Zhu Youzhen did not stay in the Iron and Steel Smelting Bureau for a long time.

Iron and steel smelting is a basic industry, and it is difficult to make a major breakthrough in the basic industry in a short period of time.

This requires the emergence of new elements and substances, as well as the emergence of new alloying materials.

And all this requires the theoretical knowledge of Song Yingxing and other developers to be improved.

At present, the natural science theory system of the Ming Dynasty has not yet been fully popularized.

Anyone who has studied science knows that the most basic part of natural science is mathematics, then physics, chemistry, and finally biology.

This is the general classification of natural sciences in the modern world.

After hundreds of years of development, mathematics, physics and chemistry have almost built a complete basic theoretical system in the 21st century, which includes the contributions of many masters of mathematics and physics.

Newton, Galileo, Einstein, Bohr and Mendeleev must also be familiar to everyone.

In the 21st century, the mainstream of basic science is biology, because biology, especially in molecular biology and genetic inheritance, has a lot of room for development, followed by some fields of physics, such as electromagnetism, there is still a lot of room for breakthroughs.

However, in terms of basics, the basic theories in the field of mathematics, physics and chemistry have become quite mature in the 21st century after hundreds of years of development.

An undergraduate student can basically grasp these rules, of course, this refers to those who are serious about studying seriously, or are interested in science, and these basic rules are already known in high school.

For example, classical mechanics and classical electromagnetism as well as classical physics of statistical mechanics.

There are the well-known Newton's three laws, as well as the periodic law of chemistry, which summarizes the laws of chemical elements from the physical structure of microscopic matter, and the calculus of mathematics.

Zhu Youzhen is not a genius in mathematics, physics and chemistry, nor is he a great mathematician, physicist, or chemist.

He was just an ordinary college student in later generations, and his science knowledge was only that.

But in the Ming Dynasty and throughout the seventeenth century, his knowledge in the field of natural sciences was undoubtedly the most cutting-edge and erudite.

However, mastering oneself and passing it on to others are two different things, and the wrong use of a word in the laws of natural science may lead to theoretical laws that are thousands of miles away from the actual laws of nature.

Zhu Youzhen wanted to quickly pass on this knowledge to the people of this era.

But Rao is that he has always had good intelligence and memory, and he has not been able to pass on all the knowledge he has learned to Song Yingxing and others.

Now in addition to Zhu Youzhen, only Song Yingxing, Bi Maokang, Tang Ruowang and other people really have a physical and chemical foundation.

But their best level is only the level of the middle school in later generations, Song Yingxing is slightly better, and after being forcibly instilled by Zhu Youzhenmiao, he at least knows that the matter in this world is composed of elements, knows the difference between iron and carbon, knows how to refine ores with different combustion colors in the hope of obtaining new elements, and also knows the basic laws of mechanics.

However, fortunately, although these people do not have enough theoretical knowledge, they have a lot of experience.

The experience of experimental science is not inferior to Zhu Youzhen, and even much more powerful than Zhu Youzhen, a half-witted person who only knew how to write and read books and did not like to do experiments in college.

People can design experiments according to their own ideas, but Zhu Youzhen can't do this, and he has to rely on the guidance of university professors to design experiments.

Therefore, don't look at the fact that Song Yingxing and others do not have rich theoretical knowledge, there is still a big bottleneck for new technological breakthroughs, and there is no way to come up with rifled guns and smokeless gunpowder for a while.

However, the gunsmithing workshops and artillery manufacturing workshops and even gunpowder manufacturing workshops that people are building now have been quite large-scale and process-oriented.

The purpose of Zhu Youzhen's coming here is to have a basic understanding of the current military industry of the Ming Dynasty.

As the emperor, he can't build the industrial blueprint of the entire Ming Dynasty in every detail.

But in recent years, he has never underestimated this development, and a large part of the royal income has been invested in it.

Although it did not enter the steam age all at once, it was almost close to the stage of the steam industry age.

Moling is close to the Yangtze River and has a well-developed water system, and the water-powered firearms forging workshops are lined up on both sides of the stream.

Because it is under the square mountain, the potential energy generated by the water can be easily used to form power.

There is a canal between the gun forging workshop of the Gun Bureau and the Iron and Steel Smelting Bureau, and the iron transported by the canal is burned red and hammered through a hydraulic hammer, and then a special metal mold is used as the barrel mold, and the iron sheet is wrapped on the mold and forged into a barrel by the craftsman, and the barrel is extracted and cooled and then stored in the warehouse.

On the other side, the butt and firing device and steel knife manufacturing line also have their own assembly line for production, and then assembled by a unified assembly workshop.

In the whole process, the craftsmen are only responsible for their own process technology, and each process usually has a group of masters and their own apprentices in turn to be responsible for a certain process.

Most of the time, it is an apprentice operation that enters the training, and the master supervises and guides on the side.

Because of the appearance of His Majesty the Emperor Zhu Youzhen, these craftsmen and masters will personally get started, and the process will naturally be more skilled, so that Zhu Youzhen can see that at this speed, the manufacturing speed of flintlock pistols can be increased several times, and it is not easy to appear low-quality weapons, and it is not easy to leak technical information.

"The current Chongzhen 19-style flintlock pistol is using this hexagonal barrel, thanks to the emergence of the new iron fan, we have found that the barrel made of this iron fan can make the gun shoot farther and more accurate, and we are also experimenting with making a more complex iron fan as it must be suggested, before the barrel is formed, to create a threaded rifling, but at the moment this iron fan is a little difficult, because the iron fan is too hard, and it is too difficult to carve out the standard thread."

The iron fan in Song Yingxing's mouth is the meaning of the mold.

In ancient times, there were molds but they would be called "Fan", although Zhu Youzhen mentioned the mold many times, but because Song Yingxing and others still said "Fan", he could only follow the local customs, and then they also called the mold "Fan".

Zhu Youzhen only nodded when he heard Song Yingxing say this:

"The clay grinder I taught you can make cylinders, but can't you make such an iron fan, or you can use the grinding machine to cut out such thread rifling by boring instead of iron fan."

"Your Majesty's method is not impossible, although the grinder can cut jade and even cut out large gears, but the power is still not enough to boring this threaded barrel, basically a solid barrel without threads is also difficult to quickly boring out, because there is no such thing Your Majesty said that can be boring or milling or turning alloy steel knives, knives and bows we make now can achieve mass production, but Chongzhen series of muskets and field gun barrels are all new alloy steel cannons, harder, Without a good boring cutter, milling cutter or even turning tool, it cannot be manufactured, and the rifling is naturally not easy to draw, unless alloy steel is not used as the barrel material. ”

After listening to Song Yingxing's words, Zhu Youzhen somewhat understood what Song Yingxing meant.

The biggest obstacle to the production of rifled guns and more efficient guns is not only because of the lack of power, but also because the knives are not hard and sharp enough.

In terms of industrial farming, I would like to thank a few book friends in the book friend group for their help, and I will use it directly here
