"Outside, this is that kind of Xia Guojian." Zhu Qing presented the sword.

Zhu Huan took out the open sword and tried its sharpness, and asked strangely: "A small village, how can you forge this kind of sword?" ”

"Outside, it seems that they used the hundred-fold method, and they also used charcoal to bake for a long time, so I can't ask about the specific process."

The most famous tools for forging in ancient times are 100 steels and 100 stacks of steel.

Hundred steel is to put iron on charcoal or charcoal to burn red, then forge and quench, and then burn red forging, repeat a hundred times. The hundred-fold steel is more complicated, not only has to be burned red, but also a stacking process is added.

The actual process is very complicated, but the principle is very simple, that is, carbide steel.

It is rumored that the Tang Dynasty Mo knife used a hundred stacks of steel technology, because there is a stacking process, the carbonization will be more uniform, if it is really done a hundred times of stacking, it is a terrible stack, two to the hundred power.

But Wang Ju doesn't think that the Tang Dynasty Mo knife really does a hundred stacks, not to mention the terrible artificial, let's just talk about the cost, although the iron and carbon have a chemical reaction at high temperature, but there is also an oxidation reaction in the high temperature process, so forging iron will be reduced once, if it is done a hundred times of stacking, a hundred catties may not have a pound of iron left. Iron in ancient times was very expensive, and an ordinary pound of pig iron on the market in the Song Dynasty was equivalent to about 30 Wen.

Therefore, in the Ming Dynasty, there was steel frying and steel filling, which was actually a simple carbonization process.

Wang Ju did not use these two methods, the cost is too high, and the process is also complicated, which is not something that Wangjiazhai can support.

He chose the steelmaking technology of the early industrialization of Europe, first dismantling the knife into pieces and putting them together with the charcoal to completely seal and heat them, reducing oxidation and improving the carbon soaking process.

It's a rough process, but it's simple.

After heating for a few days, these irons are taken out and repeatedly stacked, and the effect of 100 steelmaking is to remove carbon and impurities, because the number of forging is large, the grain can be refined and the composition can be uniform.

But I won't really go to a hundred stacks, and I will stack them a dozen times. There are blacksmiths in the village, Yuan Heizi, but Yuan Heizi's craftsmanship is still very difficult.

Anyway, it's an experimental object, including his simple carbon steel, which also needs to be improved.

So there was the product in front of you.

The effect was not bad, Zhu Huan continued to stare at the sword and asked, "Where did he hear about this technique?" ”

"Outside, I asked, he said that he was in the security army city, and overheard a Western Xia businessman revealed, probably thought he was young, but he didn't expect to be remembered by him. But he didn't pay attention to it at the time, one was small, and the other was poor experience, when Hei Aoling dealt with the follow-up in the first battle, he remembered it and tried it. ”

"All the swords here?"

"No, I only brought ten swords, and I should be able to shoot ten swords."

"That is, forty knives can become twenty swords?"

"Not bad."

"Why is there so little loss?" Zhu Huan couldn't help pacing around, and suddenly smiled again: "What a suspicious teenager." ”

Striking a sword is only a part, but also the hilt, scabbard, and decorative sword bag or sword case are also made. This involves leather technology, inlay technology, wood technology, lacquer technology, and smelting process, which is far from being able to be done by Wangjiazhai. And if the sword is made, there must be a sales channel, even if it is a real Xia Guo sword, can it be sold at a high price in the hands of the people of Wangjiazhai?

However, Wangjiazhai is not completely at a disadvantage, in the final analysis, he must have a sword in his hand.

In fact, Zhu Huan's appearance was good, and all the money for those horses was given to Wangjiazhai as a pension.

But that's different, it's a one-off, it's a long-term thing, it's a business, and Wang Ju can't figure out Zhu Huan's heart. The Zhu family definitely wants to earn a little, but the proportion of earnings is the key.

So he only handed over ten, if the Zhu family was too dark-hearted, Wang Ju would find someone else, it might be troublesome, but be prepared.

Zhu Qing was happy.

"Forget it, find someone to process these ten swords, see how much money they sell, and make half of the profits."

"Extraneous and wise."

