铸件补缩系统特性的研究郑州电机电器厂崔式荣河南轻工科研所冻慧安一、前言体收缩对铸件的明显影响随凝固条件而异。当凝固过程中固态相分明，如在纯金属或凝固范围窄的合金中可发生的那样，体收缩很容易由系统内自由液面的降低供应由外部的补缩冒口来维持，可以设置补缩...
Research on the Characteristics of Casting Replenishment System Zhengzhou Electrical and Mechanical Appliance Factory Cui Shirong Henan Institute of Light Industry Frozen Hui’an I. Preface The obvious influence of body shrinkage on castings varies with solidification conditions. When the solid phase is distinct during solidification, such as can occur in pure metals or in alloys with narrow solidification ranges, body shrinkage can easily be maintained by the reduction of the free liquid surface within the system by the external tightening riser, Shrink ...
