When taking stock of Ming Taizong at the beginning, Lao Zhu was stunned!

Chapter 76: There is no place in the world that cannot be obtained!

Han Dynasty, the fourth year of Yuanshou.

Liu Che was extremely proud, this was his big man!
Although it is difficult to popularize hundreds of steel, there are still many people in this big man who are proficient in it!
As for the method of frying steel, it is now also widely spread among the people of his Han Dynasty!
The reason why Liu Che's army was able to continuously attack the Xiongnu was not only due to the family wealth accumulated by many previous emperors to recuperate and recuperate, but also had a lot to do with the large number of high-quality weapons and armor produced by this advanced steel-making technology!

It's a pity that he couldn't understand the oxidation and carbon, manganese, etc. just described by the miracle. He didn't know what oxidation was?

Then he thought about a talented person named Du Shi, but he had no impression of it before!

Now this person may not be famous yet, so he didn't know it, so he immediately waved his hand and sent someone down to look for him.
-
Tang Dynasty, the third year of Zhenguan.

Regarding the words praising their Tang Dynasty in the miracle, everyone either laughed on their faces, or they were secretly proud of themselves.

Changsun Wuji first woke up from his pride. He was not happy now. They did not understand the carbon and steel described in the miracle just now.

Could it be a secret of this industry?

Although they have never seen it, they understand most of the situation. According to the miracle, carbon exists in iron!
That's something to burn for warmth!
Why is it in iron!

Moreover, it seems that as long as the carbon is reduced, the iron will be better. What is the principle of this?

His keen intuition told him that it seemed that this was the principle that made the Tang Dynasty's technology a step further. If he could delve into it and understand it, the Tang Dynasty would complete the expansion overseas as mentioned in the previous miracle!
[As early as the Northern and Southern Dynasties, the steel-filling method appeared. As iron utensils became popular in all aspects of life, ordinary people's demand for iron was also increasing, so the steel-filling method came out. 】

[The steel-filling method is also called the group steel method and the raw and cooked method. Therefore, the steel-filling method is divided into pig iron and wrought iron. 】

[To make the pig iron is to put the pig iron at the mouth of the furnace. As the temperature continues to rise, when the pig iron begins to melt, use the tongs to clamp the pig iron plate and keep moving it left and right, turning it, so that it is extremely evenly mixed with the wrought iron, and finally becomes a mixture containing Steel with extremely low carbon content and very few impurities. 】

[The emergence of the steel filling method is an extremely important progress in the history of Chinese iron smelting. 】

[The operation method is simpler than the steel forging method. The blacksmith only needs to master the melting and proportioning of pig iron and wrought iron to produce steel with different carbon contents to meet the needs of different environments. 】

[At the same time, this method is cheaper and more efficient, and the steel produced is far superior to previous methods in terms of quality and quantity. Therefore, it has become the main iron smelting method, and the main method of all subsequent dynasties. One of the railway lines. 】

[And this also became the key to vigorously cultivating cavalry in the Sui and Tang Dynasties. 】
-
Ming Dynasty, Hongwu 13th year.

Everyone has known the steel filling method for a long time. They did not care about the so-called steel filling method, but noticed that "the steel filling method can produce steel with different carbon contents! To meet different needs."

Prince Zhu Chigao spoke first: "That is to say, the steel knives, iron swords and other iron items we use contain carbon used for fire and heating!"

But why does it contain carbon?
It doesn't matter if you don't mention these.

According to Miracle, steels with different carbon contents are also different and can meet different needs. In other words, they each have their own advantages!
Zhu Zhanji, the youngest of the generation, watched his father finish, and then added: "Fry the pig iron to maturity according to the steel-frying method mentioned before by the miracle, and the carbon content will be reduced."

"That is to say, the carbon content in pig iron is high. After being heated into wrought iron, the carbon content is low. In other words, heating can reduce the carbon! Just like after we burn the carbon, it turns to ashes and reduces! But What’s the use of this?”

The generals below have been exposed to armor for many years and are more familiar with it.

Fu Youde replied: "Your Highness, wrought iron is easier to deform and has a softer texture, but it is not easy to break when it encounters a violent blow. Although wrought iron is very hard, if it is used as a slender weapon, it will be easier to break." It broke when fighting with the opponent." In this way, everyone in the hall understood.

In other words, the higher the carbon content, the harder it is and the easier it is to break under external force.

The lower the content, the more tough it is and the less likely it is to break, but it is also softer.

Just when everyone was thoughtful.

The miracles still continue.

[During the Sui and Tang Dynasties, the steel filling method further expanded its scale.It laid the foundation for the popularization of a large number of high-quality armor weapons in the Tang Dynasty. At the same time, in the production of iron tools, the Tang Dynasty had begun to use forging on a large scale, which promoted the diversification of iron tools and the complexity of their structures. It not only improved the quality of iron armor The aesthetics, quality, and practicality of it are also enhanced. 】

[The standard armor of the Tang Dynasty is very similar to the armor of the Southern and Northern Dynasties, but the armor pieces of the Tang Dynasty are larger and layered]

[The coverage range far exceeds that of the armor of the Northern and Southern Dynasties. The armor coverage range can be from the neck to the ankles, occupying almost [-]% of the body. This also makes the protective capabilities of the Tang Dynasty cavalry almost the most powerful in all dynasties. 】

[At the same time, the weapons of the Tang Dynasty cavalry also benefited from the development of forged iron technology, making them sharper, lighter, and more lethal! 】
-
Han Dynasty, Jian'an period.

Cao Cao looked at the different sets of armors of the Tang army. He couldn't see the end of the high-quality weapons, and his eyes almost glowed red!
He is so short of weapons!

And this armor looks extremely extraordinary!

Now his horse only wears some leather armor, and the cavalry only has some iron armor, and it doesn't cover the whole body!
Inadequate equipment resulted in dozens of war horses being damaged in every battle!

It makes him heartbroken every time!

If he could have heavy cavalry like the Tang Dynasty, there would be no place in the world that he couldn't conquer!

[The reason why the cavalry under Li Shimin can play such a great role is not only because of their well-equipped and outstanding generals, but also because of their extremely excellent combat methods. 】

[The cavalry of the Tang Army did not just rush forward mindlessly, on the contrary, under the leadership of Li Shimin]

[Although the cavalry of the Tang Dynasty was heavily armored, it not only did not charge blindly, but also paid attention to flexibility. Most of them cooperated with the infantry. The infantry attracted the main force, and the cavalry entered from the side and broke up the enemy's formation, thus causing the opponent to collapse and win in one fell swoop. . 】

[The most valuable thing is that under the leadership of Li Shimin, Tang Jun has always maintained a humble heart and knows how to reflect and look for his own problems at all times. 】

[After many battles, the Tang army became more and more aware of how critical the mobility of cavalry was. Therefore, most of the time their horses were not equipped, but the men wore armor and the horses were not changed, forming a simplified version of heavy cavalry. 】

[It not only ensures the flexibility of the cavalry, but also ensures its strong ability to charge into battle, and this style was passed down by the Tang Dynasty and even to later generations. 】

[Therefore, in the Tang Dynasty during Li Shimin's time, many people who joined the army were proud to be cavalry, and the cavalry was honored to join Li Shimin's establishment. Once they entered the army, all the neighbors would send congratulations! 】
