Silver Overlord Chapter 772: The name of the master

After hearing Ou Tiexin ’s invitation, Yan Liqiang smiled and agreed readily. "Haha, I mean that, even if Master Ou does n’t say that, I want to go and see, is this workshop of water and fire machine right in front? ?"

Ou Tiexin pointed to the front, "The workshop that made this water lighter is in front, just a few steps away!"

"Hahaha, Li Qiang, when I heard that you and Master Zhang made a water machine, the iron core made people not far away. I bought three water machine machines from Pingxi County and transported them back. A bunch of craftsmen dismantled and researched the water lighter and began to imitate it. Iron Heart was full of praise for this water lighter! "Luo Yutian also said with a smile, and then looked at Ou Tiexin again," Tiexin you this time If you have any questions, you can ask Li Qiang for advice this time. This is a rare opportunity. Even if other craftsmen want to ask Li Qiang for guidance, they may not be able to move! "

"Hahaha, Brother Luo is very kind. I came here today and I came to learn from it!"

Luo Yutian pointed to Yan Liqiang, "Humble, Liqiang, you are humble again!"

Yan Liqiang smiled ...

"I have a question to ask Master Yan. I heard that the water lighter was originally invented by Master Zhang Yourong, the master of the world's first institution of the Lingshan School. I don't know how adults would think of inventing this thing ? ”O Tiexin asked. In this question, all the artisans who accompanied him showed a listening look. Because of this question, they were also very curious. It just happened that Tiangong Master visited the craftsman city today, so he just wanted to listen to it.

"At that time, Brother Zhang had made a few gadgets by himself, and took it out to discuss it with me. We wanted to make that thing work endlessly without manpower. We discussed it together. At that time, I saw the boiling teapot move up and down under the impact of water vapor. Therefore, I was inspired to find a way to use water and fire to push things endlessly! "

"I admire, admire, I did not expect this weapon like a water and fire machine to actually drink tea and drink it out!" Ou Tiexin and a group of craftsmen listened, and looked at Yan Liqiang with amazing eyes. If Yan Liqiang did not say, None of them would have thought that the water fire machine was actually invented by two powerful men drinking tea together and seeing the teapot boiled. The cowman really was a cowman.

"For the craftsman to the end, he is taking the path of the mastery, knowing the mastery and looking at everything and working together for the benefit of the world and the world of Liufang, you must not underestimate the skill you have in your hands!"

When I heard Yan Liqiang ’s words, Ou Tiexin and a group of artisans were shocked in my heart, feeling that the words were endless, and they were enough for the life of the artisans. Even Luo Yutian could n’t help but praise again, “ Li Qiang said it well!"

A group of people said that after a short walk, they arrived at a large workshop of dozens of acres in a factory that manufactures water and fire machines. There are two big chimneys in the workshop, which are braving the billowing agricultural poplar. , Under the chimney, there is a furnace for melting iron, the hot gas is rolling, and the molten iron is flowing ...

When everyone came, a group of craftsmen in the workshop of the water lighter were busy with the heat, and a man with a head of craftsman quickly ran over with sweat and gave Luo Yutian, Yan Liqiang and Ou Tiexin to salute, Afterwards, they took everyone to visit.

Under the leadership of the craftsman, everyone walked into the workshop, and they just saw a bunch of craftsmen busy. The most important parts of the manufacture of the water machine are all cast, so this workshop The most important process here is casting.

"Master Ou, I think this workshop of water and light machine should have just been expanded?" Yan Liqiang watched while walking. This workshop has a very basic production mode of running water, but Yan Liqiang glanced at it. You can still see the iron-melting furnace and the sand boxes are very new. As for the casting process, let’s not talk about it. It seems that it is not much different from the manufacturing bureau under your own hands, but in fact, in this way In the casting process, some slight differences are enough to bring about a huge impact.

"Adults can also see that there are not many utensils that need to be cast in the former craftsmanship city, so this casting workshop is not large, but to make water and fire machines, the previous casting workshop is not enough, it must be Expansion, the workshop in front of us is newly expanded! "Ou Tiexin said while looking at Yan Liqiang, saying straight away," Although water and fire engines are also produced here, but we follow the parallel cargo machine of the Manufacturing Bureau under the adult The water fire machine made in the same way is not as easy to use as the water fire machine of the Adult Manufacturing Bureau, and there are often problems ... "

"Are there often sand holes in the castings you cast?" Yan Liqiang said casually.

"Ah, lord, do you see it?" Ou Tiexin and the head of a craftsman looked at Yan Liqiang in surprise. Everyone did not expect that Yan Liqiang just came here and glanced at the problem. "We are here It is precisely because there are too many problems with the casting, only one or two of the ten pieces can be used, it is inefficient, and the cost is countless. It is really nerve-wracking. Lord Luo rewarded thousands of gold for a solution, and it has been People can solve..."

"Sand molds are being cleaned over there. Let's take a look ..." Yan Liqiang said, and came to the place where some artisans were dismantling the sand box in the workshop, watching the artisans cleaning the outside of the casting sand mold.

As the sand mold is cleaned, the casting below the sand mold also reveals its original face. This casting is the most critical cylinder part in the water heater. Such a part can only be formed by casting. Knocking and beating is totally impossible.

