High Quality 10ppi 20ppi 30ppi Ceramic Foam Filter Alumina Silicon Carbide Zirconia Material
Ceramic foam filter is just developed as a new type of molten metal filters to decrease casting flaw in recent years. It is made from high quality ceramic materials, whose main components are Al2O3, Sic, ZrO2, MgO etc. Ceramic Foam Filter has the characters of light weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance and high temperature stability in molten metal. With the distributing pores net structure, they are able to increase the surface areas, and absorb the sinter, the liquid metal becomes more pure, waster quality problems such as sand pore and air pore are much less and the cast quality becomes much better.

1. Alumina Ceramic Foam Filter is applied to purge and filter solution of aluminium and aluminium alloys.
Alumina ceramic foam filter is a new type of low density, high porosity and with three dimensional network skeleton structure of the filter. And widely used in aluminum process industry for molten aluminum filtering, so as to improve aluminum quality. Alumina ceramic foam filter can effectively removes non-metal solid mixture from aluminium and aluminium alloy fusant, reduce trapped gas and provide laminar flow and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings,less scrap, and fewer inclusion defects, to improve the quality of aluminum alloy and other non-ferrous alloy casting, all of which contribute to reduce casting cost, its maximum service temperature 1200° C.
2. Silicon Carbide Ceramic Foam Filter is applied to purge and filter solution of ductile iron casting, grey iron and other iron casting.
Silicon carbide foam ceramic filter using German imported polyurethane foam sponge as a carrier, silicon carbide mainly squeezed into the foam sponge, and then squeeze out the slurry,the slurry around the foam fiber, after drying, baking at high temperature, polyurethane thermal decomposition, leaving foam ceramic products, namely silicon carbide foam ceramic filter.
The silicon carbide foam ceramic filter, with the three- dimensional mesh interconnection structure of foam sponge, can make metal liquid reflect rectification, mechanical screening, filtration cake, adsorption and other filtration mechanisms to effectively improve the purity of metal liquid, reduce waste rate, reduce mechanical processing loss, thus improve production efficiency and reduce production cost.
Silicon carbide foam ceramic filter has high strength, good thermal stability, larger than surface area and high size accuracy.
It is mainly used to filter and purify the filtration of ductile cast iron, ash cast iron,aluminum, copper and other alloy metal liquid, effectively remove large inclusions in metal liquid, adsorb smell magazines, reduce the content of gas and harmful elements in metal liquid, improve the metal matrix organization, and improve the mechanical properties of castings.
