Embodiment Construction

[0027] The power source material of the proximity fuze used for explosives of the present invention is a metal material calcium strip foil made of sponge calcium raw material through smelting, surface milling, repeated rolling and annealing. Such as figure 1 Shown: Its specific processing process is: raw material→smelting→face milling→rolling→annealing→rolling→annealing→rolling→annealing→rolling→edge trimming→finished product inspection.

[0028] Below in conjunction with specific embodiment, preparation method of the present invention is illustrated:

[0029] 1. Melting:

[0030] Raw material: Sponge calcium 99.9% Loading capacity: 1.8kg per furnace

[0031] Accessories: Ar gas; welding rod; packing cloth

[0032] Equipment: furnace body and stainless steel crucible, thyristor voltage regulator; copper mold, mechanical pump for vacuum system, carbon silicon rod furnace

[0033] operate:

[0034] Clean the valves of the vacuum system, clean the furnace body and crucible a...

Abstract

The invention relates to a power supply material for a proximity fuze used for explosives, which is a metal material calcium strip foil made of sponge calcium raw material through smelting, surface milling, repeated rolling and annealing. The preparation method of the material is as follows: put the sponge calcium raw material into the crucible, then put it into the melting furnace, put the mold into the furnace to align the casting port, and fix the crucible with a clamp; connect the vacuum system to vacuum the furnace for 20 After ~40 minutes, fill Ar gas to a pressure of 0.5~1.5atm; hoist the furnace body into the carbon silicon rod furnace, power on, heat up, and adjust the air pressure at any time to keep it at 1 atm; when the furnace temperature rises to 850°C~1000°C, Lift the furnace body out and tilt the furnace to cast; after casting, air-cool the temperature for 15-30 minutes, and the cast ingot is released below 100°C; take out the cast metal Ca ingot, cut the head and mill the surface, and make metal Ca Ingot slab; blanking, rolling the ingot slab to a thickness of 8.0mm; repeated rolling, finally made into 0.6mm, trimming; rolling the obtained metal Ca plate into a metal calcium foil of the required size, according to the width requirement Trimming and slitting.

Description

technical field [0001] The invention belongs to the field of national defense industry, and in particular relates to a power source material for a proximity fuze used for explosives and a preparation method thereof. Background technique [0002] The fuze is a control device (system) that uses target information and environmental information to detonate or ignite the charge of the ammunition warhead under predetermined conditions. Different fuzes are selected according to the needs of different explosive species and targets, and the material properties of the detonation fuze power supply The superiority of the fuze also determines the advantages and disadvantages of the fuze device (system). [0003] Fuze power material performance in the prior art is not superior enough. Due to the extremely strict requirements on the materials used in the defense industry (especially the proximity fuze power supply dedicated to missiles, weapons, artillery and bombs), there is an urgent ne...
