\"http:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/03\/Ceramic-Foam-Filters.jpg\" alt=\"Filtros de espuma cer\u00e1mica\" width=\"1024\" height=\"683\" srcset=\"https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/03\/Ceramic-Foam-Filters.jpg 1024w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/03\/Ceramic-Foam-Filters-300x200.jpg 300w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/03\/Ceramic-Foam-Filters-768x512.jpg 768w, https:\/\/www.adtechamm.com\/wp-content\/uploads\/2021\/03\/Ceramic-Foam-Filters-700x467.jpg 700w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/p>","protected":false},"excerpt":{"rendered":"<p>Ceramic Foam Filters range in size from 10 to 80 ppi.
