Chongzhen Undergraduates

Liuhe Mine is not located in Liuhe District at all, but in Yeshan Town at the junction of Jiangsu and Anhui.

Yeshan Iron Mine has a long history of development. As early as the Western Zhou Dynasty, it has been a place for copper mining and iron smelting. It can be said that the Han people started from bronze to iron tools here.Therefore, Song Yingxing's steelmaking experimental base was built here.

Before Zhu Youjian got close to the workshop, he already felt the threatening heat wave.It was the weather in June, and with this heat wave, Zhu Youjian actually felt the burning sensation of his skin through his clothes.

Regardless of the dissuasion of the people around him, Zhu Youjian bit the bullet and walked in.

"Your Majesty welcomes you!" Zhu Youjian immediately regretted that he had come in, because there were a group of "blacks" kneeling on the ground who couldn't see their faces clearly.

"Your Majesty, why are you here?" A thin, shirtless old man walked up to him with a smile on his face.

Zhu Youjian saw that this person's skin was black and red, and there were large areas of half-colored peeling on many parts of his body. The peeling area was slightly red, and the non-peeling area was black.

Especially on his face, there were obvious peeling marks on the whole face, and in some places more than one layer had peeled off.

"Song Aiqing, what's your face?" Zhu Youjian finally recognized that it was Song Yingxing.

"It's okay, the fire is big, it's roasted." Song Yingxing grinned indifferently, showing his white teeth, making his whole face even more ferocious.

"Stop work, stop work soon." Zhu Youjian couldn't take it anymore, and everyone in the workshop looked like Song Yingxing.

"What's wrong with the emperor? Is it because we didn't do well? Please give the emperor some more time, and we will definitely do it." When Song Yingxing heard that Zhu Youjian was about to suspend work, he thought it was the emperor who had lost his temper, and almost begged bitterly. Zhu Youjian.

"Aiqing, how can I bear it!" Zhu Youjian pointed to the workshop and sighed one after another: "This is not a place for people, this is hell."

"Your Majesty, don't filter, the place where iron is made is like this. It's just that the temperature of our furnace is higher, and the weather is hot recently..." In Song Yingxing's opinion, this is nothing at all.

"Go buy the best watermelon and find the coolest spring water. I want to watch them do their work here." Zhu Youjian ordered Ji Biao behind him.

"Your majesty, you can't stay here, it's too hot here." A little old man who looks like him beside Song Yingxing snapped up.

"This is my elder brother Song Yingsheng, the former prefect of Guangzhou. I called him here." Song Yingxing quickly introduced.

The prefect of Guangzhou is the mayor of Guangzhou.Zhu Youjian didn't know how to speak for such a big official, who was actually nesting in Lian Tie.The brothers' support for Zhu Youjian can be seen.

"If you don't go out, I'll stay here. Either everyone stop working together, or I'll stay here with you." Zhu Youjian had no other way to express his emotions, he could only play tricks.

"Okay then! Everyone stop. Let's take a look around with the emperor." Song Yingxing had no choice but to let the emperor stay here.

There are more than 500 people in the entire experimental base, most of whom are young people. This is what Zhu Youjian emphasized, so that Song Yingxing can train talents during the experiment.

Among them, only

Mining is not their business. The ore is sorted by the mining area and sent directly to here.The task here is to design blast furnace ironmaking based on the data and try to find out the technology of steelmaking.

The coke was also coked from Huainan and sent here. I thought that the Taipingfu mine was still in the early stage of mining. In order to hurry up, the base was built here.

The blast furnace ironmaking technology is mature, but the steelmaking technology always fails because it is too difficult.

According to the star data provided by Zhu Youjian, the crucible steel training can be done, but the output is too small, which obviously does not match the molten iron output of the blast furnace.The high-carbon steel produced by this method can produce some tool steels, but it is far from meeting the needs set by Zhu Youjian.

However, converter steelmaking requires oxygen blowing. In the absence of a power source at present, it is quite difficult to rely on manpower or animal power to blow oxygen.At present, Song Yingxing and the others have only built an experimental small converter, and a converter of this scale is still full of difficulties.

However, phosphorus, which is the most difficult to remove in China's iron ore, needs an open hearth furnace to solve it.The open hearth furnace needs gas or heavy oil as fuel, and Zhu Youjian can't provide these things at all.

Later, Zhu Youjian finally recalled the alkaline converter, which used dolomite clinker fired at high temperature and mixed with tar to make an alkaline refractory brick lining. During the smelting process, air was blown in and quicklime was added.This allows the entire reaction to proceed under alkaline high-temperature conditions

, the oxidized phosphorus combines with lime and remains in the slag without returning to the steel.This speeded up Song Yingxing's experiment a lot, and they are mainly doing this kind of experiment now.

