Chapter 362 Lasting Guarantee: Refractory Bricks
Chhetri and Kidambi both felt a chill. They did not expect that the situation here would be like this: there was no suitable dock, and they had to use the crudest method to repair it!
You can guarantee the quality of it?
They began to murmur in their hearts.
"Please believe in the capabilities of our Red Star Shipyard. We will definitely be able to refit that aircraft carrier. We are ordering the relevant materials. Once the aircraft carrier washes ashore, we can officially start repairs."
"Yes, our capabilities are much stronger than yours." Nicholas said from the side.
Of course he could see the dissatisfaction in the hearts of these people, but these people had no other choice. Do they still want to drive back to Asan Country for repairs? Of course that won't work, they just want to make money for repairs.
Nikolai and Kvyat sang in harmony, so Chhetri and Kidambi, who came to accuse them, could only leave in anger.
After the two left, Qin Tao took Xu Zhengyang and followed Zaitsev before coming out again.
“It’s a really nice place there.” Qin Tao said with a smile: “Director Kvyat, I guess you must have a few beautiful female secretaries.”
Kvyat's old face turned red: "Mr. Qin, you are really good at joking. I don't do that kind of thing."
“Then you often drink there?”
For Lao Maozi, he may like wine more than communicating with women about his life.
Now Kvyat nodded: "Yes, that was before. In recent years, I have not been in the mood to drink at all. Ah San was too anxious, Qin, please fulfill our agreement as soon as possible. "
"No problem." Qin Tao nodded: "I will arrange these things when I get back. Nicholas, my friend, I still have some things I want to talk to you about."
Kvyat left wisely. Nikolay looked at his old friend with a smile: "Qin, what else do you have in mind?"
“I may also need a batch of Yak-38 and AL-21 engines.” Qin Tao said: “There should be another batch from the Northern Fleet. Can you contact me?”
Since it’s here, let’s mention it.
"Of course it's no problem." Nikolai nodded: "They were very envious when they saw that we sold the Yak-38. They only have one Baku at the moment and don't need much, so they bought half of it from over there. It’s no problem to come back, I’ll call you now and ask.”
Nikolai called on the spot, but when he heard the news from over there, his expression changed: "What, your Baku's boiler exploded? Oh, you are really unlucky. Last year there was a fire, this year The boiler exploded again, it looks like it needs to be repaired.”
Hearing Nicholas's words, Qin Tao also smiled secretly in his heart.
Different from the previous warships, the Baku is the latest heavy-duty aircraft-carrying cruiser that was put into service in 1987. It is only six or seven years old now. For a warship, it is in the best golden age. age period.
Therefore, the Mao Navy has always wanted to use the Baku as its main warship. After all, the Kuznetsov is not yet equipped with carrier-based aircraft and has no combat capabilities.
It's a pity that due to bad luck and ill-fated fate, this warship also has quite a lot of problems. Since it was put into service, it has not had much peace of mind. It has also experienced frequent breakdowns in the past two years. There was a fire last year, but fortunately nothing serious happened. Fires are common for aircraft carriers. What about this year? This year is a blast!
A boiler explosion is definitely a major accident for a warship, and the Baku was even more miserable this time. It is said that the high-temperature steam steamed dozens of poor sailors on the spot.
"Nicholas, we can't let them know that we can provide boilers. For us, even if we make less money, we can't let the news leak out." Qin Tao reminded.
Nicola nodded.
The Baku's boiler exploded, and repairs will definitely be needed next, and the boiler must be replaced.
This will be a huge expense, because the boiler factory in St. Petersburg simply does not have the ability to continue producing boilers, and huge sums of money will be invested in production.
On the other hand, Qin Tao can provide brand new boilers.
However, it cannot be said that Ah San would definitely be unhappy if it reached Ah San’s ears.
For the Pacific Fleet, it must prioritize its own interests.
Qin Tao’s reminder was entirely for Nicholas’s benefit.
Of course, Nicholas didn’t know that Qin Tao had a lot of tricks up his sleeve.
Since the Baku is broken, it must not be repaired. If it is repaired, Damao will not sell this warship.
Of course, there are many problems in repairing Damao. For example, funding is a big problem. However, Qin Tao will never be a helper, he will have to sit on the sidelines.
Qin Tao only stayed at Lao Maozi for one day. The next day, he took a passenger plane and flew directly to Huating.
When Qin Tao came back, the An-225 transport plane also flew back and towed all the equipment at the defense exhibition back again.
