摘　　要：为解决注装药气孔、缩孔等疵病,提出一种基于逐层、顺序凝固原理的梯度护理凝固方法。通过沿装药弹体的轴向划分出小区间,找出最易产生装药缺陷的区间,控制冷却液面上升速度等手段来使药液在该区间内的凝固不产生疵病,完成所有区间的药液无疵病凝固,得到无明显装药疵病的高质量药柱;通过一种DNAN基熔铸炸药的梯度护理凝固应用,以验证该技术方案。装药结果表明:该方案能够得到无肉眼可见缩孔、气孔等疵病的高质量药柱,装药质量可靠。A gradient nursing solidification method based on layer by layer and sequential solidification principle was proposed to solve the defects such as gas hole and shrinkage hole of charge.By dividing a small section along the axial direction of the charge shell,find out the section most prone to charge defects,control the rising speed of the cooling liquid level and other means to make the solidification of the liquid medicine in this section free of defects,complete the defect free solidification of the liquid medicine in all sections,and obtain a high-quality grain without obvious charge defects;The technical scheme was verified by the gradient nursing solidification application of a DNAN based on melt cast explosive.The charging results show that the scheme can obtain high-quality grain without visible shrinkage,porosity and other defects,and the charging quality is reliable.
