摘要

摘要在铸造方法中，正确地进行造型设计以生产出良好的零件是至关重要的。体积变化，尤其是在球墨铸铁凝固过程中，与钢铸件和铝铸件相比，可能表现出不同的行为。在本研究中，在不同横截面厚度的生砂和树脂型砂的铸造参数下，用单进料器和双进料器进行了铸造。根据化学成分、模具刚度和接种效率，以及进料器路径的重要性，通过实验和建模技术进行了评估。因此，可以观察到，在相同的造型设计中，树脂模具中的收缩风险小于生砂铸件。此外，还发现进料器的数量和颈部连接是孔隙形成的一个重要参数。

MODELLING AND VALIDATION OF EFFECT OF BINDER TYPE ON FEEDING BEHAVIOUR OF SPHEROIDAL GRAPHITE CAST IRON

ABSTRACT In the casting method, it is crucial to properly make the moulding design to produce sound parts. Volumetric change, especially during the solidification of spheroidal graphite cast irons, may show different behaviour compared to steel and aluminium castings. In this study, castings were carried out with single and double feeders with varying casting parameters of green sand and resin mould sand containing different cross-sectional thicknesses. Depending on the chemical composition, mould rigidity and inoculation efficiency, and the importance of the feeder path was evaluated by experimental and modelling techniques. Consequently, it was observed that the risk of shrinkage in resin moulds is less than in green sand castings in the same moulding design. In addition, it has been found that the number of feeders and neck connection is an important parameter in pore formation.

期刊介绍： The International Journal of Cast Metals Research is devoted to the dissemination of peer reviewed information on the science and engineering of cast metals, solidification and casting processes. Assured production of high integrity castings requires an integrated approach that optimises casting, mould and gating design; mould materials and binders; alloy composition and microstructure; metal melting, modification and handling; dimensional control; and finishing and post-treatment of the casting. The Journal reports advances in both the fundamental science and materials and production engineering contributing to the successful manufacture of fit for purpose castings.
