Alumina foam ceramic filter is applicable to the temperature of 1000C and is suitable for the filtration and purification of aluminum and alloy solutions. In order to meet the increasingly high quality requirements of aluminum castings, the use of alumina foam ceramic filter (plate) is increasingly important. In ordinary sand casting clean such as tide mold casting suitable and fixed mold casting suitable such as automotive aluminum parts casting also widely used filter.
Foam ceramic filter sheet advantages:
1. Purification of molten metal
2. Simplification of pouring system
3. Improve the metallurgical organization of castings
4. Reduce inclusions in castings
5. Casting qualification rate
6. Reduction of internal re-oxidation defects in castings
7. Reduction of surface defects after machining of castings
Classification of foam ceramics
Foam ceramics according to its material can be divided into silicon carbide foam ceramics, alumina foam ceramics, oxidation error foam ceramics, magnesium oxide foam ceramics and so on.
