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. Functions of ceramic foam filter
1. Decontaminate the melting metal liquid
2. Simplified gating system
3. Improve the metallurgical structure of the castings
4. Reduce imparities of the castings
5. Improve casting quality rate
6. Reduce casting internal re-oxidation defects
7. Reduce the surface defects after machining of the
castings
