Ceramic foam filters have 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. With more than ten years of scientific research and development, DXY has developed a series of ceramic foam filters which are made of different materials such as Aumina, Silicon Carbide and Zirconia.
Ceramic Foam Filter Classifications:
*Alumina Ceramic Foam Filters
Alumina Ceramic Foam Filters mainly for filtration of aluminium and aluminium alloys in foundries and cast houses. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects, all of which contribute to bottom-line profit.
*Zirconia Ceramic Foam Filters
Zirconia Ceramic Foam Filters are used for molten all types of steel like unalloyed, low alloyed, stainless and high-alloyed as well as Nickel and Cobalt-based super-alloys.
*Silicon Carbide Ceramic Foam Filters
Silicon Carbide Ceramic Foam Filters mainly for filtration of cast iron and non-ferrous alloys.
Advantages
*Easily installed
*Resistant to molten aluminium
*Non-wetting
*Excellent hot strength
*Dimensionally stable
*Suitable for both horizontal and vertical placement
Applications
*Sand casting
*Investment casting
*Shell casting
*Low-pressure die casting
*Permanent mould casting
*Holding and transfer systems
