Silver Overlord - Chapter 804

[Chapter 772 The name of the master craftsman]

Hearing Ou Tiexin’s invitation, Yan Liqiang laughed and agreed readily, “Haha, that’s what I mean, even if Mr. Ou doesn’t say it, I want to go and see it. Is this water and fire machine workshop right in front?”

Ou Tie Xin pointed to the front, “The workshop that makes this water fire machine is right in front of you, and it’s just a few steps away!”

“Hahaha, Li Qiang, when I heard that you and Master Zhang made a water fire machine, Tie Xin made people feel uncomfortable. Thousands of miles away, I bought three water lighters from Pingxi County and sent them back to the escort agency. Once I came back, I took a group of craftsmen to dismantle the water heater and began to copy it. Tie Xin is full of praise for this water heater. !” Luo Yutian also said with a smile, then looked at Ou Tiexin again, “Tie Xin, if you have any questions this time, you can ask Li Qiang for advice this time, this is a rare opportunity, even if other craftsmen want to invite gifts If

you are forced to give guidance, you may not be able to ask for help!”

“Hahaha, Brother Luo is polite, I came here today to gain insight!”

Luo Yutian pointed at Yan Liqiang, “Humble, Liqiang, you are humble again!”

Yan Liqiang smiled…

“I have a question that I would like to ask Master Yan for advice. I heard that this water-fire machine was invented by the master and Zhang Yourong, the world’s number one organ master of the Lingshan School. I wonder how the master would have thought of inventing it. This thing?” Ou Tiexin asked, and when he asked, all the craftsmen accompanying him showed their expressions of listening. Because of this question, they were also very curious. It just happened that the master craftsman of Tiangong visited the Craftsman City today, so he wanted to listen.

“At that time, Brother Zhang made a few gadgets with his own hands, and took them out to discuss with me, so that the thing could run endlessly without manpower. We discussed it together. The lid of the boiling teapot moved up and down under the impact of water vapor, so I got inspiration and found a way to use the power of water and fire to push things to run endlessly!”

“Admiration, admiration, I didn’t expect that a sharp weapon like this water and fire machine was actually made out of tea!” Ou Tiexin and a group of craftsmen listened, and they all looked at Yan Liqiang with amazement. If Yan Liqiang didn’t say it, they would not I would have thought that this water and fire machine was actually invented by two great experts drinking tea together and seeing the teapot being boiled.

“To the end of a craftsman’s life, all you take is the way of examining things, examining things to gain knowledge, observing all things and doing things together, benefiting the world, and immortalizing the world, you must not underestimate your own ability!”

Hearing Yan Liqiang’s words, Ou Tie Xin and the other craftsmen were shocked. They felt that these words had infinite charm and could be used for a lifetime by a craftsman. Even Luo Yutian couldn’t help but praised when he heard it, “Li Qiang said it well!” The

group After saying that, after walking for a while, I came to a large workshop covering dozens of acres. This workshop is a workshop for making water and fire machines in the artisan city. There are two large

chimneys

in the workshop.

, is the furnace that melts iron, the steam is bubbling, the molten iron is flowing…

When everyone came, a group of craftsmen in the water and fire machine workshop were busy with work, and a man with the appearance of a craftsman ran over quickly, sweating profusely, and gave Luo Yutian, Yan Liqiang, Ou Tiexin and others saluted, and then took everyone to visit.

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

“Master Ou, I think this water and fire machine workshop has just been expanded, right?” Yan Liqiang watched as he walked. There was a very basic flow production mode in this workshop, but Yan Liqiang glanced at it and could still see it. The furnace for melting iron and the sandboxes are all 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 my own, but in fact, in such a casting process. , some small differences are enough to have a huge impact.

“Your Excellency can also see that there are not many objects that need to be cast for the things produced in the artisan city in the past, so the foundry workshop is not big, but to make water fire machines, the previous foundry workshop is not enough, and it must be expanded. This workshop is newly expanded!” Ou Tiexin said while looking at Yan Liqiang, and said completely straight, “Although there are also water-fired machines here, we build them according to the appearance of the parallel machines of the Manufacturing Bureau under your command. The water fire machine that comes out 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 poured?” Yan Liqiang said casually.

“Ah, sir, can you see it?” Ou Tiexin and a group of craftsmen looked at Yan Liqiang in surprise, but no one thought that Yan Liqiang just came here to take a look, and immediately found the problem, “We are here precisely because There are too many problems with the castings. Only one or two of the ten pieces can be used, which is inefficient and expensive. It is really nerve-racking. Lord Luo rewarded thousands of taels of gold to seek a solution, but no one has been able to solve it. “…”

“The sand molds are being cleaned over there, let’s go and have a look…” Yan Liqiang said, and came to the place where several craftsmen were dismantling the sand boxes in the workshop, watching the craftsmen cleaning the outside of the castings. sand mold.

As the sand mold is cleaned, the casting under the sand mold also reveals its original appearance. This casting is the most critical cylinder part in the water fire machine. Such a part can only be formed by casting. Not at all.

