Emperor Chongzhen of the Ming Dynasty

Chapter 373 The Current Situation of Ming Dynasty Firearms Manufacturing (No.14)
Now the efficiency of large-scale production of crossbows and cold weapons in Ming Dynasty is four or five times that of before, which is due to the improvement of production technology brought about by the advancement of steelmaking technology.

Although the guns are still manufactured by hammering and adding molds, due to the assembly line production and the improvement of metal materials, Daming's guns still rank first in the world, completely surpassing the current Manchu Qing.

In addition, there is another technology that is even more impressive than the world, which is the continuous improvement of the firing device of the flintlock.

Bi Maokang is now specializing in this area.

Now the best main battle musket in Ming Dynasty has progressed from the Chongzhen [-]-style flintlock gun to the Chongzhen [-]-style flintlock gun.

The biggest difference of the Chongzhen [-]-style flintlock gun is the improvement of the material and shape of the barrel. The hexagonal shape makes the barrel already have a simple or early similar product of the rifled gun.

This undoubtedly means that the rate of fire, range, and even accuracy of the Chongzhen [-]-style flintlock gun are stronger than those of the Chongzhen [-]-style, and it is no longer a problem to effectively shoot and kill the enemy within [-] steps.

But what Zhu Youjian didn't expect was that Bi Maokang had already designed another new gun.

Moreover, this new gun can be said to be a real epoch-making killer in the field of Ming Dynasty flintlock gun manufacturing!
Because this new musket has not been improved into a rifled gun.

(Why is it not described in the previous chapter, so I won’t repeat it here)

But this new musket has made great improvements in loading, because it is a breech-loading gun, that is, two rounds of balls are installed at the rear end of the firearm.

This kind of firearm was originally invented by a man named Dai Zi during the Kangxi period of the Manchu Qing Dynasty.

Now, under Zhu Youjian's suggestion, Bi Maokang directly made it available in advance.

"As His Majesty mentioned, there are two rounds of continual bullets inside, a total of 28 bullets. When the first trigger is pulled, the gunpowder and lead bullets will automatically fall into the barrel;
The second wheel then turns, and the flint is struck to fire;

After the first round, you can play the second round;
This saves the loading time and improves the loading efficiency, and the burst capability is greatly enhanced, and on the basis of the Chongzhen [-]th Type, it can make its range and accuracy higher, plus the three-point line required by His Majesty Aiming and shooting can also improve the user's shooting accuracy. "

After Bi Maokang said this, Zhu Youjian nodded: "When will this be put into production?"

"It is expected to be in January next year. It is still in the experimental stage. Some parts have not yet been standardized, and there is no way to implement grinding machine processing. Some precision parts need to be polished by skilled craftsmen. However, this gun is indeed much better than the Chongzhen [-]th Type. What Weichen means is to speed up the production progress while concentrating and training more skilled craftsmen to create a batch of non-absolutely standardized trials for this battlefield;
Actual combat is also the best way to test firearms. If the Chongzhen [-]th Type had not been put into war shortly after its development and production, we would not have been able to improve the Chongzhen [-]th Type so early. "

Zhu Youjian agreed with Bi Maokang's opinion, so he asked Bi Maokang to build a batch to equip a scale of one thousand people.

"This gun will be named the Chongzhen 21-type flintlock gun at that time, so is there any other improvement that can be made, such as whether the firing device can also be improved;

The current firing method is to use the flint to generate sparks to ignite the gunpowder, but many times the flint will fail or the strength is not enough, so it needs to be hit several times, which delays the shooting time. This is very fatal on the battlefield, and the cost of flint is too high. ;

We can find out if there is any flammable material that can replace the flint to ignite the gunpowder, such as paper or something better, and directly ignite the gunpowder by hammering. "

Zhu Youjian was talking about firing a gun, but Bi Maokang was a little confused:

"Your Majesty, I understand what your Majesty means, but the kind of gun paper your Majesty said is not very good, it is easy to get wet. I have a lot of rain in the south of Ming Dynasty and now the weather is cold and cold. I am wondering if there is any better material. I will try it these days." There are a lot of things like oilcloth, but in the end there is no substitute for flint."

"This requires you to create the material yourself. I remember that there is a material that can be used. This is called mercury fulminate. If you apply it to a copper plate as a hammer, and then hit it with a sharp structure, it will directly ignite the gunpowder. Mercury is mercury fulminate, mercury, presumably Ai Qing already knows what it is, as for fulminate, it may be difficult for you, after this war is over, I will personally help you how to extract fulminate and make mercury fulminate."

This can only be taught by Zhu Youjian himself when the time comes, and Zhu Youjian himself has to remember it well.

Daming is now able to produce some natural products and rough processed products such as alum, green alum, fire salt, salt, sulfur, quicklime, trona, ferrochrome, mercury, plant ash, etc.

But for Daming, mercury fulminate still needs further breakthroughs in experimental technology.

It may not be too difficult for modern times, but for the era of Ming Dynasty, people don't even know what fulminant is.

But it is not impossible to realize the possibility.

Because at first the easiest way is to use the silver mirror reaction.

The silver mirror reaction will produce fulminic acid as an organic acid after a long time, and then react with mercuric oxide to produce mercury fulminate. The silver mirror reaction uses silver nitrate and aldehyde group to reduce the reaction to produce silver. This experiment is not difficult. Zhu It can be operated by inspection.

Daming can now use sulfuric acid and fire nitric acid to produce nitric acid, and it is not difficult to produce silver nitrate.

Aldehyde groups can be found in glucose, and glucose is a monosaccharide. Most of the sugars in our life are polysaccharides. Of course, it is not without glucose. For example, it is also found in blood and some fruit juices, but the amount is too small.

To obtain glucose on a large scale from an industrial point of view, a certain concentration of dilute hydrochloric acid is needed to extract it from starch, which naturally comes from foods such as potatoes.

However, Zhu Youjian does not plan to use the silver mirror reaction to produce fulminic acid.

Because he didn't know how much fulminic acid the silver mirror could produce for a long time.

He decided to use another method, that is, the reaction of silver nitrate and saturated ethanol solution to obtain fulminate and then react with mercury oxide to produce mercury fulminate. Ethanol is not difficult.

But now Zhu Youjian has to teach Bi Maokang and other Ming people how to prepare the solution.

After all, whether using the silver mirror reaction or ethanol, a solution is required, and this is actually the chemistry knowledge in middle school, but Bi Maokang and others don't know, they may not know the difference between a solution and a suspension at all.

Because Song Yingxing was in charge of the Iron and Steel Smelting Bureau to manufacture alloy steel, he used high-temperature calcination of natural compounds to obtain alloy steel technology like a big wave washing sand.

And Zhu Youjian hopes that Bi Maokang can master the use of chemical reactions to extract and manufacture the compounds he needs. Perhaps mercury fulminate is just the beginning.

Speaking of mercury fulminate, I have to admit that it is a highly toxic substance.

Zhu Youjian didn't plan to touch it by himself, he felt that he had to find a Western fan to operate it and guide him from the side.

Once the Mercury Fulminate can be crafted, the Percussion Gun can be crafted.

In addition, Daming now has the technology of breech-loading guns. If it breaks through the manufacturing of rifling in the future, it can produce breech-loading rifles. At that time, Daming may really be invincible in the world.

Zhu Youjian began to fantasize.

But in fact, relying on the current firearms industry of Ming Dynasty, it is already invincible in the world.

This is only technical production, and there is a complete set of industrial systems in Ming Dynasty. Zhu Youjian still continues to inspect his military base.
