Daming: I asked you to hang yourself, but I didn’t ask you to rebuild the Ming Dynasty

Zhu Youjian turned his head and looked at the old man with age spots on his face, his eyebrows curved.

"Old Qing's family, is there any problem with this thing?"

After returning from Pengjia Town, Zhu Youjian showed a sincere smile for the first time.

"No problem, no problem!"

Bi Maokang rubbed his hands and smiled:

"This thing is the same as water cones and water mills. His Majesty's thinking has opened up our previous blind spots in thinking.

The components that can be connected and separated are beyond the veteran's expectations. "

Bi Maoliang also came closer, leaving only a facade and a severely sunken mouth.

"Your Majesty, we have experimented. As long as the rough embryos are sent here, and after being stamped and forged with this thing continuously, it can be used as a steelmaking machine!"

Zhu Youjian laughed.

Bi Maokang on the other side pushed his eldest brother Bi Maoliang away and said dissatisfied:

"Brother, are you confused?

Isn't steel-making just the fine steel that is formed after continuous beating to remove impurities?

We use this hydraulic press to forge, and the blacksmith uses a hammer to forge, isn't it the same essence?

The things created are naturally the same! "

"Where is it the same?"

Bi Maoliang frowned, trying to push his old brother away. Who knows, but he was ten years older and couldn't push this "great guy" away.

Bi Maoliang had no choice but to stand on the other side, tilted his neck and shouted:

"Can it be the same? It takes ten kilograms of pig iron to produce six kilograms of steel!

Why are the iron cannons made by the capital easy to explode? Do you think they don't know how to use forged steel?

It’s not because there are too many manpower and the manufacturing cost is high!

It’s not that they don’t have the technology, but the cost is too high!

Your Majesty gives us this hydraulic machine to cast an artillery piece, which can save a thousand manpower!

It can save a thousand labors!

Can this be the same? "

"The craftsmen of the Capital Cannon Casting Bureau require more than 300 construction days for each cannon. What about us?

As long as we have these ten big machines and a hundred craftsmen, we can build ten doors in two days!

If we do not count machines, one cannon only requires more than 20 construction days. With the manpower they use to build one cannon, we can build hundreds of them! "

"Our quality is better, faster and requires less labor!"

"Tell me, can this be the same?"

Bi Maoliang put one hand on his hips and pointed at his younger brother with the other, blowing his beard and staring angrily, chattering incessantly:

"Xui, tell me, can this be the same? Xue!"

Bi Maokang did not spare him, and immediately retorted:

"Why is it different? Why is it different? Your Majesty was talking about the quality of the steel, and he didn't ask you about the cost. Tell me, how is it different?"

Bi Maokang also put his hand on his hips and pointed at his brother with the other hand, and resolutely fought back.

……

Seeing the two old people arguing so hard, Zhu Youjian couldn't laugh or cry.

Two lovely old men!

The scene of the two arguing seems to be very common.

Zhu Youjian was caught in a dilemma between the two of them, but the two apprentices on one side were already used to it, and they actually did their own thing without being affected.

Zhang Jimeng grabbed the bell rope hanging high on one side and knocked it a few times.

In the heating factory building with a tall chimney, someone pulled a square, red-hot iron block on a small cart made of iron and ran over quickly.

Zhang Jimeng picked up the clamp and, with the help of two craftsmen, lifted the iron block onto the stamping table.

Zhang Jimeng adjusted his position and stepped on the pedal.

"Bang!"

The head of the hydraulic machine, which was like a punch machine, fell down and hit the iron block hard, causing sparks to fly!

Zhang Jimeng slightly adjusted the angle of the iron block, and the stamping head struck again and again.

After a while, the square iron block turned into a cylindrical shape.

Zhang Jimeng released the foot lever and adjusted the position of the iron block again. After another operation, before the iron block cooled down, a cylinder one foot long and thick as a basin was ready.

Zhu You reluctantly allowed the two to quarrel and looked over carefully.

It seems that what Zhang Jimeng is building is a cannon barrel.

It's just that this thing is too short.

The deafening stamping sound perfectly stopped the quarrel between the two old men.

Zhu Youjian pointed at the workpiece Zhang Jimeng was processing and said:

"You can rush out of the inner diameter of the gun barrel directly. You only need to prepare a cylinder while..."

Zhu Youjian was about to talk about the methods of ram artillery in later generations.

Unexpectedly, Zhang Jimeng had already taken out a small cylinder, placed it in the middle of the big cylinder, and then stepped on the foot lever.

The cylinder instantly became a ring.

Zhang Jimeng picked up another long cylinder, inserted it into the inner opening, and tipped the forging.

The craftsman next to him placed two supports on the stamping table.

The three of them worked together to place the long column on the support.

Someone pushed the fiery red cylinder with a clamp and placed it under the punch.

"Bang bang bang!"

Zhang Jimeng stepped on the foot lever, and under the forging of the punch, the fiery red column continued to extend.

With each punch, Zhang Jimeng would slightly rotate the cylinder, and the stamped workpiece would become longer and longer and rounder...

After a while, a cannon barrel was formed that was two feet long, with an inner ring about as thick as a basin, and only half a finger thick...

Zhu Youjian stared blankly at the finished cannon barrel in front of him, unable to complain in his heart.

This Nima...

Is Akito so smart?

(Tomato’s parent group, Douyin, has a cannon-casting video. If you are interested, you can take a look. The process is basically the same as above.

In addition, according to the history of world artillery, artillery and musket technology reached its peak from the 200th century to the early 1860th century. It was not until around 200, [-] years later, that it began to develop rapidly again. The intervening [-] years were the period when various tactics emerged. Whether it was firearms technology or industrial technology, there were no major changes. )

Zhu Youjian was stunned...

Bi Maokang had already let go of the quarrel with his eldest brother Bi Maoliang. He shouted at the top of his voice:

"Your Majesty, this is the method that my eldest brother came up with. He said that this thing is so powerful that if you press it directly out of the chamber, it will definitely go much faster..."

At this moment, the white-haired old man seemed to have forgotten that he was quarreling with his elder brother just now, and actually took credit for his elder brother...

Bi Maoliang chuckled, and in the midst of the noise, he raised his voice and shouted in a boastful and shameless manner:

"Your Majesty, sir, how do I do this?"

Zhu Youjian silently extended his thumb...

……

Zhu Youjian followed the two gray-haired veterans and continued walking forward.

I saw a workshop in front of me responsible for forging joints.

"Our Ming Dynasty casts Hongyi cannons using the segmented tile-shaped casting method. After the various parts are cast, they are put together and forged again..."

Bi Maokang kept talking about the principles of casting.

The segmented tile-shaped casting method has existed for a long time, and can even be traced back to the period of Emperor Wuzong Zhu Houzhao.

……

After the two arrived in Guanghua, they saw Wang Lian mentioning Wu Guang several times, saying that the Wu Guang artillery had made great contributions on His Majesty's way south.

The two of them were obsessed with weapons, and they immediately became interested in the famous heartless cannon.

So, Wang Lian personally asked for a dishonest person.

After the two studied it carefully, they found that the workmanship of this thing was very rough, and the range was only about a hundred feet.

Although this thing is very powerful, the damn thing is, the impact point is so deceptive!
