How should steel mills properly store and handle 200mm diameter graphite electrodes?
Graphite electrodes are brittle and sensitive to bumps and moisture. Improper storage and handling can result in serious damage:
• Storage: They must be stored in a dry, flat warehouse with sleepers placed underneath. The number of stacking layers is strictly limited. Open-air storage, where they may be exposed to rain and moisture, is strictly prohibited.
• Handling: Special lifting equipment (such as flexible nylon slings) must be used. Direct hooking or lifting with wire rope is strictly prohibited. Prevent any collision, drop, or rolling.
• Pre-use Inspection: Before use, inspect the threads and body for cracks, bumps, or other damage. Wet electrodes must be dried before use; otherwise, they will burst instantly when placed in a high-temperature furnace.