The Zhu family is inferior to other big families in Yanzhou, but it only rose when Zhu Huan was father and son, and the trick is that the appearance is not ugly, of course, if the Zhu family is provoked, the Zhu family will also be decisive. This is the true way to survive on the border.

Zhu Qing turned his head to look at Zhu Huan's second son Zhu Jun again: "What's wrong with Erlangjun?" ”

Where Zhu Jun was punished for kneeling, it has been a long time.

"I was so angry with this little beast that he met a beggar on the road yesterday and gave him a few taels of gold ingots."

A trace of worry also flashed in Zhu Qing's eyes, Zhu Huan has a total of four children, the latter two children were born to concubines, still young, Zhu Huan's wife gave birth to two sons, the eldest son Zhu Qi loves male style, and has been married for several years without children, and some people even say that Zhu Qi's wife is still a virgin. The second son, Zhu Jun, is another nerd.

"It's not more than three generations rich, can't the Zhu family survive three generations?" Zhu Qing thought secretly in his heart.

He had an idea.

"Steward Zhu, what do you want to say?"

"It's better to let Erlangjun go to Wangjiazhai."

"It's not proper," Zhu Huan said, that there is a handover between the owner and the mule?

"With the sword, will that stockade still be a mule in the future? Erlangjun is not a stupid person, but he lacks some training, and that young man is eccentric and clever, and he is decisive, which is exactly what Erlangjun lacks. ”

Zhu Huan was a little moved by this.

…………

Motokuroko raised the hammer and forged the sword on the forging stone vigorously, the sound was as beautiful as a powerful symphony, but Motokuroko was sweating like rain.

"Put it in the furnace." Wang Ju said.

Yuan Heizi put it back into the furnace, and when it burned red, Wang Ju said again: "Take it out, no, add a little hot charcoal." ”

This time, Yuan Heizi didn't have to do it himself, a few of his apprentices did it for him.

"Why?"

"I don't know, but that's how the mountain is forged," Wang Ju replied simply. This is the normalizing quenching process. A complicated process, even if you want a good sword, you have to test oil quenching and salt water quenching...... Even this simple forging requires quenching technology, but unfortunately no one pays attention to it in this era.

Wang Ju's quenching process is still extremely dry, but the principle makes Wang Ju how to answer, and everyone can't understand it.

"I'm not a material expert, so I can only debug it slowly," Wang Juxin thought.

After a while, Wang Ju said, "It's almost." ”

Yuan Heizi's apprentice, Wang Quan's second son, Wang Qiang, immediately took out the sword and threw it into the furnace, then burned it red, and then put it into the stream water to quench it.

looked at Jian Yuan Heizi and said, "Big Niu, how much will it be worth?" ”

"Just a few dollars?" Wang Ju laughed dumbly. There are three kinds of weapons in Western Xia that can be taken out, cold-forged armor, Western Xia bow, Xia State sword, a good Xia State sword is worth thousands of gold, one thousand taels of gold, and twenty thousand yuan. Of course, this value of thousands of gold is an imaginary number, but the best Xia Guojian is often worth thousands of dollars, and even the slightly worse ones are worth hundreds of dollars.

Wang Ju doesn't expect to be able to sell for a few hundred yuan, but he won't be able to sell it for just a few yuan.

A villager came up to him and said, "The steward of the proprietor is here." ”

"Say Cao Cao Cao will arrive, go, see how much money his family gives."

When he came to Wang's house, after a little cold noise, Zhu Qing pointed to the sword box and said, "It is the real Xia Guo Sword." ”

Z: "Can you give me a look." ”

"I asked me to bring it for you to see and learn from, but it doesn't hurt to see it."

Zhu Qing said, pulling out the Xia Guo sword from the scabbard.

"Little brother, look at its craftsmanship, as well as sharpness and toughness......"

The scabbard has a gorgeous northwestern-style ornament, and the blade of the sword is green and cold, like a proud prince.

"Good sword," Wang Ju exclaimed, stroking the sword.

The Zhu family brought the Xia Guo sword, not only for Wang Ju to watch and learn from, but also to show that the Zhu family is not black-hearted, and there is still a big gap between the sword you cast and others, and it can only be worth so much money.

