Book Description
This book presents the results of extensive research on the mathematical modelling of the blast furnace process. It describes the mathematical models utilised, providing insights into two-dimensional models of gas dynamics, heat transfer and reduction, the cohesion zone, and the balance equilibrium model. On the basis of these models, it details a method for the analytical study of the blast-furnace process, which essentially complements the experimental methods used in practice. Examples of the solution of practical problems of blast furnace smelting are also provided, and the mathematical models highlighted here can be used in research and design institutes, at metallurgical enterprises and for higher education institutions in the training of students in metallurgical specialties.

Book Description
The Special Issue presents almost 40 papers on recent research in modeling of pyrometallurgical systems, including physical models, first-principles models, detailed CFD and DEM models as well as statistical models or models based on machine learning. The models cover the whole production chain from raw materials processing through the reduction and conversion unit processes to ladle treatment, casting, and rolling. The papers illustrate how models can be used for shedding light on complex and inaccessible processes characterized by high temperatures and hostile environment, in order to improve process performance, product quality, or yield and to reduce the requirements of virgin raw materials and to suppress harmful emissions.

Book Description
As ironmakers are well aware, it was only a few decades ago that the blast furnace was viewed as a strange 'black box'. Recently, however, various in-furnace phenomena have become the subject of serious scientific study, largely as the result of the 'dissection' of dead furnaces, together with the development of advanced monitoring and control techniques. In this way, a new frontier has been opened within the venerable domain of metallurgy. In the light of these new developments, the Committee on Reaction within Blast Furnaces was set up in March 1977 by the Joint Society ofIron and Steel Basic Research - a cooperative research organization of the Iron and Steel Institute of Japan (ISIJ), the Japan Institute of Metals (JIM) and the Japan Society for the Promotion of Science (JSPS). Consisting of twenty-six members and advisors drawn from the fields of academia and industry, this committee collected, discussed, and evaluated numerous papers during its five year commission. Particular attention was paid to the interpretation of findings drawn from the autopsy of dead furnaces, in the context of the live furnace state, and the correlation of data regarding cohesive zone configuration, level, and furnace performance. The results of this intense research activity are presented here in the hope that they will serve not only as a source of enrichment to the professional knowledge of researchers and operators, but also as textual material for graduate students in the field of metallurgy.

Book Description
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.

Book Description
This authoritative account covers the entire spectrum from iron ore to finished steel. It begins by tracing the history of iron and steel production, right from the earlier days to today’s world of oxygen steelmaking, electric steelmaking, secondary steelmaking and continuous casting. The physicochemical fundamental concepts of chemical equilibrium, activity-composition relationships, and structure-properties of molten metals are introduced before going into details of transport phenomena, i.e. kinetics, mixing and mass transfer in ironmaking and steelmaking pro-cesses. Particular emphasis is laid on the understanding of the fundamental principles of the processes and their application to the optimisation of actual processes. Modern developments in blast furnaces, including modelling and process control are discussed along with an introduction to the alternative methods of ironmaking. In the area of steelmaking, BOF plant practice including pre-treatment of hot metal, metallurgical features of oxygen steelmaking processes, and their control form part of the book. It also covers basic open hearth, electric arc furnace and stainless steelmaking, before discussing the area of casting of liquid steel—ingot casting, continuous casting and near net shape casting. The book concludes with a chapter on the status of the ironmaking and steelmaking in India. In line with the application of theoretical principles, several worked-out examples dealing with fundamental principles as applied to actual plant situations are presented. The book is primarily intended for undergraduate and postgraduate students of metallurgical engineering. It would also be immensely useful to researchers in the area of iron and steel.

Book Description
This publication reports the proceedings of a one-day seminar on The AppZicatian af Mathematics in Industry held at the Australian National University on Wednesday, December 3, 1980. It was organized jointly by the Division of Mathematics and Statistics, CSIRO, and the Departments of Pure and Applied Mathematics, The Faculty of Science, Australian National University. A paper based on the talk "Some uses of statistically designed experiments in industrial problems" given by N.B. Carter at the Seminar was not received by the editors. Though R.M. Lewis of John Lysaght (Australia) Limited did not present a talk, the editors invited him to submit a paper. They only learnt about his work after the program for the seminar had been finalized and publicized. His paper appears as the last paper in these proceedings and is entitled "A simple model for coil interior temperature prediction during batch annealing". The seminar was opened by Dr J.R. Philip, FAA, FRS, Director of the Physical Sciences Institute, CSIRO. He kindly agreed to supply an edited version of his comments for inclusion in the proceedings. They follow the Foreword as Opening Remarks.
