铸造是国民经济的重要组成产业部门之一,它反映了一个国家制造工业的规模和水平,随着经济建设和市场的需要,对铸件生产实现科学化控制,确保铸件质量,具有极为重要的意义。铸件的质量在很大方面取决于铸件凝固及其相应的充型过程。人们曾用实验法、物理模拟法以及X射线荧光电视及电子扫描等方法和手段,在凝固理论研究方面取得了很大的成就。但是,这些方法也存在着各自的局限性,特别是在考虑各种铸造工艺因素,研究 Casting is one of the important components of the national economy. It reflects the scale and level of manufacturing industry in a country. With economic construction and market demand, it is of great significance to realize scientific control over the production of castings and ensure the quality of castings . The quality of the casting largely depends on the solidification of the casting and its corresponding filling process. People have made great achievements in the study of solidification theory by means of methods of experiment, physical simulation, X-ray fluorescence television and electronic scanning. However, these methods also have their own limitations, especially in considering various casting process factors, research
