Alumina
foam ceramic filter adopts advanced environmental protection production
technology, high opening rate, uniform pore structure and high surface
strength. Mainly used in aluminum and aluminum alloy and molten metal below
1000 ℃ filtration, can effectively filter metal oxide slag, scale,
non-metallic inclusions and gate groove lining and other residues, to solve the
aluminum and aluminum alloy on the internal defects sensitive issues.
