Zirconia cermic foam filter is applied to purge solution of carbon steel, steel alloy and stainless steel, it can endure require of technology of steel and get rid of foreign matter and materials of corroded model. Zirconia ceramic foam filter can also drop turulent and reduce twice oxided foreign matter. Zirconia ceramic foam filter is designed for the filtration of molten steel, alloy steel, and especially for high quality steel alloys casting temperature up to 1700 ° C, which have high porosity (76%-82%), high thremal shock resistance and large specific surface.
