Shifting the limits of nut coke use in the ironmaking blast furnace: A fundamental study on the behaviour of ferrous raw material bed mixed with nut coke

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 ...

Ferrous burden behaviour under nut coke mixed charge conditions

Effect of nut coke addition with ferrous burden (pellet and sinter mixture) is experimentally investigated under simulated blast furnace conditions. Nut coke mixing degree was varied (0, 20 and 40 wt-%) as a replacement of the regular coke. During smelting, the ferrous bed evolves through three distinct stages of shrinkage due to indirect...

A comparative study of pellets, sinter and mixed ferrous burden behaviour under simulated blast furnace conditions

Physicochemical behaviour of the pellets, sinters and its mixture (60% pellets: 40% sinter) is investigated by a series of smelting and quenching experiments. For all ferrous raw-material beds, three distinct stages of bed shrinkage occur due to indirect reduction, softening and melting. However, the characteristic nature (displacement,...
