ZrO2 Foam Ceramic Filter
Zirconia foam ceramic filters enable molten steel to fill the mold cavity more evenly. During casting, the molten metal exhibits a high tendency for turbulence; however, through the three-dimensional pore structure of the zirconia foam ceramic filter, this turbulence is ultimately transformed into a stable laminar flow. This laminar flow provides better cavity filling, thus reducing impact corrosion of the casting cavity by the molten metal and significantly lowering the scrap rate.
Product Features: Suitable for the production of various grades of cast steel parts, with an application temperature up to 1750℃.
High resistance to thermal shock and gravitational impact; does not crack during casting.
Highly efficient filtration of small non-metallic impurities, purifying the molten metal and improving the surface and internal quality of castings.
Stable quality, high porosity, and excellent filtration effect.
