Chapter 129 ESR Conclusion, the Dawn of Portable Mobile Storage (4k)

Tuesday, ESR test workshop, Beijing No. 3 Steel Rolling Plant.

All members of the ESR project team gathered together, including experts sent by the 17th Ministry of Machine Building.

Today is the day for ESR final acceptance.

Although this project was not funded by the Ministry, when the Third Steel Rolling Mill project was established, only a letter was sent to the Ministry for filing.

However, when it came to the project completion and acceptance, the department still sent experts to assist in the work.

Among them were the first batch of predecessors who were engaged in ESR. They successfully put the ESR process into production in 58.

In the workshop, a corner was cleared and a number of tables were set up, where experts and key members of ESR were gathered.

The smelting of a furnace of alloy steel for the final acceptance report is nearing completion. Under the sliding crystallizer, the ingots that are getting longer and longer are emitting a slightly dark red color.

Although the test results have not yet come out, the experts sent by the department are obviously very positive about the idea of ​​sliding crystallizer.

Several experts were talking in low voices.

"This sliding crystallization idea is very interesting. It can directly produce ingots with a large aspect ratio."

"According to their chief engineer Comrade Gao Zhendong, continuous casting can be considered in the next step." Now the factory has openly called Gao Zhendong the chief engineer.

"You know what? Young people are smart."

"Young man? I asked around, and the achievements of this Chief Engineer Gao, just the ones he personally presided over and can talk about publicly, will shock you. Most people may not be able to produce even one in their lifetime."

"It is a blessing for the country that there are more and more young people like this."

"."

Gao Zhendong has already reported on the project status on behalf of the entire ESR project team, so they are now mainly looking at the results and communicating.

Although the final report contains complete and detailed reports and analyses of various experiments during the research process, the rule is that seeing is believing, and it is better to burn a furnace than to say a thousand words.

Soon, the ingot reached the predetermined length and the test group began to finish the operation.

At this time, an expert who had not participated in the discussion but had been staring at the voltmeter and ammeter, occasionally writing something on a notebook, shouted.

"It's amazing. Their product consumes very little electricity. It can actually save 10% to 15% of the electricity per ton of steel made by our ESR, which is about 200 degrees."

When the experts who were still discussing heard this, they stopped discussing and turned to ask the expert: "Old Yuan, are you sure?"

Engineer Yuan pushed his notebook forward and said, "Look, I basically recorded every voltage and current fluctuation during their smelting process. I calculated them piece by piece and added them up. There may be some errors, but they won't be too big."

Several experts leaned over and carefully looked at the data in Engineer Yuan's notebook.

"Eh? Is it really that low?"

“Is it the problem caused by the different conductivity of steel grades?”

"For the purpose of acceptance and comparison, they refined traditional steel this time. I know the power consumption per ton of steel for this type of steel, ESR. It's the number Lao Yuan gave me."

"Based on this power consumption alone, even if there are some other problems, this project is considered a success and has application prospects."

Engineer Yuan pointed to the current curve he had drawn and said, "Did you notice that this current is very stable? The droplet rate is very evenly controlled. And I noticed that their staff has not adjusted the equipment since the start of the experiment. This means that their current control is really automatic, as Chief Engineer Gao said."

The current curve drawn by manual recording is rather rough, and many things are difficult to see, but it can be seen that it is indeed very stable.

Several experts looked at each other.

"It seems that the ESR has been optimized very well. Now we just have to wait for other data."

However, the wait lasted so long that they didn't even have time to have a meal.

There is no way around it. It takes time for the steel ingot to cool down, which is commonly known as being hot.

Although a small diameter crystallizer was used this time to save time and the smelting length was not long, cooling still takes time.

During the meal, they also had a lot of exchanges with the people in the ESR research group. The more they listened, the more they felt that the ESR process improvement of the Third Steel Rolling Mill was brilliant.

In the afternoon, all the test data were sent over urgently. Looking at these data, all the experts felt that this time the acceptance was a sure thing.

Those who are quick-witted have already started considering introducing the technology.

"Look at this current curve. It's so stable."

"Well, except for the initial oscillation, the wavelength of the subsequent oscillation is very long and the amplitude is very small." This person should not be studying automation.

"Indeed, the overshoot is not large, the adjustment time is short, and the error band is very narrow." This person must be majoring in automation.

