After "**s" arranged the preparations for the "Asian Crane Machinery Equipment Exhibition", Zhao Guoyang and Mu Yiyi rushed back to "Xingtai International".

Because the department's railway steel plan has been taken from the leader Jia of the Ministry of Railways, Zhao Guoyang naturally has to go to the research institute to confirm the progress of "high-carbon and low-alloy rails".

When Zhao Guoyang rushed to the "Shipbuilding Industry-Special Materials" Research Institute, he was delighted to find that the "high-carbon and low-alloy rails" developed by his research institute have expanded from the original two models of 38 and 43 kg/m to 50, 60 and 70 kg/m to three higher strength rails.

Such a comprehensive category of railway steel is already sufficient to meet the current domestic railway construction needs.

Of course, the materials of this "high-carbon and low-alloy rail" are usually u71mn or 50mn.

Of course, there is no problem with this kind of heavy material used on ordinary railways. But if it is used on high-speed railways, it is not suitable.

Due to the memory of the previous life, Zhao Guoyang is very clear about the composition of rail materials required for high-speed light rails.

55q or q235b with specifications of 6-30kg/m is the best choice for high-speed light rail.

However, the stability of materials such as 55q and q235b is difficult to guarantee, especially when used on rails that do not have any mistakes, which is even more difficult.

With the production level of domestic steel companies, there is currently no company that can ensure the stability of these two materials.

Therefore, in a short period of time, China's EMU and high-speed rail projects have no way to test them.

In this regard, Zhao Guoyang asked his own research institute members to set up a group - the "High-speed Railway Rail Research Group", which specializes in the research of high-strength low-alloy rails.

As long as there is a stable material output, it will no longer be a dream to develop high-speed trains in China.

There is no major breakthrough in this technology at present, but if Zhao Guoyang grasps the general direction, success will be a matter of time sooner or later.

After wandering around the institute, he chatted with Yuan Qinghua, who was in charge of the "High-speed Railway Rail" project. Zhao Guoyang slowly came out of the institute this time.

When Zhao Guoyang inspected the Institute, Mu Yiyi was always with him.

After Mr. Zhao left the institute's door, the assistant president hesitated for a moment, and then said in confusion: "Mr. Zhao, I don't understand this 'high-speed railway rail project'..."

Zhao Guoyang was calculating in his heart how long it would take for the Huaxia High-speed Railway to be established. At this time, he was stunned when he heard Mu Yiyi's words.

Turning his head to look at the other party, Zhao Guoyang gently stretched out his hand and signaled, "Yiyi, there is no one else now. If you have anything you don't understand, just say it."

Although Zhao Guoyang's words did not mean anything else, Mu Yiyi felt something strange.

She asked with a blushing face, "Mr. Zhao, I think it's not known when the high-speed railway project in our country will be implemented. Is it too early for you to spend so much money to study the rail material needed for high-speed railways?"

"Actually, our China steel smelting technology has been improving. Maybe in two or three years, some domestic steel companies have developed this kind of steel. Why do we have to work hard to get it?"

Mu Yiyi's words naturally consider the return on investment of "Xingtai International", which seems to make sense.

After hearing her inquiry, Zhao Guoyang nodded in praise and said with relief: "Yiyi, your ability to think of this means that you have already had your own ideas about how the company can achieve balance of revenue and expenditure. This is a good sign."

"Under normal circumstances, a research department is really a waste of energy and money when studying a technology that cannot be used in a short period of time. However, when it comes to the research on 'high-speed railway rail', I think it is worth the investment."

Zhao Guoyang said, explaining: "First of all, the Ministry of Railways should have allocated more than 10 million yuan to our research institute as early as last year to the research on new rail materials."

"Although we haven't made much money after we have studied these results, we have calculated that we haven't made much money. But at least, we haven't lost it, right?"

Hearing this, Mu Yiyi was slightly stunned and nodded slowly.

Zhao Guoyang paused for a moment and then started to speak: "Secondly, the purpose of our research on this 'high-speed railway rail' was not to look at the present, but to the future."

"High-speed railways are a trend in the future development of the world's railways. Our country has always been the world's most recent railway operation speed, only slightly stronger than the neighboring countries' A-San. This is definitely a major obstacle to economic development for our country with such a large area and a large population."

"If we want to connect our China from south to north and from east to west, the development of high-speed railways is essential."

