Chapter 135 NF Steel Cracked! (4k)

As soon as these words came out, everyone around became nervous.

Gao Zhendong was not in a hurry: "Why rush? It would be strange if there were no problems with the first furnace. Tell me more details."

When everyone heard this, they said, yes, this is the first batch, so there’s nothing to worry about.

Besides, the tests conducted at the Beijing Steel Plant have shown that at least there are no problems with the mechanical and environmental tolerance. At least the first step has been successful, so there is no need to panic.

Director Gao is still here, why are you in such a hurry?

Thinking of this, people couldn't help but secretly praise Director Gao for his composure. As a person who came back from the battlefield, he was indeed able to remain calm in the face of major events.

In fact, it was not entirely because of Gao Zhendong's calmness, but because he knew that there would definitely be problems with this batch of steel when it reached the rolling stage.

After refining, there were still a few steps that were not added in. This was intentional by Gao Zhendong.

It’s not because Gao Zhendong wanted to hide something on purpose, but if the standard was met in just one batch of steel, then this matter would be difficult to explain.

Being too magical is not a good thing, and it is not a bad thing to lower people's expectations of themselves.

If it is really refined in one furnace, everyone will praise it crazily and then give it the nickname "Gao Yilu". It seems to be a good thing, but it is not.

As for whether this is a waste of resources? That's nonsense. Without Gao Zhendong, there would be no chance to waste this resource within 20 years, or it would be a waste of resources for 20 years.

Choose between scrapping a few furnaces and scrapping them for decades.

Besides, this is not a complete waste. It is common to recycle scrap steel to produce new steel. In Gao Zhendong's previous life, when nickel was out of stock, scrap steel was used to ensure the production of nickel-containing steel.

Hearing Gao Zhendong's calm tone, the person who came to report the news from the Third Steel Rolling Mill also calmed down and reported: "Director Gao, cracks appeared on the surface of the initial rolled billet, resulting in a very low yield rate of the final plate."

Is there a problem with thermoplasticity? The yield rate is low.

Everyone can rest assured. The low yield rate means that the product can still be produced. At least based on the data from Beijing Steel Plant, the direction is still correct.

It's amazing that steel can be refined to this level in one furnace.

So everyone felt a lot more relaxed and looked at Gao Zhendong.

Gao Zhendong asked the comrade who came over from the Third Rolling Mill: "Have you come to get the samples?"

The comrade nodded: "I have taken it."

Gao Zhendong turned to the comrades from Jinggang Plant and said, "Please ask the comrades from Jinggang Plant to take him to the laboratory now and use the samples he brought to do an X-ray micro-area analysis. Do an X-ray analysis of the crack, the non-crack static area, and the transition area. Bring the results to see when they come out."

The X-ray microanalyzer was the first instrument produced by the Russians in the north to analyze the composition of a small area of ​​solid matter using X-rays. Although it did not incorporate scanning electron microscopy like the later EPMA (electron probe X-ray microanalyzer), it was already an advanced method at that time and also served as a good reference.

This is the advantage of having Beijing Iron and Steel as a backing. In this regard, their instruments and equipment are more complete than those of the Third Steel Rolling Mill.

After the X-ray micro-area analysis was completed, the comrades from Beijing Steel Plant quickly brought the data. Gao Zhendong took a look at it himself first, and then handed it to the relevant technical personnel from the Third Rolling Plant and Beijing Steel Plant: "Everyone take a look."

Everyone has taken a look. They are all veterans in this industry, so it’s not that they can’t even understand the data.

After everyone finished reading, Gao Zhendong smiled and said, "Everyone, tell us what you think."

So everyone started to communicate with each other in a few words.

"The content of harmful elements in some transition zones is a bit high."

"That's nothing. Look at the cracks. That's high. Look at the sulfur and oxygen."

“The non-cracked static area is essentially invisible.”

"Then it seems that sulfur and oxygen are the cause of the trouble. Just reduce them."

"Lower it further? How? Under the AOD process, it's now around one in ten thousand, almost below the detection limit, and the instrument can hardly detect it."

"It's a bit troublesome. Let's think about what else to add besides argon and oxygen to remove the oxygen and sulfur."

"It's difficult. Argon-oxygen refining requires blowing oxygen."

Everyone offered suggestions and discussed for a long time, but still couldn't come up with a solution. For a moment, no one could think of what to add to the argon oxygen so as to further reduce the already low levels of oxygen and sulfur.

