Xu Huai looked at a small bundle of wire iron, which was as thick as a grain of rice in his hand, and some fragments of memory emerged. He thought that this might be more appropriate to call it iron wire or wire. He looked at the official responsible for escorting materials and asked, "Can you know how the wire iron is forged?"

After the escort officer sent by Anzhou to Huangyangzhai for delivery, he returned to the original route. After taking a section of land from Huangyangzhai, the goods arrived at Qingyiling and then loaded the ship to Qingyishui. When Rushui went to Zhaoling, the officials were responsible for the Chushan camp. How could they know the technical details of the casting of wire and iron?

Besides, these wires are physical taxes collected by the Anzhou Prefecture Office from the local area. How could the escort officer, who is mainly military officials, know the method of smelting and forging? Even if he is pulled over, it will be difficult to answer Xu Huai's questions.

"If you want to know the method of forging, you can ask Zhuang Yong." Chen Zixiao saw that the escort officer was confused when he was standing in front of Xu Huai, and he only knew a little roughly and could not explain the specific details. He suggested that Zhuang Yong be asked.

The construction of Zhaoling New City is much more complicated than that of ordinary hamlets in the world. Yu Chengzhen and Zhuang Yong, the son of Zhuang Shouxin, were the construction officers and deputy supervisors stayed in Zhaoling for a year and had not left at that time.

Yu Chengzhen is better at creating, while Zhuang Yong is better at forging.

Before waiting for Zhuang Yong to come, Wang Xian, Han Gui, Jiang Xie, Fan Zongqi, Wu Chihai and others also curiously took a small piece of wire and looked at it.

Xu Huai smiled and said, "This wire, iron, is more vivid, and Zixiao said that it is a bit difficult to find out the detailed forging method of yours, but you can think about it. If this wire and iron are handed to you, how should it be used?"

Fan Zongqi said: "The craftsman pulls gold, silver and copper wires, which are mostly used for decoration of utensils. This off-white iron wire is like old silver, and should be able to replace old silver wires. However, the price of the judging is not comparable to ours. However, it is a lot of advantages to replace ropes, but it is a bit too extravagant than copper wires..."

The price is actually more rare than copper wire. At present, except for a small amount of shipment in Anzhou, no other prefectures and counties have delivered similar goods to the discounted grain.

Otherwise, Xu Huai would not have seen him before.

Only two or three hundred kilograms of iron wire is more expensive than copper wire. It is certainly too luxurious to use it as a rope.

Maybe Shefu Family won’t care, after all, the amount is not large, just decoration, but if you want to talk about military uses, as long as you think about the price of copper wire, Fan Zongqi wants to throw this game away.

Can't afford it.

Wu Chihai took the wire, took a small section at the end and wrapped it around his little finger into a ring, saying, "Look at the shape of this thin iron ring that looks like a chain mail, but it is not only thinner and much softer, it is probably difficult to block the sharp blade's chopping," he pulled out the sword, pressed the wire against the base of the blade and slapped it out for a moment, then pulled out a small wedge groove, thinking, "This kind of iron wire can be wound more closely, and may be able to resist the accumulation of ordinary feather arrows to a certain extent, but it will not be better than chain mail..."

Chain mail in the world is mainly forged and quenched with fine iron bars repeatedly

Fire, made into thin rings and buckles and weaved them into armor, the process is extremely complicated and cumbersome. A master maker with superb skills needs to build a set of chain mail, and the energy spent is not slightly lower than that of war armor. The chain mail is preventing long-range shooting, and the melee chopping is not better than that of slashing armor, and the scale armor is better. However, the protection of melee piercing is much worse than that of slash armor, and the manufacturing is even more complicated. It has been rarely seen in the army in modern times.

Everyone was talking about it, wondering what the iron could do in the army, but in the end they were all deterred by the high cost.

Zhuang Yong quickly asked someone to come over, took the wire and said, "Anzhou wire iron, when I was in Bianliang a few years ago, I heard from my father that the method of making sounds nothing difficult. It is similar to gold, silver and copper wire. It is half-melted and perforated and pulled. However, in recent years, except for the iron houses in Anzhou, it is difficult to imitate anywhere else. After all, the flames are not violent enough. Anzhou melting iron pond furnace should have special features, and this is the real secret that is not passed down. Of course, it should not be too difficult for Chu Shan to imitate at this time..."

Shibaliwu Iron House uses the "one-step method" to smel the refined iron. The flame of the furnace can melt the hardest-to-burn cooked iron, and the difficulty in pulling wire iron lies in the furnace flame.

In Zhuang Yong's opinion, Chu Shan had long been able to pull wires, but he didn't think about trying it in the past.

