Chapter 184 Thanks for the Nine Years of Compulsory Education
Chapter 184: Thank you for nine years of compulsory education
"Sir, is this the concept of pig iron and wrought iron you mentioned?"
Lu Lingqi gently tapped her forehead with her delicate hands. During this period, Yi Xiaotian had instilled so much knowledge about the "Steel Filling Method" that she was a little dizzy...
However, she liked this forging process very much and was looking forward to it... looking forward to seeing another failure in forging steel and her husband's deflated appearance.
"Haven't you tested it many times before?"
Yi Xiaotian waved his hand, and naturally a craftsman took out the iron that had been filled with steel from the furnace.
"You girl, I've told you this so many times that I can't even remember it."
Yi Xiaotian explained repeatedly. "After the iron is melted, carburizing liquid will be formed. This carburizing liquid will penetrate into the wrought iron. The wrought iron will become stronger due to the penetration of carbon and become steel. Pig iron will become steel due to the penetration of carbon.
Decarburization will also turn it into steel, which is the so-called steel filling method!"
Yi Xiaotian is teaching Lu Lingqi very carefully...
Lu Lingqi looked a little dizzy. It wasn't that she couldn't listen. She recognized this method as cocoon, but the results were very sad. So far, the husband has not succeeded even once!
Speaking of which, this knowledge of "steel filling" is actually very professional.
Yi Xiaotian only studied the rise of the forged steel industry in the Wei, Jin, Southern and Northern Dynasties in the process of studying history, and went to learn more about it.
The specific principle of steel filling is nothing more than that the chemical elements such as carbon, silicon, and manganese in the pig iron react with the oxides in the wrought iron at high temperatures, thereby achieving the effect of removing impurities, purifying the metal, and improving the quality of the iron.
It was naturally tempered into steel.
But the principle is this, but in practice... there are still a lot of problems.
For example, how to determine the carbon content of iron?
What is the ratio of pig iron to wrought iron?
Are there any requirements for the quality of iron?
There is also the use of coal in the steelmaking process...every point is a problem and requires repeated trials.
Just for this reason, Yi Xiaotian and Lu Lingqi have been practicing for less than half a month, but they still have no success.
"Sir? How reliable is your steel filling method?"
Lu Qiling pursed her lips... "We have spent a lot of money in the past half month. The craftsmen are all tired and sweating profusely. But what are they making? Not to mention it is stronger than iron.
It’s hard to make anything half as hard as iron ore…”
Speaking of this, Lu Lingqi looked at Yi Xiaotian eagerly. "Sir? No matter how rich you are, you still don't spend your money like this? Otherwise, let's forget it...Sir, don't waste gold like this."
What Lu Lingqi said is true. The price of iron and steel is now comparable to that of gold. Yi Xiaotian here looks like he is making iron, but in fact he is just throwing boxes of gold into the furnace. The key is to throw so much money at it.
When you go out, you won’t even get a chance!
"Shut up…"
Yi Xiaotian directly covered Lu Lingqi's small mouth. "You're so brave, aren't you? Do you dare to scold Mr. Qi?"
This girl hasn’t been taught a lesson for three days. “There is plenty of money here, sir. You can spend it as much as you want. The so-called rich people are willful, but you, if you don’t have money, just accept your fate, talk less and do more business!”
"
"Humph!" Lu Lingqi pursed her lips, with a hint of resentment in her tone. "I would like to see when Sir can refine this steel."
But at this moment...
The sound of "tap, tap, tap" footsteps came from outside the blacksmith shop. Cao Cao and Cao Ren quickly walked into the blacksmith shop...
When they arrived at Youjian Villa, they went to the wine shop first. After talking with Cai Zhaoji, they found out that Yi Xiaotian was at the blacksmith shop now, so they rushed over without stopping.
However, at this time, Yi Xiaotian and Lu Lingqi were still bickering, but they did not notice their presence.
"Brother... let's..." Cao Ren planned to call Yi Xiaotian. After all, they were also in a hurry... The battle on the front line cannot be delayed.
"I'm not busy." Cao Cao stopped Cao Ren. "Don't spare Brother Yi's interest. He was having a great time playing with that little girl..."
In Cao Cao's view, the battle on the front line is indeed important, but it does not care about this moment.
Last time, he disturbed Brother Yi's play with the beauty. This time, he was embarrassed.
