When Li Tianfeng returned to his office, he saw Ouyang Feifei sitting there with a smile on his face. Li Tianfeng smiled with joy, "Feifei, go, let's get off work."

Ouyang Feifei nodded and held Li Tianfeng's arm. The two of them chatted while walking, talking and laughing. Li Tianfeng said: "Feifei, I have been practicing cooking skills for a while. I wonder what have I prepared for me tonight?"

Ouyang Feifei said: "In the afternoon, I sneaked out quietly and bought a lot of ingredients. I will wait for you to have a good time."

Li Tianfeng smiled and joked, "Okay, I'll be there during working hours. I won't punish you for two hundred o'clock."

Ouyang Feifei laughed happily, "Mr. Li, I can't be considered a mid-slip service. I am serving the leader and also working."

Li Tianfeng smiled and then said jokingly: "That's what I want to pay for overtime. You are also serving your leaders at night."

"whee……"

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

Ouyang Feifei was good at cooking and was quite good at cooking. In the past, she often cooked by herself when she was at home. Now, after becoming Li Tianfeng's girlfriend, Ouyang Feifei often exercised her cooking skills and signed up for some cooking training classes. Her cooking skills are already very good.

After having a great time, Li Tianfeng even sighed that he could go to the hall and go to the kitchen, and he should be talking about Ouyang Feifei.

e Factory, precision casting workshop.

Several workers were carrying out casting operations. In the vacuum smelting furnace, the titanium alloy had melted and had completely met the casting requirements. Several workers were chatting and joking while preparing to cast.

These workers cast titanium alloy receivers, which have high requirements and are not from e-factory. They were entrusted by Tianfeng Technology Company to be responsible for casting.

At present, the "tfwz001" type turboshaft engine has completed the design of many important and important parts. Some parts are already processing, and some parts are forged or casting blanks. Tianfeng Technology's casting workshop and forging workshop are still under construction, so e-factory is entrusted 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. Not that, the titanium alloy receiver of the "tfwz001" type turboshaft engine is being precision cast in the casting workshop of the e-factory factory.

It is also coincidental that a batch of titanium alloy receivers are cast at the same time as this titanium alloy receiver. In fact, the "tfwz001" type turboshaft engine and the turboshaft engine are similar in size and grade, and some parts are even the same material grade, but the design level of the two is high and low, and the weight level of the engine is almost the same, the output power of the "tfwz001" type turboshaft engine is 1800kw, and the output power of the turboshaft engine is 1200kw.

These workers who are carrying out casting operations. One of them seems to be older, about fifties. The squad leader of this casting class and the other workers obey the squad leader's advice. Everyone will do whatever they say.

A seemingly young worker said: "The team leader, Tianfeng Technology's titanium alloy receiver, they also sent the parts casting operation process regulations. The preparation was very detailed and the various parameters were very comprehensive. It was amazing."

Unexpectedly, the squad leader curled his lips and said disapprovingly: "Xiao Zhang. Do you think the process regulations are very good and beautiful. I think this is something that is good but not good. Everything is done as I said. I, Lao Liu, have worked in casting work all my life, and I am the process regulations."

A worker next to him echoed: "That's right, our squad leader is our working craftsmanship, and the technicians in our workshop often come to ask for advice."

Squad Leader Liu nodded proudly, and then "guided" several of his workers to start a series of operations. Tianfeng Technology's titanium alloy receivers have two in total. Under Squad Leader Liu's "guidance", these two receivers were casted. After waiting for complete cooling, you can open the sandbox tomorrow morning and take out the parts.

The titanium alloy receiver of the turboshaft C engine is also cast next to it, and six pieces are cast at one time. Everyone is busy and casting them. The two different receivers are cast by everyone, so everyone’s feelings are obviously different.

Xiao Zhang, a young worker, said: "Squad leader, the casting process of these two titanium alloy receivers of Tianfeng Technology is really good. They are much easier to cast than our turboshaft C titanium alloy receiver. However, we did not operate according to the process regulations provided by others, will there be any problems?"

A worker next to him said, "Xiao Zhang, who is our squad leader? Don't worry, there is no problem. When the sandbox is unpacked tomorrow morning, it will definitely be a fully qualified part. Don't worry." After that, he patted Xiao Zhang's shoulder.

There are still two brushes in the casting workshop of factory e. Otherwise, Li Tianfeng would not entrust these two titanium alloy receivers to factory e for casting. These two receivers are important parts and are also stress-bearing parts. The position on the engine is to connect the compressor receiver and the combustion chamber receiver, which is called "intermediate receiver", and the parts requirements are relatively high.

