Metal ceramic foam filters are best way
-
Australia Foundry ceramic foam filter effectively removes various oxide inclusions generated during aluminum smelting through physical adsorption and chemical action, thereby reducing casting defects, improving casting quality, and providing high-quality aluminum. It is suitable for the purification process of aluminum and aluminum alloy with high production requirements.
Metal ceramic foam filters are best way to eliminate non-metallic inclusions in aluminum solution. These inclusions are the main source of casting quality problems.
When casting products, remove impurities in molten metal, refractory waste, solid refractory alloys and sintered ore, eliminate turbulence, reduce porosity of castings, and improve casting quality.
Therefore, our metal foam filters are widely used in the aluminum casting industry to prevent defects such as oxides, scum, gas, slag and other impurities.
The turbulence in the metal flow is eliminated, the metal flow is stabilized, and spray, splash and collapse are avoided. Improve fluidity, castability, processability, yield and cost-effectiveness. Remove a larger proportion of fine particles, reduce waste, rework, and low pressure loss. Provide consistent flow and capacity.
There are many reasons for aluminum pollution
On the one hand, during the refining process, the molten or semi-melted state of the atmosphere furnace exposed to aluminum is easy to oxidize, easily react with water vapor to absorb hydrogen, and easily form various forms of inclusions (such as lining fragments, chlorides and carbides in Constant changes, as well as coarse intermetallic compound particles.
On the other hand, part of the waste that constitutes the cost brings some non-aluminum impurities in the recycling process. Because the waste comes from process waste, geometric waste, and off-site waste in each process of the factory, the route is different, the composition is complicated, and the quality is poor.
According to the Austria Aluminum Company, the Australia China Foundry Ceramic foam Filter can effectively remove large impurities from molten aluminum and effectively absorb small impurities. This product is recommended to other aluminum plants in Norway. The feedback from the factory floor is as follows:
1. No debris, effectively reducing the pollution of molten aluminum.
2. Excellent thermal shock resistance improves the erosion resistance of molten metal.
3. Improve the surface appearance and performance of molten aluminum, and purify molten aluminum.
Australia is located between the South Pacific and the Indian Ocean and consists of islands and overseas territories such as the Australian mainland and Tasmania.
It faces the Coral Sea and Tasman Sea in the east of the Pacific Ocean, and faces the Indian Ocean and its marginal seas in the west, north and south.
It is the only country in the world that monopolizes a continent.
Australia is rich in mineral resources, oil and natural gas, and there are at least 70 kinds of mineral resources.
Among them, bauxite reserves rank first in the world, accounting for 35% of the world’s total reserves.
Australia is the world’s largest producer of bauxite, alumina, diamonds, lead, and tantalum. The output of gold, iron ore, coal, lithium, manganese ore, nickel, silver, uranium, and zinc is also among the world’s top producers.
At the same time, Australia is the world’s largest exporter of bituminous coal, bauxite, lead, diamond, zinc and concentrates, the second largest exporter of alumina, iron ore, and uranium ore, and the third largest exporter of aluminum and gold.
