Chapter Eighty-Eight: Shipbuilding Industry Symposium The emperor supports the naval army plan

The symposium on the development direction of the shipbuilding industry was very warm. At the beginning of the meeting, Zhang Zhimu asked Lu Wenchen to introduce the application of X-ray in the metal welding process.

Lu Wenchen was originally a little shy, but now Lu Wenchen is the principal of Yaogang Technical School and an authority on metal welding technology. Almost all the welders in the kiln are his apprentices, and their confidence is not ordinary. After a brief introduction, when it came to technical issues, Lu Wenchen found confidence.

"Not long ago, Mr. Zhang led us to see the miraculous ability of X-rays. X-rays can penetrate almost any object, with different densities and attenuation as they pass through the object. In this case, we can see images of objects of different densities after exposure with film. I won't talk about the benefits that the application of our welding technology has brought to us in metal processing. But this technique also has its weaknesses. That is, we can't guarantee that there is no problem with the metal weld, because the weld between the metals is not welded well, and sometimes, there is no way to see it completely clearly from the outside. This also limits the application of our welding technology. Even if it is used, many measures are taken to ensure reliability. And we use it on the boiler, and the pressure of the boiler does not dare to use too high. I am worried that the pressure is too high, once there is a weld defect, it will cause danger. Now that we have X-ray technology, we can take X-rays and take photos of all the key parts after welding. There is no problem with X-ray inspection, and we can use it with confidence. ”

As soon as Lu Wenchen's words fell, a boiler asked: "Is X-ray already usable now?" ”

"Yang Chang and they got us an X-ray machine a few years ago, and we are going to start the test soon!" Lu Wenchen replied.

"Shall we send someone to your experiment?" The boiler asked again.

"Of course!" After Lu Wenchen answered, he asked again, "What!" Not sure about us? ”

"Haha!" Lu Wenchen's question drew laughter.

"No, no, we want to master this technique as soon as possible."

Lin Qing spoke: "Principal Lu, you must hurry up on this matter!" With this technology, we can save a lot of time when building ships. Especially the keel, we are worried that there are bad welding, we also have to add reinforcing materials to the welding parts to avoid problems, and we also have to take a strengthening approach to the key parts of the hull. ”

The boiler said: "This technology is more important for our boilers, not only the safety problem can be solved, but we can also further increase the boiler pressure a lot." Especially after the application of our molybdenum steel, the pressure of the boiler can be increased even more. With the same boiler, the pressure increases, and the power and efficiency will also increase a lot! ”

"This technology is also very important to us, and we have very high requirements for welding quality. Besides, the pressure of their boilers has increased, and the efficiency of our steam turbines has also increased. ”

Lu Bingyi interjected: "It can be said that after the application of this technology, our shipbuilding industry can greatly improve the shipbuilding technology and shipbuilding quality." When we increase the pressure of our boilers, we can improve the efficiency of ships, trains and power plants. The same boiler and steam turbine power can be increased by a large margin. Principal Lu must hurry up on this matter! ”

Lu Wenchen said: "Mr. Lu, rest assured, this is a major matter that I personally grasped. ”

Zhang Zhimu said: "Things must be done quickly, but safety issues, don't be careless!" ”

"Okay!" Lu Wenchen nodded and said.

Lin Zongwei said: "Hearing such news makes people feel uplifted! ”

Zhang Zhimu said: "There are a few other things, for us shipbuilders, it is a matter of encouragement. Our echo detectors and radio detectors have been largely successful, and we are now in the process of designing the finished product. In addition, our radio navigation equipment has also been tested, and from this year, we are preparing to set up navigation base stations along the coast. In the future, radio stations, echo detectors, radio detectors, and radio guides will be necessary on our big ships. When we design the boat, we have to consider the installation of these equipment. ”

Zhang Zhimu's words caused another commotion, and Zhang Zhimu knew that many people didn't understand these things. He signaled Lu Bingyi to introduce it to everyone.

Lu Bingyi simply introduced the functions of these things to everyone, and everyone began to talk about it after listening. They were all shocked by the development of these technologies. They have a better idea of what these technologies mean.

