Tenova was awarded a contract from Tosyali for the supply of an electric-arc furnace (EAF) for its plant in Bethioua, Algeria. This will be the second EAF that Tenova has supplied to this site and is a key component of Tosyali’s current expansion project. The new EAF will be designed to be almost identical to the current EAF, which was supplied in 2016. It will process 2.5 million tons of DRI pellets per year to produce hot-rolled coil (HRC). A charging system will allow charging and melting of more than 12 tons of HDRI (hot DRI) per minute. The composition of the DRI produced and processed at the Bethioua site is adjusted by blending iron concentrates from different sources to achieve the most profitable balance between cost of raw materials and energy.
An advanced EAF process control system compensates for variations of the raw materials and optimizes the process to reach the optimal yield and consumption figures. The new EAF will be powered by a 240-MVA AC transformer.
