System Composition of electromagnetic stirring

              Electromagnetic Stirrer is composed of AC-DC-AC inverters, inductors, pure water-cooled devices (water-wind type), functional trolley and appurtenances. The function of AC-DC-AC inverters is to convert 50/60Hz industry frequency alternate current (AC) into a 0.5 ~ 5.0Hz, 3-phase low-frequency power. The power through sensor coil, will produce a traveling magnetic field, which penetrating stainless steel plate of the bottom of furnace and lining effect on molten aluminum, make molten aluminum regular movement, finally achieved the purpose of even stirring. By changing the voltage, frequency and phase of the variable frequency power supply, you can change the magnitude and direction of the stirring force.                          In the primary aluminum used in the production process of electromagnetic stirring technology ,the most main purpose is to make the aluminum alloy melt liquid components uniform, and on the waste recycling technology’s main purpose is to improve the melting effect, to reduce the loss and increase casting yield. Of course, since the noise components of the waste aluminum was more complex, long time mixing for composition adjustment and composition of the improved uniformity is particularly important. We shall, according to the different purpose reasonable setting of electromagnetic stirring device installation position sensors, either party furnace, the furnace, single room or a double room furnace, the installation of sensors can be roughly divided into bottom buy and side for two kind of way, buy the installation is mainly used for the new furnace form or depth of molten pool in the production process change the big furnace, this form melting liquid depth change effects and can achieve good mixing effect, in waste recycling aluminum furnace installation position to deviation furnace center, so can form the whole furnace big, help to fast melting scrap aluminum. Sensors installed side is mainly used for old furnace way transformation and molten pool depth in the production process change less than 200 mm.                         Inductive electromagnetic stirring device is a kind of application principle of electromagnetic induction and produce a magnetic field in the role of molten aluminium liquid so that melting liquid has regular exercise equipment. In the electromagnetic stirring subject device-to low frequency current of sensors, in order to form the traveling wave alternating magnetic field, melting liquid in the influence of the magnetic field of potential and current, the induced current and magnetic fields interact to produce the electromagnetic force, make the melting liquid regular exercise, in order to achieve the purpose of mixing. By changing the direction of the field and the traveling wave strength, can effectively regulate the melting liquid mixing direction and stir intensity.
