CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

2012-8-16  It has been conclusively proved in relation to the blast furnaces (BF) of SAIL- Bhilai, TATA STEEL, Schwelgerm and Ruhort (No.6) that Coke rate and productivity are greatly influenced by RI and RDI values of sinter. Understandably, the fines generated inside the furnace during reduction affect the permeability of the stack zone, increase the pressure drop and disturb the gas distribution causing channelling of he furnace.
