Rusal aluminum foundry filter mainly adopts ceramic foam material as filter medium. The ceramic foam filter has a unique three-dimensional connected curved pore network skeleton structure, and the open porosity is 80%-90%. Rusal aluminum casting filter has four filtration and purification mechanisms, namely: screening-filter cake-deep bed filtration mechanism, floating separation mechanism, deep filtration (physical adsorption), […]

The initial foam ceramic filters manufacturing is formed by coating the reticulated polyurethane precursor with a ceramic slurry. The reticulated open-cell foam, preferably polyurethane foam, is impregnated with the ceramic slurry, wherein the entire structure of the reticulated open-cell foam is preferably covered by the slurry. The pore size of the foam is preferably between […]
The purification of metal liquid plays an important role in improving the mechanical properties of castings. At present, the filtering device used to purify the metal liquid is mainly ceramic foam filters for aluminium casting, which can effectively intercept harmful impurities in the metal liquid and convert the metal liquid from turbulent flow to laminar […]
The inclusions are removed in the final processing step before solidifying the molten aluminum into an ingot or billet by filtration. The industry has been completed in the industry for many years by using a variety of technologies, including bed filtration and ceramic foam filter molten aluminum filtration. The production of aluminum ingots and billets […]
