Compared with traditional filtering materials, our Ceramic Foam Filter are not only with characteristics of high porosity, low loss of pressure, large specific surface, high mechanical strength and non-reacting with the molten metal being filtered in high temperature, but also with properties of easy operation, energy-saved and low cost. It can improve the cast quality in large scale.

Apply to purge solution of carbon steel, steel alloy and stainless steel, it can endurere quire of technology of steel and get rid of foreign matter and materials of corroded model. It can also drop turulent and reduce twice oxided foreign matter.
