To better understand the internal electromagnetic field distribution in cold crucible on melting and solidifying glass

the ANSYS software was used to establish 3D model for small electromagnetic cold crucible for glass solidification

and the electromagnetic field in cold crucible was calculated.By the comparison of different paths

electric current

frequency of the magnetic field distribution inside the cold crucible

and actual measurement values were used to validated.The results show that the maximum magnetic field intensity in the central position of no-load condition can be obserbed and it is decreased gradually to two side with height difference.The magnetic field intensity is enhanced as the current increased from 500 Ato 1 500 A

while it decreases with the frequency increasing from 50 kHz to200kHz.
