if hot metal from a blast furnace or direct-reduced iron is available economically, these can also be used as furnace feed. A typical steelmaking arc furnace is the source of steel for a mini-mill, which may make bars or strip product. Mini-mills can be sited relatively near to the markets for steel products, and the transport requirements are less than for an integrated mill, which would ...

28/10/2014  • The electric arc furnace consists of a circular bath with a movable roof, through which three graphite electrodes can be raised or lowered. • At the start of the process, the electrodes are withdrawn and the roof swung clear. The steel scrap is then charged into the furnace from a large steel basket lowered from an overhead travelling crane. • When charging is complete, the roof is swung back into position and the electrodes lowered into the furnace. • A powerful electric

Electric Arc Furnace Process - an overview ScienceDirect ...

Modern steelmaking is an integrated process consisting of blast furnace (BF) ironmaking and basic oxygen furnace (BOF) or electric arc furnace (EAF) steelmaking. Molten steel from BOF or EAF process can undergo a secondary refining process in a ladle furnace, or be sent directly to the continuous caster. During ironmaking, when smelting ore, iron scrap, coke, and flux, BF slag is formed and subsequently discharged. Steel slag is formed and discharged when smelting iron

Electric Arc Furnace Design Operation and Working ...

The Second World War saw a steep increase in the use of these furnaces leading to the modern Electric Arc Furnace design operation and working principles. These improvements to the processing of scrap steel comprised of larger more efficient and higher capacity furnaces; a 100T furnace would process the scrap in about an hour, using a transformer of 60MVA capacity. High temperatures produced from the arc

Steel - Electric-arc steelmaking Britannica

The furnace. The electric-arc furnace (EAF) is a squat, cylindrical vessel made of heavy steel plates. It has a dish-shaped refractory hearth and three vertical electrodes that reach down through a dome-shaped, removable roof (see figure). The shell diameter of a 10-, 100-, and 300-ton EAF is approximately 2.5, 6, and 9 metres. The shell sits on a hydraulically operated rocker that tilts the furnace forward for

Electric Arc Furnace vs. Blast Furnace Steel Supply, L.P.

11/09/2020  The Electric arc furnace is smaller and more efficient. They do not require a constant coke supply; instead, they use electricity carried through graphite electrodes to create an arc. The metal used with an Electric arc furnace is usually scrap steel. Managing the temperature within the system is easier than a blast furnace, making it more efficient. Another benefit of using the EAF process is that all
