The top blowing of the soil converter and the side blowing of the soil converter can be done at present, but if the side blowing is done, although the blowing effect is better, the operation is more difficult.

Yan Zheng didn't think about it, so he chose the converter top blowing method, which is distinguished by the position of the blowpipe air supply.

Side blowing is blowing on the side of the furnace, and top blowing is blowing from the top to blow the wind.

The principle and device are very simple, that is, the process of carbon removal is converted to rely on air blast.

In later generations, similar soil converters have been established in many places, and they don't even know the principle, as long as they follow the script, they can get it.

Historically, the development of converter steelmaking began to break out in the middle of the 19th century, and the reason is that the development of chemistry has made people's understanding of steelmaking reach a new height.

In the past, it was very blind to steelmaking, and when you know the specific principle of steelmaking, it is a targeted method to choose.

The converter is developed in this context, and the specific principle is that in the stage of molten iron heating, it mainly relies on the violent oxidation of silicon and manganese, as well as the oxidation of a small amount of carbon, to produce a large amount of heat, so that the temperature will gradually rise to 1450C.

Then the blowing enters the later stage, that is, the stage of decarburization into steel, and a large amount of oxygen is sent with the blast. The carbon in most molten iron will rob the oxygen in ferrous oxide and manganese oxide, absorb heat and form carbon monoxide, which then becomes carbon dioxide together with oxygen in the air, releasing a large amount of heat. At the same time, silicon continues to oxidize, and it also continues to release heat.

These two parts of heat will cause the temperature of the molten iron to continue to rise, so that a large amount of carbon will continue to be burned, and when the carbon content drops to a certain extent, the blowing will be over, and the molten iron will also become molten steel.

Compared to crucible steelmaking, blowing technology can save more fuel, can make more steel at a time, and can also reduce consumption a lot.

In the past, I chose crucible steelmaking because there was no suitable fuel for ironmaking, so no matter how good the technology was, it was not as stable as crucible.

Now that the energy problem has been solved, the explosion of steel production capacity is actually only a matter of time.

Yan Zheng pointed to the drawing and said to the ironwood needle: "According to this drawing, build a converter first, it's not a big problem, right?"

Tiemu Needle nodded: "These devices look strange, but in fact, we have already built them, the blower, the iron furnace, the earth converter, it is this blowpipe, it seems to be a bit of a problem, since it is to blow air in molten iron, is it this pipe, also iron?"

Yan Zheng smiled and said: "That's right, cast iron pipes are the best, and the parts other than the regenerator can be made of deerskin." It's just that when the blower is erected, it must ensure a constant speed, and this waterwheel can be built to a larger size, ensuring that it can drive three to four blowers! ”

The more he looked at it, the more satisfied he became, and his dark face showed a simple smile.

"If it were built to this size, then this stove would have to be three people tall, and a stove of this size would be amazing just to think about! If you build a dozen of them, I'm afraid that there will be so much steel that you can't use them up. Tiemu Needle sighed.

Yan Zheng continued: "Not only that, but this furnace is also connected to four iron furnaces, that is to say, after the iron is transformed, it is directly transferred to the blowing and refining, which is an integrated device." In fact, there is also a kind of side blowing, which is less difficult to build than this, but it is more difficult to operate, and the process of transferring molten iron is also prone to accidents. ”

"Then it's better to build this, just use it elsewhere!"

Yan Zheng snorted, looked at the reserved riverside and said: "Later, we will also get on the steam forging hammer, rolling mill, rolling mill, roll, vertical roll, coiler, straightening machine, and leveling machine." When the time comes, you will find out what the steel industry is really like! ”

Ironwood Needle thought about it for a moment, but his imagination could hardly think of that situation.

"Let's start preparing the square today, we need to write out the cooperation of those factories, now it's not as good as before, everything is standardized!" Yan Zheng said with a smile.

Tiemu immediately agreed: "I'll go and convene a meeting to discuss!" Guarantee to hand over the eucalyptus tomorrow and start work in a few days! ”

In Salt Harbor, a national flag flutters in the open space where the port and the quarantine area meet.

