Theory and Practice of CO2 Utilization in Steelmaking by Rong Zhu Pdf
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.

Ironmaking and Steelmaking by Zushu Li,Claire Davis Pdf
Steel is a critical material in our societies and will remain an important one for a long time into the future. In the last two decades, the world steel industry has gone through drastic changes and this is predicted to continue in the future. The Asian countries (e.g. China, India) have been dominant in the production of steel creating global over-capacity, while the steel industry in the developed countries have made tremendous efforts to reinforce its global leadership in process technology and product development, and remain sustainable and competitive. The global steel industry is also facing various grand challenges in strict environmental regulation, new energy and materials sources, and ever-increasing customer requirements for high quality steel products, which has been addressed accordingly by the global iron and steel community. This Special Issue, “Ironmaking and Steelmaking”, released by the journal Metals, published 33 high quality articles from the international iron and steel community, covering the state-of-the-art of the ironmaking and steelmaking processes. This includes fundamental understanding, experimental investigation, pilot plant trials, industrial applications and big data utilization in the improvement and optimization of existing processes, and research and development in transformative technologies. It is hoped that the creation of this special issue as a scientific platform will help drive the iron and steel community to build a sustainable steel industry.
