Datang: Li Shimin begged me to rebel

Changsun Wuji didn't pay attention to everyone's gaze at first, but after he noticed it, he quickly realized it, and after he realized it, Changsun Wuji was a little speechless.

This is boring, the old man has reconciled with His Highness and the like, what do you mean by looking at me like that?

"Your Majesty, Your Highness, everyone, please follow me." The factory manager led them forward again, and there was an open hearth furnace not far in front of the blast furnace.

For Datang, the open hearth furnace steelmaking may need to be used for several decades in the future, until a large number of power plants can supply the whole country, and it is estimated that the latest electric furnace will be installed at that time.

Therefore, the improvement of the open hearth furnace is nothing more than to see how much molten steel the open hearth furnace can produce in a single time. The more molten steel in a single open hearth furnace, the more difficult it is naturally.

"Your Majesty, let's go this way. The open hearth furnace needs to be checked in the safe room. It's not safe here." The factory manager led Li Ke and the others to detour around an area first.

"Not too safe?" Li Shimin frowned, "What's the danger?"

"This is an open hearth furnace with the latest technology. It is not used for heating and burning coke in traditional steelmaking, but gas, and gas is relatively risky. Although we have various safety measures, there is still a risk of explosion if it is not operated properly. .” The factory manager gave a quick introduction.

"Gas?" Li Shimin was taken aback for a moment.

"Father is the gas formed after water passes through hot coke, and then these gases can be ignited and burned." Li Ke introduced it to Li Shimin.

This gas is different from the gas in the mouths of most ordinary people in later generations. The gas in the mouths of ordinary people in later generations refers to liquefied petroleum gas.

The gas here is water gas, that is, hydrogen and carbon monoxide.

If the open hearth furnace uses solid fuel, it will cause coal ash to clog the furnace, which is very inefficient. It may need to be cleaned after two or three times, but if it is heated by gas, the problem is not so big.

Li Shimin can't understand it. It's really hard to understand this thing if you don't learn from the basics.

But it doesn't matter, just know it.

"This open hearth furnace is the largest open hearth furnace we have ever manufactured. At present, it can tap about 3 tons of steel at a time." The factory manager introduced it to everyone.

Now everyone is completely speechless, fine steel, 3 tons at a time?How was the fine steel forged before Datang?They are all forged by artisans bit by bit, not to mention efficiency, efficiency has nothing to do with that.

Otherwise, why would there be such a thing as refined steel?

But now... 3 tons can be refined in one furnace?That is 6000 catties of fine steel!

"How long will this one furnace take?" Li Shimin asked after taking a deep breath.

"The steelmaking speed of this open hearth furnace is faster, because it is connected with the blast furnace next to it. The molten iron just out of the furnace can be directly entered into the open hearth furnace after it solidifies slightly. When the molten iron enters the furnace, its temperature is still very high, so it can be consumed Less fuel can be melted. This can be refined in about an hour."

"But because of the blast furnace output problem, if cold material is added, it takes about 3 hours for a furnace because of the preheating problem."

Everyone didn't know what to say. I don't know why they suddenly felt that making steel was easier than making iron?

As per 3 hours a furnace, it is no problem to practice five or six furnaces a day, right?3 tons in one furnace, 18 tons in a day, 3 jin of fine steel... Everyone was going crazy.

They finally understood why Li Ke could equip all soldiers with steel armor!

This is what they have to do if they have this!

"How is it? Dad, I developed this technology, isn't it amazing?!" Li Ke proudly showed off to Li Shimin.

"Excellent!" Li Shimin praised on the surface, but in his heart he started. Fortunately, I was still worried that you made a mistake in attacking Goguryeo, and I was going to give it to you in the Zen seat after the Great Tang Dynasty was peaceful.

That's it... Fuck you, when I go back to find a good opportunity, I will find a way to throw this position to you, and then I will take your mother, stepmother, concubine and the others to play in the mountains and rivers.

When the time comes, the Taiji Palace will belong to you. I want the Qinwangzhuang, but your future wife will say that the Taiji Palace will belong to the Tang court, which is very good!You can do it yourself, half of the Daming Palace is built, and you can do the rest yourself, I don't care.

As the emperor of the Tang Dynasty, you can't spend money casually, right?Because the consumption of the emperor of the Tang Dynasty was paid out of the treasury, only for daily life.

Go enjoy this yourself.

I go out to play by myself and spend whatever I want.

I'm worrying about you for nothing, huh, can you overturn the car just like this?Li Shimin knew where Li Ke's confidence came from.

If he had known this earlier, he would have confidence.

But now, looking at Li Ke who was complacent there, Li Shimin was suddenly in a good mood, stretched out his hand and patted Li Ke on the shoulder and said: "Sanlang has done a good job, work hard, and have a good rest recently. There is Father Emperor inside, don’t worry about it!”

Li Ke was stunned for a moment, the sun came up from the east today?Didn't my father always think that as a prince, if he is capable, he should work harder for Datang?What's wrong today?

Is it too happy to see these things in the industrial area, so I give myself a vacation?

If I knew this, I should have brought Lao Li over to have a look.

Then...how about showing Li Shimin the various enterprises in the industrial zone separately?

Wouldn't it be great to be happy every once in a while and take a complete rest?

"Thank you, Father." Although there were all kinds of coquettish operations in his mind, Li Ke naturally agreed quickly on the surface. What if Lao Li regretted it for a while?

Lao Li is very good at regretting.

After introducing the iron and steel factory, Li Shimin and the others watched a brand new batch of molten steel come out of the furnace. They watched the crimson molten steel flow out along the unique groove, and then quickly formed a fixed pattern. Pressed into special, elongated steel bars.

All of this is done through a complete process. Although some workers are required to operate in the middle, those huge steam engines operate the horrible cast iron blocks to directly extrude the red steel blocks, which still gave them a great shock!

Because this is an achievement that manpower will never be able to achieve!

But again, this is indeed the most direct expression of human wisdom!

Human power is limited, but human wisdom is unlimited.

"Are you going to demolish such a big steel factory?" Li Shimin was still a little uneasy.

"Of course, Your Majesty, the ultimate goal His Highness gave us is that the iron-making blast furnace should reach about 5000 tons of iron at a time! And there is no such a large place near Chang'an, not to mention, because of the Weihe River and other reasons, it is not very convenient to transport, and there is Some of the previous designs are outdated."

5000 tons? !Everyone is stunned, do you know what you are talking about?

One furnace of iron needs to smelt 1000 million catties? !How much was Datang's annual steel output at that time? !