Listening to Zhao Guoyang's words, Mu Yiyi's eyes became brighter the more she listened.

After Mr. Zhao's explanation, she already knew the problem.

Obviously, it is of far-reaching significance for Zhao Guoyang to launch the project of "high-speed railway rail materials" in his research institute.

Zhao Guoyang did not pay attention to the enthusiasm in Mu Yiyi's eyes. He touched his nose and continued: "Based on some of my previous research on the island country's 'Shinkansen' and France's 'tgv', developing high-speed railways is actually far from as difficult as we imagined."

"As long as objective conditions allow, China can fully model the high-speed railway model of these two countries within three to five years and build its own high-speed railway system!"

"What? With such technical support in China, we can build our own high-speed railway network in such a short time?"

Hearing this, Mu Yiyi's mouth opened her mouth, looking disbelief.

Seeing her stupid look, Zhao Guoyang shrugged disregardably: "This is really not difficult. The biggest advantage of the French high-speed railway - TGV is that it has the technological leadership in the field of traditional wheel and rail."

"In terms of this technology, there are actually some experts and scholars in our country who have profound attainments."

Zhao Guoyang said confidently: "As long as there is enough technical support, it should not be difficult for me to come up with technology that is not inferior to France's TGV within one or two years!"

Zhao Guoyang's words made Mu Yiyi stunned.

She covered her mouth with her hands, and was stunned for a while before saying, "Mr. Zhao, have you mentioned this to the leaders of the Ministry of Railways? What is their attitude?"

Zhao Guoyang said "hum" and said calmly: "I haven't discussed the high-speed railway matters with the leader Jia of the Ministry of Railways yet. However, I mentioned it to Mr. Li."

"Of course, when I mentioned this, I also told Mr. Li about the difficulties. At this stage, the biggest problem we want to develop high-speed railways is, in addition to the basic technologies of high-speed railways, the complexity of our domestic terrain and climate."

Zhao Guoyang said with emotion: "Yiyi, you should know that because of the huge area of ​​China, the complexity of road conditions across the country is far greater than that of France and the island countries."

"For example, if our high-speed train is built in extremely complex terrain and climates such as the Loess Plateau, the Northwest region, and the Qinling Mountains, is it the same as building on a plain?"

After hearing this, Mu Yiyi fell into deep thought.

After a while, she blinked her eyes and nodded and responded: "Yes! The northwest and southwest regions of China are really uncountable. In addition, the vast rivers and rivers like the Yangtze River and the Yellow River are standing in front of them. With such a complex terrain, there is probably no country in the world without them!"

Zhao Guoyang said "hum" and echoed: "That's right, the problem lies here! Take the mountainous area as an example. If the train wants to pass, it must open a tunnel."

Upon hearing this, Mu Yiyi nodded repeatedly, expressing her agreement.

Zhao Guoyang continued: "Trains with normal speeds below 70 kilometers per hour do not have too high requirements for these tunnels. But on high-speed trains, this is another concept!"

"You must know that if a train enters a tunnel under high speed, the pressure it has to bear may be several times that of a low-speed train. Similarly, the train also needs to bear huge tension when leaving the tunnel."

"However, in the western part of China, loess land accounts for more than half. When trains pass through the tunnel, the weakness of loess land will cause great trouble..."

Listening to Zhao Guoyang's in-depth analysis, Mu Yiyi's face showed a serious look.

Zhao Guoyang sighed softly and then said, "Precisely because such problems cannot be solved, I have not yet improved the speed of railways to Mr. Li and the leaders of the Ministry of Railways."

Speaking of this, Zhao Guoyang changed the subject: "However, not mentioning this does not mean we don't need to prepare."

"Our research institute is now starting to study the technology of 'high-speed railway rail materials', which will definitely have very positive significance for our country's high-speed railway projects in the future."

"From our 'Xingtai International Foreign Trade Company's own perspective, once this new material is developed and if the high-speed railway project is really launched in the future, our company's technological leadership will be magnified to the extreme."

"Even within ten or twenty years, it is difficult for a company to compete with us in this technology."

Zhao Guoyang's judgment did not have any exaggeration.

In fact, with the current research results of the research institute under his command, it is already far ahead of other domestic steel companies.

If this continues to develop, within a year, the "Xingtai International" research institute will become the leader of the "high-speed railway rail materials" in the entire China.
