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…mehr

Produktbeschreibung
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 ofmolten 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 teachersand students of Iron & Steel enterprises, government departments, consulting services and evaluation agencies, colleges, and secondary professional schools.
