Download or read book Hot Metal Production by Smelting Reduction of Iron Oxide written by AMIT CHATTERJEE and published by PHI Learning Pvt. Ltd.. This book was released on 2014-04-03 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, in its second edition, continues to offer a comprehensive treatise on smelting reduction of iron oxide—an emerging alternative method of producing hot metal without using coke. This technique is being increasingly used for hot metal production, which has till date, been dominated by the traditional blast furnace method. Shortage of coking coal, high cost of coke and the recent enforcement of stricter environmental regulations have resulted in the advent of smelting reduction as a supplementary method of hot metal production. The book covers the details of this rapidly emerging method that holds particular relevance for countries like India, endowed with relatively large reserves of high grade iron ore but unfortunately, not matched by the availability of coking coal. The book offers an in-depth analysis of the theoretical as well as the practical aspects of smelting reduction. It begins by acquainting the readers with the current worldwide status of ironmaking, followed by the classification of the various smelting reduction processes. It then focuses on explaining the fundamentals of smelting reduction before proceeding with a critical appraisal of the various smelting reduction processes that are currently available. The future of this methodology in India and in the rest of the world is discussed in the concluding chapter. The book contains numerous illustrations to provide a clear understanding of the different processes, equipment and quality parameters relevant to smelting reduction-based ironmaking. The book is intended mainly for undergraduate and postgraduate engineering (particularly metallurgical engineering) students seeking an insight into this emerging ironmaking technology. It would also be of immense interest to researchers and technologists engaged in the subject of smelting reduction of iron oxide. A variety of chapter-end references would enable teachers and students to get acquainted with the extensive knowledge already available in this field. HIGHLIGHTS OF SECOND EDITION • Two new sections on HIsarna process and Circosmelt process have been incorporated. • New figures and tables have been used in some sections to illustrate the concepts with better clarity and give the up-to-date information. • Some references have also been added, making the text suitable for further study.

Download or read book SPONGE IRON PRODUCTION BY DIRECT REDUCTION OF IRON OXIDE written by AMIT CHATTERJEE and published by PHI Learning Pvt. Ltd.. This book was released on 2012-09-12 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a fascinating study of the very important emerging field of direct reduction in which iron ore is ‘directly reduced’ in the solid-state, using either natural gas or non-coking coal, to produce a highly metallised material, referred to as sponge iron (or direct reduced iron). This intermediate product is subsequently melted in electric arc furnaces or induction furnaces (sometimes even in basic oxygen furnaces) to produce liquid steel. Such a process combination enables steel to be produced without using coking coal, which is an expensive input in the normal blast furnace—basic oxygen furnace route of steelmaking adopted in integrated steel plants. The book offers comprehensive coverage and critical assessment of various coal-based and gas-based direct reduction processes. Besides dealing with the application of the theoretical principles involved in the thermodynamics and kinetics of direct reduction, the book also contains some worked-out examples on sponge iron production. The concluding part of this seminal book summarises the present and future scenario of direct reduction, including the use of gas generated from coal in direct reduction processes. The book is primarily intended for the undergraduate and postgraduate students of metallurgical engineering. It is also a must-read for researchers, technologists and process metallurgists engaged in the rapidly developing field of direct reduction of iron oxides, which is of critical importance for India and other developing nations that are beginning to play a major role in global steelmaking.

Download or read book Modern Blast Furnace Ironmaking written by M. Geerdes and published by IOS Press. This book was released on 2015-04-07 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the blast furnace process for operators. As a starting point, the blast furnace is seen as a simple iron ore melter, while gradually the physical, chemical and metallurgical background is clarified. Operational observations, challenges and remedies are explained from this perspective. Optimization of the blast furnace process is not only based on “best practice transfer”, but also requires conceptual understanding of what works when. In other words: operational improvement is not only based on know–how, but on know–why as well. With Modern Blast Furnace Ironmaking – An Introduction (Third Edition, 2015) the reader has a compact compendium of the blast furnace process available: by operators and for operators and for those who are preparing to become operators.
