Chapter 536 We Are Not Almighty Experts
After the meeting, Yang Dakai, general manager of Jiangnan Shipbuilding Group, quickly called the chairman of the shipbuilding group at the headquarters, and explained clearly the situation of seeking help from Xinghai Group for the difficulty in developing the aircraft carrier deck.
"I'm not familiar with Mr. Mu. My face is useless in front of others. Let me ask the superior."
The chairman of the shipbuilding group also had a headache, so he asked Yang Dakai to wait for a while and directly called his superior, the relevant leader of the machinery department.
after one day,
Mu Yang received a call from Zhang Lan, the leader of the machinery supervisor.
"Mr. Mu, Jiangnan Shipbuilding Group found me after a few laps, and entrusted me to ask you, is there any way to solve the material problem of the aircraft carrier deck?"
"Carrier deck? We didn't do that."
When Mu Yang heard about Jiangnan Shipbuilding Group, he knew the nature of this group company, which can be said to be a half-jungong state-owned enterprise.
"Yes, I guess you will not develop this either. The Jiangnan Shipbuilding Group also guessed it. Now they have encountered the problem of materials for the deck of the aircraft carrier. Let me mention this to you. I guess you also guessed it. It is to manufacture aircraft carriers. The first Guan was stuck with the materials, and they thought of the strength of your company, and they might be able to develop aircraft carrier decks."
"Leader, we are not all-round experts." Mu Yang didn't know whether to laugh or cry.
"Hey, I know. They searched for connections for a few times and came to my side after begging. Please ask me to ask. If you don't have time to develop, then forget it. I also know that you have a lot of scientific research tasks.
But to be honest, you also know that the domestically-made aircraft carrier has always been what the country wants to realize, and it is of great significance.
You have developed an afterburner turbofan engine for Jun, which has solved a big problem for Kong Jun. It is currently being used in new fighter jets and is under development. If you are free, you can also give me some guidance.
Oh, speaking of the aircraft carrier deck, it is very difficult..."
Mu Yang listened to him nagging for a long time, in fact, it is not difficult to solve the matter on the aircraft carrier deck, isn't it just a matter of achievement.
However, Mu Yang didn't want to agree to others so quickly.
If it was so easy, more people would come to him in the future, wouldn't he be bored to death.
"Leader, there are too many scientific research tasks here, and the rocket project and computer project are both enough headaches."
Zhang Lan is also very helpless: "I know, I'm also embarrassed, how about this, if Xinghai Group's computer is launched, I will help you sell it to various departments, ZF procurement should not be a problem.
In addition, it is not for nothing, you are not short of money, but it should be produced by Jiangnan Shipbuilding Group, if it is really successfully developed, the result will of course be yours, you can do whatever you want, and the country will take care of it in other ways Make compensation. "
Hearing so much from Zhang Lan, Mu Yang didn't know what to say.
ZF purchases computers, this deal is okay, even if he has confidence in his computer products, it is more worry-free to have ZF purchase.
If he really develops aircraft carrier deck materials, he does not need Jiangnan Shipbuilding Group to pay any fees, and how to deal with the results is his own business.
The Xinghai Group helped solve the engine problem of the C919. SAIC cooperated with the Xinghai Group and directly purchased the engine from the Xinghai Group, which made money;
Helped solve the afterburner turbofan engine for Jun, the country still doesn't know how to compensate Xinghai Group, except for some scientific research funds with land compensation, it is still far behind.
In fact, Mu Yang didn't have any needs. Whatever the state could give or help, the higher-ups gave, and Xinghai Group was already very laissez-faire.
It can be said that as long as Mu Yang does not betray the country, other mistakes are not a problem.
Some time ago, a newspaper office slandered the Xinghai Group, and the higher-ups directly cleaned it up, and there was no need for the Xinghai Group to take action.
He himself is also interested in aircraft carriers, which man doesn't like it?
Of course, the construction of an aircraft carrier has become the most difficult system engineering in today's shipbuilding industry, even an impossible task.
