| Research Abstract |
In ironmaking process, drastic reduction of carbon dioxide emissions has been urgently required and the positive utilization of lower-grade of raw materials will be next mission since due to the depletion of high-grade resources. The objective of the present study is to search for a new principle of ironmaking process, which can resolve these problems. Ultra-high pressure reduction process under 80 atm using the composite materials of iron ore and carbonaceous materials was focused on. Effect of ore and carbonaceous material property on the reduction behavior was evaluated. Mathematical simulation based on unreacted-cored model was carried out. Further, the optimum structure of the composite and new process principle was proposed.
