From Propulsion City To Multiverse

In the casting area.

There are 20 kaolin crucibles, including 8 large crucibles of 50 kg level, 8 medium crucibles of 20 kg level, and 4 small crucibles of 5 kg level.

I saw the engineer pull the iron chain and hook it on the four ears of the crucible, hooking 5 large crucibles and 3 small crucibles respectively.

In these crucibles, there is ductile iron that has been smelted.

That's right, the material used to cast gun barrels in steel factories is not steel, but ductile iron.

The reason why nodular cast iron is used is because the ductile iron process in steel plants is relatively mature and can be dissolved into molten iron.

However, other medium carbon steel and low carbon steel have no way to reach the state of molten iron for the time being, and can only reach a viscous molten state, which is difficult to be used for direct casting.

What's more, the strength, toughness, and hardness of ductile iron are very close to modern steel, and it has more advantages than the indigenous steel of this era.

The gun barrels of Westerners were gradually forged with steel after 1870. As for the real casting of gun steel, it had to wait until the technology of pure oxygen electric furnace steel matured. .

Therefore, Lonza adopted the most cost-effective nodular cast iron at this time.

265 kg of crimson molten iron was quickly poured into the iron mold, and the inner core of the gun barrel iron mold is a double-layer structure, a layer of wrought iron tubes directly contacting the molten iron, and a layer of copper tubes inside.

At this time, the copper pipe is filled with cold water, and as the molten iron is poured into the iron mold, the water in the copper pipe flows rapidly through the pipes that enter and exit.

This is the water-cooling method of the inner layer of the barrel, which can increase the service life of the barrel several times.

Zheng Sen looked at the 8 cannons that had already been cast.

This is the Equal 1-75 gun I designed, with a caliber of 75 mm, a barrel length of 2.2 meters, a total weight of 420 kg, 6 rifling lines, rear loading, smokeless powder as the propellant, a maximum range of 3.5 kilometers, and a copper shell Pointed shells, shells can currently produce grenades, and the output is about 270 per month.

Regarding those mechanical structures, Zheng Sen is not surprised. After all, these are mature plans of later generations. The current level of materials in Zhoushan Iron and Steel Works is roughly equivalent to around 1800-1900.

Among them, the technology of ductile iron, although the ancient Western Han Dynasty already had relevant technology, but after the chaotic era of the Wei, Jin, Southern and Northern Dynasties,

has been lost.

Modern ductile iron technology was developed by Westerners around 1950, and its performance is very close to that of modern steel.

Therefore, it is not difficult for Longsha to directly skip the front-loading gun and enter the mature rear-loading gun.

But Zheng Sen was quite curious about one thing: Longsha, how did you carve the rifling of the Equal Cannon?

Longsha smiled and pointed to a rifling and scoring machine in the distance. It was a machine tool powered by cattle. She explained:

Although there is no way to produce high-hardness drill material through smelting, we still have another way to solve it.

As soon as the words fell, a strong electric spark shot out from Long Sha's hand.

So that's how you smelted high-hardness tungsten steel and high-manganese steel? Zheng Sen suddenly realized.

Long Sha shrugged and smiled: You are a fan of the authorities, since the Xuanbing Jin can be cooled, why can't it be smelted by electric current?

Haha...it's my fault.

In this universe with special powers, sometimes tricks can be taken.

Zheng Sen looked at two types of equal guns, one without wheels, which is mainly used for warships; the other with wheels, which is planned to be used in land warfare.

After all, the land combat-type Equal Cannon weighs only 420 kilograms, and it can be propelled by horses.

Zheng Sen thought for a while, and then ordered: Longsha, let the artillery shell production department produce two more types of grenades, a heavy grenade with a range of 1000-2000 meters, and a super-heavy grenade with a range of 300-1000 meters.

Obviously, his plan is to increase the destructive power of shells in disguise by sacrificing range.

After all, in this era, even a peerless master cannot attack an opponent from a distance of 300 meters.

The equality gun can completely enter the range of 3 kilometers from the opponent, and then start firing shells to bomb the enemy.

Zheng Sen did not believe that ordinary soldiers in this era could withstand continuous shelling.

Even if it is the strongest cold weapon force of this era, it can only bear 30% casualties at most, and it will inevitably be defeated.

The vast majority of ancient troops can generally only withstand 5% to 20% casualties. If they exceed this line, they will only end in defeat.

Equipped with grenades equipped with smokeless gunpowder, it is easy to hit these feudal troops.

Of course, Zheng Sen didn't drift away.

Because this world is not pure ancient times, but a special universe with Chinese martial arts, and artillery may not be able to kill martial arts masters.

Because the sixth sense of martial arts masters is very strong, and the reaction speed is also extremely fast, unless carpet bombing is used, or the opponent is negligent, it is possible to kill martial arts masters.

Once the Human Revolutionary Federation uses artillery on a large scale in the interior, those martial arts masters will definitely react.

As long as these guys don't have their heads in the water, they will no longer choose to fight the artillery head-on. There is a high probability that they will use night attacks, mountain sneak attacks, urban street fighting, and jungle guerrilla warfare to deal with the army of the Human Revolutionary League.

Therefore, Zheng Sen wants to strengthen the martial arts training of soldiers, and use martial arts to resist martial arts.

Fortunately, with the successful manufacture of hand generators, many secretaries have already completed the introduction of electric current propulsion in this way.

The advantage of scientific martial arts is that the more knowledge you have, the faster your strength will grow.

For example, Zheng Sen's secretary, Qin Mo, this guy's electric drive has improved by leaps and bounds in a few months, and he is now a second-rate master, and he can compete with the previous Han Gaitian.

And among the secretaries who followed Long Sha, Hao Jian, Bai Yulou, and Tang Feilin, there were also many good seedlings.

Especially Longsha's secretary, because of his access to a lot of technical materials and practical work, his cultivation of scientific martial arts has become stronger and stronger.

Among them, Qiao Jianjia, the technical director of Zhoushan Chemical Company, is the most powerful. This female secretary combines chemistry and electric current to form her own scientific martial art - electric field transformation.

His face was covered with sulfuric acid in one hand, and he used it superbly. His strength was the first among the five giants in the Governor's Mansion.

With the popularization of basic education, there will be more and more martial arts masters owned by the Human Revolutionary League. By then, those traditional martial arts masters will become less and less a threat to the Human Revolutionary League.

A single master is not what Zheng Sen wants, nor does it conform to the values ​​of the Human Revolutionary Union.

As for whether scientific martial arts will be learned by traditional martial arts masters, Zheng Sen is not worried about it.

Because he, Long Sha and others have recently compiled the core textbook of the Human Revolutionary Union-Kedaoge Wulu.

This set of books has a total of 12 volumes, which are Foundation Building, Materialism, Datong, Mathematics, Nature, Astronomy, Physics, Chemistry, Biology, Jingshi, Martial Arts, and Tianwen.

As long as you learn these 12 volumes of Ke Dao Ge Wu Lu and master them well, the realm of the great master will naturally come naturally.

But Ke Dao is no less difficult to learn for the strong in traditional martial arts than Longevity Jue.

Traditional martial arts pay attention to beliefs, and many people's beliefs are often placed in gods, Buddhas, immortals, and demons.

To practice scientific martial arts, the first hurdle is materialism, and one must become an atheist, otherwise it will be difficult to move forward.

For example, Ning Daoqi, even if he read the Kedoge Wulu, he would probably end up vomiting blood.

On the contrary, Song Que, who practiced pure martial arts, might change to the scientific way.

It's just that for the great masters, they are all proud. If they change the science path, the consequences may lead to a mental breakdown.
