Tag Archives: Ceramic Filters for Aluminum Casting

The foam ceramic filter plate is widely used in aluminum foundries because of its convenient use, good filtering effect and low price. In developed countries, more than 50% of aluminum alloy melts are filtered by foam ceramic filter plates. The ceramic foam filter plate is generally a filter with a thickness of 50 mm and […]

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 high temperature ceramic filter has a three-dimensional network skeleton structure, which is prepared by applying the ceramic slurry to a synthetic resin foam, it has an open-cell three-dimensional network skeleton structure, followed by drying and firing. The ceramic slurry contains 20-40 parts by weight of aluminum titanate, 40-60 parts by weight of mullite, 2-20 […]
