Chapter 132 Director Zhendong, don’t you sign up for a new project? (4k)
That is an outdoor thermal imager. In the future, it will be a civilian product.
Strictly speaking, they are all night vision equipment, but infrared searchlights (with infrared cameras), low-light night vision devices, and thermal imaging cameras are different.
Infrared searchlight actively emits infrared rays, and then the infrared camera receives the reflected infrared rays to achieve night vision effect. Just think of it as an ordinary searchlight, except that it emits infrared rays.
The advantage is that the technical difficulty is low and it can be done in the 40s and 50s. The disadvantages are high energy consumption, short distance, poor contrast, and the point that cannot be tolerated when used in military applications is that in other people's night vision equipment, I am like a big light bulb, shouting "I am here" all over the world. , come and hit me." After the first generation, its military applications were quickly eliminated.
Low-light night vision devices actually achieve night vision effects by enhancing and amplifying very weak visible light. Later, many technical branches were developed. Generally speaking, they have their own advantages, so they have been under development and application. However, it has a stubborn problem of being burned by strong light in the early stage and becoming blind during the day in the later stage.
The thermal imager directly uses thermal signals to create images. To a certain extent, it can be regarded as an enhanced version of an infrared camera. However, it does not actively emit signals, but passively receives thermal signals and directly images. Generally speaking, it has the best detection performance, especially for heat signals. Everything flying in the sky, running on the ground, and swimming in the water is generating heat. As long as it is different from the background temperature, it can be detected. Moreover, it can penetrate smoke. Disadvantages: Expensive things generally have only one disadvantage: they are expensive.
In the third generation of tanks, thermal imaging cameras are basically standard equipment.
It is more common for thermal imaging cameras to use indium antimonide arrays or mercury cadmium telluride arrays. The former is low in price and has good performance, but has a narrow bandgap. The latter has an adjustable bandgap and a wide range of wavelengths. High concentration, high price.
Coincidentally, these two materials have already appeared in 1959, and there may be surprises when extracted.
The items brought out were much larger and different in appearance than those seen in the store. Gao Zhendong was mentally prepared for this.
Two chips can be turned into two cabinets, so what else is impossible?
It can be extracted. It seems that the objective lens and eyepiece are included. This surprised Gao Zhendong. It did not turn him into an infrared searchlight + infrared camera, so everything is possible.
As usual, a set of materials came with it. Gao Zhendong put away this thing that he didn’t know if it was a thermal imaging camera, picked up the materials, and studied it carefully.
After reading the equipment introduction part, Gao Zhendong was a little bit dumbfounded. This dog system, if you say it is strict, it can help you get a bug. If you say it is loose, in fact, you don’t have it. Take advantage.
The system is based on the existing technical foundation and gives Gao Zhendong a thermal imaging camera that is within the technical limits.
——Line array scanning thermal imager.
This thing originally didn’t appear until the 1970s.
To put it simply, based on the technical foundation of 1959, it is impossible to achieve not only high resolution, but also a 128*128 infrared imaging unit, which involves a whole set of related technologies.
But in the 1970s, the problem of material consistency was finally solved. However, without future integrated semiconductor technology, there was no way to integrate tens of thousands or hundreds of thousands of infrared detector units onto a single plane.
Because each discrete unit must be connected to at least two wires, two in the physical sense, and with so many units, consistency is very difficult to achieve.
An acceptable image must have a resolution of at least tens of thousands of pixels.
The researcher had an idea. Hey, I will take a small number of detector units with good consistency and arrange them in one or several columns. In this way, there will be fewer lines and the consistency will be easier to achieve.
Although there are fewer lines, it is obvious that imaging is impossible regardless of the resolution of 1*100 or 2*100.
Then the researchers got smart again. I made this linear infrared detector array move and image line by line within the imaging range, and then put the images together, wouldn't it be enough?
Therefore, after adding not-too-exaggerated technologies such as first-level refrigeration, vacuum Dewar insulation, and germanium-containing infrared optical equipment, line scanning infrared thermal imaging cameras appeared.
Even in Gao Zhendong’s previous life, line scanning was still one of the mainstream technologies for low-cost thermal imaging cameras.
The system provided Gao Zhendong with a 1*120 line array to achieve a thermal imaging resolution of 320*240.
The long-wave mercury cadmium telluride material used in the detection unit of the line array is a good thing and is not only used in infrared detection.
