method and plant for making steel in a elektrostahlofen equipped with molten pig iron from a minihochofen and less scrap

摘要

In order for the production of steel in the electric steel furnace more independent from the raw material costs, in particular of the scrap prices, to make them as well as to shorten the melting times in the furnace, it is proposed that the electric steel furnace to a maximum of. 70% with scrap (10) as well as to a maximum of. 60% with in a mini high furnace (1) obtained liquid pig iron (7) as well as optionally with further iron carriers (11, 11.1) is provided that the melting process in the electric steel furnace (12) with the use of electrical energy as well as simultaneous use of oxygen and injection coal is operated.