Lu Bingyi said: "So! Our current charts are too simple. In the future, nautical charts will be marked in more detail above and below the water. So, I suggest that we should build a survey ship to measure all of our seas and make more detailed charts. ”

"I agree with Mr. Lu that we need such a ship. In the future, when we go to the ocean, we must first explore the road conditions in the ocean. However, I don't think the oceanographic survey should wait until the survey ship is built, and we should arrange for a ship to start the work immediately. Not only the oceans, but also our rivers and lakes must be measured. I suggest that this matter should be left to Shi Tao and them to do. Zhang Zhimu said.

Li Zongwei said: "Since Mr. Zhang asked to build such a boat, let's discuss with Shi Tao and them to see what kind of boat to build?" ”

"Mr. Lin is right!" Zhang Zhimu said, "However, I suggest that the oceanographic survey ship must have a large tonnage, so that it can work at sea for a long time and has much better stability." River survey ships can build small boats. ”

Li Zongwei said: "Good! Let's talk about this matter with Shi Tao and them. Shi Tao and they did not rest during the Spring Festival, and they have been taking people to investigate the coast. They need to determine the location of the security navigation base station as soon as possible. ”

Zhang Zhimu said: "We are now facing the problem of how to develop the shipbuilding industry and how to lay it out. I'd like to hear from everyone!

"I came back this time because I had some thoughts and wanted to talk to you. I think we should make good use of the Zheng Zhilong shipyard that we took over in Fujian, because it is in a good location and has easy access to wood around. In the future, as long as the boiler and steam turbine are transported, the wooden-hulled ship can continue to be built there. The conditions are not bad there, too! Li Zongwei said.

"I agree with Mr. Lin," Mr. Zhang said, "but I have a suggestion that we should rebuild a marine boiler factory and a steam turbine factory at the Zhenjiang shipbuilding base." Because our railway from Tongguan to Kaifeng can also be opened to traffic in two years, at that time, it will be much easier to transport steel. The boilers built there are not only for their own use, but also easy to transport to Fujian. Another thing is that we will also start the construction of our steel mill in Hankou, and in the future, it will be easier to transport steel from Hankou to Zhenjiang. Boilers and steam turbines from Zhenjiang can also be supplied to the shipyard in Hankou. ”

Lin Zongwei said: "It would be great if it could be configured like this! In this way, we will have four large-scale shipyards in Zhenjiang, Lingshui, Quanzhou, and Hankou in the future. ”

"Now the strongest technical force is still the Zhenjiang base." Zhang Zhimu said, "The 20,000-ton ship and the 1,500-ton steel-hulled ship of the Fuchuan system began sea trials last year. It was a breakthrough. Although the 20,000-ton ship is a wooden ship, I think if we can build a wooden-hulled ship with a steel keel, then we can also build a large ship with a steel hulle. Zhang Zhimu said.

"I'm here to study with Mr. Zhang, we are about to build two 1,800-ton steel-hulled ships of the Fuchuan standard, which are improved on the basis of those two steel-hulled ships. Because our motivation is enough. If our boiler pressure is re-improved, we will have more power. I would like to ask if we have enough steel, and if so, we want to build a 25,000-ton and a 5,000-ton steel-hulled ship, both as warships. Wooden boats built elsewhere were used as transport ships. Of course, this matter also needs Mr. Lu Bingyi and your people to participate in our design work. Li Zongwei said.

"Huh! You have a lot of appetite! This shows that you are very confident in yourself after the sea trial! Zhang Zhimu said.

