Electric Arc Furnaces (EAF) | Tenova

An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc, combined with the action of chemical power provided by the use of oxygen and fuel. 

In electric arc furnaces, the charged material is directly exposed to an electric arc, and current from the furnace electrodes passes through the charged material. Arc furnaces differ from induction furnaces, in which the charge is instead heated by eddy currents. 

Technological development has made it possible to increase the use of power, thus increasing the productivity of the melting unit. At the same time, Tenova, with its long experience in the field, has refined the design of the equipment making the EAF extremely efficient and flexible. 

The electric arc furnace is today an equipment capable of melting different charge mixes, from 100% scrap, up to 100% DRI/HBI, passing through all possible combinations between the two extremes, including the use of hot metal.
