摘　　要：自从1931年Esser和Lautenbusch第一次在铸铁文献中谈及热分析以来,铸铁的热分析技术已经走过了漫长的道路。目前,热分析已被广泛应用于各种铸铁的过程控制。文中综述了热分析在设备和分析方法方面的最新进展,正是这些技术进步使得热分析得以成功应用于评估化学成分、石墨化潜能、石墨形状和数量等。详细分析了热分析技术在预测收缩缺陷倾向方面的潜力和局限性,讨论了预测力学性能和收缩倾向的实例。为了让读者更好地了解各种预测的准确性,文中给出了一些数据和图表。Since its first literature mention in conjunction with cast iron in 1931 by Esser and Lautenbusch,thermal analysis(TA)has journeyed a long way.Today it is an accepted and widely used tool for process control for all types of cast iron.The paper reviews the latest progress in the development of the equipment and analysis methods that makes TA successful in applications such as the estimation of chemical composition,of the graphitization potential,of the shape and number of graphite aggregates.The potential and limitations of prediction of shrinkage defects propensity is analyzed in detail.Examples of attempts at prediction of mechanical properties and shrinkage propensity are also discussed.Several graphs showing the data scattering are presented to convey the reader a better feeling of the accuracy of various predictions.
