粉末药型罩铸造过程中粉粒大小和形状对射流性能的影响

Influence of Powder Particle Size and Shape of Powder Liners on Jet Performance in Casting Process

对钨铜粉末药型罩静破甲试验进行了分析。结果表明:改变药型罩中钨、铜粉粒的大小和形状,可以改变药型罩在铸造过程中的密实性、颗粒级配、流动性、压缩性和成形性,进而影响射流的性能。

The static ballistic tests on powder shaped charge liners cast with tungsten and copper powder were analyzed. The results show that changing the size and shape of tungsten-copper powder particle in powder liners can change its density, particle arrangement, mobility, compressibility and formability in the process of foundry, and then affect the performance of jet.
