Within a few minutes, Zeng Qinghai came over, and as soon as he entered Li Tianfeng's office, Zeng Qinghai said, "Boss, are you looking for me?" ”

Li Tianfeng said: "Come, please take a seat." ”

Saying that, Li Tianfeng took out this thick white paper process specification, this is the casting process specification of the third generation of single crystal blades, before the process specification was compiled, Zeng Qinghai was in charge, and Li Tianfeng did not give any guidance.

The process specification was completed, because it was such an important part of the turbine blade, Zeng Qinghai personally sent it over, and asked Li Tianfeng to check it and review it.

This is the unwritten tradition of Tianfeng Technology Company, whether it is in design or technology, some important things are checked by Li Tianfeng, and the design drawings of important parts, Qiu Wenan and Sun Xiaoping will send them to Li Tianfeng for guidance and checking.

Zeng Qinghai usually sent the processing technology regulations of important parts in person, and also asked Li Tianfeng to check and guide them.

In everyone's minds, Li Tianfeng is the supreme god of everyone's technology, the lighthouse in everyone's heart, there is no need to remind, and there is no need to form a text.

Seeing Li Tianfeng holding this thick turbine blade casting process specification, Zeng Qinghai said: "Boss, this is the process specification compiled by us in combination with the most advanced casting and molding technology at present. ”

Li Tianfeng nodded, to be honest, in the eyes of ordinary people, this process specification is good, very good, there is almost nothing wrong, but Li Tianfeng decided to make a big change to the process specification and adopt a very advanced technology.

Li Tianfeng said: "Mr. Zeng, have you heard of the directional solidification casting technology of single crystal blades? ”

Zeng Qinghai nodded and said: "I've heard of it, and I know a little about it, but this kind of technology looks at the world, even if it's the big aero engine giants." They're just getting started. ”

Li Tianfeng said: "What about the world's aero engine giants, our Tianfeng Technology Company will also be the world's aviation industry giants and aviation industry overlords in a few years!" ”

Aviation industry giants!

Overlord of the aviation industry!

Zeng Qinghai's heart was slightly excited, if he could achieve such a journey, he would have no regrets in this life!

Li Tianfeng himself is the same. To achieve such a high goal, I am worthy of my life and a success!

Li Tianfeng took a deep breath, calmed his mood slightly, sorted out his thoughts and said: "Mr. Zeng, our third-generation single crystal turbine blades will use directional solidification casting, which is currently the most advanced technology in the world. ”

Zeng Qinghai said happily: "Mr. Li, you have mastered this technique!" ”

Li Tianfeng said confidently: "Of course, come." Let me tell you about it. ”

After speaking, Li Tianfeng picked up the pen and paper and began to explain this technology carefully with Zeng Qinghai, explaining the technical points very thoroughly, and then the process method, process steps, and process parameters. Make it clear one by one.

A few sheets of A4 white paper, densely written. But the handwriting was neat and organized, and the two of them also completely entered the state, one spoke seriously, and the other listened carefully and unconsciously. More than an hour passed.

Monocrystalline blades represent the highest level of turbine blades in the world today, and have developed to the third generation of monocrystalline blades. The technology of the second generation of monocrystalline blades is not yet mature.

As for the third-generation single crystal blade, the domestic aviation industry has not mastered the national brand enterprises, at most it is only the beginning or contact understanding stage, and Tianfeng Technology Company has undoubtedly come to the forefront.

Especially the directional solidification casting technology just now, which is a very advanced single crystal blade manufacturing technology, using such advanced technology, the pass rate and quality of single crystal blades will be improved by more than a grade.

The casting of single crystal blades is the most widely used in the two processes of "seed crystal method" and "crystal selection method", among which the "crystal selection method" is relatively advanced.

Zeng Qinghai led the compilation of the casting process specification for turbine blades, which uses the more advanced "crystal selection method", and it is also the most advanced "spiral crystal selection method".

I have to say that Zeng Qinghai's process level is still very good, so the advanced "spiral crystal selection method" is compiled into a detailed process specification, and the process steps and process parameters are basically reasonable, which is very rare.

However, in order to obtain a higher quality single crystal turbine blade, Li Tianfeng has to use directional solidification casting technology, which is currently the most advanced single crystal blade production process.

