Silver Overlord

When I heard the invitation of the European iron heart, Yan Liqiang smiled and agreed to it. “Haha, I have this intention. Even if I don’t say it, I want to see it. Is the workshop of this water heater in front?”

The European iron heart pointed to the front. “The workshop for making this water lighter is in front, and it will be a few more steps!”

“Ha ha ha, Li Qiang, when I heard you and Master Zhang got the water lighter, the iron core was so far away that I bought three water heaters from Pingxi County and shipped them back. When I came back, I took a bunch of craftsmen. I took the water lighter out of the study and began to copy it. The iron heart is full of praise for this water lighter!” Luo Yutian also said with a smile, then looked at the iron heart, “I have any problems with you this time.” This time, I can ask for advice from Li Qiang. This is a rare opportunity. Other artisan camps may even want to ask for a gift, and they may not be able to move!”

“Ha ha ha, Luo Laoge is polite, I am here today, it is also a long-term experience!”

Luo Yutian pointed to Yan Liqiang. “Modesty, courtesy, you are modest!”

Yan Liqiang smiled…

“I have a question I would like to ask Yan Elder. I heard that this water lighter was originally invented by Zhang Yourong, the world’s first master of elder and Lingshan Faction. I wonder how the elder would have thought of inventing this thing?” The iron heart asked, he asked, and the craftsmen who accompanied him showed a look of listening. Because of this problem, they were also very curious. Just today, Tiangong masters came to the artisans, so they wanted to listen.

“At that time, Zhang Laoge had personally made a few gadgets and took it out to discuss with me. I wanted to let it run without human resources. We discussed it together. Once I was cooking tea, I watched it. In the boiling teapot, under the impact of the water vapor, the teapot cover swayed up and down, so I got the inspiration and found a way to push things to work with the power of water and fire!”

“Appreciate, admire, I didn’t expect such a weapon like a water heater, actually drinking tea!” Ou Tiexin and a group of craftsmen listened, and all looked at Yan Liqiang with amazement, Yan Liqiang, if they didn’t say, they I wouldn’t have thought that the water heater was actually two great people who had a cup of tea together and saw that the teapot was burned and invented. The cowman was really a cow.

“For the end of the craftsmanship, all the way to go is to find the way of the things, to know things, to see all things and to work together, to benefit the world, to live in the world, you can not despise the skills in your hands!”

When I heard Yan Liqiang’s words, the European iron heart and the craftsmen all felt a shock, and I felt that the words were endless. It was enough for the craftsmen to be used for life. Even Luo Yutian listened, and could not help but praise again. well said!”

The group said, if you didn’t walk for a while, you went to a workshop that built a water and light machine in a large workshop that occupies dozens of acres. There were two big chimneys in the workshop, and they were braving the farm Yang, the chimney. Below, is the melting iron stove, hot air rolling, hot metal flow…

When the people came, a group of artisans in the workshop of the water-heater were busy in the air, and a man with a head-like appearance rushed over and sweated to Luo Yutian, Yan Liqiang, and the European Iron Man and others. Take a tour of the crowd.

Under the leadership of the craftsman, everyone went to the workshop and just saw a bunch of craftsmen busy. The most important parts of the manufacture of this water heater were cast, so the most important thing in this workshop. The process is casting.

“Ou Elder, I think the workshop of this water heater should have just been expanded?” Yan Liqiang looked at it while walking. There was a very primitive production mode in this workshop, but Yan Liqiang looked at it, still You can see the iron furnace, and the sand boxes are very new. As for the casting process, it will not be said. It seems that there is not much difference with the manufacturing bureau of your own, but in fact, in such casting In the process, some subtle differences are enough to bring about huge impact.

“The elder also saw that the things produced in the former artisans need not be cast much, so the casting workshop is not big, but to create a water heater, the previous casting workshop is not enough, and it must be expanded. This workshop is a new expansion!” Ou Tiexin said as he looked at Yan Liqiang and said straight and straight. “Although the water heater is also produced here, we follow the elder’s parallel machine.” The water heaters that are made are not as good as the water heaters of the elder manufacturing bureau. They often have problems…”

“Is there a sand hole on the castings you poured out?” Yan Liqiang said casually.

“Ah, elder, do you see it?” Both the European iron heart and the dry head looked at Yan Liqiang with surprise. Everyone did not expect Yan Liqiang to just come here and look at the problem. “We are here.” Because there are too many problems in casting, only one or two of the ten can be used, it is inefficient, and it is costly. It is really nerve-wracking. Luo Elder rewards thousands of gold for seeking solutions, and has never been Can solve…”

“There is cleaning up the sand type over there. We used to look at it…” Yan Liqiang said, and came to the workshop where several craftsmen were taking out the sandbox and watching the craftsmen clean the sand outside the casting.

