HC Extruded Ceramic Filter for Iron Foundries
FILTEC HC Extruded Ceramic Filter is a cordierite-mullite-based product, it is made
by unique technology. The filter is characterized by precise dimension and high
mechanical strength and excellent resistance to thermal attack and corrosion from
molten iron liquid.

When HC ceramic filter applied, it can remove slag and non-metallic inclusions from
iron liquid, it also reduces the risk of inclusions in casting ,thereby improving the
surface finish and machinability of the finished castings.

FILTEC HC Extruded ceramic Filters are widely used for molten iron together with or
without ceramic foam filter, It is also applied in casting steel foundries.
