This is not because Zhang Wanhe did this intentionally, but Su Xin's third factory was originally responsible for manufacturing reloading bullets and grenades, and it was also the most important branch factory that could even be said to coordinate the overall situation.
Several other branches, such as the first branch focusing on turning processing, the second branch responsible for casting, and the fourth branch responsible for gunpowder, do not have the ability to grasp the overall situation like the third branch.
Su Xin organized her thoughts and said in an orderly manner:
"Not long ago we considered the issue of grenades and successfully produced two hundred grenades."
"After using toughening technology, the power of grenades has indeed been improved."
"As we expected before, the grenade has more charges and the shrapnel becomes thinner, so the fragments exploded with more fragments and a wider killing radius."
"The phenomenon of one being blown in half like before basically no longer exists."
"But its power is still insufficient and unstable."
"According to our experiments, the number of fragments is between five and fifteen, and the initial estimate of the killing radius is about four meters."
Seeing Zhang Wanhe hand Wang Xuexin a piece of test data, Su Xin continued:
"We analyzed and compared these data and believe that the lack of power is mainly caused by uneven fragmentation."
"The effect of our local toughening method is not ideal, and it will lead to uneven toughening."
"So different parts of the same grenade have different hardness and different toughness."
"Not only does this have a high scrap rate, which seriously affects production, it also causes the fragments produced when the grenade explodes to vary in size."
"As a result, small shrapnel is too small and has no lethality. Large shrapnel cannot fly far and has no lethality."
Wang Xuexin understood after hearing this.
The Japanese grenade is made of prefabricated fragments, that is, grooves are made on the surface of the grenade. Coupled with the toughness and uniform hardness of the shell, when it explodes, it will basically break from the grooves to produce fragments of similar sizes.
These fragments are both lethal and fly as far as possible, thus maximizing their power.
However, the border area grenade with local toughness cannot do this.
Zhang Wanhe continued: "We also thought about putting grooves on the projectile like the Japanese to make the fragments more even and fragmented. But..."
As he spoke, Zhang Wanhe turned his attention to hardware.
The hardware responsible for the turning process replied: "The grenade has a small body and thin wall, and the different toughness makes it very difficult to process. The scrap rate is as high as 70%. However... the power of the processed grenade is indeed greatly increased."
As he spoke, Hardware once again turned his attention to Su Xin, who had done the experiment.
Su Xin nodded and said: "The number of successfully processed grenade fragments has doubled, to about thirty pieces, and the killing radius has also increased to more than five meters. Although it is still not as good as the Japanese grenades, the quality has improved exponentially. The problem is...
"
Zhang Wanhe sighed: "Hand grenades are a large-scale equipment of our army. Many soldiers have no guns or submunitions, but only carry a few grenades with them. Our arsenal's annual output is more than 200,000.
There won’t be any big problems in making toughened grenades. Just add a few more furnaces and more manpower. But if each one has to be grooved on the machine..."
There is no need to say more about what follows.
This is an almost impossible task.
Otherwise, based on a 70% scrap rate, the annual output of more than 200,000 grenades would be immediately reduced to 60,000, and this does not take into account the problem of insufficient machinery.
Originally, the hand grenades produced in the border area were not enough for the soldiers, and Li Yunlong had to grind them like treasures. Now if the output drops again and again, it will not be enough to equip the troops.
After thinking for a while, Wang Xuexin asked: "How about we try to cast grooves during casting?"
When Su Xin heard what Wang Xuexin said, she secretly praised her. This little Northeastern man is indeed an extraordinary person.
If there are difficulties in turning, then cast the groove directly during casting, which is convenient and can achieve similar results.
This was also Su Xin's idea, but she thought of it only a few days later, but Wang Xuexin just thought of it as soon as he heard the report and looked at the data.
Unfortunately……
"We have tried this method." Su Xin replied helplessly: "If the groove is cast during casting, the groove will be too weak. When it is toughened and burned in the furnace, the groove will be easily burned through.
, the result is that there are holes everywhere and even fall apart.”
Wang Xuexin couldn't help but feel a headache after hearing this.
He originally thought that getting a grenade was a simple matter, but he didn't expect that there was either a problem here or a problem there, and it didn't work out no matter what.
Hardware said helplessly: "How about we get a toughened grenade? It's much easier to use than the original grenade anyway."
Zhang Wanhe glanced at Wang Xuexin and said, "If there is no other way, this is the only way!"
At this time, Wang Xuexin heard a "ding" in his mind: "It has been detected that the host needs black heart toughening technology. Do you want to purchase it?"
I go……
Wang Xuexin was shocked.
During this time, he has turned off the system prompts.
Anyway, after each meritorious deed, there was a "ding" sound, and the host was rewarded with military coins for completing some task. There was no creativity at all.
The captured military equipment included an additional 92 infantry cannon, and then the military currency skyrocketed, reaching more than three million now.
But the 92 Infantry Cannon couldn't be copied without turning on the imitation mode. The military currency was a useless number to Wang Xuexin. Later, he simply stopped looking at it, just for fun.
Unexpectedly, the system prompt that had been closed would automatically pop up now, showing some "black-hearted toughening technology".
Wang Xuexin was overjoyed. A prompt appeared in the system, which must be a technology that can solve the grenade problem.
Turn to the technical page and take a look...
Oh my god, this thing actually costs one million military coins.
Isn't this killing a pig?
The imitation grenades and shells only cost a total of 300,000 military coins, and they also come with white heart toughening technology.
Now you want one million for a black heart toughening technology?
But think about it, you can’t keep military industry coins for food. If this technology can solve the grenade problem, it is indeed worth it, so just buy it!
So I spent the money as a thought.
Later, Wang Xuexin learned that this was not the case. When he knew that the military currency could be converted into real money, he was heartbroken.
When he opened the "Black Heart Toughening Technology", Wang Xuexin almost fainted.
Isn't this the same as "White Heart Toughening Technology"?
This defrauded one million military coins?
This is too dark!
What's more, if you have this black-hearted toughening technology, why do you need the white-hearted toughening technology?
Is the system embarrassed to sell a technology twice?
But then again...the white heart toughening technology was given as a gift when you bought the shells.
And although this seems to be similar, technology is like this. If you don't know that you have to figure it out by yourself, you will never think that it can be done.
