Chapter 119 Processes that are difficult to improve


    In the early morning, Fei Qian held the spear given to him by Zhang Liao and practiced shooting in a corner of Huangjiayinyuan.


    This has become a habit of Fei Qian. Anyway, ancient people did not have mobile phones and computers, so they would naturally wake up early when they went to bed early. Although he only learned one move, Fei Qian found that this move spread from the arms to the shoulders, then to the waist, and finally to the Almost all my legs and feet are exercised, so I regard it as a way to exercise and stick to it.


    ??Fei Qian has been living in the guest room of Huangjia Yinyuan these days, and the arrow-making business has also begun.


    Fei Qian was not polite to Huang Chengyan, the head of the Huang family. Judging from Fei Qian''s later experience, Huang Chengyan is a more forthright person. Although he likes to joke sometimes, he is also the kind of person who says what he says. If Fei Qian pretends to be polite , coyly, pushing and blocking, but Huang Chengyan will look down on him.


    ?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 indeed a family of weapon makers, and they actually have a workshop in the other courtyard. A dozen Huang family craftsmen plus Xiangyang''s original ordnance craftsmen, a total of more than 20 people, started manufacturing in the workshop. Even with Huang''s craftsmen under control, Fei Qian didn''t have to put much thought into it, and everything was running smoothly 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 frequently used clothes, spears for training, etc.


    ?According to Uncle Fu, after Pang Tong returned, he was very emotional and said that he finally got rid of Fei Qian''s noise. He wanted to read a book and enjoy a pure 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, that is, he was not worried that they would reach Fei Qian''s ears, or he simply wanted these words to reach Fei Qian''s ears...


    As for Zao Zhi, since he got the books on farming and mulberry from Fei Qian, he basically went out every once in a while to find some old farmers to verify what he had learned. He even opened a small shop behind the wooden house himself. I don’t know what kind of things are planted in this piece of land, but it seems that there are quite a variety of things. According to his words, "Spring is the foundation of the year, and it needs to be careful and orderly." So during this period, Zao Zhi basically squatted in the fields. …


    ?Fei Qian finished practicing, took a short rest, and was ready to go to the factory.


    The friends all have their own things to do, and Fei Qian is not idle either. Although it is said that Huang''s craftsman replaced him in management and supervision, Fei Qian also spent a lot of effort to understand the entire production project of this arrow. .


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


    However, before that, Fei Qian expressed that he would like to complain again—


    Who is so special that there was no assembly line in the Han Dynasty?


    ?Who is so special that there was no blast furnace steelmaking in the Han Dynasty?


    Let’s talk about the assembly line first. What is an assembly line? Standing in line is called an assembly line?


    Looking at the arrangements of the Huang family''s craftsmen, Fei Qian doesn''t need to say anything. Apprentices do the handling, rough work, etc., and how many people are arranged for each process. The fine work is done by the craftsmen, and there are master craftsmen who control the quality. This is already This is the prototype of the assembly line...


    Fei Qian turned around a few times, but he didn''t notice that there was any accumulation of materials in that process. Basically, they were all used as they came. There was no need for Fei Qian to specify the number of people or materials. The Huang family craftsmen already knew it by virtue of their experience. Well done...


    Let’s talk about the iron material used for the arrowheads. Although this thing was brought from Yiji, it needs to be re-melted and injection molded by Huang’s workshop and then turned into small pieces of arrowheads. This is not available in Xiangyang or other places. I haven’t seen it clearly, but the Huang family craftsmen here actually use the "fried steel method"!


    Simply put, the "fried steel method" is to directly heat the molten pig iron to a very high temperature, then add the mineral materials above the blast furnace and stir them evenly quickly to obtain a good material close to steel.


    ??If this material is further forged and remelted in various ways, higher quality steel can be obtained, but this will consume more manpower...


    Look at the Huang family''s blast furnace and the fans that use water power to blow the air next to it, as well as the apprentices and craftsmen who are busy and unhurriedly coming and going. The high-end ironmaking technology of the Han Dynasty can be seen at a glance... In fact, Fei Qian is not very clear. After all, he didn''t know much about the history of the Han Dynasty in later generations. Since the time of Emperor Wen of the Han Dynasty, iron-smelting technology has begun to advance by leaps and bounds, completely crushing the Xiongnu. The most fundamental reason is that Emperor Wen of the Han Dynasty issued an edict to "administer iron by the people." That is to say, the iron-smelting matter was fully liberalized by the government, and the common people If you have the ability to make iron, go ahead and make it!


    As a result, during the Eastern Han Dynasty, iron-making blast furnaces with a height of four to five meters appeared like the Huang Family Blast Furnace. According to Huang Family craftsmen, this is still relatively small, and there are even larger ones...


    The maturity of steelmaking technology in the Han Dynasty meant that later generations, who had no experience in steelmaking and ironmaking, basically just became a spectator. He only relied on later generations'' experience in setting up venues to arrange several slightly conflicting processes in the factory. The position of the office has been slightly adjusted to make the whole busy process smoother, but I can''t come up with any improvement plans for the moment...


    But in the woodworking workshop where arrow shafts are made, Fei Qian discovered that there seemed to be one area that could be improved—


    It is the sawing process.


    Originally, when sawing wood, the whole material was placed on the ground and sawed into sections according to the direction of the wood grain, and then processed. The reason for this was that the whole material was too heavy and too laborious to lift. In comparison, it was broken down directly on the ground. is relatively easy.


    But Fei Qian considered that the craftsman Huang Dou of the Huang family had made a pulley set before, so now it is no longer very difficult to lift the whole piece of material and operate it in the air. Moreover, in this way, it can Add a simple lathe—


    For example, a water saw.


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


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


    ?Furthermore, the steelmaking technology of the Han Dynasty was already so good that building a large saw was simply a piece of cake...


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


    As expected, when Fei Qian came up with the idea of ??a water saw, the craftsmen of the Huang family were very interested. Several people got together to study it for a while, and based on the water saw equipment sample, they reconstructed one by dividing three by five and dividing by two. water saw.


    Then the loading starts...


    Then stop and revise...


    ??Then there is nothing more to do with Fei Qian. Several Huang craftsmen who are immersed in inventing and creating new equipment have completely forgotten about Fei Qian and are focusing on their own continuous research and improvement...


    At this time, Huang Chengyan, the head 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, and iron weapons in the Han Dynasty had completely replaced bronze wares, so they were able to deal various critical blows to the Xiongnu... The author asks for recommendations and votes for collection...