Xu Huai signaled the left and right guards and unrelated people to retreat aside, took the small bundle of iron wire from Zhuang Yong, and asked, "If Chu Shan wanted to make this iron wire, how much would it cost?"

Anything to do without cost is to be a hooligan.

Even if you do not follow the Anzhou method, first use pig iron to smel and forge mature iron (soft iron), and then repeatedly forge it, any skilled craftsman's iron can make thin and long wire, but what is the practical significance of the iron wire made at such a cost?

Even the iron wire made by the Anzhou law is extremely costly.

This game is more expensive than copper wire. If you only need to consume thousands or even tens of thousands of kilograms of iron wire a year, Chu Shan may still be able to grit your teeth and save money, but the problem is that this game is superior to ordinary hemp ropes, and it is far from being so cost-effective.

What Xu Huai is concerned about now is how much can the cost be reduced if Chushan’s unique inverted flame furnace method be used for wire manufacturing?

Of course, Chushan had not prepared iron wires before, and many places are currently speculating that there may be many difficulties that need to be overcome little by little in real trial production. Xu Huai did not expect to be in one step, but instead asked Zhuang Yong to roughly estimate whether there is potential to be tapped here.

“Halving is at least,”

Chushan was specially established to be responsible for coal and iron mining, smelting and other matters. Although it was Zhuang Yong's brother-in-law Shen Lian, who was responsible for the matter, Zhuang Yong was still confident in Chushan's current technical level in smelting. He said,

"This is just a direct imitation at the Shibaliwu Iron Field, but Chu Shan really wants to prepare this thing, and Jieshuai summoned the craftsmen to consider the method, so there should be further reductions..."

Xu Huai nodded, could it be done, how much cost can it be reduced? He also had to convene a person to try it out by hand, and asked again: "How much effort can the pulling method be used for the preparation of chain mail?"

Zhuang Yong was slightly stunned, suddenly looked excited, and when he wanted to praise him, he would suddenly save Xu Huai from retreating without any irrelevant people at this time, which means this

The dialogue at the time is at a certain level to know the detailed secrets. Suddenly, he suppressed the voice and said:

"Jie Shuai doesn't dare to think about others, and he can't think about others - not to mention other things, the old method requires forging the fine iron into an iron bar, and then taking a small iron bar forging hundreds of times to finally become a thin ring. In this step alone, the pulling method used for the preparation of chain mail is much better than the old method..."

"Ahai has clearly mentioned this festival just now, why didn't we think about it?" Fan Zongqi patted his head and smacked his lips, "Are we not as good as Jishuai!"

"Stop praising you, you are too confined to the law of success and too confined to the old law. You dare not think about it if you leave the law of success," Xu Huai said with his hands behind his back. "We should look for rules to follow, but we should also remember that all the law of success and old law can be innovated and broken through. This is the meaning of the head of a hundred feet of pole - the method of warfare, which is still the same..."

The drawing method can be used to make chain mails.

Even if the pulling method is used to make iron wire, the cost may not be reduced quickly, but the cost for making chain mail is definitely much cheaper than the traditional old forging method.

Even though the wire escorted from Anzhou at this time looked much thinner than the iron ring used in the chain mail and was too soft, Wu Chihai thought of these problems before, but was confined to the method of making the chain mail and subconsciously eliminated the possibility of drawing the method of preparing the chain mail, but did not think that some problems could be overcome, and the method of making the system should not be unchanged.

The thickness of the wire can be adjusted completely by the aperture of the pulling plate.

Using iron materials of different specifications for drawing, followed by corresponding quenching and other methods can also change the performance of the wire, which must be soft and hard.

In other words, whether the iron wire has the ability to resist chopping and use it for armor can be achieved through improvements to the existing methods.

Traditional chain mail, thousands of thin rings, each of which requires skilled craftsmanship to be carefully forged by hand. Even if the drawing method is not far from the scope of manual work, the efficiency of the two is by no means the same. Even the drawing method has greatly reduced the technical requirements of the craftsmanship.

The iron rings used in traditional chain mail are thicker, but this is not because the craftsman does not want to forge them thinner and smaller.

The generals and soldiers fighting in armor on the battlefield actually long for the chain mail they have to be more detailed so that they can have stronger anti-cutting and shooting ability.

However, if you want to forge the iron ring smaller and thinner by using the old method, not only does each iron ring take several times of time, but also requires more iron rings to be weave into armor, which will actually increase the manufacturing cost of the chain mail several times.

That is far beyond the practical value of the chain mail itself.

Due to various inconveniences and restrictions, the once-famous chain mail before the Sui and Tang Dynasties has now been gradually eliminated from the battlefield.
