Abstract

Abstract

We studied the effect of the explosive mass and the heating rate on the slow cook-off characteristics of DNAN based casting explosive by designing a new roasting test device, and examined the thermal reaction characteristics of the mixed explosive by performing a multipoint temperature experiment at two heating rates, 1℃/min and 0.055℃/min, respectively. The results showed that the explosive mass and the heating rate jointly affected the response characteristics of the roasting bombs. The same roasting bombs at the heating rate of 0.055℃/min was more intense than that at the heating rate of 1℃/min. The placement posture and the thickness of the end cover also affected the intensity of the response of the roasting bombs.
