Electric arc furnace An electric furnace that uses the high temperature of an electrode arc to melt ore and metals. When the gas discharge forms an arc, the energy is very concentrated, and the temperature in the arc region is above 3000 ° C. For smelting metals, the electric arc furnace is more flexible than other steelmaking furnaces. It can effectively remove sulfur and phosphorus impurities. The furnace temperature is easy to control and the equipment covers a small area. It is suitable for smelting high-quality alloy steel.
Electric arc furnace Application range:
With the improvement of electric arc furnace equipment and the improvement of smelting technology and the development of the electric power industry, the cost of electric arc furnace steelmaking continues to decline. Now EAF steelmaking is not only used to produce alloy steel, but also used to produce ordinary carbon steel in large quantities The proportion of output in the total steel output of major industrial countries continues to rise
The EAF can not only smelt high-quality steel with low phosphorus, sulfur, and oxygen content, but also alloy with a variety of elements (including lead, boron, vanadium, titanium, and rare earths that are easily oxidized) to produce various high-quality Steel and alloy steel, such as ball bearing steel, stainless acid-resistant steel, tool steel, electrical steel, heat-resistant steel, magnetic materials, and special alloys.
