Three Kingdoms

  Chapter 567 Breakthrough thinking mode

   Fei Qian squatted on the ground, using wooden sticks to pull item by item on the ground, just like a rich man calculating how much grain he had in his home.

   In the first step, the problem of mining technology is not too big. It has not yet reached the point of digging deep wells. Surface mining is relatively easy. It is not a problem to come out of iron ore and crush it here. The thing of water mill has been around for a long time;

  The second step is to mix in lime powder, which is not a problem, and the amount should be adjusted according to the condition of the molten iron;

  The third step is to remove carbon from the pig iron to form a rough steel ingot. This has steel frying technology, hydraulic wind exhaust, and even overcooked steel filling technology. At this stage, it is enough;

The fourth step is to forge the steel to further remove various impurities, increase the strength, toughness and hardness of the steel, and then trim the steel ingots into various required equipment. Some labor is spent here...

  Add water forging equipment!

  First remove the manpower consumption of the rough beating. As for the fine beating, let’s see if there is any progress in the follow-up. In the Han Dynasty, there were water cone carts and water drains. In fact, the operating principles of these devices are similar, but no one has applied them to the wrought iron industry for the time being, so only a little improvement is needed, and the problem is not too big.

   But this brushed workmanship…

   It's really hard to do, and I have no clue at all.

  Huang Yueying came over quietly carrying a food box, and squatted aside with Fei Qian, blinking her big eyes at the things Fei Qian scribbled on the ground.

   "Lang Jun, what are you going to do?" Huang Yueying squatted beside Fei Qian, resting her elbows on her knees, cupping her chin, and whispered.

  Fei Qian frowned and said, "Drawing, or drawing..."

  Huang Yueying blinked, repeated a sentence in a murmur, and then said, "Lasi, what are you drawing?"

   "Iron wire, how can it be simpler?" Fei Qian drew a few molds on the ground, but found that these molds seemed to require higher technology to make, so he was very confused, as if he had reached a dead end.

If you want to do wire drawing, you must have tools, and this tool requires higher technical support. To develop these basic technologies including lathes, and in turn require more cutting-edge materials, it is simply an endless challenge. The vicious circle can never get out.

  Huang Yueying didn't understand what Fei Qian was thinking, but it didn't hinder her desire to help Fei Qian, so she tilted her head and thought for a while, then suddenly stood up, stomped and ran away.

Fei Qian didn't care about Huang Yueying's movements at all. He was mainly worrying about how to add to the simple mechanical craftsmanship of the Han Dynasty, and many of the technologies and methods he knew of later generations had not been realized in the Han Dynasty for the time being. That's the most troublesome problem.

  I know what to do, but I just can’t do it. The conditions are not enough. I saw the technology tree, but I just can’t click it. This kind of depression makes Feiqian almost crazy.

  Huang Yueying ran back again. Behind Huang Yueying followed a middle-aged craftsman, holding a big rattan box in his hand, and came to Fei Qian.

   "This is..." Fei Qian was a little puzzled.

   Huang Yueying didn't stop breathing, and urged the middle-aged craftsman to quickly demonstrate.

The middle-aged craftsman smiled naively, first bowed to Fei, then sat down on the ground without saying a word, put the rattan box aside, opened it, and took out some small hammers and clips from inside and some iron sheets, and even a little stove or something...

The middle-aged craftsman skillfully set up a charcoal fire in the small stove, then took a small pot and put it on the fire, took out a small piece of silver, and then burned it. Although the melting point of silver is not too high, it is still After burning for a while, fortunately, the silver nugget was not big, and gradually began to melt under constant heating.

  The middle-aged craftsman took a few iron sheets, and there seemed to be some grooves on the iron sheets, and then poured the molten silver liquid in the crucible onto these iron slots.

  The silver liquid left the fire source, cooled down quickly, and formed long and thin silver rods on the iron tank...

   "Hmm..." Fei Qian pinched the thin, fluffy beard on his chin, a little understanding of Huang Yueying's intentions, and began to think about it in his heart.

The middle-aged craftsman didn't stop, he took a small hammer, and while the silver was not completely cold, he beat it carefully again, obviously to make the silver rod more even, and then waited for the silver rod to cool to a certain extent, I took out one of them, and took another thick iron plate. There seemed to be quite a few small eyes on the iron plate...

this is…

   Brushed board!

   Fei Qian felt as if he had been knocked on his mind by something, yes, drawing board! This most primitive hand-drawn mold is an important tool for making golden jade clothes in the Han Dynasty!

   Otherwise, how could such thin silver and gold threads be knocked out one by one?

Sure enough, the middle-aged craftsman sharpened the silver rod a bit, and then put it on the drawing board. Using a small pliers, he pulled it out little by little, and then changed it to a smaller round hole. , originally a thin silver rod, has now become a circle of silver wire...

  Fei Qian squatted in front of the middle-aged craftsman, picked up the circle of tiny silver wire...

   That's right, why do I always think about getting things done in one step?

Separate the steps of wire drawing. First, use the mold to make thin iron rods. This is no problem. Then use the wire drawing board, borrow water conservancy transmission, and move back and forth to draw the iron rods into wires little by little, and then it is as thin as After a certain level, it can even be further refined with a simple device such as a pulley roller...

Of course, there are still some problems, such as the melting point of iron is higher than that of gold and silver, and at this stage there is no material with a higher melting point and a harder shape than iron to act as a drawing board, but this is not a big problem, heating and cooling are originally As a compulsory course for blacksmiths, heating is not much to say. Coking coal is enough to provide enough heat. If it is not possible to cool, use the cooling method of later generations of computers. Whether it is air-cooled or water-cooled, there is no particularly big problem.

  Many things are like this. When you have no ideas, you don’t know how to deal with them. But after you have a path, you only need to deal with the difficulties that will arise around this path, and you can hope to achieve your goal.

  Fei Qian finally laughed, stood up, bowed his hands to the middle-aged craftsman, thanked him, then turned to Huang Yueying and said, "Thank you too..."

  Huang Yueying was a little happy, but also a little embarrassed. She twisted a bit, and suddenly remembered something, and blurted out: "Oh, it's broken, the soup is cold now..."

   In addition, there is a word for steel in Indian Sanskrit, "Cinaja", which means "Qin Disheng", and Qin refers to China, which shows the influence of Chinese steel on India. In 1961, a steel knife was unearthed from an ancient tomb in Nara Prefecture, Japan, and the inscription indicated that it was made during the Zhongping period of the Eastern Han Dynasty (184-189). "World History" edited by Cui Lianzhong believes that after the Eastern Han Dynasty, China's iron and steel smelting and casting technology was introduced to Japan, and the general route was that it was introduced to Kyushu through the southern part of the Korean Peninsula and Tsushima Island; and then spread to Japan from west to east with Kyushu as the center most of the regions.

   The British science historian Bernard said that China "has been one of the great centers of human civilization and science for many centuries" ("Science in History: A Preface to the Chinese Translation", reprinted by Science Press in 1981). The same is true.

   However, this process of agricultural culture and technological advancement was interrupted several times during the integration of the ethnic minorities to establish an official caliber...
