Product DescriptionFunctions of ceramic foam

systemImprove the metallurgical structure of the castingsReduce
imparities of the castingsImprove casting quality rateReduce
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. Physical and Chemical
