The main working principle of ceramic foam filter is to make the fluffy and billowing liquid metal become stable, uniform and clean liquid metal after passing through foam ceramic honeycomb holes. The unique honeycomb structure can adsorb some small particle impurities in steel (iron) water, such as non-metallic particles, slag, refractory material fragments, etc. into the filter. Secondly, the smooth metal laminar flow fills the model better, on the one hand, it overflows gas, on the other hand, it reduces erosion on the model, and reduces the product scrap rate. Therefore, it is possible to improve the metallographic structure and mechanical properties of castings, produce high-quality precision castings, reduce the scrap rate of castings, reduce tool wear during casting processing, and significantly increase economic and social benefits.
Ceramic foam filter is just developed as a new type of molten metal filters to decrease casting flaw in recent years. It is made from high quality ceramic materials, whose main components are Al2O3, Sic, ZrO2, MgO etc.All the three types filters are available in square, round and custom geometric shapes; sizes ranging from 10mm up to 600mm, and thicknesses from 10-50mm. Pore densities from 10-60 pores per inch are available.
