Zirconia foam ceramic filter is used in the production of steel and large iron castings, which can effec-tively trap non- Metallic inclusions in the metal stream, resulting improvements are lower scrap, increased yield, mechanical properties, good finish and machinability. It is suitable for all steel casting including carbon stee, stainless steel, cobalt, Nickel alloy castings etc. Its diameter from the nanometer to the micron range, porosity is from 20% to 95%, and the use of a temperature can reach up to 1600° C.
With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance, SIC Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc. With their excellent resistance to attack and corrosion from molten iron liquid, zirconia ceramic foam filter can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow, and then the filtered metal is significantly cleaner.
Applications:
High porosity, heat and shock resistance, high intensity, high specific surface area and good stability, seiving, capturing slag and nidation. Besides filtering molten metal with high temperature, zirconia ceramic foam filter can be used as dealing with high temperature gas, catalyst substrate, solid heat exchanger, special packing and so on.
Merits:
Easily installed
*Resistant to molten aluminum
*Non-wetting
*Excellent hot strength
*Dimensionally stable
*Suitable for both horizontal and vertical placement
