Chapter 1031: Blast furnace ironmaking (2 in 1)

After coming out of the palace, Li Zexuan went directly back to Yunshan. He

had to quickly draw the drawings of the equipment needed for ironmaking in the

past two days, because these things are not easy to make.

"Lady, I've been closed in the study in the past two days. If there is no

emergency, don't let anyone disturb me!"

Back home, Li Zexuan said to Han Yuxi.

This is good for Yunshan Bieyuan, because it is far away from the main city,

usually inaccessible, very quiet, and the scenery here is beautiful, and it is

a treasure place for self-cultivation!

"Yeah! But Xianggong must not be exhausted to break his body. There is nothing

short of our family now, why bother so desperately?"

Han Yuxi clearly understood what Li Zexuan was going to do, and it was not the

first time that it was similar, so she said with a worried look.

"Haha! Don't worry, the lady, with your physique, you can't be exhausted! If

you don't believe me, wait for the mate, and then fight the lady for three

hundred rounds!"

Li Zexuan smiled and squeezed Han Yuxi's pretty face, and then said in a

serious manner.

Of course, even though he said so, he still cared about his own wife very

well.

"Msang Gong~!"

Han Yuxi was ashamed and angry, she stomped her feet and said a little, but Li

Zexuan had already slipped away at this moment!

……………………………

"Blast furnace ironmaking, if you want to improve ironmaking efficiency, you

must build a blast furnace!"

In the study, Li Zexuan muttered to himself facing a large blank sheet of

paper on the book case.

In modern industry, ironmaking methods include blast furnace method, direct

reduction method, smelting reduction method, plasma method, etc. Blast furnace

ironmaking is the main method of ironmaking in modern society, and its output

accounts for more than 95% of the world's total pig iron output.

Blast furnace ironmaking is a complicated process. It uses iron ore, limestone

and coke as raw materials. The reaction in the blast furnace is mainly divided

into three parts. The first part is the process of preparing the reducing

agent, the second part is the main principle of iron smelting, and the third

part is the process of removing impurities and forming slag. However, the iron

smelted in the blast furnace is not pure and contains a small amount of

impurities, so it is called pig iron.

During ironmaking, the raw materials iron ore, coke and limestone are added

into the blast furnace (ironmaking furnace) in a certain proportion in layers,

and a large amount of oxygen-enriched air heated by the hot blast furnace is

blown into the blast furnace from the air inlet to make the coke burn to

generate carbon dioxide and carbon dioxide. Then it reacts with the hot coke

in the upper layer to reduce it to carbon monoxide;

Carbon monoxide is added from the top of the furnace and reacts with the

falling iron ore. The iron oxide is gradually reduced to liquid iron, commonly

known as molten iron. After the reduced liquid iron has accumulated to a

certain extent, it is released from the furnace bottom. The limestone added

during ironmaking plays the role of slagging, and the purpose is to make the

gangue (the main component of which is silica) in the iron ore react with

limestone to form calcium silicate floating on the molten iron. Slag is formed

and separated from the molten iron.

In fact, blast furnace ironmaking is not the patent of modern people. As early

as the Song Dynasty, this method of ironmaking was popular.

According to historical records, during the Yuanfeng period of the Northern

Song Dynasty, the imperial court warriors set up blast furnaces on both sides

of the Bianhe River, and the red light of ironmaking reflected the sun, day

and night. At the peak of production, the annual output of steel in North

China alone reached more than 70,000 tons. It should be understood that the

British Empire reached an annual output of 70,000 tons of steel only 700 years

later. At that time, it had already begun the industrial revolution.

This shows how powerful the Song Dynasty was at that time! It's just that

there were fewer famous officials and sages at that time! If Li Er's team of

ministers of civil and military affairs is sent to the Song Dynasty, maybe it

can really create a super grand age!

"Tsk tsk, fortunately, my son, I have traveled to the Tang Dynasty. If I

travel to the Song Dynasty or after the Song Dynasty, how can I use blast

furnace ironmaking to pretend to be force?"

Li Zexuan thought he didn't know where he flew, just listened to him muttering

to himself.

In some later generations, the protagonist traveled to the Song Dynasty and

the Ming Dynasty to make blast furnace iron making. Those are pure nonsense.

If the protagonist really wants to do that, he can only pretend to be forced

and get beaten in the face!

Shaking his head and shaking off the mess of thoughts in his mind, Li Zexuan

pondered slightly and began to draw drawings. At this time, he already had a

three-dimensional model of the ironmaking blast furnace in his mind, and he

naturally became a humanoid printer.

He intends to completely reproduce the blast furnace frequently used in modern

ironworks, and then modify it according to the existing conditions of Datang.

This is not an easy job.

