Datang: Li Shimin begged me to rebel

Everyone subconsciously looked at Li Ke, a furnace of 5000 tons of iron, how much steel do you want Datang to refine in a year?what?At that time, houses will be built with iron, official roads will be repaired with iron, and carriages will also be made of iron, right?

Do you still want to build an iron kite to go to the sky?

The main reason is that Li Ke's planned goal is too outrageous. Everyone is just 20 tons of iron in a furnace, which is already unimaginable to them. If this efficiency is increased by 250 times...then the whole world will belong to Datang .

"So, does the ironworks have to be relocated to Chencang?" Li Shimin looked at Li Ke and asked.

"Yes, this is necessary, because in the future there must be a large number of supporting industries accompanying the steel plant, so this place is too close to the current Chang'an City, which is not convenient."

"It is very likely that the number of people around Chang'an will continue to increase in the future, which is one of the reasons why I asked people to relocate all the surrounding cemeteries."

"In the future, the city wall of Chang'an City may become a place to enjoy the scenery." Li Ke smiled.

Li Shimin rolled his eyes, what nonsense are you talking about?The city wall becomes a place to enjoy the scenery?Why don't you send someone to collect a fee?

"Is there anything else?" Li Shimin asked.

"Yes, let's go and see where the industrial mother machine is manufactured." Li Ke said with a smile.

"What is an industrial master machine?" Li Ke's mouth often came up with new things. As the minister of the Ministry of Industry, Duan Lun felt that he had to understand it immediately.

"Industrial machine is a machine that produces machines." Li Ke thought for a while and gave them a rough explanation. "I'll make an inappropriate analogy. For example, carpenters have tools such as saws, chisels, hammers, and planes."

"When we put these tools together on a machine, when the cut tree passes through this tool, it turns from a log into a formwork, and this machine combines all the functions of these tools."

"And if we call these tools machines, then the industrial master machine is the machine that produces this machine."

"This kind of machine is called a machine tool. It integrates different processes into the same assembly line, so that one machine has multiple processing capabilities and has high precision."

"The products they produce may be almost identical within a certain range. This is the charm of industrialization."

Li Ke's explanation was very clear, but everyone was still a little confused. It doesn't matter if they are confused. Li Ke took them directly to the machine tool factory.

The machine tool is a bit like a robot. In some science fiction, an intelligent program creates a robot, and then starts to manufacture robots through robots.

The machine tool is actually possible. You can build a machine tool for manufacturing machine tool parts, and then assemble it, which is a new machine tool.

Of course, Datang's current machine tool types are not many, mainly machine tools that produce various parts for steam engines.

With them, Li Ke soon arrived at the Datang No. [-] Machine Tool Manufacturing Factory, which was quite different from the previous steel factory. Several steam engines were produced to drive the machines, and workers were operating the machines beside them. After setting the relevant data on the scale, the steel molds began to be cut one by one.

Seeing the steel being cut into different shapes like ordinary wood, Li Shimin and the others were once again shocked by the charm of industry.

Before the Tang Dynasty, similar parts were either made of molds or hammered out by blacksmiths little by little.The former one is very accurate, but the parts made by the mold are likely to lose life due to unqualified steel quality.

Although it is said that before Datang, there were not many parts that required the use of high-strength steel.

But now, these are all directly processed by special steel, and the processing speed seems to them to be extremely fast, which is faster than some carpenters processing wood, right?Is this still the incomparably hard steel?

After each part is made, it will be continuously conveyed forward through a conveyor belt driven by a steam engine, and then on both sides of the conveyor belt, some workers will inspect these parts and pick out the unqualified parts inside.

In the end the parts were neatly put together.

Although it is incomparable with the assembly line operations controlled by the real CNC machine tools of later generations, the efficiency may be dozens or hundreds of times lower.But for the current Datang, this speed is already very terrifying.

These parts are finally shipped to an assembly plant, where individual workers assemble them.

"What is this machine made now?" Li Shimin looked at the machine and asked.

"Your Majesty, what I'm making now is a machine tool for the final grinding of the balls in the bearings." The director of the machine tool factory replied immediately.

"Ball?" Li Shimin was a little curious.

There are samples here, and soon someone showed Li Shimin a few balls. There are mainly two types, one is the most widely used cylindrical balls, and the other is spherical balls.

In fact, there are many types of ball bearings, such as deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, tapered roller bearings, self-aligning ball bearings, self-aligning roller bearings, thrust ball bearings, thrust cylindrical roller bearings , Needle bearings, etc.

At present, many of these bearings cannot be manufactured by Datang, and the precision of the manufactured ones is not so high, but the models are available.

In fact, these cast rollers are not as precise as later generations, and their lifespan is naturally incomparable with later generations, but having them is of great help to Datang.

There are not only rollers here, but also complete bearings.

Seeing the bearings stuffed with cylindrical rollers turning at a very high speed in the hands of the craftsman, all the ministers immediately thought of their updated carriages.

The wheels of these carriages are much smoother than the previous wooden wheels, obviously this is a special bearing.

"These bearings can be used in almost all aspects of industry. For example, some heavy objects can also use large rollers and bearings to rotate and move. For example, there are large bearings under the large molten steel furnace in the steel plant we have seen."

"In the future, these bearings may be used in any field we know, and this is just a trip of the industry." Li Ke introduced it to everyone with a smile.

After visiting the industrial mother machine factory, Li Ke took them to see the printing factory, paper mill and other factories.

Until the sun went down, Li Ke arranged another meal in the canteen of the last textile factory he visited.

Before eating, Li Ke secretly greeted Li Shimin, and Li Shimin naturally understood.
