CFF Filtration Box (CFB)
CFF Filtration Box (CFB)
• The most widely used high-efficiency filtration system
Equipment Introduction
- The CFB is widely used for molten aluminum filtration in the aluminum casting process to prevent the particulate impurities in molten aluminum from entering the casting blank and affecting the quality of aluminum products.
- A satisfactory filtration effect can be achieved if a right type of filtration box and correct specifications of the CFF filtration board are selected in accordance with the quality requirements of casting products, the flow rate of molten aluminum, the total filtration amount of molten aluminum and the purity of molten aluminum.

Filtration Box Features
• Significant filtration effects. It meets the production requirements of ordinary products and even the stringent production requirements of aluminum alloy can materials, aero-metals and other relevant materials. The filtration box can effectively filter out bulk inclusions in the molten aluminum, adsorb small inclusions in the molten aluminum, refine the crystalline structure of castings, reduce the content of hydrogen in the molten aluminum and lower the content of harmful elements such as Na and K in the molten aluminum by adsorption.
• The filtering method is easy to use. Standardized and serialized production of the CFF filtration boards has been realized. Different filtration effects can be achieved if filtration boards with different pore sizes (20-60ppi) are combined together in use according to the quality and flow requirements of molten aluminum.
• Economical. The filtration board has high strength and resistance to abrasion by molten aluminum, good thermal shock resistance and a long service life; the heating cover ensures that one filtration board can be reused more than 6 times in the filtrate, thereby reducing the cost of consumables; the lining of the filtration box, similar to that of the degassing box, has high aluminum tolerance, heat preservation and resistance to thermal and cold shocks, and has a longer service life.
• Easy to install and maintain. The preformed lining of the filtration box is easy to replace, minimizing production downtime.
Main performance parameters of the CFB filtration box
- Maximum temperature of molten aluminum: 750°C
- Surface temperature: ≤70°C
- Lining life: ≥12 months
