The Head of the Ming Dynasty Spared His Life

In the bitter sea breeze, tens of thousands of skilled construction workers sent from Beijing New Town are busy building two cement processing plants.The cement mixing converter with a height of 10 feet has slowly stood up amidst the slogans of the strong men!

The fiery scene and the fast construction speed are staggering.

Hai Rui was also taken aback.

After all, he has presided over the construction of a new city in Beijing and knows how powerful this cement is.

Once cement is added to the city wall, it can be called a copper wall and an iron wall. Even with the most robust elite soldiers, they can't penetrate the bricks of the city wall even if they stab hard with spears!

Now, Yan Song wants to use a lot of cement in the construction of Tianjin new city and port?

Seeing that these two large-scale cement factories with eight high-temperature cement converters were being erected, Hai Rui was bewildered.

Yan Song's handwriting is really big.

Qiao Zhiyong's methods are powerful enough.

He quietly asked Qiao Zhiyong: "How could you drag those more than 1 workers from Beijing to this shitty Tianjin?"

Qiao Zhiyong smiled honestly: "If you have money, you can turn 2.5 ghosts. These 1 people are all my fellow villagers in Shanxi. I pay them wages in Beijing. One person is two cents a day. This is enough. But Mr. Yan Ge signed the contract with me to supply the amount of cement in Tianjin New City. We couldn’t finish it in two years. I simply waved my hand and gave them three cents a day! The salary for this month is 9 taels of silver! If they work for one year, they can build a cave in Shanxi and marry an aunt, who is Mizhi's aunt! Why not do it?"

Hearing that a Shanxi worker could earn 100 taels of silver a year working here, Qian Guangjin was moved and sighed: "Don't say that these Jin Laoxis who are facing the loess and their backs are willing, they are the bosses of Beijing City. Gentlemen, if you give him this price, eleven out of ten will be willing to come! The wages are too much!"

Chapter 467 More Advanced [Crucible Steelmaking Method] [5]

"My God, just for these two factories, you employ more than 1 workers, and your annual wages are over one million! Doesn't that mean that your profit is at least tens of millions?!"

"That's right, wouldn't that be several times stronger than our profit?"

The eyeballs of these business tycoons are all red.

Yan Song said indifferently: "Qiao Zhiyong's cement is necessary for the construction of my new city. The annual profit is tens of millions, why not? Shopkeeper Hu, how is your steel preparation?"

"Steel?" Hai Rui heard the new term again, and was a little crazy: "What is this?"

In his mind, isn’t it necessary to mine rocks, dig kilns and burn bricks, cut wood, and mix lime, rice soup, and eggs into a binder for the construction of a new city?

Why did Yan Song build the city with either cement or steel?

There are also many tycoons of Ming Dynasty who are also stunned.

They are also well-informed, but they have never even heard of the name of this steel. 15

Hu Xueyan stood up, saluted everyone, and said with a smile: "Everyone, Mr. Yan Ge's expectations for Tianjin Port and the new city are far higher than other places in Daming, and even exceed your best imagination! This city will become an eternal city. The city of glory that represents the glory of Ming Dynasty! More advanced building materials are indispensable."

He coughed: "I got a book [Crucible Steelmaking Method] from an overseas businessman half a year ago, and invited the most advanced iron and steelmaking craftsmen in Daming to conduct scientific and technological public relations for half a year. I have finally gained something. A few days ago, my Great Ming's [Crucible Steelmaking Method] has been formally tested successfully, and the first batch of qualified steel has been manufactured!"

"What the hell is this steel?" Hai Rui was a little crazy. He was a scholar who read sage books. Hearing about [Crucible Steelmaking Method] and cement converter was like listening to heavenly scriptures.

How did Hu Xueyan obtain the [Crucible Steelmaking Method]?

It started with Yan Song who was still on tour in the south half a year ago.

Yan Song was writing [Sea Power Theory] while thinking about how to promote the technology of Ming Dynasty to make great progress.

The so-called steel is an important weapon of a great country!

No matter whether it is to build a new port in Kaihai, or to build an ocean-going fleet in the future, to colonize the Americas, it is impossible to do without steel.

Yan Song used up to 20 system points to draw a book [Crucible Steelmaking Method]!

In fact, China is the first country in the world to produce pig iron.As early as the late Spring and Autumn period of the 6th century BC, there were pig iron objects, which was more than 2000 years earlier than Europe.During the Warring States period, there was the soft casting method, and during the Southern and Northern Dynasties, there was the iron casting method, both of which were much earlier than in Europe.

But the problem is that China's steelmaking method has a very small output and can only be used in small quantities on the blade of a weapon. This is how the so-called "good steel is used on the blade" comes into being.

In the world, the earliest steelmaking method was first applied by the Englishman Hongzman in 1742. He cut the carburized iron material into small pieces and placed them in a closed clay crucible, heated outside the crucible, and the iron material continued to absorb The carbon in the graphite is melted into high-carbon molten steel, which is cast into small ingots and then forged into the desired shape.When the steel is melted in the crucible, graphite carbon can also act as a reducing agent, oxygen in the steel can be removed, and various inclusions can also be removed from the liquid steel, so the quality of the steel is better than that of various metal materials at that time. This method of making tools for processing metal materials is called [crucible steelmaking method].

[Crucible steelmaking method] is the first method in human history to produce liquid steel.But the production volume is small and the cost is high. After the invention of the electric arc furnace steelmaking method at the end of the 19th century, it gradually took its place.

Of course, Yan Song also considered more advanced steelmaking methods such as the electric arc furnace steelmaking method in the future, but the problem is that it is unrealistic!

At this time, there is no electricity at all. Where did the electric arc furnace steelmaking method come from?

[Crucible steelmaking method] is the most realistic steelmaking method in the absence of electricity and mechanized mass production in the Ming Dynasty.

As long as there is pig iron, a closed clay crucible, and a high enough temperature, a relatively ideal yield and quality can be achieved.Although it is not comparable to the electric arc furnace steelmaking and converter steelmaking methods of later generations, it has been ahead of the world for hundreds of years!

In particular, steel is stretched into steel bars and added to the cement produced by Qiao Zhiyong to form reinforced concrete!

This is really reinforced concrete.

Yan Song wanted to laugh when he thought of the bewildered look of the future historians who came to the ancient port of Tianjin for archaeology.

They will find that the Ming Dynasty in the 16th century had reinforced concrete technology that was almost the same as modern times, and it was also widely used in the construction of new cities, making Tianjin and the port impenetrable and indestructible, and they are still rock-solid after hundreds of years of ups and downs!

Yan Song is full of bad taste of making historical jokes, and even more satisfied with running a big era.

"Your Majesty, next to Qiao Zhiyong's cement plant, two steelmaking plants have been established. Mr. Yan Ge, please take a look!"

Hu Xueyan pointed to the south of Tanggu, and sure enough, two large-scale steelmaking plants stretching for several miles were built by the sea.

He said to Yan Song with admiration: "It's Mr. Yan Ge who is far-sighted and asked me to come here half a year ago to inspect 230 pieces of factory construction. There are abundant seawater resources here, which can be used to cool high-temperature furnaces without spending a penny. And The land is flat and wide, and the land does not require money, and it does not disturb the residents. It is also easy to discharge sewage, and there is no cost.”

Yan Song knew from later generations that many steel factories were built by the sea, so Hu Xueyan asked Hu Xueyan to inspect it many times in half a year.

No, it just came in handy.