These key technologies include: steam catapults (and his upgraded electromagnetic catapults), arresting cables and large elevators.
However, Xinghai Group's Junyong engine directly solved these three key technologies.
A carrier-based aircraft with powerful thrust does not need a catapult;
Equipped with a three-way nozzle, the carrier-based aircraft can achieve an emergency stop without the need for arresting cables.
"Leader, the deck of the aircraft carrier is very thick, and we don't have a rolling mill of more than 50,000 tons, so we can't mass-produce it." Mu Yang knows the trouble of producing high-strength ultra-thick plates, and he has no interest in building a large number of large-scale equipment.
For high-strength plates over 70 mm, the rolling width may reach four to five meters. Even rolling under high temperature conditions requires a lot of force. A hydraulic press of several hundred tons cannot handle it at all, and it would take tens of thousands of tons of rolling. Machines, preferably 100,000-ton level, can produce wider plates.
For aircraft carrier decks, the bigger the board, the better. First, it can reduce welding seams and welding workload, which can also reduce welding deformation;
The second is that the unevenness should be smaller. The aircraft carrier does not have such strict requirements on the unevenness. The unevenness should be less than 5mm/m. Take off, not to mention the aircraft carrier deck that requires a higher flatness.
"I know, as long as you develop the technology, you can sell the technology to the steel mill, or sign an agreement to authorize the production, and the steel mill will manufacture it."
"Then let the other party put forward the relevant standards and requirements. I know a little about the situation on the aircraft carrier deck, but to be honest, I'm not sure. This thing is too difficult."
"Okay, on behalf of them, I would like to thank Xinghai Group. The development of the aircraft carrier deck is very difficult. Just do your best. I will talk to Jiangnan Shipbuilding Group later and ask them to send experts to explain the situation clearly. It would be better to communicate face to face. .”
"Okay then, let's talk when we meet."
After Mu Yang finished talking with Zhang Lan, he calmed down and thought about the aircraft carrier deck.
This matter is very simple for him, just spend achievement points to buy technology from the reading system.
However, he couldn't take it out so easily, and he didn't want to give away the technology so easily.
The high-strength thickness can be used not only on the deck of the aircraft carrier, but also on the tank, which is very useful.
For aircraft carriers, the greater the strength of the aircraft carrier deck, the better. Reducing the amount of steel can reduce the weight of the hull, improve the maneuverability of the aircraft carrier, increase the speed, and lower the center of gravity, making the hull more stable.
Open the reading system, the achievement point store, and directly search for the technology of high-strength alloy steel plates in the ordinary shelves. It is required to filter according to the earth's resources, and at the same time, it is required to have a toughness of more than 15%, good welding performance, and low magnetism.
Soon, tens of thousands of copies of technology will emerge.
Too much.
The yield strength is above 690MPA.
Mu Yang screened again, requiring the yield strength to be above 790MPA, and the technical quantity was only over 3,000 in an instant.
After roughly looking at the introduction of these technologies, I found that there are still many with a yield strength above 890MPA, and even the highest one is above 1550MPA.
[Note: High-strength plates are generally quenched and tempered + tempered, and the factory state of the materials here is the quenched and tempered + tempered state]
Higher level, no more.
This is due to the limitation of the earth's elements. If the material formula requires elements that do not exist on the earth, they cannot be produced.
With the current domestic steel technology, it is also achievable to produce high-strength steel plates with a yield strength of 710-1550 MPa.
However, it is extremely difficult to produce thick plates over 50mm with good toughness, good welding performance and low magnetic properties.
After layers of screening, there is no such technology in China.
Mu Yang screened again, choosing a technology that is easier to implement and does not require too many achievement points.
"A hot-rolled high-strength steel with a yield strength of 960MPa and its production method and process"
This is an alloy design using C-Mn-Cr-Ni-Nb-Ti-B, which belongs to chromium-manganese-nickel-titanium steel, medium alloy ultra-high strength steel.
