Chapter 275 Book two first prizes
The comrades in the Publicity Department finished their work quickly and went back to write the manuscript.
General Manager Chen used the fastest speed to revise and sign Yu Yuncheng’s report, and then mobilized many comrades from the confidential office and publicity office to copy the details of the monocrystalline furnace and monocrystalline silicon. Report.
How many pages do you have and how many pages do I have? It’s done very quickly. But some people have to worry about what if the handwriting is different?
Many of the comrades engaged in propaganda these days have a unique skill called printing.
It means writing according to the printed font. As long as they are all masters, the words written by different people will not look exactly the same, at least they will be close to each other.
So in the afternoon, the three monocrystalline silicon rods were sent to the National Academy of Sciences and two ministries together with the report, escorted by the factory militia.
In addition to single crystal silicon rods, the 17th Machinery Department also received reports on tungsten-molybdenum alloys.
At first glance, the leader’s eyes were straightened. The melting point is 2600°C? At the same time, it has good processing performance and can be forged, rolled and turned?
There are many metals with high melting points. Among other things, the melting point of tungsten itself, one of the components of tungsten-molybdenum alloy, has reached over 3400°C. However, the processing performance of this thing is not very good. , forging, turning, no matter which one, there are not many people who can chew this thing.
It is difficult to process, which greatly limits the application of tungsten's high-temperature properties. However, this thing made by Gao Zhendong can easily perform these processes. This is different. It can be used in many places.
It would be great if the density could be close to that of steel, no, copper, then it could be used in more places.
Thinking of this, the leader couldn't help but scold himself, what good thing could he think of? You want everything, right? Ha ha.
Of course, good processing performance often means another problem: it is not so hard, but that doesn’t matter. What is important here is high-temperature performance, not hardness.
This is also one of the reasons why tungsten-molybdenum alloy is not used in armor. In addition to being too heavy, its specific gravity is about 18, which is really incomparable with steel alloys of about 7.8. At the same time, its hardness is compared to High-hardness armor steel has no advantages.
The hardness of tungsten-molybdenum alloy is about 60-70HRC. Taking the 592 nickel-free alloy armor steel made by Gao Zhendong as an example, the hardness is 370~480HB. A conversion needs to be done between HRC and HB.
HRC=0.098×HB+32.25.
If you do the math, you will know that the hardness of tungsten-molybdenum alloy is even lower than 592 armor steel.
But this does not affect the use of tungsten-molybdenum alloys. We not only want a torrent of steel, but we also want a major industrial wave, aerospace.
After reading the report on tungsten-molybdenum alloy from beginning to end, the leaders were very excited. This is different from materials such as 592 and 593, which have special uses and are basically limited to the military industry. They can be used in any industry. , something that can be used as long as the needs match.
He immediately called the people from the confidentiality department and handed them the tungsten-molybdenum alloy material: "Desensitize this material and then immediately report it to the Ministry of Machinery, the Ministry of Science and Industry and relevant ministries."
The comrade from the confidentiality department immediately took action, and then he read another report with a comfortable mood.
Single crystal furnace and silicon single crystal.
As soon as he read the beginning, he stood up, rushed to the door in a few steps, and asked Secretary Sun: "Xiao Sun, does this report come with a sample?"
< br>Secretary Sun said: "Yes, there is a sample."
"Take me to see it right away. By the way, go and call the chief engineer of the department immediately!"
At this time, he no longer cares about "calling" and "please", and he wants to aggrieve the chief engineer. Bar.
Hurrying to the warehouse where the silicon monocrystal rods are placed, the leader looked at the silicon monocrystal in front of him and was dazzled. This is the hometown of the 17th Machinery Department. For him, it is better than DJS-59. and lasers fascinated him even more.
Haha, Gao Zhendong has been doing research for so long, and he has finally got a treasure for the 17th Machinery Department. Although the 59X series is also groundbreaking, they are all pioneering in specific materials and generally do not jump out of the "iron-based alloy" framework.
As for silicon monocrystalline, it can be said that it pioneered the silicon industry. So far, everyone engaged in silicon-related industries cannot avoid it. Especially the 12th Machinery Department, hehe, thinking of this, the leader of the 17th Machinery Department laughed out loud.
After a while, the chief engineer of the 17th Machinery Department also arrived here. Hearing what the leader said, he was overjoyed. As the technical leader of the 17th Machinery Department, he knew what this thing represented better than the leader.
He "snatched" the silicon monocrystal report from the leader rudely, took off his glasses, tilted his head, put the report a certain distance away from his eyes, and squinted carefully. Looked up.
Reading glasses are like this. If they are too close, they won’t work. Many old people see things this way.
The chief engineer looked gradually excited.
This means that the source of semiconductor materials that has been troubled before has been completely solved. Let alone silicon, the earliest germanium tubes used germanium extracted from furnace ash, and silicon tubes except In addition to being inferior to germanium tubes under special requirements, the characteristics of silicon tubes are comprehensively superior. The biggest obstacle limiting the application of silicon tubes is the raw materials.
