Daqin: Zulong's Traveling Frog

Chapter 145
Iron smelting in the Qin Dynasty mainly revolved around skin bags, which were similar to wind blasts.

A support ring is installed inside the leather bag, and baffles are installed at both ends for air inlet and outlet.

The iron smelting method is roughly as follows: one person presses the bag in front of the bag to blow the air, and another person holds the bag under the bag to return it to its original position. Horses can also be used to complete the blowing action.

The development of iron smelting technology after the Han Dynasty naturally involved improving the skin bag to increase the wind pressure and increase the temperature of the steelmaking furnace.

The melting of pure iron requires [-] degrees Celsius, and even cast iron with impurities and high carbon content requires [-] degrees Celsius.

The tool that can significantly increase the temperature is naturally the use of the water row, which can significantly increase the blast volume and further increase the temperature in the furnace.

And the artifact that Xiao Zhinu brought back was naturally a water drain!

The water row is to change the human row that should have been pushed back to the original position by humans, or the horse row that was agitated by horsepower, and changed to the water row that is agitated by water power.

Water drainage was invented by Du Shi in the Han Dynasty, which was nearly a thousand years ahead of Europe. It pushed iron smelting technology to its peak and was more than 1000 years ahead of Europe.

During the Sui and Tang Dynasties, driven by water drainage, people successively developed cutting, polishing, welding and other processes.

Since the Song Dynasty, iron smelting technology spread in the Liao and Jin Dynasties and extended to Asia, Europe and Africa, influencing the development of iron smelting technology in the world.

Qin Wangzheng could see the value of water drainage at a glance, so he could call for "left mining iron" and "right mining iron" to promote this iron smelting technology.

[Note: Mining iron on the left and right are officials in charge of iron smelting in the Qin Dynasty]

But the left and right mining irons all frowned when they saw the water drain, a trace of surprise flashed in their eyes, and they said inwardly, "Has your majesty lost his mind?"

"Why use a toy to change the technology of iron smelting?"

"Should we drain the water into the furnace to fuel the fire?"

Thousands of absurd ideas flashed in the minds of the two of them, but they only dared to complain in their hearts but dared not speak out. Instead, with smiles on their faces, they asked: "Your Majesty invented an artifact that benefits the country and the people, is it true?" I am the blessing of Qin!"

"But iron smelting technology has used horse steak to eliminate human steak, and the effect is remarkable!"

"But I don't know what this thing is, can it significantly improve iron smelting technology?"

King Qin's face showed no joy or anger, his eyes were cold and he said: "Shui Pai!"

Zuo Yetie's face was shocked, and he swallowed his saliva and said: "Water row? Could it be water blasting?"

The water raft is different from the wooden raft they had in mind!
Since it is a water drain, why is there no water?
Could it be that a wooden tool similar to a wheel could be used to smelt iron?
No one will believe that a wooden frame can make full use of water resources, just like a horse or human platoon that can push a skin?
Qin Wangzheng didn't care about the stunned expressions of the two, but his eyes were fierce, with a murderous look in his eyes, and he said coldly: "What? Do you want me to demonstrate it to you?"

The two of them were shocked immediately, they were so startled that they couldn't stand their feet, they plopped and knelt down in the tunnel, "Don't you dare?"

Under Qin Wangzheng's sharp reprimand, the two left in despair.

Before leaving, I didn't even ask how to use the drain.

After stepping out of the main hall, Zuo Caitie wiped the cold sweat on his forehead with the corner of his clothes, just now Qin Wangzheng yelled loudly, scaring the two of them almost out of their wits.

Youcaitie just said weakly: "It seems that I can only study how to use the water drainage!"

After the two left, a trace of fierceness flashed across Qin Wangzheng's brows, and he summoned Qin Mo to go to the palace.

Different from mining iron left and right, Qin Mo changed from his previous negligence and became extraordinarily enthusiastic.

After all, Qin Mo went to the palace to meet Qin Wangzheng over and over again, and every time he got unexpected gains and invented new things.

Under Qin Wangzheng's whimsical thinking, it may seem absurd to others, but in Qin Mo's eyes, it is a tool with exquisite workmanship, which can spread the world and benefit the people.

Sure enough, after Qin Mo knelt down and saluted, Qin Wangzheng smiled slightly and handed the parchment to Tian Feng.

There was an indelible smile on Tian Feng's face, his expression was free and easy, and he said lightly: "Your Majesty, I will do my best!"

After Qin Wangzheng told them to build a hundred water drains, Qin Mo left with peace of mind.

Under the impetus of Xiaozhinu, another artifact that benefits the country and the people was born!
Hydraulic exhaust is enough to replace manual exhaust, making the temperature of the furnace enough to reach more than a thousand degrees, and this temperature is naturally the temperature at which cast iron is calcined.

After discussing and coordinating the iron mining, the water drainage was successfully applied to the iron smelting technology within three days, which not only saved time and effort, but also significantly improved the efficiency of blowing.

In the iron smelting workshop, Qin Wangzheng issued an imperial edict ordering the left and right mining iron to be calcined together with the Qin craftsmen!
As the Qin Dynasty, which transitioned from bronze ware to iron ware, can it also build a strong bow and crossbow like South Korea?

Could the soldiers of the Qin Dynasty also wear iron helmets, wear iron armor, and hold iron swords?

If this is true, then wouldn't Great Qin's million-strong army be invincible and wipe out the Eurasian continent in one fell swoop?
Sure enough, after a hundred days of calcination, a new iron tool was born.

The soldiers in charge of guarding the blue sky camp put on their battle armors, and the armors glowed brightly under the stimulation of the cold wind.

Qin Wangzheng couldn't help but sigh with emotion: "Little Zhinu's forging method is really unique, enough to match the toughness of South Korea."

Qin Wangzheng also saw with his own eyes the newly built crossbow. With the use of water rows, the iron crossbow was able to shoot [-] steps, which was enough to match South Korea.

Forged farm tools are also far harder, more durable, and sharper than bronze farm tools!
The left and right mines are jaw-dropping, and it is unbelievable that a slight change in water drainage can forge iron.

Bronze smelting lasted hundreds of years and reached its peak in the Spring and Autumn and Warring States Periods.

Compared with ironware, there are countless disadvantages.

However, the iron smelting technology in South Korea and Chu State is not mature. It is nothing more than using natural iron ore and calcining it in the furnace according to the bronze standard.

But this is the first time I have heard of smelting iron!
Among the weapons of the world collected by the Qin Dynasty, the Korean ironware can be directly calcined into molten iron and recast.

The bronzes have no use value, so it is natural to cast them into twelve bronze figures.

"Smelting and opening the furnace—" When Qin Wangzheng's edict flew back to Xianyang, Zhang Han jumped up and roared.

When the autumn wind came in the second year, the copper and iron weapons finally turned into twelve huge golden men, standing in two rows on the square in front of Xianyang Palace.

Each golden figure is five feet six feet high and weighs 34 catties. It is golden and gives a bird's-eye view of the carriages, horses and pedestrians. Its power far exceeds that of the three generations of Jiuding.

Qin Wangzheng looked at the twelve bronze figures displayed outside the palace gate, and his heart hanging in the air finally dropped.

But living in the palace for a long time is unavoidably boring, so it is better to go out for a walk and see how colorful the outside world is.

With the tacit approval of all officials, Qin Wangzheng is finally going to conduct his first nationwide tour
ps: Staying up late to catch up on the draft was successful!
