The Immortal Warrior: From Reverse Engineering to Forging Swords for the Country

Chapter 174 Deck Steel Problem

After a warm reception, Geng Xinzhong did not mince words and said to Zhang Zhipeng with a smile: "Comrade Zhipeng, are you here to inspect the aircraft carrier manufacturing capabilities of our Dalian Shipyard?"

Zhang Zhipeng smiled and said, "You guessed it right."

"However, with your current equipment, building an aircraft carrier is not enough."

Geng Xinzhong rubbed his hands, leaned forward a little, and said a little nervously: "We have shortcomings. If you point them out, we will make corrections as required!"

"We will keep changing it until it meets the requirements for aircraft carrier manufacturing!"

"I just hope that this task can be handed over to us. Tens of thousands of employees in our factory are looking forward to this day!"

Zhang Zhipeng said with a smile: "The first thing needed to build an aircraft carrier is a large dry dock, which requires a depth of at least 14 meters! I have inspected all your dry docks, and the deepest dry dock you have currently is only seven or eight meters. Far from up to par.”

Geng Xinzhong breathed a sigh of relief and said, "The Modu Shipyard certainly doesn't have such a deep dry dock!"

"As long as the country supports it, we can build a 14-meter-deep dry dock!"

"However, this is a bit difficult."

"Comrade Zhipeng, I also have some knowledge about building aircraft carriers. I see that the depth of Newport News Dry Dock, the largest dry dock in Lao Mo's family, is only 12.9 meters."

"Why do we have to emphasize the 14-meter-deep dry dock?"

Zhang Zhipeng said with a smile: "First of all, this is to make the construction easier when building the aircraft carrier."

"Secondly, the draft of an aircraft carrier is generally more than ten meters. If the dry dock is only 12 or 13 meters, it is easy to hit the bottom and damage the bulbous bow."

The bulbous bow of the aircraft carrier is located at the bottom of the warship, and its shapes include drop-shaped, angled and cylindrical shapes.

This device can help aircraft carriers or large ships offset the impact of waves and improve the ship's fuel utilization efficiency.

Generally, the fuel utilization rate of ships equipped with a bulbous bow can be increased by up to about 15%.

It also increases the buoyancy of the bow.

Therefore, large warships generally install bulbous bows.

Geng Xinzhong nodded and said, "I understand."

His brows furrowed. As a person who has been working in the shipbuilding industry for half his life, how could he not know how difficult it is to build a 14-meter-deep dry dock.

Choosing a location is a hassle.

It is also very difficult to build.

Because the aircraft carrier dry dock must be located on the seaside.

In fact, the dry dock may be just across a dock door from the sea.

If you are too close to the sea, the groundwater is often relatively shallow. Generally, there is groundwater six or seven meters below the surface.

Building a 14-meter-deep dry dock would be a bit too much for the pressure from groundwater.

Even if a dry dock of that depth is built with steel and concrete, it is very likely that it will be lifted up by groundwater.

Therefore, Geng Xinzhong is a little worried.

Zhang Zhipeng said with a smile: "I came to Dalian Shipyard this time to find a more suitable place to build an aircraft carrier dry dock."

"Director Geng, don't worry! Let's come up with a solution together and build a new dry dock!"

Geng Xinzhong heard what Zhang Zhipeng meant.

This dual academician and top domestic scientist seems to be inclined to hand over the task of building aircraft carriers to Dalian Shipyard.

"Thank you, Comrade Zhipeng! Then I will accompany you to have a good inspection at our Dalian!"

"Where do you think is suitable for building a dry dock? Let's make a report. There will be no problem!"

Zhang Zhipeng smiled and nodded and said, "Okay! I'm just waiting for your words!"

"Then let's walk around the Dalian Beach! Maybe there will be a surprise!"

The next day, Geng Xinzhong accompanied Zhang Zhipeng on the beach in Dalian to start the inspection.

Turning to the afternoon, we arrived at Xianglu Reef Bay.

Zhang Zhipeng came here and carefully identified the terrain here.

This is the place where the aircraft carrier dry dock was built in the previous life!

