According to statistics, our country produces about 2 billion bullets per year, which sounds like a huge number, so how much does it cost our country to produce these bullets every year? Produce so many bullets and end up using them all**?
According to historical records, in 1132 A.D., there was a person named Chen Gui in the Song Dynasty, he invented a musket without bullets, and the musket invented by Chen Gui was filled with gunpowder, and then in 1259 A.D., there was a sudden musket in China, which was the earliest rifle in China, and the muzzle was loaded with bullets.
At that time, the cost of making bullets was very low, and the materials used to make bullets were cheap materials such as broken porcelain, broken iron, and crushed stones, and the cost was negligible.
During the Anti-Japanese War, China's economic level was low, the technology and cost of making bullets were high, an ordinary bullet needed about 5 cents, in that era, the value of 5 cents was very high, and later the victory of the Anti-Japanese War, China's industrial level gradually improved, and the manufacturing technology was also **, the cost of bullet manufacturing was finally reduced, and the average bullet was about 6 cents.
But no matter how low the cost of bullets is, the amount of ammunition used will not change, such as a machine gun, when the trigger is pulled, a hundred rounds of ammunition are gone.
So how much has it cost to manufacture bullets in our country now?
Before that, let's take a look at the composition of bullets, starting with the most commonly used 5For example, an 8mm bullet is mainly composed of a warhead, a cartridge case, a propellant and a primer, and the cost of manufacturing a bullet is divided into raw material costs, labor costs, and manufacturing costs.
Among them, the raw material used in the manufacture of bullet casings can be brass, because brass has good ductility and heat resistance, the bullet will produce huge heat when fired, if the heat resistance is not strong, can not withstand the heat and pressure generated during shooting, then the shape of the bullet will definitely change shape during the firing process.
In addition, the size of the bullet also has strict requirements, and the size, shape, smoothness, and curvature of the bullet must be paid attention to in the manufacturing process.
When a bullet made of brass is fired, it expands, but this expansion will not change the shape of the bullet too much and wear out the gun, but will make the bullet evenly stressed and enhance its accuracy.
There is also a material that can also make bullets, that is, steel, although the ** of this material is lower than brass, but the ductility and heat resistance of this material are not strong enough, and it will wear out the gun when used and shorten the life cycle of the gun.
China's copper ore resources are not much, only tens of millions of tons are also difficult to mine, expensive, but China's iron ore resources are very rich, so China's raw materials for making bullets are steel, but China's bullets will not be a problem, because China has developed copper-clad steel and painted steel technology.
It only costs more than 5,000 yuan to make a ton of copper-clad steel, and it only takes about 0 to make bullets with it031 yuan, you can cut the steel bar into a section, and then cover it with a thin layer of copper, or paint it with green or brown paint, which can enhance the lubrication of the bullet, so the bullet finally produced in China is army green.
The bullet warhead, shell, lead sleeve, steel core, gunpowder and primer are also very important, the moment the bullet is launched, the shell of the bullet will produce huge friction with the inside, and a lot of heat will be generated, so the material of the bullet shell is also very important, it must have two characteristics of high melting point and strong hardness, otherwise it will not be able to withstand the heat generated when the bullet is fired.
Therefore, the shell part of my country is made of copper-plated steel, and the shell part of a bullet needs about 276 grams of copper-plated steel, according to the current market, the cost of a bullet shell is only about 0055 yuan.
The lead sleeve, that is, the bullet core in the middle of the bullet and the stuff filled in the middle of the shell, when the bullet is fired, it needs to be used to cushion the pressure of rifling extrusion, to avoid serious damage to the rifling, to create a 58 mm bullet lead sleeve, only about 0623 grams of lead, now the lead on the market ** is also quite cheap, a ton only needs more than 10,000, evenly shared, a bullet of the lead sleeve only needs about 00096 yuan.
Then there is the steel core, the steel core of the bullet is made of different materials from other parts, it uses a carbon content of less than 025% carbon steel, this kind of carbon steel, both strength and hardness are relatively low, it is more convenient to process, especially when pouring molding.
