I! Pretending to Be Reborn, Director of Doomsday Hoax

Wang Xinke sat in the first place, his face was gloomy, and he didn't say a word.

More than a dozen engineers from the Capital Iron and Steel Group discussed for more than an hour, but failed to finalize a final design plan...

One can imagine how difficult it is to develop this kind of extremely cold steel! !

"Let's solicit proposals from the whole country."

Wang Xinke took a puff of cigarette, his eyes were melancholy.

The technological requirements for extremely cold steel rails are too high, and many parameters cannot be determined now.

With the existing forging method, it may be difficult to produce steel that meets the standards of the Dangerous Bureau. However, the Dragon Kingdom is full of talents, and there are always strange people who have a way.

After half an hour.

[Capital Iron and Steel Group]: At the request of the Emergency Bureau, the group will produce a batch of extremely cold steel rails, solicit low-temperature reliable steel rails, extremely cold steel smelting, and manufacturing talents from all over the country. Those who provide ideas and clues will be rewarded according to the value. 2 million.If adopted, a one-time reward of 10 million will be awarded, and he will be hired as a senior engineer of Capital Iron and Steel Group, enjoying an annual salary of 5 million before tax.

As soon as this notice was posted, the whole circle exploded.

A railway engineer was shocked: "A one-time reward of 10 million, and an annual salary of 5 million!"

"Oh my god, the Capital Iron and Steel Group has really spent a lot of money!"

"No, take a closer look, this is an order from the Emergency Bureau! It's equivalent to working for the Emergency Bureau!"

"Extremely cold steel rails, who can tell me what else the country wants to do? Why produce extremely cold steel rails!"

"Do you want to build a train on the surface? How is this possible!"

now.

Du Niang post bar, railway bar.

New posts keep coming out, and the whole post bar is discussing this matter.

[Puchang Train Project. Hibernating Snow]: Extremely cold steel rails, extremely cold steel, I seem to guess what great project the motherland is going to carry out again!The era of large infrastructure, the era of large agriculture, and then the era of large demolition, is it now... the era of large trains?

[Railway Engineer. Leng Bingning]: I think, if you want to produce this kind of steel, you must increase the purity of the steel, increase the beneficial alloying elements, etc. to improve the performance, but... these auxiliary measures Boost performance is pretty limited!

[Designer of Hunan Provincial Railway Line [-]. There is a cat on a rainy day]: 'Leng Bingning' is right.Although measures such as purification and alloy addition can improve performance, they are very limited.As for the extremely cold steel needed by the country, I predict that it may not be so simple!

The three northeastern provinces of our country, as well as Xiongguo and other regions, all have mature forging and synthesis processes for minus [-]-degree steel. It is easy for the Capital Iron and Steel Group to produce them!

But they released a reward of tens of millions and an annual salary of one million to collect proposals from across the country... I dare to conclude that this extremely cold steel must maintain a high impact toughness below minus two hundred degrees!

[Tiandu high-speed train marshalling track engineer. Afterglow sunset 1971]: If you want to greatly improve the performance, you must conduct corresponding heat treatment on the rails of different materials. This is a good way to improve the performance of the rails.There are mainly three types of steel for our rails. One is carbon rail steel, that is, there are no alloy elements in the steel. This is ordinary rail steel with the lowest production process requirements and the cheapest price.The second is micro-alloyed rail steel, that is, a small amount of alloying elements, such as V, Nb, Ti, etc., are added to the steel.The last type is low alloy rail steel.The amount of alloy added is much more!

In order to greatly improve performance, I estimate that the extremely cold steel rails this time will be mainly low-alloy steel rails!

[Hot rolling workshop worker. Wine looking up at the starry sky]: What I care about is the strength of steel!As we all know, there are several heat treatment methods for rails, such as rolling and cooling the rails before reheating, and using the waste heat of rolling for heat treatment, which can increase the strength of the rails to 780Mpa, 880Mpa, 980Mpa, 1080Mpa, or even higher strength!

If the strength of the steel rail is increased to a high level, it becomes a wear-resistant rail or a high-strength rail, and its mechanical properties are guaranteed. This steel will be very durable. Fuck!

Sakura Country.

The intelligence department specially set up for Dragon Kingdom sent a message a few minutes ago.

Saito just looked dignified.

"Dragon Kingdom wants to manufacture extremely cold steel rails? Do they also want to build trains?"

Nearly a hundred scientists in the audience suddenly had a bottom line in their hearts.

Now that the Dragon Kingdom has done this, then...does it mean that their own country's plan is feasible?

Saito said confidently: "Everyone, even Longguo is starting to forge extremely cold steel, which shows that our plan to train around the country is feasible!" He took out a plan.

This is the solution that hundreds of scientists came up with after discussing for a day, which they think is the best solution to this disaster!

"The Extreme Cold Train Project Around the Cherry Blossom Country"

"Everyone, this is a huge project!"

"Dragon Kingdom chose the underground city because they are extremely rich in chemical energy and have a lot of land. Most of the areas are located outside the plate boundary."

"In Sakura Country, steel production is insufficient, and there is a lack of energy in all aspects. Most importantly, our land passes through the junction of plates, which means that we have a high probability of earthquakes!"

"And once an earthquake occurs, the dungeon that was built so hard will collapse!"

"So, we came up with the "Crystal Cold Train Plan around the Cherry Blossom Country"!"

"Thanks to our country's rich volcanic and hot spring resources, we may be able to continue to survive on the surface. This round-the-country train will connect most parts of Sakura Country!"

"We can even live inside this train!"

