Abstract
In a process for the production of steel from scrap in a refining vessel having feed nozzles below the surface of the steel bath and top-blowing devices and in which carbonaceous solid fuel and oxygen-containing gases are used as reagents, the same reagents are used to supply heat to the scrap and to the melt in the refining vessel and the resulting gaseous reaction products are after-burned with preheated air.
