CHAPTER-11 FUNDAMENTALS OF IRON ORE SINTERING

influence on the coke rate and blast furnace productivity are (a) reduction properties (RDI/RI) of sinter, (b) Fe content in the sinter, and (c) fines in the sinter. It has been conclusively proved in relation to the blast furnaces (BF) of SAIL- Bhilai,Blast furnace - Wikipedia,Blast furnaces differ from bloomeries and reverberatory furnaces in that in a blast furnace, flue gas is in direct contact with the ore and iron, allowing carbon monoxide to diffuse into the ore and reduce the iron oxide to elemental iron mixed with carbon.MATHEMATICAL MODELLING OF A BLAST FURNACE,Figure 2.
