ELECTRIC ARC FURNACES (EAFs)

With state-of-the-art designs and engineering technology, Innov Engineering offers and supplies advanced Electric Arc Furnaces (EAFs) which produce steel, using scrap as raw material. Our EAFs significantly increase productivity by preheating and feeding raw material simultaneously.

The EAFs can produce heat sizes from 3 tons to 200 t, and by utilizing electrical and chemical energy, they can take in raw materials up to 100% scrap and various mixes of hot metal, pig iron, DRI (hot and/or cold), and HBI.

Applications

• All steel scraps
