Chapter 491 Blast Furnace Ironmaking
The coal ore was found by Mr. Yu and the others on a collapsed gravel beach. The amount is not much, and if they want to mine it, they must dig a mountain.

Song Liyun quickly wrote down the location. This kind of resource is too hard to find and has many uses. She is happier than receiving ten thousand taels of silver.

Mr. Yu has gained a lot from this trip. What he is most satisfied with is not the flint, but the iron ore.

In the Wu Dynasty, no one had ever found ore veins in the Dilu Grassland.

According to the information provided by Song Liyun, there is iron sand on the banks of the Kara River where the Wuda tribe is located, and there must be iron mines in the mountains upstream. Sure enough, they found veins in the Kara Mountains.

In the Wu Dynasty, the mining of iron ore was not pure enough, as long as it was too deep, it could not be used. It was a surprise to get natural veins.

After getting the ore source, Mr. Yu went to Mida City immediately. He wanted to discuss mining with Zhao Tingduo.

Coal mines and iron mines are both major issues, and they must be immediately reported to the Garrison Palace to deploy personnel.

As soon as the words were finished, the three of them split up and got busy immediately. Yu Lao sent a letter to Huancheng, and Zhao Tingduo also went to the military camp to arrange people to go to the coal mountain to pick up ore.

Song Liyun returned to the backyard and looked for Wan Youyou everywhere.

She has something to trouble this research madman again.

As soon as he entered the side yard, he saw Wu Dan sitting in the flower hall on the porch talking and dancing.

In front of him, apart from a group of children such as Yiming, Erfan, Sanhe, Siyuan, Wuhong, Liuming, and Qibao, there are Wan Youyou, who also listens with great interest, and Abu, who is like an iron tower.

Speaking seriously, listening even more seriously, Song Liyun couldn't help standing still.

"...that piece of land is white, not a single blade of grass grows, as if covered with a layer of snow.

Mr. Yu said it was salt.

Why!It looks like salt, but it can't be put away.

I also tasted it, it was bitter and astringent, not salty at all..."

Erfan rushed to talk: "Bitter and astringent? Could it be poison?"

Wan Youyou said: "You can't do this, even if you want to taste it, you have to use animals, that is, you have experimental data first!"

Wu Dan rubbed the back of his head, and said naively: "That place is a dead land, there is no grass, no water, not even rabbits, so there is no way to find animals!"

Hearing this, Song Liyun finally couldn't help but say, "Wu Dan, refined salt can also be produced there!"

Her words made everyone present wide-eyed.

Wu Dan just said that the land of dead salt is bigger than the city of Mida. If it was salt, how much would there be?
Wan Youyou didn't doubt Song Liyun's words at all, but just asked: "Young Madam, why don't we collect salt from the dead, and buy it from Wu Dynasty?"

Abu also expressed doubts: "Young Madam, there is no salt on the grassland. If there is, the old man will tell us."

This is what everyone wants to ask. The salt eaten in the Dilu Grassland for thousands of years was purchased from the Wu Dynasty with a lot of money. If the salt from the dead salt land can also be eaten, why go all the way to buy it.

Song Liyun is full of confidence in what she said about extracting salt from saline-alkaline land.

In the earth's soil, salt is everywhere, only the concentration difference.

Before the end of the world, most people ate sea salt. Thanks to mining technology and convenient transportation, coupled with the control of state agencies, the price of salt was not high.

However, after the social order was chaotic in the last days, the seawater was polluted by nuclear weapons, and only the few wells on the mainland had to rely on salt.

Suddenly the price of salt soared and was manipulated by oligarchs, making it difficult for ordinary people to buy it.

Some people extract salt from the soil that has become saline-alkali land. The simple method is to consume a lot of clean and pure water.

However, clean water is also a precious thing in the last days of nuclear pollution.

But on the Dilu Grassland, water is no longer rare. You only need to put the saline-alkali soil into a large pot, add water to dilute and stir, set it aside to clarify, take some clean water, put it in a pot and boil it, and evaporate the water to get salt.

Song Liyun thought of those coal ores, and only now did he feel what good luck was.

