针对某结构铝合金压力容器在铸造生产中出现孔洞缺陷这一常见现象,结合容器结构分析缺陷形成原因,提出在专用冷铁上刷清漆并覆盖干砂的工艺措施。实践证明,采用该工艺可有效地消除孔洞缺陷。
Aiming at the common phenomenon that a certain structure aluminum alloy pressure vessel has hole defects in foundry production and combined with the reason of container structure analysis defects, the paper puts forward the technical measures of brushing varnish on special cold iron and covering dry sand. Practice has proved that the use of the process can effectively eliminate the hole defects.
