BICを用いた鋳造における加炭プロセスの考察

抄録

Previous studies confirmed that bio-coke effect the carburizing degrees in iron casting by contacting bio-coke with the molten metal. However, the process and mechanism that explain the role of bio-coke in molten metal carbonization have not been clarified. Therefore, this study assumes that carbonized bio-coke came into contact with the molten metal during the casting process, then the molten metal absorbs the carbon from the contacted bio-coke.

Bio-coke samples were thermal-treated at the different carbonization levels. After that, the thermal-treated bio-coke were brought into contact with the molten metal to measure the degree of steel carbonization. The results revealed that the amount of carbon is increased when thermal-treated bio-coke were in touch with the molten metal. Moreover, the degrees of steel carbonization using thermal-treated bio-coke as an agent have been clarified.
