Electric arc furnace is a steelmaking tool with a wide variety of types. Depending on its type, the steelmaking methods may also vary slightly. For example, the operation methods of DC arc furnace and AC arc furnace are different. Let's first talk about the advantages of DC arc furnace!

1. The arc of a DC electric arc furnace is relatively stable and concentrated, the molten pool is well stirred, and the temperature distribution inside the DC electric arc furnace is relatively uniform, with less corrosion to the furnace lining.

2. The current and voltage fluctuations of DC arc furnaces are relatively small, and the impact on the power grid will also be reduced accordingly. The service life of such live cables will be greatly improved.

3. The electrode loss of DC arc furnace is less, and the electrode consumption per ton of steel is half that of AC arc furnace. So it seems that the performance of DC arc furnaces is much better than that of AC arc furnaces.
