| Research Abstract |
Charcoal use instead of fossil fuel is one of the possible technologies for mitigation of CO2 emission in the steel industry because charcoal can be considered as“carbon-neutral"material. In this study, the possibility of utilization of charcoal as carbon source for carburization reaction was examined ; more specifically effects of carbon crystalinity and ash in charcoal on carbon dissolution into molten iron and iron carburization reaction in iron-charcoal composite were investigated. From these investigations, following results were revealed. Charcoal heat-treated at low temperature, 1273K, has advantage for carbon dissolution reaction into iron bath. Charcoal ash strongly prevents the carburization reaction between iron and carbon.
