Design experimental electromagnetic stirrer @hebei

           Compared with other mixing way, electromagnetic stirring compatible with the other mixing way’ advantages, and has its own unique characteristic, therefore, electromagnetic stirring has become the common use stirring method.             Effect of stirring             To adopt the advanced technology of electromagnetic stirring, through lots of experiments and industrial production at home and abroad by using electromagnetic stirring main effect achieved:             Reducing slag content;             Reduce the center shrinkage cavity;             Eliminate the macrosegregation;             Increase the equiaxial crystal ratio;             Improve solidification organization, etc.               basic parameter             Frequency conversion form: AC-DC-AC             The input voltage: three phase 380V or single phase 220V  50HZ             Power input capacity: 2-80KVA             The power output capacity: 2-120KVA             Output frequency: 5-30HZ             Output voltage: 0-380V(220V)             Output current: 0-180A             Work style: Continuous adjustable frequency, in stir working condition can adjust the voltage and current.             Magnetic field forms: A rotating magnetic field or traveling wave magnetic field             Mixing ability: 0.5-50Kg                 Electromagnetic stirring has the following characteristics:             (1)the electromagnetic stirring and liquid with no physical contact, do not pollute the liquid aluminum, it has great significance in melting high purity aluminum and alloy research.             (2) it can effectively solve the problem of uniformity of alloy composition, in some cases it can reach the effect which artificial mixing could not.             (3) Does not destroy oxide layer mixing, thus can reduce the oxidation slag, to reduce the burning loss rate.             (4)Stirring direction and stirring intensity can be adjusted             (5) A one-time investment, the cost is low, save energy, enhance productivity.             (6)Simple and convenient for operation and maintenance
