I! Pretending to Be Reborn, Director of Doomsday Hoax

After hearing these speeches, Zou Botao and others were extremely excited.

But seeing that Xu Qiu had closed his eyes, he didn't dare to disturb him any more, and quietly left the conference room with agitation.

A brand new production line.

The process of forging the steel rail emerged in Xu Qiu's mind.

In fact, with the development of high-speed and heavy-duty railway transportation, the quality requirements for steel rails are also getting higher and higher.

Moreover, as the speed of the vehicle gradually increases, the life of the rails becomes shorter and shorter.

Under multiple factors, the inherent defects of traditional crafts are becoming more and more serious.

For example, problems such as asymmetry in geometric dimensions, excessive tolerance of rail height, bottom width, etc., scratches and decarburization on the surface, straightness of appearance and blind spots in internal quality inspection, etc., all seriously hinder the improvement of rail quality.

The rails produced by the traditional die-casting process can no longer meet the requirements of high-speed railways on the dimensional accuracy, internal quality and mechanical properties of the rails.

Therefore, relevant departments and enterprises in various countries are improving and gradually adopting forging and rolling methods to replace the casting process.

However, in the face of extremely cold steel rails, the advanced forging and rolling techniques that have been developed today are no longer enough to support the production of this cross-age material!

It's like, now Wo Chengwen, He Yude and others have developed a spacecraft that can fly into space, but the current energy sources are only firewood and coal.

And what Xu Qiu wants to provide them now is nuclear energy.

Nuclear power capable of supporting this delicate spacecraft, flying into space!

From firewood to coal, from coal to oil, and then to nuclear energy, it took humans thousands of years to accomplish all of this.

How could Xu Qiu come up with a new rolling production line?

"Or, can you try the rolling process of special section rails?"

Xu Qiu was not willing to give up, he was thinking.

But soon he vetoed it. The rolling process of the special cross-section rails had the phenomenon of lack of meat in the rail head and folding of the rail waist during the production process.

Moreover, the rolling of special section rails and the design and production of extremely cold rails are almost two completely different directions.

"what can we do about it..…"

"T-shaped large forging free forging method?"

"Elastic bendable point rail technology?"

Xu Qiu closed his eyes tightly and hesitated.

dong dong dong.

Mi's knuckles tapped the rim of the teacup continuously, making a dull sound.

at this time-

A mechanical electronic synthesis sound sounded again.

"Congratulations to the host, the number of countries preparing for the Little Ice Age has exceeded 50.00%!"

"The credibility of your prophecy has increased again, and the fraud effect has increased again!"

"Congratulations, you have received an incentive reward!"

"You have obtained, the extremely cold rail rolling process production line!"

The sound of Xu Qiu knocking on the teacup stopped abruptly.

He listened to the system prompt in a daze, and was pleasantly surprised.

finally come! !

Hey.

His periosteum was shaking crazily, and a lot of knowledge poured into his mind.

A brand-new production line design scheme has already formed in Xu Qiu's mind!

Looking at the perfect, high-dimensional precision production line, Xu Qiu gradually became excited.

Now that he has mastered the master-level knowledge of mechanics, it can be said that few people can be more authoritative than him in the development and manufacture of steel rails.

Therefore, with just one glance, Xu Qiu can see how valuable this production line is and how much wisdom it contains!

This rolling production line adopts a nine-stand layout and adopts many new technologies to meet the production needs of high-dimensional precision rails.

Moreover, on the basis of the transformation of the original most advanced universal rolling mill, the optimization of the whole process was carried out, including the improvement of the whole line including heating, rolling, cooling, straightening, testing and hoisting! It can be said that the steel rails passing through this production line , must be stable and efficient. This will be the world's most

For advanced steel production lines! !

Xu Qiu looked at the design idea of ​​this production line in shock.

In the extremely cold rail rolling production line, the most important point is that it improves the continuous casting process!

In fact, the continuous casting process has been gradually improved in the past 20 years, and has reached a bottleneck period and has been stagnant.

And this process is a crucial part of rail forging.

However, this extremely cold rail rolling production line has geniusly added protective casting to it, which effectively prevents the secondary oxidation of molten steel during casting, greatly reduces the inclusions in the steel, and can also improve the surface quality of the billet.

At the same time, in order to ensure that the extremely cold rails have good surface quality, internal quality, geometric dimension accuracy and appearance straightness, on the basis of continuous casting, the new production line also adds a rail precision casting!

Xu Qiu feels this production line in awe. If humans are allowed to explore it by themselves, this production line may require the most intelligent people in all countries to study carefully for decades...

