Chapter 327 This thing costs money!
The two men rode their bikes back to the courtyard, and as soon as they spoke of the devil, Sha Zhu had just jumped off the bike when they saw Qin Huairu strolling around the courtyard. This was good for her situation, as it seemed that she was worthy of being a mother of two children and was very experienced.

Qin Huairu saw the two men coming back and said with a smile: "Oh, Silly Zhu, this is a high standard. Director Gao will be your driver."

Sha Zhu chuckled and said, "Look at what you said. We are brothers. Next time, I will pedal and he will sit."

After saying that, he handed over the lunch box in his hand: "You are lucky today. Zhendong invited comrades from other units to dinner. There are a lot of leftovers, and the food is good."

Qin Huairu was not polite and took it. She turned around and greeted He Yushui: "Yushui, you take your share first, and I'll take the rest."

He Yushui took the lunch box with a smile and brought it into the house.

Seeing a few people chatting outside the house, Lou Xiaoe simply brought out the teacup to Gao Zhendong: "Zhendong, come, have some tea."

Gao Zhendong took it, and Lou Xiaoe joined them outside the house to chat.

Seeing this scene, Sha Zhu felt a little jealous: "Hey, Zhendong, you are so lucky. There is nothing to say."

Gao Zhendong had to admit this, and took a sip of tea with a smile: "That's right."

Qin Huairu heard this and teased Sha Zhu: "Sha Zhu, if you are jealous, just find one for yourself. Since your blind date was ruined by Xu Damao last year, why haven't you tried this again?"

Sha Zhu patted his head and said, "Hey, there will be a lot of things to do after that. Let's think about it again. Let's wait until Yu Shui graduates from junior high school, so that Yu Shui won't be wronged."

Nowadays, graduating from junior high school can be considered a good career path. What's more, Sha Zhu's idea is quite in favor of his sister.

Qin Huairu's eyes turned and she said, "That will take a long time. It's not a good idea for you to be single all the time. How about I go to the factory and find something for you?"

Under the sweet smile, both of them seemed to be in a trance suddenly.

Gao Zhendong was drinking tea next to him, Lou Xiaoe was leaning against him. He said nothing, just watched the two of them arguing. Hey, I won't say anything, let's see what happens to you in the end.

Now, I guess there is nothing between the two of them.

If Shazhu, by chance, can find someone who suits his personality, that would be great too. If he continues on Qin Huairu's path until the end, that's not a bad idea either.

Sha Zhu shook his head in a trance, as if he was shaking something out of his head, and smiled awkwardly: "That's fine, thank you Sister Qin, but let me be clear, this matter depends on chemistry, it may not be successful."

Qin Huairu smiled and glanced at him: "You are such a jerk, do you think she is eager to marry you? It is still unclear whether she will like you or not, we will see what fate has in store for us."

This rolling of the eyes made Sha Zhu shudder. He didn't know what was going on, but Gao Zhendong saw it very clearly. The rolling of the eyes by the pretty widow was too damaging to the old bachelor.

This kind of lethality has nothing to do with feelings for the time being, it relies purely on the power of appearance.

Ah, you bastard!
At this time, He Yushui came out with a lunch box in one hand and a big teacup in the other, his eyes a little red.

He handed the lunch box to Qin Huairu in his right hand: "Sister Qin, lunch box."

He handed the teacup to Sha Zhu in his left hand: "Brother, drink some water."

Sha Zhu laughed and took the teacup: "Haha, the girl is pretty good, she's from our family, so dear."

He Yushui glanced at him, then turned to Qin Huairu and said, "Sister Qin, let me thank you on behalf of my brother. You have worked hard and taken care of him. Please take care of him first."

Although she is not very old, given her family situation, she is naturally sensible at an early age and her words sound very realistic.

Gao Zhendong looked at these people and felt something was strange, so he hugged Lou Xiaoe, said goodbye to them, and went back home.

After entering her home, Lou Xiaoe had a strange look on her face: "Zhendong, why do they feel weird being together? Master He and Sister Qin won't have any problems."

Gao Zhendong smiled and shook his head: "Not really, at least not now. As for the future, that's their business."

Lou Xiao'e is also a carefree person. In her mind, this kind of thing would just flash over for a moment, and she would not think about it any more and would just put it behind her head and forget about it.

In Gao Zhendong's office, Liang Faming was holding a few translucent tubes and a report, reporting something to Gao Zhendong.

"Director Gao, this is the first batch of officially trial-produced Type B thermocouples. We have tested them and the temperature range is consistent with what you gave. It can work continuously at 1600°C and for a short period at 1800°C. There are no problems with the whole batch."

Gao Zhendong was writing something and didn't have time to look through the report, so he asked him directly.

“How big is the deviation?”

"It's at the level of 1 thousandths of the full scale, but the lowest is about °C."

