Chapter 132 Director Zhendong, why don’t you report a new project? (4k)

It was a thermal imager for outdoor use, and in the future, it became a civilian product.

Strictly speaking, they are all night vision equipment, but infrared searchlights (with infrared cameras), low-light night vision devices, and thermal imagers are different.

The infrared searchlight actively emits infrared rays, and then the infrared camera receives the reflected infrared rays to form an image to achieve the effect of night vision. Just think of it as an ordinary searchlight, except that it emits infrared rays.

The advantages are that the technology is easy to use and could be developed in the 40s and 50s. The disadvantages are that it consumes a lot of energy, has a short range, poor contrast, and the unbearable point in military use is that in other people's night vision equipment, it is like a big light bulb, shouting to the world "I'm here, come and shoot me." After the first generation, its military application was quickly eliminated.

Low-light-level night vision devices actually achieve night vision by amplifying very weak visible light. Later, many technical branches were developed, which generally have their advantages, so they have been developed and applied. However, one of its problems is that it was burned by strong light in the early stage and blinded during the day in the later stage.

Thermal imagers use heat signals to form images directly. To some extent, they can be seen as an enhanced version of infrared cameras. However, they do not actively transmit signals, but passively receive heat signals and form images directly. Generally speaking, they have 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 the temperature is different from the background, it can be detected. Moreover, it can penetrate smoke. As for the disadvantages, expensive things generally have only one disadvantage: expensive.

Starting from the third generation of tanks, thermal imagers are basically standard equipment.

Thermal imagers usually use indium antimonide arrays or mercury cadmium telluride arrays. The former is low-priced and has good performance, but has a narrow bandgap, while the latter has an adjustable bandgap, a wide wavelength range, a high carrier concentration, and a high price.

Coincidentally, these two materials had already appeared in 59, and there might be surprises if they were extracted from them.

The things that were taken out were much bigger than those seen in the store, and looked different. Gao Zhendong was mentally prepared for this.

If two chips can be turned into two cabinets, then nothing else is impossible.

It can be extracted, and it seems that both the objective lens and the eyepiece are available. This surprised Gao Zhendong. It did not turn it into an infrared searchlight + infrared camera, so everything is possible.

As usual, a set of materials was attached. Gao Zhendong put away the thing, which he didn't know whether it was a thermal imager or not, picked up the materials and studied them carefully.

After reading the equipment introduction, Gao Zhendong was a little bit amused. This dog system, if you say it is strict, it can at least help you fix a bug. If you say it is loose, you actually don’t get any advantage.

Based on the existing technology, the system provided Gao Zhendong with a thermal imager that was within the technological limits.

——Line array scanning thermal imager.

This thing didn't appear until the 70s.

To put it simply, based on the technology in 59, it was impossible to achieve high resolution, or even a 128*128 infrared imaging unit, as this involved a whole set of related technologies.

However, by the 70s, the material consistency problem was finally solved. However, without the integrated semiconductor technology of later times, there was no way to integrate tens of thousands or hundreds of thousands of infrared detector units onto a flat surface.

Because each discrete unit must be connected to at least two wires, which are two wires in the physical sense, and with so many units, it is very difficult to achieve consistency.

An acceptable image has a resolution of at least tens of thousands of pixels.

The researchers had an idea. They thought, "Well, I can take a small number of detector units with good consistency and arrange them in one or several rows. This way, there will be fewer wires and it will be easier to achieve consistency."

Although there are fewer lines, it is obvious that no image can be formed regardless of the resolution of 1*100 or 2*100.

So the researchers came up with another idea: Why not move this linear infrared detector array, take images row by row within the imaging range, and then piece the images together?

Therefore, after adding the not-too-exaggerated technologies such as primary refrigeration, vacuum dewar flask insulation, and germanium-containing infrared optical equipment, the line scanning infrared thermal imager appeared.

Even in Gao Zhendong's previous life, line scanning was still one of the mainstream technologies for low-cost thermal imagers.

The system was designed for Gao Zhendong, with a 1*120 line array that achieves a thermal imaging resolution of 320*240.

The detection units of the linear array use long-wave mercury cadmium telluride material, which is a good thing and is used not only in infrared detection.

