In the mid-1980s, foreign countries developed direct current arc furnace steelmaking technology. Compared with the exchange of electric arc furnace steelmaking technology, this technology does have many advantages. What are the specific ones? We can followElectric arc furnace manufacturerLet's take a look together!!

1) Reduce electrode consumption by more than 50%; 2) Reduce energy consumption per ton of steel by 5% to 10%;

3) The service life of the furnace lining is extended by more than 30%;

4) The temperature of the molten pool is uniform, and the fluctuation of the tapping temperature is small;

5) Noise reduction of about 10 decibels;

6) Reduce flicker by 50%, with minimal interference to the grid voltage. When using an AC arc furnace, the grid capacity is 1/2, which can meet the requirements. From a structural perspective, the main difference between a DC arc furnace and an AC arc furnace is the addition of a rectifier device that converts AC to DC; The number of graphite electrodes on the furnace top has been reduced from three to one, and a bottom electrode has been added to the furnace bottom. From the perspective of investment efficiency, although the infrastructure investment of DC arc furnaces is about 20% higher than that of AC arc furnaces, the payback period is greatly shortened. If China transforms the old equipment of the original AC electric arc furnace into a DC electric arc furnace, the cost will be recovered in about six months. Alright, the above is an introduction to the advantages of DC arc furnaces. For more details, please follow the official website:=“ http://www.ayynd.com/ " target="_self"> http://www.ayynd.com/
