Foam Ceramic Filter Plate, Porous Foam Ceramic Plate:
Ceramic foam filter is just developed as a new type of molten metal filters to decrease casting flaw in recent years. It is made from high quality ceramic materials, whose main components are Al2O3, Sic, ZrO2, MgO etc. Ceramic Foam Filter has the characters of light weight, high mechanical strength, large specific surface areas, high porosity, excellent thermal shock resistance, chemical corrosion resistance and high temperature stability in molten metal. With the distributing pores net structure, they are able to increase the surface areas, and absorb the sinter, the liquid metal becomes more pure, waster quality problems such as sand pore and air pore are much less and the cast quality becomes much better.
Ceramic Foam Filter are widely used in metallurgy and casting industry for the filter of melted metal. With their excellent thermal shock resistance and corrosion resistance from molten aluminum/sic/zirconia/magnesia, they can
Effectively eliminate inclusions, reduce trapped gas and provide laminar flow, and then the filtered metal is significantly cleaner. Cleaner metal results in higher-quality castings, less scrap, and fewer inclusion defects.
Foam ceramic filter based material--polyurethane foam, which has many porosity, open cell, well breathable, well filtering. Compared with traditional filtering materials, our Ceramic Foam Filters is not only with characteristics of high porosity, low loss of pressrue, large specific surface, high mechanical strength and non- reacting with the melten metal being filtered in high temperature, but also with properties of easy operation, energy-saved and low cost. It can improve the cast quality in large scale.
Advantages:
*Good work strength under high temperature, good thermal shock resistance and melted metal inflow resistance
*High strength under room temperature, mechanic push resistance
*Obvious filter effect
*Ease the uneven inflow of casting, smooth the casting process, avoid surface defect
*Have a large and even melted inflow rate
*Good chemical stability, not affected by of melted meta, no change in its chemical compound
*Precise dimension and can be used in production line automatic filter mounting equipment
Ceramic Foam Filter Classifications:
Silicon Carbide Ceramic Foam Filter: Apply to improve the quality of ductile, grey and malleable iron casting
Alumina Ceramic Foam Filter: Apply to inprove the quality of aluminum alloy and other ono-derrous alloy casting
Zirconia Ceramic foam Filter: Apply to purity the molten carbon steel, steel alloy and stanless steel
Magnesia Ceramic Foam Filter: Apply to magnesium alloy and other actived alloy