Yan Liqiang squatted down and looked at the surface of the cleaned cylinder. With a naked eye, he could see a lot of sand holes, which greatly affected the quality of the cylinder. He grabbed a hand The cleaned sand mold was rubbed on the hand, and then stood up. Such a problem was encountered by the manufacturing bureau at the beginning, but was later solved by Yan Liqiang relying on the powerful knowledge reserve ability in the memory.

It is also a sad place for the Han Dynasty. The casting process is actually not complicated. The sand casting process has already existed. In addition to this process, there are more complicated cavity melting wax casting methods, but these are The casting process, which has been used for a long time, is not used to improve production efficiency, but is used to cast those exquisite ceremonial objects and other things, such as various tripods, bells, and funerary objects, these things They are all made of copper or silver. To put it bluntly, it is for the enjoyment and identity of the wealthy and wealthy tribe.

The iron utensils forged by casting that can improve the production efficiency of the whole society are very pitiful. Correspondingly, casting becomes a forging, and finally can only rely on the blacksmith to tinker to create something In the past, the productivity of the entire society has not been improved for a long time, and even with the casting process, it has been stagnant for a long time. The characters who really understand the iron and steel casting are simply a rare existence.

Although there is only one word difference between casting and building, the direction of social development that has evolved since then is far from the world. One is still a farming society, and the other is striding forward in the direction of preliminary industrialization. Dust ...

It is estimated that this craftsman city rarely cast any steel utensils in the past, so now I began to imitate water and fire machines, only to find that although the craft is that craft, it seems uncomplicated and can be mastered, but because of some slight differences, they do n’t care How to make a finished product like the manufacturing bureau.

"Adult, can this problem be solved?"

Yan Liqiang patted the dust on his hands and stood up, "This problem can be solved!"

"Then I do n’t know where the problem is. A group of artisans thought about it for a year and did n’t find out what the problem is?"

"Did you use straw ash and dry sand when gathering sand?"

"Is there any problem?" Ou Tie looked at Yan Liqiang in confusion. "Some of the artifacts cast in the former craftsman city were not the same when they were made as sand molds, but there have been no problems before? "

"Is the object you cast copper or iron?"

"It's copper!"

"The melting temperature of iron is nearly half higher than that of copper, and the weight under the same volume is much larger. Although it is the same sand casting process, you think that the two things are the same. Is it? "

Ou Tiexin's spirit was shocked, and he quickly arched his hand to Yan Liqiang, "Please also enlighten me!"

“The most important reason why cast iron molds produce blisters is that the surface strength of the sand mold drops sharply after dehydration and drying after the sand mold is solidified. There will be trachoma, if you want to avoid trachoma, you can not use straw ash and dry sand when gathering sand, but you must add more humid clay, or mix it with a little paste, and then the sand mold should be pressed and formed. Before casting for half an hour in the lower box, spray the sand mold with water mist, don't let it dry, remember..."

Yan Liqiang said, but the secret method among the craftsmen is worth a million dollars. If it is placed elsewhere, this is definitely the unique skill of the craftsman's family from male to female. I heard Yan Liqiang said this to solve the problem of casting trachoma In this way, Ou Tiexin and the craftsman next to him were overjoyed, and looked at Yan Liqiang one by one with admiring eyes. This day the master craftsman really did not blow it out. Just glance at it to know the problem ...

Luo Yutian also smiled, "Li Qiang, in this way, the water lighter made in this workshop will probably be the same as that made by your manufacturing bureau?"

"Brother Luo wants to hear the truth?"

"What is the truth?"

Yan Liqiang shook his head, "Even if this problem is solved, the water lighter made in this craftsman workshop is only better than yours before, but there will still be a gap compared with the manufacturing bureau, and this gap is very It is difficult to make up, and the gap may become bigger and bigger in the future! "

Ou Tiexin, who was just a little bit happy, was suddenly dissatisfied. "Adults say that, I am afraid they are exaggerating. How can there be such a big gap for the same water and fire machine?"

Luo Yutian also looked at Yan Liqiang with a puzzled expression ...

I saw a short hair sticking to the leather apron worn by Ou Tiexin ~ IndoMTL.com ~ Yan Liqiang stretched out his hand and pinched the hair up, "In my manufacturing department, this hair weighs geometrically , Thickness geometry, volume geometry, I require all qualified craftsmen to be able to fully measure and calculate, if you want to use copper and iron to make a thing like this hair, everyone must also draw the same drawings, did not read Those who have passed this hair can do exactly the same according to the drawings. I do n’t know who can tell me the hair weight geometry, thickness geometry, volume geometry in this craftsman city. If others do it, how many people can make exactly the same thing as this hair? "

A group of craftsmen, including Ou Tiexin, heard Yan Liqiang's question, and then looked at the hair in Yan Liqiang's hand, all of a sudden dumbfounded.

Also the first reaction from Ou Tie Xin, "Does the adult manufacturing bureau have a different measurement system?"

Yan Liqiang nodded, "Yes, I have adopted a brand-new set of weights and measures in the manufacturing bureau and the Qianshan Hall of the Lingshan School. If there is no more precise standard of weights and measures, there will be no greater development. , Everything in the world, for me and other craftsmen, must be measurable! "