The structure of the blast furnace is not that complicated. The "big movement"

in the late 1950s called on the people across the country to smelt steel. Even

some elementary school students, production team villagers, and grocery store

salespersons formed iron smelting teams to build blast furnaces. Come to

steelmaking and ironmaking.

But the structure of the blast furnace is definitely not simple. The technical

level of the blast furnaces in modern China is about the same as that of the

Song Dynasty. Theoretically, they can make iron, but the technology is not

well mastered, so most of them can't be ignored. The blast furnace Li Zexuan

wanted to build was not the kind of inferior product.

Generally, a complete blast furnace is composed of furnace shell, furnace

throat, furnace body, furnace waist, furnace belly, hearth, furnace bottom,

furnace base, furnace lining, and furnace throat guard plate. The furnace

shell refers to the outermost layer of the blast furnace. Its main function is

to stabilize the blast furnace and protect the furnace body from leakage;

The furnace body, blast furnace iron ore is mainly indirectly reduced in this

area of the furnace body;

The throat, the uppermost part of the blast furnace body is the throat. The

shape is like a cylinder, the raw materials for ironmaking are added from the

furnace throat, and the gas is discharged from the furnace throat;

The throat guard plate refers to the protection plate of the throat;

The furnace waist, the place with the largest diameter of the blast furnace,

which connects the furnace body and the furnace belly;

The furnace belly, in the shape of an inverted cone, is the main area for

melting and slagging in the blast furnace;

The hearth is used for fuel combustion, slag-iron reaction, storage and

exhaust gas, and is similar to a cylindrical shape;

The bottom of the furnace is located at the bottom of the blast furnace. The

bottom of the furnace is subjected to the static pressure of charge, ** and

molten iron, and is also subjected to high temperature, mechanical and

chemical erosion of 2000～4500℃;

The main function of the furnace base is to evenly distribute the weight of

the blast furnace to the ground, and its shape gradually expands from top to

bottom. Generally round or polygonal to reduce the uneven distribution of

thermal stress;

Time passed bit by bit, even though Li Zexuan had the super speed of a

"humanoid printer", it was already dark after all the structures inside and

outside a blast furnace were drawn.

"Boom~!"

Just as Li Zexuan was immersed in the sea of construction machinery, there

were two knocks outside the door, followed by another footsteps. Li Zexuan

frowned first, and then stretched out again, because he just listened to the

footsteps. , I knew it was Han Yuxi who opened the door and came in.

Although they were married for less than a year, the couple had already

engraved everything about each other in their hearts, including the sound of

footsteps.

"Msang-gong, let's eat something first! It's not too late anyway, the body is

the most important thing!"

Han Yuxi put the food box on another table and said back to Li Zexuan.

Li Zexuan put away his thoughts, clapped his hands, got up and walked towards

Han Yuxi.

"Haha! Thank you lady for enjoying the meal! Hey! I didn't feel hungry at

first, but when I smelled the aroma of this meal, the gluttons in my stomach

started to make trouble! The ** of cooking in the sky met the lady, and he

might be willing to bow down to the wind!"

Li Zexuan sat down and said with a smile when Han Yuxi brought out two

fragrant dishes from the food box.

"Sang Gong, don't make trouble! Eat it!"

Han Yu sighed and said softly.

"Haha! Eat! Eat! Isn't this eating? Lady, do you want to come and have some?"

"No, let's eat it! My concubine has already eaten it!"

Han Yuxi responded, and then cast his eyes on the large drawings on the book

case.

The intricate and tortuous lines on the drawings seem to have life, and

outline a huge and majestic blast furnace. It may be that Li Zexuan’s painting

is too lifelike. Han Yuxi seems to be able to feel the terrifying heat in the

furnace, making him unable to help Two steps back.

"What? The lady is still interested in engineering matters?"

Li Zexuan asked with interest while chewing the food.

"No! Just take a look at the concubine body!"

Han Yuxi came back to her senses, she thought for a moment, and then said:

"Seeing that Xianggong's drawings are so good, she was thinking that if

Xianggong used this technique in painting, she would definitely not lose to

Yan Shaojian (coming soon). Supervisor Yan Liben)!"

Don’t think that engineering drawings are all blunt and aestheticless lines.

The key is to look at the craftsmanship of the person who draws them. The

engineering drawings of people with superb skills can definitely feel the

beauty as much as artistic works. Li Zexuan belongs to this now. Kind of

people.

"Hmm! Just leave it to Yan Shaojian and the others for painting. You and I

don’t have that free time! Although we are excellent, we can’t do everything.

We have to leave a way for others~?"

Li Zexuan cocked half-jokingly.

"Punch~!"

When Han Yuxi heard the words, she covered her mouth and smiled: "Msang-gong,

how can I boast about myself? Are you ashamed?"

