Blast furnace phenomena and modelling
Chapter 1 is devoted to the survey of dissected blast furnaces, focusing on their spatial analysis. Chapter 2 deals with the progress made in measuring and control techniques, while Chapter 3 discusses the progress made in constructing mathematical models of the in-furnace state. Chapter 4 deals with the quantification of the flows of gas, liquid and solid materials in the upper and lower parts of the furnace, and related phenomena such as flooding, fluidization, coke movement, raceway behavior, the dead coke zone, and the flow of hot metal and slag at tapping. Simulation test data are also presented. In Chapter 5 the in-furnace high temperature properties of agglomerated iron ores are discussed with regard to establishing important parameters for the construction of mathematical models as well as predicting zone position and level. Chapter 6 deals with the subject of raceway phenomena and tuyere combustion zone models, while Chapter 7 examines slag-metal-gas reaction, with particular emphasis on silicon transfer in the lower part of the furnace. Finally, Chapter 8 presents a number of views regarding future blast furnace technology.
