Mathematical Model for Heat Transfer in Oxygen Steelmaking Process

Steelmaking is energy-intensive with 20-40% of production costs dependent on energy utilization. 70% of global steel production is met by Basic Oxygen Furnace (BOF). Studies have focused on monitoring, controlling and measuring the physiochemical process in BOF, but few discuss heat transfer. Previous studies assume linear or fixed temperature profiles of slag and steel bath. However, temperature is a function of heat content and can fluctuate based on heat generation and absorption, leading to a distinct temperature profile that affects heat transfer. This Ph.D. focuses on understanding the heat transfer aspects in BOF processes.
