This book analyzes the mechanism of the application of CO2 in steelmaking, by looking at the thermodynamics and kinetics of the reactions of CO2 with the elements present in molten steel. This book is the first academic monograph either at home or abroad on the application of CO2 in the steelmaking field. The thermodynamic conditions of the reactions of CO2 with silicon, manganese, phosphorus, chromium, nickel, vanadium, and other elements were calculated and analyzed using the FactSage thermodynamic software, and the selective oxidation law of the above multiple elements by CO2 was also analyzed. In terms of kinetics, the interfacial reaction mechanism of CO2 was analyzed via gas isotope exchange technology, and the O2 transfer process and transfer rate between the CO2, slag, and steel were studied. In terms of materials and energy balance, how to use the high-temperature characteristics of CO2 to control the temperature of the molten pool, improve the reaction conditions of molten iron, reduce the evaporation of molten iron, and reduce the amount of steelmaking dust were introduced. Based on the experimental data, theoretical models of unit operation for the application of CO2 in steelmaking were established, including decarburization, denitrification, dephosphorization, decarburization and chromium retention, vanadium extraction, and carbon preservation, and these theoretical models were applied to the steelmaking production process, which is an important step in going from theory to practice. The above research work has opened up a new solution for energy saving and liquid steel cleaning in the iron and steel production process and represents progress in steelmaking technology. This book is used as a reference book for managers, engineering and technical personnel, and related professional teachers and students of Iron & Steel enterprises, government departments, consulting services and evaluation agencies, colleges, and secondary professional schools.

This authoritative account covers the entire spectrum from iron ore to finished steel. It begins by tracing the history of iron and steel production, right from the earlier days to today’s world of oxygen steelmaking, electric steelmaking, secondary steelmaking and continuous casting. The physicochemical fundamental concepts of chemical equilibrium, activity-composition relationships, and structure-properties of molten metals are introduced before going into details of transport phenomena, i.e. kinetics, mixing and mass transfer in ironmaking and steelmaking pro-cesses. Particular emphasis is laid on the understanding of the fundamental principles of the processes and their application to the optimisation of actual processes. Modern developments in blast furnaces, including modelling and process control are discussed along with an introduction to the alternative methods of ironmaking. In the area of steelmaking, BOF plant practice including pre-treatment of hot metal, metallurgical features of oxygen steelmaking processes, and their control form part of the book. It also covers basic open hearth, electric arc furnace and stainless steelmaking, before discussing the area of casting of liquid steel—ingot casting, continuous casting and near net shape casting. The book concludes with a chapter on the status of the ironmaking and steelmaking in India. In line with the application of theoretical principles, several worked-out examples dealing with fundamental principles as applied to actual plant situations are presented. The book is primarily intended for undergraduate and postgraduate students of metallurgical engineering. It would also be immensely useful to researchers in the area of iron and steel.
