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.
● 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