On the wall in the distance, lines of slogans are being written: Celebrate the founding of the Chinese Kingdom! Long live the Chinese nation! The Huaxia State is the only legitimate political power of the Chinese nation! Long live Yan Zheng, the monarch of the Chinese Kingdom......

There are many more such slogans, which are written all over almost every village, and as soon as the flag is hung, the slogan immediately follows.

When the people listen to the national anthem, look at the national flag, and then look at these slogans, they will subtly accept the imaginary community of Huaxia.

In time, this concept will be transformed into a national concept, and the so-called modern national concept will be established in the Chinese country.

The Ming descendants who came here to quarantine, in addition to purification, also had an additional process.

That is, every Monday, they must gather together to raise the flag and learn to sing the national anthem.

The daily flag-raising ceremony is also being carried out on the fleet of ships parked in the harbor.

The crew stood at the bow of the ship, singing "Singing Huaxia" while watching as the Star Spike Flag was slowly lifted in an oblique manner, until it reached the top of the mast, and was fixed by the sailors above.

Lehi looked at the star tassel flag fluttering in the wind, and slowly lowered the hand on his chest.

Soldiers need to salute when raising the flag, and others need to put their hands in fists in front of their chests when raising the flag.

Tian Wu was also standing aside, and the two had a rare meeting.

After the statehood, their fleet was thoroughly divided into norms.

With the launch of another Long March-class and quasi-barge, they now have one Long March-class and one barge-like barge, and two Fu-boats, respectively, and the 400-material Fu-boat was assigned to Tian Wu.

It seems that the power has increased, but in fact, all the captains are the original indigenous cadets.

"I'm going to sea! I'll go back to Zhejiang, do you want to make incense for your father and mother? Leaning in front of the railing, Li Haigou looked at Tian Wu and smiled.

Tian Wu shook his head: "Forget it, I didn't have the money to bury it at the beginning, so I found a piece of land at random, got a small dirt bag, and came here for two or three years, and I didn't know if the small dirt bag was there."

Li Haigou sighed deeply: "Then I'll go back to the village and burn a stick of incense, and burn some paper money, paper houses, and paper clothes."

Tian Wuqian looked at him and agreed: "You should burn it, and you should bury it, I'm afraid that some people are still rotting in the mud over there!"

Li Haigou nodded silently, and the original things came to his mind from time to time.

To say that the two have no hatred and no hatred, it is impossible, but Zhang He has already started business with this side, so they can only suppress their hatred.

"Then this time go and collect the Tanhu, you be careful!" Tian Wu reminded.

Li Haigou snorted, looked at the rippling sea and said, "This time it should be no problem, I will bring four boats over, and I have enough manpower!"

"You're alright!" Tian Wu smiled lightly and said: "If you go over there, you can at least find a few people you know, and I will go to Fujian, but it may not be!" People don't recognize us. ”

"Oh, it doesn't matter, do you remember that mother-in-law of the Song family?"

"The one you slept with?"

"That's right, she is from a family, you can go to the Song family and ask them to help, just take that mother-in-law with you by the way, it's not difficult!"

Tian Wu thought for a while and said: "But this time, the task is to say that the coastal state capitals must run, and in addition to collecting the population, they must also win over the local businessmen."

Li Haigou said: "This is also your advantage, there are so many coastal merchants in Fujian, you can just look for it." Unlike Zhejiang, except for Ningbo, I don't know what the situation is in other places! ”

Tian Wu nodded, and said, "The king is in such a hurry to gather the population, it seems that there is enough food here!" In the future, I am afraid that there will be more and more places for important people! ”

"This is natural, I heard my daughter say that in five years, this side will be very different, saying that the king has made a five-year plan, as long as one item is completed, it can make a big change here!"

"Five years!" Tian Wu thought back to what he looked like when he first came, and couldn't help but say, "What should Huaxia Kingdom be like at that time?"

As the horn sounded, he realized that it was time for him to return to the ship.

He hastily said goodbye, and returned to his ship, the Yangwei, through the planks built between the two ships.

This is a Long March-class ship with the number 17. It was launched half a month before the founding of the People's Republic of China, together with the No. 2 transport ship.

Now in the dockyard, two class barges are being built.
