Alumina Ceramic Foam Filter for Aluminum Filtration is a high-efficiency filtration material designed for aluminum and aluminum alloy melt filtration. It is mainly used to remove impurities and gases in the melt and improve the quality of castings. The following is its key information:
Features of Alumina Ceramic Foam Filter for Aluminum Filtration
- High porosity: usually 80%-90%, ensuring good filtration effect and melt fluidity.
- High temperature resistance: can withstand the high temperature of aluminum melt (700°C-800°C).
- Chemical stability: does not react with aluminum melt to avoid secondary pollution.
- High mechanical strength: can withstand melt impact and mechanical stress.
- Uniform pore size: effectively intercept impurities of different sizes.
Application of Alumina Ceramic Foam Filter
- Aluminum casting: used for melt filtration of aluminum and aluminum alloy castings to improve surface quality and mechanical properties.
- Aluminum processing: filter aluminum melt before rolling, extrusion and other processes to reduce defects.
- Recycled aluminum: filter and recycle impurities in aluminum to improve the quality of recycled aluminum.
Advantages
- Improve casting quality: effectively remove impurities, reduce pores and inclusions.
- Improve production efficiency: high porosity reduces melt flow resistance.
- Reduce costs: reduce scrap rate and save production costs.
- Environmental protection: reusable and reduce waste.
Selection points
- Aperture: select the appropriate aperture according to the size of impurities.
- Size: select the appropriate size according to the casting equipment.
- Porosity: high porosity helps to improve filtration efficiency and melt fluidity.
- Heat resistance: ensure that it can withstand the high temperature of aluminum melt.
Use and maintenance
- Preheating: preheat to close to the melt temperature before use to prevent thermal shock.
- Installation: ensure that the filter is firmly installed to avoid melt leakage.
- Replacement: replace in time after reaching the service life to maintain the filtration effect.
Summary
Alumina ceramic foam filter performs well in aluminum filtration and can effectively improve casting quality and production efficiency. Correct selection and use can significantly improve the performance of aluminum and aluminum alloy products.
