Chang'an City Affairs Visit.

The design department of the company of the Construction Bureau was established in this workshop, which covers an area of nearly half a mile.

Every day, various mechanical parts and new things are developed here, and most of them belong to the category of Gewu, which is very compatible with the name of Wubenbo at that time.

At present, the Bureau of Fabrication and Engineering has an internal and external institute, the inner institute is a theoretical research department, there are officials living in permanent residence, there is a yamen, theoretical research and design, and a part of craftsmen and technicians live here, responsible for manufacturing relatively small objects.

And most of the craftsmen are gathered in the outer place, which is the Dahua Scientific Research Secret Institute, a place on the outskirts of the city near the corner of the foothills of Longshou Mountain, guarded by the forbidden army, as a forbidden place.

At the foot of the mountain, there are rows of workshops and workshops, and in the foothills, many caves have been dug to carry out secret operations and research, making steel parts and large utensils.

On this day, Luo Zhaoyun came to inspect with the Ouchi guards, and Zhou Jin, the waiter of the Construction Bureau, was responsible for leading the team to a hidden cave.

This is a place where iron smelting is tested, and three peculiar vertical bellows are placed in a spacious cave, and a person sits in front of each bellows, making iron by blowing wind.

This kind of wrought iron furnace bellows is the latest research out of the vertical double wooden fan bellows, this vertical bellows is durable and durable, the air volume is large, the strong wind provides sufficient oxygen and improves the temperature of the furnace fire when the wrought iron is wrought, and the temperature of the wrought iron is much higher than that of the iron family of the princely states in the world, so the iron tools created are quite sophisticated.

The purpose of making ironware here is not to make weapons, armor and other needs, but to focus on iron-smelting experiments, such as to study high-quality steel, how to make it harder and tougher, how to make bearings, transmission shafts, parts, etc., and how to resist wear.

Zhou Jin explained: "Your Majesty, please see, this new type of bellows increases the temperature of the molten iron in the furnace, which can remove more impurities, making the iron element easier to desulfurize and form, and the proportion of other elements has also reached the best. ”

Another craftsman named Tang Hong walked over, holding an iron tool in his hand, and bent down to present: "Your Majesty, this is a small gear and worm gear made according to the sketch, and our craftsmen have been studying it together for several days, and finally analyzed the approximate relationship between the number of teeth of the gear and the transmission force, so that we can make a judgment on the size of the power transmission with data." Nowadays, this kind of gear is several times stronger than the previous gear teeth, and the large mechanism gears used in the past are all made of stone, because the iron is brittle and difficult to bite, but now it can be used for a while. ”

Luo Zhaoyun nodded when he heard this, and asked the guard to take it, he took it in his hand, and observed the gear, and sure enough, the weight, surface smoothness, hardness and other properties looked pretty good.

"Well, it looks like it, it's more than twice as good as the iron parts of the Great Sui period!"

Luo Zhaoyun was more satisfied, and asked how other transmission parts were manufactured.

Other craftsmen have brought turbine rods, hammer heads, new vises, iron clips, chains, etc., all of which are made of the latest iron, and the performance is three or four times higher than before.

In the past, iron was brittle, and it was barely used to build weapons, let alone other mechanical equipment, and when it was put into operation, it was easier to break and collapse, but now the quality of iron tools has improved, and for simple hydraulic equipment, it can be assembled and manufactured.

With excellent parts, they can be assembled together to create instruments and equipment.

Luo Zhaoyun has been a bachelor's degree for four years, after all, he has studied mechanical engineering for several years, and he still understands this aspect.

"All the craftsmen and masters have worked hard day and night, designing and manufacturing."

"We are serving the imperial court, thanks to Your Majesty's love for craftsmen, taking salaries, and raising our status, we are all grateful to Your Majesty, this hard work is nothing."

These old craftsmen, between their words, do have a strong sense of gratitude.

"Great country craftsmen, this kind of person is always needed!" Luo Zhaoyun sighed lightly, and then asked: "How long will it take for the first hydraulic machine to come out?" ”

Zhou Jin replied respectfully: "The other parts are relatively large, and they require a large amount of iron, and the casting and moving need to be matched by a lever frame, so the time will be delayed, and the work will be carried out day and night, and the preliminary assembly can be completed after about a month." ”

When Luo Zhaoyun heard this, he was a little happy and said, "Okay! A month later, I visited the site to see how it was commissioned. ”

"Yes." Zhou Jin and his master craftsmen all respectfully applauded.

Luo Zhaoyun sighed: "Although the war is coming to an end, the national defense force must not be ignored at all times, the divine arm bow, Mo knife, cupola cannon, etc., still have to be manufactured, and the armor and weapons must continue to be equipped with our soldiers to defend the frontier after the world is peaceful." If we want to revitalize industrial manufacturing, it is not just a miracle soldier created by a few masters, but large-scale, standardized, mass production, and assembly line operations. ”

"Once this hydraulic forging machine is baked, I want to be like the first hen raised at home, through which it lays eggs, and then continues to hatch more chickens, repeatedly invested, and finally reaches the batch of equipment, all the workpieces are unified standards, I hope that the master craftsmen can formulate a series of parts error standards, sampling inspection, do a good job in data collection, and analyze the stability of mass production."

Zhou Jin and the master craftsmen all fell into deep thought, although they couldn't digest all of His Majesty's words for a while, and some words still felt strange and difficult to understand, but after all, they had worked in this industry all their lives, and they all understood six or seven points, and they all nodded and thought.

Luo Zhaoyun still fully affirmed the research of everyone, worked tirelessly, and devoted himself to industrial research, these old men and middle-aged craftsmen all belong to the Gewu science and technology personnel of Huaguo.

After all, in the Sui Dynasty, not enough attention was paid to industry, and the introduction of these concepts in advance, with the first rays of light, I believe that the development of China will still help!