Simply stand here and wait patiently for a while.
at this time.
A big man in the blacksmith shop shouted, "It's done, it's done!"
Then countless people quickly gathered around.
Yi Xiaotian and Lu Lingqi also came over.
Cao Cao and Cao Ren noticed that there was a piece of iron covered with flames and glowing white on the iron table...
No, to be precise, it cannot be called iron. It has a texture that is stronger than iron. The texture of this stone is somewhat similar to the material of the Yitian Sword on his waist.
At that moment, Cao Cao was even more curious and hurriedly approached...
…
"Is it done?" Before the iron case, Yi Xiaotian looked a little excited.
"It's done, Shopkeeper Yi, we have really made it." The craftsman explained while pointing to the stone made of iron. "Look, this texture and texture, this is hundred-refined steel.
!”
With many years of experience in blacksmithing, he could tell at a glance that the piece of iron that had been filled with steel was very different from ordinary iron...
Admittedly, they had failed countless times before in pouring steel, and the coins consumed were measured in the millions.
It is precisely because of this that they will become more diligent and proficient every time they practice steel.
Now that we are done, how can we not be excited?
At this moment, Lu Lingqi's eyes widened, and she was carefully observing this so-called "hundred-refined steel".
In this era, the so-called hundred-refined steel, according to records... cannot be artificially forged.
Most rumors are about meteorites landing and justice coming from the sky...
In fact, to put it bluntly, it is not that fantasy.
In fact, a fire burned a mine that was deeply buried in iron and steel. The high temperature melted the iron and iron on the surface and penetrated into the iron and iron at the bottom. Therefore, by chance, hundreds of refined steel was made.
The Yitian Sword and Qingzhi Sword in Cao Cao’s hand;
Sun Jian's ancient ingot sword, Lu Bu's Fangtian painted halberd;
Liu Bei's male and female double-pronged swords, Guan Yu's Qinglong Yanyue Sword, and Zhang Fei's Zhangba Snake Spear are all forged from this highly refined steel.
Precisely because this hundred-refined steel is rare and non-renewable, it is simply priceless and unavailable on the market... no matter how wealthy you are, you may not be able to buy it.
As for Yi Xiaotian's blacksmith shop, it was the first time that anyone could forge hundreds of refined steel.
"Sir, it looks like the texture is really refined steel. Isn't it... really made?"
Lu Lingqi's big eyes blinked continuously, she was a little confused...
After half a month of continuous failure, repeated defeats, repeated defeats, she was almost discouraged. Her husband's steel filling method was really successful. This...
Lu Lingqi was suddenly a little excited.
Compared to her excitement, Yi Xiaotian seemed very calm and didn't make any fuss. After all, his guidance was in the right direction.
Of course, there are still many coincidences involved in the success of steel pouring in the blacksmith shop.
Here, except for Yi Xiaotian, everyone will definitely not consider the scientific principle of c + o2 = co2 in chemical elements.
Not to mention that fe (iron) contains s (sulfur);
Not to mention that once it is ignited and reaches the boiling point, the chemical reaction of s+o2=so2 (sulfur dioxide) will occur.
It is precisely this so-called sulfur dioxide that penetrates into iron and can dissolve the impurities in it, turning the iron into harder steel.
As for the principles of sp (hot brittleness and cold brittleness), solid solution strengthening, and secondary strengthening, which are also involved, these are even more complicated.
However, these are not important anymore.
Yi Xiaotian was stunned to rely on the knowledge in his mind and actually put the steel filling method into practice with the hands of Lu Lingqi and a group of craftsmen.
For a moment, he was very grateful...for the nine years of compulsory education he received before time travel. Sure enough, compulsory education is very good and powerful!
Calm on the surface, ecstatic on the inside.
Yi Xiaotian knew that from the moment steel appeared in this era, there would be no absolute fairness in the cold weapon battlefield...
It's like steel is ten times harder than iron. When an iron army faces a steel army, it's like an elephant on an ant day - they can't use their strength!
Yi Xiaotian felt a sense of despair. He couldn't even think about how much money he could make from this thing.
But at this moment.
"Brother Yi? What is this? Are you all ecstatic?"
A crisp and familiar voice came one after another. Yi Xiaotian looked back and saw that the person standing behind him was not Brother Hao? Who else could it be?
