    and decrease in slag ratio in sinter are effective to improve gas permeability of lower part of blast furnace rather than reducibility of sinter. Due to adoption of these experimental results to a 2-dimentional mathe-matical simulation model, the precision of pressure drop calculation of blast furnace was improved. It is

  • Influence of nut coke on iron ore sinter reducibility ...

    AbstractOne of the most important factors to increase the economic efficiency of the blast furnace process is to reduced coke losses (undersieve product known as nut coke). In recent years there has been increased interest in mixing nut coke in the sinter layers. In order to clarify the influence of nut coke on sinter reducibility, sinter and sinter–nut coke mixtures were isothermally ...

    Jul 15, 2014 · Fine material lowers blast furnace stack permeability, increases dust losses, and may lower the maximum permissible blast temperature for smooth furnace operation. Sinter that is too coarse is also undesirable, particularly if its reducibility is low and it is poor in strength, thus undergoing physical degradation during furnace processing.