But now, it is quietly lying in Xu Qiu's mind, waiting to be put into practice and show its grand plans! !

Xu Qiu stood up, with mixed feelings in his heart, and couldn't help saying: "The spacecraft is ready, now, it's time to put nuclear fuel on this thing, and it will fly into the sky..."

July NO.30, [-]:[-] pm.

After Wo Chengwen, He Yude and others sent Xu Qiu a request for assistance, they were still locked in the R&D workshop and production workshop, thinking about countermeasures non-stop.

Although they knew that they had exhausted all methods, Wo Chengwen and others were still unwilling to give up.

It's a matter of attitude!

However, in the R&D workshop, there was still a sense of despondency.

They are so desperate.

A brand-new production line requires an industry, and millions of people accumulate and improve it a little bit before it can be produced.

But now, what troubles them is not the parameters, the ratio of chemical elements, or various defects, but a production line is missing.

"Oh." Someone sighed.

"I think Director Xu may not be able to do anything." Someone had a desolate expression.

"The brand-new rolling production line and gating system are not of the same order of magnitude at all. Director Xu is indeed a genius, even more experienced than us engineers who have studied steel and rails for decades, but he is probably helpless!"

Hearing these words, Wo Chengwen could only sigh continuously.

Indeed, it was too difficult, but besides asking Xu Qiu for help, is there any other way?

He could only encourage: "No matter what the result is, we have to come up with a plan."

"This kind of steel rail is related to the transportation of materials in the dungeon in the future of the Dragon Kingdom, and it is related to all aspects of mechanical manufacturing under the extreme cold..."

"Even if we fail to hand in the paper before the end of the month, we... have to answer this paper as satisfactorily as possible!"

After hearing this, everyone was inspired, and they were all trying to cheer themselves up and continue to work.However, at this moment, Wang Xinke hurried in.

He shouted excitedly: "Comrades, Director Xu is coming again, quickly pack up your appearance and go out to meet Director Xu!!" At this moment, countless eyes looked over, and each pair of eyes was full of hope. and look forward to!

The helicopter landed at the Capital Iron and Steel Group.

This super-large iron and steel plant with an annual output of tens of millions of tons is running rumblingly at the moment, with various reaction furnaces and smelting furnaces in operation, supplying high-quality steel for the construction of underground cities in various places.On the employee square, Wang Xinke, chairman of the Capital Iron and Steel Group, was headed by the older generation of engineers, including Wo Chengwen and He Yude, standing behind, respectfully welcoming the big shots on the helicopter.

"Director Xu!"

"Director Xu is healthy!"

"Welcome Director Xu to visit Shougang again!"

Their shouts were full of excitement and joy, as if they were expecting something.

Xu Qiu had a smile on his face, of course he knew what these little old men were waiting for now.

He waved his hand and said straight to the point: "Go to the R&D workshop, time is precious."

Wo Chengwen, He Yude and others were full of excitement, leading the way and surrounded Xu Qiu to the research and development workshop.

Wang Xinke and Zou Baitao had wry smiles on their faces, mixed with complicated emotions.

"Director Xu, really...is there a way?" Wang Xinke felt unbelievable.

Although the young bureau chief has given too many miracles, can the new rolling production line really be designed casually?

Zou Baitao had never trusted someone so much for a moment. He raised his head and said with emotion: "Since Director Xu is here, he is here to solve the problem, whether it is a new rolling production line or other solutions." As long as he comes, This problem will be solved easily! "

Wang Xinke was in awe, and his eyes were full of admiration and respect when he looked at the young figure in front of him.

"Director Xu, let's get started!"

"Director Xu, we are ready, do you really have a new rolling line?"

"Or is there another solution?"

Wo Chengwen and the others couldn't wait any longer, and as soon as they arrived at the R&D workshop, they began to ask questions in a hurry.This group of calm engineers couldn't hold their breath at this moment.

Xu Qiu didn't change his face, and said calmly:

"This time, I propose a new rolling production line."

boom!

At this moment, Wo Chengwen and the others felt a thunder suddenly ringing in their ears!

This is their most extravagant hope, but also the most impossible thing to achieve!

In fact, for more than 40 years from the end of the [-]th century to the present, the rail production equipment and production lines of domestic iron and steel enterprises have not been updated.

International development has also come to a near standstill.

Except for the intermittent introduction of some new processes every year, such as universal rolling mills, bendable point rails, etc., there is no improvement.

And a brand new rolling production line means... rail rolling may enter a new era!

One of the biggest reasons why rare cars became mainstream means of transportation was the opening of advanced and efficient production lines!

"Director Xu, what you... are telling the truth?!"
