Chapter 135 NF steel cracked! (4k)
As soon as this sentence came out, everyone around him was very nervous.
Gao Zhendong was not in a hurry: "What's the hurry? It would be strange if there was no problem in the first furnace. Let's talk about it in detail."
When everyone heard it, yes, this special It's the first furnace, then it's okay.
Besides, the tests at the Beijing Steel Plant have shown that at least the mechanical and environmental tolerance is no problem, and at least the first step has been successful, so panic.
Director Gao is still here, why are you so anxious?
Thinking of this, people couldn't help but secretly praise that Director Gao was still able to keep his composure. People who came down from the battlefield were indeed calm when faced with major events.
In fact, it is not entirely because of Gao Zhendong's calmness, but because he knows that there will definitely be problems with this furnace of steel when it reaches the rolling stage.
After refining, there are still a few links that have not been added. This is Gao Zhendong’s intention.
It’s not because Gao Zhendong wanted to hide his secret, but because he really met the standard with just one blast of steel, so it’s hard to explain this.
Being too magical is not a good thing, and lowering people's expectations of themselves appropriately is not a bad thing.
It was really made in one furnace, and everyone praised it wildly, and then gave it the nickname "Higher in one furnace". It seemed like a good thing, but in fact it was not.
As for whether this is a waste of resources? No matter what, without Gao Zhendong, there would be no chance to waste this resource within twenty years, or in other words, resources would have been wasted for twenty years.
Waste a few furnaces or waste it for decades, choose one.
Besides, this is not completely wasteful. It is a common thing to use scrap steel to produce new steel. In Gao Zhendong’s previous life, when nickel was cut off, scrap steel was used to basically 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 Plant also calmed down and reported: "Director Gao, cracks appeared on the surface of the rough rolling blank, resulting in a very low yield rate of the final plate."
Problems with thermoplasticity? The yield rate is low.
Everyone, please relax a little. The low yield rate shows that it can still be finished. At least based on the data from Beijing Steel Plant, the path is still in the right direction.
It’s amazing to be able to refine steel to this level in just one furnace, okay?
So everyone felt a lot more relaxed and looked at Gao Zhendong.
Gao Zhendong said to the comrades who came from the third rolling mill: "Have you come to take the samples?"
The comrade nodded: "I have taken them."
Gao Zhendong turned to the Beijing Steel Plant The comrade said: "Please take the comrades from the Beijing Steel Plant to the laboratory now and use the samples he brought to do an X-ray micro-area analysis. Do one inside the crack, the non-crack static area, and the transition area. The results are out Let’s take a look.”
The X-ray Micro Analyzer is an instrument first produced by Beibian Da Maozi that uses X-rays to analyze the composition of tiny areas of solid matter. Although it has not yet incorporated scanning electron microscopy imaging like the EPMA (Electron Probe X-ray Microanalyzer) in the future, at this time, it is already an advanced method and serves as a good reference.
This is the advantage of being backed by Beijing Iron and Steel Co., Ltd. In this regard, their instruments and equipment are more complete than those of the third rolling mill.
After the X-ray micro-area analysis was completed, the comrades from the Beijing Steel Plant quickly brought the data. Gao Zhendong read it himself first, and then handed it over to the relevant technical personnel of the No. 3 Rolling Plant and the Beijing Steel Plant: "Everyone, take a look. . ”
Everyone looked at it, they are all veterans in this industry, so they can’t even figure out the data.
After everyone finished reading, Gao Zhendong smiled and said, "Let's talk about your thoughts."
So everyone started to communicate in a few words.
“The content of harmful elements in some transition zones is a bit high.”
"That's nothing. Look at the crack part. That's high. Look at the sulfur and oxygen."
"The non-crack static area is basically invisible."
"Look at it. It’s sulfur and oxygen that are causing trouble. Just lower it.”
“How to lower it? With the AOD process, it is now about 1/10,000, almost below the detection limit, and the instrument is almost there. It can’t be detected.”
“It’s a bit troublesome. Let’s think about adding something besides argon and oxygen to remove the oxygen and sulfur.”
"It's difficult. Argon-oxygen refining originally requires blowing oxygen."
