Chapter 598 This line is too high

He has made a move into fertilizers, and now it's time for him to make a move into steel as well.

Unlike ESR, AOD, specific steel grades and alloy materials, this time, he plans to write his name into the process manuals of all steel mills.

And there is an advantage to doing this, which is that it has nothing to do with what happened before, and he doesn't have to mention this matter, because this result will attract everyone's attention.

He coughed lightly, cleared his throat, and raised his head.

Seeing this, the comrades at the scene all had similar thoughts.

He smiled and said, "Thank you, leaders, and thank you all comrades. I learned a lot just now."

What nonsense are you talking about? It doesn't matter how much you have learned. What matters now is what you have to say. Seeing his unhurried manner, his comrades wished they could snatch the words directly from his mouth.

There is no way, this person is too famous in the 17th Ministry of Machine Building system.

"As for the steel quality issue, you all have made many good comments and suggestions just now. I will not repeat them to avoid wasting your time."

Look, they simply don't bother to rehash other people's old ideas. If they want to do something, they'd rather do something new.

"What I am thinking about is how to further improve product quality from the source of quality - production, and control as many problems as possible in the production link that directly affects quality, reduce the workload of quality management, and improve production and management efficiency."

It’s different, it’s different. Once we take action, we go straight to the root of the problem. The system is very important, but I want to reduce the pressure on the system.

"I have been thinking about this work and have been doing it all the time. It requires a lot of data and time. Fortunately, I have finally achieved some results recently."

That’s enough, Chief Engineer Gao, you’ve laid enough groundwork. If you have any good stuff, please bring it out.

This is what everyone wants, and the leaders are also very interested in it. Gao Zhendong rarely has such a long opening speech and foreshadowing.

Having said that, Gao Zhendong stood up, walked to the blackboard in the meeting room, and began to draw on it.

This picture is actually quite simple, with a coordinate system, a straight line with a relatively large inclination, and then several dotted lines and several points marking some special places.

After Gao Zhendong finished drawing this picture, he turned around and looked at everyone, and said the words that everyone had been waiting for for a long time.

“I call it the blast furnace operating line!”

It can also be called the Gallic operating line, Gao Zhendong thought to himself, because this line actually came from Rist, a metallurgical expert from Gallia, and was proposed in the mid-60s.

I'm sorry, for the sake of the happiness of our people, I have to accept this Rist line. We are all from the Gaul family, and I think the Gauls won't mind.

The whole audience was silent. Well, mainly because they didn't understand. If the Rist line wasn't explained, most people wouldn't understand it. It's not because it's complicated, but on the contrary, the way it's presented is quite simple, even too simple.

However, when we hear the words "blast furnace operating line", we all know the significance of this line. The blast furnace has good economic indicators, simple process, large production volume, high labor productivity and low energy consumption. It is the main production process for bulk steel grades.

Being able to provide guidance on the operation of blast furnaces, for the people in the 17th Ministry of Machine Building, every one of you here is within the scope of this line.

Everyone's eyes were fixed on Gao Zhendong, with the same expression: "Chief Engineer Gao, please explain quickly!"

It can be said that if Gao Zhendong throws away the chalk and wants to turn around and walk out of the meeting room now, he will definitely not be able to walk out. He will definitely be pushed back to the blackboard and will not be allowed to leave until he finishes speaking!
You want to run away after showing off? It's not that easy.

Seeing that everyone's patience had reached its limit, Gao Zhendong, who had successfully pretended to be cool, turned around and began to explain to everyone the Gaul... no, the blast furnace operation line.

The Rist line is actually very simple to explain. Rist attributes the blast furnace smelting process to a process of oxygen migration through carbon (CO, CO2). This migration process, which is closely related to the (Fe-OC) ternary system, is depicted with a straight line in a plane rectangular coordinate system, and combined with the heat balance of the high temperature zone of the blast furnace, the blast furnace operating line is obtained.

This line can guide the production of all types of steel in the blast furnace and improve the smelting process. It has guiding significance for the feeding of coal and oxygen in the smelting process, the steelmaking process, the sequence, etc.

In the earliest steelmaking work, when to add materials, how much to add, etc., mainly relied on intuitive observation, such as the furnace top temperature, the CO and CO2 content in the furnace top gas, etc. This kind of observation, even if the specific values ​​are known, is still a kind of intuitive observation with limited guiding significance, and it feels a bit like hindsight. Temperature changes and reaction products all require a process.

Later, things got better and we were able to perform simple calculations, such as fuel ratio, coke ratio, and so on. This provided some guidance for the material input, but such calculations were extremely simple, and steelmaking is a dynamic process.

