摘要

简要分析了铝合金消失模铸造中常见的缺陷

如表面针孔、渣孔

气孔、夹渣孔、夹砂

粘砂、结瘤

缩孔、缩松

溃型

冷隔、重皮

浇不足

表面孔洞与凹坑

碳缺陷

球粒状表面和表面过烧

表面凹凸现象等

并指出造成缺陷的原因和防止措施。认为铝合金吸气、氧化是造成铸件缺陷的最主要原因

为避免缺陷的产生

应严格控制生产工艺的各个环节。

Abstract

Lost foam casting aluminum alloy parts is increasingly applied in automobile industry

such as engine cylinder

cylinder cover

manifold exhausted pipe with water cooling

valve

nozzle at abroad.However

lost foam casting aluminum alloy parts is slowly developed at home

which was attributed to complex processing

low equipment and raw and auxiliary materials resulting in casting defects.Origination of main defects in lost foam casting aluminum alloy parts and countermeasures were described.
