Electrocode Control System
In the field of electric arc furnace construction, the electrode regulation system assists in regulating arc impedance, resistance and voltage, while an additional loop helps to ensure controlled power. The control module will help to compensate for any variations that have resulted from the up and down movements. For LF applications we provide an anti-resonance device which will help to counteract the possible fluctuating overtones on the surface of the refractory bath.
Optimisation system
The system available helps save energy while protecting the furnace and vault gasket better taking into consideration the cooling water in both the panels and the vault, and protecting the total harmonic distortion and the position of the columns and flickers. The system reduces any leaks from the arc in hot spots by modifying the respective setting values. To compensate for the impact of the other two electrodes, their setting has also been modified.
Components and functions
A transducer collects the TRMS values of current and voltage, as well as the active power, taking into account the shape of the signal. The Human Machine Interface (HMI) provides excellent support for start-up, optimisation and maintenance. With the help of various screens the system is completely transparent. An automatic casting system controls the transformer and the tap-charger in accordance with the melting plane taking into consideration the dynamic influences of time, energy and THD.
Main benefits in constructing electric arc furnaces
