Model Name:NX-PTW-G

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 Degree 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
