Production Cycle of Graphite Electrode

In general, the whole production process without discontinuity, from raw material process to the finished product, need about 60 days at the fastest.The production of the graphite nipple is about 90 days at the fastest because the nipples need two times impregnation and three times baking.

Production Process

Normally, the process and corresponding time of the production of a batch of ultra-high power or high-power graphite electrodes are as follows:
• Extrusion Forming (3 days)
• Primary Baking (25 days)
• Impregnation (4 days)
• Secondary baking (15 days)
• Graphitization (10 days)
• Machining / quality inspection (2 days)
• Finished packaging (1 day)

Production Cycle

How long does it take to produce HP/UHP graphite electrode?
The graphite electrode has many production processes and a long production cycle.
The production cycle of ordinary power graphite electrode is about 45 days;
The production cycle of ultra high power graphite electrode needs more than 75 days;
The production cycle of graphite nipples is much longer about 90 days.
