Product Description

Ceramic foam filter

Product Description
Ceramic foam filters are a new type molten metal filter for filtering impurities from liquid metals to decrease casting flaw. They have 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.
Non-metallic inclusions in a casting are one of the most main reasons of casting defects. Ceramic foam filters have three-dimension 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.
Ceramic foam filters are not only widely applied in the plant of metal casting such as the casting of steel, iron, copper and aluminum, but also be applied in gas treatment in high temperature, carrier of catalyzer, solid heat exchange and advanced filling for chemical industry.
We have developed a series of ceramic foam filters which are made of different materials such as alumina, silicon carbide, zirconia and magnesia. All of the materials are available in square, round and custom geometric shapes; Sizes ranging from 10mm up to 600mm; And thicknesses from 10-50mm. Pore densities from 10-60 PPI (pores per inch) are available.

Ceramic Foam Filter Features
1. Decontaminate the melting metal liquid.
2. Simplified gating system.
3. Improve the metallurgical structure of the castings.
4. Reduce impurities of the castings.
5. Improve casting quality rate.
6. Reduce casting internal re-oxidation defects. 
7. Reduce the surface defects after machining of the castings.

We are the professional supplier of foundry filters in the china, ceramic foam filters are the most effective filtering system available, has a unique three-dimension channel structure. Our filtration systems can help customers remove inclusions, reduce turbulence and provide rapid and consistent flow to improving casting quality and reducing defective rate and casting cost. They are widely used for aluminium, copper, iron and steel casting applications.
Our ceramic foam filters have 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. It not only can filter residuum, but also can adsorption especially for tiny impurity of 1-10μm. 
Our ceramic foam filter is not only applied for molten metal filtering in high temperature, But also be applied purification of high temperature gas dust, sound insulation, biological enzyme carrier in medical preparation, catalyst carrier substrate, solid heat exchange and advanced filling for chemical industry.
We can offer various materials of ceramic foam filter, such as silicon carbide foam ceramic filter, zirconia foam ceramic filter, magnesia foam ceramic filter, alumina foam ceramic filter, we can produce square, rectangular and round filters of dimensions required by the client and porosity 10 PPI and 40 PPI (pore per inch).
 Ceramic foam filter size:
