Coal is a good thing, and modern society cannot develop without it.

my country's ironmaking began in the Spring and Autumn Period. It was a block ironmaking. At a relatively low temperature, iron ore was reduced in solid state to obtain sponge iron, which was then forged into iron nuggets.

Generally, ground furnaces, flat furnaces and shaft furnaces are used, and pig iron with a carbon content of 3% is quickly smelted to be cast into tools.

Ironmaking requires manganese ore, limestone and coke, which are all pulverized and mixed in a certain proportion and sent to the blast furnace. A thousand-degree hot air is blown from the lower part of the blast furnace to burn the coke to produce a large amount of high-temperature reducing gas gas, thereby heating the charge. and cause a chemical reaction.

Iron ore begins to soften at about 1100 degrees, and melts into molten iron and iron slag at 1400 degrees, which are stored in layers in the hearth.

After that, the gate is opened to carry out tapping and slag operation.

□□In the early days, the grandparents who were dragged down by their status were sent to the countryside to make steel, so they studied the iron-making process for a while.

They have practiced indigenous methods of steelmaking, and other communes have not succeeded, so they smelt iron in blast furnaces built by black people.

Make grandparents very proud, and tell their grandsons every time they drink happily.

He Qinghuan's ears were calloused.What temperature, what ratio, how to build the furnace, no

From ten, get a small blast furnace and practice first

But the iron hasn't landed yet.

He Qinghuan wandered around the rally holding two skewers of mutton skewers. Of course, the patriarch's younger brother was followed by two people.

The things exchanged at the rally are mostly food, pottery, salt, coarse salt, which is far worse than the salt you cook yourself.

There are also beautiful feathers, seashells, stones, mainly exchanged by women, whenever women like these lovely baubles.

Even the baskets of crooked melons and jujubes were exchanged.

Walking to a tent, two warriors had just fought and left for unknown reasons.

The crowd huddled together, and He Qinghuan watched from afar, because Xia Tian was sweating from a group of men, so they didn't go.

In the center of the crowd, a beautiful girl was tied up with a rope. She was really beautiful, not the one who felt beautiful after degraded vision.

Such a beautiful girl is only wearing a small leather skirt, and her healthy body can be seen at a glance.

The girl pursed her lips stubbornly, staring at the men in front of her with angry eyes, without showing any sign of weakness.

This temper is too strong.

Even though He Qinghuan was used to women's minimalist clothes, a group of men coveted a young girl still made him very uncomfortable.

A warrior next to him was covered in hair, holding a stick, pointing to the buyers in the crowd: "Do you offer ten gazelles?"

"You bring out a bison and add five bags of salt?"

He Qinghuan saw the hairy man gradually smile, and shouted loudly from behind: "What do you think this is?"

The hairy man looked over, and saw that the boy was holding an unusually beautiful stone in his hand, light blue, like the color of the sky.

The hairy man squeezed through the crowd, took it over and looked at it carefully; "You want to exchange this?"

"Well, Master Luan Xi gave it to me yesterday."

Oh, Lord Luan Xi gave it to me.

The hairy man nodded; "Okay, which woman you take away."

The girl was brought in front of He Qinghuan and looked at him fiercely.

"Untie it, untie it, how can you treat a girl like this."

The hairy man looked at him: "This woman is wild, let her go and run away."

"Forget it, your hands are broken."

The hairy man was untied, the girl looked at her wrist, and He Qinghuan handed her the mutton skewers: "Eat a skewer first, it's so refreshing."

"Aren't you afraid of me running away?" The girl looked at him provocatively.

"You can't help yourself, can you tell me why you were tied up and exchanged?"

"Because their tribe defeated our tribe, I am a prisoner." The girl took a bite of the mutton skewers, because she resisted too much and hadn't eaten for several days.

He Qinghuan watched her devouring her food: "Eat slowly, eat something first, and we'll drink mutton soup when we return to the camp. It's delicious and easy to absorb, and it's good for your body."

"What is mutton soup?" The girl was curious, even if she wanted to run away, she would have to eat enough before running away.

"It's made from the sheep's body, bones, internal organs, and mutton in one pot."

"Do you even eat bones?" The girl felt that their tribe was poorer than her own, and her own tribe didn't eat bones or offal.

He Qinghuan said: "You can tell by looking at it, it's very delicious, what's your name?"

"cocoa."

"how old are you?"

"13 years old."

"What tribe are you and why were you attacked?"

"Our tribe has few people and poor people, so they bully us, what else is there for?" Ke Ke said angrily.

The two walked back while chatting, and soon smelled a strange fragrance.

"Is that your tribe?"

Ke Ke ran over, and He Qinghuan followed closely.

Sister Meihua looked at a lively girl who looked like a fool and said, "Want to eat mutton skewers?" "

He Qinghuan said from behind; "She will be a member of our tribe in the future, and I will exchange it with turquoise."

Sister Meihua immediately asked, "What will you do?" Turquoise is a precious stone, which is very rare to see. If the girl is disobedient and lazy, then it will be a compensation.

Ke Ke knew what she meant when she heard it: "Hmph, don't look down on people. I'm the one who killed a Gazelle independently."

Sister Meihua also snorted and said disdainfully; "Can you weave baskets? Can you make pottery? How many kinds of food do you know?

Nothing, still arrogant here!

Do you know, our God. . . .We, Qing'er, exchanged you back to save you. If someone else exchanged you, we would not know why. "

Ke Ke knew that she was telling the truth, but she couldn't bear to lose face and turned her head and said, "I only listen to him." She regained her dignity.

Ke Ke knew the greed in those undisguised eyes surrounding her, that's why she was angry.

Qing'er looks easy to talk and gentle, a hundred times better than those people.

So Ke Ke walked up to He Qinghuan and said, "Qing'er, I will listen to whatever you say."Others can't guarantee it. "

Sister Meihua laughed secretly, this little girl thought she was special to Qinger, she knew it when she was in the tribe, and everyone heard what Qinger said, you, just hide and cry.

He Qinghuan said: "I haven't thought of asking you to do anything yet, so how about it, you tell me about your tribe."

Coco said happily: "Okay."

The two sat in the shade and chatted.

It turns out that Coco's tribe is dominated by women, and their patriarch is a beautiful woman who is also their mother.

They make a living by having children with warriors from other tribes. Every year at the end of summer and early autumn, young women of childbearing age go to spend the night with warriors of other tribes and exchange food. to his father.

Then exchange for food.

Usually, when warriors pass by their camp, they can also exchange food for the night.

Some warriors lived in their camps, hunted for them, and did not leave until they were pregnant with children.

Waiting for the second year to come over to change the child, the method is flexible and changeable.

The boys are taken away, and the girls are left, so that their tribe is all women.

He Qinghuan looked at Keke and told him these things in a normal tone, without even a hint of shame.

Ke Ke said: 'I will be able to have children next year. "It seems to be saying that the flowers will bloom next year.

He Qinghuan was shy.

"Where is your tribe?"

Ke Ke pointed to the northwest: "Over there."

"We are also in the northwest, let's go and see your tribe when we go back."

Coco was pleasantly surprised: "Really?"

"How many people are there in your tribe?"

"More than 100 people, adults and children."

"Are you going to spend the winter in Luan Xi's cave?"

"Go, we don't have to pay food, because we don't have any, just pay a young girl."

He Qinghuan was really upset.

"Well, are you willing to join us? This is the most secret thing, no one can tell, you can discuss it with your patriarch yourself.

If you join us, you are protected by us, we are family.

Coco, do you know that the Aruguya tribe now scalds the faces of the captured people and treats them as slaves? "

"I know, when I was arrested, I heard that man said."

"Coco, the way your tribe survives, sooner or later it will be absorbed by other tribes.

If the Arugaya tribe wants you to perish, you don't even have the power to fight back.

They haven't touched you all this time because you are all women and will consume their food, so they don't fight with you.

But other tribes are not guaranteed to hit your tribe's idea. "

"I am now a member of your tribe. When I go back, I will tell the patriarch. Qing'er, you are so kind."

The girl looked at him with her characteristic eyes of admiration.
