I! Pretending to Be Reborn, Director of Doomsday Hoax

"The sun goes out."

Dai He's expression was shocked. When he connected these things together, he was frightened.

"Two comrades, let's go and meet Director Xu!" He said, suppressing the shock in his heart.

Dragon Kingdom, Dangerous Situation.

Xu Qiu leaned back in his chair, reviewing the materials from all over the country.

"Director Xu, at present, the design of the carriage of the nuclear-powered train has been completed!"

Ji Chengping, who hadn't seen him for a long time, came to the crisis situation again.

The last time he came here, he accepted Xu Qiu's appointment and officially became the designer of this big country's nuclear power dragon!

Become Xu Qiuxia's chief designer!

And for the second time, this great nuclear-powered giant dragon already has a prototype...

Ji Chengping took out a stack of documents from his pocket.

The edges of each sheet are frizzy, and it can be seen that it has been flipped through countless times.

"Director Xu, this is... your "Nuclear Power Train Structural Design, Control System and Running Track Engineering Drawing",

We have gathered more than 50 experts, and realized the modern technologies related to materials, machinery, electronics, computers and controls, as well as the miniaturization of nuclear power reactors and the miniaturization of cooling systems, and completed your entrustment to us! ! " Ji Chengping was leaning on crutches, his body was tall and straight.

He has never been so proud of himself for a moment!

Behind Ji Chengping are the other five main engineers and designers. They are also proud at the moment, excited that they have completed Xu Qiu's perfect design!

The entire nuclear power train includes the front, car body, bogie, vehicle connection device, brake device, vehicle internal equipment, traction drive system, nuclear energy kinetic energy conversion system, reactor, cooling system, and automatic control system..... .

"Director Xu, your "Nuclear Power Train Structural Design, Control System and Track Engineering Drawings" back then was [-] pages long, but these [-] pages recorded crucial technologies and technologies.

We continued to refine these 3000 pages, and expanded more than [-] taels to more than [-] pages, and finally prepared the prototype of a carriage! "

After Ji Chengping finished speaking, his respect for Xu Qiu had climbed to the extreme.

These twenty pages have solved all the difficult technical difficulties and technologies.

All they have to do is tinker with the details!

The scientist responsible for the energy of the nuclear power train is also the manager of the management and control department of the Longguo Nuclear Power Plant,

He once personally supervised the production of the first nuclear power plant in Longguo, and his achievements in nuclear power and nuclear energy utilization are unmatched by anyone in the country.

Even in the international community, this old man enjoys a great reputation.

At this moment, he only had endless respect for Xu Qiu, and said:

"Director Xu, your calculations were not wrong at all. Based on the calculation of the nuclear power dragon at 250 kilometers per hour, its daily power consumption is about 235 degrees, and the power consumption is about 70 degrees per hour. Our trains , relying on uranium 235 nuclear fission, in the case of complete fission, the energy produced is extremely huge, more than [-] grams of uranium [-], is enough to drive a nuclear-powered dragon for a year!

For the miniaturization of the cooling system, we have made the core smaller according to your plan, and the resulting disadvantage is that the cooling system cannot bear too complex a structure, and the control ability of the core temperature may be weakened... Therefore, we follow your According to the requirements, the entire cooling system has been made into three layers! "

When everyone thought of the cooling system, they unconsciously praised Xu Qiu's exquisite design.

The first floor is fully enclosed,

Inside is the core, which contains only the core's liquid cooling medium.

AVr- J—Zr/v-, SZ

Younger brother—layer and younger brother layer two are connected,

The temperature control system and cooling equipment are also stuffed inside.

In the outermost layer, heat insulation and cold-proof materials are installed on the surface.

The entire cooling system uses cold-proof materials that can withstand extreme low temperatures.

Today in the world, there is no nuclear energy utilization system more sophisticated than the nuclear energy cooling and power plant inside the nuclear power dragon!

When the Little Ice Age is approaching, the nuclear energy system of the nuclear power dragon has already taken shape.

Next, it only needs to be miniaturized and adjusted for stability, etc., before it can be officially put into use.

Wang Feipeng, a manager of the car body material development department, said:

"Moreover, the shell of the carriage we used was improved again on the basis of extremely cold steel.

We have adopted advanced manufacturing technology to prepare extremely cold steel with high cleanliness, high uniformity, and ultra-fine grain characteristics. Compared with ordinary extremely cold steel, the strength and toughness are improved, and the service life of steel is also greatly increased!Moreover, this kind of steel also incorporates the characteristics of ultra-high-strength steel, and its strength is terrifying! ! "

Wang Feipeng waved his arms.

