Chapter 338 Disassembled K534

Chapter 338 The dismantled K-534

"Of course not." Qin Tao was very direct: "We have never thought about making that thing at all. Except for the wealthy Red Empire, it is impossible for any country to use precious titanium alloy to build nuclear submarines. It is too luxurious."

There are only four Type 945 nuclear submarines, and the fifth one was stopped in the early stages of construction. This does not mean that Moscow looks down on the red Solmovo Shipyard. Another main reason is that titanium alloy submarines are too difficult to build. .

During the welding process of the first Type 945 nuclear submarine, it was found that the quality of the welds was very low and cracks existed in many places. Later, it had to be reworked, and it was only by the time of the second ship that the quality was stabilized.

Qin Tao spent three million US dollars to purchase this welding technology from the Celestite Design Bureau. It was absolutely worth it.

Although the production is in the shipyard, technical things are all controlled by the design bureau. At the beginning, the Celestite Design Bureau had a headache for a long time because of the welding problem of titanium alloy.

At the beginning, they planned to use treated T-17 zirconium-containing titanium alloy. However, due to the problem of welding cracking, they specially ordered a new 48-inch alloy from the "Prometheus" Central Shipbuilding Technology Research Institute. - ОТЗВ type low zirconium titanium alloy. These were all solved by the Celestite Design Bureau.

Now, it’s not that they can’t be given. Twenty Lavkovsky felt that Qin Tao’s request was a bit strange. According to their engineering experience, this thing is used to build submarines!

Now, what does Qin Tao plan to use it for?

"If our transaction goes well, I want to use these materials to build advanced deep-diving lifeboats to fill our gaps." Qin Tao said, "Of course, since we have very little experience, I would like to ask you to Some experts from the design bureau went to our place to help with the design.”

If these titanium alloys are taken back and sold as junk, these people will never believe it. If they are talking about titanium alloy components for making airplanes, then they will definitely think that the price is cheap. After all, airplanes are very expensive, so Qin Tao simply Talked about a new idea.

Deep diving lifeboat.

Just by listening to the name, you can know its function. This kind of small boat can dive to deeper places and carry out rescue work.

Rescue who?

Of course it was the submarine in distress.

A normal submarine is a powerful weapon on the bottom of the sea. However, once a malfunction occurs and it cannot surface, it will be difficult. Especially if there is a water leak or the like, it will face a crisis.

At this time, this kind of specialized deep-diving lifeboat is needed.

Compared with ordinary submarines that can only dive to a depth of two to three hundred meters, its diving depth must be at least 600 meters or even less than a thousand meters. The deeper the better, so that it can cope with more situations. more.

This kind of lifeboat does not need to have strong maneuverability or high speed, but it must be able to make complex posture adjustments, because a submarine in distress can sit on the bottom of the sea in various postures, and the upright one is best, but if If it's tilted, you have to tilt it too.

Because it has to be docked with the hatch of the submarine, the crew members in distress can climb directly to the lifeboat through the docking port. At that depth, personnel cannot be directly exposed to the outside.

Any country with submarines should have deep-diving lifeboats, but such things are too difficult, so only a few countries can build them.

Even domestic submarines that have been in operation for decades only started construction of the first deep-diving lifeboat in 1988, with a diving depth of only 600 meters.

Before it was put into service, once something happened to previous submarines, they had to find ways to save themselves.

Now that Qin Tao has made this request, it is reasonable and reasonable.

The designed depth of the Type 945 nuclear submarine is 900 meters, but in fact, this submarine can dive to 1,200 meters without any problem. After all, it uses the strongest and thickest titanium alloy. (There is also some information saying that the diving depth is 600 meters. I don’t know which one is true.)

At the same time, the displacement of the Type 945 nuclear submarine is more than 8,000 tons, while the displacement of the deep-diving lifeboat is only a few dozen tons. This lifeboat has a smaller diameter and can be made into the most pressure-resistant spherical shape. Therefore, if the same materials as the 945 nuclear submarine are used, In terms of technology and craftsmanship, then this kind of deep-diving lifeboat can dive to a depth of two thousand meters without any problem!

Ravkovsky nodded, but he still thought of something and said seriously: "In this case, wouldn't it be more cost-effective for us to design it in the design bureau, build it in the shipyard, and then sell it to you? Such a deep-diving lifeboat can be sold for at least 20 million dollars, right?”

Lapilov is a little embarrassed, brother, can you say this directly?

