Product Description

 

Product Description

Ceramic foam filters are a new type of molten metal filter for filtering impurities from liquid metals to decrease casting flaws. They have the characteristics of lightweight, 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 casting are one of the most main reasons for casting defects. Ceramic foam filters have a three-dimension net structure, they are able to increase the surface areas and absorb the sinter, the liquid metal becomes pure, water quality problems such as sand pores and air pores are much less, and the casting 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 temperatures, carrier of catalyzers, solid heat exchange, and advanced filling for the 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 in the castings.
5. Improve casting quality rate.
6. Reduce casting internal re-oxidation defects. 
7. Reduce surface defects after machining the castings.

We are a professional supplier of foundry filters in China, ceramic foam filters are the most effective filtering system available and have a unique three-dimension channel structure. Our filtration systems can help customers remove inclusions, reduce turbulence and provide rapid and consistent flow to improve casting quality and reduce the defective rate and casting cost. They are widely used for aluminum, copper, iron, and steel casting applications.
Our ceramic foam filters have the characteristics of lightweight, 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 impurities of 1-10μm. 
Our ceramic foam filter is not only applied for molten metal filtering in high temperatures, 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 the chemical industry.

We can offer various materials of ceramic foam filters, such as silicon carbide foam ceramic filters, zirconia foam ceramic filters, magnesia foam ceramic filters, and alumina foam ceramic filters, we can produce square, rectangular and round filters of dimensions required by the client and porosity 10 PPI and 40 PPI (pore per inch).
