Chapter 153 155 Steel and the Old Man (for subscription)

"Really!"

Lou Gao excitedly jumped up to the height of a person, and after landing, he was about to come and hug Tang Sangang with a move, but Tang Sangang had already known this guy's impatient temper, and teleported away.

"Don't worry~ It's dozens of times more difficult to drive a machine that flies freely into the sky than a steam train! I can't make it for you now, so you should worry about making steel first."

Looking at Tang Sangang's playful smile, Lou Gao knew that this kid was sure of himself, but what a machine that can make people fly into the sky looks like, I really want to take a look.

"Even if it can't be made now, it's okay for me to take a look."

"No! There will be no mystery after reading it."

After talking about Tang Sangang, he disappeared immediately, leaving Lou Gao gnashing his teeth, clenching his fists and stomping his feet alone.

Referred to as impotent rage.

It took several days before Lou Gao expelled the idea of ​​flying machines from his mind, and then concentrated on continuing the work of converter steelmaking.

With the steam blower, the problem of wind power was solved, and the second converter steelmaking was finally able to continue.

After the steel ingot was melted by Huowu, this time insert the blowing pipe into the furnace mouth and aim at the molten iron, pull down the control lever, and start in the first gear. The wind is obviously much stronger, and rich oxygen enters the molten iron, making it maintain its blazing red color. , The molten iron also raised flames, added limestone, and then pulled down the control lever, and the second-level wind was sent up. At the same time, the iron ingots were poured into the converter, and the flame magnified thousands of times in an instant!
Like a rocket jetting flames, the orange-red heat rushed out of the converter and went straight to the sky!
The molten iron in the converter was overwhelming, and even Huo Wu felt it was hard to look directly at it. The dazzling light was like the sun in the sky, visible but untouchable.

Silicon and manganese were oxidized first, and the temperature in the furnace had reached [-] degrees at this time. At such a high temperature, the carbon in the molten iron combined with oxygen to form carbon monoxide, which stripped the excess carbon in the pig iron. At the same time, a large amount of carbon monoxide was poured The incoming air escapes to the furnace mouth, and violent combustion occurs in the flame. At this time, the converter is like a violently burning alcohol blowtorch. The flame rises in a cone shape, almost igniting the roof of the factory!

The gas burned and expanded instantly, and the explosion sound was louder than the sound of a steam engine plus a blower. The workers were startled and backed away. They had never seen such a scene before, but Lou Gao and his apprentices With a face full of excitement, the huge momentum was like a roar, and the steel flames roared announcing that he had come to this world!
Looking at the blowing tube wrapped in flames, fortunately, it is also made of alloy, otherwise it might melt directly under such high temperature.

It only takes 10 minutes to complete a furnace of molten steel. Compared with the ten hours of open hearth steelmaking and the hard mode of electric smelting electric arc furnace, it is not difficult to imagine that converter steelmaking can be quickly accepted by the world.

After the molten steel is tempered, in order to ensure the quality, pour a bucket of aluminum water at the end. The melting point of aluminum is about 660 degrees. , and then help you re-smelt the mold.

The aluminum and the oxygen in the molten steel form alumina, which is lighter than iron, and the unreacted pure aluminum floats on the surface. At this time, the steelmaking is complete, and Lou Gao controls the winch to slowly pour the molten steel into the mold that has been prepared. At the same time, be careful not to let the slag pour out.

The molten steel gradually cooled down and turned into dark red steel ingots. Bright smiles appeared on everyone's faces. This is a historic day!It is also one of the test points in the future history books!

In June of the first three years of Douluo's new calendar, the first furnace of molten steel in Douluo Continent was successfully refined in the Wuhun City Industrial Zone at that time. Entering thousands of households has completely changed people's lives.

Lou Gao was full of excitement, and took out a hundred forged steel from the storage soul guide, and compared it with the cooled steel ingot. There was no slight difference between the two, and it was a black iron ax that condensed martial spirit. The blade is flat on one side and can be used for casting and chopping things.

Lightly tapped twice, the sound from the two steel ingots sounded exactly the same. However, as a master craftsman, Lou Gao heard a different feeling. Lou Gao stopped to look at all the steel ingots, and he knew that the properties of all the steel ingots were exactly the same, and there would be no big difference in the results of the hundred forging steel due to the different forging masters.

An ax split the steel ingot into two pieces. Through the comparison, Lou Gao sighed softly.
"The quality is indeed better. This hundred-forged steel will eventually be eliminated."

"Silong, Siyu, Sidis and Snow, you see, blacksmiths are going to be eliminated after all, if you don't make changes according to the actual situation, you will only end up as a memory of history."

The four apprentices looked at the cross-sections of the two pieces of steel and nodded one after another. This furnace of excellent steel ingots is comparable to the output of a blacksmith for a year, plus those machine tools that can be used with a little learning, the sunset of the blacksmith has come .

