Abstract

The increase in Basic Oxygen Furnace (BOF) plants in steelmaking has given rise to renewed interest in a dynamic simulation of the BOF process. Material and process costs can be saved with optimized process times and targeted charging of scrap and slag formers. Beside hot metal, scrap is the main source of iron in the BOF process. Furthermore, scrap is used as a coolant during the process due to exothermal chemical reactions occurring in the BOF. In this paper, the melting and dissolution behaviour of scrap in the BOF process is discussed. A new dynamic thermodynamic and kinetic Matlab® model used to simulate scrap melting behaviour as a function of various scrap surface parameters and particle size is presented, as well as the influence of scrap properties on liquid bath temperature and final crude steel composition after a defined blowing period.