"Well, that means the range does not exceed 5°C, and the accuracy is quite sufficient." For such a large range, the accuracy generally depends on two specific indicators. One is the full-scale ratio, which is the accuracy when the actual measurement range is relatively large. The other is that when the actual measurement range is relatively small, a deviation will occur that cannot be reduced any further.

Therefore, many sensors will have two values ​​when marking their 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, which is 0.75%/2.5℃.

Liang Faming smiled and said, "Indeed, Director Gao, in terms of accuracy, stability, and upper temperature limit, there is really no better thermocouple than this one. And judging from the electromotive force, this sensor does not require a compensation wire."

Gao Zhendong nodded and said, of course, it will be hard to find it even now, even in a few decades.

But it is not without disadvantages. First of all, it is expensive, and then...
“However, the working environment requirements are a bit harsh, and the response is very slow compared to the K type. Generally speaking, it can only be said that it is no more than 180 seconds.”

Three minutes! This was within Gao Zhendong's expectations. This was the disadvantage of this thing. If it didn't have these disadvantages, even if it was so expensive, its application would be wider.

"It doesn't matter. It doesn't matter if it's a little bigger. At least it's enough for the craft that Sister Fang and her team are working on."

Liang Faming nodded, his brows raised with joy. Judging from what Director Gao said, this thing is fine. It seems that I, Liang, will surely get a second place in Liehuo Technology this year.

Gao Zhendong thought about it and arranged: "Write a briefing immediately. Ask the confidential office to pass one copy to the department, and de-sensitize the other copy, leaving only the core parameters, and send it to Sister Fang. She is alone outside to support the brother factory in technological transformation. As her family, we must also provide her with timely support, haha."

This is why people with the support of big companies are more popular when supporting other units. This person not only represents himself/herself, but behind him/her, there is often a more powerful force working secretly.

To give an inappropriate example, people from the finance and development reform departments are generally more likely to be assigned to lower-level posts than those from some government offices that do not pay them much.

Liang Faming agreed, immediately packed up the materials, and went to implement Gao Zhendong's arrangements.

In a technical transformation laboratory of a certain steel plant, Fang Yinghong was discussing something with people from the local factory.

"No, the temperature is too high. When it is over 1300℃, the process cannot be controlled. It is difficult to grasp the temperature by observation or experience, and it is impossible to respond in time."

"Engineer Fang, can you improve the K-type thermocouple? It's only a few hundred degrees off."

Fang Yinghong shook her head: "As long as we use the direct measurement method, this is a hurdle that we can't overcome."

"What about indirect measurement?"

"It's not accurate enough. The accuracy is 10℃. The full-scale error of the K-type direct measurement is almost the limit. The indirect measurement is even more difficult to say."

At this moment, someone was heard looking for Fang Yinghong.

She looked up and saw that it was her colleague from the laboratory who came with her to support her and was responsible for contacting home. She was delighted.

Sure enough, the person who came in opened his mouth with good news: "Sister Fang, good news! Director Gao and Engineer Liang have worked overtime and have developed a new thermocouple. Director Gao asked me to show you the situation. If there is no problem, I will go through the procedures immediately. My family will support you as quickly as possible! Engineer Liang is already producing a trial batch and is waiting for your procedures."

After saying that, he 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 from the local factory stretched their heads to look at it together.

1600℃, 1800℃, 0.25%/1℃.
These indicators made them laugh out loud!

"Engineer Fang, I will ask our factory office to handle the relevant formalities right away. Your factory is really capable. Such a difficult problem was solved so quickly. I don't believe we can't figure it out this time!"

Fang Yinghong nodded and said, "Well, you go and handle the specific procedures. I will modify the signal amplification circuit here. The thermoelectric electromotive force of this B-type thermocouple is a bit small, and the sensitivity is a bit low. The amplification factor of the original amplifier circuit is not enough."

This is also one of the shortcomings of type B thermocouples, but it is not a fatal problem. A small signal can be amplified, but an insufficient measurement range cannot be increased.

The comrades from the local factory praised him again and again: "Okay, I'll leave this matter to you. Our comrades don't have enough experience in this area, so leave the other details to us."

They were very excited when they saw the dawn of success. It was a big factory in Beijing, and it was extraordinary. The support for their colleagues in the unit was really tremendous.

Just as Fang Yinghong and his men were mobilizing on all fronts, the leaders of the 17th Ministry of Machine Building were also feeling happy.

After receiving the report from Secretary Sun and the confidential office receiving a briefing from the Third Rolling Mill that they had raised funds on their own and developed a new thermocouple, he realized that Gao Zhendong must be up to something again.

As soon as he opened the materials, he was shocked by the generosity of the Third Rolling Mill.

“This thing costs a lot of money!”

What kind of crazy thing is this? Single crystal ruby ​​is used as the protective tube, and platinum and rhodium are used as electrodes? Are they not going to live a normal life?
