The coke from the Kongshan coking plant was directly transported to the newly built steelmaking plant in Kongshan without stopping for long.

If Zhu Gaoxian wants to establish an industrial city in Kongshan, the link of steel mills must be indispensable.

In ancient steelmaking, the ore with high iron content was mined first, and then the ore was heated by charcoal burned in the furnace, and the heated ore was then thrown into cold water, the purpose of which was to make the hard ore brittle after thermal expansion and contraction, and then the ore that had been treated in this way was crushed, and then the iron part was left behind by water washing, and the iron sand was put into the earthen steelmaking furnace to be heated and melted, and the molten molten steel was cooled.

The steelmaking technology of the Ming Dynasty was quite mature and advanced, and it was far ahead in the world. Even Britain, which was the first to carry out the Industrial Revolution, only caught up with the steel production of the Ming Dynasty in the 19th century.

The biggest disadvantage of the Ming Dynasty's steelmaking technology is that the temperature is not enough, because the temperature is not enough, the smelted steel is only paste, not liquid. If you want to refine liquid molten steel, you have to reach at least more than 1,600 degrees, but more than 1,300 degrees of steelmaking in the Ming Dynasty is already the limit.

The biggest reason for this problem is because the Ming Dynasty used charcoal for iron smelting, but Zhu Gaoxian had coke, so he didn't need to worry about the lack of temperature.

Unlike traditional steelmaking, Zhu Gaoxian uses blast furnace steelmaking.

This method is relatively simple, with high output and low labor requirements.

In addition, adding a small amount of alkali while smelting by this method can also solve the problem of dephosphorization. The disadvantage of Kongshan's steelmaking plant is that the smelting time is long, each furnace takes about one day, but because of the large melting pool, each furnace can produce 2,000 catties of molten steel, the output is extremely high, and the quality is also high.

After the molten iron is melted in the steelmaking furnace like magma, the ore can be added for refining when the molten pool is heated to the specified temperature, and the alkalinity of the slag can be increased at the same time.

After the process, the uneven layers of brown iron ore become bright, high-quality steel. However, there will be a special trolley to pull the steel away and transport it to the warehouse.

……

In the palace of King Qi, Zhu Gaoxian was giving instructions to his little secretary Su Wu: "In terms of iron ore procurement, we must urge it, after the operation of the Kongshan Steelmaking Plant has achieved very good results, I plan to continue to expand." ”

Su Wu was a little confused: "Lord Wang, two new steel-making warehouses in Kongshan have been built, but the two newly built ones are almost full, we have refined so many high-quality steel materials, can we just put them in the warehouse and look at them?" ”

Zhu Gaoxian shook his head and chuckled: "Don't worry, someone will come to buy it." ”

"Who buys such a huge amount of steel." Su Wu was a little tired, "If we can't find a stable export, our series of steelmaking lines in Kongshan are afraid that they will go bankrupt." ”

Zhu Gaoxian made steel neither for his own use nor for sale, and such a huge amount of steel could only be used for forging weapons. But steelmaking and forging weapons are two different things, Zhu Gaoxian smelted out the steel and put it in the warehouse and hoarded it no one cared about him, he dug coal in Kongshan This is the emperor's order, and how to use the coal dug out, this is the matter of the Qi Palace, the emperor has been watching, but he didn't speak, who dares to care?

But if you take this steel material to forge weapons, well, you don't even have to wait for death, you just die on the spot!

At this time, the elusive shadow servant Ah Qi walked out of nowhere, and said lightly to Zhu Gaoxian: "There is news from the palace, and the emperor has asked you to meet you." ”

Zhu Gaoxian looked at Su Wu with a smile: "See, the buyer has come to the door." ”

Su Wu suddenly realized at this time, and admired and praised: "Lord, high!" ”

Zhu Gaoxian never thought of making too much silver by relying on steelmaking, as long as he wanted to build a Ming industrial city in Kongshan. And this requires the support of the emperor, and the best way is to pull the emperor into the gang, but if you want to pull the emperor in, you have to pay a sufficient price.

It is impossible for him to spend a huge amount of time and energy to build Kongshan Industrial City and give it to the emperor. This does have a huge impetus for the future industrial development of the Ming Dynasty, but for his Qi Wangfu, it is completely a loss-making business, Zhu Gaoxian is not a two-armed, he can't do this kind of thing.

Therefore, Zhu Gaoxian's initial plan was to get Kong Shan out and sell it to the emperor, as for how much he could sell, it depended on how much the emperor was willing to pay.

If the emperor doesn't want to pay, he can directly snatch Kong Shan, he is the emperor, he is the biggest, and Zhu Gaoxian can't help it. But the old man won't do this, although His Majesty the Emperor is sometimes a scoundrel, but this kind of thing, Zhu Di still can't do it.

If the emperor really snatched Kong Shan away as a scoundrel, Zhu Gaoxian would not matter, unless Zhu Di killed him directly, Zhu Gaoxian would inevitably prepare to rebel.

You rob my Kongshan, I rob your country!

……

Xuanwu Lake, with the Purple Mountain in the east and the Ming City Wall in the west, belongs to the royal garden. During the Hongwu Dynasty, Emperor Taizu Gao chose Xuanwu Lake as the central government of the Ming Dynasty to store the Yellow Book of the National Hukou Enlistment General Book and Tianmu Archives, and built the Yellow Book Library of Houhu Lake, which forbade the people to enter. Since then, Xuanwu Lake has been a forbidden place for a generation, isolated from the outside world.