"Just this one thing makes it worth introducing."

"The fluorine emissions are much lower than ours."

"Well, while fluorine emissions are reduced, the increase in hydrogen is not obvious."

"Have you noticed that their decreasing power control model is very interesting? In different stages, the power is controlled just right, which is both sufficient and energy-saving."

"The composition changes before and after remelting are well controlled, and the segregation amount is also good."

"There is no problem with the metallographic structure. The toughness and strength have been significantly improved before and after remelting, and the isotropy is also very good."

"."

The experts looked excited and discussed for a long time. Finally, they gave their acceptance opinions.

Leaving aside clichés, there are just a few core points in general.

The ESR process improvement research of Beijing No. 3 Steel Rolling Plant has the advantages of low power consumption, excellent process control, good product consistency, high repeatability, and greatly reduced pollution. At the same time, based on the existing ESR technology, the quality of the finished product has been further improved.

Its improvement and optimization projects such as sliding crystallization, decreasing power control, automatic control of working electrical parameters, quaternary/quinary low-fluorine slag system, etc. have advanced design concepts and obvious optimization effects.

In summary, the ESR process optimization and improvement research project of Beijing No. 3 Steel Rolling Plant has passed the acceptance and was successfully completed!
When the expert group finished signing and finally read out the acceptance result, there was jubilation at the scene.

This project is not like other projects, which are basically completed by Gao Zhendong alone, and others are mainly assisting. However, due to the scale, workload, and Gao Zhendong's own busy work, everyone is deeply involved in this project and has contributed a lot of effort.

Therefore, the success of this project has given everyone a greater sense of accomplishment.

Of course, the first credit must go to Gao Zhendong. If he had not provided the overall principles, original design of each subsystem, detailed design of the automatic control system, system design, and answered questions, it would have been almost impossible to complete this project.

Everyone rushed towards Gao Zhendong, lifted him up and threw him into the air many times.

This is also one of the traditional ways of celebration.

The project's chief commander, Director Yang, deputy chief commanders, Director Chen, Deputy Director Li, and several commanders also applauded and shook hands with each expert to express their gratitude.

Gao Zhendong was finally let down by the excited people and met up with the commanders to enjoy the joy of success together.

The broadcasting room of the factory's publicity department also received the notification of acceptance at the first time and broadcast the broadcast script that had been written long ago.

This project is different from other projects. Thermocouples are of great significance but slightly less weight, and 591~593 materials are things that cannot be publicized publicly. Only ESR is significant, weighty, and publicizable enough.

"Great news, great news. The ESR process improvement and optimization research project, which was initiated by our factory with self-raised funds and organized resources, passed the project final acceptance organized by the 17th Ministry of Machinery this afternoon. The experts present at the meeting"

At the same time, the news of the acceptance was immediately transmitted back to the 17th Ministry of Machine Building by the staff of the 17th Ministry of Machine Building who were on site. The leader instructed that he be informed as soon as there was a result.

This is not an exaggeration. If you know the history of scientific research at that time, you will know that technology was scarce at that time, and it was normal for such news to alarm the leaders of the 17th Ministry of Machine Building.

Unlike Gao Zhendong's previous life, even people from the Municipal Science and Technology Bureau might not care about things of this level.

When the leader received the news, he burst into laughter.

He was happy not only about the success of this scientific research project, but also because it proved that the Third Steel Rolling Mill, as a collective, had formally completed the entire process of a scientific research project. This was of greater significance to the Third Steel Rolling Mill than the ESR improvement itself.

As the saying goes, "A single flower does not make spring, a hundred flowers in full bloom make the garden full of spring."

If the previous projects could only prove Gao Zhendong's excellence, then the successful ESR improvement proved that the Third Steel Rolling Mill had initially acquired the ability and conditions for innovation.

There is a huge difference in work ideas, work methods and self-confidence between those who have gone through the whole process and those who have not.

Just like the war eagle in the sky, it took decades to master a Seventh Master, but the process of moving from a Raptor to a Mighty Dragon is getting faster and faster, which is one of the reasons.

There are many similar examples.

Thinking of this, the leader picked up the phone and called Director Yang who had already returned to the office: "The conditions for the matter I told you about last time are now ripe. You can submit a report now."
-

At the same time, the chief engineer of the computing center, who had been itching to get his equipment processed for a whole day and night, finally received the news that the equipment commissioned by Director Gao had been completed.

