Ceramic Foam Filters Sizing To obtain an optimum mold fill rate, it is important to calculate the proper filter size for each specific casting application. The filter must be large enough so that it doesn't retard or choke the flow of molten metal or become blocked...
Why Ceramic Foam Filters? Filtration with ceramic foam filters offers several key benefits that improve the quality of premium aluminum castings. These include: * improved mechanical properties; * reduced dye-penetrant indications; * reduced x-ray evidence of nonmetallics; * reduced rework/scrap; * improved machining properties. The presence of nonmetallic inclusions is detrimental to...
Foundry Ceramic Foam Filter Drache offers SiC filters in all common sizes starting from 1.5×1.5×0.5” up to 26x26x2” and 28x24x2”. Filters sized 6×6” and larger are recommended to be used in thickness 1.25” or 2”instead of the common thickness of 7/8”. 1.25” thick filters have the...
Ceramic Foam Filter Manufacturing Process Ceramic foam filter is manufactured in several different ways. The polymeric-sponge method produces open-cell structures by impregnating a polymeric sponge with a ceramic slurry, which is then burned out to leave a porous ceramic filter. In order to create a honeycomb...
Launder Pre-Heaters Launders and heated launder covers provide considerable energy savings and are safe to work around. The Adtech Materials’ heated cover system provides the cast house with a means to accurately pre-heat the launder system to virtually “steady state” condition. The refractory is preheated to the...
Alumina Ceramic Foam Filter Introduction Introduction Alumina Ceramic Foam Filter is a special technology. Divided into two shapes: round specifications, square specifications and weaving way: honeycomb. It has a foam-like porous structure of ceramic products, and its light weight, chemical stability, large surface area through-hole rate, corrosion...
Aluminium Smelting and Refining Process Overview Bauxite is extracted by open-pit mining. The richer ores are used as mined. The lower grade ores may be beneficiated by crushing and washing to remove clay and silica waste. The production of the metal comprises two basic steps: Refining. Production of...
