Ebook: Modern Blast Furnace Ironmaking

This book describes the principles of the blast furnace process and especially the control of the process. As a starting point, the blast furnace is seen as a simple iron ore smelter, while gradually the physical, chemical and metallurgical background of the blast furnace process is clarified. The book focuses on the control of the blast furnace 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 optimization of coal injection. The optimization of the blast furnace process is not only based on ‘best practice transfer’, but also requires conceptual understanding as to why a measure works well in some cases and does not work in other situations. In other words: operational improvement is not only based on know–how, but on know–why as well. This publication was and can be used as an introductory text for students of metallurgy as well as for blast furnace operators and management. The latter will benefit to solve operational problems and process optimization issues. The authors have very extensive experience as operators as well as consultants to many steel plants worldwide. With Modern blast furnace ironmaking - An Introduction the reader has a compact compendium of the blast furnace process available: by operators and for operators and for those who are preparing to become operators.
In the second edition of “Modern Blast Furnace Ironmaking”, we have included our insights gained during numerous discussions with colleagues all over the world and our own internal core team. We have also greatly benefited from the many courses and questions raised by the participants in these courses.
The objective of this book is to share our insights that optimization of the blast furnace is not only based on “best practice transfer”, but also requires conceptual understanding why a measure works well in some cases and does not work in other situations. In other words, operational improvement is not only based on know–how, but on know–why as well.
We are indebted to many people we have worked with. We are grateful for the contributions of Renard Chaigneau, Tim Vander and Jennifer Wise, who re–wrote chapters III, IV and X respectively. Ing. Oscar Lingiardi, Prof. Dr. Fernando Tadeu Pereira de Medeiros, Prof. Dr. I. Kurunov and Ing. Vincenzo Dimastromatteo have given us valuable comment and taken care of translations into Spanish, Portuguese, Russian and Italian. A special word of thanks to John Ricketts, who helped develop the material covered in the first edition of this book into a blast furnace operator course, has helped enormously with teaching materials and has shared his insights with us for more than 15 years.
Danieli Corus directors Mr. P. Zonneveld and previously N. Bleijendaal encouraged us to write the first and second edition of this book. We thank Edo Engel at XLmedia for the editing.
We learn by sharing our knowledge. We wish the same to our readers.
