RP Graphite Electrode Production Process
Recommended Guideline For Transport And Storing
1.Operate carefully to prevent slipping due to the tilt of the electrode and breaking the electrode;
2.In order to ensure the electrode end surface and electrode thread, please do not hook the electrode at both ends of the electrode with an iron hook;
3.It should be taken lightly to prevent hitting the joint and causing thread damage When loading and unloading;
4.Don’t pile the electrodes and joints directly on the ground, Should put on the wooden or iron frame to prevent the electrode damage or stick to the soil, Do not remove the packaging before use in order to to prevent dust, debris falling on the thread or electrode hole;
