Product Description
Ceramic Foam Filter (Silicon Carbide, Alumina, Zirconia, Magnesia)
Ceramic foam filter is just developed as a new type of molten metal filters to decrease casting flaw recently. 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.
Classification and Specifications:
*Alumina / Al2O3 Ceramic Foam Filter
It's mainly for filtration of aluminum and aluminum alloys in foundries
*Zirconia / ZrO2 Ceramic Foam Filter
It's used for molten all types of steels like unalloyed, low alloyed, stainless and high-alloyed as well as Nickel and Cobalt-based super-alloys
*Silicon Carbide/SiC Ceramic Foam Filter
It's mainly for filtration of cast iron (grey iron & ductile iron) and non-ferrous alloys
*MgO/Magnesia Ceramic Foam Filter
It's mainly for filtration of molten magnesium and its alloys
Advantages:
*High porosity
*Low loss of thermal shock
*High mechanical strength at normal and high temperature
*Large specific surface
*Good chemical stability
*Excellent filtering functions of screen
*Excellent filtering residua collection and absorption
