Aluminum Plate Foundry Filter

Aluminum Plate Foundry Filter is an advanced product used for molten metal secondary refining. It has a porous structure network. With the continuous deposition of fluid inclusions, the size of the sieve holes and sieve holes becomes smaller and smaller, thereby improving the filtering effect.

The type of CFF metal filtration can be divided into deep bed filtration, filter cake filtration, or mixed filtration. The efficiency depends on the pore PPI (pores per inch) of the filter material. It is also related to the size distribution of the removed particles. PPI refers to the plastic used to make foam ceramics. The number of pore boundaries encountered per inch can be found from the average value.

The filtration parameters of Aluminum Plate Foundry Filter are effective porosity (that is, the porosity that effectively affects the porosity), fluid tortuosity, specific surface area and pore size.

Molten metal filtration requires good chemical stability and excellent filtration function, especially the collection and absorption of 1-10um small impurities and filtration residues. The CFF three-dimensional structure can greatly improve the quality of the casting by changing the molten metal from turbulent flow to laminar flow, removing gas, and smoothing the casting.

The CFF metal filtration process also depends on alloy type, grain refiner, casting rate, metal temperature, and so on. Adding a grain refiner before the Ceramic Foundry Filter has a particularly adverse effect on the filtration efficiency.

In terms of cost and ease of use, ceramic foam filters (CFF) are generally considered to be the “best” placement filter with acceptable performance characteristics. Their main advantages are high filtration efficiency, low turbulence, high refractoriness, corrosion resistance, and suitable for the most demanding casting applications.

Our ceramic foam filter use good portiforium foam and high purity ceramic as raw material, can removes non-metal solid mixture from molten aluminium and aluminium alloy effectively in your aluminium casting industry. Using the right High-Temperature Materials will affect your productivity in a positive way!
