ceramic foam filter cast slabs and rolled sheets

  • The 30ppi ceramic foam filter casting is a porous ceramic product with an open porosity of up to 80-90% and a bulk density of only 0.3-0.6g/cm3. It has a unique three-dimensional network framework and interpenetrating pore structure. Filtration and impurity removal of ceramic foam filters can significantly improve ingot quality and reduce scrap rate.


    Inclusions are any solid or liquid foreign matter above the liquidus temperature. Common non-metallic inclusions include oxides, carbides, borides, etc. In addition, some undesired intermetallic compounds can be present in high alloy melts.

    Non-metallic inclusions in lead melts include 1. Oxides: alumina, magnesia, calcium oxide, etc. 2. Coarse Ti-B particles of residual refiner Al-Ti-B master alloy 3. Refractory brick fragments, falling chutes, and protective coatings on tools.


    Inclusions and gases in metals significantly affect the strength, fatigue resistance, corrosion resistance, and stress corrosion cracking properties of the material. Effectively controlling the oxide inclusions in the melt and improving the quality of cast slabs and rolled sheets have become the common goals pursued by various countries' metallurgical, foundry and material industries. Casting with a 30ppi ceramic foam filter can remove most of the inclusions in the aluminum alloy melt.


    Aluminum and its alloys are easy to oxidize and absorb gas during the smelting and pouring process, and defects such as inclusions and pores are easily formed during the die-casting process, which is unfavorable to the alloy structure, thereby reducing the mechanical properties and corrosion resistance of the alloy, and reducing the yield. Therefore, reasonably controlling the smelting process and improving the quality of aluminum melt is the key to improving the quality of aluminum die castings.
