Ceramic Foam Filter
Zirconia molten metal foam filter uses high-purity zirconia as the basic raw material, which can withstand high temperatures above 1700°C.
It has very high strength and excellent resistance to high thermal shock, and stable in texture, not easy to be damaged and slag.
The best choice for filtering of determined for all types of steel such as non-alloy, low alloy, stainless steel and high alloy. Filters are recommended especially for high quality grades of alloys.
Parameter
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℃.