After reading it, Zhu Qing said the right thing: "The staff plans to give you a sword for twenty times." ”

"Twenty?" Yuan Heizi couldn't help but look at his hands, he could actually shoot a weapon of twenty times?

Others are also happy, a sword is twenty times, and twenty swords will be four hundred yuan, which is the income that the whole village can't get as a mule for a year!

Wang Ju's face was very calm, mainly because the craftsmanship and quality could not keep up, if he could cast a real high-grade Xia Guo sword, it would not be much for two hundred yuan.

And it does not include the cost of other materials such as iron and carbon, if it were not for those knives, give twenty yuan, maybe the village can only actually end up with ten yuan. However, for the poor village, it is also a considerable amount. And with the improvement of the process, the profit will gradually increase. Therefore, Wang Ju did not speak.

"The staff said that the profits are divided in half, little brother, what do you think?"

Wang Ju nodded, so the Zhu family is very sincere, after all, there is also a lot of work over there.

"But if that's the case, I hope Dong Weng will provide you with fine iron, as well as charcoal, and some other materials, and I'll write you a list later."

In the Song Dynasty, coal began to be mined and used on a large scale, and there were also two coal pits in Yanzhou, but the quality was not very good. As for iron, it is a strictly guarded material, and it is officially produced, and Wangjiazhai has no channels to obtain a large amount of pig iron or wrought iron, not to mention that it must be good iron.

"Okay."

"In addition, I will ask Dong Weng to provide two highly skilled blacksmiths to come and support."

Zhu Qinghu looked at Wang Ju suspiciously.

Wang Ju is also helpless, Yuan Heizi's craftsmanship is also good, but if you want to cast a high-grade Xia Guo sword, you can't keep up, not to mention the understanding of the complex quenching process, even if you stack and forge Yuan Heizi, you can't do excellence. And in order to improve the degree, Yuan Heizi brought several apprentices, which is a good thing, but he must be taught by hand, and Yuan Heizi is too busy alone.

As for whether the blacksmith of the Zhu family will learn it, it is possible that the core technology is in that sealing kiln.

Zhu Qing couldn't figure out the intention, but he still nodded in agreement.

"This sword will be left for a few months, and then it will be returned to Dong Weng, can we return it to Dong Weng?"

"No problem."

"That's the agreement." The two high-fived as an oath.

"Little brother, you come with me." Zhu Qing took Wang Ju outside, and there was a handsome young man standing outside, sixteen or seventeen years old: "He is Erlangjun outside the staff." ”

"I've seen Zhu Erlang."

"I've seen Xiaolang."

"What you mean is that you want Erlang-kun to stay at your house for a while."

"He's staying at my house?" Wang Ju pointed to Zhu Jun's gorgeous clothes and couldn't help laughing.

ps: Cold forging armor, generally forging is hot forging, but this cold forging process is to wait for the iron to cool and then forge, so that the nail piece is stronger, of course, it is more labor-intensive, and because it is difficult to forge after cold, it can only be used for thin armor, not for thick swords.

The bow and crossbow shoot farther and more accurately, not necessarily in the rally, as well as the material and scientific design, such as the bow and arrow rally in the later Olympic Games only need 30 to 50 pounds, in the Song Dynasty can not pull a bow with one stone and two stones, are not considered qualified crossbowmen. However, the range and accuracy of the bow of the Song Dynasty may not be as good as the "light bow" of later generations. There are good design problems with the Xixia bow and crossbow, and the yak horn of Ganzhou is also used, where did the Song Dynasty get the Ganzhou yak horn, which is a strategic material of the Western Xia, and even if it is obtained, it is very rare. Therefore, often a Xixia bow will be worth hundreds of dollars.

and Xia Guojian, which may have used a hundred stacks of forging process, but there may be some alloy technology.

These three processes are complex, the yield is low, the cost is high, even if the Western Xia is not much, the Song Dynasty has tried to cottage many times, but has not succeeded, so this sentence is left, "Khitan saddle, Xia Guojian, Goryeo secret color, are the first in the world, although they are effective, they can't be reached." ”

Steel, steel, steel
