Effect of Current Frequency on Droplet Evolution During Magnetic-Field-Controlled Electroslag Remelting Process Via Visualization Method

A transparent physical model was set up to investigate the influence of the remelting current frequencies on droplet evolution during the magnetic-field-controlled electroslag remelting process. Physical simulation experiments were done under the remelting current of 8 A with frequencies ranging from 10 to 500 Hz, and a transverse static magnetic field (TSMF) of 0.7 T was superimposed simultaneously. The high-speed camera was used to record the...