The effect is certainly not comparable to that in the future, but for now, it’s like a scorpion’s shit—unique.

Holding this set of things, Gao Zhendong felt a little troubled. Basically, every item in it needed to go through the trial-production process before the source could be clearly explained. He couldn't even use the Lou family as a cover, because the equipment, materials and materials needed for the trial-production were not something that ordinary businessmen could get.

Even if it is called half a city, it is not possible! These are different from the crystal triodes that have been laid out for civilian use.

However, thinking about his gradually stable position in and outside the system, he would always be able to find an opportunity to get this thing out.

This thing has been leading the world for more than ten years. Don't panic, don't panic.

Moreover, this thing has an additional benefit. It is not necessary to develop the whole thing. It would be enough to make certain units jump for joy if we first master the mass production preparation and bandgap adjustment technology of long-wave mercury cadmium telluride.

Looking at the thick pile of explanatory materials, Gao Zhendong was extremely happy.
-

In the NF material trial production workshop of Jingcheng 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 uses a side-blown converter. He wants to use AOD (argon oxygen refining) to carry out decarburization refining.

This method was put into operation in the United States in 1968.

Prior to this, decarburization was either done by blowing oxygen or by expensive vacuum melting.

However, both methods have limitations. The temperature range of oxygen decarburization is limited, and although carbon is removed, other components are also oxidized, such as chromium.

Not to mention vacuum melting, that is really cool, but also really expensive.

The specific principle of argon oxygen refining is relatively complicated. In simple terms, it is a method of decarburization through a mixture of oxygen and argon in a certain proportion. Argon is used to promote decarburization and reduce oxidation of other components.

Gao Zhendong gave the people from Beijing Iron and Steel Plant different argon and oxygen mixing ratios for the three decarburization stages, as well as the decarburization control targets for the three stages.

When the decarburization target is reached, the stage of reduction, refining and composition adjustment will begin. At this time, pure argon gas will be blown. Gao Zhendong explained the requirements, additives and time of these two stages to the people at Beijing Iron and Steel Plant.

Finally, Gao Zhendong has made clear regulations on the requirements for each step, including steel production, calming, and ingot casting.

In fact, there is no research on this process, it's all operation.

After the ingots are cast, they can be sent to the third rolling mill for rolling. Refining is a relatively important process. Deputy Director Fan of Jingcheng Steel Plant also attended the event to show his importance.

Watching the operation of the AOD refining method, Deputy Director Fan had an idea. This method looks good. At least it has a theoretical basis. Maybe it is really a low-cost and efficient decarbonization refining method.

While waiting, Deputy Director Fan rushed back to the office and told Director Tan of Beijing Iron and Steel Plant about his ideas.

"Director Tan, today I saw the new refining method called AOD proposed by Comrade Gao Zhendong of the Third Rolling Mill. I think it is very interesting. I think it can be used not only for the trial production of NF materials, but also for other materials with similar requirements."

Director Tan looked at Deputy Director Fan and asked, "What does AOD mean? What do you mean?"

These two "meanings" obviously have different meanings.

"AOD stands for argon oxygen refining, which was coined by Comrade Gao Zhendong and was also the one who developed it. What I mean is that we should take this opportunity to cooperate with the Third Steel Rolling Mill and use AOD refining as a new process as a scientific research project. We have to do it anyway, so why not do it all at once?"

Director Tan was very excited: "Hey, your idea is good. The NF material has been trial-produced and the new process has been developed and can be promoted. But will they let you get on board?"

Deputy Director Fan said, "Since you think it's good, then I'll go and talk to Comrade Gao Zhendong. I think Comrade Gao Zhendong didn't take this new process seriously. He just quietly used it as a common process in the NF material trial production."

Director Tan stopped him: "No, I will go. We are just taking advantage of their help. I will go in person to show my sincerity. Once they have reached an agreement, I will go to their factory and apply jointly."

Deputy Director Fan thought about it and realized that his behavior was abrupt. If he wanted to get on the car, he naturally had to show his 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 phase of decarbonization control targets had been achieved, and judging from the online indicators, the situation was very good.

