Features: This book is divided into five chapters, covering the production and development of ductile iron, the design principles of nodulizing agent composition, the production methods of nodulizing agent, the quality control of nodulizing agent production process, and the evaluation of nodulizing agent quality. The author analyzes and studies the problems that frequently occur in the production application of nodulizing agents from both theoretical and practical perspectives. The focus of the book is on discussing the issues related to the pyrometallurgical melting of nodulizing agents and their quality evaluation standards, including thermodynamic and kinetic factors, with a particular emphasis on kinetic factors that affect the production performance, as well as the impact of production process quality control on nodulizing agent quality. Based on this, the book proposes comprehensive standards for evaluating nodulizing agent quality. It also provides some explanations on other types of nodulizing agents. The book further suggests that producing high-quality nodulizing agents stably over the long term requires not only technology but must also be combined with scientific and strict management. It hopes that both ductile iron production plants and nodulizing agent production plants can achieve a unified understanding of nodulizing agent quality standards, which will help promote the development and application of ductile iron.
