The electrosteel furnace (12) is charged up to 70 % with scrap (10), up to 60 % with liquid pig iron produced in a mini blast furnace (1), as well as by choice with further iron-bearing materials (11, 11.1). The mini blast furnace is operated with iron pellets (2) and/or lump ore (3) and coke (4) as well as blown coal (6). The melting process in the electrosteel furnace takes place with simultaneous supply of electric energy, oxygen and blown coal. |
