10-50t Electric Arc Furnace Steel Smelting
Steelmaking process using electricity as energy source.
The types of steelmaking furnaces are electric arc furnace, induction furnace, electroslag furnace, electron beam furnace, self-consuming electric arc furnace, etc. Usually, the electric furnace steel is produced by alkaline electric arc furnace.

Electric furnace steels are mostly used to produce high quality carbon structural steels, tool steels and alloy steels. This kind of steel has excellent quality and uniform properties. At the same carbon content, the strength and plasticity of EAF steel are better than that of open-hearth steel. The main raw material of EAF steel is similar scrap steel, and sponge iron is also used to replace some scrap steel. The chemical composition and alloy element content are adjusted by adding ferroalloys.
Electric furnace steelmaking with scrap as raw material has less capital investment than that of converter process. At the same time, the development of direct reduction provides metallized pellets to replace most scrap steel for electric furnace, which greatly promotes electric furnace steelmaking. There are about 1400 large electric furnaces in the world. The electric furnaces are developing towards large-scale, ultra-high power and computer automatic control. The maximum capacity of electric furnaces is 400 tons.
EAF arc for a heat source to scrap as raw material for steel smelting general, high-quality carbon steel, alloy steel of various equipment for smelting. Its structure for the furnace cover Rotary Open Top feeding, torque motor electrodes automatic adjustment movements, large cross-section of water-cooled cables, furnace and the furnace cover upgrading Tilting rotation using hydraulic, electrical control by PLC control, technology Advanced.
Steelmaking electric arc furnace is divided into normal power, high power and ultra high power according to matched power. It also can be divided into independent foundation, conjoined foundation, large pivotal bearing and four connecting link structure by roof rotating mechanism. There are left operation and right operation types for user’s selection. According to the loading method, it can be divided into horizontal continuous feeding type electric arc furnace and furnace lid rotating top-opening feeding type electric arc furnace. The electric arc furnace consists of furnace body, furnace roof, tilting device, furnace lifting and rotating device, electrode lifting device, water-cooling device, hydraulic device, furnace transformer, secondary busbar, HV cabinet, LV electric and automatic control system etc.
Function
1. Used for scrap melting, decarbonization, dephosphorization, desulfuration, deoxygenation and molten steel heating, etc. For melting steel of different grades and components.
2. Partial hot metal charging or charging pig iron, sponge iron(DRI) and hot briquetted iron(HBI).
3. Additional charging during the melting process and primary alloying process.
Characteristics
1. Refractory material saving due to the water cooled roof and water cooled panels.
2. Slagless tapping and tapping temperature reducing result from EBT.
3. Dependence of large current reducing due to the copper and steel composited conductive arm and large section water cooled cable.
4. Power consumption for per ton of steel and smelting period are reduced due to adopting furnace door C-O lance and furnace wall coherent oxygen lance.
5. Furnace collection rate is increased due to adopting furnace roof fourth hole and other fume discharging methods.
6. Scrap steel continuous charging and preheating system could be applied thus save energy, reduce consumption and improve smelting efficiency.
7. Raw material(DRI, HBI), lime and alloy automatic charging system could be equipped.
8. Equipped with advanced PLC control system and smelting model.
