Ceramic Foam Filter Serials
1.SIC,Alumina,Zirconia,Magnesia etc.materials
2.Good hardness,quality assurance
3.ISO 9001 PLANT
Compared with traditional filtering materials,the ceramic foam filter has obvious advantages:1. Thermal and chemical stability in high temperature,avoiding the chemical reaction with the filtered molten metal;2. High porosity and good mechanical strength in high temperature due to its pure ceramic composite;3. Low head loss,easy operation,energy-saving;4. Making metal liquid flowing at stable speed and avoiding the sputtering and backset,thus increasing the surface quality of the cast part,preventing the pore disfigurement and finally lower down the unqualified rate;5. Various sizes,shapes,apertures are available for kinds of foundry technique. Main Performance Index:
