Abstract
The invention discloses a cast explosive circulation diameter testing device. The cast explosive circulation diameter testing device solves the problem that the minimum circulation diameter of current cast explosives is not quantified. The cast explosive circulation diameter testing device is composed of a building block opening and closing type variable-diameter circulating pipe, a heating jacket and a heat-preserving layer. The building block opening and closing type variable-diameter circulating pipe is composed of circulating segments of different inner diameter specifications of 50 mm, 45 mm, 40 mm, 35 mm, 30 mm, 25 mm, 20 mm, 15 mm, 10 mm, 8 mm, 5 mm and 3 mm, and each circulating segment is of an opening and closing type structure. When cast explosive slurry flows through the building block opening and closing type variable-diameter circulating pipe, the diameter of a minimum-stage pipe body where explosive slurry is not deposited serves as the circulating diameter of explosives at the temperature. The heating jacket can be connected with a circulating oil bath, and therefore the circulating diameters of the cast explosives at different temperatures can be tested. The cast explosive circulation diameter testing device can be used in the technical field of technical study of the cast explosives, and the device has great significance in guiding design and optimization of the cast explosive formula improving the filling quality of the cast explosives in the warhead.
