The ASCHS was drawn, but it was not easy to manufacture and even mass-produce.

Because this Aegis ship has almost all the top technology of the Ming Dynasty, its internal and external structures are extremely complex, and its materials are more than twice that of the Dragon Tooth Battleship.

In order to build the ASCHS, a brand new dock was even necessary, and the structure of the waterway was completely different from the past.

Because the ASCHS ship's own weight after being covered with iron armor is quite amazing, the draft depth is definitely not comparable to that of ordinary ships. If the waterway is not dug a little deeper, it may be covered with iron armor and will hit the bottom.

Moreover, its external structure is different from all previous warships. The original platform built is simply unusable, and a new platform needs to be redesigned and built.

All these Taichang were left to Wang Zheng and his disciples to work, because he also needed to prepare a lot of things for the mass production of the ASCH.

For example, the production and processing of boards requires the construction of a super factory.

It's okay to add a grid to the south of Haihe River. Anyway, it's very good here, and they haven't used one-tenth of it yet.

However, the machine tools and materials for processing boards are a bit troublesome, because the machine tools and materials required by the board processing factory are huge.

You should know that the ASCHS are seventeen or eighteen feet long and four or five feet wide, and the iron plates they have made are only two feet square at this moment, and they have to be made into double-layer Xuanwu shields.

Calculate this way, the number of boards required is quite terrifying

Each of these machine tools such as plate pressing machines, shearing machines, punching machines, drilling machines, etc. must be equipped with dozens of units, otherwise the ASCHS would not be able to mass-produce.

He can also leave this bed to Bi Maokang for the responsibility of the Ministry of Works to make the work.

As for the materials, he had to raise them himself, or organize mining and smelting, because there was too much pig iron needed to build the ASCH.

How much pig iron does an ASCH ship cover with Xuanwu armor require?

Originally, Yuan Keli said that the Dragon Teeth Warship had a minimum capacity of 500,000 kilograms of seed loading, which means that there is no problem with the 500,000 kilograms of iron armor on the ASCHS.

Wang Zheng and the others estimated that although the pig iron required for an ASCH ship was not as exaggerated as 500,000 and 600,000 kilograms, 340,000 kilograms were still needed.

Speaking of this pig iron, it is really a headache.

The Ming Dynasty was originally not short of pig iron, because during the Hongwu Dynasty, the Ming Dynasty's pig iron production reached more than 90 million kilograms, which was more than the combined pig iron production in all other countries in the world at that time.

However, his father, Wanli, was a loser, and he sent a fishing place to kill bones and marrow everywhere. The mine owners who knocked on the mine did not dare to go to mining.

Therefore, the output of various mineral deposits in the Ming Dynasty during the Wanli period was a cliff-like plunge, and the iron ore fell particularly tragically.

Historically, by the end of Wanli, the mining and smelting of the Ming Dynasty had basically stagnated, and the annual output had fallen below one million kilograms, which was directly plummeting by nearly 99% compared with the Hongwu Dynasty!

When the Chongzhen period was over, the Ming Dynasty even had to import Japanese swords to Japan.

In other words, at that time, the production of pig iron in the Ming Dynasty was not as good as that of a small Japan!

After he took power, although the mining and smelting of various minerals gradually recovered, his focus in the past few years was on copper mines and coal mines, and all the pig iron production in the Ming Dynasty did not recover very quickly.

So, what is the output of pig iron in the Ming Dynasty at this moment?

In the Wenhua Hall, a group of officials from the Ministry of Works sat on both sides, while Taichang sat on his hands and frowned and looked at the account book in front of him.

At this time, the Ming Dynasty's pig iron production has recovered to about 10 million kilograms a year. However, the Ministry of Industry organized subcontracting, mining and smelting according to needs.

In other words, they produce as much as they want, and there is no surplus of pig iron at this moment.

At this moment, the commerce in Nanzhili has developed unprecedentedly, and various handicraft workshops are springing out like mushrooms after a rain, and the demand for pig iron is already surprisingly high.

Eighty percent of the pig iron that was about 10 million kilograms of this year were consumed by Nanzhili, while the remaining 20 percent was consumed by other provinces, and almost all was consumed by Wubei City.

