Characteristics of Mold Filling in Evaporative Pattern Casting Process

以现代企业资本结构理论为指导，给出了影响资本结构的主要因素。利用综合测试法对某上市公司的资本结构进行了实证分析，为企业的融资决策提供了参考依据。

This paper deals with the flow behavior of melting ZL102 and HT200 in evaporative pattern casting process and discusses the effects of some factors including vacuum degree, pouring temperature, inner gate area, pouring patterns and mold structures upon the filling velocity whereby to find out its laws of mold fillings. The research results can also provide the reliable theory and experimental basis for the proper design of foundry technology of the evaporative pattern casting process and the prevention of defects occured in castings.
