| Outline of Final Research Achievements |
For realization of fast ironmaking at lower temperature, a possibility of new pretreatment process of raw material for ironmaking using biomass and iron ore was discussed, which was the proportion of the process to prepare FexO and biomass char simultaneously and the examination of reactivity of composite using FexO and biomass char. Laboratory scale experimental apparatus which was simulated the suggested process was fabricated, and the production of FexO from iron ore was carried out. FexO can be produced to optimize the treatment time at 900ºC. This new raw material for ironmaking has higher reactivity than conventional one. However, sulfur in raw material leads to lowering the reactivity. Therefore, the control of sulfur content is very important.
