Manganese 01 is put into the third position.
In the next two hours or so, Chen Nuo gave dozens of orders, sometimes only one material at a time, and most of the time the four feeding ports put in materials at the same time, and the longest interval between orders was almost half an hour.
Chen Nuo recorded various data while giving instructions, and various data also jumped out of the laptop.
That's it, pour it into the mold and send it to the condensation chamber.
Another hour passed, and Chen Nuo finally poured out the molten steel from the blast furnace, and sent it directly into the condensation chamber.
Although several professors were puzzled by this unreasonable operation, they still carried it out without any discount.
A few of you have worked hard, just hold on for another hour.
Several professors nodded.
In the next hour, the steel billets sent into the condensation chamber were rotated back and forth between the blast furnace and the condensation chamber three times before they were completely put down.
Ladies and gentlemen, let's eat something and wait for it to cool down completely.
Chen Nuo looked at the red alloy steel inside the die casting, and took off the protective clothing first. After several people took off the protective clothing, water poured out of the protective clothing, and the clothes were all soaked.
The few people who relaxed sat down on the ground, gasping for breath.
The four of them looked at each other, and they all saw the doubt in their eyes.
I have been studying materials for decades, but this is the first time I saw this method of steelmaking, and I didn't understand the whole process at all.
From their point of view, Chen Nuo was not making steel, but fooling around.
If you have to use one to describe it, it is like the ancient alchemist alchemy.
Converter, refining furnace, continuous casting and other equipment are not used.
Come on, let's go see the finished product.
After eating and resting, Chen Nuo took the lead in heading towards the cooled mold.
How can this be?
A professor exclaimed when he saw the alloy steel plate with a length of one meter and a thickness of 10 centimeters.
It's just because the surface of this alloy steel plate is extremely flat, just like a knife cut, it's pitch black with a faint luster.
Under normal circumstances, the surface of this kind of steel that has not passed through the steel rolling production line should be uneven.
Professor Chen, wait a minute!
Seeing that Chen Nuo was about to reach out to touch it, Zhang Shitang was immediately stopped. Although the surface of this high-temperature steel is cooled, the internal temperature is still extremely high, and it is easy to burn.
Zhang Shitang took a small instrument from the side and scanned it on the alloy steel plate. After looking at the numbers on the instrument, he was a little puzzled. Could it be that the instrument is broken?
Lao Gao, change the instrument.
Professor Gao Shizhong next to him immediately took another instrument from the side and handed it over, and the data displayed was exactly the same as the previous one.
It shouldn't be!
Zhang Shitang muttered to himself, a little puzzled.
Chen Nuo sighed. If these people care about it, they will be chaotic. If two instruments in the laboratory of the Chinese Academy of Sciences have problems at the same time, they can close the door.
In the horrified eyes of everyone, the right hand directly pressed the alloy steel plate, the tentacles were warm and moist, without the slightest sense of heat, as if rubbed on a piece of jade.
Try it too!
Chen Nuo turned around to say hello, and several professors pressed their palms on seeing this.
In just an instant, the four of them were stunned, completely different from what they expected.
Chapter 413 The Horror Data of Alloy Steel
How can it be?
The four professors stared at the weight displayed on the weighing machine, dumbfounded.
This steel plate with a length of one meter, a width of one meter, and a thickness of 0.1 meters has 100kg of refined steel put into it, and several alloy materials have been added in front and back. According to their estimation, this steel plate should weigh more than 250kg, but now it is only 135kg.
According to the volume of the steel plate, the density of this steel plate is 1.35g/cm3, only one-fifth of ordinary steel.
Let's go, do other project tests, and try to get the results today.
Metal property tests include hardness, yield strength, high toughness, oxidation resistance, high temperature resistance, no deformation and low temperature resistance, etc.
Each performance test includes many small tests, and there are many test methods. For example, the strength test is divided into static pressure method, scratch method, rebound method, including microhardness, high temperature hardness and so on.
The test was carried out in an orderly manner, with exclamations from time to time.
Professor Chen, the yield strength result came out, 1600Mpa.
Only 1600Mpa?
Listening to Zhang Shitang's report, Chen Nuo frowned slightly, dissatisfied with the result.
Zhang Shitang almost choked to death listening to Chen Nuo's words, while the other three professors were stunned.
Only 1600?
They wanted to ask Chen Nuo if he knew what 1600Mpa represented?
The yield strength of ordinary steel is 300-500Mpa. The flight deck of an aircraft carrier is the strongest part of the entire aircraft carrier. It uses special steel, but it does not have such a high value.
In the aircraft carrier flight deck, M country uses special HY900 steel with a yield strength of 130, Fuso uses 1080Mpa special NS110, and Big Bear country uses 1300Mpa super alloy steel.
The yield strength of the alloy steel plate in front of me has far exceeded the yield strength of any country in the world that has disclosed alloys.
Converted to the data we are familiar with, a piece of alloy steel plate the size of a fingernail can withstand an impact of 16000 kilograms.
If this thing is used to make an aircraft carrier, the impact force of the plane taking off and landing will not cause the slightest damage to the deck.
Professor Chen, what is your estimated yield strength?