Mn and Cr adjust hardness and strength, Ni and Ti adjust toughness, and titanium also has corrosion resistance. Aircraft carrier decks are often eroded by seawater. This alloy design is more suitable for aircraft carrier decks, and the alloy composition is not high, and the carbon equivalent is also low. It is not high, and trace elements are added to increase the welding performance.
The yield strength standard is above 960MPa. It does not mean that it will be 960MPa when it is produced, but above. For example, 1000MPa is also in line. How much it can reach depends on the actual situation, but it will not float too high, and it will definitely not exceed 1200MPa.
Technical Introduction The tensile strength can reach over 1200MPa, the elongation can reach 17%, and it still has good low-temperature toughness at minus 46 degrees Celsius.
Low-temperature toughness is also very important. If not, even if the toughness is very good at room temperature, it will be very brittle at low temperatures. For example, Q235B is brittle below minus 40 degrees Celsius.
Mu Yang spent 50 achievement points to buy this technology, but it still feels a bit painful.
This technology cannot be applied for a patent for invention. It is better for the country to award him some honors and let him take back some achievement points, otherwise it will be a big loss.
Therefore, the difficulty in asking him to develop technology lies in the achievement point, and the technology must be kept secret.
If it weren't for the sake of the domestic aircraft carrier, Mu Yang would not agree, his achievement points are not cheap.
When I came to the supercomputing center on the 104th floor, it took half a day to output the data.
After waiting for a month, Mu Yang gave the materials to the company's material project team for them to develop.
It will take at least three months before Mu Yang will show the technology.
...
Yang Dakai got a reply from his superiors, and Mu Yang, chairman of Xinghai Group, was willing to approach them and ask them to bring a team of experts to discuss it. Whether it can be developed in the end is another matter.
After confirming, Yang Dakai was very excited. First, he didn't expect Mu Yang to be willing to help them. Second, it was a great honor to meet him in person and discuss cooperation with Mu Yang.
Yang Dakai immediately summoned relevant experts to his office to explain the situation.
"Mr. Yang, Mr. Mu is really willing to help us?"
Hearing Yang Dakai's words, the three experts were very excited.
In particular, Lao Liang, a material expert, immediately smiled, feeling that his body in his sixties was rejuvenated and refreshed, and the sense of decadence these days disappeared immediately.
"Don't doubt it, I've already confirmed it. Could it be that the superiors will lie to me about this kind of thing? Besides, someone from the Xinghai Group called to ask us when we are going to leave. Pack your luggage today, prepare the documents, and leave tomorrow. Don't go in front of people, you can't explain the situation clearly."
"Okay, whether it's successful or not, we do thank Mr. Mu."
"In this trip, in addition to solving the issue of the aircraft carrier deck, we also have to learn from the Xinghai Group their advanced management models and scientific research ideas with a learning attitude."
the next day,
At one o'clock in the afternoon, Yang Dakai and three experts arrived at H City Airport.
The personnel department of Xinghai Group sent a commercial vehicle to pick them up.
Jiangnan Shipbuilding Group has a long history and is not small in scale. It currently has 20,000 employees and a shipbuilding base of 8,000 mu. It is the largest shipbuilding company in China, and the general manager Yang Dakai is not low.
However, in terms of the company's technical strength, it is far from being able to compare with Xinghai Group.
When he came to Xinghai Group Industrial Park, Yang Dakai looked out the window and said to Lao Liang: "Our group is big, and shipbuilding basically occupies a large area, but Xinghai Group gives me a different feeling."
"Studying cutting-edge technology, every technology can lead the development of the world.
When we are still working hard for the world's first-class, there are only stars and seas in front of people, maybe it is because of this that there is an illusion. "
Yang Dakai was a little bit emotional, and admired such a technology company, and it was still a black technology.
Xinghai Group's HR Department arranged for them to stay. The company's guest house hotel has been put into operation, and the address is near Xinghai Home.
When they came that day, it was impossible to see Mu Yang all at once. The personnel department replied to them: the appointment time is at ten o'clock tomorrow morning.
