Title
Study on the Effects of Graphite Spheroidizer in the Spheroidal Graphite Cast Iron
이해창Hae Chang Lee, 김수영Soo Young Kim
Abstract
Most study on fading phenomena in making spheroidal graphite cast iron was on fading only after inoculation. Definite conclusion of variable fading phenomena depending upon additive or inoculant or various components and their relationship one another has not been reached. It is important to investigate the factors of fading phenomena mentioned above, so in this study we tried to investigate some of these factors. When the specimen which was inoculated ten minutes after the addition was compared with the specimen held for ten minutes after the addition only and with the specimen held for tea minutes after the addition immediately followed by inoculation, the specimen inoculates ten minutes after the addition was best in microstructure, tensile strength and hardness.
