Ceramic Foam Filter

Ceramic Foam Filter

Refractory Reticulated Structure Zirconia Ceramic Foam Filter

Zirconia Ceramic Foam Filters are used for filtration of all types of steel like unalloyed, low alloyed, stainless and high-alloyed. Filters are recommended especially for high quality grades of alloys.

 

With their excellent resistance to attack and corrosion from molten steel liquid, they can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow, and then the filtered metal is significantly cleaner.

 

Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects. They are the best choice for filtering of determined for filtering of steel and steel alloys up to the temperature of 1700℃.

Zirconia ceramic foam filters are used to melt all types of steel such as non-alloy, low alloy, stainless steel and high alloy. Filters are especially recommended for alloys of high quality grades. They have good resistance to attack and corrosion of liquid steel, can effectively remove inclusions in liquid metal, reduce trapped gas in liquid metal, and provide laminar flow, so that the filtered metal is significantly clean. Cleaner metals lead to higher quality castings, less scrap and fewer inclusion defects. They are the best choice for filtering of determined for filtering of steel and steel alloys up to the temperature of 1700℃.

Refractory Reticulated Structure Zirconia Ceramic Foam Filter

Appearance:

● There should be no through-crack in the length direction (or diameter).

● Pore density deviation: ±3ppi

● Fine non-penetrating cracks are allowed, but the length of the continuous lines should not exceed 10mm.

● The product should not have slag phenomenon.
