- a second explosive layer 32 may be formed on the lower surface of the bottom plate 21. Blowing can be performed more reliably.
- FIG. 5 shows a pressure vessel 1 for the blast treatment.
- the pressure vessel 1 is a steel pressure vessel having an inner diameter of less than 2 meters and a capacity of about 7 cubic meters, in which a protective cylinder 2 made of high-strength steel is housed with its axis oriented sideways. I have.

- the SEP explosive layer 32 first explodes from the portion of the line detonator 24, and the explosion causes the inner ANFO explosive layer 31 to explode while being compressed. Even when using inexpensive and low explosive explosives such as the ANFO explosive layer 31, a strong detonation can be obtained. Therefore, an effective and low-cost blast treatment method can be provided. Also, the ANFO explosive layer With the 31 detonation vectors pointing inward, the scattering velocity of debris particles in the ⁇ shell (ie, the outer shell 10, inner cylinder 11, and lid 14, etc. of the red bullet) is directed inward. The detonation force is the pressure of the shock wave due to the detonation, and the detonation vector is the direction of the shock wave due to the detonation.
- both the ANFO explosive layer 31 and the SEP explosive layer 32 are arranged symmetrically with respect to the axis of red A as an object to be processed, and the detonation point (the line detonator) of the SEP explosive layer 32 24) is located on this axis. Therefore, the detonation of the SEP explosive layer 32 has a large effect of compressing the ANFO explosive layer 31 because the propagation of the detonation is also performed while maintaining the axial symmetry, and a larger detonation force of the ANFO explosive layer 31 can be obtained. .
- the cylinder 22 having the SEP explosive layer 32 disposed thereon is covered with the red ammunition A, and the granular ANFO explosive layer 31 is inserted between the cylinder 22 and the red ammunition A. It is easy to make the ANFO explosive layer 31 and the SEP explosive layer 32 surround the red bullet A. Therefore, the process for the blast treatment can be simplified.
- the structure of the red simulant ⁇ A is slightly smaller than the 15 kg red simulant ⁇ (FIG. 1), and the dimensions of the main part are as follows. 80 mm height, inner cylinder 11 dimensions 44 mm diameter, height 295 mm diameter, outer shell 10 dimensions 74 mm diameter M, height 302.5 mm.
- the outer shell 10, the inner cylinder 11, the inner lid 12, the explosive cartridge 13, and the lid 14 were all made of SS400 steel.
- a first explosive (ANFO explosive) layer 31 is formed on the outer periphery of the simulated ⁇ A in a uniform thickness so as to have a thickness of about 10 millimeters by a method similar to that shown in Fig. 2 (a)-Fig. 4.
- a second explosive (SEP explosive) layer 32 having a thickness of 5 mm was further formed on the outer periphery and the upper surface side. The amount of explosives used was 815 grams for ANFO explosives and 733 grams for SEP explosives. Then, after setting the line detonator 24 at the center of the EP explosive layer 32 on the upper surface side, put the whole into a bag 25 as shown in FIG. The inside of the container 1 was sealed, the inside was evacuated, and the reactor was detonated.
- the 580MPa class high-tensile steel sheet with a thickness of 50mm used in this experiment withstands a greater number of blasting treatments than before, and the frequency of replacement is reduced.
- a simulated ammunition was created that was larger than the 75 mm diameter red bullet used in Experiment 1 and imitated the 15 kg red bullet as shown in Figure 1.
- the main dimensions of the red bullet A are as follows: the size of the explosive cartridge 13 is 30 mm in diameter, 123 mm in height, the inner cylinder 11 is 64 mm in diameter, the height is 350 mm, and the outer shell 10 is 100 mm in diameter. The height was 380 millimeters.
- the TNT explosive was loaded into both the inside of the explosive cartridge 13 of the red mock-up A and the inside of the inner cylinder 11.
- the TNT charge was 667 grams.
- 293.6 g of a simulated agent (Octanol) simulating a red agent was loaded.
- a first explosive layer 31 that is, an ANFO explosive layer
- a second explosive layer 32 ie, a sheet explosive (SEP explosive) layer.
- the explosives used were 1379 grams for ANFO explosives and 1099 grams for SEP explosives.
- the detonation speed of the explosive was calculated as 4.23 km Zsec for the TNT explosive, 6.15 km Z sec for the SEP explosive, and 3,000 km / sec for the ANFO explosive.
- the speed of the shock wave in SS400 steel was set at 5 km / sec, and it was assumed that the detonation would start as soon as the shock wave reached the surface of the explosive.
- the treatment was the same as that for SS400 steel without any particular consideration. In the simulation model for calculation, the cylinder 22 and the lid 23 were omitted.
- FIG. 7 shows a calculation result in the form of a half-sectional view. According to the results shown in FIG. 7, the detonation process takes about 75 ⁇ s from the ignition by the wire detonator 24 to the end of the propagation of the detonation wave. In the initial stage, the explosives detonate SEP, ANFO, and TNT.
- the direction of the detonation wave of the ANFO explosive layer 31 is outward, but as time elapses, that is, as the detonation progresses, the height of the SEP explosive layer 32 rises. Dragged by the detonation speed, after 50 / sec, the direction of the detonation wave (detonation vector) must be inward. Therefore, after 50 ⁇ s, the flying speed of shell fragment particles becomes inward. It is considered that this reduces the outward speed of the shell fragments and contributes to the reduction of the damage of the protective cylinder 2.
- the explosive starts detonating about 8 ⁇ s after the detonation due to the shock wave propagating through the SS400 steel lid 14, and the detonation wave propagates from above to below.
- the direction of the detonation wave is gradually inclined inward, being dragged by the high shock wave velocity of the inner cylinder 11 made of SS400 steel. This is also considered to have the effect of reducing the velocity of the ⁇ shell debris going outward.
- FIG. 8 As a reference experiment, another simulation model (FIG. 8) different from the above was calculated under the same conditions as above.
- the simulation model of FIG. 8 has two features. First, a space without the ANFO explosive layer 31 is formed between the warhead (cover 14) of the red bullet and the detonator 24. Second, the SEP explosive layer 32 covering the warhead side of the simulated ammunition A is conical Is formed.
- the SEP explosive layer 32 (conical portion) first starts detonation by detonation by the line detonator 24, and the direct transmission of the detonation wave to the lid 14 is based on the aforementioned space. Is blocked by Accordingly, the detonation wave is transmitted from the outside to the ANFO explosive layer 31 bypassing the line detonator 24.
- the detonation vector of the ANF ⁇ explosive layer 31 has already turned inward from the initial stage (after about 20 ⁇ s). Therefore, it can be seen that by providing a space between the detonator 24 and the warhead as in the model in FIG. 8, the scattering speed of the fragments of the shell shell can be more inwardly directed than in the model in FIG.
- an ANFO explosive 31 forming the first explosive layer 31 is placed below the red bomb ⁇ and an SEP explosive forming the second explosive layer 32 is arranged below the ANF explosive 31.
- the ANFO explosive layer 31 below the red bomb A is continuous with the ANFO explosive layer 31 around the red bomb A
- the SEP explosive layer 32 below the red bomb A is the red A and the ANFO explosive layer 31.
- the first explosive layer and the second explosive layer which are arranged on the outer periphery of the red ammunition A, are made to wrap around to the lower surface side of the red ammunition A (tail side). By doing so, it is thought that the flying speed of the shell fragments in the downward direction can also be reduced.