The prime minister stood up, looked at the idea, and asked: "Can this train really survive the blue star after the sun goes out?"

Saito said confidently: "Of course!"

"After the sun goes out, there will be not only extreme cold, but also strong winds, blizzards, etc. Extreme weather and climate will be very common and even become a daily routine. Can this train really withstand it?" the Prime Minister questioned.Saito said: "As long as the cold resistance, strength, impact toughness, etc. of the train are enhanced, it can be defended!"

The Prime Minister nodded and acquiesced to the plan.

10 minutes later, a message spread throughout Sakura Country.

[Announcement from the special disaster department of Sakura Country: Our country will build a train connecting the whole country to resist the doomsday.Citizens are invited to actively participate in disaster-resisting construction. 】

Netizens in Sakura Country were excited.

"Finally...is it finally our country's turn! The Dragon Kingdom has been started for so long, but we haven't moved for so long, I'm about to die of anxiety!"

"Special disaster department? Could it be... the end is real!"

"It must be true, the country is starting to prepare for this doomsday!"

"A train that connects the whole country? Yoshi, this is so cool!"

"Our train is much better than the dungeon in Dragon Kingdom! They can only hide underground like mice, and we can still look at our beautiful East Golden Pagoda and Sky Tree on the frozen blue star!" "Sakura Long live the country!"

Longguo, the Dangerous Information Bureau building.

Standing in front of the world map, Xu Qiu silently drew a circle for Sakura Country.

This is the second country that has entered a disaster-resistant state besides the Dragon Country.

He smiled.

When the prediction of the falling meteorite comes true, I am afraid that a large number of countries around the world will announce their future countermeasures at the same time!

What creative countermeasures will other countries come up with?

In addition, Xu Qiu was very curious. The Cherry Blossom Country did not have a differential engine, so their train around the country lacked a control core.

Do they want to calculate the huge data by hand and use human power to control the start and running of the entire train?

How does Sakura Country solve the problem of the lack of extremely cold computers?

"Director, the extreme cold steel plans from various places have been sent."

Lu Guangyuan came over with a thick stack of materials, and Zou Baitao followed behind.

At the same time, two engineers from the Capital Iron and Steel Group, Wo Chengping and He Yude, also came.

After Capital Iron and Steel Group released the notice, within an hour, tens of thousands of proposals were submitted across the country.

Tens of thousands of proposals were reviewed by Xu Fu, Ji Chengping, high-speed railway engineers, and engineers from Capital Iron and Steel Group and Qinggang Iron and Steel Group. Only a few dozen with practical significance were sent up.

"Director Xu!"

Wo Chengwen and He Yude saluted at the same time.

They knew that the man who held the highest authority in the crisis bureau was very young, but when they actually faced Xu Qiu, they were still shocked.

Those eyes contained wisdom, as well as the calmness of not changing his face before the landslide!

"You two have worked hard."

Xu Qiu returned the gift with deep eyes, and said, "Let me briefly introduce the plan that you think is meaningful."

Wo Chengwen made a gesture: "Please, Mr. He!"

He Yude didn't refuse, and said quietly:

"Director Xu, we have screened out several rail crafts."

"The first is the common bridge pearlitic steel rail. This kind of steel rail has alloy elements added, and the highest strength can reach 1300Mpao. Some engineers have proposed that the density of the cementite phase in the pearlite sheet can be increased to improve wear resistance.

At the same time, increasing the thickness of the FE3C phase and the accumulation of the FE3C phase left by the iron lock body stripped from the surface of the rail head under rolling contact in the pearlite sheet can improve the cold resistance of the hypereutectoid steel! "

"This kind of steel has welding performance equivalent to or even superior to that of heat-treated eutectoid steel rails! Moreover, its wear resistance is 20.00% higher than that of ordinary steel rails, and its cold resistance is directly tripled. Stay resilient!"

Xu Qiu shook his head

"The anti-fatigue performance of the steel rails passing through the common bridge cannot keep up with the weight of the ice layer and the driving pressure of nuclear-powered trains."

"next."

He Yude's eyes froze, showing disbelief.

Nuclear...nuclear powered trains? !

It turns out that the country is going to lay nuclear power trains! !

His wrinkled face showed excitement...

This old man devoted himself to the steel development of the motherland. His greatest wish is to scatter his ashes in the mountains and rivers of the motherland and coexist with the motherland.

However, when the end of the sun comes, this easy wish becomes a luxury that can never be realized.

But at this moment, his wish revived again.

If there is a nuclear-powered train... Then, does it mean that he can take that train and see the great rivers and mountains of the motherland and the frozen Great Wall before he dies!

He Yude suppressed his excitement, he did not forget the present task.

"There is another one, called anti-damage rail!"

"This kind of heat-treated steel rail, by adjusting the cooling rate during heat treatment, treats the tread surface and rail top angle of the rail to different hardnesses. Under the action of impact load, the tread surface with softer hardness will show more wear!"

"And once the wear rate of the tread increases, this part of the harmful fatigue cracks can be 'wear' away naturally, and will not expand!"

"This kind of rail has a strong ability to resist damage. Faced with the same pressure and load, other rails may crack, but this kind of rail will only have cracks, and the cracks will not affect the operation of the train!" "Next One." Xu Qiu said lightly.

"Martensitic steel rail." He Yude had long been prepared to be denied many times.

If it was so easy to meet the requirements, they wouldn't be soliciting proposals across the country.

"The hardness of martensitic steel can reach 445HB, and its toughness is very, very strong. Basically, it can be called the existence with the highest toughness of existing steel, and it definitely meets your standard for impact toughness."
