Details:
 Zirconia ceramic foam filter

Application:For the filtration of molten steel and alloy,large scale iron casting
 
Product standard:China national GB/T 25139-2010
 
Zirconia ceramic foam filters are determined for filtering of steel and steel alloys up to the temperature of 1700 °C.
Filters are recommended especially for high quality grades of alloys.
 
-Drop turbulent of molten steel and alloy
-Improve accepted rate of steel casting
-Reduce foreign matter of steel casting
-Drop twice oxide flaw 
-Reduce second-face flaw after machine process
