Alumina foam ceramic filter plate produced by our company can effectively remove the fineness of aluminum water to reach the inclusion of micron grade, make aluminum water into stable laminar flow, and facilitate filling. It has a unique mullite corundum structure, good mechanical strength, and chemical stability, superior aluminum water scouring performance, and strict control of hole size and through-hole rate can achieve stability. There is a sealed ceramic fiber liner around the alumina foam ceramic filter plate, which helps to seal the filter plate in the filter box and ensure no metal liquid side flow. The ceramic foam filter product is mainly used in the purification process of aluminum and aluminum alloy production, as well as various gas-solid, liquid-solid separation media, catalyst carrier, burner and sound-absorbing environmental protection fields.
The quality of aluminum melt is very important, which affects the subsequent processing performance and the quality of the final product. Therefore, countries all over the world attach great importance to the purification of aluminum melt. There are many reasons for aluminum pollution.
On the one hand, in the smelting process, aluminum is exposed to the atmosphere in the furnace in a molten or semi molten state, which is easy to oxidize and react with water vapor to absorb hydrogen. It is easy to form various forms of non-metallic slag inclusion (such as furnace lining fragments, chlorides and carbonates in flux) and coarse metal intermetallic particles.
On the other hand, some non aluminum impurities are brought in during the circulation of some wastes in the charge. As the waste comes from the process waste and waste materials of various processes in our factory and the waste materials outside the plant, the way is different, the composition is complex and the quality is poor. These impurities often cause bubbles and inclusions in the slab, which seriously affect the purity of the molten metal, and further affect the processing performance, mechanical properties, corrosion resistance and appearance quality of the products
