摘　　要：通过电热信号监测系统,采集铝电解槽各短路母线和大电流多级变阻装置的电流数据,基于毕奥-萨法尔定律,可模拟并总结出单一状态下目标施焊区域的磁场矢量,以及随大电流多级变阻装置组的电流变化规律,从而得到此状态下施焊区域最优降磁效果的控制电流组合,将所有状态关联并组合,最终形成带电焊接全过程控制专家系统。By using an electro-thermal signal monitoring system,the current data of each short-circuit busbar and high current multi-stage variable resistance device in an aluminum reduction cell can be collected.Based on the Biot Savart law,the magnetic field vector of the target welding area in a single state and the current variation pattern with the high current multi-stage variable resistance device group can be simulated and summarized.Therefore,the optimal control current combination for the demagnetization effect in the welding area in this state can be obtained,and all states can be correlated and combined.Finally,an expert system for the entire process control of live welding will be formed.
