When the electrode needs to be replaced, the furnace must be shutdown, the electrode should be suspended from the conductive arm with a crane, and then the connected electrode should be hoisted to the conductive arm with a crane.

Disadvantages of traditional electrode manual off-line extension: time-consuming and labor-intensive, high labor intensity of workers, and uneven length of long-term connection length, easily damage the electrode thread.

In view of the above shortcomings, TYMEC has been considering how to achieve automatic electrode lengthening. No pains, no gains. At present, the automatic electrode extension device developed by TYMEC has been successfully operated.

Advantages of the electrode online automatic extension device: it can realize the automatic extension of the electrode at the heating station, which has high efficiency and can be operated automatically from a long distance, time and effort-saving, improving the working environment and shortening the electrode replacement time.

The electrode on-line automatic extension device has high operating efficiency, and the torque is even when the electrode is extended. The torque required during the extension can be adjusted to avoid the damage of the electrode thread and greatly reduce the probability of electrode breakage. This device greatly reduces the labor intensity of workers and saves labor costs.
