Alumina Ceramic Foam Filter are just developed as a new type molten metal filter to decrease casting flaw in recent years. With its characteristics of light-weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, erode resistance, high-performance. Alulmina Ceramic Foam filter is designed for filtering impurities from molten Iron & Alloy, nodular cast iron castings, grey iron castings and malleable castings, Bronze casting, etc.
With their excellent resistance to attack and corrosion from molten iron liquid, it can effectively remove inclusions, reduce trapped gas from liquid metal and provide laminar flow, and then the filtered metal is significantly cleaner.
It is widely applied to the aluminium fusant filter equipment of continuous casting, half-continuous casting, gravity casting, and low pressure casting. The size are available in square, round and custom geometric shapes, sizes ranging from 10mm up to 600mm, and thicknesses from 10-50mm. The most common porosities are 10ppi, 15ppi, 20ppi, 25ppi.
Applications:
*Effectively remove and absorb impurities
*Improve the surface quality, product performance and microstructure effectiveness
*Mainly used in the construction, electricity, condensing tubes, cable and other aluminum alloy precision casting
Advantages:
Even aperture, high porosity, proper sinter, high strength of anti-flexing and anti-compression, effective filtering, etc.
