Ceramic Filters

Filter installed in the gate system to retain exogenous and/or endogenous inclusions such as slag, foam or oxodic impurities from the melt flow
significant feature is the homogeneous pore size with cellular ceramics filters (extruded filters). Due to the production, an identical ceramic foamfilter pore size is impossible. Pore density is indicated as pore quantity per cm of filter length or ‑ commonly ‑ in ppi (pores per inch).
Asting filters may also enable a metal flow homogenization and deceleration, i.e. turbulent flows are turned into laminar flows. This results in significantly less re-oxidation within the mold and in a minimzation of the sanderosion risk Depending on the purpose, zirconium silicate, zirconium oxide, silicon carbide and mullite are used as filter materials
