By taking the following measures during the steelmaking process, electrode breakage and disconnection can be effectively avoided:
1.Correct Phase Sequence: Ensure the electrode phase sequence is correct, which should be in a counterclockwise direction.
2.Uniform Distribution of Scrap: Distribute scrap steel evenly in the furnace, placing large pieces of scrap material at the bottom.
3.Avoid Non-conductive Materials: Prevent the presence of non-conductive materials in the scrap steel.
4.Alignment of Electrode and Furnace Top Hole: Ensure the electrode column is aligned with the furnace top hole and that the electrode column is parallel. Frequently clean the furnace top hole walls to prevent accumulated slag from forcing the electrode to break.
5.Maintaining Furnace Tilting System: Keep the electric furnace tilting system in good condition to ensure stable tilting of the furnace.
6.Proper Electrode Clamping: Avoid clamping the electrode at the connection point or the electrode joint hole.
7.High-Strength, High-Precision Joints: Use high-strength, high-precision joints.
8.Appropriate Torque Application: Apply appropriate torque when connecting electrodes.
9.Protect Threads from Damage: Prevent mechanical damage to the electrode hole threads and joint threads before and during connection.
10.Prevent Foreign Matter in Electrode Holes: Prevent slag or foreign matter from embedding in the electrode hole and joint, which could affect the screwing connection.
