Filtro de espuma cerámica CFF

CFF Ceramic Foam Filter mainly for 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 bottom-line profit.

CFF Ceramic Foam Filter Features

-Reducir los desechos relacionados con las inclusiones.
-Reducir los costes relacionados con los defectos de inclusión.
-Aumentar la productividad con mayores velocidades de extrusión o laminación.
-Aumenta la flexibilidad de fundición gracias a la facilidad para cambiar de aleación.
-No se admiten objetos metálicos.

CFF Ceramic Foam Filter 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.

CFF Ceramic Foam Filter 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.