However, the oxygen blowing problem still cannot be solved.

Finding a shady place outside the workshop, Zhu Youjian killed a watermelon frozen in the ice spring with his own hands, and handed it to Song Yingxing and Song Yingsheng.

"I came here this time to tell you that the conditions in Taiping Mansion are already met. You need to prepare and move the experimental base to Taiping Mansion."

Zhu Youjian looked at the sun above his head, and really couldn't bear to let these people continue to toss. He found that he had given wrong information, which caused Song Yingxing and the others to do useless work.

In fact, the technology explored here is already very remarkable, but because of the problem of the power source, some things cannot be achieved by manpower alone.

In the case of theoretical drawings, the steam engine is actually not complicated.The so-called sealing material used in most of the crossings is not rubber at all but asbestos.Watt's improved steam engine was created in 1775, vulcanized rubber was invented in 1839, and the maximum working temperature is 50-80 degrees Celsius.Apparently rubber has nothing to do with steam engines.

Zhu Youjian found that he reversed the technical difficulty of steam engine and steelmaking. Obviously, steam engine is simpler than steelmaking.In other words, it is easier to invent application technology than to invent materials.

Instead of spending it here, it is better to concentrate on getting the power out first.Judging from the progress of the current technology tree, many problems are stuck in the power.

For example: the turning of gun barrels, the centrifuges used to make gunwool, the pumps needed for large-scale coal mine excavation, and the oxygen blowing pumps used for steelmaking.

Working at such a high temperature, it is better to let them take a break when they move, and wait for the news from the steam engine.

"Your Majesty, I don't want to move. I've already spent so much money, and if I stop working for a day, it's all money." Song Yingxing slipped his mouth. It's obvious that the working environment here is so bad because he thinks he saves money by spending too much money. .

"How much did it cost?" Zhu Youjian felt sorry for the money, but climbing the technology tree itself was a pile of money.

"It's already cost 20 taels, and more than 100 people died. The price is too high." Song Yingxing said, tears falling down.With tears in his eyes, he gnawed on the watermelon.

The people sitting around were silent when they heard this, the scene was completely silent, only the cicadas on the tree were calling.

Zhu Youjian stood up, walked to the front of the crowd, and said to these people: "I will give you another 50 taels in Taiping Mansion. Let's start again. OK?"

The emperor didn't know how to dissuade these people, the only thing he could give was unlimited support.

Song Yingxing quickly stood up, quickly knelt on the ground, and kowtowed to Zhu Youjian: "I thank the emperor for your kindness!" All of a sudden, Zhu Youjian knelt on the ground around him.

As a top talent obsessed with technology, Song Yingxing's failure in the imperial examination led him to hope to be famous in history like Cai Heng. It was the opportunity given by Zhu Youjian that made him see hope, so he worked so hard.

"You all get up. It's not you who thank me, but I want to thank you, and Daming will thank you too."

As a later generation, how could Zhu Youjian not understand the importance of steel.The so-called torrents of steel on the battlefield are all cast from furnaces of molten iron.

Chapter 2 Twelve: The Wounded Soldiers Left Behind

When Zhu Youjian came to Huai'an again, it lost its previous hustle and bustle, like another city.There are beggars with broken limbs and arms everywhere in the city, and they almost crowd the small Huai'an city.

Those salt merchants who fawned on Liu Zeqing at the beginning have long since disappeared, and the canal going north has also lost its busyness due to the confrontation between the North and the South. Huai'an has become a city that seems to be forgotten.

It turned out that those domineering Liu Zeqing's subordinates were gone, replaced by wounded soldiers like beggars wandering on the streets.

Huai'an, the large-scale rear field hospital base established by Zhu Youjian, has become a shelter city for wounded soldiers.

"What's the matter with the wounded soldiers on the street?" Zhu Youjian's face was so ugly that he could wring out ink.

Cheng Xianzhen was about to kneel down with a bitter face, but was glared at by the chief.The first few right-hand men who followed Zhu Youjian to the south knew that Zhu Youjian didn't like to kneel.But after arriving in Nanjing, because of his status as the emperor, Zhu Youjian got used to the rule of people in Ming Dynasty kneeling at every turn.

"The remaining wounded soldiers are those who are not suitable to continue serving as soldiers after being disabled. According to the regulations of the Ministry of War, their pensions are very small. Most of these people are from the north, so they are homeless."

Since the beginning of the year, Daming has fought a total of four battles, three of which were handled by Zhu Youjian himself.Whether it was the Battle of Suizhou, Fengyang, Anqing, or Tongshan, there were a large number of wounded soldiers.

Coupled with the ones sent from Shandong, Huai'an naturally became a shelter for wounded soldiers.
