DNAN 基含铝熔铸炸药倒药方法研究

为了重复利用不合格战斗部壳体及炸药，针对战斗部装填的 DNAN 基含铝熔铸炸药进行了特性分析，对比了机械破碎法、化学试剂溶解法、间接加热熔化法等几种常用倒药方法的优缺点，最终选定了适合该炸药体系的间接加热熔化倒药方法。同时，对倒药过程的安全性进行了分析，并利用计算模型对倒药工艺参数进行了预估。试验结果表明，计算模型预估与实际结果较为吻合。该方法的应用，既节约了成本，又避免了环境污染，实现了资源的循环使用。

Study on the Charge-inverted Method of DNAN-based Aluminized Melt-cast Explosive

In order to re-use unqualified warhead shell and its filling explosive, the characteristics of DNAN-based aluminized melt-cast explosive were analyzed. The advantages and disadvantages of several common charge inversions, including mechanical disruption, chemical dissolution, melting through indirect heating and so on, were compared. The last method was finally selected to suit this explosive system best. Meanwhile, the safety analysis was conducted in the charge-inverted process. The simulated process parameters had a good agreement with real results according to test verifica-tion. The application of this method not only can save cost, but also avoids environmental pollution to achieve the recycling of resources.