As for surplus, there is basically no.

Taichang looked through for a while, couldn't help but sigh slightly, and then slowly closed the account book.

Don’t you know that the demand for pig iron will explode with the development of production technology?

He slowly glanced around, then said helplessly to Song Yingxing: "Chang Geng, have you ever thought about how much pig iron you need to make rails and carriages after your steam locomotive is developed?"

Uh, this one.

Song Yingxing said a little ashamed: "Your Majesty, I am full of the high-hardness alloy you mentioned, and I didn't think about anything else."

Alas, there is still a shortage of people.

Now there are only a few real scientific and technological talents in the Ming Dynasty. Each of them has a lot of things, and they will inevitably lose sight of one thing.

It seems that the imperial examination system has to be changed. We cannot just select liberal arts talents, nor can we let all scholars learn from the liberal arts.

He must find a way to make a large number of scholars study technology or study science.

Otherwise, the later the Ming Dynasty will be, the lack of technical talents will be. In a few years, it will probably not be enough to split these people apart!

Thinking of this, Taichang couldn't help but sigh again.

There is no way, there is no one now, and he can only say helplessly: "Okay, you have too many things to be busy with, and you can't blame you for this. However, in the future, the demand for pig iron is not ordinary. We have to find a way to increase the production of pig iron. Is there any iron ore near the capital? The ASCHS is about to start construction, and we have to mine and smelify pig iron as soon as possible."

I'm not very clear about this question!

Song Yingxing couldn't help but look at Bi Maokang, the Minister of Works, who was beside him.

Bi Maokang quickly introduced: "Emperor, there are actually many iron ore near the capital, such as Jizhou, Luanzhou, Qian'an, Zunhua, Funing, Miyun, Huairou and other places. A little farther away, there is a more famous iron ore gathering place between Haizhouwei and Liaoyang in Liaodong. The iron ore there is even exposed, and there is no need to dig the mine cave at all, just dig it directly."

There are so many iron ore, so dig it quickly!

Taichang said without hesitation: "Since there are so many iron ore near the capital, there is no need to consider it. Organize manpower to mine and smelter immediately. You can ask the people below to plan carefully. In the future, the annual pig iron production will increase by at least 10 million kilograms."

ah!

Although the content of this iron ore is much higher than that of copper ore, mining and smelting are not ordinary troublesome.

A ten million kilograms of pig iron must be digged at least 20 million kilograms of iron ore to smel out. Moreover, the coal consumed by smelting pig iron is not ordinary, and 10 million kilograms are probably not enough.

In this way, the output of 10 million kilograms must be increased every year!

Bi Maokang made a rough estimate and couldn't help but say shocked: "Master, it may be difficult to increase the output of 10 million kilograms a year!"

Is it difficult?

Taichang said lightly: "You said, what's the difficulty?"

Bi Maokang calculated with his finger: "There are too many people required to mine and smelter iron ore. At least tens of thousands of people need to be organized to mine with an annual output of 10 million kilograms of pig iron. Smelting also requires tens of thousands of people. There are also a large number of people carrying ore, coal and even pig iron. There are also a large number of workshops and shops in the capital now, and there are not so many idle young and strong laborers nearby!"

What's the difficulty?

Taichang said without thinking: "I have said that you should be bolder and go to other places to recruit without anyone else. Aren't Henan and Shanxi a lot of young and strong people? They will rebel if they have no food to eat. How good they can recruit them to work, and they can make money for food. We don't have to worry about them gathering to rebel."

Uh, this, OK.

The reason why Bi Maokang didn't expect this was because he was imprisoned by his original thinking.

You should know that before the Ming Dynasty, they tried their best to limit the movement of population. The common people even left their hometowns and went to the county government to find the county magistrate to apply for road quotations.

If others don’t agree, you don’t even want to go far.

In this context, who would think of going to other places to recruit tens of thousands or even hundreds of thousands of people to work?

However, with the continuous development of the Ming Dynasty, large-scale movement of people was inevitable. Taichang even wanted to migrate coastal fishermen to the Southeast Asian region on a large scale to seize the colony!

Lu Yin had long been abolished, but these court officials had not realized that people could move on a large scale.
