Hu Changan smiled slightly and said: "I think we can raise the height of this furnace and blow in hot air, so that the efficiency of ironmaking can be accelerated."
What?
Raise the furnace and blow in hot air?
Everyone was a little confused.
These two methods are completely unfamiliar to them.
Ma Shi was the first to step forward and asked, "Shilang Hu, I wonder what the purpose of using these two methods is?"
At this time, Ma Shi had already shed his previous aloof demeanor.
Now Ma Shi can be said to be extremely humble and could not be more humble. He was close to enshrining Hu Changan.
When Hu Changan heard Ma Shi's question, he smiled slightly and said, "The reason for using blast furnaces to make iron is so that the iron ore can fully react with the particles in the air."
"We can load raw materials such as iron ore and coke into the blast furnace from the top, and use a hot blast stove to blow hot air into the blast furnace from the bottom to help the coke burn."
"After coke reacts with a particle in the blown air, particles that can react with iron ore can be obtained."
"When the raw materials settle in the blast furnace, they meet the rising gas and react to produce pig iron."
After hearing this, Ma Shi was also a little confused.
He never thought that raw materials could be sprinkled in from the stove, nor did he think of blowing hot air to help production.
However, after Hu Changan's miraculous display of skills just now, all the craftsmen highly praised Hu Changan.
Even though they didn't understand it, it didn't stop them from trusting Hu Changan.
Thus, the renovation of the iron-making furnace of the Ministry of Industry was finalized.
Hu Changan handed the pre-drawn design drawing to Manager Jiang and walked out of the workshop.
It's not too early now, it's time to go back home and prepare for coal mining.
Hu Changan took a leave of absence from Xue Xiang, Minister of Industry, and rode back to his residence.
There is peace in Hu's mansion.
Seeing that the young master was back, everyone bowed and bowed.
Hu Changan hurriedly nodded to these servants and called Manager Chen in.
"Manager Chen, please come with me to the dental shop."
"yes."
So Hu Chang'an and Manager Chen rode their horses towards Yahang again.
In the tooth row, there is still a familiar lively scene.
This time when the boy at the dental shop saw Hu Changan, he was obviously much more enthusiastic than before.
Who is doing business in Yingtian City now who doesn’t know the famous name of Hu Mansion?
I earn twenty thousand taels of silver a month!
This is a number that no one dares to imagine. I didn’t expect that Hu Changan actually did it!
Everyone can only lament that the future life is terrible.
Hu Changan waved his hand towards the boy and said, "I wonder if there is any land for sale in Gaochun County?"
"Hey, there are some." The boy said enthusiastically, turned around and took out a large map, which marked in detail all the land that the dental store was selling for Hu Changan to choose from.
Hu Changan also sat down unceremoniously, took a sip of tea from Yixing, and carefully selected it.
Before coming, Hu Changan had already redeemed the "Daming Coal Mine Encyclopedia" in the system.
Today's Hu Changan has no shortage of points of admiration at all.
With a large amount of worship points coming in every day, Hu Changan has long been numb to numbers.
For things like books, I basically just buy them casually.
In the "Encyclopedia of Daming Coal Mines", every place with underground coal mines is marked in detail.
Unfortunately, the south is not a coal-producing area, and there is only one small coal mine in Gaochun County.
But for Hu Changan, this was enough.
After all, the Ming Dynasty's industrial system has not yet been fully established, and the amount of coal used is very small. A small coal mine is enough to solve the urgent need.
Hu Changan looked at the map and compared and selected carefully.
Finally, Hu Changan was overjoyed.
found it!
Unexpectedly, where the coal is located, there happens to be a barren mountain!
Bought, bought.
Hu Changan did not hesitate to call the boy to come and pay.
After the signatures and paintings were signed, Hu Changan had another barren mountain in his name.
The boy looked at Hu Changan's look, quite puzzled.
This barren mountain has been on the market for several years without being sold.
There are no villages nearby, and it cannot be planted. It is just a large area. It is simply a piece of tasteless food that is a pity to throw away.
Unexpectedly, it was bought by Hu Changan.
Recalling that Hu Changan also bought a piece of wasteland before, the boy couldn't help but think about it.
Could it be that this is the secret to the success of the boss?
The boy quickly revealed the news to his colleagues.
Soon after, a small-scale craze for buying wasteland started among the merchants in Yingtian City.
But at the moment, Hu Changan has no idea about the farce he has caused.
After getting the land deed, Hu Changan ordered Manager Chen to quickly mobilize some strong men to open up wasteland in the newly purchased hill.
...
The next day happens to be a rest day.
Hu Changan led a group of tall men to a hill in Gaochun County.
When everyone saw this, Monk Zhang Er was simply confused.
Why did Master Hu bring them to such a remote place? Do they want to open up wasteland here?
An experienced man glanced at this hillock and frowned slightly.
The soil quality on this mountain is really not very good.
Not only is it impossible to grow rice and wheat, but it is also difficult for even the best fruit trees to take root on this hill.
Master Hu, are you going to let them plant things on this mountain?
What a waste of time!
It seems that Master Hu is still too young. He was defrauded of money and bought a small hill where nothing can be planted.
However, Hu Changan didn't know what everyone was thinking.
Hu Changan jumped off his horse, took out a shovel from the truck behind him, and said to everyone: "Everyone, please dig the mountain here in the next few days."
"There should be something dark that can be dug out of this mountain and can be ignited with fire."
"If you can't dig on the ground, you can choose to dig deep in the cave."
At this time, everyone was shocked.
What?
Master Hu actually asked them to dig something?
Can black combustible materials be dug out of the soil? Isn’t this ridiculous!
One bold man even said directly: "Master Hu, are you kidding us? How could you dig something like this out of the soil?"
"And the mountain is so big, it's not a problem for us to dig down aimlessly like this!"
After hearing this, Hu Changan just smiled slightly and said: "I said it can be dug out in the mountain, then it can definitely be dug out. You don't have to worry about this."
"I will send someone to supervise the work. As long as you are not lazy, I will give you one day's wages for every day of digging. Just dig."
Hu Changan was powerless to deal with this problem of men.
The map only told him that there would be coal in this mountain, but it did not tell him where exactly the coal was!
The only thing we can do now is send more manpower and start digging first.
