Outline of Final Research Achievements

The aim of this research is to optimize use of earthquake-induced woody biomass for ironmaking by a new cohesive zone simulator. In order to understand softening and melting behavior of iron burden with woody biomass, carburization reaction by several kinds of woody biomass was investigate using the new cohesive zone simulator. The new simulator can obtain an “in-situ” quenched sample when softening and melting reaction occurs. This kind sample is difficult to get from ordinary cohesive zone simulator. The results from combination of the new cohesive zone simulator and direct measurement apparatuses of laser microscopy and XRD with high temperature furnace were indicated that woody biomass has higher reactivity than ordinary coke because it has lower concentration of ash.
