Mgo Ceramic Foam Filter 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..
Functions of ceramic foam filter: *Decontaminate the melting metal liquid; *Simplified gatingsystem
Improve the metallurgical structure of the castings; *Reduce slag inclusions of the casting; *Increase the casting quality rate; *Reduce casting internal re-oxidation defects; *Reduce the surface defects after matching of the castings.
