摘　　要：基于多年从事差压铸造工艺试验及研究的经验及数据,结合差压铸造理论,就铝合金差压铸造件产生粘砂的特点及原因进行了深入的研究和总结。研究结果表明,影响其粘砂的因素主要有铸造用砂及型砂本身物理特性、结壳时间、结晶增压压力、铸型(芯)表面质量、充型速度、铸件局部过热等因素的影响,并就上述影响因素提出了相应的解决措施。Base on study experience, experimental data and theory knowledge in differential pressure casting process, the character and cause of bonded sand in differential pressure casting was studied. The results indicate that the influence factors on differential pressure casting bonded sand mainly have casting sand and itself physical property, investing time, crystal pressurization, mold surface quality, filling speed and casting part superheating, aimed at above factors, the corresponding solution is supplied.