Blast furnaces still need fire-type soul masters to maintain the temperature, while converters can produce a large amount of steel as long as the molten iron is transported. If efficiency is not considered, let all blacksmiths refine pig iron by themselves and transport all of them to Wuhun City Industrial Zone. The output will be extremely scary!
Changes have come, but fortunately they keep up with the times.

Tang Sangang was very happy when the molten steel was successfully smelted, which meant that the material problem that restricted the steam train running on the earth was finally solved, and the processing of many parts of the steam locomotive was complicated, plus the large cylinder, it did not take a few months It is impossible to make the first prototype. It seems that Lou Gao will be busy for a while.

The development of Wuhun City is still on schedule, and now the ore has to be purchased from the local lords. When the Wuhun Empire is established, these people will no longer be able to get a copper spirit coin!At that time, a series of railways from the mine to Wuhun City will be directly built, which will not only give extra job opportunities to the civilians along the way, but also promote the Wuhun Empire, killing two birds with one stone.

In the current Wuhun City, the Pope's Hall is similar to the city hall, all orders are issued from here, and the branch halls in other cities will do the same in the future, so as to form a complete management system.

Steelmaking has been successful, followed by copper smelting and electrosmelting aluminum, one for the production of bullets and one for light materials.As for the two-acid factory, there is no rush for the time being. Dugu Yan seems quite talented, and with Dugu Bo, he should be able to handle the laboratory production of the two acids easily. As for the industrial production, there is really no rush.

As for the special alloy for placing the ice and fire spring water, they can only try it slowly, and this is a product of luck.

After arranging the next development plan of Wuhun City, Tang Sangang returned to Notting City. After greeting his parents, he came to Notting Shrek Academy. Wang Sheng, A Fei, Zhang Wei and others naturally stayed after the academy was upgraded to the Advanced Soul Master Academy.
"How are you doing recently? It feels like I haven't seen you for a long time." Tang Sangang asked with a smile,

"That's right, since Miss Xiaowu stopped beating people, Boss Tang's actions have gradually decreased. Naturally, he seldom sees us." Wang Sheng smiled innocently. He was already 21 years old. The three bars are raised by one shoulder.

"As for the college, it's a good life. Everything is free. You don't have to worry about food or clothing, and you can study hard."

"But Miss Xiaowu seems to be beating people up again recently..." Zhang Wei mumbled to the side,

"Emmm, she has returned to her original nature a bit, but is that Xiao Wu beating someone? That's a sparring! I think you guys dare to tell the truth without being beaten for a few months, right?"

The three of them shook their heads and waved their hands, "No, we miss the days when we competed with Miss Xiaowu, hehehe..."

"Huh? Nothing, meaning it's all lies?"

"It's the truth! It's the truth!"

Tang Sangang smiled slightly, teasing them occasionally, feeling as if he had returned to those carefree days.

"Hey, I won't argue with you anymore, what about the rest of Qishe?"

"Some of them have gone home. In the past few years, they have earned enough gold soul coins by being beaten by Miss Xiao Wu... the money from laning competitions, and making black soap at home, so they dropped out of school and went back to start a family. There are also some Some people went to hunt and kill spirit beasts, and never came back... and some people left, as if they had disappeared from the world, and they were nowhere to be found."

Tang Sangang was silent, just like in his previous life, there were only a few of his classmates who could still be contacted after graduation.It is also normal for accidents to occur when hunting soul beasts.

"Hey, let's not talk about this, by the way, how many levels do you have now?"

"I'm level 23," Wang Sheng replied,
"Me too," Ah Fei said with a smile, scratching his head.

"I'm only level 17," Zhang Wei said awkwardly, even the original fool Wuxuan had level 18, his talent was really too low.

Remember his crayfish spirit?
The first soul ring is ten years white, and the soul skill is paralysis.Crayfish's attack comes with a paralyzing effect, but looking at the crayfish walking unsteadily, it feels like Wuhun himself has been paralyzed. Tang Sangang's eyebrows twitched. Could this guy find a prickly ash tree to get a soul ring? Let's find another chili seedling, and this spicy crayfish is ready.

The attack power of the soul beast is still about zero, but Zhang Wei let go now, slowly accepting the suggestion that he is about to become a food-type soul master.

Tang Sangang patted several people on the shoulders, "Cultivate hard, and try to graduate before reaching the age limit. The world outside the academy is very big. We won't stay in the academy forever."

Not all soul masters in this world can graduate smoothly. There are many mediocre ones. When they reach the age of 25 and have not reached level 30, they will naturally be expelled from the academy.

"Yes! Boss Tang!"

The faces of several people were filled with sincere smiles. The best years were always the time in school, but unfortunately, many people didn't cherish it, and didn't realize this truth until they left there.
