Cause of electrode breakage
◆ The force state of the electrode, the degree of force from top to bottom decreases in turn, and the electrode and joint located below the gripper receive the greatest force. ◆ When the electrode is subjected to external force: the external force of stress concentration leads to electrode breakage. ◆ The causes of external force include: collapse of large furnace charge during melting period, non-conductive object at the lower end of electrode in scrap steel, impact of massive flow steel, etc. ◆ Uncoordinated lifting response speed of electrode holder, eccentric core of electrode hole of furnace cover, poor electrode connection, gaps at joints and joints with substandard use strength are also easy to break. ◆ electrode and joint processing accuracy is poor, resulting in poor coordination, but also easy to cause
