Foundry Foam Ceramic Filter -sales@aluminiumceramicfiber.com

Foundry foam ceramic filter is used to filter aluminum and non-ferrous metal alloys in foundries, especially in the primary and secondary processing of molten metals, as well as the filtration of castings in foundries.

Alumina ceramic foam filter is mainly used in the purification process of aluminum and aluminum alloy production. It can effectively remove various inclusions in the aluminum water with a fineness of micrometers, so that the aluminum water becomes a smooth laminar flow, which is conducive to filling, has excellent aluminum water erosion resistance, and strictly controls the hole size and through-hole rate. A stable filtering effect can be obtained, thereby improving the casting quality, reducing the casting rejection rate, extending the service life, and reducing the casting cost.

Foundry Foam Ceramic Filter

Advantages of Ceramic Foam Filters
1. Filter impurities, such as slag, sand, oxide film, ceramic inclusions
2. Smooth filling can convert turbulent flow into laminar flow and minimize the re-oxidation of metal
3. There is more space on the model board and less metal circulation
4. Reduce the risk of mold erosion in the gate system
5. Reduce the influence of human factors (casting experience, unskilled labor, process safety)
6. Improve the physical properties and surface quality of castings

Foundry Foam Ceramic Filter product has excellent thermal shock resistance, high strength, high porosity and specific surface area. It can increase the specific surface area between the molten metal and the ceramic filter, thereby improving its adsorption capacity and the ability to capture tiny impurities, thereby taking away non-metallic impurities and gases, making the metal stable and purifying the metal liquid.

Features: high mechanical strength, good heat resistance, can remove metal impurities in molten metal, refractory waste, solid refractory alloy, sintered ore when casting products, reduce vent holes in castings, improve casting quality, reduce casting costs, and increase productivity.

Large-size alumina foam ceramic filter plates are widely used in aluminum casting workshops such as aluminum alloy casting rods, slabs, aluminum foil, aluminum plastics and high-end aluminum profiles.

The filtration rate of 15-20 micron impurity particles is 98.3%, which can help to obtain perfect aluminum products. Various specifications can be produced according to customer requirements, the mesh size can be selected from 25ppi to 60pp, and the maximum size can be up to 26 inches.
