文献名称：低压铸造缩孔缩松判据预测技术

    前言：本文考虑了压力对临界固相率的影响 ,提出了压力下的缩孔预测判据 ,及与压力、温度梯度和冷却速度相关的缩松预测判据 ,该判据已成功的应用于华北工学院铸造工程中心开发的Castsoft软件的低压铸造模块
    In this paper, the influence of the pressure on the critical solid fraction was considered; the critical solid fraction method under the pressure condition was proposed to predict porosity. On the other hand, based on the darcy law, a new shrinkage prediction method related to pressure, temperature gradient and cooling rate was put out. The criterion had been successfully applied in the low-pressure casting module of castsoft, which had been developed by the casting centre of North China Institute of Techno...
