EAF steelmaking technology - what is the future development of it in China

In recent years, the annual output of crude steel in the world has ranged from 1.6 billion tons to 1.8 billion tons, including more than 400 million tons of electric furnace steel, accounting for about 25%. Except for China, the proportion of EAF steel in the global iron and steel industry has reached more than 40%. The proportion of electric furnace steel in the United States has reached 67%, which is the highest proportion of electric furnace steel in developed countries.

Electric arc furnace's introduction

Electric arc furnace​ is an electric furnace for smelting metal and ore at high temperature generated by electrode arc. When gas discharge forms arc, the energy is very concentrated, and the temperature of arc area is above 3000 ℃. For smelting metal, the electric arc furnace has greater process flexibility than other steelmaking furnaces, can effectively remove impurities such as sulfur and phosphorus, the furnace temperature is easy to control, and the equipment covers a small area, which is suitable for smelting high-quality alloy steel.

Electric furnace tapping channel and its function and type

When the electric furnace is tapped, the furnace body is inclined to the tapping direction at a certain angle (usually 45s), and the molten steel flows through the tapping trough and enters the ladle. In addition to diversion of the molten steel, the tapping trough also prevents the molten steel from dispersing and protects the molten steel from secondary oxidation.
