Chapter 129 ESR Finale, the Dawn of Portable Mobile Memory (4k)
Tuesday, the third steel rolling mill in Beijing, ESR test workshop.
Everyone in the ESR project team was gathered together, as well as experts sent by the 17th Machinery Department.
Today is the day for ESR finalization and acceptance.
Although this project is not a project funded by the ministry, when the third rolling mill project was approved, a letter was only sent to the ministry for filing.
But when it was completed and accepted, the ministry sent experts over to assist with the work.
Among them are the first seniors who made ESR. They successfully put into production the ESR process in 1958.
In the workshop, a corner was opened and a number of tables were set up. Experts and key members of ESR were all here.
The smelting of a furnace of alloy steel for the final acceptance report is coming to an end. Below the sliding crystallizer, the longer (zhang) longer (chang) ingot exudes a faint dark red color.
Although the test results have not yet come out, the experts sent by the ministry are obviously very sure of the idea of sliding crystallizers.
Several experts were communicating in low voices.
“This idea of sliding crystallization is very interesting. In this way, ingots with a large aspect ratio can be directly made.”
“According to their chief engineer, Comrade Gao Zhendong, next The next step is to consider continuous casting. "Now the factory has no hesitation in calling Gao Zhendong the chief engineer.
“Not to mention, young people are just smart in their thinking.”
“Young people? I asked about it, the achievements of Chief Engineer Gao are only things he personally presided over and can be said publicly. , it will shock you, most people may not be able to make one in their lifetime.”
"There are more and more young people like this, and the country is very lucky."
"."
Gao Zhendong has already reported on the project situation on behalf of the entire ESR project team, so they are now Mainly looking at the results and communicating.
Although the report and analysis of various experiments in the research process are very complete and detailed in the final report, according to the rules, hearing is false and seeing is believing. It is not as good as saying a thousand words and ten thousand. Burn a furnace.
Soon, the ingot reached the predetermined length, and the test team began to end the operation.
At this time, an expert who had not participated much in the discussion, but had been staring at the voltmeter and ammeter, writing down something in his notebook from time to time, shouted.
“It’s amazing, their power consumption is very low. It can actually save 10%~15%, more than 200 degrees, than the ESR tons of steel we make.”
When several experts who were still discussing heard this, they ignored the discussion and turned to ask the expert: "Old Yuan, are you right?"
Gong Yuan moved his notebook forward. Tweet: "Look, I basically wrote down every voltage and current fluctuation during their smelting process. The accumulated results after segmented calculations may have errors, but they won't be too big."
Several experts poked their heads over and carefully looked at the data in Yuan Gong's notebook.
"Eh? It's really that low."
"Is it a problem caused by different conductivities of steel types?"
"For acceptance and comparison this time, they refined traditional steel I know the power consumption per ton of steel ESR, which is Lao Yuan’s number.”
“Based on this power consumption, even if there are some other problems, this project can be considered a success and has applications. Prospects."
Gong Yuan pointed to the current curve he drew: "You guys found out that the current is very stable and the droplet rate is controlled very uniformly. And I see that their personnel have improved since they started testing. There is no need to adjust the equipment, which means that their current control is really controlled automatically as Mr. Gao said. ”
The current curve drawn by manual recording is relatively rough, and many things cannot be seen clearly, 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 are waiting for other data."
However, the wait was a long time, and they even had time to have a meal.
No way, the steel ingot takes time to cool, commonly known as hot hands.
Although in order to save time this time, a small diameter crystallizer has been used, and the melting length is not long, cooling still takes time.
While eating, they also had a lot of exchanges with people from the ESR research group. The more they listened, the more they felt that the third rolling mill had done a great job in improving the ESR process.
In the afternoon, all the test data were rushed over. Looking at these data, all the experts felt that this time the acceptance was stable.
I am quick-thinking and have already begun to consider introducing technology.
“Look at this current curve, it’s too stable.”
"Well, apart from the initial oscillation of the curve, the waveform that oscillates later has a very long wavelength and a very small amplitude." This person should not be an automaton learner.