However, when designing the receiver, Li Tianfeng fully considered the casting process of the parts and the process of mechanical processing after casting. Although the parts are very advanced and important, they have better processability.

Especially when the titanium alloy receivers of the same type as the turboshaft C engine of factory e are cast in the same team, the comparison is more obvious. It is clear which is better and which is inferior in craftsmanship. Otherwise, Xiao Zhang would not have said that just now.

The casting was completed, but Xiao Zhang was still inexplicably worried, because Xiao Zhang had carefully read the casting process regulations provided by Tianfeng Technology. The casting process regulations of Tianfeng Technology deeply attracted Xiao Zhang. Xiao Zhang admired Tianfeng Technology very much. Unexpectedly, his squad leader did not cast according to other people's process regulations.

Will there be a big problem? Xiao Zhang was still thinking this way until he got off work at noon.

...

In the morning, Li Tianfeng drove to the e factory, first went to Yang Xianfeng's office to sit down, and then entrusted the e factory to help him forge a few parts blanks. Then, Li Tianfeng wanted to take a look at the two intermediary receivers entrusted the e factory to cast.

Yang Xianfeng had an important meeting in the afternoon, and the person who accompanied Li Tianfeng was Liu Qingshan, the deputy chief engineer. The two were talking and laughing, and walked slowly side by side like old friends, and walked towards the casting workshop.

Li Tianfeng felt relaxed 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 receivers. According to the casting strength of e Factory, he would definitely be able to cast at one time.

Li Tianfeng didn't know that Squad Leader Liu of the casting workshop did not cast according to the requirements of the process regulations he provided, but completed the casting with his "rich experience". At this time, they should be opening the sandbox and taking out the parts.

Li Tianfeng and Liu Qingshan, the two of them were chatting while walking.

Liu Qingshan said: "Mr. Li, your Tianfeng Technology has developed so quickly, and it is amazing to start designing and developing engines by yourself."

Li Tianfeng said: "Mr. Liu, many of our Tianfeng Technology's hardware facilities are not perfect. Maybe in the early stages of development, I have to ask you to help you."

"Where, where, as long as we can develop a truly advanced aircraft engine, what's the point of helping us do such a little favor?" Liu Qingshan said.

Li Tianfeng was quite happy. Whether it was Yang Xianfeng or Liu Qingshan, Li Tianfeng thought they were all good people, good people, and good to himself.

Soon, the two of them also walked to the door of the casting workshop and saw this large new factory. Of course, Li Tianfeng knew that this was built by the e factory two years ago by more than 200 million yuan. In the domestic casting industry, it is definitely a first-class foundry building.

At the same time, Li Tianfeng secretly said in his heart that when Tianfeng Technology's casting workshop was completed, its scale and advanced level must be above this factory. In terms of investment scale alone, Tianfeng Technology's casting workshop has reached nearly 600 million yuan, and some advanced casting equipment is not comparable to that of e-factory.

When I walked into the casting workshop, a technical director of the casting workshop came to receive it. He and the two of them soon arrived at the team responsible for the casting of intermediary receivers.

The workers were opening the sandbox. The six-piece receivers of the turboshaft C in the factory e were already opened one by one. The workers were cleaning the tiny sand grains on the receiver, holding soft brushes, cleaning them carefully. Of course, Li Tianfeng knew the six-piece receivers of the turboshaft C. Otherwise, the three years Li Tianfeng worked in the factory e before would have been in vain.

Seeing these six-piece receivers, Liu Qingshan was delighted, 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 technology level has improved very quickly. I don't think the passing rate of these six-piece receivers is low."

Director Hu of the casting workshop was praised and was very happy: "Mr. Liu, this is everyone's credit. We have established a technology research team. Not only are there key process technicians leading the team, but there are also front-line workers among the team members. For example, the turboshaft C receiver casting public relations team has experienced squad leader Liu."

Liu Qingshan was very satisfied, nodded and said in praise: "It's good to fully absorb front-line workers into the research team."

Squad Leader Liu was excited and knew that Liu Qingshan brought Li Tianfeng over, and must have wanted to see the casting of the two intermediary receivers of Tianfeng Technology. So Squad Leader Liu waved his hand and directed several workers to unbox.

Seeing that his two intermediary receivers were about to come out of the sandbox, Li Tianfeng was looking forward to it. These two receivers were considered relatively important parts. If the casting was successful, Tianfeng Technology would be able to get back to it immediately and start a series of subsequent mechanical processing. After the processing was completed, a series of tests and verifications could be carried out.
