Chapter 598: This line has a high surname
He has had a hand in chemical fertilizers, and now it is time to have a hand in steel.
Different from ESR, AOD, specific steel types and alloy materials, this time, he plans to write his name into the process manuals of all steelmaking plants.
And the advantage of doing this is that it has nothing to do with what happened before, and he doesn't need to mention it, because this result will attract everyone's attention.
He coughed slightly, cleared his throat, and raised his head.
One look at this posture, oh, Chief Engineer Gao is going to go big! Similar thoughts came to mind among the comrades present.
He smiled and said: "Thank you, the leader, 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, the comrades wanted to take the words out of his mouth.
There is no way, this person is really famous in the 17th Machine Department system.
"As for the issue of steel quality, all comrades have just put forward many good opinions and suggestions. If they are repeated, I will not say them again, so as not to waste everyone's time."
Look, people don't even bother chewing on other people's cold rice. If they want to do something, they will create something new.
“What I’m thinking about is how to further improve product quality from the perspective of production, the source of quality, and control as many problems as possible in production, a link that directly affects quality, so as to reduce the workload of quality management and improve production. and management efficiency.”
It’s different, it’s just 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. It requires a lot of data and time. Fortunately, recently, I have finally achieved some results."
That's enough, Chief Engineer Gao, that's enough preparation. If you have any good stuff, 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 and foreshadowing.
Having said this, Gao Zhendong stood up, walked to the blackboard at the venue, and began to draw pictures on it.
This picture is actually relatively simple, with a coordinate system, a straight line with a relatively large slope, and then a few dotted lines and points marking some special places.
After Gao Zhendong finished drawing this picture, he turned his head to look at everyone and said what everyone had been waiting for.
"I call it the blast furnace operating line!"
It can also be called the Gallic operating line, Gao Zhendong thought in his mind, because this line actually came from Rist, a metallurgical expert from Gaul, who was proposed in the mid-1960s.
Sorry, for the sake of the happiness of our people, I accept this Rist line. Everyone is from the Gao family. I guess the Gauls won't care.
The whole place was silent. Well, the main reason is that they don’t understand. If the Rist line is not explained, most people will not be able to understand it. It is not because it is complicated, but conversely, the expression of this thing is quite simple, even too simple. .
But after hearing the words blast furnace operation line, everyone knows the meaning of this line. Blast furnace has good economic indicators, simple process, large production volume, high labor productivity and low energy consumption. It is the main production process of bulk steel.
To be able to provide guidance on the operation of the blast furnace, for the people of the 17th Machinery Department, not one of them here can escape the field of this line.
Everyone's eyes were fixed on Gao Zhendong, all with the same expression: "General Engineer Gao, please explain!"
It can be said that if Gao Zhendong throws away the chalk and wants to turn around and walk out of this conference room, 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!
Are you pretending to be cool and want to run away? Nothing is that cheap.
Seeing that everyone's patience had reached its limit, Gao Zhendong, who had succeeded in showing off, turned around and began to explain to everyone Gaul... no, the blast furnace operating line.
The Rist line is actually very simple to say. Rist attributes the blast furnace smelting process to a migration process of oxygen through carbon (CO, CO2). This migration process, which is closely related to the (Fe-O-C) ternary system, is described with a straight line in a plane rectangular coordinate system, and combined with the thermal balance in 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 can improve the smelting process. It has guiding significance for the coal and oxygen input 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 It is a kind of intuitive observation, with limited guiding significance, and it is a bit of hindsight. Temperature changes and reaction products all require a process.
Later, it got better and I could perform simple calculations, such as fuel ratio, coke ratio, etc. This gave me some guidance on feeding materials, but this calculation was extremely simple, and steelmaking was a dynamic process.
Later, it was possible to calculate certain parameters related to the steelmaking process through methods such as material balance, heat balance, direct reduction degree, etc., but the calculations of these methods were very complicated.
