Yesterday, Hanhai Wolf Mountain has already talked about the fact that because the shells that are poured into cylinders by modern mainstream explosives such as TNT and Hesokin have a process of being in a semi-melted and semi-fluid state, and its internal temperature is generally above 80 degrees Celsius, and finally it is naturally cooled to the level of room temperature, and then solidified into a solid state. Therefore, the explosive filling of artillery shells is actually a pouring process. Any pouring process, including the most common pouring cement on buildings, can be carried out in three ways: pure manual, semi-manual and semi-automatic, and fully automatic mechanical filling. According to common sense, it is easy to understand: the production efficiency of pure manual pouring is the lowest, the efficiency of semi-manual and semi-automatic mode is higher, and the pure automatic assembly line filling production efficiency is the highest, which is completely incomparable with manual pouring. However, the problem is that as a pillar type of munitions product with extremely high safety factor requirements, in addition to production efficiency, the requirements for safety and quality must not be reduced at all; otherwise, the shells produced will easily explode.
As a result, all front-line artillery did not dare to use certain batches of shells, and as a result, the war did not have to be carried out, and they themselves automatically raised the white flag first. So pure manual, semi-automatic and fully automatic filling, without discussing the output first, which mode of pouring shells has the best quality? This really cannot be generalized. This is because if the person who pours the warhead of an artillery shell or missile is a unique expert in ammunition, then the warhead of the shell or missile that is poured by this person by hand is often a perfect craft. The warheads of some super-missiles of various military powers, especially the initiating charges used to detonate HE warheads, are basically poured by hand by such military masters. Moreover, after pouring the blank of explosives, it is necessary to remove microscopic defects like carving, so that the product is absolutely perfect and reliable. However, the relative disadvantage is that this kind of master figure who carves explosives only exists in single digits even if it is a big country. If used to produce ordinary,
Large-caliber shells, then only a few dozen rounds can be produced in a year. Obviously, it is far from the needs of real combat. So can we find more apprentices for the masters of dynamite carving, such as training dozens or even hundreds of people at a time? The effect of this is also average! Because famous teachers may not produce high-level apprentices, and most people are relatively mediocre existences. Hundreds of apprentices each have an electric kettle, and the final poured cannonball will inevitably have a small number of cracks and bubbles. And even if 1 of 1,000 shells has a gap that causes a martyrdom, then it is very deadly. Each person has an electric kettle, which is mainly used to keep the explosives in a melted state warm. Before filling, the empty shells in the cylinder state should also be heated. This ensures that air bubbles and natural voids are minimized during the pouring process. But that's not enough. The best way to ensure that the shells are basically free of gaps after pouring solidification is to add a certain amount of additional internal pressure to the concentrated syrup-like explosives in the pouring process. Thus poured into the cylinder,
explosives will greatly reduce the probability of bubbles and bottom gaps. In order to make semi-fluidity explosives generally have internal pressure, and the amount of each pouring is very standard, it will not easily overflow, which is naturally achieved by a fully automatic filling production line. All of the above are very basic industrial principles, so why is the whole of NATO still pouring them manually? The most important thing is actually two points: First, it is the explosives during the pouring period, which are best to be synthesized and poured immediately; to put it bluntly, it is to strike while the iron is hot, and the quantity is preferable. Directly a large cauldron, hundreds of thousands of tons are added to the reactor, and the heating belt is pressurized and then fully automatically filled, producing tens of thousands to hundreds of thousands of large-caliber shells at one time. However, at present, NATO's explosives, including propellants, are all imported from a large East Asian country, and the technological basis for pouring large volumes while synthesizing has been completely lost. It can only be eaten after the start of work. A batch of imported raw materials is boiled in a small pot on site, and then a kettle is generated by a kettle workshop for one person. The second reason is also crucial.
This is why a certain big country completely solved the problem of accurate quality inspection of a large number of finished artillery shells through an extremely ingenious way as early as 20 years ago. It is possible to ensure that not a single round of new shells with serious quality defects will be ensured. To this day, the entire NATO system still needs to pass every new artillery shell through an X-ray machine, and even for each batch of 500 shells, one round has to be sawed on the spot for visual inspection. And there are more than 20 large-caliber artillery shell filling lines in the world, and they are all in a big country. If there are enough orders, it is not a problem to deliver a million rounds a day and a night. Is this to envy the rhythm of the entire United States and the West?
