| CERAMIC FOAM FILTER Compared with traditional filtering materials, The CERAMIC FOAM FILTER have obvious advantages: 1. High Thermal Stability, High Chemical Stability,Avoid the chemical reaction with the filtered molten metal. 2. High Mechanical Strength, Large Specific Surface,Efficient in purifying the metal flow. 3. Lower the filtering head loss,easy-operating,save energy. Smooth the metal flow,avoid the spray, spatter and backset,improve the exterior quality of the cast,prevent the pore disfigurement,reduce the inferior rate. 4. Various size, shape and aperture,suitable for kinds of foundry technique. The quality control of The CERAMIC FOAM FILTER is higher than the National Industrial Standard JC/T895-2001 《CERAMIC FOAM FILTER》,our products gained good reputation from customers domestic and oversea. The CERAMIC FOAM FILTER are including CF200 Series(Al2O3), CF400 Series(SiC), CF500 & CF600 Series(ZrO2),Size:10-600mm,Thickness:10-50mm,PPI: 8-60ppi. The CERAMIC FOAM FILTER are widely used in non-ferrous metal smelt, Foundry Industrial of Copper, Aluminium Alloy, Cast Iron, Cast Steel and high temperature fume separator, catalyzer carrier, special filling. New application for sound insulation and aquatic animal products have been exploited.