Ultra-high-strength steel bears very high stress, generally the yield strength is greater than 1180Mpa, and the tensile strength is about 1380Mpa

At the earliest time, on the basis of AISI4130 and 4340 steel, the people of Meiguo changed the heat treatment process, adopted quenching and low temperature tempering, obtained tempered martensite structure, and increased the tensile strength of steel to above 1600MPa.

This is also one of the reasons why Berryland Aerospace made great achievements that year.

Although before,

Longguo is a big steel country with a large number of excellent steel products.

However, the cutting-edge steel technology is still comparable to Berry Country, and even inferior to Berry Country in some fields.

And with the advent of extremely cold steel,

This strange species suddenly appeared in the iron and steel of the Dragon Kingdom!

With its extreme cold resistance, it directly dominates the steel world and becomes the only steel material that can be used in the era of extreme cold!

after that,

Under the guidance of Xu Qiu, the members of the Capital Iron and Steel Group, who had developed the extremely cold steel rails, worked hard again,

Finally, in cooperation with the Nuclear Power Changlong R&D Department and the Car Body Material R&D Sub-Department,

After many experiments, it was decided to use the dispersion strengthening effect of low carbon martensite and precipitated alloy carbides,

The prepared extremely cold steel not only has high strength and toughness, but also has high stress corrosion resistance.

Moreover, its tensile strength is 2350MPa, fracture toughness reaches 190MN m, and its stress corrosion resistance is very good!

"However, there is still a shortcoming of the current material specially supplied to the nuclear-powered dragon carriage..." Wang Feipeng said with sad eyes.Xu Qiu turned his gaze.

Wang Feipeng said: "Our production technology is not enough. Back then you gave the production line of extremely cold steel rails, which was more than 100 years ahead of the human world.

And this new type of extremely cold steel specially supplied to nuclear-powered carriages may have higher performance requirements and other aspects. I am afraid that the only way to solve it in a short time is to pile up the amount to fight against the failure rate and forcibly increase this. production of steel. "

Ji Chengping was silent.

Their arctic rail cars were indeed prepared.

However, only two verses.

But each section has a length of 120 meters, and its width and height have created the history of trains, which is unprecedentedly huge!

The disaster resistance of this kind of train may reach an extremely terrifying level...

And the cost of research and development is calculated in tens of billions!

The price of a carriage exceeds [-] billion!

In the past, this was an impossible project.

However, now that the treasury is open and a large amount of materials are released,

The country is smelting iron and steel, mining ore frantically, supplying raw materials,

In this case, produce at any cost.

Only Ji Chengping could develop it.

"Director Xu, if the production process can be improved again, the resources saved and waste avoided may be in the hundreds of millions.

"However, the production process of steel has been improved to the limit, and it is almost impossible to upgrade it." There was also sadness on the faces of everyone.

Yes.

Everyone present here is a well-known figure in the field of machinery and steel production, and has extremely deep attainments in this area.

They were already unable to see through the original extremely cold steel rail production process.

What's more, on this basis, ask Xu Qiu to give a new production process...

Xu Qiu, who was sitting on the chair, thought for a long time, said, "I will deal with this matter later, and then I will go to your nuclear power Longlong R&D Department to solve this problem."

"This.…"

"Director Xu?!"

Everyone was horrified, and their breathing was short of breath.

On the premise that it has been more than 100 years ahead of the achievements of the human machinery industry, can it be improved again? !

Is Xu Qiu really human? !

Wang Feipeng's pupils widened. As a scientist and chief engineer of the car body material development department, he felt that his world view had been refreshed at this moment!

This thing, can it really be said to improve?

The age of mankind is measured on the basis of hundreds of years, or even ten thousand years.

From the Stone Age, to the Bronze Age, and then to the Iron Age, there are countless human craftsmen and scientists working hard and studying for hundreds of years...

don't say anything else,

As for the extremely cold steel rail production technology proposed by Xu Qiu, which shocked the world...

Without Xu Qiu, it would probably take decades, more than 100 years for the entire human mechanical genius, engineering genius, scientist, and scholar to gradually perfect and polish this production process step by step! Within an hour, bring this craft up,

An era, within this hour, has advanced by leaps and bounds and ushered in extreme technological innovation! !

Of course, until today, the production process of this extremely cold steel rail is still the highest level of state secrets.

Currently, there are only three places in the country that have the execution core technology of this production process.

The first is the Capital Iron and Steel Group.

The Capital Iron and Steel Group headed by Wang Xincheng is now the largest enterprise in the country that produces extremely cold steel rails.

Two-thirds of the extremely cold steel rails in China come from this top steel factory!

After the advent of the extremely cold steel rail, a major reshuffle was carried out within the Capital Iron and Steel Group.

All workers with difficulties and unstable factors were transferred to other steel groups to produce ordinary steel.
