项目摘要
Motivated by environmental protection laws and the global goal of an eco-friendly production, inorganically bonded sand cores are being used more and more often by light metal foundries around the world. These cores consists of natural quartz sand, which is bonded by silicate binders. Their technological properties mechanical strength, permeability, thermal conductivity and heat capacity are critical for the casting quality. The effect of sand and binder characteristics on these technological properties have merely been described by heuristic methods until now. The aim of this project is to develop and validate a computational method, which determines the technological properties of inorganically bonded sand cores based on the constituents' properties. The numerical method is based on a three-dimensional model of the material's microstructure.
在环境保护法和环保生产的全球目标的推动下,无机粘结砂芯正越来越多地被世界各地的轻金属铸造厂使用。这些岩芯由天然石英砂组成,由硅酸盐粘结剂粘结。它们的工艺性能、机械强度、透气性、导热系数和热容对铸件质量至关重要。到目前为止,砂和粘结剂特性对这些工艺性能的影响只能用启发式方法来描述。本项目的目的是开发和验证一种计算方法,该方法根据组分的性质来确定无机粘结砂芯的工艺特性。该数值方法基于材料微观结构的三维模型。
