Alumina Ceramic Foam Filters are specially designed for aluminum liquid filtration. They are made of high-purity alumina and have a porous structure. They can effectively remove impurities, oxides and inclusions in aluminum liquid, significantly improving the quality of aluminum castings.
Main Features of Alumina Ceramic Foam Filters
- High heat resistance: can withstand high temperatures of aluminum liquid (above 700°C).
- Chemical stability: does not react with aluminum liquid and is corrosion-resistant.
- High porosity: porous structure provides efficient filtration.
- Mechanical strength: can withstand the impact of aluminum liquid and is not easy to break.
Application Areas of Alumina Ceramic Foam Filters
- Aluminum alloy casting: used for aluminum casting production in the fields of automobiles, aerospace, etc.
- Aluminum profile extrusion: filter aluminum liquid and improve the surface quality of profiles.
- Aluminum plate and strip production: purify aluminum liquid and improve plate performance.
- Recycled aluminum processing: remove impurities in recycled aluminum and improve recycling quality.
Filtration Principle
- Mechanical interception: intercept large particles of impurities through pores.
- Adsorption: adsorption of fine oxides and inclusions on the surface.
- Turbulence effect: changes the flow of aluminum liquid and promotes the separation of impurities.
Advantages
- Efficient purification: significantly reduces impurities in aluminum liquid.
- Improve casting quality: improve mechanical properties and surface finish.
Precautions for use
- Preheating: preheat to close to the temperature of aluminum liquid before use to prevent thermal shock.
- Installation: ensure that the filter plate fits tightly with the filter box to avoid aluminum liquid bypass.
- Regular replacement: replace in time according to usage to avoid clogging and affecting the filtering effect.
Summary
Alumina ceramic foam filter plate is an ideal choice for aluminum liquid filtration, which can effectively improve the quality of aluminum castings and is widely used in aluminum alloy casting, profile extrusion and other fields. Its high-efficiency filtration, high temperature resistance and long life make it an indispensable material in the aluminum processing industry.
