Three Kingdoms

  Chapter 119 Difficult-to-improvement process

  Early in the morning, Fei Qian held up the long spear given to him by Zhang Liao and practiced a shot in a corner of the Huangjiayin courtyard.

This has become a habit of Fei Qian. Anyway, the ancient people did not have mobile phones and computers, and they naturally woke up early when they went to bed early. Although they learned a trick, Fei Qian discovered that this move, from the arms to the shoulders, to the back, and finally to the Almost all legs and feet are exercised, so it is regarded as a way of exercising the body and has been persisted.

  Fei Qian has been living in the guest room of the Huangjiayinyuan for the past few days, and the arrow making has also begun.

Fei Qian was not polite to Huang Chengyan, the Patriarch of the Huang family. Judging from the experience of Fei Qian’s descendants, Huang Chengyan is a kind of bold person. , twitchy, push three resistance four, on the contrary will make Huang Chengyan look down on.

  So Fei Qian directly followed Huang Chengyan's arrangement and settled down. While paying attention to the progress of the arrow project, he was also thinking about some things...

The Huang family is worthy of being a family of toolmakers, and there is a workshop in the other courtyard. More than a dozen craftsmen of the Huang family plus Xiangyang's original ordnance craftsmen, a total of more than 20 people, started manufacturing in the workshop. Even with the craftsmen of Huang's family controlling it, Fei Qian didn't need to spend much thought, and it was operating properly and orderly...

  Pang Tong stayed with him for one day, and ran back the next day. Then he replaced Uncle Fu and brought Fei Qian's usual clothes for changing and a long gun for exercise.

  According to Uncle Fu, after Pang Tong went back, he said with emotion that he finally got rid of Fei Qian's croaking, and that he should read books carefully and enjoy a clean life these days, which almost made Fei Qian's nose crooked.

   In fact, he was mostly joking. After all, Pang Tong said these words in front of Uncle Fu, so he didn’t worry that they would reach Fei Qian’s ears, or he wanted them to be heard by Fei Qian at all...

As for Zaozhi, since he got Fei Qian's books on farming and mulberry, he basically ran out every now and then, looking for some old farmers to verify what he had learned, and he himself opened a small shop behind the wooden house. A piece of land, I don’t know what to plant, it seems to be quite a variety, according to his words, "Spring is the foundation of the year, it needs to be cautious and orderly", so Zaoyi basically squatted in the field during this period …

  Fei Qian finished his practice and took a short rest before going to the workshop.

The friends all have their own affairs, and Fei Qian is not idle. Although it is said that Huang's craftsmen replaced him to manage and supervise, Fei Qian also took a lot of thought to understand the entire production project of this arrow. .

  Today he is going to talk to the craftsmen of the Huang family in the workshop to see if one of his ideas can be realized...

  However, before that, Fei Qian said that he would complain again—

   Who said that there was no assembly line in the Han Dynasty?

  Who said that there was no blast furnace steelmaking in the Han Dynasty?

   Let’s talk about the assembly line first. What is an assembly line? A queue is called an assembly line?

Looking at the arrangements of the craftsmen of the Huang family, there is no need for Fei Qian to say anything. The handling, rough work, etc. are done by apprentices. How many people have arranged a process, and the fine work is done by craftsmen, and there are master craftsmen who control the quality. It is the prototype of the assembly line...

Fei Qian turned around a few times, but he didn't find that there were materials piled up in the process. Basically, they were used whenever they came, and there was no need for Fei Qian to make any regulations on the number of people and materials. The craftsmen of the Huang family had already been well done...

Let’s talk about the iron material used for the arrowheads. Although it was brought from Yiji, it needs to be re-melted and injected in the Huang’s workshop, and then turned into small pieces of arrowheads. Feiqian does not have it in Xiangyang or other places. I haven't seen it clearly, but the craftsmen of the Huang family actually used the "steel frying method" here!

  The "steel frying method" is simply to heat the molten pig iron to a very high temperature, then put the mineral material on the top of the blast furnace, and stir it quickly to get a good material close to steel.

  If this material is subjected to various forging and remelting, higher quality steel can be obtained, but this will consume more manpower...

  Look at the blast furnace of Huang’s family and the fan next to it that uses hydraulic power to blow air, as well as the busy apprentices and craftsmen who come and go, and the high-end ironmaking technology of the Han Dynasty can be seen at a glance...

  Actually, Fei Qian is not very clear, after all, he did not know much about the history of the Han Dynasty in later generations. Since the time of Emperor Hanwen in the Han Dynasty, ironmaking technology has been advancing by leaps and bounds, completely crushing the Xiongnu. The most fundamental reason is that Emperor Hanwen issued an edict to "govern the iron by the people", which means that the ironmaking industry is officially released. If you have the ability to make iron, go for it!

   As a result, in the Eastern Han Dynasty, iron-making blast furnaces as high as four or five meters appeared like the Huangjia blast furnace. According to the Huangjia craftsmen, this one is still small, and there are bigger ones...

The maturity of the steelmaking technology in the Han Dynasty led to the later generations who had no experience in steelmaking and ironmaking. He was basically just a spectator. He just relied on the experience of the later generations in arranging the venue to arrange several slightly conflicting processes in all the workshops. The location of the office has been slightly adjusted to make the whole busy process smoother, but I can't come up with any improvement plan for a while...

  But in the woodworking workshop where arrow shafts were made, Fei Qian found that there seemed to be one place that could be improved——

   is the sawing link.

Originally sawing wood is to put the whole material on the ground and saw it into sections according to the wood grain direction, and then process it. The reason for this is that the whole material is too heavy, and it is too laborious to carry it. Compared with direct decomposition on the ground is relatively easy.

However, Fei Qian considered that he had made a pulley block for the Huang Dou craftsman of the Huang family before, so now it is no longer difficult to lift the whole material and suspend it. ADDED SIMPLE LATHE—

   Such as water saws.

  In the Han Dynasty, there were already many tools for using hydraulic power, such as water cones and hydraulic fans, but there was no water saw. The most fundamental reason was that there was no suitable tool for lifting heavy objects. It is more convenient to saw on the ground...

  So since there are convenient tools for lifting heavy objects, naturally water saws, which are convenient and labor-saving, can be used.

  Besides, the steelmaking technology of the Han Dynasty was already so good, making a large saw is a piece of cake...

  In fact, the working principles of water saws and water cones are similar. They both use hydraulic power to change circular motion into reciprocating motion through mechanical transmission. Since water cones were available in the Han Dynasty, water saws are naturally not a problem.

As expected, when Fei Qian proposed the water saw idea, the craftsmen of the Huang family were very interested. Several people got together to study it a little bit, and according to the equipment samples of the water cone, they made a machine out of it. water saw.

  Then the feeding starts...

   Then just stop and modify...

   Then there was nothing about Feiqian. Several Huang craftsmen who were immersed in inventing and creating new equipment had completely forgotten about Feiqian, and continued to research and improve on their own...

   At this moment, Huang Chengyan, the Patriarch of the Huang Family, stood in the distance, looking at Fei Qian who was calmly getting along with the craftsmen in the workshop, thoughtfully...

   Iron smelting in the Han Dynasty was already very strong. The iron weapons of the Han Dynasty have been completely replaced by bronze wares. That’s why they attacked the Xiongnu in various ways... The author asks for recommendation tickets and collections...