"Indeed, the overshoot is not large, the adjustment time is short, and the error band is very narrow." This person must be a major in automation.
“With this one hand, it is worth introducing.”
“Fluorine emissions are much lower than ours.”
“Well, while fluorine emissions are reduced, The hydrogenation is not obvious.”
"Have you noticed that their decreasing power control model is very interesting? At each different stage, the power is controlled just right, which is both sufficient and energy-saving."
"The composition changes before and after remelting are very controlled. Good, and the amount of segregation is also good."
"The metallographic structure is okay, the toughness and strength are significantly improved before and after remelting, and the isotropy is also very good."
"."< br>
The experts looked excited and discussed for a long time, and finally gave their acceptance opinions.
Putting aside the clichés, here are a few core points.
The ESR process improvement research of the third steel rolling mill in Beijing 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, further Improved finished product quality.
The improvement and optimization projects such as sliding crystallization, decreasing power control, automatic control of working electrical parameters, and quaternary/five-element low fluorine slag system have advanced design ideas and obvious optimization effects.
In summary, the ESR process optimization and improvement research project of Beijing No. 3 Steel Rolling Plant passed the acceptance test and was successfully concluded!
When the expert group finished signing and finally read out the acceptance results, the scene was filled with joy.
This project is unlike other projects. Basically, Gao Zhendong was the one who tinkered with it, and the others mainly assisted. Due to the scale, workload, and Gao Zhendong’s own busy schedule, this project was a project in which everyone was deeply involved and contributed a lot.
So the success of this project gives everyone a greater sense of accomplishment.
Of course, Gao Zhendong deserves the most credit. If he had not provided the overall principles, original design of each subsystem, detailed design of the automatic control system, slag system design, Q&A, etc., this project would not have been completed. That's unlikely.
Everyone rushed towards Gao Zhendong, lifted him up and threw him into the air many times.
This is also one of the traditional ways to celebrate.
Director Yang, the general commander of the project, Deputy Director Chen, Deputy Director Li, and several conductors also applauded and shook hands with the experts one by one to express their thanks.
Finally, Gao Zhendong was put down by the excited people before he joined these conductors and enjoyed the joy of success together.
The broadcast room of the factory publicity office also received the notification of the acceptance immediately 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 inferior in weight. Materials 591~593 cannot be publicly publicized. Only ESR has sufficient significance, weight and publicity. of.
"Big good news, big good news. The ESR process improvement and optimization research project, which was actively carried out by our factory with self-raised funds, organized resources, and proactively carried out, passed the project completion and acceptance organized by the 17th Machinery Department this afternoon, and the participating experts"
At the same time, the news of passing the acceptance was immediately sent back to the 17th Machinery Department by the staff of the 17th Machinery Department on site. The leader asked him to notify him as soon as possible if the results were found.
This is not an exaggeration. Anyone who knows the history of scientific research at that time will know that technology was lacking at that time. It is normal for this kind of news to alarm the leaders of the 17th Machinery Department.
Unlike Gao Zhendong’s previous life, even people from the Municipal Science and Technology Bureau might not care about something of this level.
The leader laughed heartily when he received the news.
He is not only happy about the success of this scientific research project, but also that it proves that the third steel rolling mill has officially completed the entire process of a scientific research project in a collective form. This is more meaningful to the third steel rolling mill than the ESR improvement itself. Still significant.
As the saying goes, "A single flower does not mean spring, but a hundred flowers bloom and the whole garden is full of spring."
If previous projects can only prove the excellence of Gao Zhendong alone, then the successful improvement of ESR proves that the third rolling mill has initially possessed the ability and conditions for innovation.
Those who have gone through the whole process completely and those who have not gone through it are completely different in terms of their working ideas, working methods and self-confidence.
Just like the war eagle in the sky, it takes decades to fully understand a Qiye, but the transition from Raptor to Veyron is getting faster and faster. This 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 returned to the office: "The conditions are now ripe for what I told you last time. You can report it."< br>
——
At the same time, Chief Engineer Chi of the Computing Center, who had been itching all day and night, finally received the news that the equipment commissioned by Director Gao was completed.
