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.
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