This bay is calm, with almost no strong winds and waves, and the water depth is quite suitable.

Moreover, the geology here is also quite good. There are rocks not too deep below the soil. Although there is groundwater below, there is not much groundwater. As long as the water is drained by the pump house, there will be no problem.

In order to verify his idea, Zhang Zhipeng asked Geng Xinzhong to bring in equipment to explore the underground conditions at the seaside.

This exploration further verified Zhang Zhipeng’s idea.

This place is definitely very suitable for building an aircraft carrier dry dock!
"Comrade Zhipeng, how are you doing here?" Geng Xinzhong looked at Zhang Zhipeng eagerly and asked.

Zhang Zhipeng smiled and nodded and said: "This place is very good. I think it will not be too difficult to build a 14-meter aircraft carrier dry dock!"

Geng Xinzhong was overjoyed: "Is it true?"

"Can we really choose a site here to start building an aircraft carrier dry dock?"

Zhang Zhipeng smiled and said: "I think there is no problem."

"However, we still need to carefully design how to build this aircraft carrier dry dock in the most appropriate way."

"In addition, as you know, an aircraft carrier outfitting dock will be built outside the aircraft carrier dry dock. This is also a very important supporting facility."

The so-called outfitting dock means that after the aircraft carrier has built its hull in the dry dock, seawater is put into the dry dock to make the aircraft carrier float, the dock door is opened, and the aircraft carrier is towed to the outer outfitting dock with a tugboat, where the aircraft carrier is weaponized. and other equipment configurations.

It is equivalent to fine decoration of a rough house.

Outfitting is very important and even takes longer than building a ship.

The aircraft carrier outfitting dock cannot be located just anywhere.

Geng Xinzhong was overjoyed. He thought to himself, it looks like there is a chance!
As long as the first domestically produced aircraft carrier can be built at Dalian Shipyard, it will definitely be a good opportunity for great development for Dalian Shipyard!

He nodded repeatedly and said: "No problem! I can mobilize a group of experts to cooperate with you to design this dry dock."

Zhang Zhipeng thought to himself, I actually don’t know much about the design and construction of dry docks.

Just use this opportunity to conduct an in-depth reverse engineering study.

Zhang Zhipeng said: "Then find me some experts in dry dock construction. Let's discuss it together, inspect other dry docks, and then come up with a set of construction design drawings."

Geng Xinzhong found the best and most experienced experts in dry dock construction and design at Dalian Shipyard to cooperate with Zhang Zhipeng.

Zhang Zhipeng spent time with these experts day and night, checking information and inspecting other shipyards on site. He was very busy.

It took him seven or eight days to finally improve his dry dock construction and design skills to the highest level.

In the process, he also conducted an in-depth investigation and exploration of the coastal areas of Xianglu Reef.

Finally, a place was selected to build the aircraft carrier dry dock and aircraft carrier outfitting dock.

Therefore, he began to conduct a feasibility analysis on the construction design plan of the aircraft carrier dry dock.

He scribbled on the design drawings, looking for the most suitable construction plan.

In the process, he overturned several design and construction methods one after another.

Eventually, he settled on a design.

He called this design and construction plan the "Caisson Dock Wall Type Dry Dock Wet Construction Design Plan."

This design does not include temporary water-stop cofferdams, so construction is very convenient, and most importantly, the construction period is quite short! And the cost will be lower!

The key to this construction design plan is to solve the problems of rising slurry and water stop, steel floating box at the dock entrance, lower dock channel, oversized pump room caisson and uneven settlement of unconsolidated foundation bed.

With the help of several assistants, Zhang Zhipeng spent more than ten days solving the complete construction technical plan and technical difficulties, and drew construction drawings.

After the drawings were completed, Zhang Zhipeng invited Geng Xinzhong over and asked him to bring all the key technical personnel for a meeting.

At the meeting, Zhang Zhipeng analyzed his plan in detail.

Geng Xinzhong nodded repeatedly after hearing this. He is worthy of being a top scientist at the national treasure level!

He was able to solve such a difficult aircraft carrier dry dock construction and design issue in such a short time!
Moreover, according to Zhang Zhipeng's design plan, the construction period is very short. It will only take more than half a year at most to build an aircraft carrier dry dock.

