In the casting field, soaring of fossil fuel cost and destruction of the global environment have become serious issues. We must be replacing coal coke and carburization material with solid bio-fuel that be able to realize environmental protection while accommodating economic growth. This study has purpose for quantitative measurement of the carbon effect in casting process by solid bio-fuel; Biocoke. Our previous studies have found that can make the casting of carburized molten metal by Biocoke's bio-carbon, but the carburizing process has not been clarified. An experimental equipment is using high-frequency induction melting furnace. For quantitative measurement of the carbon effect, contact by surface of Biocoke and melted metal. Especially, carbon effect was suggested with various degrees of carbonized Biocoke. From the results of experimental, it is considered that Biocoke is carburized after being carbonized above the molten metal. Furthermore, it was found that the carburizing effect in the casting process increases in the order of semi-carbonized Biocoke > carbonized Biocoke > Biocoke, and the carbonization property of Biocoke depends on the heat environment temperature and affects the carburizing effect.
