Arc Direction Control in DC Electric Arc Furnace

Based on analysis of three dimension layout of power conductors in DC arc furnace, a arc deflection model is established. According to the model, the arc direction of the DC arc furnace can be control-led. The principle and construction of the direction control system are proposed. The results of simulation re-search shows that arc deflection can be quickly corrected and the arc direction can be freely controlled as re-quired.
