Theoretical Investigation on the Blast Furnace Operations with the Aid of Mathematical Model

Abstract

In order to obtain the fundamental informations on the characteristics of blast furnace operations, the longitudinal distributions of process variables, the production rate of pig iron, and the carbon ratio were calculated numerically by the use of a mathematical model involving overall reaction rates of indirect reduction of iron are by CO and H₂, carbon solution, direct reduction of molten wustite by coke, decomposition of limestone, and reaction between coke and steam.
And these calculations were performed with the aid of digital computer under arbitrary data of operating conditions such as top gas pressure, size of charge ore, volume rate of flow of blast, blast temperature, steam ratio and enrichment of oxygen.
