Zhu Zhanji observed for a quarter of an hour and mainly found two problems, one is that four groups of people work together, but because the forging hammers are not up and down at the same time, they have an impact on each other.

It is not visible for a short time, but when the working hours are long, the staff is affected by the group next to them, and there may be danger.

This problem is easy to solve, and it is only necessary to add a partition between the hammers to solve the problem, or arrange the personnel to stand in opposite directions, so that the impact will be smaller.

The second is to replace the process of Qian Fan, which must be improved. The weight of the hammer is 80 kilograms, and with the inertia from a height of one meter, it can have a force of several hundred kilograms. And it's iron up and down, and if something goes wrong, even if you don't die, you're crippled.

Therefore, designing a process to replace Qian Fan can make people feel at ease, because if something happens, it will not only affect morale, but also delay work.

This process is actually very simple, you only need to raise the money fan from the side, design a sliding card slot for the money fan, and don't take it from the top with your hands, but push and pull it from the side.

Zhu Zhanji made a request, and the craftsmen quickly understood and could solve these two problems within a few days.

Now that these two problems have been solved, the next step is naturally to prepare raw materials and open a bank.

There is no government-run bank, and I am afraid that the raw materials will not be able to supply the production at all by relying on the annual tax silver.

The smelting of silver is much easier than that of steel, because the melting point of silver is only a little more than 900 degrees, and it can be smelted in ordinary furnaces.

However, it is only necessary to make a casting mold from a steel plate, and the silver plate suitable for forging can be continuously produced.

The key is still the raw materials, not to mention the more, without the reserve of millions of silver coins, it is impossible to promote silver coins on a large scale.

But now is the time when the green and yellow are not harvested, and it will take some time for the autumn tax silver to be collected, so there is not much silver in the imperial court.

Zhu Zhanji doesn't have much silver now.

His silver was given to Zhu Di last year, and some of it was recovered during the Chinese New Year, and it was invested in the construction of the Xiama Bridge.

He could only hope that the fleets going to Dongying and Korea would come back around November, and they would bring back enough silver.

Therefore, the large-scale promotion of silver coins will not be until around the New Year at the earliest.

Prior to this, silver coins could be promoted on a small scale in terms of the money issued by the government.

It is expected that it will take two years to make the transition, and it will be the year after that, or later, that the order will be made to sever the loose silver trade and switch to the silver coin trade entirely.

In this way, it will be possible to remove the fire consumption that the people hate.

However, it depends on whether the silver village of the imperial court can be opened smoothly.

This era is not the era when the national credit has been established in later generations, and people believe more in the state and the government.

Now is the era of imperial power, and the emperor seems to be high, but in fact, when it comes to interests, he is like a plague god, and no one wants to provoke him.

Why? It's simple, because there's no sense of security!

The emperor can do whatever he wants, say that he will copy your house and copy it, and kill your people if he kills it, and let you put your money here with the emperor, who would dare!

However, Zhu Zhanji will never allow private individuals to open a bank, even if there are many private silver buildings now, and they also do some money bank business, but this is only for now, and the money bank business in the future can only be done by the internal supervisor or the household department.

Allowing private capital to control the flow of money in the country will ultimately lead to only one consequence, and that is the instability of imperial power.

If Zhu Zhanji is not a grandson, but an ordinary person, then of course he hopes to realize democracy as soon as possible, or to take power by himself.

But he is now the biggest vested interest, how can he come to dig his own corner!

Therefore, the money bank can only be opened by itself, and in the future, private silver buildings must not be opened across borders, let alone become chains.

In this way, even local transactions can still pass through the silver building, but cross-state transactions can only go through the money bank of the imperial court.

Like the Jin merchants who pit the entire Ming Dynasty in the future, it is absolutely impossible to allow them to develop again.

Controlling finance is equivalent to controlling the stability of the entire country, and as the future emperor, he will carry out the financial monopoly to the end.

As for economic development, it has nothing to do with financial monopoly, and it is impossible to develop into the electronic age of the future. In addition to the agricultural economy, the main thing in Daming is the real economy, and the tertiary industry is out of reach.

To give a simple example, it's like the tourism economy. In later generations, there are high-speed railways, airplanes, automobiles, trains, and a perfect supporting system, so that tourism can develop.

Nowadays, people go out by walking, and the vast majority of people have never even been out of the county in their lives. Especially women, they may not even go fifty miles away from home in their lifetime, if you develop tourism, who will go!

And the imperial court controls finance well, as long as there is a corresponding and perfect industrial development support plan, even if the development is slow, it is definitely better than finance that everyone can use and chaos.

In his previous life, he controlled and participated in several world-class banks, and Zhu Zhanji was clear about the role that banks could play in industrial development.

Whoever wants to play tricks with him in this regard is really a hatchet, and he has to kill chickens and monkeys.

Officials use silver coins, silver coins for project settlement, silver coins for trade transactions, and then there are cards between the states and counties of the Ming Dynasty, and a large amount of cash silver can not be circulated, and it will not take long for the circulation of silver coins to develop.

At that time, the Ming Dynasty would be much more stable than it is now.

