摘要
结合水模拟、计算机模拟和X射线实时观察三个不同发展阶段,叙述了铸件充型与凝固由不可见到可见的过程,初步提出了可视化铸造的概念。它是指将计算机模拟与X射线实时观察相结合,进行铸件浇注系统优化设计的新技术。结合实例说明可视化铸造技术的应用将会克服传统的浇注系统设计引起的卷气、夹杂、冒口尺寸过大等缺陷,实现铸件的近终形铸造。
Based on three stages of water simulation, computer simulation and X-ray real time observation, this paper summarizes the history of liquid metal filling and solidification in casting process from non-visible to visible, and presents the latest concept of view-cast as the initial step. Combining the computer simulation with X-ray real time observation, view-cast is a novel technique used for optimizing design of filling system. The examples are given to illustrate that the application of view-cast technique will overcome the defects of conventional filling system, such as entrapment of air, inclusions and oversized feeder etc, and fulfill the near-net shape castings.
