A Blast Furnace is a reactor which is charged continuously and tapped intermittently. But the way technology has improved, bigger and the most modern furnaces are almost tapping continuously. The largest furnaces can tap even 10,000 tonnes of hot metal every day. Tthe solids like coke, sinter, lump ore, pellets, limestone, quartzite and sometimes even BOF slag and Manganese ore are charged into the furnace from the top using a double bell system in the old furnaces and by bell-less charging in all the modern furnaces. As the Raw materials descend from top to bottom, these come into contact with the ascending hot gases from the tuyere zone upwards, as the coke burns in the raceway in a blast furnace. Thus, the heat is transferred from hot gases to the colder raw materials and these get heated up. The volume of the raw materials expands with increasing temperature and the increase in the diameter of Blast furnace proves useful to accommodate this expansion. Once the materials are sufficiently heated up and the Carbon Monoxide and Carbon reduces the iron ore, the charge starts to fuse and form metal and slag and now it contracts in volume. Thus, the diameter of furnace needs to be reduced accordingly.The waste gases are collected at the top and liquids like slag and molten iron at the bottom. The section is reduced at the top since the collection of gases in a vast area is difficult. The strength and quality of the available coke determines the effective height of the furnace.The BF height depends normally on the strength of the coke available in India. After all, the column of charge material is so heavy and it should not pulverise the coke else the permeability or the passing of gases through the descending column would come to a halt. So, normally any increase in the effective volume is achieved through the increase in the cross section of the furnace keeping the furnace height practically the same. Of course, once design phase is over, one cannot change a furnace's dimensions without a complete blow-out.In this book, before detailing the mathematical modelling a few basics of chemistry and metallurgy have been introduced. The fundamentals of Chemistry and Thermodynamics are first covered. There is a need to know about Physical Metallurgy including the very well-known Iron-Carbon Equilibrium process. Next we learn about the Physico-Chemical and the thermal Principles of Blast Furnace Metallurgy. Chapter 4 is the most relevant one and the whole book revolves around it. It is named the Blast Furnace Calculations. After that Mathematical Models have been discussed. Here the emphasis has been given upon the Models as supplied by Rautaruukki OY, Finland to various Steel Plants in India. In another Chapter the RIST Model and C-DRR diagram are specially touched upon.The Blast furnace is a dynamic process and use of computers is a pre-requisite for analysing the Blast Furnace process in real-time. This has also been discussed. Lastly, we discuss about the latest Developments in Blast Furnace Technology, in general.Students studying B. Tech and higher levels may find this book interesting since this book is not written in a very traditional way. It has been the endeavour of Author to keep things simple and understandable. Working engineers may also find it useful.

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.

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.

The Iron Blast Furnace: Theory and Practice presents the significant role of iron blast furnace by which iron is efficiently and rapidly reduced from ore and it is the basis for all primary steelmaking. This book discusses the importance of blast-furnace process as a complete operation. Organized into 14 chapters, this book begins with an overview of the existing experimental, theoretical, and operational evidence about the blast furnace. This text then examines the blast furnace from the outside, including its size, production rate, products, raw materials, operation, and costs. Other chapters consider the primary objective of the blast furnace to produce molten iron of constant composition. This book discusses as well the operation of the furnace from the point of view of what happens to the raw materials after they enter the furnace. The final chapter deals with the linear programming methods by using the known physical constraints on industrial furnaces. This book is a valuable resource for engineers.

Advances in Systems, Computing Sciences and Software Engineering This book includes the proceedings of the International Conference on Systems, Computing Sciences and Software Engineering (SCSS’05). The proceedings are a set of rigorously reviewed world-class manuscripts addressing and detailing state-of-the-art research projects in the areas of computer science, software engineering, computer engineering, systems sciences and engineering, information technology, parallel and distributed computing and web-based programming. SCSS’05 was part of the International Joint Conferences on Computer, Information, and Systems Sciences, and Engineering (CISSE’05) (www. cisse2005. org), the World’s first Engineering/Computing and Systems Research E-Conference. CISSE’05 was the first high-caliber Research Conference in the world to be completely conducted online in real-time via the internet. CISSE’05 received 255 research paper submissions and the final program included 140 accepted papers, from more than 45 countries. The concept and format of CISSE’05 were very exciting and ground-breaking. The PowerPoint presentations, final paper manuscripts and time schedule for live presentations over the web had been available for 3 weeks prior to the start of the conference for all registrants, so they could choose the presentations they want to attend and think about questions that they might want to ask. The live audio presentations were also recorded and were part of the permanent CISSE archive, which also included all power point presentations and papers. SCSS’05 provided a virtual forum for presentation and discussion of the state-of the-art research on Systems, Computing Sciences and Software Engineering.
