Responding to a resurgence in the steel industry and the need for experts trained in current steelmaking techniques, this volume goes beyond fundamental modeling concepts to address physical and mathematical modeling, steelmaking technology, and the scientific basis of steelmaking. It also provides computational fluid dynamics (CFD) codes and covers FLUENT software. Written for students in materials, metallurgy, and engineering, the text is based on classroom-proven notes that have trained two generations of steelmakers. The author includes a practice session on physical mathematical modeling, complete with review problems. A solutions manual is available for qualifying instructors.