The cost is about more than 100 million soft sister coins.

After Zhang Zhipeng explained his design plan, he solicited opinions from experts.

There was no one on site who could offer constructive suggestions.

After the meeting, Geng Xinzhong and Zhang Zhipeng chatted.

Geng Xinzhong was a little uneasy: "Comrade Zhipeng, the construction of this dock should be funded by the state, right?"

Zhang Zhipeng smiled and said: "That's for sure! The state will allocate special funds."

"Let's do this! I'll call Director Zhao and ask him to come over and conduct an on-site inspection. After all, approving money requires his signature!"

Geng Xinzhong nodded repeatedly and said, "You are right!"

"Let Director Zhao make the final decision."

Zhang Zhipeng called Zhao Bingkun.

Zhao Bingkun was very happy when he heard that the construction location and construction design plan of the aircraft carrier dry dock had been determined.

"Is Dalian really suitable for building an aircraft carrier dry dock? Great! I've been waiting for your good news!"

"I'll be there right away!"

Not long after, Zhao Bingkun came to Dalian.

Zhang Zhipeng talked to him about his design plan to build an aircraft carrier dry dock at Xianglu Reef.

After Zhao Bingkun listened, he scratched his head and said, "I don't understand what you're talking about. If you say it's okay, then it's okay!"

"As for me, I will be responsible for making the final decision and giving the money!"

"We can't delay it any longer. It's already August 96! I'm just waiting for the aircraft carrier to start construction!"

"Then let's do it!"

As a result, the design and construction plan for the aircraft carrier dry dock and outfitting dock was finalized.

Dalian Shipyard is still responsible for the construction.

Of course, Zhang Zhipeng is still responsible for providing technical support.

After the construction of the aircraft carrier dry dock was settled, Zhang Zhipeng said to Zhao Bingkun: "Director Zhao, there is another very important matter that must be resolved as soon as possible."

"That is the design and manufacturing of large gantry cranes." "Aircraft carrier construction requires large gantry cranes, and one with a capacity of about 2000 tons is most suitable!"

Zhao Bingkun waved his hand and said: "Let the heavy machinery factories across the country bid. I think it shouldn't be too difficult to design and build this thing, right?"

Gantry crane is a necessary mechanical equipment for large-scale engineering construction and cargo terminals.

China is currently in the midst of a large-scale infrastructure construction boom, so there are still many R&D and manufacturing companies for gantry cranes.

It's really not difficult to design this thing.

But the manufacturing requirements are still quite high.

In the previous life, by the 21st century, basically more than % of the gantry cranes in the world were produced in China.

Similar footbath manufacturers have been squeezed to the point where they have almost no chance of survival.

Zhang Zhipeng smiled and nodded and said, "It's really not too difficult."

"Don't organize research and development. I suggest you just leave it to Modu Zhenhua to build it. They are considered the leading enterprise of gantry cranes in China."

Zhao Bingkun nodded and said, "That's fine!"

Just like that, Zhang Zhipeng wrote down the design and construction requirements, flew to Shanghai, and handed over the task to Zhenhua Heavy Industries.

In this way, the basic conditions for aircraft carrier construction are almost completed.

Next, Zhang Zhipeng went to Anshan Iron and Steel Company specifically to produce steel plates for aircraft carriers.

If you want to build an aircraft carrier in Dalian, the most convenient one to use just now is of course Anshan Iron and Steel.

The steel plates used in aircraft carriers are really important.

This matter must be resolved in advance.

It can be said that one-third of the engineering volume of an aircraft carrier is related to deck steel.

Deck steel is a special type of steel that requires high requirements and complicated processes to produce. There are only a handful of countries in the world that can produce deck steel on their own.

In previous lives, China had many difficulties in building aircraft carriers. Apart from dry docks, deck steel was the biggest difficulty.

In order to overcome the technical difficulty of deck steel in the previous life, Hua spent more than 500 days concentrating a large number of scientific and technological personnel before finally overcoming the difficulty and producing qualified deck steel.

Of course, Zhang Zhipeng was not willing to spend that long in this life.