He immediately called Gao Zhendong's factory: "Please convey to Director Gao Zhendong that we have already processed the drawings he sent. Please come over as soon as possible to check and accept them."
After putting down the phone, Chief Engineer Chi felt unhappy: "This third rolling mill is so stingy that they can't even bear to install a phone in Director Gao's office."
When Gao Zhendong received the news, it was already getting off work in the afternoon. , In fact, he was itching in his heart. He already had the recorder and the read and write driver had been written. What was missing was the analog-to-digital conversion equipment.
Thinking of this, he ran to the factory office first and called Mr. Chi: "Mr. Chi, are the things ready?"
"It's done, it's done, it's ready. Why don't you come over and check it out?"
"It's almost time to get off work. I'm here to disturb your rest."
"It doesn't matter, it doesn't matter, it's all for work."
The two anxious people hit it off immediately, and immediately decided that Chief Engineer Chi would wait for Gao Zhendong with his people at the computing office, and Gao Zhendong would go there immediately.
Gao Zhendong took one of the two tape recorders he brought to the computer room and rode towards the computer lab.
After dinner time, the eager Engineer Chi waited until Gao Zhendong arrived. However, he suppressed his strong curiosity and ate first.
He estimated that Gao Zhendong had not eaten when he came over. He had prepared everything in the cafeteria, and he and the staff were waiting for Gao Zhendong to come over and eat together.
A group of people didn't say much, they were very familiar with each other and there was no need to say much.
Everyone put the rice into their mouths and went straight to the computer room. According to Gao Zhendong's request, several analog-to-digital conversion equipment were there.
When Gao Zhendong arrived, he saw that the equipment, required wires, and connectors were all ready. Even the wires and connectors were welded directly according to the line 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 is this? They recognized the two speakers on both sides, but they had no idea what the small box in the middle was covered with a transparent plastic plate.
Gao Zhendong played a trick and put in a useless music tape. Listening to the melodious music, the staff of the computing center were dumbfounded. This thing is so rare, I really want it.
Director Li and Chief Engineer Chi were also stupid, but the reasons for their stupidity were different.
Director Li looked at Gao Zhendong and asked hesitantly: "Director Gao, this thing is good, very good. It is much more portable for listening to music than a record player. I want to get one, but What does this thing have to do with computers? "
Chief Engineer Chi didn't say anything. He just looked at Gao Zhendong. It was obvious that he had the same question.
Gao Zhendong said with a smile: "Director Li, Chief Engineer Chi, what do you think this thing is used to record music?"
The two shook their heads and couldn't tell. The tape is not in a transparent box, and you cannot see the wound tape. There is only a short strip leaking from the top, and nothing can be seen.
However, Mr. Chi has a better association: "Punched paper tape?"
Gao Zhendong smiled and said: "Mr. Chi is great, it's a bit close. This is a music signal recorded on a tape."
When the word "magnetic" was mentioned, Li and Chi suddenly realized what the magnetic drums and magnetic cores were for, recording data!
Mr. Chi asked: "Director Gao, is this used to store data? So small? So light?"
The dual-speaker recorder is actually not too big, although it is small. The rendering is not perfect yet, but it is only about 30*15*8cm.
In the eyes of people in Gao Zhendong’s previous life, this was of course very big, but compared with the transistor memories on several layers of 0.5*0.5 meter boards next to it, and the cabinets of magnetic core memories in the cabinets next to it, it was completely small and exquisite. Lightweight and portable.
Gao Zhendong smiled and nodded: "This thing was given to me by my prospective father-in-law. It was originally used to listen to music. It uses magnetic signal storage and outputs analog audio signals. But when I think about it, , the magnetic signal of this thing is maintained when power is turned off, and it is convenient and portable. Isn't it just right for storing data? I spent some time to create a conversion circuit and wrote a read and write program. If it can be realized, then we will have a portable device. Move the data storage.”
Take a moment and say a few words that make people in the computing center jump.
Portable mobile storage!
Director Li and Chief Engineer Chi suddenly became excited.
10,000 completed.