Qin Tao did not go to the airport to greet him, he had to arrange the next thing.
The Second Design Institute of Mingzhou Shipbuilding Industry Group.
"Why, you have already started the design?" When Qin Tao came to inspect this place, he was surprised to find that the design drawings of his 28,000-ton aircraft carrier promised to the Turkey Country had already started on the computer here. Drawn.
He came here, on the one hand, for the boiler, and on the other hand, to assign tasks to the big guys, but he didn’t expect that the big guys would move so fast!
"Yes, after you discussed the project with Tuji Country the day before yesterday, we got the news that this design task must be completed by us, so we started to carry out the preliminary design. We guarantee that within three Within a month, the design drawings can be completed," Babic said.
"Within three months? What are you doing so quickly?" Qin Tao glanced at Babbage: "Old Mao, this design drawing has a one-year design period."
What, one year? Babbage was a little surprised: "Why did it take so long?"
Since their design office was established, they have been constantly designing various aircraft carriers. They have rich experience and computer design has also brought great advantages. They only need to modify some of the original design drawings. , three months is no problem at all.
“This is the first time we have taken out a design drawing. We must be careful and patient, and we can’t make any mistakes.”
“Mr. Qin, this is not the first time, we have sold before.” A designer whispered.
Qin Tao rolled his eyes at him: "If you talk too much, this month's bonus will be gone."
The designer shut up immediately.
Qin Tao reprimanded the disobedient children and continued chatting with Babbage: "Is there any problem in the design of this aircraft carrier?"
“There is no big problem, but the displacement is still a bit small, which is not good for the operation of the aircraft carrier. If it can be enlarged to 40,000 to 50,000 tons, the combat effectiveness will definitely be able to reach a higher level.”
“In that case, the cost will soar. Although we only focus on design, we also need to save money for users. By the way, we need to design the aircraft carrier deck to be thinner.”
Thinner?
Babic was a little surprised: "Why?"
“This can lower the center of gravity.”
For an aircraft carrier, the most important design is the deck, but the deck is definitely not the thickest, because in that case, the center of gravity will be too high and it will easily tip over.
The deck needs to have the strongest impact resistance, but the deck is not the thickest, so the deck needs to have the highest strength.
In this way, even if the Turkish Country has the drawings, it will not be able to produce it. Maybe it will still beg the Mingzhou Group to continue to sell them high-strength steel in the future?
Of course Qin Tao can't express this reason now.
"Okay, we listen to you." Although Qin Tao didn't say anything about deducting Babbage's bonus, he had to listen to Qin Tao.
“By the way, how is the power system?” Qin Tao continued to ask.
“The power system is based on the technical parameters of the new boiler we have designed so far. Only four boilers are needed to drive two turbines to allow the aircraft carrier to reach a speed of thirty knots.”
The Kiev-class aircraft carrier uses eight boilers and drives four steam turbines, reaching a speed of more than 30 knots. However, the Kiev-class aircraft carrier is an aircraft carrier with a displacement of more than 40,000 tons after all. By the time of the Baku, it even reached 45,000 tons.
The model they are currently designing has a full-load displacement of only 28,000 tons, and the boiler they designed has higher parameters, so half the power is enough. After all, even if these boilers are needed to propel a 60,000 to 70,000-ton aircraft carrier, only eight of them are needed.
“Brand new boiler parameters?” Qin Tao asked curiously.
This time it was Wang Yanwei's turn to speak.
"Mr. Qin, we have made a lot of improvements after dismantling the original TB-12 boiler." Wang Yanwei said: "Our newly designed boiler can output 120 tons of high-pressure steam per hour. More than the prototype Five tons.”
The boilers used by aircraft carriers can produce more than one hundred tons of steam per hour. Now, our own boilers can be regarded as reaching a new height.
“What about security?”
What Qin Tao is most concerned about is safety. After all, the **** fact that Lao Maozi's aircraft carriers often explode boilers is right in front of him!
Their boilers cannot be like this.
Refractory bricks!
Qin Tao also became serious. He had promised Lao Maozi to provide a batch of refractory bricks.
For boilers, refractory bricks are essential.
The boiler is divided into two parts: "pot" and "furnace". (It must be said that our Chinese culture is broad and profound) "pot" is used to boil water, and "furnace" is the place where fuel is burned. It consists of combustion equipment, combustion chamber, furnace and Flue composition.
Whether the boiler is working properly, refractory bricks are crucial.
