Blast Furnace Ironmaking: Analysis, Control and Optimization

Blast Furnace Ironmaking: Analysis, Control and Optimization replaces the 'rules of thumb' currently used by the industry. It shows the beneficial effects of injecting oxygen into the furnace while avoiding the hazards of overheating, the beneficial effects of electrically super-heated blast furnace air blast, and how to obtain the exact hearth and top temperatures that the furnace needs for optimum performance. Users will find an outline on the production of molten iron from ore using the blast furnace process, along with instructions for optimizing the process, including energy and carbon footprint minimization that emphasizes the environment, safety and future developments. This book is suitable for undergraduate and postgraduate science and engineering students and those working in chemical and metallurgical engineering. Additionally, steel company management will find this book useful with its look towards the future. Delivers an a priori technique for calculating blast furnace fuel and oxygen requirementsProvides sample problems and problem assignments at the end of each chapter with answers includedIncludes information on how to optimize blast furnace operations while maintaining required temperatures and gas flowratesFeatures blast furnace operating data from five continents INDICE: 1.
