Zirconia Ceramic Foam Filter:
Zirconia ceramic foam filter has the advantages of high prorosity, low loss of thermal shock, high mechanical strength at normal and high temperature, large specific surface, good chemical stability and excellent filtering functions of screen, filtering residum collection and absorption especially for tiny impurity of 1~10um. The three-dimension structure can improve the cast quality in large scale by changing the molten metal from turbulence flow to lamellar flow, removing the gas and smoothing the casting. It is not only applied for molten metal filtering in high temperature, but gas treatment in high temperature, carrier of catalyzer, solid heat exchange and advanced filling for chemical industry.
Advantages:
*Reduce casting inclusions
*Improve casting microstructure
*Reduce internal re-oxidation of the casting defects
*Improve casting quality rate
*Reduce surface defects after casting and machining machining tool wear
*Simplify the gating system
