Chang'an City Affairs visits.

The Construction Bureau established the company's yamen and design department, and the area has reached nearly half a litre.

Various mechanical parts, new things, etc. are being developed here every day, most of which belong to the category of investigating things, and are very consistent with the name Wubenfang at that time.

The Construction Bureau currently has an internal and external office. The internal office is a theoretical research department. There are officials who often live in it and a yamen for theoretical research and design. Some craftsmen and technicians live here and are responsible for manufacturing relatively small objects.

Most of the craftsmen gathered in the outside world, which was the Dahua Research Secretariat. The suburb of the city was near the corner of the foot of Longshan. They were guarded by the imperial guards and regarded as the forbidden area.

At the foot of the mountain, there are rows of workshops and workshops. In the foot of the mountain, many caves have been dug out to conduct secret operations and research, and to manufacture steel parts and large utensils.

On this day, Luo Zhaoyun brought the Grand Inspector to inspect. Zhou Jin, the assistant minister of the Construction Bureau, was responsible for leading the team to a hidden cave.

This is a place for iron smelting tests. Three unique vertical bellows are placed in a spacious cave. There is a person sitting in front of each large bellows, blowing the air and smelting iron.

This wrought iron furnace blower is the latest research vertical double-wood fan bellows. This vertical bellows are strong and durable. The strong wind power provides sufficient oxygen when wrought iron and increases the temperature of the furnace fire. The temperature during wrought iron is much higher than that of the iron smelting families of various vassal states in the world, so the iron tools are created quite exquisite.

The purpose of making iron tools here is not to make weapons, armor, etc., but to focus on iron smelting tests. For example, to study how high-quality steel can be harder and tougher, to make bearings, transmission shafts, parts, etc., and how to wear-resistant.

Zhou Jin explained: "Your Majesty, please see, this new bellows increase the temperature of the melting iron in the furnace, remove more impurities, make iron elements more easily desulfurized and molded, and the proportion of other elements is also the best. The latest iron parts made of the latest iron parts are much higher than the previous iron tools."

Another craftsman named Tang Hong came over, holding an iron tool in his hand, bent over and presented: "Your Majesty, this is a small gear and worm gear made according to the sketch. The craftsmen and we have been studying it over and over for several days. Finally, we analyzed the rough relationship between the number of gears and the transmission power, so that we can make a transmission with data to judge the size of the force. Now this kind of gear is several times stronger than the previous gear teeth. The large-scale gears used in the past are 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 held it in his hand and observed the gear. Sure enough, the weight, surface smoothness, hardness and other properties looked pretty good.

"Well, it looks like it is more than twice as good as the iron parts in the Sui Dynasty!"

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

Other craftsmen have successively used turbo rods, head beaters, new vises, iron clamps, chains, etc., all of which are made of the latest iron, and their performance is three or four times higher than before.

In the past, iron was brittle, so we could barely use it to build weapons, let alone make them into other mechanical equipment. When it is run, it is easier to break the frame. However, the quality of iron tools has been improved, and for simple hydraulic equipment, it can be assembled and manufactured.

Only with excellent parts can one set together and make equipment.

Luo Zhaoyun studied for four years in college. After all, he studied mechanical engineering for several years and still knew about this. Some sketches he hand-drawn, marked Arabic numerals, projection lines from various perspectives, etc., were a baptism for these craftsmen.

"The craftsmen work day and night, design and manufacture, and it's all hard."

"We serve the court, thanking His Majesty for his love for craftsmen, and with his salary, and he has raised his status. We are all grateful to His Majesty. This hard work is nothing."

These old craftsmen did have a strong sense of gratitude in their words.

"Craftsmen from great powers always need such people!" Luo Zhaoyun sighed softly and asked immediately: "How long does it take for the first hydraulic machine to be released?"

Zhou Jin replied respectfully: "The other parts are larger in size, require a larger amount of iron, and the casting and moving require a lever frame to cooperate, so the time will be delayed, and work day and night will take about a month to complete the initial assembly."

Luo Zhaoyun heard this and said happily: "Okay! I will visit the scene in one month to see it complete the debugging."

"Abide by the order." Zhou Jin and these masters respectfully praised him.

Luo Zhaoyun sighed: "Although the war is about to end, the national defense forces must not be ignored at all times. The divine arm bow, the shaman, the sky cannon, etc., still need to be manufactured. After the world is peaceful, the weapons must continue to be equipped to our soldiers and defend the frontier. Our Hua Dynasty wants to revitalize industrial manufacturing, not just a magic weapon created by a few masters, but to large-scale, standardized, mass production, and flow operations. Only when this is achieved can the industry be considered truly revitalized."

"Once this hydraulic forging machine is released, I think it is like the first hen raised at home, laying eggs through it, and then continuously hatching more chickens, and then repeatedly investing to finally reach the equipment batch, and all workpieces have unified standards. I hope that the masters can formulate a series of part error standards, sample and check, do a good job in data collection, and analyze the stability of mass production."

Zhou Jin and the great craftsmen were all in deep thought. Although they could not digest all the words of His Majesty for a while, and some words were still unfamiliar, but after all, they worked in this industry for a lifetime and understood six or seven points, and they all nodded and thought.

Luo Zhaoyun fully affirmed everyone's research, worked tirelessly and devoted himself to industrial research. These old men and middle-aged craftsmen are all Chinese people and scientific and technological personnel of the country.

It was already afternoon when I left the research base of the scientific research institute in the suburbs. Luo Zhaoyun was still very satisfied with the research results of the Institute of Engineering. After all, in the Sui Dynasty, he did not pay enough attention to industry. He introduced these concepts in advance, and with the first ray of dawn, I believe that the exhibition of China will still be helpful!
