Fremgangsmåde til smeltning af stål samt indretning til udførelse af fremgangsmåden

摘要

In a process for smelting steel from scrap and/or metal-containing, waste-like materials, the metal carriers (3) are preheated and melted in a fixed bed (1), a slag basicity of between 1.8 and 3, in particular 2 to 2.2, being established. The melt is transferred to a refining vessel (15), and the C content of the melt is increased by adding carbon carriers, in particular by adding carbon or crude iron (4). In an apparatus for carrying out this process, the refining vessel (15) is tightly connected to the smelting reactor (1).
