17 x17 x2inch Alumina Ceramic Foam Filter Plate For Alumina Ingot

There are many reasons for aluminum pollution:

1, in the smelting process, aluminum is exposed to the furnace atmosphere in a molten or semi-molten state, easy to oxidize, easy to react with water vapor and absorb hydrogen, easy to form various forms of non-metallic slag (such as furnace lining debris, chloride, carbide in flux, etc.) and coarse metal intercompound particles and so on. 

2, part of the waste that makes up the charge brings some non-aluminum impurities into circulation.

Influence to Aluminium Liquid:

1, Because the waste is coming from the process waste and scrap during each process in factory and the waste outside the factory, so, the composition is complex due to different way as well as the quality is poor. 

2,These impurities often make the billet produce bubbles and inclusions, which seriously affect the purity of the metal melt, thus further affect the processing properties, mechanical properties, corrosion resistance and the appearance quality of the product.

How to solve above problems:

● Alumina foam ceramic filter plate can effectively remove all kinds of inclusions with fineness up to micron level in aluminum liquid, make aluminum liquid into a steady laminar flow, which is conducive to filling. 

● It has a unique mullite-corundum structure, good mechanical strength and chemical stability, excellent resistance to aluminum liquid erosion performance.

● It can obtain stable filtration effect by strict control of hole size and through hole rate.

● The ceramic foam filter plate is surrounded by a sealing ceramic fiber liner, which facilitates the seal of the filter plate in the filter box to ensure that there is no metal liquid sideflow.
