23 6月 France China Foundry Filter
France China Foundry Filter can filter impurities such as hard aluminum slag in molten aluminum, so that the continuity of the aluminum ingot has been improved, and the mechanical properties have been improved.
There should be enough space before and after the CFF cast house to collect inclusions.
The molten aluminum alloy should be melted in a melting furnace (avoid oxidation and slagging treatment), and refining and degassing in a holding furnace.
Due to the limited filtering capacity of the filter, too dirty aluminum alloy liquid will cause the post-filtered aluminum alloy liquid to be more dirty than the first-filtered aluminum alloy liquid.
Precautions for using France China Foundry Filter
1. The filter is ceramic, so you must be careful when handling it to avoid bumps.
2. The debris in the filter must be blown off first, and then put it into the Ceramic Foam Filter For Metal Filtration holder.
3. After putting the filter into the filter holder, check that the top surface of the filter cannot be higher than the parting surface.
4. Store in a dry and ventilated place to avoid rain and excessive pressure.
5. Carry carefully to prevent collision and trampling during transportation.
6. If the shelf life exceeds 1 year, it is recommended to use it after drying.
There are many reasons for aluminum pollution
1.During the smelting process, the molten or semi-melted state of the atmosphere furnace exposed to aluminum is easy to oxidize, react with water vapor and absorb hydrogen, and it is easy to form various forms of non-metallic slag (such as lining fragments, chlorides, carbides in Changes, etc.) and coarse intermetallic compound particles.
2. Part of the waste that constitutes the cost brings some non-aluminum impurities in the recycling process.
Because the waste comes from process waste and waste from various processes in the factory, as well as waste outside the factory, the route is different, the composition is complicated, and the quality is poor.
The above-mentioned impurities often generate bubbles and inclusions in the casting slab, which seriously affects the purity of the molten metal, which in turn affects the processing performance, mechanical properties, corrosion resistance and appearance quality of the product.
France covers an area of 550,000 square kilometers (excluding overseas territories).
The total length of the border line is 5,695 kilometers, of which the coastline is 2,700 kilometers, the land line is 2,800 kilometers, and the inland river line is 195 kilometers.
Located in western Europe, bordering Belgium, Luxembourg, Switzerland, Germany, Italy, Spain, Andorra, and Monaco, facing the United Kingdom across the La Manche Strait to the northwest, bordering the North Sea, the English Channel, the Atlantic Ocean and the Mediterranean Sea. Corsica is the largest island in France.
The main mineral deposits in France are iron ore, followed by bauxite and potash ore.
The iron ore reserves are about 1 billion tons, but the grade is low, the mining cost is high, and the coal reserves are almost exhausted. All iron ore and coal mines have been closed, and the required ore is completely dependent on imports.
The reserves of non-ferrous metals are very small and almost all rely on imports. Energy mainly relies on nuclear energy, and about 78% of electricity is provided by nuclear energy.
In addition, the development and utilization of hydropower and geothermal resources are relatively sufficient. The forest area is about 15.565 million hectares, and the coverage rate is 28.6%.
