Ceramic foam filter is the third generation of filter material after fiberglass mesh, honeycomb ceramic filter. With its three-dimensional structure, it has excellent filtering functions of screen, filtering, residuum collection and adsorption in filtering molten metal liquid. It has good chemical stability and does not react with alloy liquid, effectively remove the inclusion in the metal liquidto improve the purity of molten metal. It can make casting surface smooth, increasestrength,reduce the rejection rate, and reduce energy consumption, improve labor productivity, reduce costs. The ceramic foam filter is not onlyappliedfor metal filtering in high temperature, but high temperature gas treatment, carrier of catalyzer , solid heat exchanger and special filling for chemical industry.
Ceramic Foam Filter Features: 1Mechanical block: remove large non-metallic inclusions. 2Filtering effect: filter small non-metallic inclusions. 3Deep adherence: adhere little inclusions. 4Reduce turbulence, provide laminar flow, avoid whirlpool. 5Trap gas that enter the mold cavity, relax impact, and decrease drop sand. 6Effectively enhance qualification rate. 7Improve metallurgical structure of metal products 8Enhance mechanical properties of metal products 9Simplify gating system
SEFU ceramic foam filters are available in three materials: silicon carbide ceramic foam filter, used for grey iron, ductile iron, copper, bronze, brass and investment casting; Alumina ceramic foam filter, used for aluminum and aluminum alloys casting; Zirconia ceramic foam filter, used for carbon steel, stainless steels casting.
Ceramic foam filter size: The size are available in square, round and custom geometric shapes; sizes ranging from 10mm up to 500mm, and thicknesses from 10-50mm. The most common porosities are 10ppi,15ppi, 20ppi, 30ppi,40ppi,50ppi. Higher porosities are available upon request. Custom-made cut-to-size filters are also possible.
