E factory, precision machining center.

Last night, Li Tianfeng slept comfortably in the State Guest Hotel, the five-star hotel is really good, if it weren't for the fact that he still needs to go to work today, Li Tianfeng would definitely have a lazy sleep.

"Brother Li, you are amazing." Zhang Can came up from the processing site and looked happy as soon as he entered the office.

"Why, so happy." Li Tianfeng asked with a smile.

"Brother Li, you instructed me to improve the process, that is, the process of processing the turboprop C turbine disc semi-finish, good guy, according to Brother Li's method, the processing efficiency has been more than doubled, and the pass rate is 100%."

Semi-finishing is the process between rough turning and fine turning, the machining accuracy is higher than that of rough turning, and the machining allowance is larger than that of fine turning.

In addition, the material of the turboprop C turbine disc is a nickel-based superalloy, which has high hardness and poor machinability, and has always been very conservative in the processing of this material.

The so-called superalloy is a high-temperature metal material that can work for a long time under certain stress conditions. This metal has excellent high-temperature strength, good oxidation and hot corrosion resistance, good fatigue performance, fracture toughness and other comprehensive properties, and has become an irreplaceable key material for the hot end components of military and civilian gas turbine engines.

However, people with processing experience know that all parts of high-temperature alloy materials are generally more difficult to process, and who has advanced processing experience and processing methods in high-temperature alloys has mastered a key technology.

Li Tianfeng naturally has such a key technology, and he guided Zhang Can a little, but he didn't expect Zhang Can to be happy like this.

In the whole office, the atmosphere is good, He Baitao and Li Dawu are also good, Li Tianfeng guided the three of them a little, and was about to go to the processing site to take a look, Cheng Gang came over in person, and saw his boss come in, Zhang Can and the three of them sat up straight, looking like they were working hard.

Li Tianfeng smiled slightly, shook his head slightly, and then said, "Director Cheng, what is the matter with you coming here in person?" ”

Cheng Gang smiled, it seems to be a good thing, sure enough, Cheng Gang took out a red envelope and said, this is Mr. Liu entrusted me to bring it, you successfully solved the broaching process problem of the turboshaft C engine turbine disk, which Mr. Liu promised to reward you. ”

Five thousand!

Seeing the thick red envelope, Zhang Can and the other three, who were originally working seriously, suddenly had their eyes lit up, and then they gave Li Tianfeng a "Brother Li, you cow" look.

Li Tianfeng happily accepted the 5,000 yuan, this is the reward he deserves, there is nothing to shirk, but Li Tianfeng still said politely: "Thank you, Mr. Liu, thank you Director Cheng." ”

Cheng Gang smiled slightly, "Originally, Liu always planned to come over to you in person, but at present, as the last few key parts of the turboshaft C engine are also processed, and the turboshaft C engine has entered the assembly stage, Mr. Liu is very busy, and he has almost been soaked in the assembly workshop for the past two days." ”

Liu Qingshan is a hard-working technical cadre, with excellent skills and hard work, otherwise it would not be possible to become the deputy chief engineer of Factory E step by step.

As a brand-new model, the turboshaft C engine must have a series of technical problems after entering the final assembly, and after the final assembly, it will be tested subsequently, which may also expose a series of technical problems, which are enough for Liu Qingshan to be busy for a while.

"Mr. Liu cares about me so much, thank you, Mr. Liu." Li Tianfeng is more modest, not impatient or impatient.

Coming over to send money is obviously not the purpose of Cheng Gang's coming, sure enough, Cheng Gang said: "Xiao Li, we have all seen your excellent performance recently, and there will be a national aviation industry system skills competition soon, and this competition happens to be our turn to host the ...... of factory E."

Cheng Gang roughly talked about the situation of this skill competition, which is held once every five years, and each time it is unprecedented, and it has a great influence in the aviation industry system.

The competition is divided into several groups, front-line workers participate in the lathe group, grinding group, milling group and so on more than a dozen groups, engineering and technical personnel to participate in the design group, process group, etc.

"Xiao Li, we happen to have a recommended quota in our precision machining center, and the office meeting of the center has agreed to recommend you to participate in the competition of the process group." Cheng Gang told Li Tianfeng the good news.

Participating in such a competition is naturally an opportunity to show his face, Li Tianfeng will definitely not refuse, and immediately said gratefully: "Thank you, leader." ”

Cheng Gang nodded, said a few words to Li Tianfeng, and then left with a good look. As soon as Cheng Gang left, Zhang Can and the other three immediately returned to their true colors, and where there was still a trace of "serious work", they swarmed around and congratulated one after another.

"Brother Li, congratulations, this time Brother Li will definitely show his strength and come back with a first."