"No, no, no." Qin Tao shook his head repeatedly. He pointed at Lavkovsky and then at Lapilov: "You, you, even if you work together, you can't build this thing, because You have no money!"

Qin Tao revealed the secret with one word. It was impossible for the other party to do this, because both design and construction required money, and their child, whose father did not love his mother, was even more so now. Abandoned, where is the money? What to do if you have no money?

In fact, since Lavkovsky could say it face to face, he actually already had the answer in his heart. Now, he is not angry when Qin Tao points it out directly.

"Yes, we have no money. In the past, we never thought about money."

For these third-tier shipbuilders, the feeling is even deeper. They miss the lost empire very much.

"So, it is best for you to choose to cooperate with us." Qin Tao said: "Going to our Dongfang, those designers can get high salaries and live a comfortable life. By the way, if our project is negotiated, I also hope that the shipyard can send some skilled technical workers over. If the relevant equipment is lent to us for use, it will be even better. We will pay."

Xu Zhengyang's heart is as clear as a mirror. President Qin has started to dig people and equipment again. This time he is bolder and comes directly!

Those designers and technical workers are definitely meat buns hitting dogs, and they will never come back.

As long as those people go to the East, they will definitely like the East and don't want to come back.

Although they use the guise of deep-diving lifeboats, these designers are actually designing submarines. In other words, after they decide to stay, Mingzhou Shipbuilding Industry Group can set up a third design department to design submarines!

Thinking of this, Xu Zhengyang was excited.

What he thought was right, but there were only some minor modifications. If a special submarine design department was to be established in the future, it would probably belong to the navy. After all, such an institution could not be privately owned. However, those were things to come later.

Now, let's fool these people and equipment first.

Under Qin Tao's gaze, Lavkovsky finally nodded: "If you send those designers out in the name of our design bureau, in addition to paying the designers' salaries and travel allowances, you also need to pay a fee to our design bureau."

This guy also knows how to get more benefits for their design bureau. In fact, most of these expenses have to go into his pocket, right?

"Of course no problem." Qin Tao nodded immediately: "Everyone, every month, give your design bureau one hundred dollars. The more people and the longer the time, the more your design bureau will get. The same is true for the shipyard. How do you feel?"

"Okay!" Both of them nodded and agreed without hesitation.

"Tomorrow, I will take you to the production workshop of the Type 945 nuclear submarine." Caipilov said.

The agreement was reached. Sure enough, without Grishin's trouble, the gains would be greater!

After the banquet, everyone returned to the guesthouse. On the way, Zheng Ming smiled and said to Qin Tao: "Boss Qin, this time the gains are good!"

"Well, good luck, tomorrow, you can also go and see it together."

"Boss Qin, it seems that our navy's new generation of nuclear submarines will also rely on you." Deng Rui, a submarine expert who followed Zheng Ming, said.

"Mr. Deng, please don't add pressure to us. Let's talk about the future later."

"Boss Qin, I'm a little confused."

Xu Zhengyang's words became more and more. Qin Tao glanced at his secretary: "Do you think there is a problem with my payment method?"

Xu Zhengyang nodded.

He could guess everything else, but Qin Tao's way of paying the design bureau and shipbuilding personnel made Xu Zhengyang confused.

"Do you know how the Red Empire reformed its factories after it collapsed?"

"Isn't it just one ticket per person? It became waste paper in the end."

"Of course not that." Qin Tao said, "It's their personnel system. Forget it, let me tell you. They also began to learn from the West and adopt a contract system. These workers and designers all signed labor contracts. Moreover, the initial contract was only signed for three years."

The Red Empire collapsed at the end of 1991, and now it is the end of 1993. In other words, the contracts signed by these people only have one year?

Qin Tao only needs to pay one year's additional cost. After one year, these people have nothing to do with the design bureau and shipyard. They should sign a contract with Mingzhou!

Xu Zhengyang's eyes lit up. President Qin really calculated everything.

"President Qin, how did you know?" Zheng Ming asked curiously.

Qin Tao smiled: "My friend said so."

This is actually the experience of his previous life. He had been to a submarine design unit and communicated with the old Russians there. The other party talked about the experience of coming to the East: he signed a three-year contract, and after the contract expired, the design bureau didn't want it anymore, so he followed others to the East.

The Tianqingshi Design Bureau is so tragic. Since the collapse of the Red Empire, there has been no product, and a large number of people employed by the design bureau can only make a living on their own.

