Peek at my diary, Cao Cao dominates the Three Kingdoms

Chapter 574 The Steelmaking Plant Seeing First Results
Xu Shu stayed in Jingzhou for many years when he was studying, and he is very familiar with the situation in Jingzhou.

Lu Yan and Xu Shu had an in-depth conversation on a series of issues in Jingzhou, which benefited Lu Yan a lot.

Xu Shu is worthy of being Sima Hui's master apprentice, with sharp and unique insights; but compared to Xu Shu, Lu Yan knows more information from later generations, so his views are more comprehensive and in-depth, which also makes Xu Shu's heart against Lu Yan. Yan is completely convinced.

The two chatted happily, and Xu Shu also stayed in Hushi General's Mansion for three consecutive days.

But it was a pity in the end, Xu Shu said that he would go to Hebei to see again, so he declined Lu Yan's invitation to become an official for Xu Shu on behalf of Cao Cao.

In the seventh year of Jian'an, in April, Gan Ning married Zhao Xue, Zhao Yun's righteous sister, and the wedding ceremony was lively and sensational.

In the seventh year of Jian'an, in June, Xia Houlan married Zhen Rong, the fourth daughter of the Zhen family.
In just half a year, several generals and scholars under Cao Cao and Lu Yan chose to marry, which is also a concrete manifestation of the stability of the people.

After nearly half a year of difficult times, the iron and steel plant in Dai County finally began to operate normally with the full support of Tian Chou.

Lu Yan traveled thousands of miles to Dai County, in order to see the situation of the ironworks with his own eyes so that he could feel at ease.

After seeing the steel factory, Lu Yan thought to himself: "Although the scale of the area is far smaller than that of later generations, it is undoubtedly the top existence in this world." He is undoubtedly satisfied with the current scale.

"The iron mine with the richest resources is located in the deep mountains, and only a small part is exposed, most of which are buried under the soil, so it is not easy to mine."

"We have now organized more than 21 Wuhuan captives to mine iron ore in the mountains, and built [-] shafts, four sideways, and one open-pit mining pit. Now we are basically on the right track."

"It's just that the transportation of iron ore is a big problem. Due to the difficulty of the mountain road, we have to adopt the method of manpower. This leads to a decent mining volume, but only about one thousand catties of ore can go out of the mountain and enter the steelmaking plant every day. "

"Also, if it rains in the forest, the road will be extremely muddy"

Lu Yan, accompanied by Ma Jun and several assistants, inspected the newly established steel factory, and Ma Jun's assistants took turns explaining their current situation and the troubles they encountered to Lu Yan.

"There is only about one thousand catties of ore a day." Lu Yan frowned. This efficiency was completely unacceptable to him.

The bottleneck of the iron and steel plant today is the transportation efficiency of iron ore. To increase the speed of ironmaking, it is necessary to find a way to improve the current transportation method that relies solely on manpower.

mode of transportation.
To be honest, after all, he is someone who has experienced the baptism of the information explosion in later generations. When it comes to improving the transportation method, countless plans flashed through Lu Yan's mind in an instant.

After comprehensively considering the environmental issues such as mountain forest paths, Lu Yan felt that there was only one thing that was most suitable, "unicycle!"

Lu Yan turned to look at Ma Jun's deputy, and said, "Prepare me a pen and paper, I may have a way to relieve the pressure of transportation."

"Ah?! Is there a way?" the deputy said to himself in a daze.

"Hurry up!" Ma Jun kicked the man, and said with hatred, "Lu Huss and Hussars say yes, then there must be!"

"Yes, the little one will go right away!"

The man left quickly, and came back in less than twenty breaths, with a large piece of snow-white paper and pen and ink already in his hand.

Lu Yan picked up the brush on the table, and quickly drew what he just sketched in his mind on the paper.

But Ma Jun and his assistants tilted their heads, staring at a strange thing that appeared in Lu Yan's pen.

After Lu Yan put down his pen, a deputy asked curiously: "Lu Huanqi, what is this painting you painted? Why does the car only have one wheel?"

"Indeed, this is what I just came up with, a unicycle." Lu Yan explained to Ma Jun and others: "The frame can be directly installed on both sides of the unicycle, and only one person needs to hold the two handlebars from the back. It can be carried out.”

"Does this seem feasible?"

"The single wheel makes it more flexible, but I don't know if it can move forward in the mountains and forests."

"I don't know how much I can carry"

Ma Junben is a master of machinery. He knew immediately after seeing the wheelbarrow that it could indeed relieve the pressure of transporting iron ore to a certain extent.

Seeing the people around talking about it, Lu Yan continued, "Because this kind of small car is on the ground with one wheel, it can travel unimpeded no matter whether it is a plain official road or a mountain trail. It is definitely better than manpower carrying or carrying a basket."

"The unicycle is good, but...but we'd better... open up a road."

"That's right, the road must be built. But we can do these two things at the same time, and those Wuhuan people can't waste food for nothing."

"Of order!" After Ma Jun accepted the order, he turned his head and said to his deputy, "Go, find, find two people to try, and first build Lu Piao Huqi's unicycle."

The assistant picked up the drawings drawn by Lu Yan, nodded hurriedly and said: "We have many skilled carpenters here, I will go find them now!"

The assistant asked someone to make the wheelbarrow, while Lu Yan, accompanied by Ma Jun, went to the factory building to inspect a series of equipment such as the steelmaking furnace.

In the past, the furnaces used for steelmaking by pouring steel were all small furnaces about the height of one person. Although the quality of the steel produced was very good, the efficiency could not keep up with the current demand after all.

When he came to the iron-making area, Lu Yan saw an unusually tall earthen blast furnace in front of him at a glance.Not far from both sides, there are two blast furnaces under construction.

The principle of blast furnace smelting is actually relatively simple. The main thing is to send iron ore, coke and limestone into the blast furnace in batches. It is gradually reduced and melted in the blast furnace, and finally molten steel flows out from the furnace mouth.During this period, with some experience and operation of the steel pouring method, the final steel quality can be made better.

Lu Yan came at the right time, and several craftsmen covered in sweat were about to release molten steel.

With the yell of the craftsman, the valve was slowly opened.

The golden-red molten steel flowed along the valve into the prepared trough, and meandered into the prepared molds everywhere. The eyes of the craftsmen around were shining brightly.

There were even two blacksmiths, who couldn't wait for the molten steel in the mold to cool, so they picked up the big hammer and started beating with their bare arms.

"Qi Qi reports to Lu Huanqi, with one furnace of molten steel, we can produce [-] catties of steel!"

A furnace of [-] catties is really terrifying!
You know, in the past, [-] catties of iron was enough for a prince for several years. After all, most of the soldiers under the princes only wore leather armor.That is to say, Boss Cao became rich and powerful with the support of the general supervisor, and equipped every soldier with high-quality weapons and iron armor.

But at this moment,
There was a sudden commotion outside the iron and steel plant, "A military aircraft important place, do not trespass!"

"Didn't you see that the governor is here?"

"Without a seal, no one can enter!"

"Hey! You have no eyesight. My old Zhang likes it! Hahaha!"
