Chapter 435 The Big Reason Is Smelting Fuel (Part [-])
Chapter 434

After beating into a shape, it began to be immersed in the liquid for annealing, and then threw the beaten iron piece into a bamboo basket beside it.

"The quality of the iron ore in my Song Dynasty is not very good, so at most I can only use this method of hot forging, if it is cold forging..." The official seemed to feel that no matter how much he said, it would be better for the group to see it. For reality.

Ask the craftsman to pick up the piece of iron that has just been annealed, and then start forging. Although the craftsman looks puzzled, he still follows the official's order and starts cold forging.

However, after [-] or [-] strikes with the hammer, the originally complete piece of iron had cracked.

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

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

"The iron material is too low-quality." Wang Yang stretched out his hand, picked up a piece of iron material and looked at it for a long time, and finally came to such a conclusion, and saw the yellow water flowing across the ground everywhere. Wang Yang suddenly thought of a question.

If the sulfur content in the iron material is too high, it will indeed reduce the tensile strength of the metal, and it will also make the metal brittle.And the scene in front of him seems to confirm it.

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

You know, the sulfur content in coal is not small, so adding sulfur to sulfur, you can make good steel and good iron.

"Sir, you..." Zhao Ji saw that Wang Yang picked up a piece of broken iron from the iron felt, and then he started to be dazed, and he didn't take it seriously at first.

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

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

That means to tell Eleven Lang not to disturb Wang Yang, who is in deep thought. The official and the blacksmith also looked at the number one scholar who was in a daze, not quite understanding why Wang Yang was so impolitely dazed here. , His Majesty went to call the Prince, but His Majesty did not allow it, and even signaled that everyone should be quiet. What kind of trouble is this?
Only Zhao Xu himself knew clearly that when he saw Wang Yang holding the broken piece of iron and mumbling to himself, 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 make the quality of Song Dynasty's iron armor as hard and solid as those of Xixia armor.

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

"...So that's it, I understand, hahahaha..." Wang Yang finally figured out why the iron output recorded in the history of the Song Dynasty began to increase by leaps and bounds in the middle of the Song Dynasty, but the quality of armor was not as good as that of Xixia and Xixia. The reasons for those backward areas in Northern Liao.

"Sir, what do you understand?" Zhao Ji couldn't bear it anymore. 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 current steel products in the Song Dynasty is not as good as that of Xixia and Northern Liao barbarians. The problem lies in our iron ore and fuel."

"Is there still such a saying?" The official in charge of armor production couldn't help but asked subconsciously.

"Because our Song Dynasty now uses coal to make iron, while Northern Liao and Xixia use charcoal. This is proof." Wang Yang said matter-of-factly.

"Moreover, it also has a lot to do with the quality of our iron ore. Our iron ore should contain high sulfur, and it has not been beneficiated before use, right?"

"Ore beneficiation, of course, will be selected. There will be experienced old craftsmen who will select ore blocks, and choose ore with higher iron content..." The official quickly declared.

"I'm not talking about this kind of ore dressing. What I'm talking about is whether your ore has been ball-milled into ore powder before being mined with a magnet?" Wang Yang asked.

"..." The official looked at Wang Yang in confusion. "Ball milling, magnet mining? Zhuangyuan Gong, what are these steps?"

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

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

"Then do you know that the sulfur content in bituminous coal is extremely high, and sulfur is the thing that causes iron to rust easily. If the content is too high, it will not only make the steel easy to rust, but also reduce the Its quality reduces ductility and makes it very brittle."

"Sulphur... Wang Qing's family, what is this sulfur?"

"It's the sulfur used in our traditional Chinese medicine." After patting his forehead, Wang Yang thought for a long time, and finally thought of a simple and common solid sulfur.

"Then, is there a way to eliminate it and make my Song Dynasty's armor as strong as the Xixia armor?" Zhao Xu looked at Wang Yang and couldn't help but ask.

"Of course, it can even make my Da Song's armor lighter. And the protection is stronger." Wang Yang sniffed. There is really nothing in this world that can stop him, and he has already found it. The biggest hidden danger of Dasong Iron and Steel Industry is naturally...

Hmm... Do you want the Song Dynasty to skip the heavy armor era and directly enter the firearms era hundreds of years in advance?At this moment, Wang Yang seemed to feel the pressure of history weighing heavily on him.

Do you want to do it?However, it seems that there is still a lack of a lot of tools and preparations. It seems impossible to use gunpowder weapons directly. Firearms.

But the problem is that gunpowder weapons will not be effective in three to five days. It is better to focus on improving the quality of steel first. As long as enough qualified steel can be produced, it is more feasible to consider gunpowder weapons at that time.

No, gunpowder weapons that explode at every turn are only used by fools. Maybe I will become a sinner in history because of those unqualified gunpowder weapons.

"Master Zhuangyuan, are you kidding me?" The official of the armor workshop couldn't help complaining when he saw Wang Yang's almost arrogant attitude.

"My lord, please don't worry, Mr. Wang has always been spitting and nailing his words. If he can do it, then Mr. Wang will definitely be able to do it."

However, seeing that although Zhao Xu was very excited, but hesitant, Wang Yang smiled at Zhao Ji. "Your Highness, do you still remember that when Wang Yang became a shareholder in Wu's smelting workshop today, Wang took a coking technique and gave it to Boss Wu?"

"Remember, what happened?"
