Graphite Electrode Usage Instructions
Before connecting the electrode, clean the electrode threads. Carefully screw the joint into one end of the electrode, and screw the hanging joint into the other end. Avoid collisions with the threads. It is not recommended to install the joint directly on the electrode in use on the furnace.
Do not clean the electrode threads with steel wool, metal brushes, or sandpaper. Only use oil- and water-free compressed air for cleaning.
Use a rotatable elastic hook and place a soft support pad under the electrode joint to prevent thread damage.
Before connecting the electrode, clean the hole with oil- and water-free compressed air.
Use an elastic hook to lift the electrode to the furnace, center it, and slowly lower it. Gently screw it in and tighten it with a hoop.
Use a specialized caliper to tighten the electrode to the specified torque. This can be achieved using mechanical, hydraulic, or pneumatic equipment.
Ensure the two electrode end faces are in proper contact. Insufficient or excessive contact pressure can affect performance. Refer to the torque specifications in the diagram.
The electrode holder must remain within the two white warning lines. Clean the contact surface between the holder and the electrode regularly to maintain good contact. Ensure the cooling water jacket of the holder does not leak.
To prevent electrode breakage, avoid loading insulating blocks into the furnace. Ensure the working current of the electrode is compatible with the allowable current specified in the manual.
To avoid electrode breakage, place large blocks at the bottom and small blocks at the top.
