Not quite fifteen years old at the time of the German invasion of Poland in 1939, George Topas was fated to witness the ugliness and brutality of the Nazi reign of terror in his native land--and to survive to tell his story in this compelling book.
The Iron Blast Furnace: Theory and Practice presents theoretical, experimental, and operational evidence about the iron blast furnace as well as a mathematical description of its operation. This book includes a set of equations that accurately describe stoichiometric and enthalpy balances for the process and which are consistent with observed temperatures and compositions in the furnace stack. These equations, which have been devised on the basis of the Rist approach, show the effects of altering any blast-furnace variable on the other operating requirements of the process. This monograph is comprised of 14 chapters and begins with a brief description of the blast-furnace process. The next chapter takes a look inside the furnace, paying particular attention to its behavior in front of the tuyères and the kinetics of the coke gasification reaction. The reader is then introduced to the thermodynamics and stoichiometry of the blast-furnace process; enthalpy balance for the bottom segment of the furnace; the effects of tuyères injectants on blast-furnace operations; and blast-furnace optimization by linear programming. A number of important variables covered by the equations are discussed, including hydrocarbon injection at the tuyères, oxygen enrichment of the blast, moisture, limestone decomposition, coke reactivity, and metalloid reduction. The effects of many of these variables are illustrated numerically in the text while others are demonstrated in sets of problems that follow each chapter. This text will be a valuable resource for metallurgists and materials scientists.
Most people know of the rich Civil War history of the Shenandoah Valley of Virginia but few know that the Valley was also rich in iron smelting history. The first furnace west of the Blue Ridge Mountains was built in this region. For over 144 years the area produced iron ore and smelted ore into pig iron. The region's iron history covered the eras of the bloomery forge, charcoal cold-blast furnace and finally hot-blast coke furnace. "Shenandoah Iron" includes the transporting, mining and smelting activities of this industrial enterprise and explains in detail how iron ore is transformed into iron. Over 24 cold-blast furnaces are described and the two modern hot-blast furnaces are depicted. Over 80 iron mines are identified. The contributions of German-Americans who settled the valley and dominated the iron business are highlighted. The practice of industrial slavery and the impact of the Civil War on the iron industry are explored. This 350 page book includes 137 photographs, maps and drawings to illustrate the contributions that the Shenandoah counties of Clarke, Frederick, Page, Rockingham, Shenandoah and Warren made to the iron smelting industry of the Shenandoah Valley of Virginia.
Modern Blast Furnace Ironmaking – An Introduction (Fourth Edition, 2020) describes the principles of the blast furnace process. As a starting point, the blast furnace is seen as a simple iron ore melter, while gradually the physical, chemical and metallurgical background of the blast furnace process is clarified. The book focuses on the control of the process with respect to thermal control, gas flow control and casthouse operation. In this book, all essential process details are described and a special focus is on cost optimization by low coke rates and on management of the process in case of disturbances and upsets. The optimization of the blast furnace is not only based on “best practice transfer”, but also requires conceptual understanding why a measure works in some cases and not in other cases. In other words, operational improvement is not only based on know–how, but as well on know–why. This publication can be used as an introductory text for students of metallurgy as well as for blast furnace operators and management.
