Chapter 434

After the beating is formed, it begins to immerse in the liquid for annealing, and then throws the beaten iron sheet into the bamboo basket next to it.

"The quality of the iron ore in my Song Dynasty is not very good, so we can only use this kind of hot forging method. If it is cold forging..." The official seemed to think that no matter how much he said, it would be better to let the people see it.

The craftsman asked the craftsman to pick up the piece of iron that had just been annealed and then began to forge. Although the craftsman looked puzzled, he still followed the official's order to start cold forging.

However, after hitting twenty or thirty hammers, the originally complete iron piece had already cracked.

"..." Zhao Xu, Zhao Ji, and Wang Yang were all dumbfounded at the shattered 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 inferior." Wang Yang stretched out his hand, picked up a piece of iron material and looked in his hand for a long time, and finally came to such a conclusion. Seeing that the traces of yellow water flowing across the ground were 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 make the metal brittle. The scene in front of us seems to just confirm it.

In addition, Wang Yang seems to remember that although there are many iron ore in Huaxia, there are very few high-quality low-pyrodite ore. In addition, because Dasong used wood carbon to smel metals, he began to use coal carbon to smelter metals on a large scale.

You should know that the sulfur content in coal is originally not small, so if sulfur is added to sulfur, it will be a ghost to make good steel and good iron.

"Sir, you..." Zhao Ji was stunned when he saw Wang Yang picking up a piece of broken iron from the iron felt, and he didn't care at first.

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

However, as soon as he said that, Zhao Xu was pulled by him, and he specially put the index finger of the other hand in front of his lips and pointed at Wang Yang again.

That means that the eleven-lantern should not disturb Wang Yang in contemplation. The official and the blacksmith also looked at the top scholar who was in a daze in a daze. He didn't quite understand why Wang Yang was so rudely staring here. His Highness went to call him, but His Majesty didn't allow him, and even signaled everyone to be quiet. What's the point of making a fuss?

Only Zhao Xu himself knew that when he saw Wang Yang muttering to himself with the broken piece of 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, which can make the quality of the Song Dynasty's iron armor as hard and firm as those Western Xia wart armors.

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

"...So that's it, I understand, hahaha..." Wang Yang finally figured out why the iron production in the middle of the Song Dynasty recorded in the history of the Song Dynasty had increased rapidly, but the quality of the armor was not as good as the backward areas of Xixia and Northern Liao.

"Sir, what do you understand?" Zhao Ji could not bear it. At this time, he saw Wang Yang suddenly laughing wildly and asked subconsciously.

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

"Is there any such statement?" The official in charge of armor making could not help but be stunned and asked subconsciously.

"Because our Song Dynasty uses coal to smeltek now, while the Northern Liao and Western Xia use wood and carbon, which is a clear proof." Wang Yang said for granted.

"And it has a lot to do with the quality of our iron ore. Our iron ore should have a high sulfur content, and it has not been processed before use, right?"

"Order dressing, of course I will choose. Experienced old craftsmen will choose ore blocks and choose ore with higher iron content..." The official quickly stated.

"I'm not talking about this kind of ore dressing. I'm talking about whether your ore is first ground into ore powder and then used magnets to pick it?" Wang Yang asked.

"..." The official looked at Wang Yang with a confused look on his face. "Ball milling, magnet selection? The top scholar, what are the steps?"

"There is also the coal you use to smelter ore must be bituminous coal, right?" Wang Yang said with a confident look on his face.

"That's natural, because the firepower of bituminous coal will be greater than that of anthracite." This time the answer was not the official, but the craftsman who just smashed the iron sheet.

"Do you know that the sulfur content in bituminous coal is extremely high, and sulfur is something that causes iron tools to rust easily. If the content is too high, it will not only rust easily, but also reduce its quality, reduce its ductility, and become very brittle and brittle."

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

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

"Then, can there be a way to eliminate it and make my Song Dynasty armor strong, like the Western Xia wart armor?" Zhao Xu looked at Wang Yang and couldn't help asking.

"Of course, it can even make my Song Dynasty armor lighter and more protective power stronger." Wang Yang sniffed. There was no such thing as this world that could not be difficult for him. He had found the biggest hidden danger of the Song Dynasty's steel industry, naturally...

Well... Do you want to let the Song Dynasty go past the Heavy Armor era hundreds of years in advance and enter the Firearm Age? At this moment, Wang Yang seemed to feel the pressure of the heavy padded history on his body.

Are you going to do it? But now it seems that there is still a lot of tools and preparations. It seems unlikely to use gunpowder weapons directly. In other words, the Emperor of Song Dynasty has not yet stood in the position of the highest ruler, so he just told the other party rashly, let's make firearms.

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

No, only fools can use gunpowder weapons that explode at any time. Maybe they will become sinners in history because of those unqualified gunpowder weapons.

"Zhuangyuan Gong, aren't you kidding?" The official from the armor workshop couldn't help but complain when he saw Wang Yang's attitude of being almost awesome.

"Please rest assured, sir, Wang always speaks with spit and nails. If he can do it, then Wang will definitely be able to do it."

However, although Zhao Xu was very excited but hesitant, Wang Yang smiled at Zhao Ji. "Your Highness, do you still remember that when Wang Yang bought shares in the Wu family smelting workshop today, Wang took a coking technique and handed it to the boss Wu."
