Modeling of Steelmaking Processes
Preview
Book Description
From the prediction of complex weather patterns to the design of swimsuits, modeling has, over the years, quietly but steadily become an essential part of almost every field and industry—and steelmaking is no exception. Factors such as visual opacity, high operating temperature, and the relatively large size of industrial reactors often preclude direct experimental observation in steel manufacturing. Therefore the industry is overwhelmingly dependent on modeling to quickly and cost-effectively provide insight into analysis, design, optimization, and control of processing. However, few, if any, books offer the adequate coverage of modeling.
Addresses Fundamental Principles of Physical and Mathematical Modeling in Steelmaking Processes
Modeling of Steelmaking Processes meets that ever-present demand and provides a solid knowledge base on which to build. With content designed to serve professionals and students, this book starts with an overview of steelmaking and develops into a focused description of underlying scientific fundamentals and applications.
This powerful learning tool:
- Presents an overview of steelmaking, the relevance of modeling and measurements, the evolution of steelmaking, and modern technology
- Discusses emerging issues, such as environmental emissions, recycling, and product development and quality
- Reviews computational fluid dynamics (CFD) software
- Analyzes mechanistic, AI-based, and macroscopic models, to provide a holistic view of steelmaking process modeling
- Provides useful questions and problems, as well as a practice session on modeling, to reinforce understanding
Developed as a self-tutorial, this text explores thermodynamic principles, analysis of metallurgical kinetics and transport phenomena, and key numerical methods, helping readers easily navigate a generally complex subject.
