Chapter 327 This thing costs money!
The two of them rode back to the courtyard and said that Cao Cao had arrived. As soon as Silhu jumped out of the car, they happened to see Qin Huairu walking around the courtyard. This was good for her situation. She seemed worthy of it. He is a father of two children and has rich experience.
Qin Huairu saw the two people coming back and said with a smile: "Hey, Silly Zhu, this is a high standard. Director Gao will be your coachman."
Silly Zhu chuckled: "Look what you said , my brother, next time, I will pedal and he will sit."
After that, he handed over the lunch box in his hand: "You are lucky today, Zhendong invited comrades from other units to eat, there is not much left. Less, but good stuff.”
Qin Huairu was not polite, stretched out his hand to take it, and turned to greet He Yuyu: "Yuyu, you share yours first, I can take the rest with me."
He Yuyu smiled and put the lunch box away Take it and bring it into the house.
Seeing a few people chatting outside the house, Lou Xiaoe simply brought out the teacup to Gao Zhendong: "Zhendong, come, drink tea."
Gao Zhendong took it, and Lou Xiaoe took the opportunity to chat with her outside the house. They chatted together.
Seeing this scene made Sha Zhu a little jealous: "Hey, Zhendong, you have such good luck."
Gao Zhendong recognized this and took a sip of tea with a smile: "That's right."
Qin Huairu heard this and teased Silly Zhu: "Silly Zhu, if you are jealous, hurry up and find one yourself. Since your blind date was ruined by Xu Damao last year, why haven't you taken care of it anymore?"
Silly Zhu patted his head: "Hey, there won't be many chores after that. Think about it again, wait. Yuyu has graduated from junior high school, so that Yuyu will not be wronged. "
In these days, after graduating from junior high school, you can have a good way out. Not to mention, Shazhu's idea is quite towards his sister. of.
Qin Huairu rolled his eyes: "It's a monkey year, and it's not a problem for you to be single all the time. How about I take a look in the factory and help you?"
< br>
Under Qiao's beautiful smile, the two of them seemed to be in a trance suddenly.
Gao Zhendong was drinking tea next to him, and Lou Xiaoe was leaning against him. He said nothing, just watching the two people talking, hey, I won't say anything, let's see what you look like in the end.
Now, there is probably nothing between the two of them.
If by chance, Si Zhu can find someone else that suits his needs, that would be good. If he still runs all the way to the dark side on Qin Huairu's path, that's not impossible.
Si Zhu shook his head in a daze, as if shaking something out of his head, with a slightly unnatural smile: "That's okay, thank you, Sister Qin, But let’s talk about it first, it just depends on your luck.”
Qin Huairu smiled and glanced at him sideways: "De Xing, do you think someone is rushing to marry you? I still have two questions about whether I can fall in love with you. It will depend on fate."
This is a supercilious look. , Silly Zhu was so excited that he didn't know what was going on, but Gao Zhendong saw very clearly that the pretty widow's supercilious look was too lethal to the old bachelor.
This kind of lethality has nothing to do with feelings for the time being, it purely depends on the power of appearance.
Ah, thief Cao!
At this time, He Yuyu came out with a lunch box in one hand and a large tea vat in the other, his eyes a little red.
The lunch box in the right hand was handed to Qin Huairu: "Sister Qin, lunch box."
The tea jar in the left hand was handed to Silly Zhu: "Brother, drink water."
Silly Zhu laughed and took the tea jar. : "Haha, girls are pretty good too. One of my own is a thief."
He Yuyu glanced at him, turned to Qin Huairu and said: "Sister Qin, let me thank you in advance for my brother. Thank you for your hard work. Please take care of him first.”
Although they are not very old, they naturally become wiser early in their family’s situation, and they speak in a sensible way.
Gao Zhendong looked at these people and felt that they felt strange, so he took Lou Xiao'e into his arms, said goodbye to them, and went back to his home.
After entering her home, Lou Xiaoe had a strange look on her face: "Zhendong, why do they feel weird together? Master He and Sister Qin will have nothing to do with each other."
Gao Zhendong smiled and shook his head: "No, at least not now. In the future, it will be their business." After that, I didn’t think much about the rest at all and just threw it behind my head.
——
In Gao Zhendong's office, Liang Fafa was holding several translucent tubes and a report, reporting something to Gao Zhendong.
"Director Gao, this is the first batch of officially trial-produced Type B thermocouples. It has been tested and the temperature range is consistent with what you gave. It can work continuously at 1600°C and short-term at 1800°C. There is no problem with this batch. . ”
Gao Zhendong was writing something and didn’t have time to read the report, so he asked him directly.
“How big is the deviation?”
“The full scale is at the level of 2.5 thousandths, but the minimum is about 1°C.”
"Well, that means that the measuring range does not exceed 5°C. This accuracy is quite sufficient." For such a large range, the accuracy generally depends on two indicators. One is the full-scale ratio, and this is the actual measurement. The accuracy when the range is relatively large, and the other is that when the actual measurement range is relatively small, there will be a deviation that cannot be reduced.
