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 Sponge Iron Production in Rotary Kiln written by Arabinda Sarangi and published by PHI Learning Pvt. Ltd.. This book was released on 2011-06-30 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Comprehensively deals with the production of sponge iron in the rotary kiln. It is divided into 17 chapters. The initial chapters give a brief on the fundamental theories and basic principles of sponge iron production, commercially used DR (direct reduction) processes and physico-chemical principles of sponge iron production. The book then goes on elucidating the testing procedures of raw materials needed for the direct reduction processes.

Download or read book ALTERNATIVE ROUTES TO IRON MAKING 2nd Ed written by SARANGI, ARABINDA and published by PHI Learning Pvt. Ltd.. This book was released on 2016 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: With a boom in the steel industry all over the world today, the demand of sponge iron has considerably increased as a feed (raw) material to steel making. The increase in the demand of sponge iron is also due to the fact that it is used for replacing coke making required for blast furnace processing. The primary objective of this book is to provide the basis, principles, fundamentals and theory of sponge iron production. This book, earlier titled as Sponge Iron Production in Rotary Kiln, is revised as per the feedback from students, faculty members and professionals. It, now, covers broad spectrum of alternative routes of iron making, therefore, the book is renamed as Alternative Routes to Iron Making. In this revised edition of the book, three new chapters have been added to fulfil the requirement of a textbook for various universities. NEW TO THIS EDITION • New chapters on: o Utilization of Sponge Iron o Environmental Pollution and Control in Sponge Iron Industries o Smelting Reduction Process • Inclusion of principle of fluidisation in fluidised bed processes • Description of Hyl III process with recent development of the process Primarily intended for undergraduate and postgraduate students of metal-lurgical engineering, this book is equally beneficial for researchers, and professionals engaged in DR processes and steel industries.

Download or read book The Reduction of Iron Ores written by Ludwig von Bogdandy and published by Springer. This book was released on 1971 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the English edition the book was revised by the authors, taking into account a number of suggestions of the readers of the German edition. Some of the most important publications in the field of iron ore reduction, which appeared since 1967, have been used to bring the manuscript as far as possible up to date. The kind assistance of Dr. K. BOHNENKAMP of the Max-Planck-Institut fUr Eisenforschung, Dusseldorf, was much appreciated in this respect. Ohapters 2.9 and 2.10, dealing with the reduction of molten oxide slags by solid carbon and with the contribution of the water-gas reaction to iron ore reduction, have been added for the English edition. Ohapter 2.9 has been completely revised with the kind assistance of Dr. H. J. GRABKE, Stuttgart. Dipl.-Ing. J. LODDE contributed to this edition by revising the bibliography. Owing to the rapid development of the blast furnace it was necessary to revise Ohapter 5 considerably. In this field many valuable suggestions have been made by Dipl.-Ing. G. LANGE and Dipl.-Ing. P. HEINRICH. Furthermore, Ohapters3 and 4 have been thoroughly revised by Dr.-Ing. E. FORSTER and Dr.-Ing. U. SCHIERLOH. Last, but not least, we have to thank our translators for their excellent work.
