Modern Blast Furnace Ironmaking: An Introduction (Third Edition, 2015)IOS Press, 7 квіт. 2015 р. - 228 стор. This book describes the blast furnace process for operators. As a starting point, the blast furnace is seen as a simple iron ore melter, while gradually the physical, chemical and metallurgical background is clarified. Operational observations, challenges and remedies are explained from this perspective. Optimization of the blast furnace process is not only based on “best practice transfer”, but also requires conceptual understanding of what works when. In other words: operational improvement is not only based on know–how, but on know–why as well. With Modern Blast Furnace Ironmaking – An Introduction (Third Edition, 2015) 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. |