"What Mr. Zhang said was," Lin Qing was not polite, "we just found the feeling after these ships were launched for sea trials!" ”

"As for the problem of steel, you can rest assured that you will use it, because you don't use so much steel at once." Zhang Zhimu said, "I agree with you, we need a few invincible steel-hulled ships. After we have dealt with the enemy on land, we have to deal with things at sea. However, we also have a very large demand for transport ships, and you should not stop building wooden ships like 5,000 tons and 20,000 tons, and those carpenters who build ships cannot weld steel-hulled ships. The scale that needs to be expanded to the shipbuilding base can be expanded as much as possible. ”

Lin Qing didn't wait for Li Zongwei to speak, and hurriedly said: "We came back this time to study the expansion of the shipbuilding base. Let's plan together with the construction of boiler factories and steam turbine plants! ”

Li Yunhe said: "The steel-hulled ships you built this time can use cannons of larger calibers. And now Yang Chang and Sun Liang are still working on the radio artillery system, and it is estimated that they will be able to use it when your big ship is finished. A dozen 304 caliber cannons on a ship, and a batch of 203 caliber and 103 caliber cannons, is simply a demon! Hehe! ”

"Oh my God! 304 caliber cannon, how much does the shell weigh and what is the charge? Lin Qing asked.

"The total weight of the shells is four hundred and fifty-five kilograms. The charge is one hundred and forty-three kilograms. Firing range nineteen km. It adopts a fully electric turret with electric reloading. Radio and optical sighting. ”

"One hundred and forty-three kilograms of charge?"

"Oh my God!"

“”

Everyone started talking in amazement.

After a while, Li Yunhe said: "You don't have to be surprised, Mr. Zhang said that we will develop larger calibers in the future, for example, we need 360 and 406 and 460 calibers." However, it needs to be used on board for a while, and then we will summarize the experience. ”

Someone asked: "How powerful is the 304 caliber cannon?" ”

Li Yunhe smiled and said, "It's best to ask Li Wei about this." He's been testing the gun! However, I can tell you that a building like our Yaogang office building can be solved with a single shell! ”

"You bastard, do you have such a metaphor?" Zhang Zhimu scolded Li Yunhe with a smile.

Hehe! After laughing for a while, Zhang Zhimu said: "In short, the weapons and other weapons supporting our ships have also made great progress. It has also laid very good conditions for our shipbuilding. However, there is a problem, and I would like to remind you that our ships all burn coal, and the amount of coal water used is very large. In the future, if you go to sea, you will have to be equipped with supply ships, because it is not easy for the ports along the way to replenish coal. However, I think there should be no problem in replenishing wood, so I suggest that in the future, your coal grinder should also have the ability to crush wood. There is really no coal, and blowing crushed wood powder into the hearth can also replace coal? ”

Lin Zongwei said: "Mr. Zhang's suggestion is very good, and this is also a problem that we will face in the future." ”

The boiler operator said: "It's not difficult, just adjust the air volume for burning coal and wood." ”

"Also, the desalination capacity needs to be strengthened. It is necessary to develop large-scale seawater desalination equipment. Our large ships are at sea for a long time, and they need to have enough fresh water for their crews. Zhang Zhimu said.

"Okay!" Lin Zongwei said, "This matter should be taken into account when we designed. ”

"I also have a suggestion that we should develop large passenger ships for sea voyages, and this kind of passenger ships should have good stability. It is best to add stabilizer fins on both sides of the boat. In this way, we can open passenger ships from Quanzhou or Zhenjiang to Guangzhou and Hainan, and even Luzon and Sulu. People can also travel long distances safely and comfortably! Zhang Zhimu said.

Li Zongwei said: "What Mr. Zhang said is also what we have always wanted to do. We agreed to develop a large passenger ship first. And it's going to happen soon. ”

Finally, Zhang Zhimu arranged two important research and development tasks. The first is to develop a large marine diesel engine, and the second is to develop a heavy oil boiler.

Large diesel engines occupy small space and have high power, which everyone knows, but large diesel engines are unimaginable. Everyone uses the marine diesel engine on the speedboat, and they know that it is good, but when it is used on a big ship, it is too big. Li Yunhe said: "The development of these things is likely to start with the development of large-scale processing equipment. ”

"This thing has to be broken through, no matter how much time it takes." Zhang Zhimu said with certainty, "There are also boilers that burn heavy oil must also be made." Because the calorific value of heavy oil is very high, burning heavy oil can reduce the space for loading coal, which is very meaningful for the ship. Moreover, in the future, our oil industry will further develop, and heavy oil will also be very abundant. ”

At that meeting, the specific persons responsible for these two matters were determined.