The effect will definitely not be comparable to what it will be in the future, but now, it is a scorpion pooping - the only one.
Holding this set of things, Gao Zhendong felt a little troublesome. Basically every item in it needed to go through the trial production process before the source could be clearly explained. The Lou family could not even be used as a cover because the trial production required equipment and materials. , not something ordinary businessmen can handle.
Even if it is called half the city! These are different from the transistors that are already in civilian use.
But thinking that my status inside and outside the system has gradually stabilized, I can always find opportunities to get this thing out.
This thing is more than ten years ahead of the world. Don’t panic, don’t panic.
Moreover, this thing also has a side benefit. You don’t need to go all out. If you first master the mass production preparation and bandgap adjustment technology of long-wave mercury cadmium telluride, you can make some units jump with joy.
Looking at the thick pile of explanatory materials, Gao Zhendong was extremely happy.
——
In the NF material trial production workshop of Beijing Iron and Steel Plant, the crude steel has been refined and is now being decarbonized and refined in the side-blown converter according to Gao Zhendong’s requirements.
This step is why Gao Zhendong wants to use a side-blown converter. He wants to use AOD (argon oxygen refining method) for decarbonization and refining.
This method was put into production in Citigroup in 1968.
Before this, either oxygen blowing was used for decarburization or costly vacuum melting.
Both methods have limitations. The temperature rise range of oxygen blowing decarburization is limited, and the carbon is removed, but other components are also oxidized, such as chromium.
Not to mention vacuum melting, it is really cool, but it is also really expensive.
The specific principle of the argon-oxygen refining method is relatively complicated. Simply put, it is a method of decarburization through a certain proportion of oxygen and argon mixture. Argon is used to promote decarburization and reduce the content of other components. Oxidized.
Gao Zhendong gave the people at the Jingcheng Steel Plant different argon and oxygen mixing ratios for the three decarbonization stages, as well as the decarbonization control targets for the three stages.
When the decarbonization target is reached, it will move to the reduction, refining, and composition adjustment stages. At this time, pure argon gas will be blown. Gao Zhendong made the requirements, additives, and time of these two stages clear to the people at the Beijing Steel Plant. explain.
Finally, Gao Zhendong has made clear requirements for each step of tapping, sedating and ingot casting.
In fact, there is no research in this process, it is all operation.
After the ingot casting is completed, it can be sent to the third rolling mill for rolling plates. Refining is a relatively important process, and Deputy Director Fan of the Beijing Steel Plant was also present to express his attention.
Looking at the operation of the AOD refining method, Deputy Director Fan thought, this method looks good, at least the theoretical basis is there, it may really be a low-cost and efficient decarbonization refining method.
While waiting, Deputy Director Fan rushed back to the office and told Director Tan of the Capital Steel Plant what he thought.
"Director Tan, today I saw the new refining method called AOD by Comrade Gao Zhendong of the Third Steel Rolling Plant. I think it is very interesting. I feel that it can be used not only for the trial production of NF materials, but also for other materials. Anyone with similar requirements can use this method."
Director Tan looked at Deputy Director Fan: "What does AOD mean? "
The two "meanings" obviously have different meanings.
"The full name of AOD is argon-oxygen refining. It was started by Comrade Gao Zhendong and was researched by him. What I mean is that we should take this opportunity to cooperate with the third steel rolling mill and use this AOD refining as a new process. It’s a scientific research project that has to be done anyway, so it can be done in one go.”
Director Tan was very excited: “Hey, your idea is good, NF materials have been trial-produced, and new processes can be developed. Promoted. But they will let you get on the bus?”
Deputy Director Fan said: “Since you think it’s good, then I think Comrade Gao Zhendong didn’t take this into consideration. The new process was taken seriously, and it was quietly used as a normal process in the trial production of NF materials."
Director Tan stopped him: "No, I'll go ahead with this matter. It’s like we’re just taking someone else’s ride. I’ll go there in person to be more sincere. After he’s settled the deal, I’ll go to their factory and apply jointly.”
Deputy Factory Director Fan thought about it himself. This approach is abrupt. If you want to get in the car, you must have the best attitude.
Director Tan put down his work and went to the NF trial production workshop with Deputy Director Fan.
By the time they arrived, the first-stage decarbonization control target had been reached. Judging from the online indicators, the situation was very good.