Today, Qin Tao suddenly thought of this, so he could boldly propose these plans.

The other party was not on guard at all, because no one took the labor agreement seriously.

Zheng Ming was very excited.

Although there are nuclear submarines in China, they are only at the level of the first generation of nuclear submarines in the West and the old Russians, that is, the problem of whether there are any or not has just been solved, and it is not advanced at all.

If this group of professional submarine designers from the old Russians go back, the second generation of nuclear submarines in China can be officially launched even with strong foreign aid!

Zheng Ming didn't sleep well that night. When he woke up in the morning, he had two dark circles under his eyes, and Qin Tao laughed at him.

Shipyard, closed production workshop.

The group continued to walk forward along the road they walked yesterday. At least 500 meters away from the river, a building that looked like a warehouse turned out to be the production workshop of nuclear submarines.

Yesterday, no one noticed it. It is estimated that even the reconnaissance satellites in the sky would not see it. There were already dense woods all around.

With a creaking sound, the door of the workshop opened, and everyone stepped inside, but Qin Tao stayed.

He pointed his finger at the side of the door: "There are still tapes hanging on your door?"

It has probably been a few years, and these strips are somewhat aged and cracked. However, it is definitely creative enough to install strips on a door that allows submarines to come out.

What are the adhesive strips used for? Seal it!

Can this kind of workshop be sealed?

"These are for sealing. More than ten years ago, when building the first Type 945 nuclear submarine, we found that the quality of many welds was not up to standard. Later we improved the production process because the airflow would affect the protective argon gas. , in order to reduce the flow of air flow, the entire workshop has been sealed.”

If it is an aircraft like the Su-27, especially for the titanium alloy components of the engine, a special welding room can be built. The welders wear the same equipment as astronauts. It is most suitable to weld inside the space.

However, for nuclear submarine shell welding, it is impossible to fill such a huge factory with argon gas! In that case, the consumption during the construction process will be astronomical.

Therefore, a method similar to argon arc welding is used, in which argon gas is passed around the weld. However, it is more stringent. The argon gas must be completely covered. If there is air flow passing through the workshop, the argon gas will be Blown away, resulting in poor quality welds.

Everyone sighed.

As expected, only Lao Maozi can handle titanium alloy submarines. Just this welding process costs a lot of money!

With emotion, everyone walked in. At this time, dozens of workers were working inside the workshop, and they could see that the welded components were being dismantled.

"The dismantling project started ten days ago. If you had come ten days earlier, you would have seen the completed components." Lapilov said.

This was just an afterthought. If it had really come ten days earlier and it hadn't been dismantled yet, they wouldn't have been able to come in and take a look!

"But it's not too late now." Qin Tao said: "You can dismantle the internal devices. Keep the useful ones that can leak secrets, and sell the useless ones to us. You don't need to touch this shell. When the time comes, , we will take them away directly!”

On the outside of the Type 945 nuclear submarine, the diameter of the non-pressure hull is about 12 meters, but the diameter of the internal titanium alloy pressure hull is about eight meters. At this time, several pressure hulls in the middle of the hull were built. The three inner decks of the eight-meter-diameter section have been welded together, and some devices have even been installed.

The disassembly work started from the inside first, and the outside was not touched yet, so the outer titanium alloy shell remained intact.

Like the two Kilo-class ships, it has also been idle for several years, but the titanium alloy shell is still shining, forming a sharp contrast with the rusty Kilo-class.

The casing has not been disassembled yet, so these titanium alloy casings are in good condition and have not been violently damaged by disassembly, which is really great!

However, when he said this, Rapilov felt a little embarrassed.

Do you agree or not?

Qin Tao thought of something and quickly explained: "Don't worry, even if we weld it together when we go back, it will be useless. Without the bow and stern, it is not a complete submarine!"

After dismantling, it’s just real scrap titanium alloy. What now? It's still in good condition. Will Qin Tao build it after buying it back?

Caipilov had this concern just now, but now Qin Tao's explanation reassured him.

It is incomplete. There is no beginning or end, only the middle. What use can it be? Qin Tao just didn't want workers to damage the precious titanium alloy when cutting, so he wanted it to be intact.

"We have always attached great importance to credibility. The Kiev purchased from the Northern Fleet was rumored to be renovated by the outside world. Now it has been turned into an aircraft carrier park for tourists to enjoy. If you are interested, you can also go and have a look. I will reimburse you for your round trip expenses and accommodation," Qin Tao said.