After the silence, Zhang Shitang asked in a low voice, and the other three also looked at Chen Nuo with burning eyes, and their hearts were tickled by Chen Nuo's words that there was only 1600.
I estimate it should be around 2200Mpa.
Chen Nuo replied casually.
hiss!
The four of them gasped in unison.
They really want to say that it turns out that we have not seen each other.
Professor, can it really be achieved?
When Zhang Shitang asked this question, he had no confidence at all.
Regardless of this, first test the rest, paying special attention to heat resistance, heat dissipation, magnetic properties, toughness, weldability, fatigue, plasticity, etc.
Ok!
The four of Zhang Shitang are as if they have been beaten to death, they are eager to know the remaining data of these characteristics.
Although they did not participate in the research on this alloy steel, but if they participated, there must be their names in the literature.
The reason why Chen Nuo focused on these data is because it is related to the scope of use.
For example, heat resistance is actually the melting point. The temperature of the combustion zone in the combustion chamber of an aero-engine is 1800-2000 deg;C. If this temperature cannot be reached, it will lose its meaning.
Another example is weldability, metals with good weldability, welded joints are not easy to produce cracks, pores and slag defects, and have high mechanical properties.
The flight deck is so big, it is impossible to produce a whole alloy deck, it can only be spliced piece by piece. If the welding is not good, it will definitely not be able to be used on the deck, and the engine of the fighter plane will be enough.
After half an hour, the weldability data comes out, good;
After an hour, according to the magnetic test, it was good:
Until more than ten o'clock in the evening, only the last test of heat resistance was the last of the dozen tests.
While everyone watched, the alloy steel plate was hoisted into a special blast furnace.
After turning on the power, the external temperature counter is changing.
300℃600℃1500℃1600℃
The four of them jumped up excitedly after seeing the alloy steel plate still kept black at 1600 degrees.
There are not no metals with high melting points. There are at least 18 kinds of elemental metals higher than 1600°C in nature. For example, the melting point of tungsten used in this blast furnace is as high as 3380°C, but its density is too high, three times that of ordinary steel.
If this thing is used as a fighter jet engine, the fighter jet may not be able to fly. It can only manufacture filaments, high-speed cutting alloy steel, superhard molds, etc.
The temperature in the blast furnace continued to rise.
180019002200 ℃
It didn't increase by 10 degrees, and the four of them thought it was a big test. They were all curious about the melting point, but they were afraid of being melted in the next second.
Chen Nuo was very funny watching the performance of the four people. According to his idea, he directly got it to 2800°C and tried it. If it didn't melt, it would be a success. If it melted, it would be a failure, because the information given by the system is 2800°C.
Ten minutes later, the temperature reached 2400°C, and the alloy just began to change slightly. At 2500°C, the alloy steel became red.
Stop quickly and get the alloy steel out.
Seeing this scene, Zhang Shitang yelled, and Gao Shizhong turned off the power at once.
Seeing this scene, Chen Nuo sighed softly, as expected, he did not meet the standard.
After the alloy steel was produced and placed in the blast furnace, the four were completely relieved.
Professor Chen, this alloy steel is too awesome!
Awesome!
Awesome!
Even though the professors have thousands of words, at this moment, they only have the word awesome to express their inner joy.
not bad!
There was also a smile on the corner of Chen Nuo's mouth.
Although it has not reached the final value given by the system, it is very good to reach this level in the first smelting, and it may be better to smelt it a few more times.
Zhang Shitang and other professors heard that Chen Nuo's performance was not bad, so they didn't react at all.
From the beginning of the test, every breakthrough test, Che Nuo is okay, only, so bad?Wait for such words, they are already numb.
You professors have worked hard, let's do this today, and tomorrow we will do some practical tests before doing it.
Professor Zhang, bring the material back to the material sample library of the Future Science and Technology Laboratory to seal it up, and start the first-level confidentiality procedure. No one is allowed to enter the sample library without my permission.
After Chen Nuo left, the four professors of Zhang Shitang began to get busy.
Hey, that's not right!
Zhang Shitang, who was busy working, suddenly let out a cry, which startled the other three people.
Lao Huang, when the heat resistance came out, I seemed to hear Professor Chen's sigh, can you recall it?
Hearing what Zhang Shitang said, the three of Gao Shizhong stopped their work, frowning and remembering.
No!
Zhang, you are not too tired during the day and have hallucinations!
The three responded in unison.
Zhang Shitang
Hearing the three people's responses, he was a little disappointed. When he reported to Chen Nuo, he was directly opposite Chen Nuo, and he definitely heard that sigh.
Why is Professor Chen sighing?Unsatisfied with the heat resistance data?Still not satisfied with the data from the whole experiment?
If so, where is the ultimate limit of this alloy steel talent?
Don't think about it, Lao Zhang, hurry up and work.
Chapter 414 Saturation Attack Test
Professor Chen?
Zhou Zhengfeng, who was reviewing materials, heard someone enter the office, looked up, and was surprised to see that it was Chen Nuo.
I heard that you smelted steel for a day at the Metal Research Institute of the Chinese Academy of Sciences yesterday. How was it?What gain?
