With comprehensive energy utilization technology, furnaces of carbon steel lance and furnace door cluster oxygen lance are used for two times burning of CO in molten pool, making full use of chemical energy in flue gas to reduce electricity consumption and build foamed slag and using high impedance technology to raise two When the secondary voltage is increased, the electric power is relatively stable, the impact on the power grid is reduced, the short network system current is smaller, the energy consumption and electrode consumption are reduced, and the effective input of electric power is improved.ġ. Modern steelmaking electric furnace has widely adopted new technologies such as water cooled furnace cover, water cooled furnace wall, conductive lateral arm and eccentric bottom (EBT) tapping. 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.Īccording to the power of the furnace is divided into ordinary power, high power, ultra-high power electric furnace.

When power is fed into the furnace, electricity jumps between the graphite electrodes and they provide the heat needed to melt down steel scrap and iron ore in order to produce crude steel. It uses high voltage electric currents as the primary heat source. The EAF is a cylindrical vessel made of heavy steel plates. While it is possible to produce 100% recycled steel, with a feedstock of only scrap steel, EAF steelmaking often uses a mixture of scrap and DRI, or even supplemental amounts of pig iron (produced in a blast furnace (BF)).
