Carburizing Effect of Cast Iron in High-Frequency Induction Electric Furnace Melting by Bio-Coke

In order to achieve sustainable development goals (SDGs) in the casting process and become a decarbonized society by 2050, decarbonization in the manufacturing process, such as the utilization of converted biomass resources, should be promoted. Recently, using recycled steel scraps that contain small amount of carbon tends to increase as a cheap iron source. In this case, the total amount of carburizer has to increase. Therefore, it is necessary to examine the characteristics of biomass, which is a sustainable carbon source and carbon-neutral, as a substitution for coal coke and to examine the casting method that is friendly to the environment.