Everyone came up with ideas one after another and discussed it for a long time, but they still couldn't come up with a way. For a while, they couldn't think of adding argon-oxygen to it. What can further reduce oxygen and sulfur to already very low levels?
In the end, everyone turned their eyes to Gao Zhendong.
In fact, to solve this problem, let’s put aside the principle and only talk about the method. Two methods must be used in the process.
First, strictly control the temperature throughout the entire process.
The second is to add something when tapping the steel.
It’s that simple.
Control the temperature throughout the entire process. Gao Zhendong had already made arrangements when he first met the process requirements.
Now what Gao Zhendong wants to make up for is the second shortcoming.
Seeing that everyone was making a fuss about blowing gas, Gao Zhendong smiled: "Don't always think about blowing gas. Desulfurization and deoxygenation can also be processed after refining. In this way, try to When tapping steel, add xx kg Si-Ca block and add xx kg Fe-B along with the steel flow.”
Forced desulfurization and deoxygenation?
When everyone thinks of this, they can’t help but secretly curse themselves for being unable to walk after seeing the new process. Isn’t forced deoxidation a traditional method when tapping steel? This was forgotten.
This is also a common problem among many people who are engaged in technology. They pursue technology for the sake of technology. When they see that so-called high-tech cannot work, they throw aside many practical, simple and low-cost technical means.
In fact, many so-called high technologies are just old technologies repackaged in new shells.
There is no other way. If you don’t package it and use some high technology, you can’t tell a story and you can’t sell it at a high price.
In a previous life, Gao Zhendong's teacher reviewed a big data project. After peeling off the packaging, it was actually a mining machine, and the actual research content had nothing to do with big data.
This matter became a joke among their circles for a while.
It’s not that I look down on mining machinery, which is equally important, but I really don’t know whether to laugh or cry about this phenomenon.
Everyone who was taught a lesson by Gao Zhendong couldn't help but admire him. Director Gao must firmly grasp the essence of technology and use whatever is easy to use.
After Gao Zhendong’s clear direction for improvement, everyone quickly got busy. This is the case with research projects. Don’t be afraid of being slow, just be afraid of standing still.
The comrades from the Third Steel Rolling Plant who rushed over to report the problem saw that they had a clear solution to the problem and were ready to go back.
Before leaving, the comrades from the Beijing Steel Plant did not forget to remind: "Comrade, remember to transport the cracked scrap steel back. The nickel, chromium and molybdenum in it are quite high, and we can still use it."
While everyone was in full swing 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 resistance performance has basically caught up with the requirements.
No matter how low the yield rate is, it is still finished after all. There are still some qualified medium and thick plates rolled out.
This is the hope, to give them some reassurance first, so that they can at least continue their work on this technical route with peace of mind.
Otherwise, it would be a pity if they could not continue the process because the materials required for the mass production process of their research results were hopeless, or they would waste time and money by starting a new one.
This time, the telegraph fee was reimbursed by the factory, and Lao Chen felt much more heroic.
For the sake of speed, and being more detailed and somewhat sensitive, I took the confidential expedited channel. Therefore, the telegram received by President Xiang was much more detailed.
The general idea is that we are now more certain of the materials you want. Our ministry has personally deployed it, and our factory has teamed up with the Beijing Steel Plant to trial-produce the first batch of the NF materials you need. Although there are still some problems with the materials during the initial trial production, the method is right and some of the plates you need have been rolled. After inspection, the performance basically meets your requirements. Some environmental tolerance parameters were attached with the telegram.
Mr. Xiang was very excited after receiving the telegram. He quickly summoned his team and held a meeting immediately.
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 with excitement: "Comrades, our comrades from the steel factory in the capital have conveyed to us Here’s the good news, we can proceed with our research with confidence!”
The whole team didn’t know what was going on, so they whispered to each other, but knowing that this was good news, they were all excited.
Mr. Xiang held the telegram in front of his eyes and read it word for word to the comrades in the team. He even did not miss the laboratory test results of the first batch of NF materials.
As President Xiang’s voice fell word by word, the comrades in the team became more and more excited.
Everyone couldn't help but whisper to each other. They couldn't help it, they couldn't help it at all.
“Now we can proceed with peace of mind. As long as we continue to follow this route, this material will be effective.” It works.”
