      永磁除鐵器及永磁攪拌器技術原理

      Permanent magnetic separators and permanent magnetic stirrer technology principle

      該產品可廣泛應用于有色金屬冶煉過程中的非接觸式攪拌,特別是對鋁合金冶煉應用更為方便,該產品體積小、重量輕,使用靈活,工作可靠。隨著我國冶金行業的不斷擴大,永磁攪拌器將不斷取代機械式攪拌、手工攪拌、電磁攪拌等,是一種節能、環保、高效新產品。

      The product can be widely used in non ferrous metal smelting process, especially in the aluminum alloy smelting application more convenient, the product is small size, light weight, flexible use, reliable work. With the continuous expansion of China's metallurgical industry, permanent magnetic stirrer will continue to replace mechanical agitation, manual mixing, electromagnetic stirring, etc., is a kind of energy saving, environmental protection, efficient new products.

      該產品是靠永磁體所產生的磁力場對有色金屬液體進行非接觸式攪拌,永磁攪拌器是根據異步電動機的原理制作的,它就相當于一臺氣隙很大的使用永磁體磁場的電動機,磁感應器相當于電動機的定子,有色金屬熔液相當于電動機的轉子,磁場和熔池中的有色金屬液相互作用產生感應電勢和感生電流,這種感生電流又和磁場作用產生電磁力, 從而推動有色金屬液體作定向運動,起到攪拌作用,攪拌速度和間隔時間可根據不同有色金屬液體調整。

      The product is by the magnetic force produced by the permanent magnet field of nonferrous metal liquid non-contact stirring, permanent magnetic stirrer is made according to the principle of asynchronous motor, it uses the equivalent of a large air gap magnetic field of permanent magnet motor stator magnetic inductor equivalent motor, the rotor of nonferrous metal is in the motor, the nonferrous metal liquid in the molten pool and the magnetic field produced by the interaction of EMF and induced current, the induced current and magnetic field and electromagnetic force, so as to promote the non-ferrous metal liquid as the directional movement, to stir effect, stirring speed and time interval according to the different nonferrous metal liquid adjustment.

      通過對有色金屬液體的正反轉交替攪拌,使有色金屬液體在正反轉過程中產生渦流,可獲得充分均勻的攪拌效果。永磁攪拌器由于是非接觸式攪拌,不會污染溶液,由于磁感應器置于流槽池的底部,熔體底部的合金熔液獲得的攪拌力較大,頂部的攪拌力較小,即表面的氧化膜不易被破壞,有效減少合金溶液的表面氧化,同時減少熔體吸氣,防止成份突變,得到高質量的熔體。

      Through the positive and negative alternation of the non ferrous metal liquid, the liquid metal can generate eddy current in the process of positive and negative inversion. Permanent magnetic stirrer is due to non-contact stirring, does not pollute the solution, because the magnetic inductor is placed at the bottom of the pool chute, the molten alloy melt at the bottom of the stirring force is larger, smaller at the top of the stirring force, namely, the oxide film on the surface is not easy to be destroyed, effectively reduce the surface oxidation of alloy solution, while reducing melt suction, prevent composition of mutation, melt quality.
