This is a document bag, and judging by the thickness, there should be dozens of pages of documents inside.

Chang Jinlin's face was full of doubts, and he didn't understand for the time being, how when it came to the research and development progress of the EMU, Tang Fei would give himself such a document bag first.

What's inside?

Tang Fei smiled and reminded: "Lao Chang, you open him first, take a look at the things inside, I think it can bring you a huge surprise." ”

"Oh. ”

Chang Jinlin Yiyan opened the document bag, pulled out the contents of the contents, and the first thing he saw was that this was a beautifully bound and beautifully printed introduction material.

On the cover of the information, there are not only the words "JF200A EMU Detailed Introduction", but also a very eye-catching picture, which is a color picture of an EMU, with a bullet-shaped front and a streamlined body, with white as the main color, which looks very beautiful!

This is the introduction material of the JF200A EMU!

Chang Jinlin, who reacted, was suddenly overjoyed, and his heart was very excited. I really didn't think that Tang Fei would give himself such a huge surprise.

This is the introduction of the JF200A EMU, and there are dozens of pages, which must be very detailed. The JF200A EMU will also unveil its mystery in front of Chang Jinlin for the first time.

Holding back the excitement in his heart, Chang Jinlin flipped through the pages first, and after only looking at a few pages, he couldn't hold back any longer, and exclaimed, "Brother, is this the EMU you are developing? It's unbelievable!"

Yes, if you don't see this introduction with your own eyes, who would believe that the EMU that Jiuzhou Industry is responsible for research and development will be so advanced and so outstanding!

Chang Jinlin is not a layman, he has worked in the Red Star Factory for so many years, and has been talking to electric locomotives for so many years, even in the field of EMUs, he should be regarded as an expert, and he fully knows the basic situation of various types of EMUs in the world.

Compared with any type of EMU in the world and JF200A EMU, it seems to be a little worse. In front of you is definitely the world's most advanced 200-kilometer class EMU.

Tang Fei took Chang Jinlin's expression in his eyes, smiled happily, and said affirmatively: "That's right, this is the EMU we are currently developing!"

Chang Jinlin took a deep breath, tried to calm his heart, and asked: "Brother, tell me, how sure are you that such an advanced EMU can be successfully developed, and how long does the research and development cycle take?"

These are the things he needs to know, and they are also one of the main purposes of coming down from the capital this time.

The leaders above knew that Chang Jinlin's relationship with the Red Star Factory was extraordinary, and they also knew that he seemed to have a good personal relationship with Tang Fei.

Even though he was only a vice president in charge of logistics, he was still given such a task, and he came down to investigate and understand the development of the EMU.

He looked at the preparation of the Hongxing Plant for the trial production of EMUs, the construction of the Hexi Plant, and now the introduction of EMUs.

At this moment, Chang Jinlin looked at Tang Fei with hope, and thought in his heart, there must be a great certainty that the research and development will be successful, the cycle must not be too long, and about a year is the best.

He heard Xie Zhenhua say that it is estimated that in a few months, the design of the JF200A EMU will be preliminarily completed, but Chang Jinlin does not dare to place such great hopes on it, and it will be very remarkable and very good to complete the comprehensive design in about a year.

Obviously, Tang Fei had already thought about it, and he didn't want to delay it for too long, so he said with a straight face: "Often, we are at least eight or ninety percent sure that the JF200A EMU will be successfully developed." ”

Eight, ninety percent sure!

Doesn't that mean that this is basically a sure thing, and it won't run at all, and Jiuzhou Industry will definitely develop the EMU.

Chang Jinlin was a little excited in his heart, and hurriedly asked, "Then how long will it take to complete the front design?"

This is what he is most concerned about, and in his opinion, the sooner the comprehensive design is completed, the sooner the first EMU will be trial-produced, the better.

The high-level are paying attention to it, and the leaders specially sent him down, just to understand the research and development progress of Jiuzhou industry, and the leaders also want to take a reassuring pill.

As long as you take a reassuring pill first, many decision-making matters can be decided, such as negotiations with foreign EMU companies, not suspended, but can be put on hold indefinitely.

We can develop EMUs in China, and they are still EMUs with very good performance and advanced EMUs, so there is no need to spend a lot of money to introduce EMU manufacturing technology from abroad.

Chang Jinlin looked at Tang Fei and waited for Tang Fei to answer hopefully.

Tang Fei just thought about it for a while, and then said seriously: "In about two or three months, we can complete the comprehensive design, and then start the process output, and also start the production and manufacturing of various parts of the EMU, the procurement of accessories, and so on." ”

It only takes two or three months, and it doesn't take a year at all!

Chang Jinlin thought he had misheard, "Brother, is it really only two or three months, not one or two years?"

