Take the belowactions to avoid electrode break up, trip and over-oxidation during steelmaking
Adjust the phase sequence of electrodes. In the three-phase electric arc fumace, the phase sequence should be right of anticlockwise. Breakage will happen because of the loosing taken place because of the clockwise sequence.
Reduce the factures and breakages because of external mechanical force.material collapse in the fumace and improper operation. Load large pieces of steel material in the lower level of the fumace and distribute the scrap evenly.
Avoid non-conductive materials in the scrap; don’t put lime and other non-conductive objects gathering just right under the electrodes.
Attention to the lid position; Align the electrode columns with the roof hole and keep the electrodes column in parallel. Always keep the roof hole wall clean in order to avoid the accumulation of residual slag.
Maintain the furace tilting system in good condition so the fumace tilting remain stable.
Avoid clamping device holds electrode junction and nipple joint.
Protect the end faces of electrodes. Avoid bad connection because of end faces oxiclation and embed foreign object.
Protect the tips of electrodes and nipples thread from mechanical damage before and during connecting of electrodes.
Prevent slag or foreign objects embedding the surface of electrodes and nipples which will affect the threading in; blow the surface with compressed air before connection.
Reduce the consumption of oxidation of the electrode perimeter to enhance the sealing of the fumace in order to reduce air intrusion. Minimize the exposure time of the hot electrodes outside the fumace. Appropriate operation of oxygen blowing.
Selecet nipple of good quality and good machining accuracy, avoid mixed using nipples from several suppliers.
Suggest to take spray cooling technology for melfing fumace; it can effectively reduce the oxidative consumption of the surface of electrodes.
