CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

FUNDAMENTALS OF IRON ORE SINTERING R. P. Bhagat INTRODUCTION The process of sinter making originated from a need to make use of fines generated in mines and in ore benefiCiation plants. With the development of sintering technology, a sintering plant has become a tremendous success for providing a phenomenal increase in productivity and saving in coke rate to the blast furnace. The

Numerical Modeling of the Iron Ore Sintering Process

The iron ore sintering process is extremely complicated, involving a large number of inter-related vari-ables. Since the 1950s many studies have been carried out to understand the factors that determine sinter plant perfor-mance usually expressed in terms of productivity, coke requirements and product quality and the effect of raw material properties (viz., iron ore, flux and adjunct

Iron Ore Sinter an overview ScienceDirect Topics

Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics. Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in