Tang Fei said confidently: "Two or three months is enough." ”

Of course, it is enough, in fact, the JF200A EMU has already been successfully developed, the system is produced, not only has detailed design data, but also has a complete set of production process data, as long as Tang Fei is willing, you can start the production and manufacturing of various parts now.

In the next two or three months, the main thing is to make my technical team better digest and understand the technology of JF200A EMU.

The technicians have thoroughly understood the technology, and the follow-up trial production will definitely be much smoother, which is called sharpening the knife and not cutting wood.

It's really only two or three months, Chang Jinlin was pleasantly surprised, gave a thumbs up to this Tang Fei, full of praise, and happily looked through this introduction information.

Tang Fei didn't disturb him, he waited quietly beside him, and after about half an hour, Chang Jinlin basically finished reading the introduction of the JF200A EMU.

This information is really good, not only has a detailed text description, but also introduces the situation of the EMU in an all-round way, such as which advanced technologies are used, what are the technical advantages, how about the comprehensive performance, how about the service life, how about the maintenance and so on.

Illustrated and illustrated, there are a large number of color pictures, not only the appearance of the EMU pictures, but also the interior of the EMU pictures, from the pictures can be seen, the EMU is very beautiful, beautiful, fashionable, giving people a very friendly and comfortable feeling.

There are also a large number of parameters, all aspects of the parameters are basically there, very complete, very comprehensive, from these parameters can also be seen, the EMU is very advanced, the performance is very good.

After looking through it roughly, Chang Jinlin closed it carefully, "Brother, can you bring me back this introduction material?"

Tang Fei said briskly: "Of course, I have prepared several copies for you, and I will give them all to you later, so that the leaders above can also know about our JF200A EMU." ”

"Really, there are several such introductions, that's great!" Chang Jinlin was very happy.

He carefully put away this introduction material, as if it were not a piece of information, but a peerless treasure.

After collecting the introduction materials, Chang Jinlin said: "For the research and development of EMUs, I am completely relieved, as long as I wait patiently for your good news, I came down from the capital this time, and the first thing." ”

Tang Fei looked at Chang Jinlin.

Chang Jinlin came down from the capital, in addition to understanding the progress of the development of the EMU and checking the cooperation between Jiuzhou Industry and Hongxing Factory, there is another very important thing, which is also related to Jiuzhou Industrial Group.

…….

North, an electric locomotive factory.

This is a well-known old factory in the domestic electric locomotive industry, which has a history of several decades, starting from the production and manufacture of steam-powered trains, then to diesel locomotives, and then to the current electric locomotives.

Now, they are ready to start producing metro locomotives.

The manufacturing technology of subway locomotives was imported from abroad, and after paying a lot of price, the technology was finally introduced.

The first row of sample car parts has arrived from abroad, has been many days ago into the factory assembly workshop, a lot of parts are placed next to the assembly bench not far away, a lot of technicians, assembly workers, etc., from time to time there to visit, learn, understand these accessories.

In a few days, the assembly will be carried out.

On the next pedestal, the first subway locomotive has entered the car, and the car body, the undercarriage, the bogie of the locomotive, etc., are all transported back by the factory from the foreign subway locomotive manufacturing enterprise in accordance with the technical agreement.

As the chief engineer and deputy general manager of the plant, Nie Qingshan basically stays at the production site of the assembly workshop these days, focusing on the assembly of the first subway locomotive.

They are one of the two subway manufacturing enterprises supported by China and selected from several domestic more powerful electric locomotive companies to manufacture subway locomotives.

Nie Qingshan felt that the burden on his body was very heavy.

The pressure was unprecedented, and he didn't dare to slack off in the slightest.

He also personally inspected these locomotive parts shipped from abroad, which are basically the core parts of subway locomotives.

A competent technician walked to Nie Qingshan's side and reminded softly: "Mr. Nie, we have carefully checked, those IGBTs are all third-generation products. ”

Hearing this, Nie Qingshan's face changed slightly.

At present, whether in the domestic market or in the international market, the best and most advanced IGBT products are the fifth generation, which are mainly manufactured by Jiuzhou Industrial Group.

The subway locomotive is also a kind of electric locomotive, and a large number of IGBTs are required on each subway locomotive to realize the current connection and cut-off, so as to realize the efficient and rapid conversion of electric energy.

It was only the third-generation IGBT product, and Nie Qingshan had an ominous premonition.

This kind of hunch is not new now, many days ago, after these parts arrived, Nie Qingshan felt that he might have been fooled.

The subway locomotive technology imported from abroad at great expense is not very advanced, and should be generalized abroad, or even slightly backward.

Now, things seem to have been confirmed.