This made Director Tan and Deputy Director Fan, who saw this scene, want to get in the car even more.

Director Tan walked up to Gao Zhendong, greeted him warmly, and solemnly brought up the matter of establishing the AOD project.

Gao Zhendong thought about it and realized, yes, he had never thought of this problem. As expected of a steelmaker, he is very keen on technical application. This technology can be used not only for NF, but also for other materials.

I only focused on the trial production of materials, but didn't think about the promotion of technology.

Regardless of whether there was any utilitarian element in Beijing Steel's suggestion, the result was that it promoted the use of the AOD refining method, and the result was good, which was enough.

Moreover, 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 hand it over to Beijing Iron and Steel Plant, which is a good match for our profession.

Jinggang Plant did not completely gain the upper hand, as the NF trial production workshop, personnel, materials, and electricity were all provided by others.

I don't have the energy to apply for the project, so it's just right for Beijing Steel Plant to do it, as they are familiar with the process.

Only a fool would not do something like this where there are results, everyone works together to promote the good, it benefits both oneself and others, and it is a win-win for all parties.

Gao Zhendong's mind was already spinning in an instant, and he smiled and said to Director Tan, "Director Tan's suggestion is great. To be honest, I only focused on my own material trial production and neglected the technology promotion. Director Tan has a long-term vision and considers things carefully, and has maximized the effect of this material trial production."

Although these words were meant to flatter the other party, they also seemed to be speaking on the same level as Director Tan.

But Director Tan didn't feel uncomfortable at all. Instead, he felt excited and happy because he was praised by Gao Zhendong.

Hearing that Gao Zhendong agreed to the matter without hesitation, Director Tan secretly praised Gao Zhendong for his good style: "Haha, Director Zhendong is straightforward and has a good style. Then we can take advantage of this. I will contact Director Yang right away, and we will report this AOD process research and development project together."

Gao Zhendong smiled and nodded: "Then I'll trouble you, Director Tan. I really can't spare the time here."

Director Tan shook his head: "No need for you to step aside, no need for you to step aside, your trial production work is more important. We all know the significance of this material. Don't worry, we will take care of the rest. Director Gao, you have solved the most important problem, and leave the other small matters to us."

The two chatted for a while, and seeing that the goal of the second step of decarbonization had been achieved and the situation was still good, Director Tan hurried back to arrange to report the project to the third steel rolling mill.

But don’t let the dust settle and complete success of the AOD process here, but the project there has not been approved yet, otherwise it will become a small joke in the happy event.

After receiving a call from Director Tan of Beijing Iron and Steel Plant, Director Yang of the Third Rolling Mill was completely confused because he had never heard that Gao Zhendong was going to develop a new technology.

After Director Tan explained everything clearly, Director Yang suddenly realized that this was the case. This was also Gao Zhendong's old habit.

For the purpose of thermocouples, 591 high-temperature alloy was quietly developed, and 592 and 593 armored steels were also developed.

For the sake of ESR, a batch of artillery steel was refined for the Grassland Tractor Factory.

In order to find a partner, I made DJS-59. No, maybe it’s the other way around.

Now, in order to trial-produce NF materials, it doesn’t seem so strange to develop a new AOD process.

No, next time I see this kid’s new project, I have to watch it carefully from beginning to end. Maybe there is something incredible hidden in it.

I secretly sighed that Lao Tan was lucky enough to get a ride.

If I had known earlier that Gao Zhendong had mixed AOD, a new technology, into the NF trial production and didn't take it seriously, I could have gotten more money from Old Tan.

Director Yang fully agreed with Director Tan's proposal. From what Director Tan said, the Third Rolling Mill didn't have to do anything and the honor of developing the new process would be in its pocket.

The Third Rolling Mill developed a new process, and the Beijing Steel Plant assisted and promoted it, which was perfect.

What does it mean for brother units to work together as one? What does it mean for social cooperation to be superior? Isn't that it?

Director Yang immediately agreed with Director Tan’s proposal over the phone, and the two finalized all the details of the cooperation over the phone.

After hanging up the phone, Director Yang said to himself: "This Gao Zhendong really can shine at any time."

Having said that, he couldn't help but look at an application report on his desk.
