一、前言本文主要介绍在整个铸造过程中铸造金属的质量及质量如何测量和改进的问题。“铸造金属质量”这一概念直接与铸造金属工业怎样对质量下定义有关。一方面,对一般铸造经营者而言,铸件质量的提高可用废品率降低来表示。另一方面,对冶金学家或材料工程师来说,铸件质量可用其机械性能表 I. Preface This article mainly introduces the problem of how to measure and improve the quality and quality of foundry metal in the entire casting process. The concept of “cast-metal quality” is directly related to how the foundry industry defines quality. On the one hand, for general foundry operators, the improvement of the quality of castings can be expressed in terms of the reduction of the reject rate. On the other hand, for metallurgists or material engineers, the quality of the castings can be characterized by their mechanical properties
