Chemically bonded sand systems are an important and growing part of foundry technology, and their interaction at the mold–steel interface is of great interest. With today’s emphasis on near-net-shape steel castings, and with ever more stringent casting quality requirements, there is a need to quickly and affordably characterize as-cast surface quality. In addition, characterizing shakeout performance is necessary to meet today’s steel casting efficiency requirements. New AFS standard tests using disk-shaped specimens (AFS 3344-18-S), such as the thermal distortion test (AFS 3350-18-S), have proved to be efficient and effective techniques for detecting anomalies and measuring distortions for chemically bonded sand binder systems. However, these laboratory tests are unable to address all the influences at the mold–steel interface. Furthermore, simulation software is not yet able to predict mold/steel interfacial conditions. Thus, performing actual casting trials remains necessary. This paper aims to investigate, for steel castings, the effects different chemically bonded sand systems have towards shakeout performance and as-cast surface quality. An improved steel casting trial, using disk-shaped specimens, that allows several core specimens to be wetted simultaneously was employed. As-cast surface quality was assessed using a state-of-the-art 3D macroscope. Results suggest that various chemically bonded sand systems provide different shakeout performances and as-cast surfaces.

化学粘结砂系统是铸造技术的重要且成长中的一部分，并且它们在模具-钢界面处的相互作用引起了极大的兴趣。随着当今对近净形钢铸件的重视以及对铸件质量要求的日益严格，需要快速而经济地表征铸态表面质量。此外，表征振动性能对于满足当今的钢铸效率要求是必要的。新的使用圆盘状试样（AFS 3344-18-S）的AFS标准测试，例如热变形测试（AFS 3350-18-S），已被证明是检测化学键合异常和测量变形的有效技术。砂粘结剂系统。但是，这些实验室测试无法解决模具-钢界面处的所有影响。此外，模拟软件尚无法预测模具/钢的界面状况。因此，进行实际的铸造试验仍然是必要的。本文旨在研究铸钢件不同化学结合砂体系对砂浆性能和铸态表面质量的影响。使用了改进的钢铸件试验，该试验使用盘状试样，该试样允许同时润湿多个芯试样。使用最新的3D宏观镜评估铸态表面质量。结果表明，各种化学粘结砂体系具有不同的破碎性能和铸态表面。不同化学粘结砂体系对砂浆性能和铸态表面质量的影响。使用了改进的钢铸件试验，该试验使用盘状试样，该试样允许同时润湿多个芯试样。使用最新的3D宏观镜评估铸态表面质量。结果表明，各种化学粘结砂体系具有不同的破碎性能和铸态表面。不同化学粘结砂体系对砂浆性能和铸态表面质量的影响。使用了改进的钢铸件试验，该试验使用盘状试样，该试样允许同时润湿多个芯试样。使用最新的3D宏观镜评估铸态表面质量。结果表明，各种化学粘结砂体系具有不同的破碎性能和铸态表面。
