Zirconium oxide ceramic foam filter


Zirconia ceramic foam filters for steel castings and large cast iron pieces, the effective removal of liquid metal inclusions in the bulk, absorption small impurities and harmful elements in reducing gas to improve the mechanical properties of castings.

Apply to all steel, including carbon steel, stainless steel and cobalt base super alloy and so on.

    Diameter / length 75120mmthickness2225mm

    Diameter / length125150mmthickness2535mm

    Aperture1020PPICan be customized

Filtering capabilities

Filtration volume per unit area of the filter is recommended:

    Carbon Steel    1.0-2.7 kg/cm2

    Stainless Steel   1.0-4.0 kg/cm2


    1Try to avoid direct impact of molten metal filters, filter direct impact of pouring height should not exceed 300mm 300mm.

2Filter before the gas blow off the residue with crumbs.

3The best use of open-pouring system, to avoid the gas volume

Round table type of zirconia steel filter


Round table zirconium oxide filters for steel precision casting, place the gate in the cone cup. This type of filter and pouring cup form a well supported, to avoid casting process molten steel flow from the filter side to improve the filtering effect.