Later, it was possible to calculate certain parameters related to the steelmaking process through methods such as material balance, heat balance, and direct reduction degree, but the calculations of these methods were very complicated.

The characteristic of Rist blast furnace operation line is that it is really simple and not complicated to use, but it can directly express the changes of Fe-OC system and the internal connection between various production indicators in the blast furnace smelting process. It is very convenient for the analysis and operation of the smelting production process and is a cost-effective method.

It can not only provide guidance for the production of existing blast furnaces, but also provide a design basis for the design, selection and power balance of new blast furnaces. Moreover, this line can directly participate in automatic control because it is a simple model, even if it is relatively static, it is still a model that can provide certain guidance for dynamic processes.

This "simple" is a compliment, not an insult. Those who work in control would like the control algorithm to be as simple as possible. If there is a way, who would be willing to come up with something extremely complicated?

After listening to Gao Zhendong’s introduction, everyone was excited, especially the leaders of the 17th Ministry of Machine Building.

If Gao Zhendong had solved problems in a specific direction before, this time he directly launched a real big satellite and solved a fundamental problem in the entire metallurgical industry.

Compared with specific steel grades, Gao Zhendong's move directly solved the production guidance problem of bulk steel grades, which is of great significance to product quality, energy consumption, cost, process improvement, etc.

No wonder Gao Zhendong said that a lot of data and analysis are needed. The simplest thing is the best. The simpler something looks, the more effort is behind it.

Who the hell said Gao Zhendong didn't care much about the affairs of our Seventeenth Machinery Department? That was when he was busy, you didn't see it!

At this time, the leaders of the 17th Ministry of Machine Building were grateful that they had provided Gao Zhendong with full freedom in his work and had given him the green light in every sense.

Comrade Gao Zhendong, you can do whatever you want, I will never interfere!

Don’t get excited yet, don’t get excited. This is just an introduction. You have to listen to the content to know. At least you will know whether it is reliable or not after listening to the content.

The leader suppressed his emotions. Even though he knew Gao Zhendong never fought a battle without confidence and never did unreliable things, he still suppressed his emotions because this matter was too big.

While everyone was excited, they all held the same mentality: stay calm, stay calm.

Gao Zhendong gave a detailed explanation of the blast furnace operation line, including how to establish the coordinate system, how to draw this line, what each segment represents, how to calculate and transform various indicators through this line, etc.

The more he spoke, the brighter the eyes of the comrades below became, until finally they even became fanatical.

"This thing is great. Compared to using the rd-C (Pavlov's direct reduction degree of iron and carbon consumption diagram) line, this is much simpler in calculation, but the results are richer and more meaningful. Good! Really good!"

These are the words of the chief engineer of the 17th Machine Department. As the person at the top of the technical pyramid in the industry, he compared the blast furnace operating line with the most advanced analysis method.

Simple, convenient, and effective! This simple straight line is so exaggerated!
He has this attitude, let alone others.

As Gao Zhendong spoke, all the comrades below were also paying close attention and taking notes. If anyone came in and disturbed them now, it would be a big joke.

If anyone saw this scene, they probably would not believe that the top technical and management personnel from the Seventeenth Ministry of Machine Building in the conference room would study as seriously as primary school students.

Finally, Gao Zhendong finished his last word, threw the chalk aside, and patted the chalk dust off his hands.

"These are my ideas. I hope they can bring benefits to the efficiency, quality, energy consumption and cost of steel production. Thank you for listening to me for so long."

Everyone was still a little reluctant to leave, and it took a long time for them to realize that this feast for the metallurgical industry was over.

The leader of the 17th Ministry of Machine Building was the first to stand up, followed by the chief engineer, the third, the fourth...

The leader looked at Gao Zhendong who was standing by the blackboard and said, "Thank you, Comrade Gao Zhendong!"

After saying that, he began to clap his hands vigorously.

"Clap clap clap..."

“Pah, pah, hua…”

"Whoa, whoa, whoa, whoosh..."

The comrades who had just escaped from the "small technical shock" gradually came to their senses under the influence of the leadership's applause. The applause became increasingly frequent and from small to large, and lasted for a long time.

After a long while, the leader made his first suggestion: "Comrades, how about we call this line the Gao's Operation Line?"

"Okay!~~~~~" Everyone responded loudly. This title should be his!
Gao Zhendong waved his hands repeatedly: "No, no." Mainly because he was afraid that Mr. Rist would be mad to death. Besides, personal endorsement is not necessarily a good thing these days.

The leader looked at him seriously and said, "Comrade Gao Zhendong, it is right to name major achievements after the working people and scientific and technological workers!"
