摘要
以ZL205A厚大舱体铸件为研究对象,针对舱体铸件的特点,开展了铸造工艺方案设计、铸造工艺方案数值仿真计算及熔体处理等技术的研究.研究结果表明:铸件采用差压浇注方法,低热量浇注系统,配合低热量浇注系统使用的冷铁,铸件实现了顺序凝固;铸件经检测,内部质量优良,切取试样力学性能远超过了指标值,各项指标均满足设计要求.
Abstract
The research focused on the process of the ZL205A thick-walled cabin casting.Based on the characteristics of the cabin casting,the study conducted research on the design of casting process,numerical simulation calculations of casting process,and molten metal treatment techniques.The research results showed that by using the counter-pressure pouring method and a low heat pouring system with the assistance of chills,the casting achieved sequential solidification.The internal quality of the casting was excellent,and the mechanical properties exceeded the specified values.All indicators met the design requirements.
