At Kyushu Industrial Group, the trial production of various parts of the EMU is proceeding very smoothly. Because the production process is from the system, very scientific, very detailed, as long as it is manufactured in accordance with the process regulations, in strict accordance with the parameters and process step requirements, the parts produced basically do not have any quality problems, basically belong to the excellent products

The first manufacturing can make excellent products, which is basically unimaginable in other manufacturing enterprises, but in Jiuzhou Industrial Group, the majority of employees have long been accustomed to it, and feel that this is very normal. If the parts produced are substandard, or there are quality problems, everyone will think it is strange.

The trial production of parts of Jiuzhou Industrial Group EMU is very smooth, whether it is the operation control system or the braking system or the power system, these key technical difficulties and production difficulties are very high in the trial production of Jiuzhou Industrial Group.

The trial production of his own parts was relatively smooth, Tang Fei was a lot more relieved, and began to pay attention to the trial production of parts in the Red Star Factory.

So, he went to the Red Star Factory today, and walked into the parts processing and manufacturing workshop of the Red Star Factory accompanied by Xie Zhenhua. This is the car body workshop, which is engaged in the production of car bodies including DJ4 electric locomotives and Shaoshan series electric locomotives.

Of course, there is also the production and manufacturing of EMU car bodies.

At the production site, the first section of the car body can be seen welding. It is different from the body material of other electric locomotives, whether it is the body of the DJ4 electric locomotive or the Shaoshan series of electric locomotives, their materials are generally various steels.

The body of the EMU is mainly made of light metal, such as aluminum alloy as the main material, and composite materials are also used, which can reduce the weight of the body to the greatest extent and ensure the structural strength of the body. Tang Fei saw that the welding of the car body was being carried out at the production site, which is the welding of aluminum alloy, which is not a new thing in the aluminum alloy welding of Kyushu Industrial Group, and it is very mature in the process, such as the body of the subway locomotive is mainly aluminum alloy.

Obviously, the Red Star Factory has a relative lack of experience in this aspect, and they are basically crossing the river by feeling the stones, and they are more worried.

No, Tang Fei saw that there were not many car body welds here at the production site, and the progress was slow, and there seemed to be a few technicians and a few welding workers, who seemed to be discussing some problems in welding?

I didn't see the welding of the second EMU body at the production site, this should be the welding of the first train body, this progress is really slow, no wonder Tang Fei's face changed slightly, he didn't expect that the progress of the Red Star Factory was much slower than he imagined.

In order to verify his guess, Tang Fei looked at Xie Zhenghua and asked slowly, "Old Xie, is this the welding of your first car body?"

Xie Zhenhua was a little embarrassed, and said embarrassedly: "This is the first section of car body welding, and it has not been a few days since the beginning of welding." ”

What! slower than you think.

Tang Fei's face changed slightly, and then he walked towards the station where the car body was welded.

When I got closer, I finally knew what the technicians and welders were discussing? It turned out to be discussing how to weld. Isn't there a detailed information on the welding process that is readily available?

Tang Fei didn't speak, wanting to hear what they were saying and how they were discussing.

After listening for a while, I finally knew that the welding of the car body was very complicated, and there were hundreds of large and small sheets, and there were countless welds. Once the welding deformation occurs, it will not only affect the welding size, but also affect the welding quality of the entire car body.

It is no wonder that these technicians and welding workers are timid, shrinking their hands and feet, and they can't let go of their worries at all. If it were in Jiuzhou Industrial Group, such a thing would not have happened at all.

Whether it is a production worker or an ordinary technician, we have a lot of trust in the production process materials, and will have no scruples, and there is no doubt that the processing and production will be carried out in strict accordance with the process regulations, and there will be no deviation.

In terms of the Red Star Factory, it is not completely like this, and their technicians are also worried. No, after welding a few welds, the dimensions are being measured there, and then the next step is being discussed. In the end, it is in accordance with the parameters and methods required in the process regulations, or it is your own originality. Use the parameters and methods that you think are reasonable.

Seeing that they were actually discussing such a problem, Tang Fei shook his head and smiled bitterly, and said to Xie Zhenhua: "Old Xie, do you often have such a situation between the production and trial production process of EMUs?"

Xie Zhenhua nodded and admitted: "Yes, it is often the case, although we said that we can let go of our hands and feet, and require the production and processing of parts and components in strict accordance with the process requirements, but there are still some workers and technicians who feel that they are experienced, and always find their own way to process according to the methods and parameters that they think are reasonable." ”

Tang Fei said anxiously: "This is not good! This will not only cause quality problems, but also cause delays in the production schedule, causing production to be very slow, affecting the production process of our first train." ”

Xie Zhenhua asked: "Brother, are you so confident in your process data, as long as you follow the parameters and steps of the process data, there will be no problems?"

