Arffil ceramic foam filters are characterized as high permeation rate, good strength and thermal shock resistance, stable quality and without loosing impurity in high temperature either in big size or small ppi products.
Advantages compared with traditional filtering materials:
Thermal and chemical stability in high temperatureücavoiding the chemical reaction with the filtered molten metal.
High porosity and good mechanical strength in elevate temperature due to its pure ceramic composite.
Full open cell without loosing ceramic particles or powders (snowing) during filtrating.
Low head loss, easy operation, energy save.
Make metal flow reposeful and avoid the sputtering and backset, this increases the surface quality of the cast, prevent the pore disfigurement and finally lower down the waster rate.
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.

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.
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.
Alumina ceramic foam filters mainly used for filtration of aluminum and alloys in filter case .With the excellent corrosion resistance to molten aluminum and strict control of pore size& porosity, the filter can effectively remove micron impurity and provide stable laminar flow to realize higher-quality casting. The alumina ceramic foam filter manufactured by our company has been widely used in purifying system in the founding, low-pressure, semi-continuous, continuous casting of the liquid aluminum and aluminum alloy.
Characteristics:
1, stable chemical composition; 2, excellent bend and compression resistance strength;
3, completely sintering and uniform pore size; 4, three dimensional network structure and small steady-state error;
5, high porosity and low filtration hindrance; 6, high impurities attraction power and perfect filtration effect;
Ceramic foam filter used for casting
Our products have many advantages such as superior porosity, big m2/m3, high temperature resistance and excellent thermal shock resistance (see detail in technical data), it used in foundry, noise elimination and other industries widely. And especially for the foundry & casting industry.
Mechanic deterring: remove big oxide
Filtration: filtrate small impurities and oxide
Commutated function: calm down turbulent f¦claminar flow
Mixed round function: mix the distributaries and confluence flow equality, reduce air bubble
Absorbing function: the myriad eyelets which only been found in microscope can absorb smaller impurities, make more excellent metal liquid

Cff-s is a range of new generation silicon carbide based ceramic foam filters with a consistent, high level performance in terms of metal flow rate and filtration efficiency. Cff-s filters are intended for filtering grey, ductile iron and nonferrous metals at the temperatures up to 1450 â°c. The filters can be placed in the gating system of the mould as well as in combination with exothermic extensions for direct casting/pouring on the filter. They can also be used for continuous non ferrous metal filtering, e.G. Production of copper wires, roads.
Features:
1. High strength
2. Excellent corrosion resistance
3. Outstanding thermal shock resistance
4. Available in kinds of shapes, in a variety of pore sizes, e.G.10ppi, 20ppi, etc.
Functions:
1. Clean iron castings
2. Fewer inclusions
3. Increased casting yield
4. Cost-savings from reduction in scrap
5. Lower costs for machining of the castings