This made Director Tan and Deputy Director Fan more eager to get on the bus after seeing this scene.
Director Tan walked up to Gao Zhendong, greeted Gao Zhendong warmly, and solemnly proposed the establishment of the AOD project.
Gao Zhendong thought about it, yes, I really didn’t think of this problem. As expected of someone who is engaged in steelmaking, he is very keen on technical applications. This technology can be used not only for NF, but also for other materials.
I only focused on the trial production of materials, but I never thought about the promotion of technology.
Whether or not there is a utilitarian element to this suggestion from Jingang Steel Plant, the result is to promote the use of the AOD refining method, so long as the result is good.
And I am only interested in the trial production of NF materials. I don’t have time for the next step of research, improvement and promotion of AOD. It is just right to leave it to the Beijing Iron and Steel Plant, which is the professional counterpart.
The Jingang Steel Plant is not completely taking advantage. The NF trial production workshop, personnel, materials, and electricity are all paid for by others.
I didn’t have the energy to apply for the project, so Jingang Steel Works came to do it, and I happened to be familiar with it.
Only a fool would not do this kind of thing that has achieved results, where everyone is carrying a sedan chair and carrying others, benefiting oneself and others, and a win-win situation for all parties.
All of a sudden, Gao Zhendong’s mind was finished and he smiled at Director Tan: “Director Tan’s proposal is great. To be honest, I only focus on the trial production of my own materials. For The technical promotion was neglected. Director Tan still stood tall and took a long-term view, and made the most of the material trial production."
Although he was speaking to the other party. He has a high hat, but he seems to be speaking at the same level as Director Tan.
Director Tan, however, didn't feel it was against the rules at all. Instead, he felt faintly excited and happy because he was wearing Gao Zhendong's hat.
Hearing that Gao Zhendong did not hesitate and agreed to the matter immediately, Director Tan secretly praised Gao Zhendong for his high style: "Haha, Director Zhendong is straightforward and has a high style. Then we can take advantage of this. . I will contact Director Yang immediately, and we will submit the AOD process research and development project together. ”
Gao Zhendong smiled and nodded: "Then I'll bother you, Director Tan. I really can't get away from here."
Director Tan shook his head: "There's no need to get away, there's no need for you to get away, your trial production work is more important. We all know the significance of this material. Don’t worry, we’ve taken care of the other things. Director Gao has solved the main problem. Leave the other minor matters to us.” After chatting for a while, seeing that the goal of the second step of decarbonization had been achieved and the situation was still good, Director Tan quickly went back to discuss the project application with Luo and the Third Steel Rolling Mill.
Don’t forget that everything about the AOD process here has been settled and completely successful, but the project over there hasn’t been approved yet, so it becomes a little joke in a happy event.
After receiving a call from Director Tan of the Capital Steel Plant, Director Yang of the Third Rolling Plant was completely at a loss. He had never heard that Gao Zhendong was going to develop a new process.
When Director Tan explained everything clearly, Director Yang suddenly realized that this was what happened and it was Gao Zhendong's old habit.
For thermocouples, 591 high-temperature alloy was quietly produced, and 592 and 593 armor steel were also produced.
For ESR, a batch of gun steel was refined for the Prairie Tractor Factory.
In order to find a partner, I made DJS-59. No, it might be the other way around.
Now, for the trial production of NF materials, it doesn’t seem so strange to develop a new AOD process.
No, next time this guy's new project, you have to look at it carefully from beginning to end, there might be something amazing hidden in it.
I secretly sighed that Lao Tan had gotten so lucky and hitched a free ride.
If I had known that a new technology like AOD was being mixed into NF trial production by Gao Zhendong and ignored, then I could have taken more advantage from Lao Tan.
For Director Tan’s proposal, Director Yang applauded with both hands. According to Director Tan’s words, the third rolling mill did not need to do anything, and the honor of developing this new process was lost.
The third rolling mill developed a new process, and Beijing Steel Plant assisted and promoted it, which was perfect.
What is a game of chess between brothers and what is the superiority of social cooperation? This is it.
Director Yang immediately agreed to Director Tan’s proposal on the phone, and the two finalized all the cooperation details on the phone.
After hanging up the phone, Director Yang said to himself: "This Gao Zhendong can really shine at any time."
At this point, he couldn't help but look at his desk an application report.
