Product Description
Alumina Ceramic Foam Filter for Aluminum Casting
Alumina ceramic foam filter is a new type of low-density, high porosity with a three-dimensional network skeleton structure of the filter. And widely used in the aluminum process industry for molten aluminum filtering, so as to improve aluminum quality.
Alumina ceramic foam filter can effectively remove the non-metal solid mixture from aluminum and aluminum alloy fusion, reduce trapped gas, and provide laminar flow and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, to improve the quality of aluminum alloy and other non-ferrous alloy casting, all of which contribute to reducing casting cost, its maximum service temperature of 1200°C.
Alumina ceramic foam filter has the advantages of high porosity, high mechanical strength, stable chemical property, strong corrosion resistance, high adsorption rate, excellent filtering functions, and thermal shock resistance.
It is mainly used for the purification process of aluminum, aluminum alloy, and other nonferrous alloy production, and can also be used as a gas-solid, liquid-solid separation medium, catalyst carrier, burner, and sound-absorbing and environmental protection fields.
The alumina ceramic foam filter is equipped with a gasket on the edges; the gasket assures the proper and tight position of the filter within the filter box. There are different types of gaskets available, e.g. ceramic fiber gaskets, etc., which also can provide alumina ceramic foam filters without gaskets. These types of filters have been favored by customers from Europe and the United States for years.
Alumina CFF Features
1. Superior dimensional tolerances.
2. Stable chemical property.
3. Excellent filtration efficiency.
4. Excellent mechanical strength.
5. Resistant to corrosion and thermal shock resistance.
6. Beveled edges and compressible gasket.
Product Application
Alumina ceramic foam filter is mainly applied to the aluminum and aluminum alloy 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.