The internal temperature of an ordinary civilian boiler is around 1,500 degrees Celsius, while the internal temperature of a heavy oil boiler used on warships is as high as 1,800 degrees Celsius. Such a high temperature poses a serious challenge to the thermal insulation materials.
Refractory bricks are built in the furnace walls of the combustion chamber and flue. After passing through the refractory bricks, the temperature must be reduced to 300 degrees Celsius to be considered normal.
Moreover, this is different from the boiler on land. This is on a warship. It not only has to withstand the internal heat wave, but also withstands the operation of the warship, such as artillery firing, missile launch and strong wind and wave navigation. Strong vibration and shock. For aircraft carriers, there are also collisions of carrier-based aircraft and so on.
If the refractory bricks in the boiler collapse under a violent impact, the consequences can be imagined.
“Do we have better refractory bricks?”
"Yes, Professor Yang from our college has successfully developed composite refractory bricks based on new ceramic materials. This material has won the first prize of our navy." Wang Yanwei said: "We are based on this Only with this material can we have the confidence to increase the steam capacity to 120 tons on a boiler of the same size.”
Wang Yanwei was very excited when he talked about this.
The previous Type 051 destroyer used boilers. The technology introduced from Lao Maozi at that time used aluminum silicate refractory fiber materials. The performance of this material was not good. The refractory temperature was limited, and the fibers were prone to powdering, peeling, and moisture absorption. It absorbs moisture and has a short working life, so every few years, refractory bricks need to be replaced, otherwise accidents may occur.
Professor Yang Chun has been researching in this direction for many years and finally developed this new material, successfully solving a big problem.
“Professor Yang has done a great job. It is equivalent to developing a brand new protective goggle for the heart of our warship.” Qin Tao said.
“That’s right!” Wang Yanwei was very excited.
“In this way, all the technical problems will be solved.” Qin Tao said: “We don’t need to take care of the avionics equipment above. The customers must have purchased various equipment from the West. We only care about the hull.”
Babic nodded there, so we said three months would be fine, but you actually want us to spend a year!
Looking at the dissatisfied Babbage, Qin Tao smiled: "Old Mao, this design is just for practice. All the 20 million design fees will be given to the design office. In the remaining time, you can do whatever you want. .”
Qin Tao has great trust in Babbage and is very capable of delegating power. Here, Babic, a foreigner, is the leader and speaks the truth.
The design fee of 20 million US dollars will all be transferred to the account of the design office, and whatever he wants to do is up to him.
“I heard that Krasnopolski is here too?” Babic asked Qin Tao.
The project on deep-diving lifeboats is public, so when these people come to the East, the news has already spread.
Hearing Babic's question, Qin Tao nodded: "Yes, why, are you interested in meeting him?"
“Yeah, I want to ask him to help design a nuclear reactor for aircraft carriers. Since you gave us the design fee, it must be put to use.”
Qin Tao smiled.
For Lao Maozi’s aircraft carrier designers, nuclear-powered aircraft carriers were also their dream, and they were about to come true. However, with the collapse of the Red Empire, everything came to an abrupt end.
The Varyag is at least still a shell, and the nuclear-powered aircraft carrier has been dismantled to pieces.
The unfulfilled dream of the Red Empire can only be realized in the East. Even if there is no plan to build an aircraft carrier in the East, it can still be done on paper.
“If you want to design a nuclear reactor for an aircraft carrier, then Krasnopolski alone is not enough, you need at least a team of fifty people.” Qin Tao said.
Even with computer-aided design, a nuclear reactor cannot be designed by one person. The news that a college student from a certain country designed a nuclear reactor in his own garage is just a boast by the ignorant media.
"That's true." Babbage frowned.
He just wants to have funds and draw up a design, but the problem of manpower is not something he can solve.
"In this way, the contact with Krasnopolsky is up to you. As long as you can fool him...please come over and I will take care of the other helpers. But you have to make sure that as long as he participates in this project, in the future I will stay down-to-earth.”
Babic nodded: "I am very familiar with him. He is an ideal person. As long as his ideals can be realized here, he will definitely choose to stay."
“I can promise that the ideal of nuclear-powered aircraft carriers will definitely be realized.”
For an aircraft carrier, the most suitable power source is of course a nuclear reactor. It can be refueled once and the nuclear raw materials can be replaced at most once during the entire life cycle. Even the latest nuclear reactors can have the same lifespan as the aircraft carrier.
In this way, a large amount of space on a nuclear-powered aircraft carrier can be used to store aviation fuel and ammunition, and even fresh water does not need to be stored. The excess electricity produced by the nuclear reactor can be used to desalinate seawater.
