Abstract:Iron and steel industry is the basic industry of China's economic development, the future demand for iron and steel in China will remain strong, and the iron and steel industry is also facing huge pressure of carbon emission reduction while developing at high speed. Compared with the long process of converter steelmaking, the short process of electric arc furnace steelmaking has obvious advantages in terms of short process, low energy consumption and low carbon emission. In order to better support the structural adjustment of the iron and steel industry, it is necessary to investigate and understand the technical equipment level and production operation level of electric arc furnace steelmaking. Through investigation, it is found that the nominal capacity of electric arc furnace steelmaking equipment in China is mainly 70-100 t, and the level of technology and equipment is comparable to that of foreign countries. The main electric arc furnace steelmaking production furnaces are running in China, and the level of production and operation can reach the same advanced level in the world. The best smelting cycle level can reach 35 min from tapping to tapping, but the actual operation level of most enterprises is medium, which needs to be further improved. The research results are of great significance for China to achieve the goals of "carbon peak" and "carbon neutrality" and improve the competitiveness of steel supply.
