Ceramic Foam Filter Technology For Aluminum Foundries

Whether your foundry produces standard aluminum castings or critical complex thin wall aerospace.

Ceramic foam filter technology for aluminum foundries.

Typical industrial use of a ceramic foam filter in a filter box which is installed in the metal transfer line from the melting furnace to the dispensing furnace or casting unit shown in the figures 4 and 5. They are manufactured in a range of compositions and sizes to suit the varied processes and equipment used in the aluminum foundry. Drache ceramic foam filters and refractory components. 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.

Ceramic foam filters of selee structure are preferred by aluminum foundries of all types and levels of production due to their superior dimensional control. Innovative products for the foundry industry. Although only implemented by aluminum foundries since the late 1970s ceramic foam filters are increasingly being used to prevent nonmetallic materials from entering the mold cavity resulting in premium quality castings demanded by today s market. Sedex sic ceramic foam filters.

Sedex is a range of silicon carbide based ceramic foam filters designed for use in grey and ductile iron applications to provide a smooth laminar flow of molten metal and prevent the ingress of slag magnesium reaction products inoculant residues or sand grains into the mould cavity the maximum application temperature for sedex filters is 1500 c. Installing ceramic foam filters to running systems can shield your aluminum castings from unwanted nonmetallic materials. The advantages of this design include more than three times the filter area compared to a conventional plate shaped filter of the same size a self supporting geometry a. Coorstek flow rite ceramic filters are used to remove impurities from molten metal in the casting process at foundries worldwide.

As a valuable raw material metals are becoming increasingly important for the environment in terms of quality and cost. Ceramic foam filters cff of selee structure are preferred by aluminum foundries of all types and levels of production due to their superior dimensional control. In excellent shape all over the world. Picture 3 gas heated foam ceramic filter 3 ceramic foam filters in the foundry industry.

Filters can be used with all types of cast irons aluminum and copper based alloys and are available in a broad range of sizes shapes and performance levels. The udicell tubular foam ceramic filters are perfectly suitable for secure filtering of large quantities of liquid metal and feature a distinctive value added design. Alumina ceramic foam filter is mainly for the filtration of molten aluminium and alloys in foundries and. Foundry molten metal filters ceramic foam filters fiberglass fabrics mesh filters.