Zhang Zhipeng also received a warm welcome after arriving at Anshan Iron and Steel Co., Ltd.

Ansteel Chairman Dai Xianghua personally received Zhang Zhipeng.

Zhang Zhipeng told him about the urgent need to conquer the aircraft carrier deck steel in order to build an aircraft carrier.

Dai Xianghua smiled and nodded and said, "The requirements for aircraft carrier deck steel should be relatively high special-grade steel, right?"

Zhang Zhipeng nodded and said: "Yes! The requirements are quite high. They must have high strength, large plate area, antimagnetic, high toughness, low temperature resistance, high temperature resistance, corrosion resistance and no deformation."

Dai Xianghua said: "Then our current products are definitely not up to par."

"But, it doesn't matter. As long as the country needs it, we will work overtime on research and development!"

“If foreign countries can do it, we can definitely do it too!”

Zhang Zhipeng nodded appreciatively, gave a thumbs up and said, "Mr. Dai, I admire you!"

"I am here this time to work hard with our technical staff to complete the deck steel as soon as possible."

In fact, the 052D deck steel is produced by Baosteel in Shanghai.

However, the deck steel of a destroyer is still incomparable to that of an aircraft carrier.

Still have to develop it from scratch.

Dai Xianghua waved his hand and said, "Comrade Zhipeng, we all have to learn from you! You have helped the country solve many military and technological problems over the years!"

"With your participation, I believe that the issue of aircraft carrier deck steel will be solved soon!"

Zhang Zhipeng worked with Anshan Iron and Steel's technical staff to tackle the technical difficulties in manufacturing super-large aircraft carrier deck steel.

In fact, Zhang Zhipeng has already mastered the technology of deck steel.

The complete set of drawings of the Varyag aircraft carrier also includes the manufacturing method of deck steel.

However, even if there is a manufacturing method, it still needs to be explored in practice.

Exploring little by little, we found an effective method of mass production.

Zhang Zhipeng is leading technical staff to tackle key problems in Anshan Iron and Steel, but he said that a delegation from the old mold family came to visit in the capital.

The delegation was led by Keating.

When Keating met with Zhao Bingkun, he said that they could assist China in building an aircraft carrier and provide a full set of technical assistance.

Zhao Bingkun naturally didn't believe in Lao Mo.

However, he felt in his heart that if he could work hard with Lao Muxu and get some skills from Lao Muxu, it would be okay.

Zhao Bingkun had a fight with Keating and said he would consider their proposal.

After meeting with Keating, Zhao Bingkun immediately had a phone call with Zhang Zhipeng.

He told Zhang Zhipeng what Keating meant, and then said with a smile: "I think the old lady is deceiving us, what do you think?"

Zhang Zhipeng smiled and said, "Is there any need to say it?"

"They actually want to deceive us and make our aircraft carrier plan abort."

"Wasn't the lesson learned from Yun Shi that year profound enough?"

Zhao Bingkun said with a smile: "I won't believe them either."

"I just feel like I can have a hard time with them and see if I can get some aircraft carrier technology from them."

Zhang Zhipeng smiled and said: "Give up your illusions and be self-reliant!"

"It's better to believe that there are ghosts in the world than to believe in Old Mo's mouth!"

"You want to get a little benefit from them? They will make you pay ten times and a hundred times the price!"

"Director Zhao, our aircraft carrier plan is going smoothly. Don't think about trying to get skin from a tiger."

Zhao Bingkun said with a smile: "I'm a little naive."

"I will reject them immediately!"

After Zhang Zhipeng made this call with Zhao Bingkun, he shook his head: Lao Mo is the best at rhetoric and strategic deception, so he must be thinking of something else.

The best way to treat this country is to stay away from it. It will be bad luck to get too close to it.

Therefore, you really need to be vigilant when dealing with old mold!

In the development of the military industry, we must adhere to independent principles and policies without wavering at all!
Because once you fall into the arms purchase trap and waste your own R&D and production, in the end even your own country's security will be at the mercy of others!

For example, the third brother next door, most of the weapons are purchased from outside, because outsourcing weapons can make some of the third brother's people soft with kickbacks.

