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
Blast Furnace Ironmaking: Analysis, Control, and Optimization uses a fundamental first principles approach to prepare a blast furnace mass and energy balance in ExcelTM. Robust descriptions of the main equipment and systems, process technologies, and best practices used in a modern blast furnace plant are detailed. Optimization tools are provided to help the reader find the best blast furnace fuel mix and related costs, maximize output, or evaluate other operational strategies using the ExcelTM model that the reader will develop. The first principles blast furnace ExcelTM model allows for more comprehensive process assessments than the 'rules of thumb' currently used by the industry. This book is suitable for undergraduate and postgraduate science and engineering students in the fields of chemical, mechanical, metallurgical and materials engineering. Additionally, steel company engineers, process technologists, and management will find this book useful with its fundamental approach, best practices description, and perspective on the future. Provides sample problems, answers and assignments for each chapter Explores how to optimize the blast furnace operation while maintaining required temperatures and gas flowrates Describes all major blast furnace equipment and best practices Features blast furnace operating data from five continents

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 objectives of the research consist of developing and applying techniques and model tools allowing an online evaluation of the blast furnace hearth conditions and mainly its permeability, in order to guarantee a stable furnace operation and to control the refractory wear through early corrective actions. CRM determined the coke bed voidage in the hearth of BFB of Cockerill-Sambre by two techniques: one based on pressure measurement inside the taphole and the other based on electromotive force measurement. To get a better understanding of the data, a mathematical model was developed taking into account the movements of the deadman. ln order to continuously determine the hot metal flow rate, BFI measured the filling level in the runner at BF 2 of TKS. A statistical wear model evaluated the cross-sectional runner geometry. The data have been fed into a model to calculate the coke bed voidage on multiple taphole blast furnaces. To control the wear caused by preferential liquid flow, Corus IJmuiden developed a monitoring of temperature and heat flux information from purpose-installed duplex thermocouples. This information has been correlated over time to identify any persistent trends and used to evaluate control measures such as blocked tuyères and process shutdowns. Industrial trials at Fos BF1, consisting of temperature profile measurements along the tuyère axis, radioactive tracer experiments and coke core borings, enabled IRSID to propose a picture for the description of the effects of the central coke charging practice. Moreover, IRSID used the Fluent code ta describe the liquid flow in the hearth with regard to the deadman conditions and to simulate tracer experiments. From studies of the behaviour of the hearth skull, Corus UK proposed a method for its monitoring. The iron flow rate was measured by using strain gauges attached to the torpedo ladles, and the slag flow rate was estimated from the slag pelletiser current. Data from tuyère core drilling samples were examined to estimate the voidage in the hearth.
