Chapter 81 What kind of magical unit
Old Chen showed Deputy Section Chief Zhao and Gao Zhendong the reporting requirements written down on the phone: "Comrade Zhao Hong, please organize people to fill in the reporting requirements within tomorrow." Send it to the ministry. Zhendong, please cooperate."
Gao Zhendong asked: "Okay, whether it is mass production or not?"
Old Chen thought for a while: "As long as there is. Report them all."
Gao Zhendong nodded: "Okay, then when I was making 3Z-591, I would also report some of the things I messed up. Although they are not mass-produced, I have mastered the production process and material properties.”
Lao Chen laughed: "Please report it, please report it. It will also make our factory's products richer, haha."
These words played into Gao Zhendong's heart. Back in the office, Gao Zhendong also put in the special materials he had tinkered with. List of reported products.
By this time, Gao Zhendong, relying on his powerful memory, had already created two kinds of special materials.
After reporting the list from the Technical Section to Deputy Section Chief Zhao, Gao Zhendong took out the prepared special material samples and test records from the storage warehouse, marked 3Z-T1, 3Z-T2, and placed After entering the sample library in his team's office, he greeted Liang Fafa and the others and explained the general situation.
The next day was Friday, and Gao Zhendong took a day off. He needed a good rest. Writing a mathematical toolkit was really energy-consuming.
There is a saying that goes well, your eyes can deceive you, your ears can deceive you, but you can’t do math. If you can’t do math, you really can’t do it.
The implementation of each mathematical tool is based on the premise that Gao Zhendong himself first learned the tool and then found a way to implement it on a computer with a word length of only 8 bits.
But fortunately, Gao Zhendong is not planning to take over the world by himself. He just wants to implement some basic tools that can demonstrate the capabilities of this machine, and others will complete the rest.
Gao Zhendong’s request for leave went smoothly. The reason is self-evident. Ability is the last word.
When Gao Zhendong was relaxing and playing with his children in the yard, their product list had already been reported to Machinery Department No. 17.
Comrades at the Prairie Tractor Factory are sifting through the list of products that have been submitted one after another. The situation is not optimistic. The products are highly duplicated and there is nothing worthy of attention. It is far from enough to replace nickel-containing armor steel.
The military comrades who were with them were also helping with the screening. Although they were not as familiar with the detailed indicators as the comrades at the tractor factory, the hardness indicator was still no problem for coarse screening.
After all, armor steel, let’s talk about whether it is hard or not. If the hardness is not enough, other mechanical indicators will not be discussed.
Time flowed away amidst the boring sound of turning pages. Except for the sound of turning pages and occasional whispered exchanges, the scene was quiet.
Suddenly, a military comrade shouted "Ah": "Ah, did they make a mistake in reporting this material? The hardness of this alloy steel is so high?"
The other comrades all became energetic, put down what they were doing, and started asking him questions.
“What did you find?”
“How hard is it?”
“Let me see, let me see.”
This comrade held Material, read it again: "Bricknell hardness, HBW10/3000, greater than or equal to 370, less than 480."
This time the whole scene was blown up. What is the concept of Brinell hardness between 370 and 480? For example, the 5DL tank is copied from the 74n and 75n high-nickel armor steel used in the original T-54/55 in the north. The Brinell hardness is about 300. The domestic 601 nickel-free armor steel was developed in the 1960s to replace it. The hardness is about 290.
"How much? How much?"
"Give it to me, let me see it, let me see it."
"Is it impossible? Is it an error?"< br>
“Look at other mechanical properties, look at other mechanical properties.”
"Look at the mechanical properties! It's called steel, and the other mechanical properties won't be too bad. Look at the material ratio! Look at the material ratio!" The scene suddenly became a mess, but most of them were excited.
At this time, the technical leader of the Prairie Tractor Factory, Mr. Guan, stretched out his hand: "Give it to me, let me see!!!"
Get the materials , he couldn’t wait to look at it carefully.
“The hardness of 3Z-T1 alloy steel is indeed so high, and its mechanical properties fully meet our requirements, and even exceed them.”
"Rolled materials can be used for steel plates of various thicknesses. The turret is no longer needed, but the car body half can be solved, great!!"
The 5DL's turret is a cast turret, cast. The requirements for steel and welded steel are different.
"The material ratio, well, the specific ratio is not written, only the ingredients are written. Iron, carbon, silicon, manganese, phosphorus, sulfur, boron, titanium are gone? Is that gone? No nickel , no chromium, no molybdenum? ! ”
These things are strictly controlled abroad, and the domestic production is not high at this stage.
Hearing this, everyone couldn't believe it: "What? You don't need nickel, chromium, or molybdenum? This is not true."
The following words were not spoken, but the meaning was self-evident.
Mr. Guan looked at the unit where the materials were submitted, the Third Steel Rolling Mill in Beijing. This gave him some confidence. The big factories in the Forty-Nine City are less likely to have trouble. Look. I looked at it and saw that the material was not finished yet, so I turned back a bit.
When I turned it over, my eyes became straight again.
"What? There is another kind? 3Z-T2 cast steel?"
When everyone heard this, they were numb. What kind of magical unit is this? There is a rolling plate, but also a casting?
"Mr. Guan, look, look, what does this cast steel mean?"
"The mechanical properties are no problem with a hardness of 300hb, carbon, silicon, manganese, and nickel."
Everyone listens , lost interest.
“It contains nickel, so it’s useless.”
“It’s a pity.”
Mr. Guan added: "However, the material indicates low nickel, which may be a way. I just don't know if this material is true."
Seeing this, the soldiers together couldn't sit still. He said: "The Third Steel Rolling Plant in Beijing is located in this city. You will know if you really look at it." Leaders of the Machinery Department, please coordinate with them and we will go take a look right away." After that, he turned around and told everyone to continue working, and went out with Staff Lin.
In the leadership office, Secretary Zheng sat down with two people. The two took out the submission materials from the third rolling mill and explained the situation. At the same time, they also revealed their worries.
The leader took a look at the materials and smiled: "The third steel rolling mill? Haha, if it is another factory, I can't say, but if it is submitted by the third steel rolling mill, then I am really sure."
Mr. Guan and Staff Officer Lin looked at each other, overflowing with joy. The leaders of the 17th Machinery Department said this, and it should be well-founded.
Mr. Guan smiled and said: "That's great. It seems that the third steel rolling mill in Beijing is very powerful."
