The aluminum melt filtration treatment after the hydrogen removal is the most effective and reliable means to remove non-metallic inclusions. There are many kinds of filtering methods, the most effective ones are corundum filter tube and foam ceramic filter plate. The corundum tube filter has high filtration efficiency, but it is expensive and inconvenient to […]
The porous ceramic filter medium has a primary porous structure imparted by the foam macrostructure, which is the exoskeleton of the polyurethane precursor, and is replicated by coating with slurry, followed by drying and firing. The primary pore size is usually 3 holes per linear inch (ppi) to 100 ppi, more preferably 20 ppi to […]