He knew that the 1761 Institute had pulled out silicon single crystal with four nines last year, but it was still an order of magnitude short of being used in the electronics industry. And as far as he knew, the four nines route was successful, but the technology was still there. Far from reaching maturity.
Because of this matter, he was often laughed at by the chief engineer of the 12th Machinery Department. The most common sentence he said was: "We can design this thing, but the 17th Machinery Department has no materials for it. We can’t make it either.”
Now that the third rolling mill has produced a silicon single crystal that is better than five nines, I wonder what other excuses he can make, hahaha, I want to squat on him every day. At the door, see what he can create. Even if it was pulled out by accident, it doesn't matter. If it can be pulled out, it means that the technical route is correct and can work. At the most, research and improvement can be done to increase the yield rate.
Everyone who is engaged in technology knows that there is a huge difference between "0" and "1".
If the four nines do not require in-depth research and improvement and optimization of the process, then the five nines of single crystals are very necessary.
After looking at all the parameters of the silicon monocrystal one by one, the chief engineer smiled and said: "Boss, it's only April, and the third rolling mill has already reserved a place for the first prize of this year's Agni Technology Award. "
The leader smiled and pointed at the materials in his hand: "Don't get excited. Looking back, there may be more than one."
The chief engineer looked puzzled. ?
He continued to turn back and suddenly looked ecstatic.
What did I see? "Universal single crystal furnace"?
The chief engineer of the department suppressed the joy of swearing. It was not a typo or the wrong word, but the combination of these two seemingly incompatible words really represented his current mood. .
Single crystal furnace, as soon as you look at the name, you will know that this is a standard mass-produced equipment for the mass production of silicon single crystals.
It is a mouthful to read, but this is a portrayal of the facts.
It can be used for mass production of silicon single crystals, and the equipment itself is mature and has the conditions for mass production.
The mood of the chief engineer is now like a tide, one wave after another. There are 59 silicon monocrystals~~~~~~Silicon monocrystal energy has been produced~~~~~~Silicon monocrystals have been mass-produced. The crystal equipment has also reached capacity~~~~~~
He was just thinking that if this silicon single crystal was an accidental or experimental result, then he must support the third rolling mill to develop it. Go down and be mature.
Now I find that no need, others have solved it, and they have solved it very thoroughly.
He turned his head and said to the leader of the 17th Machinery Department: "Leader, you are right, here are two first prizes of Agni Technology. They are not running away."
Leader haha Laughing: "You are wrong. We have to look at the problem from a development perspective. Maybe by the end of the year, we will only be able to win the second prize."
The chief engineer didn't pay attention to the leader's joke at all: "I don't believe it! This is the first prize. It has to talk about development and objectivity. We will notify the 12th Machinery Department immediately. I wonder what the chief engineer will look like when he sees this. , Haha, this time he has no excuse!"
The leader smiled and shook his head: "No need to notify, the third rolling mill has already notified them, and also sent them a silicon single crystal. For testing, not only the 12th Ministry of Machinery, but also the National Academy of Sciences. "
The chief engineer was stunned: "They are thoughtful. The National Academy of Sciences does the final appraisal, and the 12th Ministry of Machinery does the application appraisal. Doing project appraisal, haha."
Then he suddenly reacted: "They sent three at a time? This means they are fully capable of mass production, good thing, great thing, hahaha."
< br>The leader smiled and said: "Not only that, they have even tried things other than silicon single crystals. They have pulled aluminum oxide crystals with the same success. This shows that they are confident in saying that this furnace is a 'universal single crystal furnace' .”
The chief engineer smiled at the leader and said: "It seems that the ministry has decided to fully support Comrade Gao Zhendong of the No. 3 Rolling Plant without setting any restrictions on him. This is a right move. You have promoted this matter with all your strength. Gao Zhendong has not I failed to live up to your expectations.”
Hearing this, the leader laughed proudly. He was willing to wear this high hat, and it was very comfortable to wear.
The Seventeenth Machinery Department is excited, and the Twelfth Machinery Department is also in a state of excitement.
When the leader of the 12th Machinery Department received the news, he looked astonished at the secretary who came to report: "What did you say? The No. 3 Rolling Mill of the 17th Machinery Department sent a silicon single Jing? "
As a subordinate unit of other ministries and commissions, and things that are very important at first sight must be reported to him.
These days, nothing about materials is unimportant.
What's more, the Third Steel Rolling Plant, Gao Zhendong, needless to say, report to the top leader.
So the news reached him as soon as possible.
He remembered that at the beginning of the new year, Gao Zhendong said this at a meeting. He was leading Comrade Yu Yuncheng from the 1761 Institute to pull silicon single crystals that met the needs of the electronics industry.
But he didn’t expect that things would already be out in just a few months.
He is the leader of the 12th Machinery Department, and he knows very well the uses of silicon single crystal and the difficulty of high-purity silicon single crystal.