Li Zexuan rolled his eyes and said, "Why can you praise me, you can't praise

me as a husband?"

Han Yuxi shook her head, too lazy to care. At this moment, she suddenly

remembered something: "That's right! Xianggong! The drawings you drew last

time were locked in the cabinet by your concubine, so why didn't you use it?

Did you forget? ?"

What she said were actually the drawings of the generator that Li Zexuan drew

last time.

"Don't use it for the time being! It's the New Year's Eve right away, I don't

bother to toss about it for my husband! Let's have a stable and stable year!"

Li Zexuan replied.

"Yeah! I used to spend the New Year with Tie Dan and Dad. Can Xiang Gong take

them over for the New Year this year?"

Speaking of the New Year, Han Yuxi's eyes instantly glowed with a dazzling

look. Although she is a woman, but she is only 13 or 14 years old, she may

still retain some innocence in her heart, looking forward to the excitement

and joy of the New Year.

"Haha! What's wrong with this? As long as the lady is happy, don't talk about

this little thing, that is, I want the moon in the sky to be picked back for

your husband~!"

Li Zexuan laughed.

Reasonable Han Yuxi, even if he doesn't say it, he will do that when the time

comes. How can his husband and brother-in-law be the husband and wife of the

New Year! Naturally, it is the two families who are celebrating the New Year

together!

"Hehe! The moon on that day was bare, what did the concubine want to do? But

the concubine still thank you, Xianggong, for agreeing!"

Han Yuxi smiled and said.

Apparently, she had looked at the moon with the telescope of the college

before.

"Well, what's the reason for the family to thank you? Hiccups~! Okay, I'm done

eating for my husband! Maid, let's go and rest first! I will go to bed later

tonight!"

Li Zexuan put down the bowls and chopsticks, burped contentedly, and said.

Although the general drawings of the iron-making blast furnace were drawn,

there are still many details that he needs to consider one by one.

"Xiangong, can't you paint tomorrow? Don't worry about this time?"

When Han Yuxi heard it, he knew that Li Zexuan was going to "work overtime"

tonight, so he persuaded him.

"Hey! Some things have to be vented. If this tone is vented, it will take a

long time to find it again next time! Don't worry, lady, I will take a rest

when I'm sleepy, absolutely not strong!"

Li Zexuan touched his daughter-in-law's black and smooth hair, and said

softly.

In fact, with his current martial arts cultivation skills, he can handle it

even if he doesn't sleep for three days and three nights!

"That's good! Xianggong, you have to speak up! Concubine body will not disturb

you!"

Han Yuxi knew that Li Zexuan's decision could not be persuaded to come back,

so he compromised.

"Hmm! Lady, go and rest!"

Li Zexuan said with a smile.

Han Yuxi nodded, and took the tray and food box out of the study. The study

suddenly became quiet again.

"Fire-resistant! First of all, the furnace must be fire-resistant!"

Li Zexuan looked at the structure drawing previously drawn in a daze, and he

muttered to himself after a moment.

"Yes! Refractory cement! Get the refractory cement by the way! Recently I

asked Fubin to go to Shuozhou quickly and get some bauxite back!"

Suddenly, Li Zexuan's eyes lit up and he said excitedly.

In Shuozhou, Shanxi, his former university roommate came from this city. That

guy really had a mine at home, not a coal mine, nor an iron

mine~www.mtlnovel.com~ but a bauxite mine. Li Zexuan had a National Day

holiday one year. At that time, I went to the scene with him.

Coincidentally, his roommate boasted about the history of Shuozhou once

before, saying that the name "Suozhou" had already existed in the Northern

Zhou Dynasty. Although the name was changed to Mayi County in the Sui Dynasty,

Li Yuan changed it back in the Tang Dynasty. It can be described as a

historical city.

Now Li Zexuan, relying on his memory, can even mark the detailed location of

the bauxite mine of his former roommate's house on the map!

"Hey! Old classmate, I'm sorry, let me use your mine first! Shouldn't you

mind?"

Li Zexuan talked to "air" like a neurotic.

Bauxite is also called high-alumina clay. The main minerals are diaspore,

boehmite, gibbsite and kaolinite. This stuff has high alumina content. After

grinding and calcining with limestone, it is refractory cement; Pressed into

bricks can be fired into refractory bricks, the lowest refractory temperature

can reach more than 1,500 degrees!

In fact, the small blast furnaces in the Song Dynasty were generally built

directly using clay, but their lifespan was not long. Li Zexuan wanted to

build a blast furnace closest to the type used in modern steel plants, so this

type of high-grade refractory used in modern steelmaking furnaces Use the

material as it naturally works!

What's more, he still has a bauxite mine "left behind" by his old classmates!

No need for nothing!
