Alumina Ceramic Foam Filter Plate
Alumina Ceramic Foam Filter Plate is mainly for the filtration of aluminum and alloys in foundries and cast houses.
With the excellent resistance to attack and corrosion from molten aluminum, the filter 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 the bottom-line profit.

Alumina Ceramic Foam Filter Plate Pre Heating
Alumina ceramic foam filters are normally applied by placing them into a filter box. It is important to pre-heat both filter and filter box before use. During pre-heat care must be taken to control both heat up rate and temperature distribution. This minimizes thermal shock and stresses in the filters and filter box refractory.
Alumina Ceramic Foam Filter Plate Priming
Before a filter can be used, it must be completely wetted by liquid metal. This happens during the start-up of the casting operation. The amount of metallostatic pressure (or priming head) required to wet filters depends on alloy, metal temperature, pre-heat uniformity, pre-heat temperature, incoming metal quality,pre-filter treatments and on the cell size of the filter.
Alumina Ceramic Foam Filter Plate effectively removes large inclusions in aluminium liquid, adsorption of micro-inclusions in particle, to improve surface quality, improving product performance, microstructure, improving yield, widely used in aluminium alloy casting and other production areas.
