Home  Products  Ceramic foam filters  Filtration of steel alloys


The ZrO2 based filters are intended for filtering steels, in particular highly alloyed steels, where high reliability and chemical purity is requested (aircraft industry, power sector, etc.). High mechanical strength is their great advantage, because it enables their application for filtration systems of heavy and sturdy castings (carousels, grates).


The Al2O3 – C based filters are intended for filtering ferrous metals (nodular iron, steel) up to the temperatures of 1700 °C. High filter stability during casting, outstanding thermal conductivity and low weight create the preconditions for fast filter heating/priming and minimize pressure losses. By their features they are predetermined for direct casting through the exothermic sleeves and for filtering larger nodular iron castings.
