- 1.Adjust the electrode phase sequence, ensuring it follows a counterclockwise direction in AC EAF.
- 2.Distribute scraps evenly in the furnace, placing larger pieces at the bottom.
- 3.Avoid mixing non-conductive materials with scraps or accumulating them, such as lime, directly under the electrodes, as this affects electrical conductivity and may cause breakage.
- 4.Ensure the electrode columns align with the furnace roof hole and remain parallel. Keep the furnace roof hole walls clean to prevent residual slag accumulation.
- 5.Maintain the furnace tilting system to ensure stability.
- 6.Avoid placing clamps at connecting or socket positions.
- 7.Do not mix electrodes and nipples from different manufacturers, as their chemical and physical properties may vary due to differing raw materials and production processes.
- 8.Keep the electrode end surfaces clean, free from oxidation and impurities, to ensure a solid connection.
- 9.Prevent mechanical damage to the electrode socket and nipple threads before and during connection.
- 10.Clean the electrode socket and nipple surfaces thoroughly, removing slag and impurities by blowing compressed air before connection.
- 11.Seal the furnace well to reduce electrode oxidation consumption and minimize the exposure time of hot electrodes outside the furnace.
- 12.Use a spray cooling device to effectively reduce surface oxidation consumption in LF.
- 13.Always use the recommended torque and wrench settings for connections.
