This made it possible to control the power consumption according to the real time and put the power distribution including the alternative production according to the supply plan on a scientific basis and provided a foundation for increasing the production at the UHP electric arc furnace.

The complex introduced a new digital power management apparatus and the principle of sensing earth electric current to monitor the operation of power substations and ensure the balanced supply of electricity. By placing the electrode control system of the UHP electric arc furnace on a CNC basis it has come to ensure the security of electrodes, while remarkably decreasing the norm of electrode consumption, and increase the steel production by cutting down the melting time as compared with that in the past.
