Product Description

Alumina ceramic foam filter is a kind of effective molten metal filter. It's three-dimensional connected mesh structure and high porosity has many advantages,for example, large surface area of slags collection.large inner surface area of filtering,small flowresistance,good filtering efect,etc.


Alumina ceramic foam filter --size can be customized


Alumina Ceramic Foam Filters mainly for filtration of aluminium and aluminium alloys in foundries and cast houses. With their excellent resistance to attack and corrosion from molten aluminum, they can effectively remove 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, all of which contribute to bottom-line profit.



Alumina Ceramic Foam Filters Common Size: 


Alumina Ceramic Foam Filters is available in all common sizes: 7", 9", 12", 15", 17", 20", and 23". We offers the whole range of porosities from PPI 10 up to PPI 60 (PPI = pores per inch). Custom-made cut-to-size filters are also possible.


 


Alumina Ceramic Foam Filters Gasketing:


Alumina Ceramic Foam Filters is equipped with a gasket on the edges. The gasket assures the proper and tight position of the filter within the filter box. There are different types of gasket available, eg. Ceramic fibre gasket etc. Also you can choose Alumina Ceramic Foam Filters without gasket.

Product Effects


  Advantage:


♦ Applied to improve the quality of aluminum alloy and other non-ferrous alloy casting  
♦ Improve metallurgical structure
♦ Enhance mechanical properties
♦ Change turbulence into laminar flow


♦ The surrounding of the filter is sealed with expanded gasket. When the temperature is above 450°C, 200% expansion of the gasket will happen to prevent floating and leakage of liquid aluminum through interface.


♦ The filter can effectively remove big piece inclusions in molten aluminum, and effectively adsorb tiny inclusions.


 


Functions


1.Decontaminate the melting metal liquid


2.Simplified gating system


3.Improve the metallurgical structure of the castings


4.Reduce imparitied of the castings


5.Improve casting quality rate


6.Reduce casting internal re-oxidation defects


7.Reduce the surface defects after machining of the castings


 


Performance and Applications


1.Filter-PAL filter is an alumina ceramic product with three-dimensional network structure through high-temperature sinterings


2.High strength, erosion resistance, strong adsorption of impurities, can effectively remove tiny inclusions in molten aluminu


3.Widely used in the aluminum foil roll casting blank, production of aluminum and automobile wheel hub casting blank


4.Higher applicability and economic