So many sensors will have two values when labeling accuracy, such as 0.25%/1℃ and 0.5%/1cm.
The accuracy of type B is much higher than the typical accuracy of type K of 0.75%/2.5℃.
Liang Fafa smiled and said: "It's true, Director Gao, when it comes to accuracy, stability, and upper temperature limit, I really can't find a better thermocouple than this one. And judging from the electromotive force, , this sensor does not require compensation wires. ”
Gao Zhendong nodded, that's for sure. Not to mention now, it will be difficult to find him in a few decades.
However, it is not without its shortcomings. First of all, it is expensive, and then
“But the requirements for the working environment are a bit harsh, and compared to the K type, the response is very slow. Generally speaking, it can only It is said to be no more than 180 seconds.”
Three minutes! This was expected by Gao Zhendong. The shortcomings of this thing are just like this. If it didn't have these shortcomings, even if it was that expensive, its application would be wider.
"It doesn't matter. If this thing is bigger, it will be bigger. At least it is enough for the craftsmanship that Sister Fang and the others are doing."
Liang Fafa nodded with joy on his face. Seeing Director Gao's intention, this thing is good. This year, my old Liang, a second-class Liehuo Technology, seems to be stable.
Gao Zhendong thought for a while and arranged: "You write a briefing immediately. One copy is sent to the department by calling the confidential room. The other one is desensitized and only the core parameters are left. Give it to the party. Send it to my sister. She is alone outside supporting her brother’s factory in technological innovation. As a family member, we must provide her with timely support, haha.”
This is why people rely on big factories. It becomes more popular when supporting other units. This person not only represents himself/herself, but there is often a more powerful force behind him/her.
To give an inappropriate example, it is generally easier for people in finance and development and reform to take temporary posts at lower levels than to take temporary posts in some Qingshui Yamen.
Liang Fafa agreed, immediately packed up the materials and went to implement Gao Zhendong’s arrangements.
——
In a certain steel plant, in the technical transformation laboratory, Fang Yinghong was communicating with people from the local factory about something.
“No, the temperature is too high. When it reaches above 1300℃, the process cannot be controlled. It is difficult to control the temperature by observation or experience, and it is impossible to respond in time.”
“ Fang Gong, can you improve the K-type thermocouple? The temperature difference is only a hundred or two degrees."
Fang Yinghong shook his head: "As long as we use direct measurement, this is a hurdle that cannot be overcome. ”
"What about indirect measurement?"
"The accuracy is not enough. This originally requires an accuracy of 10°C. For K-type direct measurement, the full-scale error is almost over. Indirect measurement is even more difficult to say. ”
At this moment, I heard someone looking for Fang Yinghong.
She looked up and saw that it was the colleague from the research laboratory who came with her to support her. She was the one responsible for liaising with her family, and she felt happy.
Sure enough, the visitor spoke with good news: "Sister Fang, good news! Director Gao and Engineer Liang worked overtime and have built a new thermocouple. Director Gao asked me to show you the situation. If there is no problem, go through the formalities immediately, and we will support you with a batch as quickly as possible! Mr. Liang is already producing trial batches, just waiting for your formalities.”
After speaking, he reached out and handed over a piece of paper.
Fang Yinghong and the technical director of the local factory were overjoyed when they heard this. Fang Yinghong reached out to take it and unfolded it. The comrades of the local factory stretched their heads and watched together.
1600℃, 1800℃, 0.25%/1℃.
These indicators made them smile!
"Gong Fang, I will immediately ask the people in our factory office to handle the relevant procedures. Your factory is so awesome. This kind of problem has been solved so quickly. I don't believe we can't solve it this time!"< br>
Fang Yinghong nodded and said: "Well, you go and go through the specific procedures. I will modify the signal amplification circuit here. The thermoelectromotive force of this B-type thermocouple is a bit small and the sensitivity is a bit low. It turns out that the amplification factor of the amplification circuit is not enough."< br>
This is also one of the shortcomings of type B thermocouples, but it is not a fatal problem. The signal is small and can be amplified, but the measurement range is not enough and cannot be imposed.
The comrades from the local factory praised it repeatedly: "Okay, I'll leave this matter to you. Our comrades' experience in this area is not good enough. For other bits and pieces, feel free to leave it to us."
< br>Seeing the dawn of success at a glance, they were also excited. The big factory in Beijing was extraordinary, and the support for the comrades in their unit was really great.
Just when Fang Yinghong and the others were fully mobilized, the leaders of the 17th Machinery Department were also happy.
After receiving a report from Secretary Sun, the confidential office received a briefing from the third rolling mill. When they raised funds by themselves and developed a new thermocouple, he realized that Gao Zhendong must be messing with something again. .
As soon as he opened the materials, he was frightened by the generosity of the third rolling mill.
“This thing costs money!”
What the hell, single crystal ruby is used as a protective tube, and platinum and rhodium are used as electrodes? Are you not ready to live your life?
