Abstract

The principal objective of this work is to understand the physicochemical behaviour of the ferrous raw material (pellet and/or sinter) bed mixed with nut coke under the blast furnace conditions. To investigate this behaviour, a specially designed blast furnace simulator called the Reduction Softening and Melting (RSM) apparatus is utilised (Chapter 3). In the RSM, blast furnace conditions of gas (varying profile of CO-CO2-H2-N2 gas mixture), load and temperature (20-1550 oC) were simulated for a stationary raw materials bed.