Not only were their Wanguo brand weapons difficult to maintain, but in the end, the third brother could no longer even produce cannonballs and bullets independently. Would you say it’s scary?

Although such an episode made Zhang Zhipeng a little unhappy, he quickly adjusted his emotions and once again devoted himself wholeheartedly to the research and development of deck steel.

Through research, Zhang Zhipeng discovered that there is a very special kind of spherical flat steel in deck steel that is essential for manufacturing deck steel.

He began to lead the team to develop the technology for producing flat bulb steel.

In just three or four days, he mastered the production of flat bulb steel and summarized the most efficient production process...

After testing the flat ball steel produced by his team, the performance in all aspects was excellent.

Suddenly, the entire Anshan Iron and Steel Company was boiling.

During the test, Dai Xianghua was nearby. After seeing the performance of this bulbous steel, he said excitedly: "This is the best special steel I have ever seen."

"Comrade Zhipeng, I really didn't expect you to be able to do it in such a short period of time."

Zhang Zhipeng said with a smile: "The creation of spherical flat steel has solved a big problem. However, we still need to solve the problem of production equipment and strive to produce the largest area of ​​deck steel."

Dai Xianghua said with a smile: "It's just a big rolling mill!"

“If we design an extra large and extra wide rolling mill, wouldn’t the problem be solved?”

Zhang Zhipeng nodded and said, "How about taking advantage of the situation and building us a 10-ton pressure special rolling mill?"

In a previous life, Anshan Iron and Steel Co., Ltd. specially customized an ultra-wide rolling mill for the purpose of building aircraft carrier decks. It was known as the 100,000-ton rolling mill, the largest in the world!
Now, under the leadership of Zhang Zhipeng, it will be released ahead of schedule.

In fact, there are no special technical difficulties in large rolling mills.

However, he still participated in the design and manufacture of the world's largest rolling mill.

His participation is mainly to add CNC functions, which can make rolling mill control more intelligent.

The manufacturing task of the large-scale rolling mill designed by Zhang Zhipeng was handed over to Huaguo No. 1 Heavy Industry Machinery Company.

In order to follow up on the design and production of this large rolling mill, Zhang Zhipeng returned to Beijing from Dalian.

He specially asked Huaxing Company to produce a series of sensors and CPUs, and he also designed a control program for this large rolling mill.

In this way, almost half of the manpower can be freed, and aircraft carrier deck steel can be produced more accurately, improving the yield and improving production efficiency.

After solving the problem of the large rolling mill, it was already October 1996.

On this day, Yu Chengdong called Zhang Zhipeng. He told Zhang Zhipeng that the Hongqi concierge car had been manufactured in accordance with the modification requirements of the relevant superior departments.

Yu Chengdong said with a smile: "The quality of this car is absolutely excellent. The special bulletproof glass can withstand even if it is smashed with a sledgehammer."

"Even if a grenade explodes under the car, it will not cause any damage to the chassis."

Originally, as planned, the Hongqi limousine would be completed in June.

However, the higher-level departments still had very high requirements for this car, and they kept putting forward suggestions for modifications. Later, it was delayed until October when it was finally completed.

Zhang Zhipeng said with a smile: "Has it been accepted by the superiors?"

Yu Chengdong said: "It has undergone three rounds of acceptance tests, and the leaders are still very satisfied."

"The quality, performance and safety of our limousine are absolutely unparalleled. It is more than one level better than the old Cadillac limousine!"

Zhang Zhipeng said: "Then let's see what the superiors say! If the superiors are satisfied, we will start mass production immediately and complete the task!"

It is a great honor to be able to produce a powerful limousine car!

Isn’t it that the reason why Cadillac is highly respected by many people around the world is because it is an old-fashioned courtesy car?
The concierge car is a facade, but what Zhang Zhipeng is actually most concerned about is mass-produced cars for the market! And what he wants to start is the revolution of mass-produced cars in China!
Zhang Zhipeng originally wanted to go back to Chang'an to see the situation with his own eyes, but at this time, Zhao Bingkun called him and said that the leader wanted to see him.