More than an hour later, Li Tianfeng said, "Mr. Zeng, how is it?" Do you get it? ”

Zeng Qinghai slowly closed his eyes, sorted out these things in his mind a little, and then said: "Boss, I basically understand, after listening to your guidance, it seems that a new door has been completely opened in front of me, as if I have entered a new world." ”

Li Tianfeng said: "You take these pages away, take a good look at them, digest them, and if you have any questions, you can come to me again." ”

Zeng Qinghai was like a treasure, carefully put away these pages of A4 paper, and looked at Li Tianfeng with a look of admiration, "Boss, I must sort out and digest it well, if there is anything I don't understand, I will ask for advice again." ”

Li Tianfeng said: "Go ahead!" ”

Looking at Zeng Qinghai and Li Kai's own office, Li Tianfeng thought in his heart that with such an advanced single crystal blade production process, the turbine blades of this turbofan engine must be of high quality, and the service life and performance will surpass the third-generation single crystal blades produced by other aviation companies.

The crux of the matter is that such a new process may have to go through many trial productions, many refinements, and finally success after many times.

Early August.

The weather is the hottest time of the year, and it is also the day when new employees of Tianfeng Technology Company report, with the rapid development of the company, especially the expansion of the second phase of the project, Tianfeng Technology Company has recruited a group of new employees.

Among the more than 1,000 new employees, there are 7 or 800 front-line skilled workers, and nearly half of these hundreds of front-line skilled workers are skilled workers with several years or more than ten years of work experience. The other half are students who have just left college.

These students who will go to the front line as skilled workers, the minimum is also college students, these young workers, Tianfeng Technology Company will be trained as a reserve force, a few years later, this batch of workers will definitely be very outstanding.

In addition to seven or eight hundred front-line skilled workers, there are also five or six hundred college students, masters, and even doctors, and I heard that there are also postdoctoral fellows.

Now Tianfeng Technology Co., Ltd. is also a well-known enterprise in the domestic aviation industry, and the treatment is generally relatively high, and it has become a sweet spot in the job fairs of major universities, and many college students are simply breaking their heads.

Five or six hundred college students, masters, and even doctors, will be the technical personnel of Tianfeng Technology Company, including design, technology, materials and other fields, and some management college students will be trained as grassroots managers.

As the general manager of the human resources department and the director of human resources, Hu Xiao's ability is still very outstanding, and the su zhì of this batch of new employees is very high, that is, among these skilled workers, there are more than double digits of technicians, and there are several senior technicians.

The gate of Tianfeng Technology Company.

A bus stopped on the side of Songzhou Avenue not far from the gate, and a large group of people got off the bus, at least a dozen people, looking like they should all be new employees of Tianfeng Technology Company.

"Wow, look, that's our new company!"

"Yes, it's beautiful, it's so stylish."

"It's the same as the job pitch, no, it's prettier, I like it!"

“……”

This large group of people, when they saw the gate of Tianfeng Technology Company, was amazed, and then, there was a burst of joy and accelerated their pace.

At the door, several security guards stood straight, these are veterans, completely military style, every day, everyone insists on training, the training of security guards, often become a beautiful scenery of Tianfeng Technology Company.

"Wow, our security guard brother has such a standard military posture!"

Everyone was brightening up, exclaiming, and then about to walk towards the factory, a security guard immediately stopped everyone, but knowing that everyone was a new employee who came to report, it was polite, "Everyone here first registers, and then you can enter the company." ”

So formal, but also to register, everyone was slightly stunned, but also happy for the company's such a formal management, one by one to register, and then walked into the factory.

As soon as I entered Tianfeng Technology Company, everyone was shocked, the straight eight-lane factory main road pen to the bottom, looking at it, there was almost no end, what a large factory area.

Next to the main road of the factory, a huge modern factory building hits everyone's eye, and in front of everyone, the magnificent and huge technical center building and modern office building.

"This, this is our company!"

"yes, I can't believe my eyes!"

“……”

Everyone stopped in shock, staring blankly at the qiē in front of them, after a long time, when everyone came back to their senses, a strong sense of excitement, mixed with strong joy, rose from the bottom of everyone's hearts, to join such a company, everyone knows, they have come to the right place, it is definitely the wisest choice in their lives.

After coming back to their senses, everyone saw the eye-catching arrows not far away, as well as the words "Welcome new employees", and everyone walked towards the office building.

After three days of new employee reporting time, a lot of new faces appeared in Tianfeng Technology Company, and these new employees were assigned to various positions to start their new life journey.
