Abstract Siemens VAI developed a cyclic calculation which allows on-line description of the complex system, consisting of different charge materials (solid and liquid), steel, slag and offgas during the complete EAF process including tapping. This includes heating, melting and solving of solid materials, chemical reactions and temperature losses. As a result, a full dynamic approach for the mass and heat balance of the EAF heat is created, in accordance to predefined values, so that a complete set of setpoints is obtained.