“I don’t know how hard the comrades working in the steel industry in Beijing have worked so hard to come up with what we need in such a short period of time.”
“That’s great, great.”
"This mechanical strength has basically met our requirements."
"The yield is not very good? The yield is low?"
"Don't be afraid, they are just the first batch, aren't they still there? Improvement”
"Even with the current yield rate, it's enough for us to use it for design and demonstration first."
"Did you hear those speed parameters? As long as they can be stabilized, we can use them. At worst, we can't use them during design. Make the redundancy bigger."
"."
After reading the telegram, President Xiang said to the comrades: "Comrades, is this good news?"
There was a roar below: "Okay!!"
"Can we live up to the expectations and trust of the comrades who are working on materials in Beijing?"
"No!!"
"Do we have the confidence and determination to go forward?"
"Yes!!"
"Can we produce the results that the motherland and the people want?"
"Yes!!"
"Will you work overtime tonight?"
"No!" Everyone burst into laughter and felt extremely relaxed.
The atmosphere was warm and the morale was high.
The general team is working hard to study their own craftsmanship.
Gao Zhendong's team is also constantly testing and adjusting its own processes, preparing to serve the general team's processes.
Two different teams in two places, working hard for the same goal.
——
The second batch of NF material has been refined and sent to the third rolling mill for trial rolling.
At this time, the regular work meeting of the 17th Machinery Department was being held in the conference room of the 17th Machinery Department.
As the meeting progressed, an agenda item related to the third rolling mill was reached.
Beijing No. 3 Steel Rolling Plant "About the application for upgrading the technical department of our factory to the technical department".
Secretary Zheng sent the photocopies to all the participants one by one, and they all looked at them carefully.
Seeing that everyone had seen it almost, the leader said: "Everyone has seen it, let's talk about your opinions."
"The thing is a good thing. The technical strength and strength of the third rolling mill are The mismatch in enterprise size should have been resolved long ago.”
"They have indeed had good news recently, but their technical strength is too concentrated." The implication is that it is all concentrated on a few people.
"I don't think it's a big problem. I've seen ESR, and they still work together to fully mobilize the masses."
"ESR has indeed trained a good team for them. If they don't take advantage of it, It’s a pity.”
“Now their team has gone to the Jingcheng Iron and Steel Plant to play a role. Yesterday, they received a joint application from the Jingcheng Iron and Steel Plant and the Third Steel Rolling Plant to develop a new steelmaking process. . ”
“That’s good, but does this establishment require too much? Just create one more department and several departments out of thin air.”
Hearing this, the leader coughed: "Let me tell you my opinion."
Everyone stopped and waited for him to speak.
“The third rolling mill has recently met this upgrade requirement in terms of results.”
“But it is obvious that they also have shortcomings and strong technical capabilities. There are only a few comrades, and the overall ability is not enough.”
“Fortunately, the comrades of the No. 3 Steel Rolling Plant quickly realized this problem and deliberately trained the team to build 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 work, the third rolling mill also needs a technical team that matches the scale of their enterprise to support their daily production."
"From this perspective, even if Let’s not consider the scientific research issue of the third steel rolling mill. This matter must be solved.”
After hearing the leader’s words, everyone’s minds started to change.
Hey, what a big thing, a problem in one place, at their level, it is not small at all, but it is not big at all.
And the No. 3 Steel Rolling Plant has been receiving good news frequently recently, with dazzling results. No matter how high it is, it makes sense.
"Well, the third rolling mill does need to expand its technical team. It cannot fall into the trap of low level so it is small in scale, small in scale so it is weak, weak in power so it has no achievements, and it has no achievements so it is low in level."
" The Third Rolling Mill has carried forward its style and supported such a production scale with a relatively small technical force. Now that the conditions are mature, we cannot always let honest people suffer. "
"If there is not enough manpower, it can still be done. It’s appropriate to transfer some people.”
Hearing this, the leader said with a smile: “I won’t transfer people for the time being. It’s very difficult for all companies. Let’s tap the potential within the third rolling mill.”
After finishing speaking, he looked around at everyone and made a final decision: "If everyone has no objections, then this matter will be settled."
Passed unanimously.
