冷芯盒制芯工艺对砂芯性能影响的研究

Work on Effect of Cold box Process on Performance of Cores.

在立足于国产制芯原材料的基础上，研究了三乙胺冷芯盒工艺对砂芯性能的影响。作者利用国产原砂和粘结剂，系统地进行了冷芯盒制芯试验，研究了原砂水分、原砂温度、原砂含泥量和环境的相对湿度等制芯工艺因素对砂芯性能的影响。

Abstract Based on domestic materials used in the Phenolic Urethane Cold Box Process(PUCB),the relationships between coremaking parameters and the properties of cores have been studied.The influences of sand moisture,sand temprature,sand clay content,and relative humidity on core quality have been studied through experiments.