Xuanwu Lake is close to the western foot of a lake, called Zhonghu, His Majesty the Emperor is interested today, sitting on the shore of Zhonghu Lake fishing.

The embankment and bridge between the continents are connected, they are integrated, there are mountains and rivers everywhere, the mountains are different, and the scenery is picturesque all the year round. Fish are raised in the lake, and lotus flowers are planted, in summer and autumn, the water surface is a piece of turquoise, pink lotus flowers are hidden in it, the lake is full of fragrance, elegant and clean.

However, His Majesty the Emperor did not enjoy this purity for long, and it was destroyed by a small beast.

Zhu Gaoxian carried a fishing rod, strode to Zhu Di's side, and asked, "How long has my father been fishing here?" ”

Zhu Di glanced at the bamboo fish basket beside him, and there was nothing in the basket except a basket of clear water.

"Just here." Zhu Di said calmly.

In fact, he had been sitting here fishing for more than two hours and had not caught a single fish so far.

As the so-called Diaoyu will never be in the Air Force, the Air Force will never admit it, and Zhu Di will never recognize his Air Force. Don't ask, just ask!

Zhu Gaoxian hung up the bait and shook the rod violently, stirring waves on the calm lake.

Zhu Di frowned slightly: "Get out of the way, Lao Tzu doesn't fish, you don't fish, I finally got in the mood to throw a shot, you little beast just ran over to spoil the scenery?" ”

"Hey, Father, that's not what I said." Zhu Gaoxian said with a big grin, "Erchen is not very good at fishing, the worse my fishing skills are, the more you can stand by your side." ”

Zhu Di thought about it, but he still pretended to be displeased: "If you like fishing, you can fish, if you don't fish, you will roll, I still need you to set off?" ”

Zhu Gaoxian smiled and did not speak.

……

Half an hour later, the goose feathers on the lake floated slightly, and the fishing rod in Zhu Gaoxian's hand trembled slightly, obviously a fish had bitten the hook. But instead of lifting the rod, he sweated profusely on his forehead.

Because Zhu Di was looking at him with murderous intent.

"Why don't you mention it?" Zhu Di gritted his teeth, "It's obvious that there are fish that don't even lift the rod when they take the bait, are you fishing or feeding the fish?" ”

Zhu Gaoxian was forced to have no choice but to lift the rod, and the lake suddenly bloomed with a splash, and a fat mandarin fish bit the hook and refused to let go. He didn't even dare to copy it by hand, so he hoped that this fat mandarin fish would break the rod and escape, leaving Zhu Di with the last bit of face.

Unexpectedly, the mandarin fish jumped out of the water, jumped into Zhu Gaoxian's fish basket, and threw himself into the net.

Zhu Gaoxian's fish basket has exploded, and more than a dozen big fish have crowded the fish basket to the brim, which is in stark contrast to Zhu Di's empty fish basket.

The Air Force is not scary, what is scary is that the Air Force has been discovered. What is more fearful than being discovered by the Air Force is that he is in the Air Force, but the people next to him have exploded.

Zhu Gaoxian: "......"

Zhu Di: "......"

"Catch a fart!"

Zhu Diqi's liver hurt, and he was about to throw the rod away, but found that the rod and fishing line were suddenly stretched, and it was obvious that the hook was bitten.

"Huh?" Zhu Di was pleasantly surprised, "Finally a fish has taken the bait?" ”

Even if you only catch one fish, one! can also let Zhu Di retain his last face!

Zhu Di hurriedly pulled the rod, but he always felt that something was strange, and he had an ominous premonition.

The rod broke through the water, but instead of a big fish, a clump of aquatic weeds hung from the hook.

Zhu Di: "! ”

"Ahem......" Zhu Gaoxian forcibly held back and didn't let himself laugh.

"I'm still fishing!"

Zhu Di was furious, directly broke the rod, and threw the ball of aquatic plants into the lake together.

It's just that he is still angry, and His Majesty the Emperor kicked the empty fish basket into the water!

After fishing all afternoon, I caught a bunch of aquatic weeds!

I'm angry!

Feeling that the killing intent on the old man's body was almost condensed into substance, Zhu Gaoxian hurriedly changed the topic: "The son brought a thing, please take a look at my father!" ”

This is to give Zhu Di the steps, in order to divert the embarrassment of Zhu Di's incompetence and rage.

Zhu Di was very satisfied with King Qi's sensibility, and waved his hand: "What did you bring?" Bring it to you! ”

Zhu Gaoxian took out a thick steel ingot from his sleeve and presented it to the emperor.

Zhu Di took the iron ingot, touched the texture, and couldn't help admiring: "Good steel!" It's a high-quality steel, and it's perfect if it can be used to forge weapons! ”

After speaking, Zhu Di looked at Zhu Gaoxian keenly: "This is the steel you made in Kongshan?" ”

This is the purpose of summoning King Qi!

Zhu Di didn't pay much attention to Kong Shan at first, but later noticed that something was wrong after hearing that King Qi was building a steel mill in Kong Shan.

Then he hurriedly sent people to secretly inspect Kongshan, only to find that King Qi had already built a whole steelmaking assembly line in Kongshan, such as mining raw coal, washing coal and burning charcoal, purchasing iron ore, and smelting steel!

Only need more detailed content, because the time is too short, Zhu Di did not check too much detail for a while, only knowing that Kongshan Steelmaking Plant not only has a high output, but also the quality of the steel made is excellent!

Zhu Gaoxian arched his hand and said: "As my father said, this steel ingot is from the Kongshan Steelworks. ”
