Main factors affecting the consumption of graphite electrodes in EAF steelmaking
There are three kinds of semi-finished products of graphite electrodes.
The main reasons for the loss and consumption of graphite electrodes are overload and overtime operation.
Low quality or improper proportion of scrap results in poor slagging effect and prolonged smelting time.
Increasing the number of feeding operations increases the probability of damage and fracture at the bottom of the electrode.
Mismatch between the power supply equipment of the electric furnace and the electrode specifications.
The choice of power curve and gear, the control of arc starting and arc stabilizing voltage and current, the use of long, medium and short arcs, and the configuration of the water cooling system are all important for the service life and consumption of the electrode.
The quality of graphite electrodes themselves affects the consumption rate. Nowadays, the electric arc furnace smelting process has higher and higher requirements for the anti-oxidation performance and thermal shock resistance of graphite electrodes, and the high consumption caused by quality fluctuations has also attracted great attention from users. Therefore, the uniformity and stability of graphite electrodes are the most important factors determining consumption.
