摘要

To extend the scope of fuel types used in iron making process, the possibilities to utilize semi-coke as injected fuel for blast furnace and alternative fuel for sintering were studied comprehensively. Both the basic properties (proximate and ultimate analysis) and technological properties (grindability, explosivity, fluidity, igniting temperature, calorific value, etc.) were analysed and compared with traditional fuels used in the pulverized coal injection and sintering processes. Furthermore, the results of industrial application confirmed the technological and economical advantages to utilize semi-coke in those two processes.