On the third day, at nine o'clock in the morning, the personnel department sent someone to pick them up, and after a while, they arrived at Xinghai Building.
Came to a small conference room, first met Ying Zuci, the technical manager of Xinghai Group's special materials project team, the two sides chatted for a while, and when it was almost ten o'clock, Mu Yang arrived.
After the two parties greeted each other, Mu Yang asked the other party to tell the story of the aircraft carrier deck.
After about ten minutes, Mu Yang and Ying Zuci both figured out the situation.
After hearing this, Mu Yang stood up, sipping tea while pretending to be thinking.
Yang Dakai and the others felt that Mu Yang was a little embarrassed. They threw such a difficult problem to the Xinghai Group, and they felt a little sorry and at the same time a little uneasy.
For a short while, the atmosphere in the entire meeting room was a little depressed.
After Mu Yang felt that the atmosphere was about the same, he turned to Yang Dakai.
Sensing the gaze of the young man in front of him, Yang Dakai, who is in his fifties, was a little nervous.
Mu Yang looked away, smiled, and said: "Well, Mr. Yang, we will set up a project team to develop this matter, and if there is any progress, we will tell you the situation.
However, I can't guarantee that the research and development will be successful, and the time will be set for half a year.
In short, I am looking forward to the realization of the domestic aircraft carrier, and will pay close attention to the research and development of the aircraft carrier deck. "
Mu Yang tried his best to extend the time, but he might tell them the results within three or four months, so that they would appear pleasantly surprised.
As soon as Mu Yang finished speaking, Yang Dakai and others were overjoyed and breathed a sigh of relief, really afraid that Mu Yang would not agree to help them.
"Thank you, Mr. Mu, I also understand the difficulty of scientific research, and no one dares to say that once a project is approved, it will be successful.
I am still a little confused, how much research funding and labor costs are appropriate? "Yang Dakai said gratefully.
Mu Yang sat down and said: "If the development fails, we don't need any research funding or labor costs from you.
If it really succeeds, if we produce, Jiangnan Shipbuilding Company will purchase according to the market price;
If we do not produce, we will sell the technology to domestic steel mills and let them produce. How to negotiate the purchase price is a matter between you and the steel mills. "
"Okay, I see."
"Well, I have some matters here, so I won't accompany you for now. You should communicate more with Manager Ying. He will be responsible for this matter."
"Thank you, Mr. Mu, you are busy first." Yang Dakai knew that Mu Yang's time was precious, and it was good to spare half an hour to meet him, so he stood up and shook hands with him.
The other party promised and arranged for a technical manager to interface with them, which also shows that he attaches great importance to this matter.
Other visitors also shook hands with Mu Yang to express their gratitude.
half an hour later,
Yang Dakai and the experts left Xinghai Building.
At this time, they were in the mood to appreciate the Xinghai Building.
"This Xinghai Building is magnificent and magnificent, so beautiful."
"Yes, I didn't expect that Mr. Mu really agreed." Old Liang said easily.
"It can be felt that he has a different attitude in doing things. He is very efficient, not verbose, and he doesn't talk around. People who really do scientific research are different."
Yang Da laughed and said that he originally planned to go to the Xinghai Group's workshop to learn about their management model, but it didn't feel right. They saw layers of protection from entering the gate to entering the Xinghai Building, and they also knew that Xinghai Group was very secretive about technology. It's important, it's impossible for others to let them wander around at will, and finally didn't propose to Ying Zuci, so as to avoid embarrassment after being rejected.
Instead of going to the workshop of Cheng Xinghai Group, they planned to visit the smart city and see what the future mayor of the city would be like.
On Muyang's side, after dealing with the matter with Jiangnan Shipbuilding Group, he wants to go to the satellite project laboratory to have a look.
The rocket base is ready to actually launch satellites, five of which will be put into use at the same time.
It's not that one star can carry five satellites, this is only in the experimental stage, and when the time is ripe, the star network will be launched.
