热分析法是测试铁水成分的重要方法之一,然而在预测铁水的结晶形态方面却进展缓慢。如用其预测球铁铸件的球化率,国内外都进行了大量研究,但据“AFS Trans”发表的报告,其可靠性只有约80%,这对工业生产来说是不能满足要求的。究其原因,有 Thermal analysis is one of the important methods to test the hot metal’s composition. However, it has been slow to predict the hot metal’s crystal morphology. If it is used to predict the spheroidization rate of ductile iron castings, a great deal of research has been done both at home and abroad. However, according to the report published by AFS Trans, the reliability is only about 80%, which can not meet the requirements for industrial production. The reason, there
