The reasons for frequent failures of ET-DecNT electric furnace electrode regulation control system in the later period of service life were analyzed,and the electrode regulation system based on Siemens S7-1500PLC hardware was constructed.The equipment of Siemens S7-1500 series PLC electrode regulation system was stable and reliable,and the maintenance was more convenient.Eliminate backward production technology and adopt advanced impedance control concept.Calculate the best working point of transformer gear impedance,optimize smelting control model,improve the control characteristics of electrode regulator,improve the optimal arc power of electric furnace in different smelting stages,improve the smelting efficiency of electric furnace,save energy and reduce consumption,and solve the problem of hardware elimina-tion and supply failure of the original system.
