Analysis on key points of cost decreasing and efficiency increasing of electric arc furnace steelmaking in China

The output of the electric arc furnace steelmaking was discussed, as well as the equipment and the main consumption index. Some characteristics were summarized, including that the electric arc furnace steelmaking ratio of China was lower than the world average level, the electric arc furnace has made much progress in becoming large sized, and the decreasing tendency about the unit scrap consumption of electric arc furnace was reversed. And, the key points of cost decreasing and efficiency increasing of the electric arc furnace steelmaking were put forward on multi dimension, namely electricity price reform, optimization of the furnace burden structure, furnace type selection, energy saving process, greenization and intellectualization, management innovation, standardization system construction and so on. Meanwhile, the viewpoint that the electric arc furnace steelmaking was facing development opportunities was put forward, and increasing investment in technology R&D and application continuously and working together to realize the sustainable development of the electric furnace steelmaking were proposed.
