19 8月 Ceramic Foam Filter Nazan Aluminium
Ceramic Foam Filter Nazan Aluminium is a method of filtering out impurities, gases and certain harmful elements in the aluminum melt through a filter (body) in the process of casting or casting salt.
The principle is adsorption filtration and mechanical filtration.
The mechanical properties of aluminum alloy filter castings are greatly improved, and the strength, toughness and elongation can be improved.
After the molten aluminum is filtered, the quality of ingots and castings has also been significantly improved.
There are many lead melt filter materials, such as glass cloth, refractory fiber mesh, magnesium fluoride, calcium fluoride and so on.

Inclusions are any solid or liquid foreign impurities that exist above the liquidus temperature.
Common non-metallic inclusions include oxides, carbides, borides and so on. In addition, some undesirable intermetallic compounds appear in high alloy melts.
Non-metallic inclusions in lead melt include:
1. Oxides: aluminum oxide, magnesium oxide, calcium oxide, etc.
2. Coarse Ti-B particles of residual refiner Al-Ti-B master alloy.
3. Protective coatings on refractory brick fragments, sinks and tools.
Aluminum and its alloys are easy to oxidize and get gas in the process of smelting and pouring, and defects such as inclusions and pores are easily formed in the process of aluminum rods and ingots, which are unfavorable to the alloy structure, thereby reducing the mechanical properties and corrosion resistance of the alloy, and reducing the finished product Rate.
Therefore, reasonable control of the smelting process and improvement of the quality of the aluminum melt are the key to improving the quality of aluminum die castings.
When choosing Ceramic Foam Filter Nazan Aluminium, you must pay attention to the following issues.
1. The production grade of aluminum alloy.
2. The throughput of molten aluminum.
3. The required filtering accuracy.
