Back in his office, Li Tianfeng saw Ouyang Feifei sitting there with a smile on his face, Li Tianfeng smiled happily, "Feifei, let's go, let's get off work." ”

Ouyang Feifei nodded, holding Li Tianfeng's arm, the two chatted while walking, talking and laughing, Li Tianfeng said: "Feifei, I have been practicing my cooking skills for a while, I don't know what to prepare for me tonight?" ”

Ouyang Feifei said: "I sneaked out quietly in the afternoon and bought a lot of ingredients, so you can have a good meal." ”

Li Tianfeng smiled and joked: "Okay, slip during work hours, see if I don't punish you with two hundred oceans." ”

Ouyang Feifei laughed happily, "Mr. Li, I can't be regarded as a slippery middle, I am serving the leader, and it can be regarded as work." ”

Li Tianfeng smiled, and then said jokingly: "Then in this way, I still have to pay overtime, and you are also serving the leader at night." ”

"Hee-hee-hee......"

The two talked and laughed, got out of Tianfeng Technology, and drove to Ouyang Feifei's residence. In the evening, Ouyang Feifei really showed her cooking skills and made a sumptuous dinner.

Ouyang Feifei was originally good at cooking, and she was quite good at it, when she was at home before, she often cooked by herself, but now, after becoming Li Tianfeng's girlfriend, Ouyang Feifei often exercises her cooking skills, and she also signed up for a cooking training class, and her cooking skills are already very good.

After Meimei's feast, Li Tianfeng even sighed, going up to the hall and going down to the kitchen, it should be Ouyang Feifei.

E factory, precision casting workshop.

Several workers are engaged in casting operations, and in the vacuum smelting furnace, the titanium alloy has been melted and fully meets the pouring requirements, and several workers are chatting. Joking aside, while preparing for casting.

These workers cast titanium alloy casings, which have relatively high requirements, and they are not from Factory E, but are entrusted by Tianfeng Technology Company to Factory E for casting.

Presently. "TFWZ001" turboshaft engine has completed the design of many important key parts, some parts have begun to be processed, some parts of the blank is forging or casting blank, Tianfeng Technology's casting workshop and forging workshop are still under construction, so entrusted E factory to be responsible for processing.

With the good relationship between Li Tianfeng and Zhu Maohua, Yang Xianfeng, Liu Qingshan and others, this is not a problem at all, no, the titanium alloy casing of the "TFWZ001" turboshaft engine is being precision cast in the casting workshop of Factory E.

Also coincidental. In fact, the "TFWZ001" turboshaft engine and the turboshaft C engine parts are about the same size, and even some parts are the same material grade, but the design level of the two is high, almost the same weight of the engine, "TFWZ001" turboshaft engine output power of 1800kW, turboshaft C engine output of 1200kW.

These workers are working on a foundry. One of them appeared to be older, about fifty years old. The squad leader of this casting class, and the rest of the workers are obedient to the squad leader, and everyone will do what the squad leader says.

A seemingly young worker said: "Squad leader, this titanium alloy casing of Tianfeng Technology, they also sent over the parts casting operation process regulations. It's very well compiled, and the various parameters are very comprehensive, which is remarkable. ”

Unknowingly, the squad leader pursed his lips and said disappreciably: "Xiao Zhang." You think it's great that the process specification is good-looking, I think this is a useless thing, a qiē do what I say, my Lao Liu has done a lifetime of casting work, I am the process specification. ”

A worker next to him echoed: "That is, our squad leader is our living process, and the technicians in our workshop often come to ask for advice." ”

Squad leader Liu nodded proudly, and then "guided" several workers under his command to start a series of operations, Tianfeng Technology's titanium alloy casing, a total of two, under the "guidance" of squad leader Liu, the casting of these two casings was finally completed, just wait for complete cooling, you can open the sandbox tomorrow morning, and take out the parts.

The titanium alloy casing of the turboshaft C engine is also cast next to it, casting six pieces at one time, everyone is busy, and the casting is completed, and the two different casings are cast by everyone, and everyone's feelings are obviously different.

Xiao Zhang, a young worker, said: "Squad leader, the casting process of these two titanium alloy casings of Tianfeng Technology is really good, and the casting is much easier than the titanium alloy casing of our vortex shaft C, and it is also a lot easier, but we do not operate in accordance with the process regulations provided by others, will there be problems." ”

A worker next to him said: "Xiao Zhang, who is our squad leader, rest assured, there is no problem, wait for the sandbox to be unpacked tomorrow morning, it must be fully qualified parts, rest assured." After speaking, he also patted Xiao Zhang's shoulder.

In the casting workshop of factory E, there are still two brushes, otherwise, Li Tianfeng will not entrust these two titanium alloy casings to factory E for casting, these two casings are important parts, but also stressed parts, the position on the engine is to connect the compressor casing and the combustion chamber casing, the name is called "intermediary casing", and the parts requirements are relatively high.

