摘　　要：为了提高熔铸炸药块铸装药质量,以质量比DNAN/RDX/Al:55/20/25的基础配方为研究载体,采用两种不同装药工艺进行装药对比试验,并对样品的内外部质量、装药密度及其均匀性进行分析。结果表明,与常规块铸工艺相比,采用预整形同步块铸技术所装填的药柱,其装药密度达到了1.726 g/cm3,相对密度为95.8%,与常规块铸工艺相比分别提高了0.041 g/cm3和2.2%;同时减少了装药的缺陷,使装药内外部质量获得提高,并改善了装药的密度及其均匀性。To improve the block-molded charge quality of melt-cast explosives,the comparable experiments of charge were carried out by two kinds of processes based on the formulation of DNAN / RDX / Al = 55 /20 /25（ mass ratio） as a research object. Moreover,the inner and outer quality,charge density and homogeneity of the samples were analyzed to validate the advantage of the new method. The outcomes show that,compared with conventional block-molded casting,the density of charge due to preshaping and synchronous block-molded casting reaches up to 1. 726 g / cm^3,and the relative density is 95. 8%,which increase by 0. 041 g / cm^3 and 2. 2%. Furthermore,the drawbacks of charge declined,the inner and outer charge quality was advanced,and the uniformity of charge density was improved.