The renovation of the Kiev aircraft carrier park has put all the slanderous remarks in the face. Our Mingzhou Group will do what we say and do what we say we will do.

"Mr. Kvasa, why are you here?" At this time, Ravkovsky, who came with him, saw a person standing inside and couldn't help shouting: "And, Krasnopolsky Sir, are you here too?”

Looking at the two gray-haired old men, Ravkovsky was extremely shocked.

"Yeah, let's take a look. I heard that this Type 945 nuclear submarine is going to be dismantled. Let's... send it off." Kvasa said.

"Yes, when the Ulyanovsk was dismantled, I didn't catch up. Now I heard that this ship will also be dismantled, so I came to take a look. However, I didn't seem to see anything when I came. After all, Its nuclear reactor has not yet been assembled."

"Ravkovsky, these are all seniors, can you introduce them to me?" Qin Tao asked. At this time, he was also very excited. Because he already knew the identities of these two people.

"Of course." Lavkovsky immediately introduced: "This Mr. Kvasa was the previous chief designer of our design bureau. I was still his student. He designed the Type 945 nuclear submarine. Yes, I am just doing some modification work. This Mr. Krasnopolsky also retired the year before last. He used to work in the Experimental Design Bureau of Machinery Industry and was from our city, so he came back to our city to retire. "

These two people are both powerful. Kvasa started designing the Type 945 in the 1970s. After ten years of hard work, he designed this submarine. Definitely a seasoned veteran.

As for Krasnopolsky, it is even more powerful. Mechanical Industry Experimental Design Bureau, the name may sound very ordinary, but it is the most powerful nuclear reactor design bureau in China!

Although their Celestite Design Bureau designed nuclear-powered submarines, the nuclear reactors on them came directly from the Machinery Industry Experimental Design Bureau. Even the nuclear reactor of the nuclear-powered aircraft carrier came from there.

This trip was really rewarding!

Qin Tao sighed in his heart, quickly walked up and stretched out his hand.

"Two gentlemen, this is the boss of Dongfang Mingzhou Group. He came here with Dongfang's naval inspection team to buy our two 877 submarines and some scraps." Ravkovsky continued to introduce the two of them. Qin Tao.

Next, it was time to introduce Zheng Ming, but behind Zheng Ming, Deng Rui strode over and held Kvasa's hand tightly: "Teacher Kvasa, do you still remember me?"

Kvasa looked at the person in front of him carefully. In terms of age, the other person might be older, but the other person respectfully called him teacher. Decades have passed, and the years have left a mark on both their faces. There are a lot of wrinkles, but there is always something vaguely identifiable between the eyebrows.

"Are you Deng?"

"That's right, it's me. Decades have passed, but I never thought we could meet again!"

"Yes, according to the February 4th Agreement, we went to the East to help you master the construction technology of 633 submarines. After so many years, those submarines have long been eliminated, right?"

Saying these words made the naval personnel present a little embarrassed. Elimination? Submarines with that kind of technology from the Second World War are still our main force!

On February 4, 1959, the two sides signed the "Agreement on the Soviet Government's New Technological Assistance to the Chinese Navy in Manufacturing Ships", referred to as the "February 4th Agreement". The agreement stipulated that the Soviet Union would transfer the construction rights of the "6633" medium-sized torpedo submarine for a fee , provide drawings, equipment and equipment, and dispatch expert guidance.

According to this agreement, a large number of Soviet submarine experts came to China to participate in the construction of this submarine, including Kvasa.

After all, the Type 6633 submarine was designed by the Celestite Design Bureau, and of course their experts were responsible for the training. However, Kvasa was not the chief designer at the time, just an ordinary designer.

Although ordinary, the people in the East also respected them very much and regarded them as teachers, and the two sides established a deep friendship.

Recalling scenes from decades ago, Kvasha also had red eyes.

"It's not easy to get together again after decades." Qin Tao said from the side: "At noon today, let's go to the largest restaurant in the city for a drink. I'll treat you!"

Now that we have met, it is fate, everyone should have a good drink!

For Lao Maozi, he would never refuse this proposal.

Next, everyone continued to observe the K-534 submarine that was being dismantled. For our own designers, there was a lot to study about the submarine being dismantled, and everyone took it seriously.

Lao Maozi is also very generous. When he sees something that everyone is interested in, he will also introduce it. It should be the banquet at noon that makes them more enthusiastic.
