It is said to be cast iron, but in fact it is all steel. Armored vehicles, helmets from the German army, and even the steel bars stripped from the ruins of Homnage are all steel with low carbon content.
The blast furnace in the Blacksmith Village has the ability to melt it, but it will inevitably be mixed with carbon elements after the casting is completed, and its performance will be reduced.
Since it is a consumable weapon, the industrial performance of the metal material is not considered much. At most, it is used to make nails. Among many products, cast iron has the largest output. On the one hand, its production process has been known for three thousand years, and on the other hand, it is only
Especially the shell of the grenade and the bullet warhead are completely used. If it is a cannonball, a blower is also needed to blow air.
A group of soldiers collected metal near the breakthrough of the shooting range. The soil here is very fine. The soldiers held a sieve and quickly screened out a large number of metal particles - these are the bullet heads.
A large number of broken iron pieces were placed in front of Yang Mingzhi and others. On the surface, the shape of the bullet head could no longer be seen.
When a standard lead-core steel bullet hits a soft target, its shape will hardly change. It should still have a streamlined shape when played in the palm of the hand. Yang Mingzhi squatted down and grabbed a handful of iron particles. There were too many irregularities here.
There are only a few fragments without severe deformation.
There are also some that are not deformed at all, and their characteristics are completely different from the others. The traces caused by scratching the rifling are clearly visible.
Yang Mingzhi held two bullets in his hand. He said to Liguschkov with big eyes: "Here, one is the warhead of a standard German bullet, shot by Besica. This one is from the arsenal."
The cast iron bullet produced was fortunately not broken, but the overall shape was changed."
Liguschkov nodded. The land at the shooting range will be cleared away after training. The metal bullets fired will not be wasted. They can still be used as waste after being recycled. These scraps of iron are all from the shooting of the youth camp. The original cylindrical round head
Most of the warheads turned into small and large pieces of iron.
"Just hitting the wood block will break it. Is there too much carbon mixed in during processing?"
"That's right, there is just too much carbon." Yang Mingzhi pinched his waist and said, "From an industrial point of view, these metals are just like waste." Liguschkov didn't want this. Pure iron is soft and mixed with iron.
The hardness of carbon increases, but it also becomes more brittle. If it hits a wooden board, it will cause a large number of fragments. Will the armored vehicle hitting the enemy turn into tiny pieces of iron everywhere? If it is such a warhead, how to ensure stable flight?
Accuracy cannot be guaranteed, and you can really only shoot at close range. The closer the distance, the more dangerous it is for soldiers.
"They cannot be processed into industrial products, but they have new uses as bullets." Yang Mingzhi said excitedly: "Liguschkov, think about it, a kind of bullet will be like a cannonball after hitting the enemy's body.
By exploding into many small pieces, it can damage the enemy to the greatest extent, and one bullet is enough to destroy the enemy's internal organs."
"Does such a bullet really exist?" Liguschkov asked in surprise.
"It must exist! After all, this is what the deputy division commander said!" Yang Mingzhi's curiosity has been completely aroused by Yang Mingzhi. This man from the East can definitely bring the power of the East. If the weapons design bureau comes up with something like this
With bullets, even soldiers with poor shooting skills can turn into a terrifying combat force.
Looking at everyone's curious looks, Yang Mingzhi pointed to the pile of iron pieces on the ground. "We all hope that the bullets will remain in their original shape after being fired. As far as the results are concerned, these inferior cast irons have been shattered, and when they come into contact with the wooden board,
It breaks instantly, or becomes multiple fragments. Such bullets have extremely poor penetrating power, but are very corrosive. If one warhead splits into multiple pieces, the effect is probably the same as being shot by a short burst of mg34."
"Isn't this the effect of dum bombs?!" Liguschkov said in surprise.
"But this is not a dummy bullet. We are too poor now to use lead at all, and all reloading bullets are made of iron. Because the only way we can obtain lead is to sift the land with a screen on the battlefield, so that those warheads can be used by us
Waste utilization.”
After saying this, everyone was happy.
Yang Mingzhi waved his hand: "We have also recorded these situations. In the afternoon, we added another German-made replica bomb experiment. In terms of results, we have gained another unexpected result. Now let's go back to the meeting."
The materials used for reloading bullets in the past were very good. Although the bullets had poor flight effects, at least they would not crack when they came into contact with the target. It may be because of the large-scale production movement, the arsenal's control over craftsmanship and quality has been reduced, and a large amount of carbon was mixed into the molten iron.
Steel also becomes scrap steel.
In fact, most metals can be used as warheads. Yang Mingzhi thought of China, which is 10,000 kilometers away. Yan Laoxi's Jinsui Army made tin bullets for a period of time. After all, this metal is very cheap. It only has a melting point that is too high.
The low, strong chamber pressure and high temperature may cause it to fly out in an almost liquid state.
Everyone was walking leisurely on the road to the research institute. Yang Mingzhi had already decided to start experimental analysis without stopping. He suddenly thought of this, and it seemed that he should make a big fuss about the bullet.
When he came to the Weapons Research Institute, Yang Mingzhi criticized Liguschkov and his wife about the failure of the rocket, because when they prepared the propellant, the first thing they mixed was less ammonium nitrate, and the second thing was a lot of ammonium nitrate.
.
After these two words were finished, Yang Mingzhi stood up and briefly stated: "Ammonium nitrate is used as a propellant additive. It should not replace potassium nitrate at present because the energy and gas generated during its chemical reaction are too strong. We know the thrust of the rocket.
It comes from the gas produced. The excessive gas expansion makes it difficult for our rocket shell to bear such pressure."
As far as the experimental results are concerned, this is the best explanation. Liguschkov admitted that he did not expect that mixing ammonium nitrate would bring about a sudden increase in power.
Yang Mingzhi took out a pen and paper and wrote down the chemical reaction equation, as well as the correct proportions of the chemicals.
"These are what I should have explained yesterday, because apart from those things, it was delayed. It is not a bad thing for the experiment to fail. From a dialectical point of view, if we fail, we will know the reason for the failure. I am afraid we will not do this again in the future.
Mistake. When the ammonium nitrate in Catfish Village is mass-produced, we will mix the propellant according to this ratio."
Liguschkov patted his chest: "I will faithfully follow the craftsmanship, but what about the explosives in the warhead?"
"There is no problem with the explosives. We still use chemical fertilizers and sawdust to replace black powder. We can produce ammunition with extremely high cost performance."
Compared with the problem of bullets, the problem of rockets is easier to solve. The faster initialization will make the RPG more accurate. To deal with long-distance targets, shooters no longer need to adjust the shooting angle based on experience and belief. They only need to aim the mechanical sight at the enemy tank.
Yang Mingzhi said jokingly: "Follow my orders and our soldiers can easily do it."
"So it will be so easy to attack enemy tanks in the future?" Liguschkov was excited in his heart. "With stronger thrust, we can shoot out warheads with larger charges. Even if the enemy increases the thickness of the armor,
We can still hit it head-on."
"Of course! Let me remind you that Catfish Village will also provide a large number of high-energy fuel weapons." Yang Mingzhi wrote down the chemical formula of hydrazine hydrate and pointed at it: "Special warheads produced using this compound as raw materials,
It is the most powerful weapon we will equip in the future. You must also be careful during production. I will personally guide you then."
"Sir, don't worry, I will complete the task." Liguschkov's straight waist is reassuring.
Yang Mingzhi nodded with satisfaction and started the topic of hollow point bullets.8