The characteristic of the Rist blast furnace operation line is that it is really simple and its application is not complicated, but it can directly express the changes in the Fe-O-C system and the internal relationship between the production indicators during the blast furnace smelting process. It is very important for smelting production. The analysis and operation of the process are very convenient, and it is a cost-effective method.
And it can not only guide the production of existing blast furnaces, but also provide 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 and can provide certain guidance for the dynamic process.
This "simplicity" is a compliment, not a disparagement. Those who are involved in control are eager to make the control algorithm as simple as possible. As long as there is a way, who would be willing to come up with a completely complicated thing.
After listening to Gao Zhendong's introduction, everyone was excited, especially the leaders of the 17th Machinery Department.
If Gao Zhendong solved problems in a specific direction before, this time he directly launched a real big satellite and solved a basic problem in the entire metallurgical industry.
Compared with specific steel types, Gao Zhendong directly solved the problem of production guidance for bulk steel types, 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 simpler the thing, the more effort behind it.
Who the hell said that Gao Zhendong didn't care much about the affairs of our 17th Machinery Department? That was when people were busy, and you didn’t fucking see it!
At this time, the leaders of the 17th Machinery Department were grateful that they had provided Gao Zhendong with full freedom and green light in every sense of the word.
Comrade Gao Zhendong, you can do whatever you like and I will never interfere!
Don't be excited or excited yet, this is just an introduction, you have to listen to the content to know, at least listen to the content to know whether it is reliable or not.
The leader suppressed his emotions. Even though he knew that Gao Zhendong never fought uncertainly and never did anything unreliable, he still suppressed his emotions because this matter was too big.
Although everyone was excited, they also held the same mentality, steady, steady.
Gao Zhendong explained in detail the blast furnace operating line, including how to establish the coordinate system, how to draw this line, what each segment means, how to calculate and transform various indicators through this line, etc...< br>
The more he spoke, the brighter the eyes of the comrades below became brighter, and finally even brightened to the point of fanaticism.
"This thing is great. Compared with calculating using the rd-C (Pavlovian Direct Reduction Degree of Iron and Carbon Consumption Diagram) line, this calculation is much simpler, but the results are richer and more meaningful. Good! Really OK! ”
These are the words of the chief engineer of the Seventeenth Machinery Department. As a person at the top of the technology pyramid in the industry, he compared the blast furnace operation 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 said this, all the comrades below were staring intently and remembering that if anyone came in to disturb us now, it would be great fun.
If anyone had seen this scene, they would probably not be able to believe that the top technical and managerial staff of the 17th Machinery Department in the dark conference room would study as seriously as primary school students.
Finally, Gao Zhendong finished speaking the last word, threw the chalk tip aside, and patted the chalk dust on his hand.
"These are my thoughts. I hope it can bring useful things to the efficiency, quality, energy consumption, cost and other aspects of steel production. Thank you, comrades, for listening to me nagging for so long."
Everyone was still a bit unsatisfied, and it took a long time to realize that this gluttonous feast in the metallurgical industry was over.
The leader of the 17th Machinery Department was the first to stand up, followed by the chief engineer, the third, and the fourth...
The leader looked at Gao Zhendong beside the blackboard: "Thank you, Comrade Gao Zhendong!"
After saying that, he started to clap vigorously.
“Pa bang bang…”
"Pa bang wah wah..."
"Hua Hua Hua Hua..."
The comrades who had just escaped from the "little technical shock" gradually came back to their senses, driven by the applause of the leaders. The applause increased from sparse to dense, from small to large, and lasted for a long time.
After a long time, the leader made his first suggestion: "Comrades, let's call this line Gao's operating line, okay?"
"Okay!~~~~~" Everyone responded loudly, this name should be his!
Gao Zhendong waved his hands repeatedly: "I can't do it, I can't do it." Mainly because he was afraid that Mr. Rist would be angry to death. Besides, personally naming someone is not necessarily a good thing these days.
The leader looked at him seriously: "Comrade Gao Zhendong, it is appropriate to name major achievements after the working people and scientific and technological workers!"
