Zirconia ceramic foam filter is mainly used below 1700º C molten metal filtration. Suitable for all steel casting including carbon steel, stainless steel, cobalt, Nickel alloy castings etc. It can effectively remove inclusions in molten metal, adsorbed impurity, reduce the molten metal in the gas and the harmful element content, resulting decrease the reject rate, increased yield, produce high quality castings.
Using scope of zirconia ceramic foam filter:
Zirconia Ceramic Foam Filter is mainly used in the filtration of carbon steel; Alloy steel, stainless steel, high temperature alloy castings, Because of the unique high-temperature components, but also suitable for high-precision aerospace castings.
Specification of zirconia ceramic foam filter:
We can produce round, square and other geometric shapes of zirconia ceramic foam filter.
