Lin Zifan smiled confidently and said, "The most conservative estimate, the worst part, the iron content is ...... More than seventy percent!"

"The best ones may even exceed seventy percent, reach eighty percent or even ninety percent!"

"Maybe a lot of adults don't know what this number represents. Lin Zifan looked around at everyone, then looked at the empress affectionately, and said quietly: "More than seventy percent of the iron ore doesn't even need to be further selected, you can directly start making iron, and even ...... Steelmaking!"

"Hiss!!"

From the empress to the civil and military officials, they all gasped.

"Lin Shangshu, this is ...... Are you sure?" the national teacher looked solemn and immediately asked.

"Nature can be determined!" Lin Zifan nodded confidently, which shocked the civil and military officials, and at the same time, almost everyone was overjoyed.

Iron smelting can be started directly, and there is no need for even selection and preliminary smelting...... Is it really possible?

You must know that before this, nearly half of the iron ore purchased by the Tang Dynasty from the Qin State had to be discarded, because those iron ores were no different from stones, and the iron content was pitiful.

The remaining part also has to go through preliminary smelting, and after removing most of the impurities, the second smelting is carried out to remove the remaining impurities and start the actual iron smelting.

The third step is to make smelted iron ingots and the like into weapons, armor and other necessary things.

Among them, it is not only labor-intensive, but also financial, and thankless.

If Anshan Iron Mine can reach the standard and level that Lin Zifan said, how amazing is it?

Everyone gasped at the thought of this......

The empress's eyes were gloomy, as if she had seen the future, and she asked, "What Lin Shangshu just said is ...... Steelmaking?"

"Steel, what?"

"Your Majesty, steel is a kind of iron that is harder, more stable, and more valuable than iron!"

Lin Zifan opened his mouth and began to popularize the knowledge of steel for the empress and civil and military officials.

The difference between steel and iron, in fact, will be learned in high school or even junior high school, theoretically speaking, steel is the evolution of iron, and the refining methods are relatively close, but the carbon content and impurities of steel are much lower than iron!

To put it simply, pig iron is iron that has just been extracted from iron ore, in which there are more carbon elements and many impurities, so it is called pig iron.

And if pig iron is mixed and smelted with some other kinds of metals, if the means are right, steel alloys can be smelted.

Most of the common steels on the market are alloys!

But Datang obviously doesn't have so many metals, and it can't reach that technology, and even Lin Zifan himself can't figure out how the blast furnace of steelmaking works.

It is impossible to explain carbon to the empress or something, and it is impossible to do so, so in this way, you can only give it up.

Therefore, what Lin Zifan wants to talk about is another method...... Expertise is the result of long and hard practice!

Steel alloys mixed with other metals have, to many extent, some advantages over ordinary steel.

But the steel that has been refined into steel is also not weak!

The principle of 100 smelting into steel is to smelt pig iron with high carbon content and magazine magazine at high temperature repeatedly, so that carbon and oxygen react at high temperature to become carbon dioxide, and continuously reduce the carbon element in pig iron.

After many smelting, pig iron becomes steel!

Within a certain range, the more smelted times, the higher the purity of the steel!

Of course, Lin Zifan didn't talk about carbon and carbon dioxide or anything, he just explained the general meaning of refining into steel, and with the wisdom of the empress and civil and military officials, it was not difficult to understand......

"Steel?"

The empress nodded slowly: "It turns out that after iron has been smelted and forged many times, is it called steel?" I know that there are many weapon masters, when forging weapons, they will overturn the high-temperature forging, so that the quality of the weapons is higher than before. ”

"It turns out that they forged iron into steel?"

"That's it!" Lin Zifan nodded slowly: "Ordinary iron, it is indeed possible to use this means to make it more powerful, until it reaches the critical point of the material itself." ”

"Perhaps, you still have some doubts. ”

"This time, the minister brought back some iron ore from Anshan, although it is not much, but it is enough for you to demonstrate, I hope Your Majesty will allow it!"

"Accurate!"

The empress almost didn't think about it, and waved her hand in agreement.

Datang has been short of iron for many years, and even from the beginning of the founding of the People's Republic of China to the present, there is no day when there is no shortage of iron.

At this moment, Lin Zifan finally found iron ore, and he could even make steel, which was a more powerful existence than iron, how could the empress not be anxious?

After the empress agreed, Lin Zifan immediately asked the daughters of the department to take out some iron ore. After seeing these iron mines, the empress and the civil and military officials were amazed.

Even, the empress directly dodged and appeared beside Li Lin Zifan, took a piece of iron ore in her hand, and looked at it carefully.

"This ...... It's almost like a lump of iron?"

The empress tilted her head, and her surprised look made her look even more moving: "No wonder it can be smelted directly, compared to the iron ore purchased from the Qin State before, what is it?"

"It's just broken stones!"

General Huo Da turned out to be topical, and scolded: "Damn Qin State, it is really hateful to sell us defective products at such a high price!"

"If there is a chance in the future, I will definitely hit their capital and let them return all the money!"

This time, no one objected to General Huo's words, and even the civilian officials nodded their heads in agreement......

As the saying goes, if you are not afraid of not knowing the goods, you are afraid of comparing the goods!

At the beginning, there was no iron mine in Datang at all, from the empress and the civil and military officials, down to the people of Liming, everyone had never seen iron ore, and naturally they couldn't tell the difference between good and bad.

Even everyone naively thought that the iron ore was sold to the Tang Dynasty by the Qin State, so they didn't think there was anything wrong.

But now, looking at the iron ore that Lin Zifan brought back, the contrast is bright...... The gap couldn't be more obvious!

As long as you are not blind, you can clearly see the gap, okay?

To put it simply, the iron ore imported from the Qin State is in your hand, and you have to find iron from the stones, but the iron ore in Anshan has just been turned over, and iron is everywhere, and it is more difficult to find stones!

This discovery, how can the civil and military officials not be annoyed?

Over the years, Datang has spent so much silver, and all the products he bought are defective products......

Until now, I didn't know that I and even the entire court were being led by Qin Guo to play with my nose, and I didn't know it!
