Porous Sintered Ceramic Foam Filter
The quality of the aluminum melt is important, which greatly affects the subsequent processing properties and the quality of the final product.
Therefore, all countries in the world attach great importance to the purification of aluminum melt.
There are many reasons for aluminum pollution. On the one hand, during the melting process, aluminum is exposed to the furnace atmosphere in a molten or semi-molten state, which is prone to oxidation, easily reacts with water vapor to absorb hydrogen, and easily forms various forms of non-metallic slag. (such as lining debris, chlorides, carbides, etc. in the flux) as well as coarse intermetallic particles and the like.
On the other hand, part of the waste material in the composition charge carries some non-aluminum impurities during the circulation.
Since the waste comes from the process waste and waste of the various processes of the factory and the waste outside the factory, the route is different, the composition is complex, and the quality is also poor.
These impurities tend to cause bubbles and inclusions in the slab, which seriously affect the purity of the metal melt, thereby further affecting the processing properties, mechanical properties, corrosion resistance and appearance quality of the product.
Porous Sintered Ceramic Foam Filter supplied by our company can effectively remove all kinds of fineness in the aluminum water to the micron-sized inclusions, and make the aluminum water become a smooth laminar flow, which is favorable for filling.
It has good mechanical strength and chemical stability, and superior aluminum washability.
Strictly controlled hole size and through-hole ratio for stable filtration.
The foam ceramic filter plate is surrounded by a sealed heat-expandable ceramic fiber gasket, which helps the filter plate to seal in the filter box, ensuring no metal liquid bypass.
After using the foam ceramic filter plate to purify the aluminum liquid, it brings great benefits to the strip foil and its products (such as cans, sequins for cars, PS printing plates, etc.), as for the manufacturers of aluminum alloy profiles, Here are a few obvious advantages:
1. Increase extrusion productivity
2. Extend mold life and reduce the number of mold repairs.
3. Reduce the pressing force
4. Significantly improved the surface quality of the aluminum profile.
