Chapter 460 The Dilemma of Domestic Subway Production

This is a document bag, judging from its thickness, there should be dozens of pages of documents inside.

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

What's inside?

Tang Fei reminded with a smile: "Old Chang, you open it first, take a look at the contents inside, I think it can bring you a huge surprise."

"Oh."

Chang Jinlin Yiyan opened the file bag and took out the contents. The first thing he saw was that it was a beautifully bound and printed introduction.

On the cover of the document, there are not only the words "JF200A EMU detailed introduction", but also a very eye-catching picture. The main color looks very beautiful!

This is the introduction material of JF200A EMU!
Chang Jinlin, who had reacted, suddenly became happy, 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 train, and it has dozens of pages, so it must be very detailed. The JF200A EMU will also unveil its mysterious veil in front of Chang Jinlin for the first time.

Resisting the excitement in his heart, Chang Jinlin first flipped through the pages, and after only flipping through a few pages, he couldn't bear it anymore and exclaimed, "Brother, is this the EMU you are developing? It's unbelievable!"

Yes, if you hadn't seen this introduction with your own eyes, who would have believed that the EMU developed by Jiuzhou Industry would be so advanced and excellent!

Chang Jinlin is not an outsider. He has worked in the Red Star Factory for so many years and has dealt with electric locomotives for so many years. Even in the field of EMUs, he should be regarded as an expert, fully aware of the basic situation of various types of EMUs in the world.

Compared with the JF200A EMU, any type of EMU in the world seems to be a little bit worse.What is in front of you is definitely the most advanced 200-kilometer EMU in the world.

Tang Fei saw Chang Jinlin's expression in his eyes, smiled happily, and said affirmatively: "Yes, 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 many percent of you are sure that you can successfully develop such an advanced EMU, and how long does the development cycle take? "

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

The leaders above knew that Chang Jinlin had an extraordinary relationship with Red Star Factory, and 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 assigned such a task, and he came down to investigate and understand the development of the EMU.

He looked at the preparations for the trial production of the EMUs at the Red Star Factory, the construction of the Hexi factory, and now he saw the introduction materials for the EMUs.

At this moment, Chang Jinlin looked at Tang Fei with hope, and thought in his heart that there must be a high degree of confidence in the success of the research and development, and the cycle must not be too long, and a year or so is best.

He heard from Xie Zhenhua that the design of the JF200A EMU would be preliminarily completed in a few months, but Chang Jinlin did not dare to place such high hopes. It would be great if the overall design could be completed in about a year. , very good.

Obviously, Tang Fei had already thought about it, and he didn't want to procrastinate too long. He said seriously, "Old Chang, we are at least 200% to [-]% sure that we will successfully develop the JF[-]A EMU."

Eighty to ninety percent sure!

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

Chang Jinlin felt a little excited again, and quickly asked: "How long will it take to complete the previous design?"

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

The higher-ups are paying attention, and the leaders even sent him down specially, just to know about the development progress of Jiuzhou Industry, and the leaders also want to have a reassurance.

As long as you take a reassurance first, you can make decisions on many decision-making matters. For example, negotiations with foreign train companies are not suspended, but can be put on hold indefinitely.

We can develop EMUs in our own country, and they are still excellent and advanced EMUs, so there is no need to spend a lot of money to import EMU manufacturing technology from abroad.

Chang Jinlin looked at Tang Fei, waiting hopefully for Tang Fei's answer.

As for Tang Fei, he just thought about it for a while, and then said seriously: "In about two to three months, we will be able to complete the overall design, and then start the process output, and also start the production and manufacturing of various parts and accessories of the EMU. purchases, etc.”

It only takes two or three months, not a year at all!
Chang Jinlin thought he heard it wrong, "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 has been produced. Not only does it have detailed design information, but also a complete set of production process information. As long as Tang Fei is willing, the production of various parts can be started now.

In another two or three months, the main reason is to let my technical team better digest and understand the technology of the JF200A EMU.

If the technicians have a thorough understanding of the technology, the follow-up trial production will definitely be much smoother. This is called sharpening the knife without cutting firewood by mistake.

It really only took two or three months. Chang Jinlin was pleasantly surprised and gave Tang Fei a thumbs up, full of approval, and happily flipped through this introduction.

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

This information is really good. It 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 is the overall performance, how is the service life, how is the maintainability? So wait.

There are a lot of pictures and texts, there are a lot of color pictures, not only the exterior pictures of the EMU, but also the pictures of the interior of the EMU. From the pictures, we can see that the EMU is very beautiful, beautiful and fashionable, giving people a very friendly and comfortable feeling.

There are also a large number of parameters, and there are basically all kinds of parameters, which are very complete and comprehensive. It can also be seen from these parameters that the EMU is very advanced and its performance is very good.

After flipping through it roughly, Chang Jinlin closed it carefully, "Brother, can you take this introduction material back for me?"

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

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

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

After collecting the introduction materials, Chang Jinlin said: "I am completely relieved about the research and development of the EMU, as long as I wait patiently for your good news, I have the first thing to do when I come down from the capital this time. "

Tang Fei looked at Chang Jinlin.

When Chang Jinlin came down from the capital, in addition to learning about the progress of the development of the EMU and checking the cooperation between Jiuzhou Industry and Hongxing Factory, there was another very important matter. This matter was also related to Jiuzhou Industry Group .

.......
In the north, an electric locomotive factory.

This is a well-known old factory in the domestic electric locomotive industry. It has a history of several decades. It started from manufacturing steam-powered trains, then diesel locomotives, and now electric locomotives.

Now, they are ready to start producing subway locomotives again.

The manufacturing technology of the subway locomotive was imported from abroad. After paying a considerable price, the matter of technology introduction was finally negotiated.

The parts of the first prototype car have arrived from abroad, and have entered the assembly workshop of the factory many days ago. Many parts are being placed not far from the assembly bench. There to visit, study, understand these accessories.

In a few days, it will be assembled.

On the platform next to it, the first subway locomotive has already entered the car. The car body, underframe, locomotive bogie, etc., are all transported back from the foreign subway locomotive manufacturer according to the technical agreement. .

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

They are one of the two major subway manufacturing companies supported by the country. They were selected from several relatively powerful electric locomotive companies in China to manufacture subway locomotives.

Nie Qingshan felt that the burden on him was very heavy.

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

The same goes for him, personally inspecting these locomotive parts shipped from abroad, which are basically the core components of subway locomotives.

A technician in charge walked up to Nie Qingshan and reminded softly: "Mr. Nie, we checked carefully. 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 is mainly manufactured by Jiuzhou Industrial Group.

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

It is actually only the third generation of IGBT products, Nie Qingshan has an ominous premonition.

This kind of premonition is not unique now. Many days ago, after these parts arrived, Nie Qingshan felt that he might be fooled.

The subway locomotive technology imported from abroad with great effort and cost is not very advanced, it should be generalized abroad, or even slightly backward.

Now, things seem to be confirmed.

.......
Today is the third update, and the second update will be delivered!