Yan Liqiang squatted down and looked at it. On the surface of the cleaned cylinder, with the naked eye, you could see a lot of sand holes, which greatly affected the quality of the cylinder. He grabbed a handful of the cleaned cylinder. Sand mold, rubbed it on his hand, and then stood up. This kind of problem was encountered in the manufacturing bureau at the beginning, but it was later solved by Yan Liqiang relying on the strong knowledge reserve ability in memory.

Speaking of which, it is also a sad part of the Han Empire. The casting process is actually not complicated. The process of sand casting has been around for a long time. In addition to this process, there are also more complex cavity melting wax casting methods, but these casting processes, The place where it has been used for a long time is not to improve production efficiency, but to cast all kinds of exquisite and exquisite ritual utensils, such as various tripods, bells, and funeral objects. Bronze or silver is used for casting, to put it bluntly, it is for the rich and powerful family to enjoy and show their status.

And the iron and steel utensils used for casting and forging that can improve the production efficiency of the whole society are pitiful. Accordingly, casting has become forging. In the end, we can only rely on blacksmiths to forge something. The productivity of society has not been improved for a long time, and even the casting process has been stagnant for a long time. People who really understand steel casting are simply rare.

Although there is only one word difference between casting and forging, the development direction of the society that has evolved later is very different. One is still a farming society, while the other is making great strides in the direction of preliminary industrialization.

It is estimated that this craftsman city rarely cast any steel artifacts before, so now I started to imitate the water fire machine, only to find that although the craft is that craft, it seems that it is not complicated and can be mastered, but because of some subtle differences, they still make it anyway. Not a finished product like a manufacturing bureau.

“Sir, can this problem be solved?”

Yan Liqiang clapped the dust on his hands and stood up, “This problem can be solved!”

“Then I don’t know where this problem came from. Our group of craftsmen have been thinking about it for a year and haven’t found it yet. What’s the

problem?”

“Did you use straw ash and dry sand when gathering sand?”

“Is there any problem?” Ou Tiexin looked at Yan Liqiang doubtfully, “Some of the utensils cast in the Craftsman City before, do This is not the case with sand molds, but there have been no problems before?”

“Is the utensil you cast made of copper or iron?”

“Is it copper!”

“The melting temperature of iron is nearly half higher than that of copper, and the weight under the same volume is also much higher. Although it is the same sand casting process, do you think the sand accumulating things used for both are the same?

Ou Tiexin was shocked, and quickly surrendered to Yan Liqiang, “Please enlighten me!”

”

The most important reason for the occurrence of blisters in the cast iron mold is that the surface strength of the sand mold decreases sharply after it is solidified and dehydrated and dried, and the surface sand is very easy to grain. It is eroded by the heavier and hotter molten iron and falls into the molten iron, which will cause blisters. If you want to avoid blisters, straw ash and dry sand cannot be used when gathering sand, but clay with higher humidity must be added, or Mix a little paste and stir together, and then the sand mold should be re-formed, and before the sand mold is cast in the lower box for half an hour, the sand mold should be sprayed with water mist, don’t let it dry, remember…”

Yan Liqiang said, but The secret method among the craftsmen is worth thousands of gold. If it is placed elsewhere, this is definitely the unique skill of those craftsmen’s families to pass on men and not women. When Yan Liqiang said this solution to the trachoma in castings, Ou Tiexin and the next one did it. The craftsmen and craftsmen were all overjoyed, and looked at Yan Liqiang with admiration. The master craftsman really didn’t blow it out. Just one glance and he knew the problem…

Luo Yutian also laughed, “Liqiang, such a thing. Come on, the water and fire machines made in this workshop are probably the same as those made by your manufacturing bureau?”

“Brother Luo, do you want to hear the truth?”

“What is the truth?”

Yan Liqiang shook his head, “Even if it’s resolved. This problem, the water fire machine made in this Craftsman City workshop is only better than your previous ones, but compared with the manufacturing bureau, there is still a gap, and this gap is very difficult to make up, and the gap may become more and more in the future. Great!”

Ou Tiexin, who was still a little happy just now, was suddenly dissatisfied, “My lord, I’m afraid I’m exaggerating. How can there be such a big gap between the same water and fire machine?”

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

Seeing that there was a short hair stuck to the leather apron that Ou Tiexin was wearing, UU read www.sonicmtl.

com Yan Liqiang stretched out his hand and pinched the hair, “In the manufacturing bureau under my command, the weight of this hair is geometric, its thickness is geometric, and its volume is geometric. I require all qualified craftsmen to be able to measure and calculate it completely. If it is made of copper and iron. For a thing that is the same as this hair, everyone must draw the same drawing. People who have never seen this hair follow the drawing and can make the exact same thing. , who can tell me the weight geometry, thickness geometry, volume geometry of this hair, you can draw the drawings and let others do it, how many people can make something exactly the same as this hair?”

Including Ou Tiexin When a group of craftsmen heard Yan Liqiang’s question, and then looked at the hair on Yan Liqiang’s hand, they were all dumbfounded.

It was Ou Tiexin who reacted first, “Could it be that there are different measurement systems in your manufacturing bureau?”

Yan Liqiang nodded, “Yes, my manufacturing bureau and Lingshan Pai Qianjitang have already adopted a brand new set of metric systems.

Weights and measures, organs and objects are together, if there is no more accurate standard of weights and measures, it will be difficult to have greater development, all things in the world, for craftsmen like me, must be measurable!”
