Description

Compared with traditional filtering materials, GMI�  CERAMIC FOAM FILTER have obvious advantages：1)Thermal and chemical stability in high temperature，avoiding the chemical reaction with the filtered molten metal; 2)High porosity and good strength in elevate temperature due to its pure ceramic composite; 3) full open cell without loose ceramic particles or powders( snowing) during filtrating.
There are four types of ceramic foam filters available, CF**0 is alumina based ceramic foam filters, that  can be used up to a limit of ***0 oC. They are most suited for the filtration of molten aluminum and its alloys, and part of molten copper and its alloy; CF**0 is silicon carbide based filter, that can withstand temperatures up to ***0oC and be used in the filtration of casting iron, copper and its alloys, CF**0 is zirconia- toughed- alumina ceramic foam filter that can withstand temperatures up to ***0oC and used in the filtration of carbon steel and its alloys.; and CF**0 is partial stabilized zirconia filter withstanding temperatures up to ***0oC and suitable for filtration of steel, stainless steel and super alloys.
