熔铸装药凝固过程温度场变化分析

为消除熔铸装药缩孔,对凝固过程内外温度场的关联工艺进行研究.分别对普通注装、冒口漏斗注装和热芯棒注装3种工艺熔铸装药凝固过程进行实验及结果分析,通过检测壳体外部温度预判壳体内部温度变化,实现壳体内部装药质量预判,得出影响熔铸装药凝固过程的温度变化规律.结果表明:装药凝固过程壳体内部温降随时间增加而降低,装药外部温度随内部中心温度降低而降低,且均呈直线变化.

Study on Temperature Field Changes During Casting Explosive Solidification Process

For eliminating casting explosive shrinkage, research on related technique of internal and external temperature field during casting explosive solidification. Separately carry out experiment and result analysis for casting explosive solicitation process of common injection loading, feeder funnel injecting and hot mandrel. Detect shell external temperature to predicate internal temperature and realize quality predication for shell internal charging, acquire the temperature change rule which making influence on casting explosive solidification process. The results show that the shell internal temperature is higher when time increases, the charging external temperature decreases when internal center temperature decreases. The change is linear change.
