The foundry alumina ceramic foam filters are a special technology. The ceramic foam filter has a foam-like porous structure of ceramic products, and its lightweight, chemical stability, large area through-hole rate, corrosion resistance, high strength, good thermal shock resistance characteristics.
The Foundry Alumina Ceramic Foam Filters has the advantage of high temperature, corrosion resistance, resistance to erosion of molten metal, high strength, high throughput rate. The foam ceramic filter is mainly used for the filtration of liquid metal in metallurgy and metalworking field.
The flow of a mixture of molten metal passes the porous structure of the Adtech ceramic foam filter becomes uniform, smooth and clean. The removal of fineness micrometric inclusions in molten metalcan reduce sand mold erosion and reduce product obsolescence rate.
The foundry alumina ceramic filters can be made with different pore sizes and porosity, so as to achieve a satisfactory filtration effect.
Role of Foundry Alumina Ceramic Foam Filters
- Filter slag to reduce the harm of slag to castings.
- Filter out the bubbles in the molten metal.
- Rectify, make the flow of molten metal change from turbulent flow to laminar flow, reduce the secondary oxidation and gas absorption of molten metal, and improve the performance of castings.
Foundry Ceramic Foam Filter Material
Ceramic foam filter, depending on the material: alumina foam ceramic filters, silicon carbide ceramic foam filter, zirconia ceramic foam filter and magnesium oxide foam ceramic filter.
In the bronze casting process, the use of silicon carbide ceramic foam filter material is SiC.
Steel castings use ceramic zirconia foam filters. ZrO2 Zirconia Ceramic Foam Filters Material. The heat resistance temperature of the filter zirconia is over about 1760 ° C, with very high strength and excellent high temperature impact.
Foundry alumina ceramic foam filter products effectively remove the solid state mixed with molten metal, so that the aluminum alloy can be successfully forged, aluminum foil making, processing technology by extrusion, perfect aluminum products. 10ppi coarse porosity 70ppi fine porosity range of options.
