Functions of ceramic foam filter
Decontaminate the melting metal liquid
Simplified gating system
Improve the metallurgical structure of the castings
Reduce imparities of the castings
Improve casting quality rate
Reduce casting internal re-oxidation defects
Reduce the surface defects after machining of the castings
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. 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.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.2.Alumina ceramic foam filter is mainly applied to the aluminum and aluminum alloys fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting, also applied to other non-ferrous metal precision casting, gas-solid and liquid-solid separation medium, high temperature gas filter, chemical filling, sound absorbing material and catalysis carrier etc.
3 Zirconia Foam Ceramic Filter:
Adjust the metal flow rate through rectification to reduce secondary inclusion and pores.
Reduce casting inclusion and reduce casting waste and welding repair rate.
Improve the surface quality and mechanical properties of the castings. Application of Zirconia Foam Ceramic Filter: Filtration of stainless steel, carbon steel and large castings.