Finally, everyone turned their eyes to Gao Zhendong.

In fact, to solve this problem, leaving aside the principle and only talking about the method, two means must be used in the process.

First, strictly control the temperature throughout the process.

The second is to add something when pouring steel.

It's that simple.

Gao Zhendong had already arranged to control the temperature throughout the entire process when he first began to make the process requirements.

What Gao Zhendong needs to make up for now is the second shortcoming.

Seeing that everyone was focusing on blowing gas, Gao Zhendong smiled and said, "Don't always think about blowing gas. Desulfurization and deoxidation can be processed after refining. For example, when tapping steel, try adding xx kg of Si-Ca blocks and xx kg of Fe-B with the steel flow."

Forced desulfurization and deoxygenation?

When everyone thought of this, they couldn't help but curse themselves for being unable to move forward when seeing the new process. Isn't forced deoxidation a traditional method when tapping steel? They just forgot about it.

This is also a common problem for many people engaged in technology. They pursue technology for the sake of technology. When they see that the so-called high-tech is not working, they throw aside many practical, simple and low-cost technical means.

In fact, many so-called high-tech technologies are just old technologies in a new package.

There is no other way. If we don’t package it and talk about some high-tech stuff, we won’t be able to tell a story and it won’t sell at a high price.

In his previous life, Gao Zhendong’s teacher reviewed a big data project. After peeling off the packaging, it turned out to be a mining machinery, and the actual research content had nothing to do with big data.

This incident became a laughing stock in their circle for a while.

It’s not that we look down on mining machinery, mining machinery is equally important, but I really feel dumbfounded by this phenomenon.

Everyone who was taught a lesson by Gao Zhendong couldn't help but admire him. It was Director Gao who firmly grasped the essence of technology and used whatever was useful.

After receiving Gao Zhendong's clear direction for improvement, everyone quickly got busy. This is how research projects work - we are not afraid of being slow, but we are afraid of standing still.

The comrades from the Third Steel Rolling Mill who rushed over to report the news, seeing that the problem had a clear solution, also prepared to go back.

Before leaving, the comrades from the Beijing Steel Plant reminded us: "Comrades, remember to bring back the cracked scrap steel. It contains high levels of nickel, chromium, and molybdenum, and we can still use it."

While everyone was busy preparing to refine the second batch of NF steel, Lao Chen was reporting the good news to the general manager.

Yes, it is good news. Although the yield rate is low, at least the environmental tolerance performance has basically met the requirements.

No matter how low the yield rate is, it is still finished product after all, and some qualified medium and thick plates are still rolled out.

This is the hope, to give them some reassurance first, so that at least they can continue their work on this technical route with peace of mind.

Otherwise, it would be a pity if they could not continue because the materials needed for the mass production of their research results were hopeless, or if they had to start all over again, wasting time and money.

This time, the factory reimbursed the telegram fee, so Lao Chen felt much more generous.

For the sake of speed, and because the message was quite detailed and somewhat sensitive, it was sent through the confidential and expedited channel. Therefore, the telegram received by President Xiang was much more detailed.

The gist of it is that you are now more confident about the material you want. Our department has personally arranged for our factory to cooperate with Beijing Iron and Steel Plant to trial-produce the first batch of NF material you need. Although there are still some problems with the material during the initial trial production, the approach is correct, and we have rolled out some of the plates you need. After testing, the performance basically meets your requirements, etc. Some environmental tolerance parameters were also attached to the telegram.

Mr. Xiang was very excited when he received the telegram. He immediately called his team together and held a meeting.

It is both a notification and an encouragement.

The entire team was present. President Xiang held President Chen's telegram and waved it in front of him excitedly: "Comrades, our comrades from the steel plant far away in Beijing have sent us good news. We can continue our research with confidence!"

The entire team was confused and kept whispering to each other, but knowing that this was good news, they were all excited.

President Xiang held the telegram in front of him and read it word by word to his colleagues in the team, even including the laboratory test results of the first batch of NF materials.

As President Xiang spoke word by word, the team members became more and more excited.

Everyone couldn't help but whisper to each other. They couldn't help it, they absolutely couldn't help it.

"Now we can proceed with this with confidence. As long as we stick to this route, this material will work."

"I didn't expect that just one visit to the capital to ask for help would have such an effect."

