In the 80 s, direct current steelmaking electric arc furnaces began to be industrially popularized and applied. In the 90 s, a continuous charging high-temperature preheating direct current electric arc furnace, a double-shell direct current electric arc furnace and a high-impedance alternating current electric arc furnace are developed and popularized in succession. In recent years, various electric furnaces are greatly improved and developed in structure, performance, automation control and processing technology aiming at three major problems of environmental protection, energy conservation and product quality improvement.
