Ceramic foam filter is a porous ceramic material used to filter metal melts. It is mainly used to remove impurities and inclusions in the melt and improve the quality of the metal. The following is a brief introduction to it:
Materials and Structure of Ceramic Foam Filters
Material: Usually made of ceramics such as alumina, silicon carbide, and zirconium oxide.
Structure: It has three-dimensional mesh pores with a porosity of up to 80-90%, and the pore size can be adjusted according to demand.
Working Principle of Ceramic Foam Filter
When molten metal passes through the filter, impurities are trapped by the pores, and clean metal passes through.
Main Applications
Foundry Industry: Used for filtering metals such as aluminum, copper, and iron.
Aerospace: Improve the quality of high-temperature alloy castings.
Automotive Industry: Used for casting engine parts.
Advantages of Ceramic Foam Filters
- High-efficiency filtration: Significantly reduce impurities.
- High temperature resistance: Suitable for high-temperature melts.
- Chemical stability: Does not react with the melt.
- Mechanical strength: Can withstand the impact of metal flow.
Manufacturing process of Ceramic Foam Filters
Foaming method: a porous structure is formed by a foaming agent, and then sintered at high temperature.
Organic foam impregnation method: the ceramic slurry is impregnated into the organic foam, and porous ceramics are formed after sintering.
Selection and use
Aperture selection: select the appropriate aperture according to the size of the impurities and the type of metal.
Installation and maintenance: correct installation and regular replacement to ensure the filtering effect.
Market and development
With the improvement of quality requirements in the foundry industry, the demand for ceramic foam filters continues to grow, and they may be used in more fields in the future.
In summary, ceramic foam filters effectively improve the purity of metal melts through their porous structure and are widely used in many industrial fields.