She smiled at the bewildered faces: "Abu, find some people to take Wudan with you, go to the Dead Salt Field to fetch hundreds of catties of soil, and watch me fetch salt for you!"

The next day, the Mida City Company sent several teams.

Abu Wudan carried a sack on his back and led his people straight to the depths of the grassland. They were responsible for collecting soil, while the other two teams went to the coal mine.

In the city, Mr. Yu was pestering Song Liyun.

In his hand is a simple design drawing with a tall brick tower drawn on it.

In the Qing Dynasty, the process of iron ore smelting was to pile iron stones in an open space, surround them with flint and burn them for a long time.

Until the stone cracks and becomes a block containing iron slag, it is then sent to the blacksmith's shop for repeated hammering to produce the finished product.

From stone to discus, this step is the most difficult.

Now Song Liyun has come up with a blast furnace ironmaking method.

It can continuously burn molten iron, directly solve the most difficult first step, and even get pig iron with only a small amount of impurities.

Mr. Yu was so excited that he was trembling when he spoke: "Young Madam, what should I do with the refractory bricks?"

Due to the high temperature and long time of steelmaking, ordinary earth bricks and stones cannot be used to build blast furnaces, but special refractory bricks must be used.

"Using clay, quartz stone, and limestone to process refractory bricks, the shape is..." Song Liyun told Mr. Yu what he had learned in books.

Afraid that he might not be able to remember, Mr. Yu hurriedly took out his pen and ink to remember.

Wan Youyou, who has been silent all this time, has sorted out the content of the conversation: "Old Yu, I've already sorted out what the young lady said, please see if there is anything else you missed."

Looking at Wan Youyou's neat meeting minutes, Mr. Yu sighed, "I have to trouble Miss Wan to write more in the future, so as to write down everything Young Madam said."

Wan Youyou's eyes sparkled, but she lowered her eyebrows and said, "Don't worry, Mr. Yu, Yoyo will record it!"

Song Liyun's face darkened. She just said that when iron was made in a blast furnace, she also mentioned that the slag taken out is the best choice for road construction. It is not only as hard as iron, but also permeable to water and air.

Since iron can be smelted, calcining limestone to obtain cement is a trivial matter by the way.

Cement is also the first material of construction, almost a fetish of ever-changing things.

This one set made Yu Lao and Wan Youyou feel like they were walking in the starry sky, but they also felt that every item was simple and easy.

Even if Mr. Yu wanted to deny it, he couldn't convince himself.

Thinking about the wind wheel he saw in the Wuda Tribe, Mr. Yu's heart became hot.

If he hadn't seen the never-stop spinning wheels with his own eyes, he wouldn't have believed that it was the effect of the wind.

That is the erratic wind!
Apart from flying kites and blowing food, who would have thought that they could control the wind!
Playing the wind submissively is only the young lady's ability.

Old Yu remembered those rumors in the tribe again, so he gave Wan Youyou a task to write down every word Song Liyun said.

If you want to smelt iron, you must first make refractory bricks. You can go to the Wuda tribe to do this.

And coal mines.

Originally, Mr. Yu wanted to build the iron-making blast furnace in the Wuda tribe, but Song Liyun denied it.

Iron smelting, gravel, and coal washing are all heavy pollution, so it is better to choose the downstream of the river far away from the tribe.

Although it is too early to say that protecting the environment is everyone's responsibility, we cannot sacrifice the environment for the sake of the economy regardless of everything.

Song Liyun didn't want this world to become that polluted and destroyed earth.

In this way, mining, iron smelting, and cement were put on the agenda. Soon, there was news from Hecheng, and Zhao Tinglei wrote a reply letter himself.

Mining requires a lot of manpower. The garrison will allocate 5000 people from the Zhenbei Army to dress up and enter the Dilu Grassland.

This is the second time that 20 troops have been mobilized after Zhenbei Hou entered the grassland to rescue the Wuda tribe 5000 years ago.

The reason why they were able to mobilize 5000 people on a large scale without being afraid of Di Lu Wang Ting was because the Wang Ting had no time to take care of Mida City.

In order to reconcile the throne behind the princess, the four tribes have ended their years of superficial peace, and a melee is imminent.
