Product Description
High Performance SIC Al2O3 ZrO2 Ceramic Foam Filters for molten metal filtration
Model Name: NINGXIN-CFF-Z1
Application: For the filtration of molten Iron,copper, aluminum and steel alloy
Ceramic foam filters offer a simple, reliable and costeffective method to remove inclusions. Filtering with CFF is a supplement to metal treatment within the furnace, such as fluxing and degassing or inline filtration.
Ceramic foam filters have an open pore reticulated structure with very high porosity and surface area to trap inclusions. The open foam structures are compose of ceramic material, such as alumina, mullite or silica. Alumina is the most common filter material. Ceramic foam filters operate in a deep bed filtration mode where inclusions smaller than the pore openings are retained throughout the cross-section of the filter.
CFFs typically are a polyurethane foam coated with a ceramic slurry then dried and fired. During firing, the polyurethane foam dissipates leaving behind a porous ceramic structure. The ceramic can be a phosphate-bonded alumina and pore sizes and thicknesses can vary.
