Abstract

Knowledge of the constraints imposed on the iron blast furnace by the First and Second Laws of Thermodynamics can be used to formulate a conceptual model of the process. Semiquantitative conclusions can be reached by an analysis of the dictates of the oxygen balance, stoichiometry, and chemical equilibria of the iron oxides and reducing gases, the kinetics of reduction, and coke gasification. These constraints are manifest in the process as a self-regulatory response to changes in control variables. The results of this analysis lend a perspective for understanding the relationships between various operating and process variables and the chemical efficiency and productivity of the process.
