摘要

为了更好地了解冷坩埚内部电磁场分布对玻璃固化的影响

利用有限元分析软件ANSYS对玻璃固化用小型电磁冷坩埚进行3D建模

对冷坩埚的电磁场进行运算。通过对不同路径、电流、频率下冷坩埚内部的磁场分布的比较

并利用实际测量值进行验证。结果发现

在空载条件下线圈中部位置的磁感应强度最大

随着高度变化向两端递减。随电流从500A增大到1 500A

磁感应强度增强。随频率由50kHz升至200kHz

磁感应强度降低。

Abstract

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.
