When Yang Chong arrived at the Divine Blessing Zone, the heads of the various churches, under the leadership of the Director of the Department of Religion, greeted Yang Chong one by one. Pen % fun % Pavilion www.biquge.info

Look at the heads of each church, dressed in distinctive costumes. Yang Chongdu was a little dazzled.

If it were somewhere else, these church leaders were so amicably together that the sun was coming out in the west.

But Daming is a place of gods and wonders.

These churches, which have worldly feuds, can not only coexist peacefully, but also get along very well. Every believer has freedom of belief, and the Ming Dynasty will not interfere with it.

After all, there is a strict distinction between secular society and religious beliefs.

This is also the reason why the Ming Dynasty demarcated all religions together and strictly limited the scope of mission.

During the inspection, the responsible persons of each church gave Yang Chong a detailed introduction to the development of the church in Daming.

Subsequently, Yang Chong took all the church leaders to the Confucian church that the Ming Dynasty strongly supported. It is also known as the Temple of Confucius.

He also made an important speech on the actual situation of the inspection and gave some guiding opinions.

Of course, this is all prepared in advance. I say this now, but to show the wisdom and wisdom of the president.

Therefore, when it was publicized by the radio station, it became that President Yang Chong cared about the cause of the church and actively advocated civilized religious belief. And urge all churches to contribute their own strength to the cultural construction of Daming. In order to build a better Ming Dynasty, contribute to the bricks.

After this trip, Yang Chong was tired enough.

But he didn't have a day off before he was in full swing to arrange the next trip. Visit the Arsenal!

Truth be told, this inspection errand. It's really not like what you see on TV, the scenery is infinite.

That's tired! There is no place to talk about suffering!

Because the Ming Dynasty did not have a car like that of later generations, it relied on four-legged horses to travel.

Although the cement road is also very flat. But the carriage was still bumpy. Comfort is far from the car.

Now that Yang Chong is going out, what he is most afraid of is taking a carriage.

It's a pity that he has to sit in order to inspect!

According to the cabinet resolution, Yang Chong had to personally inspect it for a long time. The scope covers all walks of life. The reason is to motivate the enterprising spirit of all walks of life and drum up their motivation.

Among them, there are all kinds of factories in industry, and there are also bumper harvests in agriculture.

Basically, as long as it involves the development of the Ming Dynasty and the people's livelihood, he has to inspect it.

And he can't find someone who can replace him!

Like Cabinet Minister Nanfeng, his energy is concentrated on Nanyang. In order to eliminate and dissolve the newly acquired territory as soon as possible, he personally sat in Nanyang to deal with various political affairs such as immigration.

And the other ministers also have important matters to deal with at hand.

As a result, the entire Ming leadership could not find an idler.

In this reluctant situation, Yang Chong came to the arsenal again.

In fact, this inspection is a face-to-face project.

If you really want to see the reason, then you can only ask Sun Wu Kong. After all, Yang Chong is just an ordinary person, and he doesn't have the ability to be sharp-eyed.

And he doesn't understand a lot of things.

When he arrived at the arsenal, he was just putting on a show, saying some provocative and inspirational polite words. Then I will take out the prepared manuscript and give a speech.

The whole process is over.

However, the arsenal is related to the country, defense and security of the Ming Dynasty, and even if Yang Chong feels that there is no more to talk about, he has to pretend to be serious and cautious.

So he was patient and listened to Mu Chun's explanation of the development of the arsenal.

The first is the bullets.

Although Daming has been able to produce bullets, the quality of the so, I really dare not compliment.

It is important to know that bullets are divided into four parts: charge and barrel, bottom and fire, fire and shot, and bullet and head. No matter what kind of bullet it is, it is made up of these four parts.

And no matter what the use, most of the common ones are smokeless gunpowder. Among them, it is divided into single base, double base, and three base.

Nowadays, firearms mostly use single-base drugs.

Let's talk about the primer: the components are the fire transfer hole, the fire anvil, and the strike.

The effect is to generate a flame when fired, and ignite the fire, shot, and medicine in the shortest possible time.

When fired, the firing pin activates the fire cap (primer), which in turn quickly ignites the ****** inside the cartridge (cartridge case), causing it to ignite instantaneously. At the same time, high temperature and high pressure are generated to extrude the projectile head from the shell.

At this time, the head of the projectile moves forward under the propulsion of high pressure. It is squeezed by the rifling, which spins and is finally ejected from the chamber.

The cartridge case is the most critical component in the production of bullets.

It is used to hold hair, fire, and medicine, and to connect the warhead to the primer. When fired, it also has to withstand the pressure of gunpowder gases and the force of the firearm automaton.

What Daming can learn from is the domestic Type 56 ordinary bullet. The shells used are divided into composite copper steel and deep-drawn high-quality carbon steel.

Compared with the two, the production process of copper steel is simpler. But it is relatively expensive, and the utilization rate of the plates is also low. Not only does copper be consumed, but it is also difficult to recycle.

The production process of deep-drawn high-quality carbon steel is more complex, and the requirements for molds and machine tools are higher. But there is no need for copper, and the material is also very cheap. And it can be reused, and the economy is good.

The predecessor of this steel is carbon steel. It is an iron-carbon alloy with a carbon content of less than 2% and a small amount of silicon, manganese, phosphorus, sulfur and other impurities. It is widely used in construction, bridges, railways, vehicles, ships and other industrial, transportation and infrastructure construction.

Its performance is mainly determined by the carbon content. When applied to industry, the carbon content generally does not exceed 1.4%. Because after the carbon content exceeds this standard, the steel will exhibit great hardness and brittleness. It causes processing difficulties and loses production and use value.

When the carbon content is less than 1.35%, it does not contain other alloying elements except for iron, carbon and impurities such as silicon, manganese, phosphorus, sulfur and so on within the limit.

Such an important steel has always been the object of the Ming Dynasty.

Since the industrial bubble, Daming has increased its investment in steel research.

Although there are not many related professionals in Daming. But on the high-speed rail plane, you can still find a few.

Wasn't Mu Chun, Minister of Industry, the boss of the steel mill before?

And he climbed up from the bottom step by step, and is most familiar with all aspects of steel manufacturing.

After the industrial equipment in the UK was in place, he led the relevant personnel and studied hard. It took hundreds of days and nights to finally make a major breakthrough in steel quality.

Then, because of the need for bullets, we specially conquered deep-punched high-quality carbon steel.

Compared with ordinary carbon steel, the content of sulfur, phosphorus and other non-metallic inclusions of deep-drawn high-quality carbon steel is lower, the carbon content is greater than 0.6%, and the manganese content is between 0.7~1.0% and 0.9~1.2%.

Mengneng improves the hardenability of steel, strengthens ferrite, and improves the yield strength, tensile strength and wear resistance of steel.

Bullets running at high speeds happen to need such steel to make cartridge cases.

In order to overcome this technical difficulty, Mu Chun and the others spent a full year. The affairs of the cabinet were all lost to Yang Chong and others.

Now it seems that this sacrifice is worth it!

After all, it's good, the gun is good, and the bullets are good!

Like the previous excellent rifle with 38 resistance, operation and wear, the bullets are too inferior, which makes the rifle damage rate extremely high.

This is placed on the battlefield, and it is the Ming soldiers who are injured.