Inviting Krasnopolski here, it was originally intended to design a nuclear submarine reactor. Now, it must first play a role in a nuclear-powered aircraft carrier.
Of course, Krasnopolski can't do it alone. Qin Tao will invite a large number of domestic nuclear reactor designers to join in. In this way, they can learn from each other's strengths and design together, and maybe they can actually make a perfect design. Woolen cloth.
Of course, this road will be long, maybe ten or twenty years, but Qin Tao believes that this day will eventually come.
Now, just move forward step by step and down-to-earth.
Qin Tao’s feet once again stepped on the ground of Huating Naval Academy.
“In front is the Department of Steam and Gas Power Engineering. Professor Yang is currently the deputy director of this department.” Wang Yanwei pointed to a small building in front and said.
“Well, if we come here rashly, I don’t know if we will disturb Professor Yang.” Qin Tao said.
“Of course not. I have called you in advance. Professor Yang is very happy to know that you are coming.”
Finally, the two entered the small building.
After many years, the walls of the small building have begun to be mottled, but they are still neat. In the laboratory on the first floor, Qin Tao saw Professor Yang with white hair.
“Mr. Qin, welcome. I never thought I would have the chance to see you.”
“Professor Yang, what you said makes me ashamed.” Qin Tao held the other person’s hand: “I’m just an ordinary person.”
“Ordinary people? Ordinary people don’t have as much ability as you. By the way, are you interested in my research project?”
"Yes, Professor Yang, the refractory brick material looks inconspicuous, but in fact it is of great importance. I learned that you have a new refractory brick that can significantly improve the performance of our boiler, so I came here to visit. Professor Yang, you He has done a great service for us!”
Professor Yang pushed up his glasses: "Mr. Qin, it's rare that you are interested in the project I have developed. To be honest, my project has only been successfully developed now, and I am actually very uneasy. After all, our warships have already started to use gas turbines. . At the boiler factory, there are no orders for even one boiler for warships. I’m still worried whether it will be eliminated in the future.”
At present, among the new generation of domestically produced warships, frigates use four diesel engines to combine firewood and diesel, while destroyers use gas turbines and diesel engines to alternate firewood and firewood. In this way, boilers are useless. By the way, the refractory bricks of the boiler are in an embarrassing situation.
After spending decades of hard work and achieving significant results in this field, only to find that his research results are no longer useful, this gap is unacceptable.
"Of course not." Qin Tao said: "On 10,000-ton warships, heavy oil boilers are indeed outdated, but on warships with larger displacements, boilers are still the most suitable choice. Professor Yang, your research project It’s very important. Now, the aircraft carrier we design for Turkey is expected to use this kind of refractory bricks, and we also have export orders for three boilers, which will also use this kind of refractory bricks.”
“Really? We still have export orders for boilers?”
Even Wang Yanwei was surprised now.
Qin Tao nodded: "Yes, now that we have developed it, we need to convert it into productivity. However, there is no need to install the boiler alarm system. Next, you will be responsible for contacting our boiler factory. Produced in accordance with the design drawings, the relevant accounts will be handled by Mingzhou Group."
"Yeah." Wang Yanwei nodded. Although he didn't know why Qin Tao asked to remove the boiler's alarm system, he just followed Qin Tao's request and there was no need to ask any more questions.
“By the way, what did our old refractory bricks look like?”
Qin Tao looked at the laboratory with curious eyes, so Yang Chun picked up another piece.
From the appearance, the two refractory bricks have similar colors and are similar to compressed biscuits, but they are much larger.
“We will also produce a batch of this original refractory brick according to the shape of this boiler, and we will export it.”
“Well, I’ll get in touch.” Wang Yanwei nodded.
But later, Qin Tao thought of something and shook his head: "No, the quality of our original refractory bricks is still too good. Let's contact a civilian refractory brick factory to produce refractory bricks of corresponding shapes!"
"Civilian use?" Wang Yanwei was a little confused now: "Mr. Qin, the civilian refractory bricks are used in land boilers and cannot withstand the use environment of our warships."
“I didn’t say it would be used on warships,” Qin Tao replied.
If you are not on a warship, why should it fit the shape of a warship boiler?
Wang Yanwei was full of doubts, but he still didn't ask.
Since Mr. Qin has arranged it like this, it must have deep meaning. No need to ask, I probably won’t understand it myself.
Only Xu Zhengyang was smiling there.