Tang Fei affirmed: "As long as the processing is carried out in strict accordance with the process information provided by us, there will be absolutely no problems, and you can rest assured of this." ”

Seeing that Tang Fei said it so deadly, he remembered that he had visited Kyushu Industrial Company many times, and saw that their workers were all produced and manufactured in strict accordance with the process materials, so Xie Zhenghua had secretly made up his mind in his heart and said in front of Tang Fei.

"Brother, since there is no problem with the process information you provide, then I will hold another meeting, focusing on the production trial production of parts in strict accordance with the parameters and steps of the process regulations. ”

Tang Fei said: "It should have been like this a long time ago, only in this way can we ensure the smooth progress of production and trial production, I tell you now, your progress is much slower than ours, you must catch up." ”

Xie Zhenhua said: "Okay, we will redouble our efforts to catch up as soon as possible, and we will also strictly follow the process data to carry out the production trial production of parts, and there will be no more such a situation." ”

Seeing this, Tang Fei was relieved in his heart.

Accompanied by Xie Zhenhua, I watched the production trial production of many parts, such as the welding of the car body, the manufacture of bogies, and the production and manufacturing of car body end parts

In the assembly workshop of Hongxing Factory, Xie Zhenhua said that the assembly station of the first EMU has been vacant, and as long as all the parts are manufactured, the vehicle assembly of the first train can be carried out.

To tell the truth, the relevant work of the Red Star Factory is still very good, if you let go of your hands and feet, the speed will catch up, and the assembly of the first train should start around the National Day.

The whole assembly of the first train, this is really worth looking forward to!.

During the visit to the Hongxing Factory, Tang Fei also asked Xie Zhenhua how the production license and market access procedures for the EMU were handled.

This is the matter that the Red Star Factory is responsible for, Xie Zhenhua told Tang Fei that it has passed the high-level approval of Huaxia NC Group, and the relevant information has been submitted to the higher departments, and it is estimated that in about a month or two, there should be news.

Tang Fei nodded, it will take another month or two to obtain the production license and market access of the EMU, which is still ideal.

Tang Fei advised: "Lao Xie, you should try to pay close attention to the handling of these procedures, and try to handle them as soon as possible." ”

Xie Zhenhua said: "Okay, I'm going to go to the capital again in a few days, I will personally pay attention to these things, and also go to the higher departments to run around." ”

The EMU has completed a comprehensive design, the relevant parts have started to be fully purchased, and the surrounding suppliers are also manufacturing many parts.

According to the current progress, around the National Day, the assembly of the first EMU will begin, that is to say, before and after the National Day, the first EMU will begin to enter the car.

Everything is basically going according to plan, if there is a deviation from the plan, it is that the trial production of parts of the Red Star Plant is a little behind. As Tang Fei reminded that the production trial production must be carried out in strict accordance with the process data, the Red Star Factory held a conference and emphasized the process discipline, and their progress should catch up.

These days, Tang Fei's focus is on the production trial production of EMUs, and he basically goes to the production site every day to have a look, and sees that everything is going smoothly in the trial production, and he is more relieved.

Today, Tang Fei received a call from Chen Guihong.

On the phone, Chen Guihong was obviously in a good mood, and said loudly: "Brother, you are busy with the trial production of your EMU in Qingjiang City!." ”

Tang Fei said: "That's right, our first EMU has completed the comprehensive design, and the production trial production of parts has started first, and it will enter the train around the National Day." ”

Chen Guihong said: "Congratulations, this is the first EMU in China, which is of great significance, the last time I went back to the capital, I heard the old man also specially mention your EMU." ”

Even the old man of Chen Guihong's family was paying attention to the EMU, Tang Fei was surprised at first, and then he felt deeply proud, and the senior management was paying attention!

After the two chatted for a while, Chen Guihong said: "Brother, I will go back to the capital tomorrow, are you free, how about we get together in the capital?"

Getting together in the capital?

Why not in Shenhai City or Qingjiang City, is there any deep meaning? Tang Fei thought so in his heart, and immediately agreed: "Okay, then I will come to the capital in two days, and we will have a good get-together." ”

Chen Guihong looked very happy and said loudly: "Then it's decided, I'll wait for you in the capital." ”

Two days later.

Tang Fei is ready to leave for the capital, in addition to getting together with Chen Guihong and exchanging brotherly feelings, he also wants to see what the deep meaning of Chen Guihong's advocacy of getting together in the capital is.

This time he went to the capital, Tang Fei only brought two people, the first was his driver and bodyguard Xu Guangming, and the second was his girlfriend Li Xueyan.

Today's third watch, the third watch is completed, thank you for your support!
