用于缸体缸盖生产的三乙胺法冷芯盒制芯工艺研究

Triethylamine Cold Box Core-Making Technique for Cylinder Block and Head Castings

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。利用苏州兴业产的树脂,系统地进行了冷芯盒制芯试验,研究了原砂水分、原砂吸水性能、树脂配比工艺、吹胺时间和环境的相对湿度等制芯工艺因素对砂芯性能的影响。

Based on domestic materials used in the Phenolic Urethane Cold Box Process （PUCB）, the relationship between core making technique and the properties of core was analyzed. The influences of sand moisture, sand water absorption, proportion of resin, time of amine blowing and relative humidity on core quality were studied through experiments.
