Rebirth of the Three Kingdoms: Da Qiao doesn't want to be a widow anymore

According to Qiao Wei's request, Zhu Zhi rectified the original Sijin Farm in Wu County, and also divided the nearby wasteland into it. There are only more than [-] craftsmen in the field, and the craftsmen brought back from Guangling County add up to more than [-].

Qiao Wei calculated the manpower, and then asked Zhu Zhi to find out the most experienced craftsmen in the field, and each of them was assigned a few drawings of the workpiece, and then asked them to make workpiece molds according to the drawings.

To standardize production, molds are essential.

One of the old men just glanced at the drawings, and then asked his own question, "The workpieces drawn by the madam are extremely difficult to make, and the smaller the parts required for the workpiece, the iron must not be used only. It will only work until [-] steel smelting."

Qiao Wei nodded, "The old man is an expert, and he can see the way at a glance. Because the workpiece is small and delicate, after completion, the force it bears is at least ten stones, which cannot be done without a hundred steel smelting."

When Qiao Wei was in the barracks, he also carefully observed the situation of the soldiers during training, and found that due to the effect of the principle of leverage, although the force used by the soldiers was somewhat reduced, the final force needed to be used in order to send the arrow the same distance. On the mechanism, if the hardness of the mechanism is not enough, the frequency of loss and damage will increase.

One hundred steelmaking is a good choice.

Since the mid-Western Han Dynasty, the steel-frying method has gradually become the mainstream of steelmaking, with high production efficiency and good yield.

Refined iron is heated and forged more than 100 times, one forged, one weighed and one lightened, until the weight is not lost, that is, hundreds of steelmaking.This should be the material with the best hardness and quality that can be achieved at present.

The ingenious crossbow cast by Mo's iron shop is all made of [-]-year-old steel.

"But the stock of [-] steel smelting in the field is not enough. If Madam and Captain want to make [-] bows and crossbows, it may not be enough."

Qiao Wei took out some of the drawings, and pointed to the parts marked with fine characters, "These are the ones that need to be forged with refined steel, while the other parts need to be forged with pig iron."

This splicing method is also commonly used by Qiao Wei. Each workpiece bears different forces and functions differently. It does not require the same material for forging.

Part of the shell can also be completely replaced by wood, which can reduce part of the weight, while ensuring the range and durability, reduce the burden on soldiers, and prolong the durability of soldiers in combat.

"So, it may not be possible."

Qiao Wei had no choice but to ask, "Then how long can the iron and hundred-smelting steel in the field last?"

"Currently, the reserves in the field are less than [-] shi for pig iron, and less than half for [-] steel smelting."

One stone in the Eastern Han Dynasty is equivalent to 29.76 kilograms. In conversion, it is indeed not much. The combination of pig iron and [-]-year-old steelmaking does not even have a ton.

The production of 4 ingenious crossbows, even according to modern standards, is about [-] kilograms, and the Nushen is made of wood, bamboo and other materials, and at most it can only produce less than [-] sets of workpieces.

Qiao Wei couldn't help being a little puzzled, and asked Zhu Zhi, "Why is there no material reserve in the venue?"

Logically speaking, Sijinchang in Wu County should be regarded as a relatively large-scale weapon reserve for the Jiangdong Army.

Zhu Zhi smiled bitterly, "Because there is no iron ore to mine in Jiangdong."

Qiao Wei suddenly remembered that the iron ore mining technology in the Han Dynasty was limited, and the mainstream iron smelting technology was mainly concentrated in the five capitals, namely Handan, Nanyang, Shujun, Luoyang, and Linzi.

Among them, Handan has the most abundant iron ore, and Nanyang is a technological stream, but no matter which one has nothing to do with Jiangdong.

Because the development of the iron smelting industry is concentrated in the five capitals, correspondingly the most developed iron smelting industry and the most skilled talents will also be concentrated in the five capitals.

What a desperate fact this is.No wonder the two brothers, Sun Ce and Sun Quan, are so obsessed with seizing the opponent's weapons every time they win a battle. Their feelings are due to the lack of backup, and they are all their own if they can grab an extra piece of equipment.

Qiao Wei thought for a while, and gave an answer, "No matter whether there is enough iron or stone in the end, let's do what can be done in Si Jinchang first."

A worker is a worker, a worker is a soul, and a worker is responsible for burning his soul from heaven to earth.

The instructions issued by the boss above must be followed if there are conditions, and if there are no conditions, they must be followed if conditions are created.Under limited conditions, even if you can't do anything, you can't do nothing.

She gave Zhu Zhi a stack of thick proposals, which were really handwritten manuscripts, something she had thought about doing when she was in the barracks.

"In the Sijin factory, according to the time required for the process and the difficulty of the process, a group of three to ten people can complete a process, and an experienced craftsman is responsible for the quality inspection."

Zhu Zhi flipped through the thick stack of yellow paper, read the words on the paper in a low voice, and then asked curiously, "What is quality inspection?"

"Quality management and inspection." Qiao Wei adopted the interpretation of the Chinese classics very officially, and then added his own explanation, "It is whether the proofreading is consistent with the requirements of mold forming and the measurement of drawings."

"By the way, Captain Captain, please familiarize yourself with all the contents of this booklet within three days, and then teach it to Si Jincheng in Sijinchang, and then organize and arrange to promote the trial work in Sijinchang."

Looking at the thick yellow paper, Zhu Zhi couldn't help but widen his eyes, "Ma'am, you mean..."

"Yes, if Lord Captain thinks that time is too much, then it will take two days..."

"what?"

Zhu Zhi was taken aback by Qiao Wei's style of doing things as soon as he thought about it, "This subordinate doesn't mean that."

Sun Ce and Sun Quan both wrote back, asking Zhu Zhi to fully assist Qiao Wei in rectifying Sijinchang, otherwise Zhu Zhi would have jumped out to question it with his personality.

"The subordinate just doesn't know what Madam's idea is, so the subordinate can help arrange it."

Qiao Wei said, "You open the fifth page of the manual No. 30. First, you need to engrave the mold. The drawings of the mold have been distributed to the head craftsmen just now, and the requirements have also been clearly stated. The tolerance must not exceed one tenth of an inch."

That is 3mm.

"Secondly, it is grouped according to the process. Each group is responsible for the continuous casting of a process. Forging tube forging, iron melting tube iron melting, and pouring tube pouring. Each group performs its duties without interfering with each other."

"The last thing is to set up quality inspection, sample inspection and sit together according to the responsibility system. Whoever's process fails to meet the requirements, the whole team will rework."

Qiao Wei also pointed out the most important task at present, "Looking for iron ore, you can also purchase large quantities of pig iron or iron stone."

Zhu Zhi thought to himself, other things are fine, but the iron ore may not be easy to find, and now all the mining industries of the imperial court are taken over by the powerful princes from all walks of life, where is it their turn!
Qiao Wei said, "Actually, I have two possible paths in my mind."
