Ceramic foam filter is been made by specific procedures and have peculiar bone-frame holes just like the shape of foam(called three-dimensional connected channel) and myriad eyelets which only been found in big times microscope. Compare to similar ones, our products have many advantages as below:
Stable chemical composition
Excellent strength
Resistant to high temperature
Calm down of the turbulent flow of metal nicely
Big m2/m3
Superior dimensional tolerances: +0/-2.5
Suggestions:
A. Control the melting point satisfactorily. Especially high temperature will destroy it's function.
B. Suitable ppi for different casting materials.
C. Use the maximum temperature as soon as possibly.
D. The pouring highness don't exceed 20cm commonly, and metal liquid don't touch the filtration directly.
Materail: mullite. Mullite ceramic honeycomb filter have straight holes, more strongth compare to ceramic foam filter. Apply to iron, copper, copper, steel, stainless steel foundry.
Function:
1. Can remove big oxide,
2. Calm down turbulent laminar flow,
3. Absorb smaller impurities with it's myriad eyelets whicn only been found in microscope

Vacuum ceramic filter is a new type of solid-liquid separation machine which is featured in energy-saving, high efficiency, low production cost, high automation level, smooth operation, low power consumption, low moisture of filter cake, low suspended solid and appears in the 1980s. It¡¯s extensively used for solid-liquid separation in such industries as ore beneficiation, metallurgy, petro-chemicals, paper making, coal, environmental protection and so on.
Working principle: under the effects of pressure difference, as the slurry penetrates filter media, particles are blocked at the surface of filter media and filter cake is formed while liquid goes through the media and drained away so as to separate solid from liquid.
Vacuum ceramic disc filters are the solid-liquid separation equipment, used to dewater mineral concentrates and
Silicon Carbide Ceramic Foam Filter
Silicon Carbide Ceramic Foam Filter is mainly made of high purity fine silicon carbide powder, which is suitable for filtrating Ductile, Grey Iron, Vermicular Cast Iron and some Iron Alloy and also for filtrating non-ferrous alloy, such as Cooper alloy and Aluminum alloy. It can remove impurities efficiently, and make metal filling steady in mould. It can also reduce air flow and casting impact in mould, and decrease pin hole, sand hole defeats to increase casting quality and product rate.
These series of products are newest products, which are produced through special material formula and latest advanced technology. Compared with normal ceramic foam filters, these new series products can be used at a higher temperature, which have higher strength at room temperature and high temperature. The physical property of this special material enables our filters to have a better thermal shock resistance. They are suitable for harsh casting condition, such as placing on the bottom of vertical runner and casting at high temperature.
Ceramic foam filter is developed as a new type molten metal filter to decrease casting flaw in recent years, designed for filtering impurities from liquid metals. With the distributing pores net structure, they are able to increase the surface areas, 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.
Jintai ceramic foam filter:
Material including al2o3, sic, zro2.
Shape in square, round, cylinder.
Pore size: 8~60ppi
Special size is available upon request.
