    Abstract

    Fading in ductile iron production covers the loss of inoculation and nodulation effectiveness. The main factors of fading are process time and temperature including rest time between tapping and pouring. This research conducted to see the effect of time rest between tapping and pouring process to the completion of inoculation and nodulation process. Analysis was done on 1 mm plates of TWDI casting process. The liquid metal came from 1 bath. Variations of casting condition were presented. The Tapping temperature was 1550OC. The pouring temperature varied of the first bath was 1399OC, 1389OC, 1385OC and 1381OC. Rest time was analysis as the temperature differences between tapping temperature and pouring temperature. The completion of inoculation and nodulation process were seen in nodule count and nodularity. The result shows that longer rest time lay between tapping and pouring will cause disturbance to inoculation and nodulation process. Apart from that the level of tapping temperature which is also inoculation temperature should be maintained.
