Nowadays, electromagnetic stirring technology is quite mature, and it is not widely used in various industries, but this time there is a new breakthrough. Researchers have found that electromagnetic stirrer can also play a big role in the aluminum industry. Electromagnetic stirrer can be changed by changing The size of the current can adjust the stirring force, and the phase of the two-phase current can be changed to change the stirring direction, so the stirring is convenient and sufficient, and the temperature of the melt and the alloy composition are uniform. At present, the inventory in the domestic futures market is actually saturated, and the amount of change in inventory can no longer reflect changes in industry supply and demand. The national alumina cost varies slightly depending on the region and the source of the ore used. Because Shandong enterprises use a large amount of imported bauxite from Indonesia, the cost of ore per ton of alumina is about 240 US dollars, and the actual cost of alumina per ton is more than 3,000 yuan; the cost of alumina enterprises using domestic ore in Henan is 2700-2800 yuan. ; Shanxi is lower.
This can be well used in aluminum melting and casting. The use of this property of the electromagnetic stirrer can help aluminum fully dissolve and mold, and it has a practical effect. The benefits are also very obvious. For example, it will not pollute the melt, it can be fully stirred, the temperature can be effectively controlled, and the oxidation of gold can be reduced. This is a great improvement over the traditional casting solution.
Through this technological innovation, the processing cost of aluminum has been reduced and the quality has been significantly improved.