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

Yan Liqiang looked down, the surface of the cylinder that was cleaned up, with a naked eye, you can see a lot of sand holes, which greatly affects the quality of the cylinder. He grabbed it with his hand and cleaned it down. The sand type was placed on the hand and then stood up. This problem was encountered by the manufacturing bureau, but it was later solved by Yan Liqiang’s powerful knowledge reserve in memory.

It is also a sad place for Great Han Empire. The casting process is not complicated. The sand casting process has long been available. In addition to this process, more complex cavity melt wax casting methods are also available, but these casting processes The place that has been used for a long time is not used to improve production efficiency, but to cast things such as exquisite rituals, such as various cauldrons, bells, and funerary objects. Casting with copper or silver, to put it bluntly, is to enjoy and demonstrate the identity of the powerful fish.

The steel utensils that are forged and forged in the production efficiency of the whole society are pitiful. Correspondingly, the casting becomes a creation. In the end, it can only rely on the blacksmith to create something. The productivity of the society has not been improved for a long time. Even with the casting process, it has been stagnant for a long time. The people who really understand steel casting are just like the rare ones.

Although casting and building are only one word difference, the social development direction that has evolved later is far from one another. One is still farming society, while the other one is striding forward in the direction of initial industrialization. The last one is riding…

It is estimated that this city has rarely cast any steel utensils before, so now I have begun to imitate the water heater, only to find that although the craft is the craft, it seems to be uncomplicated and can be mastered, but because of some subtle differences, they are created anyway. Not the same finished product as the manufacturing bureau.

“elder, can this problem be solved?”

Yan Liqiang patted the dust on the hand and stood up. “This problem can be solved!”

“I don’t know where this problem comes from. We have a group of artisans who have thought about it for a year and have not found out the problem?”

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

“Is there any problem?” Ou Tiexin looked at Yan Liqiang with a puzzled look. “When some of the artifacts cast in the artisans were used to make sand molds, this was not the case, but had there been any problems before?”

“Is the artifact you cast copper or iron?”

“It’s copper!”

“The melting temperature of iron is nearly half higher than the melting temperature of copper. The weight in the same volume is much larger. Although it is the same sand casting process, do you think that the things used in the sand are the same? ”

The spirit of the European iron heart shocked, and quickly turned to Yan Liqiang, “Please elder enlighten me!”

“The most important reason why the cast iron mold produces sand holes is that the surface strength drops sharply after dewatering and drying after the sand mold solidifies. The surface sand particles are easily washed by the heavier and hotter molten iron into the molten iron, so that the sand holes are generated. If you want to produce no sand holes, you can’t use straw ash and dry sand when you gather sand. You must add more clay with a higher humidity, or mix with a little paste, then the sand mold should be re-formed and cast in the sand box. Before half an hour, spray the water spray on the sand, don’t let it dry, remember…”

Yan Liqiang said, but the secret method among the craftsmen is worth a lot of money. If it is placed elsewhere, this is definitely the craftsmanship of the craftsmen’s house. It is said that Yan Liqiang said this solution to solve the sandblasts of castings. The European iron heart and the artisan craftsmen next to them were all overjoyed. They looked at Yan Liqiang with a adoring look. This day, the great craftsman really didn’t blow it out. Just look at it and know the problem…

Luo Yutian also laughed. “Rite is strong. In this way, the water and light machine created in this workshop will probably be the same as the one made by you.”

“Does Luo want 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 workshop is just better than yours, but there is still a gap compared with the manufacturing bureau, and this gap is very difficult to make up. The gap in the future may be getting bigger and bigger!”

Just a little happy, the European iron heart was suddenly convinced. “Elder said so, I am afraid that it is exaggerated. How can there be such a big gap in the same water heater?”

Luo Yutian also looked at Yan Liqiang with a puzzled look…

Seeing that the leather apron worn on the iron heart was attached with a short hair, Yan Liqiang reached out and squeezed the hair. “In my underarm manufacturing, this hair has a geometric weight, a fine geometry, and a volumetric geometry. I ask all qualified craftsmen to be able to fully measure and calculate. If you want to make something like this hair with copper and iron, everyone must also draw the same drawings, people who have not seen this hair. I can do exactly the same thing according to the drawings. I don’t know in this city, who can tell me the weight of the hair, the geometry of the hair, the geometry of the volume, you draw the drawings, let others do it, can have How many people can make exactly the same thing as this hair?”

A dry craftsman, including the European iron heart, heard the question of Yan Liqiang, and then looked at the hair of Yan Liqiang’s hand, all of a foolish look.

Or the first reaction of the European iron core, “Is there a different measurement system in the manufacturing department of Elder?”

Yan Liqiang nodded. “Yes, I have adopted a new set of weights and measures in the Manufacturing Bureau and the Lingshan Faction.” Without a more accurate measurement and measurement standard, it is difficult to have greater development. Everything must be measurable for me and other craftsmen!”
