A study of kinetics and mechanisms of iron ore reduction in ore/coal composites
Abstract
Blast furnace ironmaking technology, by far the most important ironmaking process, is based on coke and iron ore pellets (or sinter) to produce liquid iron. However, there has been a worldwide effort searching for a more economical and environmental friendly alternative process for the production of liquid iron. The essential requirement is that it should be minimized in the usage of metallurgical coke and agglomerate of iron ore concentrates. With iron ore concentrate and coal as raw materials, there are two approaches: (a) Smelting reduction; melting the ore before reduction; (b) Reduction of the ore in solid state followed by melting. The present work is on the fundamentals of the latter. It consists of a better designed experimental study including pressure gradient measurement, and a more rigorous non-isothermal and non-isobaric mathematical model. Results of this work may be applied to carbothermic processes, such as FASTMET and LB processes, as well as recycling of fines in steel plants.
