Nodularization and inoculation are the two necessary processes for the production of ductile iron. Due to the uncertainty of the metallurgical state of the base iron, fixed nodularization and inoculation often lead to "over-nodularization" or "under-nodularization". In order to avoid "over-nodularization" or "under-nodularization", the authors designed and trial-produced a dynamic control system for the nodularization and inoculation. Based on monitoring the main chemical composition, oxygen content, sulfur content and melt temperature and evaluating the nodularized and inoculated performance of the base iron, the addition amount of nodulizer and inoculant can be given. After nodularization and inoculation, the nodularization and inoculation effects are detected by the rapid analysis equipment in front of the furnace, unqualified melts shall be fine-tuned or rehandled. Through the simulation test in the casting production practice workshop of the school, the experimental results preliminarily show that this method can effectively control the nodularization and inoculation process of ductile iron.
