In fact, before the industrial revolution, the development of the global metallurgical industry was limited by the temperature of fuel combustion.
Within the allowed range, the higher the controllable temperature, the easier it is to smelt iron and steel.
The key reason why Feng Yong can guarantee that he can use charcoal to smelt good iron is that he knows a way to increase the temperature of charcoal when burning in the forge.
That is to add a blower to the iron smelting furnace.
I remember that when history books talked about the history of Chinese metallurgy, they said that the handicraft industry in the Song Dynasty was particularly developed. What impressed Feng Yong most was the illustration on that page, which showed a man pushing and pulling a blower.
The explanation in the book is that the blower can increase the temperature inside the furnace.
When he was working on coke, Feng Yong wanted to get a better blower, but unfortunately the time was too tight. He had to design, test, and even improve the furnace to see how to match the blower...
He is not an almighty superman, how could he possibly be able to take care of this?
In the end, a few small test machines were built.
So this is also the reason why he can only build thirty sets of armor - the efficiency is too low.
Anyway, I don’t intend to make money by smelting iron. With this method, I just hand it over and there is no loss.
As far as the current requirements of the Prime Minister of the Han Dynasty are concerned, he only needs to produce good iron. As for production efficiency, he does not have many requirements for the time being.
Solve the problem of whether or not first, and then you will think of how many problems there are.
A way of thinking that is very characteristic of the Chinese nation.
Feng Tubiao felt at ease and wanted to be lazy.
As for when the day came, the Prime Minister of the Han Dynasty suddenly discovered that charcoal restricted iron smelting too much. If he wanted to produce refined iron better and faster, his eyes would naturally fall on coal. At that time, I made a profit just by selling coal and coke.
Big hair!
I handed over the methods for smelting refined iron to the country...well, to the imperial court. You are embarrassed to come and rob my coal mine again, right?
If you dare to grab it, I will rope in the queen!
If that doesn't work, just tell the old demon Zhuge and tell him that there is coal all over the ground in Nanxiang. If you are willing to put in the effort to look for it, you will definitely find it.
Nanxiang is so big that it includes two counties in later generations.
With the current level of technology and the few manpower, it would take decades or even hundreds of years to dig out all the resources.
After a few decades, either the big man is gone, or I am gone, who can care about what happens afterward?
It would be even better if the ideal of the Prime Minister of the Han Dynasty to return the old capital could really be realized - if he really wanted to return the old capital, who would care about this bit of coal in Hanzhong? Guanzhong is full of it all over the world!
"How can you refine refined iron from ordinary iron stone using charcoal?"
Seeing that Feng Yong was willing to reveal his master's secret skills, Pu Yuan asked impatiently.
"Oh, this is simple. To smelt refined iron, you either need to find high-quality iron stones, or you need to heat the iron furnace... um, um, think of a way to make the fire in the furnace hotter."
It is often said that China has a vast territory and rich mineral resources, but there is a sentence behind it that is often ignored.
That is, there are many poor ores, few rich ores, and many associated ores, which brings many difficulties to smelting.
So it is difficult to find high-quality iron ore.
China began to enter the Iron Age during the Spring and Autumn Period and the Warring States Period, but to fully replace bronze wares with iron wares, we had to wait until the Han Dynasty.
Unfortunately, due to the limitation of forging temperature, the improvement of smelting technology has been very slow.
Therefore, the current level of iron smelting can only be regarded as preliminary or even primitive. It is not too difficult for Feng Yong to improve the iron smelting furnace.
The difficulty lies in producing high-quality iron in large quantities.
It is not difficult to add a blower. The difficulty lies in how to add a large blower to improve production efficiency.
"How to burn?"
When Pu Yuan heard this, he finally believed that Feng Yong could really smelt iron.
Even if you want to smelt good iron yourself, you can only find a good iron mine, and at the same time pay attention to the quality of the water for quenching the iron, but how to make the fire in the furnace burn hotter is not clear.
"I can't say it in words. I'll draw a picture for Madam later."
The stingy Feng Tubiao still remembered what Pu Yuan had just accused him of, but he deliberately did not tell him.
The most important thing is that Feng Yong also thinks that since Huang Yueying has studied the book "Lu Ban Jing", then the craftsmanship should be good. Legend has it that Zhuge Lao Yao's inventions in history are inseparable from Huang Yueying, and now it seems that it may not be the case
real.
Give her this blower, what if she can improve it to what she wants?
Isn’t that supposed to be fun?
This woman... to be honest, she is really a top-notch woman.
Zhuge Lao Yao's good fortune...can't be said.
Feng Tuchel was thinking wildly when Huang Yueying turned her head, nodded gently to Zhuge Liang, and then turned to look at him lovingly, with joy at the same time.
"Okay, then I will wait for you to draw it. It has been delayed for a long time, so I won't bother the Prime Minister to ask you anything."
With that said, he stood up and walked out.
Seeing this, Pu Yuan had no choice but to reluctantly say to Feng Yong, "Feng Langjun, after you finish talking to Kong Ming later, don't forget this matter."
Then he and Huang Yueying walked out one behind the other.
Looking at the plain face of Old Demon Zhuge who was sitting on top, Feng Yong suddenly understood. It seemed that three people had plotted against him?
Just for the secret of armor and weapons made of fine iron?
As for what?
"Did you see it?"
As Zhuge Liang was the first person under the Han emperor, Feng Yong's change of mind naturally could not escape his notice.
It's just that the Han Dynasty Prime Minister has magnanimity after all. After seeing the two people go out, he admitted openly and openly, "I won't hide it from you. Ever since Pu Yifan heard that you have armor and weapons made of fine iron in your hands, I am extremely worried."
It’s curiosity.”
He sighed and said, "Over the years, he has been entrusted by me to find iron smelting places that can make high-quality weapons. Unfortunately, he has searched all over Shu, but there is no place where he can be with the late emperor.
Compared with the Taurus Mountain at that time.”
"I thought this would be the end of it, but I didn't expect that God bless the man, I would see such fine iron on your hand again, so I had to test it with you."
"Cao's thieves are so powerful that they occupy the heart of the Central Plains, which cannot be matched by the Han Dynasty who only relies on one side. Therefore, if he wants to revive the Han Dynasty, he has to use some extraordinary measures."
It's understandable. I also know that you invented a lot of things later.
"In the past two years, I have taken something from your hands, and I will remember it in my heart. Whether you complain or hate it, it is all my fault, but there are some things I have to do."
"I just hope you can understand a little bit because the big man is so weak."
Seeing Zhuge Liang sitting above speaking these words calmly, and looking at his face again, it seemed that he was a little older than he had been two years ago.
I don't know if it was because the light was too dark to see clearly, but Feng Yong always felt that his temples were a little gray.
His heart softened, Feng Yong said, "Yong is a citizen of the Han Dynasty, and he must do his part for the Han Dynasty, so the Prime Minister does not have to worry about it. After all, in the past two years, although the Prime Minister has taken away a lot of things, but
I also gave a lot of things, which is enough.”
Although the old demon Zhuge kept yelling at him, Feng Yong still knew that the great Han Prime Minister had been indulgent and tolerant enough towards him.
And he also gave himself a lot of help secretly.
Besides, reviving the Han Dynasty was almost his entire belief for the rest of his life.
For the sake of his faith, he can even give up his own property and life. What else can you do to him?
Even the emperor has to cower, how can a country bumpkin stand up under his hands?
So Feng Yong never had too many extravagant hopes.
Zhuge Liang nodded, "If you say it's enough, then I'll take it as enough. Anyway, the big man can't give you anything more now. If in the future..."
