Precautions when using graphite electrodes in EAF from annesheldon's blog

(1) Select the appropriate graphite electrode grade and diameter according to the capacity of EAF and transformer. 
(2) Avoid damaging and moistening during the process of loading, unloading and storage. Wetted electrodes should be dried. When lifting, needs to protect the electrode connector hole and the connector thread. 
(3) When connecting the electrode, use compressed air to blow off the dust in the connector hole. When the holder is holding the electrode, be sure to avoid the connector area. 
(4) The melting period is the most prone to break the electrode, so the operator should be carefully observed, timely lift the electrode. 
(5) In the refining period, if carbon is added by the graphite electrode, the electrode immersed in the molten steel becomes thinner quickly and breaks easily or causes the joint to fall, resulting in increased electrode consumption. Therefore, by other means to increase carbon as far as possible.
