Graphite electrode-Effect of Phase Sequence on Electrode Release of EAF

Electrode Consumption Influencing factors

Electrode Consumption Influencing factors main as below:

1.Around the electrode,magnetic field would be generated under the action of sine wave exchange current when making steel by three phase AC EAF.The resultant magnetic field of three phase electrode is rotary which can make an electromagnetic force at the tangential direction of circle.The direction of this force is same as three phase current phase sequence.

2.For the single phase electorde, the electrode at the holder part is fixed, and under which anticlockwise is the electrode tighten direction and the opposite is loose(up-down)

3.When three phase electrode sequence(i,e, Three phase current sequence) is clockwise, the resultant electromagnetic force could also be clock wish which is same as the electrode loosen direction.Therefore,electrode could easy to get loose when power on

4.When three phase electrode sequence is anticlockwise, the resultant electromagnetic force could also be anticlockwise which is same as the electrode tighten direction. Therefore, the more used, the tighten the electrode will be

5.Electrode loose is easy to cause electrode fall off and nipple broken which lead to abnormal situations when steel making.

6.The correct electrode(current) phase sequence is anticlockwise.If electrode loose when using, you could first stop refining and then check the electrode by phase sequence meter in the charged case to make it clear whether phase sequence is correct or not. If not,you just need to exchange two phase of incoming cable or cable outlet in high voltage switch cabinet at will. You can also contact our professionals to measure and adjust for you
