Sweden China Foundry Filter is very important to the quality of the aluminum melt, and it greatly affects the subsequent processing performance 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 smelting process, aluminum is exposed to the atmosphere in the furnace in a molten or semi-molten state. It is prone to oxidation, reacts with water vapor to absorb hydrogen, and easily forms various forms of non-metallic slag. (Such as lining fragments, chlorides, carbides in flux, etc.) and coarse intermetallic particles, etc.
On the other hand, part of the scraps that make up the charge brings some non-aluminum impurities in the circulation process.
Because the waste comes from the process waste and waste material and off-plant waste material in each process of the factory, the route is different, the composition is complicated, and the quality is poor.
The above-mentioned impurities often cause bubbles and inclusions in the casting slab, which seriously affect the purity of the molten metal, thereby further affecting the processing performance, mechanical properties, corrosion resistance and the appearance quality of the product.

Sweden China Foundry Filter use effect: the use of aluminum oxide filter to purify the aluminum liquid brings great benefits to the strip foil and its products (such as can blanks, car finishing materials, PS printing plates, etc.). For manufacturers, there are several obvious advantages:
1. Increase extrusion productivity
2. Extend the life of the mold and reduce the number of mold repairs.
3. Reduce squeezing force
4. Significantly improve the surface quality of aluminum profiles.

Sweden is located in the eastern part of Scandinavia in Northern Europe, borders Finland to the northeast, Norway to the west, the Gulf of Bothnia and the Baltic Sea to the east across the sea from Russia, and the North Sea to the southwest, and borders Denmark and the United Kingdom. Across the sea.
The territorial area is 449964㎞² (not including the territorial sea area). The territorial sea has 12 nautical miles, the coastline is about 2,181 kilometers, and about 15% of the land is in the Arctic Circle.

Iron ore, forests and water power are Sweden’s three major resources.
As of 2014, Sweden has proven iron ore reserves of 3.65 billion tons, making it Europe’s largest iron ore exporter. Uranium reserves range from 250,000 to 300,000 tons.
The forest coverage rate is 54%, and the storage material is 2.64 billion cubic meters.
The available hydropower resources in the year are 2014 million kilowatts (176 billion kilowatt-hours), 81% of which have been developed. In addition, there are sulfur, copper, lead, zinc, arsenic and other mines in the northern and central regions, and the reserves are not large.
