Operating Principles
Ceramic foam filter with a high temperature, corrosion resistance, resistance to molten metal erosion, high strength, high pass rate, and the characteristics of the large surface area is mainly used in the field of metallurgy and casting metal liquid
filtration and purification. The flow of a mixture of molten metal passes through foam ceramic porous structure becomes uniform smooth clean molten metal filled the mold to remove the molten steel in the fineness of micron inclusions and some parcels gas reduce the erosion of the sand mold, and reduce product obsolescence rate. Ceramic foam filters can be made of different pore size and porosity, in order to obtain satisfactory filtration effect.
Ceramic Foam Material Ceramic foam filter, depending on the materials: alumina foam ceramic filters, silicon carbide ceramic foam filter, zirconia ceramic foam filter, and magnesium oxide foam ceramic filter.
1. Silicon Carbide Ceramic Foam Filter:
Working Temperature is 1560 Degree Centigrade. In the bronze casting process, the use of silicon carbide ceramic foam filter material is of SiC.
2. Zirconia Ceramic Foam Filter:
Working Temperature is 1700 Degree Centigrade. Steel castings uses zirconia ceramic foam filters. Zirconia ceramic foam filtersmaterial of ZrO2 zirconia. Zirconia heat-resistant temperature of the filter is higher than about 1760 ° C, with very high strength and excellent high-temperature impact.
3. Alumina Ceramic Foam Filter:
Working Temperature is 1200 Degree Centigrade. Alumina ceramic foam filter products effectively remove solid-state mixed with the molten metal, so aluminum alloy can be successfully forged, aluminum foil manufacturing, extrusion processing technology, perfect aluminum products. 10ppi coarse porosity 70ppi of fine porosity range of options.
Ceramic Foam Filter Size:
The size are available in square, round and custom geometric shapes; sizes ranging from 10mm up to 500mm, and thicknesses from 10-50mm. The most common porosities are 10ppi, 20ppi, 30ppi. Higher porosities are available upon request. Custom-made cut-to-size filters are also possible.
