本研究介绍了一项研究结果，该研究描述了熔模铸造模具的热物理特性，该模具由二氧化锆/铝酸钴底浆和熔融二氧化硅/纤维增强备用浆料组成。铸造行业中成功的计算机模拟的日益普及使得铸造过程中出现的缺陷变得越来越可预测，从而为试铸提供了经济高效的替代方案。这些模拟作为预测的可行性在很大程度上取决于通过本次调查获得的准确材料特性数据的便利性。利用差示扫描量热法（DSC）和激光闪光分析（LFA）分别测定比热容和热扩散率。这些值与材料密度和线性热膨胀系数相结合，用于确定模具的导热率。为了验证这些参数，我们在 Flow-3D® 仿真软件中进行了初步研究，以确定减少仿真参数变异性所需的约束。由于整个行业使用的铸造模具的多样性，确保材料数据库尽可能全面地填充是一项至关重要的任务。
This study presents the results of an investigation that characterises the thermophysical properties of an investment casting mould, comprising of a Zirconium dioxide/Cobalt aluminate prime slurry and a fused Silica/fibre reinforced backup slurry. Growing prevalence of successful computer simulations within the foundry industry enables defects that emerge during the casting process to become increasingly predictable, providing cost-effective alternatives to trial castings. The viability of these simulations as predictors is heavily dependent upon the facilitation of accurate material property data, as attained through this investigation. Differential scanning calorimetry (DSC) and laser flash analysis (LFA) were utilized to determine the specific heat capacity and thermal diffusivity, respectively. These values, in combination with the material density and linear coefficient of thermal expansion, have been used to determine the thermal conductivity of the mould. With the aim of verifying these parameters, initial studies in Flow-3D®simulation software have been performed to determine the constraints needed to reduce variability in simulation parameters. Due to the diversity of casting moulds used throughout the industry, ensuring the material database is kept as comprehensively populated as possible is a crucial undertaking.