However, when designing the casing, Li Tianfeng fully considered the casting process of the parts, and also considered the process of machining after casting.

In particular, the same titanium alloy casing of the turboshaft C engine of the E factory is cast in the same team, and the contrast is more obvious, and the craftsmanship is superior and inferior, which is clear at a glance, otherwise, Xiao Zhang would not have said this just now.

The casting is completed, but Xiao Zhang is still inexplicably worried, because Xiao Zhang has seriously read the casting process regulations provided by Tianfeng Technology, and the casting process regulations of Tianfeng Technology have deeply attracted Xiao Zhang, Xiao Zhang admires Tianfeng Technology very much, and he thought that his squad leader does not cast in accordance with the requirements of other people's process regulations.

Will this be a big problem, until he gets off work at noon, Xiao Zhang is still thinking about it in his heart.

……

In the morning, Li Tianfeng drove to Factory E, first went to Yang Xianfeng's office to sit down, and then entrusted Factory E to help him forge a few parts blanks, and then, Li Tianfeng wanted to take a look at the two intermediary casings that were entrusted to Factory E for casting.

Yang Xianfeng had an important meeting in the afternoon, accompanied by Li Tianfeng was deputy chief engineer Liu Qingshan, the two talked and laughed, like old friends, walked slowly side by side, and walked towards the foundry workshop.

Li Tianfeng was in a relaxed mood, because Tianfeng Technology not only provided detailed and scientific casting process regulations, but also Li Tianfeng had full confidence in the craftsmanship of these two intermediary casings, and according to the casting strength of E factory, it would definitely be able to be qualified for one-time casting.

How did Li Tianfeng know that the Liu squad leader of the foundry workshop did not cast in accordance with the requirements of the process regulations provided by himself, but completed the casting with his "rich experience".

Li Tianfeng, Liu Qingshan, the two walked and chatted at the same time.

Liu Qingshan said: "Mr. Li, your Tianfeng Technology has developed really fast, and it is really remarkable that you have started to design and develop engines by yourself." ”

Li Tianfeng said: "Mr. Liu, many of our Tianfeng Technology's hardware facilities are not perfect, and we may have to trouble you to help a lot in the early stage of development." ”

"Where, where, as long as we can develop a truly advanced aero engine, what is it for us to help with such a small favor." Liu Qingshan Road.

Li Tianfeng was happier in his heart, whether it was Yang Xianfeng or Liu Qingshan, in Li Tianfeng's opinion, they were all good people, good people, and good to themselves.

Soon, the two also walked to the door of the foundry workshop, and saw this large new plant, Li Tianfeng of course knew that this was built by the E factory two years ago with more than 200 million yuan, and it was definitely a first-class foundry plant in the domestic foundry industry.

At the same time, Li Tianfeng secretly said in his heart, waiting for the completion of Tianfeng Technology's foundry workshop, its scale, its first process dù must be above this plant, just the scale of investment, Tianfeng Technology foundry workshop has reached nearly 600 million yuan, some advanced foundry equipment, not E factory can be compared.

Walking into the casting workshop, soon a technical director of the foundry workshop came to receive him, and with the two of them, he soon came to the team responsible for the casting of the intermediary casing.

The workers are opening the sandbox, and the six receivers of the turboshaft C of factory E have been opened one by one, and the workers are cleaning up the fine sand particles on the receiver, holding a soft brush, and cleaning them more carefully.

Seeing these six pieces of casing, Liu Qingshan was overjoyed, walked forward quickly, and looked carefully, the casting quality seemed to be good, so Liu Qingshan was in a good mood and praised: "Director Hu, your casting process level has improved very quickly, and I don't think the pass rate of these six casings is low." ”

Director Hu of the foundry workshop was praised and was very happy: "Mr. Liu, this is everyone's credit, we have set up a process research team, not only led by backbone process technicians, but also front-line workers among the team members, such as the scroll C casing casting public relations team has experienced Liu squad leader." ”

Liu Qingshan was very satisfied, nodded, and said approvingly: "It is not bad to fully absorb front-line workers into the research team." ”

Squad Leader Liu was excited in his heart, and he also knew that Liu Qingshan brought Li Tianfeng over, and he must have wanted to take a look at the casting of the two intermediary casings of Tianfeng Technology, so squad leader Liu waved his hand and instructed several workers to open the box.

Seeing that his two intermediary receivers were about to come out of the sandbox, Li Tianfeng looked forward to a while, these two receivers are relatively important parts, if the casting is successful, Tianfeng Technology can be taken back immediately, and a series of follow-up machining can be started, and after the processing is completed, a series of tests and verifications can be carried out.
