Zusammenfassung:	To provide an electrode vibration detection module (EVDM), and a method for detecting the vibration of an electrode in an electric arc furnace (EAF) using the EVDM.SOLUTION: Provided is an EVDM for receiving and/or confirming waveform signals corresponding to an electrode voltage measured between an electrode and the bottom part of an EAF outer shell and a voltage value and a current value associated with a current passing through the electrode, and is configured to identify the conditions of electrode vibration based on the waveform signals at least to some extent, to trigger alarms and/or to correct the operation of the EAF by adjusting the position of the electrode at the inside of the EAF.SELECTED DRAWING: Figure 1 【課題】電極振動検出モジュール（ＥＶＤＭ）、及び前記ＥＶＤＭを使用して電気アーク炉（ＥＡＦ）の電極の振動を検出する方法を提供する。【解決手段】ＥＶＤＭは、電極とＥＡＦ外殻の底部との間で測定される電極電圧（電極電圧）並びに電極を通る電流に関連付けられた電圧値及び電流値に対応する波形信号を受信及び／又は確認するものであり、その波形信号に少なくともある程度基づいて電極振動の条件を識別することと、アラームをトリガすること、及び／又はＥＡＦ内の電極の位置を調節することによってＥＡＦの動作を修正することと、を行うように構成されている。【選択図】図１
