Ceramic foam filter is a kind of effective molten metal filter. It's three-dimensional connected mesh structure and high porosity has many advantages, for example, large surface area of slags collection, large inner surface area of filtering, small flow resistance, good filtering effect, etc. Ceramic foam filter: Even aperture, high porosity, proper sinter, high strength of anti-flexing and anti-compression. The product, adopted good portiforium foam and high purity ceramic, effectively removes non-metal solid mixture from aluminium and aluminium alloy fusant. It is widely applied to the aluminium fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting.
Ceramic foam filters are different from aperture specifications from 10 to 45ppi, with different sizes and shapes. Besides the general specification, we can offer the product according to the customers requirements.
Functions of ceramic foam filter:
Decontaminate the melting metal liquid
Simplified gating system
Improve the metallurgical structure of the castings
Reduce imparities of the castings
Improve casting quality rate
Reduce casting internal re-oxidation defects
Reduce the surface defects after machining of the castings