After explaining these problems, Zhu Zhanji took a box of silver coins and prepared to leave.

As for the safety precautions here, including how to prevent craftsmen from stealing silver without permission, the silver bureau has very complete regulations, and he doesn't need to worry about it at all.

As soon as he left the compound, Zhu Zhanji saw Ma Zhicai guarding the door, and when he saw Zhu Zhanji coming out, Ma Zhicai immediately held up a half-meter-long steel pipe in his hand and said, "Your Highness, please take a look at this gun barrel ......"

Zhu Zhanji jumped off the horse, took the steel pipe, and put it in front of him.

This is not a steel pipe wrapped in iron sheets by today's craftsmen, but an iron rod with fine holes, drilled with a drill bit.

The iron rod is made by pouring semi-melted molten iron into a pre-made steel model. In the center of the steel fan, there is an iron wire made of refractory clay.

Solid iron rods are really difficult to drill, so this method can only be used to leave a hole between the iron rods.

The wire is wrapped in refractory clay to keep a straight line, and after the iron rod is formed, the refractory clay is mashed to extract the wire, leaving a small hole.

Nowadays, the Ministry of Industry not only uses manganese steel to make Qian Fan, but also uses manganese steel to make drill bits. The drill bit is polished little by little by craftsmen, and then heated and quenched several times to increase the hardness of the drill bit.

Starting with a small hole, the hole diameter was enlarged with a fine drill bit, and after three drill expansions, the current style was formed.

Now there is no capacity to produce seamless steel pipes, and it is only possible to rely on this local method to get a suitable barrel.

After listening to Ma Zhicai's introduction of the processing procedure, Zhu Zhanji thought about it, and there was no better way to improve. He just asked, "How long can you drill out of the barrel now?" ”

"Drill from two ends separately, and you can only get a barrel of one foot and eight inches, but the drill bit is too long, and the shaking will be more severe, which will affect the size of the barrel."

"It's still a little short. The barrels used in today's Shenji camp are all four feet long, and such barrels can only be made into short guns. He thought for a moment and said, "Make a few strong barrels, and let the craftsman make me a few short guns." Single-tube, double-tube, including three-eyed guns, make me a handful. ”

Although the role of the short gun on the battlefield is not very large, it is still very good as a weapon for self-defense. In the future, if their own guards are all equipped with this kind of short guns, they will have twice as many people attacking, and they will not be their opponents.

After Ma Zhicai responded, Zhu Zhanji asked again: "How is the spring machine and gunpowder cap I said last time?" ”

Ma Zhicai shook his head with some distress and said, "It is still very difficult to meet His Highness's requirements. Now it is only the return of the spring machine that has been solved, but how to automatically ignite to the chamber of the gun, and it does not leak, stumped everyone. ”

Zhu Zhanji had seen the brown bass with his own eyes, but he did not pay attention to the design of the ignition cap at that time, nor did he pay attention to the air-holding device of the chamber. So although he knew that the flintlock pistol would definitely replace the arquebus, he couldn't give the slightest suggestion on how to do it.

However, when he was about to leave, he suddenly remembered something. He picked up the steel pipe and looked at it again and said, "Since it is difficult to drill longer with a drill bit, have you ever thought about using a grinding stone?" ”

Ma Zhicai paused for a moment and asked, "How can the grinding stone work?" It's too brittle to drill at all......"

Zhu Zhanji said with a smile: "You have people grind the grinding stone, and then glue it to a thin iron rod to make it round, slightly thinner than the barrel of the gun." Now, after drilling through the iron rod with a fine drill bit, the barrel is sharpened out with a grinding stone. Such a grinding stone rod can be four feet long, and no matter how long the barrel is, it can be sharpened, right? ”

Ma Zhicai was like drinking Daigo, patted his thigh and said: "Look at my pig's head, His Highness's meaning is the same as making a pencil, and a grinding stone is easier to make than a pencil." I immediately arranged for someone to try to make ......"

Zhu Zhanji smiled, although this would be a waste of grinding stones, but at the very least, it could solve the problem of drilling.

As long as the refractory soil in the middle of the iron rod is made coarse, when the time comes, drill it once with a fine drill bit, and then use a grinding stone rod to grind it slowly. Now with a machine tool, it's easier to build a barrel by hand than slowly.

sent Ma Zhicai away, and this time no one stopped Zhu Zhanji anymore. However, I haven't entered the city yet, and I just arrived at the Qingliangmen wooden bridge that entered the city, and the wooden bridge was blocked.

The guards of the Five Cities Soldiers and Horses Division on duty saw Zhu Zhanji riding over, and immediately knelt down in front of Zhu Zhanji in fright. "Your Highness, please wait, the little one will clear the road immediately."

There were too many people, and I didn't know what was going on, so Zhu Zhanji asked, "This is the gate to enter the city, how can it be blocked?" ”

The guard said disapprehantly: "A small country folk came to Beijing with their families, and for some reason they clamored to beat the concubine to death at the city gate, so they are all watching the lively ......."

Zhu Zhanji turned his head and said to Yang Zhangde: "Go and hold the person for me!" There are still such violent people who keep saying that they want to take people's lives! ”
