One of the main charging materials of the basic oxygen furnace process (BOF) is scrap. Scrap acts as a coolant for the exothermic reactions inside the BOF and as an iron source beside hot metal.
A dynamic simulation of the dissolution and melting behaviour of scraps deals with complex physical and chemical phenomena. Due to exact modelling of the BOF process an optimization of tap to tap time followed by reduced operation costs might be possible. Based on a model for BOF converter, coded on MatLab®, several scrap types where investigated. A thermodynamic and kinetic background describes the behaviour of the metal and slag phase during the blowing period of the BOF. This paper should show the behaviour of scrap composition on the final crude steel composition after a defined blowing period. Furthermore, the influence on the final temperature and slag composition will be shown.