This material is not easy to cause damage to the mold, the amount of consumables is very low, and this carbon steel is not expensive now, a ton is about 4000 yuan, calculated, a 5An 8mm bullet steel core requires about 00058 yuan.
The gunpowder part is more expensive than the previous ones, in the early days, the gunpowder used in the launch of bullets in China was black powder, but now the material is no longer known, and it belongs to the secrets of the national industry, so here we take black powder as an example to calculate the cost, a bullet needs about 281 grams of black powder, ** at 0045 yuan or so.
The last part is the primer, the primer is a part that needs to be installed independently, generally installed at the bottom of the bullet barrel, and its cost is only about 1 cent, Lin Lin will finally find that the total cost of a bullet is only a few cents, but in fact, there are labor costs and manufacturing costs.
China manufactures about 2 billion bullets every year, the production process of a bullet is extremely complex and rigorous, the warhead shell and bullet core need to be stealth processing, and the assembly process in the middle also has four steps, among them, the assembly of the shell and the bullet core is the most technical step for the whole bullet, once it goes wrong, the bullet may be scrapped, but China now has a global digital machine tool production technology, and it has been possible to assemble the warhead part with low loss.
In other words, for a bullet to come out, it needs to go through several steps to complete. And the production of the shell is not simple, after having the raw materials, it also needs to be mechanically extruded to make it form, this processing process is complex, very troublesome, and then it is necessary to pickle the metal of the extrusion molding, stealth space and other six processes, in order to be able to create a qualified shell in all aspects.
At this point, many people must think that this bullet has been made, but in fact it is not, if you want to make it a bullet that can go to the battlefield, you also need to install a primer on the cartridge case, the primer is equivalent to the switch of the bullet, whether it is the production process, or the transportation process can not be wrong.
If something goes wrong, the bullet is wasted, and the life of the staff who make the bullet is threatened, so when making the primer, China will use machine tools, which can reduce the error caused by manual operation, not only to improve the safety of the production process, but also to improve production efficiency.
After the primer is installed, the sealing paint will be applied between the primer and the cartridge casing to avoid the primer from being damp during transportation and losing its effect, after that, the finished bullet casing will enter the assembly production workshop, load the gunpowder that has been weighed long ago, load the warhead, and finally pass the test before the bullet can be considered to be successfully manufactured.
The official has never announced the technical costs, personnel salaries, transportation costs and other costs required to manufacture a bullet, but according to the data calculated by the simulation, China produces a 5The cost of 8 mm bullets is about 8 yuan, on the other hand, the United States has made a bullet more than twice as much as China, therefore, the cost of manufacturing bullets in China is not expensive, if the United States and China produce about 2 billion bullets a year, then the United States will spend about 60 billion yuan a year on bullet manufacturing.
So, what about the production of so many bullets in my country?
The situation in the world is very changeable, no one can predict when a war will break out, such as the conflict between Russia and Ukraine, at the beginning no one would have imagined that two countries would actually fight, and even fought for more than a year.
Not taking the initiative to provoke a war does not mean that we are afraid of war, and our country is in such a turbulent situation, so it is natural that we need to make adequate military preparations to deal with the war that may come in the future.
During World War II, on the battlefield full of **, it took about 2,000 bullets to kill a soldier, but now science and technology are more developed than before, all kinds of combat aircraft, artillery and tanks emerge in an endless stream, and no matter how weak the country, its military strength has been enhanced to varying degrees.
Therefore, even in peacetime, our country needs to produce more bullets in case of emergency.
And the bullets produced in our country are usually piled up in warehouses for the daily training of soldiers, good soldiers are trained, a sniper wants to become a qualified sniper, but also needs to use bullets for shooting training, and a sniper needs about 30,000 bullets a year, there are many snipers in our country, and the training of snipers alone will consume a lot of bullets, not to mention the navy, army and other services.
With the progress of science and technology, guns will also be improved, and after the improvement of guns, the corresponding bullets will naturally not be used, and these ammunition can be given to other countries.
At present, there are still many countries in the world whose armed forces are in the initial stage, and by selling them bullets that do not conform to the development of our own country, our country can not only help other countries develop and promote friendship between the two countries, but also properly handle these bullets of our country.