“I don’t know how hard the steel comrades in Beijing worked to come up with what we need in such a short time.”

"That's great, that's great."

"This mechanical strength has basically met our requirements."

"The yield rate is not very good? The finished product rate is low?"

"Don't worry, this is just the first batch, they are still improving it."

"Even with the current yield rate, it is enough for us to use it for design and demonstration."

"Did you hear those speed parameters? As long as it can be kept stable, we can use it. At worst, we can just increase the redundancy when designing it."

"."

After reading the telegram, General Xiang turned to the comrades and said, "Comrades, is this good news?"

There was a roar from below: “Okay!!”

"Can we live up to the expectations and trust of our comrades in Beijing who are working on materials?"

"cannot!!"

“Do you have the confidence and determination to do this next?”

"Have!!"

“Can we produce the results that our motherland and the people want?”

"able!!"

"Are you going to work overtime tonight?"

"No!" Everyone laughed and felt extremely relaxed.

The atmosphere was warm and morale was high.

To the general team, we are working hard on our own craftsmanship.

Gao Zhendong's team is also constantly testing and adjusting its own technology, preparing to serve the overall team's technology.

Two different teams in two far-flung places are working towards the same goal.
-

The second batch of NF materials has been refined and sent to the third rolling mill for trial rolling.

At this time, a routine work meeting of the 17th Ministry of Machine Building was being held in the conference room of the 17th Ministry of Machine Building.

As the meeting progressed, an agenda item related to the Third Steel Rolling Mill was discussed.

Beijing No. 3 Steel Rolling Mill's "Application for Upgrading the Technical Section of Our Factory to a Technical Department".

Secretary Zheng distributed the photocopies to each participant, and they all looked at them carefully.

Seeing that everyone had seen it, the leader said, "Now that everyone has seen it, tell us what you think."

"It's a good thing. The mismatch between the technical strength of the Third Steel Rolling Mill and its scale should have been resolved long ago."

"They have indeed achieved great success recently, but isn't their technical strength too concentrated?" The implication is that their technical strength is too concentrated in a few people.

"I don't think it's a big problem. I've read their ESR and it's a collective effort, fully mobilizing the masses."

"ESR has indeed trained a good team for them. It would be a shame not to make use of it."

"Now their teams have all gone to the Jingcheng Steel Plant to play a role. Yesterday, we received a joint application from the Jingcheng Steel Plant and the Third Steel Rolling Mill to develop a new steelmaking process."

"That's good, but isn't this a bit too much? It's just adding a department and several sections out of thin air."

Hearing this, the leader coughed and said, "Tell me what I think."

Everyone stopped and waited for him to speak.

"The recent achievements of the Third Steel Rolling Mill have undoubtedly met the requirements for upgrading."

"But obviously, they also have shortcomings. There are only a few comrades with strong technical abilities, and their overall ability is not enough."

"Fortunately, the comrades of the Third Steel Rolling Plant quickly realized this problem and intentionally trained the team and built up combat effectiveness in scientific research projects such as ESR. Judging from the results of ESR, the scientific research strength of their team has generally been improved."

"Moreover, apart from scientific research, the Third Steel Rolling Mill also needs a technical team that matches the scale of their enterprise to support their daily production."

"From this perspective, even if we don't consider the scientific research issues of the third steel rolling mill, this issue must be resolved."

After hearing the leader's words, everyone's thoughts began to change.

Hey, it’s not a big deal, just a problem with a virgin. At their level, it’s not a small thing, but it’s not a big thing either.

Moreover, the Third Steel Rolling Mill has indeed been making great progress recently and has achieved remarkable results, so any upgrade is justified.

"Well, the Third Steel Rolling Mill does need to expand its technical team. We can't fall into the vicious circle of low level so small scale, small scale so weak strength, weak strength so no achievements, no achievements so low level."

"The Third Steel Rolling Mill has been very successful in the past, using relatively small technical forces to support such a large-scale production. Now that the conditions are ripe, we can't let the honest people suffer losses all the time."

"If there is a shortage of manpower, we can transfer some people over."

When the leader heard this, he smiled and said, "We won't transfer people for the time being. All enterprises are in a difficult situation. Let's tap the potential within the Third Rolling Mill."

After saying that, he looked around at everyone and made the final decision: "If everyone has no objection, then this matter is settled."

Passed unanimously.
