What is a DC Electric Arc Furnace?
DC electric arc furnace is a steel-making equipment that uses DC power as energy source. Unlike conventional AC arc furnaces, which have been widely used for decades, DC arc furnaces use direct current (DC) as their power source. The transition from alternating current (AC) to direct current has significantly improved energy efficiency, operational flexibility and environmental sustainability. Characteristics of DC Electric Arc Furnace 1. The smelting furnace arc is stable and concentrated, which makes the molten pool well stirred and the temperature in the furnace evenly distributed, thereby reducing the erosion of the furnace lining. 2. Lower energy consumption: Due to good arc stability and small current and voltage fluctuations, the impact on the power grid is also reduced accordingly, which helps extend cable life and improve energy efficiency. At the same time, the electrode consumption of DC electric arc furnaces is also significantly reduced. The electrode consumption per ton o...
