The production process and corresponding time for a batch of ultra-high power or high-power graphite electrodes are as follows: electrode pressing (3 days) - baking (25 days) - immersion (4 days) - re baking (15 days) - graphitization (10 days) - machining and quality inspection (2 days) - finished product packaging and shipping (1 day). The fastest production cycle without interruption from feeding to product shipping is also 60 days, while the production cycle for electrode joints is as fast as 90 days due to the two immersion and three baking treatments required compared to electrodes.