The meeting was very good. Not only Zhang Zhimu thinks so, but Lu Bingyi and Lin Zongwei also think so.

After the meeting was over, it was past noon, and Zhang Zhimu asked Yang Yulin to arrange lunch for everyone. Until the dinner table, everyone was still discussing today's events.

After the meal, Zhang Zhimu rested for a while and felt that he should go to Emperor Chongzhen. went to the phone to make sure that the emperor was in the hotel, and Zhang Zhimu came to the hotel.

Seeing the emperor, Zhang Zhimu said: "Your Majesty, there is good news to inform you today!" ”

"Huh! I knew that Zhang Dongjia would bring good news when he came! ”

"Oops! This is not good, if there is no good news in the future, I dare not come! Zhang Zhimu joked.

"Huh! There is no good news, you have to come, and you are good news for me when you come! ”

"Your Majesty, this morning, our navy has left Quanzhou and set off. Their first target was Jeju Island. Then take Tsushima Island! ”

Emperor Chongzhen listened to Zhang Zhimu's words, got up and came to the front of the large map, pointed to the location of Jeju Island on the map with a stick, and said, "Jeju Island should be taken back!" When the Yuan Dynasty was defeated, Taejo did not care about the islands overseas, and decades later, the Yuan officials there surrendered to the Koreans. Later, we negotiated with the North Koreans several times, but they were unwilling to return it to us, and we went back and forth, and this Jeju Island has always been in the hands of the North Koreans. You deserve to take it back. The people there must be looking forward to returning to us. ”

"With the emperor's words, it is even more time to take back Jeju Island."

"And yes! You still suffer from dividing the border with the North Koreans. Emperor Chongzhen said, "I have checked, the border between us and Korea during the Yuan Dynasty should be here, not the current border you drawn. Emperor Chongzhen pointed to the map (near Pyongan Province, North Korea) and said.

"Yes!" When Zhang Zhimu heard this, he felt dizzy in his heart, and said in his heart, I am really stupid, I finally got such an opportunity, and I still made it like this. "I'm really to blame for this. I thought that Tielingwei was the border! We still have to find a way to tell the North Koreans about the situation and see what they say. ”

"If they don't listen, they take it back. It's not like we can't beat them. We sent troops to deal with the Japanese on their behalf several times, but they didn't appreciate it at all. In turn, they also dealt with us with the Manchus, and if they didn't give them some color, they would be sorry! "Emperor Chongzhen's confidence seems to be much more than Zhang Zhimu's.

"What the emperor said is that if it doesn't work, they will all be destroyed." Zhang Zhimu said, "If we take Jeju Island, those people who have left North Korea will definitely send people to negotiate, and we just happened to tell them about it." But we need to complete the collection of materials, and when they come, they leave them speechless. ”

"No need, the Ministry of War has already sorted out the information, and when the time comes, you can just ask the Ministry of War!" Emperor Chongzhen said.

"That's better, let the military department negotiate with them, and when we need to do it, we'll do it."

Zhang Zhimu's words made Emperor Chongzhen laugh too, "Hehe! You, Zhang Dongjia, really have you! If you're right, let the military department negotiate with them, or you can go up again. Give the grown-ups something to do, too. ”

After Emperor Chongzhen and Zhang Zhimu returned to their seats and sat down, Emperor Chongzhen said: "I know a little about Tsushima Island you said, there are many mountains and few places, and there are not many people, and I let the Yuan army kill it once, and I almost killed it." ”

"We immediately want to emigrate from Fujian to there and to Jeju Island. Fujian has not experienced war in recent years, and its population density is very high. We can use incentives and support to mobilize people to migrate there, and we can help them establish themselves there. Zhang Zhimu said.

"Yes, yes! It's a good way, and with our people, it's ours. Emperor Chongzhen said.

"Unexpectedly, the plan to go north started from the sea to the east." Zhang Zhimu said with emotion.
