Chapter 434

When it is beaten into shape, it begins to immerse itself in the liquid for annealing, and then throws the beaten piece of iron into a bamboo basket next to it.

"The quality of my iron ore in the Great Song Dynasty is not very good, so I can only use this hot forging method, if it is cold forging...... the official seems to think that no matter how much he says, it is better to let this group of people see it as believe.

The craftsman was asked to pick up the piece of iron that had just been annealed, and then began to forge it, and although the craftsman looked inexplicable, he still followed the official's orders and began to forge it cold.

It's just that after twenty or thirty hammers, the piece of iron that was originally intact has cracked.

"......" Zhao Xu, Zhao Ji, and Wang Yang all looked at the shattered piece of armor in amazement, what the hell is this?

"Your Majesty, this is the reason why my Great Song Dynasty's iron armor cannot be cold-forged......"

"The iron is too inferior." Wang Yang stretched out his hand, picked up a piece of iron material and looked at it in his hand for a long time, and finally came to such a conclusion, and saw that on the ground, there were traces left by the yellow water flowing sideways, Wang Yang suddenly thought of a question.

If the sulfur content in the iron is too high, it will indeed reduce the tensile strength of the metal and make the metal brittle. And the scene in front of me seems to be just confirmed.

In addition, Wang Yang seems to remember that although there are many iron ores in China, there are very few high-quality low-sulfur iron ores. In addition, the Great Song Dynasty began to use coal charcoal to smelt iron on a large scale because it swept away the past practice of using wood charcoal to smelt metals.

You must know that among the coal, the sulfur content is not small, so sulfur and sulfur can be smelted into good steel and iron.

"Sir, ......" Zhao Ji began to be stunned when he saw Wang Yang pick up a piece of broken iron from the iron felt, and he didn't think about it at first.

But now, after more than ten breaths, he still looked at the piece of iron in his hand with straight eyes, and he didn't know what he was muttering in his mouth, so he couldn't help but ask in a low voice.

But as soon as the words came out, he was pulled by Zhao Xu beside him, and he specially put the index finger of his other hand in front of his lips and pointed at Wang Yang.

That means that Eleven Lang should not disturb Wang Yang who was contemplative, the official and the blacksmith also looked at this champion who was in a daze with some confusion, and did not understand why Wang Yang was so rude here, His Royal Highness the Prince called, His Majesty did not allow it, and even signaled everyone to be quiet, what kind of trouble is this?

Only Zhao Xu himself knew, and when he saw Wang Yang muttering to himself with that piece of broken iron, he couldn't help but think of Wang Yang's countless jaw-dropping achievements in the past.

Perhaps, he really has a way to solve it, and he can make the quality of the iron armor of the Great Song Dynasty as hard and firm as those of the Western Xia Poor Armor.

Therefore, Zhao Xu stopped Zhao Ji's behavior that might interfere with Wang Yang's thinking.

“…… I see, I understand, hahahaha...... "Wang Yang finally figured out why the iron production began to increase by leaps and bounds in the middle of the Great Song Dynasty recorded in the history of the Great Song Dynasty, but the quality of armor was not comparable to those backward areas of Western Xia and Northern Liao.

"What do you understand, sir?" Zhao Ji couldn't bear it anymore, and at this time, when he saw Wang Yang suddenly laughing wildly, he couldn't help but ask subconsciously.

"I know why the quality of our steel products in the Great Song Dynasty is not as good as that of the Western Xia and Northern Liao barbarians. The problem is our iron ore and fuel. ”

"Is there anything else like that?" The official in charge of armor production couldn't help but be stunned, and subconsciously asked.

"Because our Great Song Dynasty now uses coal for iron smelting, while Northern Liao and Western Xia use wood charcoal, which is proof of this." Wang Yang's face was as natural as a matter of course.

"Moreover, it has a lot to do with the quality of our iron ore, our iron ore should have a high sulfur content, and before use, there is no beneficiation, right?"

"Beneficiation, of course, will be chosen, there will be experienced old craftsmen to select ore blocks, choose ores with higher iron content......" the official hurriedly affirmed.

"I'm not talking about this kind of beneficiation, I'm talking about whether your ore is first ball-milled into ore powder and then mined with magnets?" Wang Yang asked.

"......," the official looked at Wang Yang with a confused expression. Ball milling, magnet mining? Champion, what are these steps? ”

"In addition, the coal you use to smelt ore must be bituminous coal, right?" Wang Yang said with a determined face.

"That's natural, because bituminous coal has more firepower than anthracite." This time it was not the official who answered, but the craftsman who had just smashed the piece of iron.

"Do you know that bituminous coal has a very high sulfur content, and sulfur is something that causes iron to rust, if the content is too high, it will not only make steel rusty, but also reduce its quality, reduce ductility, and become very brittle and brittle."

"Sulfur...... Wang Qingjia, what is this sulfur? ”

"It's the sulfur used in our traditional Chinese medicine." Wang Yang patted his forehead and thought about it for a long time, and finally came up with a simple and common solid sulfur.

"Then, is there a way to eliminate it, so that my Great Song armor is as strong as the armor of the Western Xia?" Zhao Xu looked at Wang Yang and couldn't help but ask.

"Of course you can, and it can even make my Great Song armor lighter. And the protection is even stronger. Wang Yang sniffed, there is really nothing in this world that can be difficult to hold on to himself, and he has found the biggest hidden danger in the Great Song Iron and Steel Industry, naturally......

Not...... Do you want to let the Great Song Dynasty directly cross the era of heavy armor and enter the era of firearms directly hundreds of years in advance? At this moment, Wang Yang seemed to feel the pressure of the heavy cushion of history on his body.

Do you want to do it? However, it seems that there is still a lack of a lot of tools and preparations, and it seems impossible to directly use gunpowder weapons, or rather, the current Emperor of the Great Song Dynasty has not yet stood in the position of the supreme ruler, so he recklessly told the other party, let's get firearms.

However, the problem is that gunpowder weapons cannot be effective in three or five days, and it is better to focus on improving the quality of steel first, as long as enough qualified steel can be produced, and then it is more feasible to consider gunpowder weapons at that time.

No, only fools use gunpowder weapons that explode at every turn, and maybe they will become sinners in history because of those unqualified gunpowder weapons.

"Champion Gong, you can't be joking, are you?" The official of the armor workshop couldn't help but complain when he saw Wang Yang's posture of being about to reach the sky.

"This adult, please rest assured, Wang has always spoken with a mouthful of spit and a nail, and if he can do it, then Wang will definitely be able to do it."

However, seeing that although Zhao Xu was very excited, he was a little hesitant, Wang Yang smiled at Zhao Ji. "Your Highness, do you still remember that when Wang Yang became a shareholder in the Wu smelting workshop today, Wang took a copy of the coke refining technique and handed it to that Boss Wu."

"Remember, what's wrong?"