"Yes, Brother Li, as long as you enter the top five in the process group, you will get the title of national craft master, this title is the title of a cow in our aviation industry system, and it is also one of the highest honorary titles of our process technicians."

"National Master of Crafts" is a supreme honorary title, there are so many elites in the country, only a few people can get this title, only once in five years, and only five people each time.

Li Tianfeng scolded with a smile: "Don't be a sycophant, where is such a title so easy to get." ”

……

Within two days, the E factory officially issued a document and notice about the skills competition of the national aviation industry system, and many people in the entire E factory knew the good news, and many people were eager to try it.

A recommended quota in the process group of the precision machining center was directly set by Li Tianfeng, but the competition quota for the rest of the groups was not determined, but took the initiative to sign up, and then screened the way.

"Lao Zhao, you signed up for the competition of the lathe group!"

"Well, Lao Ding, you signed up for the milling group competition, and with your senior technician Lao Ding, you will definitely be able to get your hands on it."

"Where, where, this time it's national, we have hundreds of thousands of people in the aviation industry system, and it's so simple to get the ranking." The old miller is very modest.

……

The registration and screening process was quick, and by Friday, a detailed list was first compiled to the engineering and technical department of Plant E.

The engineering and technology department is responsible for the first round of screening of the list, this round of screening should reduce at least two-thirds of the people, and then determine the list to send to Liu Qingshan, as the chief technologist of the E factory, Liu Qingshan, the deputy chief engineer, is responsible for the determination of the final list of the E factory.

Huang Xuewen, deputy director of the Engineering Technology Department, held a list in his hand, a list of a group, such as the list of the lathe group has more than a dozen people, all of which are recommended by the subordinate units of the E factory, and the number of participants in the E factory is only five, and more than half will be cut here.

The rest of the grinders, millers, drillers, etc., the list is greatly streamlined, Huang Xueren holds a pen, thinks that the unqualified ones are a big fork, and if they feel qualified, they will hit a hook.

Not long ago, Huang Xuewen made a bet with Li Tianfeng and lost his face fiercely, and Huang Xuewen, who was depressed, stayed in his office and rarely went out, especially not daring to go to the precision machining center.

Coincidentally, the director went abroad two days ago, Huang Xuewen temporarily presided over the work of the engineering technology department, Huang Xuewen, who was depressed, swept away the depression, and felt that he was full of energy.

Holding the list of participants in the craft group, Huang Xuewen swept it slightly, saw Li Tianfeng's name, and sneered directly, and then hit a big fork, after hitting this fork, Huang Xuewen felt like he drank snow water in June, and his heart was refreshed.

"Hmph, I still want to participate in the competition, let's dream!" Huang Xueren thought in his heart, and there seemed to be a kind of refreshment of revenge.

With a stroke of the pen, after the list was confirmed, Huang Xuewen said loudly: "Little Sun, come over here, print out the final list, and then send it to Mr. Liu for signing." ”

……

"Brother Li, today is the weekend, where are we going to play?"

Early in the morning of Saturday, Li Tianfeng was still sleeping soundly in bed, Ouyang Feifei's phone called, and Li Tianfeng, who was sleeping in a daze, picked up the phone, "Feifei, you don't have to work overtime, besides, it's early in the morning, brother, I'm sleeping." ”

"It's really lazy, it's eight o'clock and you're still sleeping, Brother Li, what did you do last night, I'll come to you, and I'll buy you breakfast by the way......" Ouyang Feifei said a lot, looking cheerful, like a lark.

"Come here, then, I'm hungry." Li Tianfeng said.

Last night, Li Tianfeng was busy all night in the small remote factory he rented, and he was busy until late before coming back to sleep.

Thinking of the small bag of raw diamonds in his drawer, Li Tianfeng thought in his heart, twenty or thirty million should be almost in hand again.

"Do you want to get up first, Fei Fei will come over later." Li Tianfeng thought so in his heart, but he slept late last night, and he was really a little reluctant to get up.

After struggling in bed for a long time, Li Tianfeng couldn't get up, it felt really good to fall asleep in bed, but at this time, there was a knock on the door, it should be Ouyang Feifei who had already bought breakfast and came over.

I took a casual dress cover, put on my slippers and got up to open the door.

"Oops!" Seeing that Li Tianfeng, who opened the door, was wearing a pair of boxer shorts, the shorts were bulging, and he was wearing a short sleeve casually, witnessing this scene, Ouyang Feifei's face turned slightly red, and she almost screamed.

"Quick, come in, I'm hungry." As he spoke, he picked up a dumpling and ate it in one bite.

"I haven't rinsed my mouth yet, go wash up." Ouyang Feifei scolded with a smile, put the breakfast she bought on the table, and pushed Li Tianfeng to brush his teeth and wash his face.
