Molten Aluminum Filter Sual Aluminium is used for melting and recycling aluminum scrap in aluminum factory processes.
When cutting metal castings, chips account for about 20% of the weight of the casting, up to about 30%. Aluminum shavings can reduce production costs during product processing and have good economic benefits.
The purpose of aluminum scrap pretreatment technology is to realize the mechanization and automation of aluminum scrap separation, maximize the removal of metal and non-metal impurities, and realize the efficient separation of aluminum scrap.
The ideal separation method for aluminum scrap is to divide aluminum scrap into several categories according to the basic alloy composition, such as aluminum alloy, aluminum-magnesium alloy, aluminum-copper alloy, aluminum-zinc alloy, aluminum-silicon alloy, and so on.
It can reduce the difficulty of removing impurities and adjusting the composition in the smelting process, and can also use a large amount of alloy components in the scrap aluminum, especially the aluminum scrap with high zinc, copper, and magnesium content, which must be stored separately and can be adjusted as a molten aluminum alloy. Composition of raw materials.
Casting filter used in the melting and purification process of aluminum scrap.
There are generally two methods of melting aluminum shavings.
Double melt
1. Smelt scrap aluminum into ingots (recycled ingots) and stack them according to their chemical composition.
2. Mix the recovered steel ingots into the furnace during smelting to melt the finished product.
RUSAL plans to substantially increase its aluminum supply to China next year. The company expects output will be restricted and China’s aluminum shortage will continue.
China is the world’s largest consumer of aluminum. Some provinces and regions restrict the use of electricity in energy-intensive industries such as aluminum smelting, which has caused a shortage of aluminum in China this year.
Roman Andryushin, the sales director of RUSAL in Russia, CIS and China, said that RUSAL is the world’s largest aluminum producer outside of China and plans to supply 300,000 to 400,000 tons of aluminum to China in 2021. Stabilize at the level of 2020, and substantially increase sales next year.
China is the world’s largest aluminum producer and has almost no demand for overseas supply. The rapid recovery of demand after the coronavirus outbreak meant that China had to import a record amount of aluminum last year. On Thursday, global aluminum shortages pushed prices up to US$3,169 per ton, the highest level since July 2008.
Andryushin said that thanks to the planned launch of the Taishet smelter, Rusal’s total aluminum production in 2022 will rise to about 4.3 million tons. Rusal will produce 3.8 million tons in 2020. It is estimated that after a surplus of 1.4 million tons in 2020, the global aluminum market gap will exceed 1.5 million tons this year. “We expect that the shortage will be even greater next year because all economies expect higher demand. I believe that in the long run, China will face a shortage.” Scrap aluminum recycling and primary aluminum imports should help make up for China’s gap . China will work hard to buy low-carbon aluminum. “