He immediately called Gao Zhendong's factory and said, "Please tell Director Gao Zhendong that we have already processed the drawings he sent us. Please ask him to come over for inspection as soon as possible."

After hanging up the phone, Chief Engineer Chi felt unhappy: "This Third Steel Rolling Mill is too stingy. They are reluctant to install a telephone in Director Gao's office."

When Gao Zhendong received the news, it was almost time to get off work in the afternoon. In fact, he was also itching to do something. He already had a recorder and had written the read-write drivers. The only thing missing was the analog-to-digital conversion device.

Thinking of this, he ran to the factory office and called Chief Engineer Chi: "Chief Engineer Chi, is the product ready?"

"It's done, it's done. Why don't you come over and take a look? Check it out."

"Now? It's almost time to get off work. I'm coming here now to disturb your rest."

"It doesn't matter, it's all for work."

The two eager people hit it off immediately and decided that Chief Engineer Chi would bring his men to the computing office to wait for Gao Zhendong, and Gao Zhendong would go there immediately.

Gao Zhendong took one of the two tape recorders he had brought to the computer room and rode his bike towards the computing office.

It was after dinner time that Chief Engineer Chi, who had been waiting anxiously, finally saw Gao Zhendong. However, he suppressed his strong curiosity and ate first.

He guessed that Gao Zhendong had not eaten yet, so everything was prepared in the cafeteria, and he and the staff were waiting for Gao Zhendong to come and eat together.

The group of people didn't talk much. They were very familiar with each other and there was no need to say much.

Everyone scooped up their rice and headed straight for the computer room. According to Gao Zhendong's request, several analog-to-digital conversion devices were all there.

When Gao Zhendong arrived, he found that the equipment, required wires, and connectors were all ready. Even the wires and connectors were soldered directly according to the wire sequence requirements on Gao Zhendong's drawings.

Gao Zhendong took out the tape recorder from his backpack. Chief Engineer Chi and Director Li were stunned when they saw it. What was this? They recognized the two speakers on the sides, but they didn't know what the small box in the middle covered with a transparent plastic sheet was.

Gao Zhendong put in a useless music tape as a prank. When the melodious music started playing, the staff at the operation center were stunned. This thing was too rare and they really wanted it.

Director Li and Chief Engineer Chi were also dumbfounded, but the reasons for their dumbfounding were different.

Director Li looked at Gao Zhendong and asked hesitantly, "Director Gao, this thing is good. It's very good. It's much more portable than a record player for listening to music. I want to get one, but what does this thing have to do with a computer?"

Chief Engineer Chi didn't say anything, but just looked at Gao Zhendong. It was obvious that he had the same question.

Gao Zhendong smiled and said, "Director Li, Chief Engineer Chi, guess what this thing is used to record music?"

The two shook their heads. They couldn't tell. These tapes weren't in transparent boxes, so they couldn't see the rolled tapes. Only a short strip was visible at the top, so they couldn't make out anything.

But Chief Engineer Chi had a better ability to associate ideas: "Punch tape?"

Gao Zhendong smiled and said, "Boss Chi is amazing, this is pretty close. This is the music signal recorded on a tape."

As soon as they heard the word "magnetic", Li and Chi suddenly realized what the magnetic drum and magnetic core were used for. They were used to record data!
Mr. Chi asked, "Director Gao, is this used to store data? It's so small? So light?"

The dual-speaker recorder is actually not very big. Although it has not been miniaturized to the extreme, it is only about 30*15*8cm.

Of course, this seemed very large to the people in Gao Zhendong's previous life, but compared with the several layers of 0.5*0.5 meter boards of transistor memory and the cabinets of magnetic core memory next to it, it could be said to be small, exquisite, lightweight and portable.

Gao Zhendong smiled and nodded: "This thing was given to me by my future father-in-law. It was originally used to listen to music. It uses magnetic signal storage and outputs analog audio signals. But then I thought, the magnetic signal of this thing is retained when the power is off, and it is convenient and portable. Isn't it just right to use it to store data? I spent some time to make a conversion circuit and wrote a read and write program. If it can be realized, then we will have a portable mobile data storage device."

Take some time, and say a few words to make the people in the computing office's eyes jump.

Portable mobile storage!
Director Li and Chief Engineer Chi were immediately excited.

　1 completed.
