Ceramic Foam Filter

Ceramic Foam Filter

Ceramic Foam Filter from AdTech Metallurgical Materials Co., Ltd has been focusing on research, development, production and marketing of the adhesive ceramic foam filter(CFF) for aluminum alloy casting Since 2012.

Advantages for Ceramic Foam Filter

Adopt adsorption principle for filter, can effectively remove big piece inclusions in molten aluminum, and effectively adsorb tiny inclusions.
No broken bits drop out, effectively reduce the pollution of molten aluminum.
Superior thermal shock resistance, improve erosion resistance ability of molten metal.
Automatic flow production，3 calibration procedures，precision size，fit the filter bowl tightly.
Improve the surface appearance and performance, purify molten aluminum.

Assembles for Ceramic Foam Filter:

• Ceramic Foam Filter
• Ceramic Fiber Sealing Gasket
• Filter Bowl

Application for Ceramic Foam Filter

AdTech’s ceramic foam filter is produced basing on carrier with solid reticular structure and combined organic foam pores. The producing procedure is as below, put carrier into the thixotropic alumina slurry, adopt square to center correcting automatic extrusion process, so that slurry evenly deposits in foam skeleton of carrier, after drying solidification, then carrier will turn into final product by roasting formed under 1180 ℃ high temperature. Filter is installed in the filter bowl for filtrating impurity in molten aluminum alloy, which helps to meet the requirement of production in high value-added, high-tech performance aluminum alloy precision casting, such as computer hard drive, PS baseboard for printing, canning materials, fan blades for turbojet engine, etc.

Sealing gasket for Ceramic Foam Filter

Ceramic filter is surrounded by Sealing gasket, laying between filter and filter bowl, to prevent molten aluminum leaking through interface. AdTech’s filter adopts sealing gasket in 3 different types, fiber paper material, fiber cotton material, expanding cotton material.
