Filter Box for Molten Aluminum

2021-09-15 17:21:16

The CFF filter box is widely used in the molten aluminum filtration in the aluminum melting and casting process, so as to filter the oxide slag in the aluminum liquid and prevent the particulate impurities from entering the casting slab, which affects the quality of aluminum processed products.

The CFF filter box can effectively filter out the large inclusions in the molten aluminum, adsorb small and small inclusions in the molten aluminum, refine the crystal structure of the casting, reduce the hydrogen content in the molten aluminum, and remove harmful elements in the molten aluminum through adsorption the content of Na and K.

Foam ceramic filter plates have been standardized and serialized in production. According to the requirements of the quality and flow of the molten aluminum, with filter plates with different hole sizes (20-60ppi) and filter plate combinations, different filtering effects can be achieved.

Ceramic Foam Filters are available in all common sizes: 7″, 9″, 12″, 15″, 17″, 20″, and 23″. We offer the whole range of porosities from PPI 10 up to PPI 60 (PPI = pores per inch). Custom-made cut-to-size filters are also possible.

Filter efficiency is related to filter cell size. By carefully controlling cell size within the filter, a more consistent filtration performance can be achieved. Typically, removal efficiency increases as filter cell size and the metal velocity in the filter decrease.

The ceramic foam filter plate has high strength, aluminum water erosion resistance, and good thermal shock performance, and the filter plate has a long life. The filter box equipped with a heating cover can ensure that the same filter plate is reused in the filtrate more than 6 times, reducing the cost of consumables. The lining of the filter box is similar to the degassing box, which is not infiltrated with aluminum, has good heat preservation, resistant to cold and heat shocks, and has a long life.
