Experiment study of magnetic field wave with the board base electromagnetic stirrer

根据板坯行波电磁搅拌器的特点,在实验室采用三维高斯计对行波磁场电磁搅拌器的磁场变化规律进行了测量,得到大量的实测数据.研究分析表明,对于所研究的行波磁场电磁搅拌器,频率、电流强度以及磁极间距离对磁感应强度影响很大,其中,频率增大,磁感应强度有所降低,电流增大,磁感应强度线性增大,而磁极间的距离对磁感应强度也有明显的影响,这些结果为进一步研究行波磁场电磁搅拌器的变化规律积累了数据.

The law of magnetic field change of travelling wave electromagnetic blender with three-dimensional Gauss meter was measured according to the characteristics of strip travelling wave electromagnetic blender, and lots of measured data were obtained. Researches and analyses indicate that frequency, current intensity and distance between magnetic poles greatly affect the magnetic induction for the travelling wave electromagnetic blender researched herein. Magnetic induction drops when frequency increases,while the linearity of magnetic induction increases accordingly with increasing the current. The distance between magnetic poles can also influence the magnetic induction. These results provide us with data for fu/ther researching the law of magnetic field change of travelling wave electromagnetic blender.
