Chapter 81 What kind of magical unit

Old Chen showed the report requirements he wrote down on the phone to Deputy Section Chief Zhao and Gao Zhendong: "Comrade Zhao Hong, please organize some people to fill out this report and try to get it to the department tomorrow. Zhendong, please cooperate."

Gao Zhendong asked: "Okay, we'll report it regardless of whether it's mass-produced or not?"

Lao Chen thought for a moment and said, "Just report whatever is available."

Gao Zhendong nodded: "Okay, then I'll report on the few types I tinkered with while making 3Z-591. Although they are not mass-produced, I have mastered the production process and material properties."

Lao Chen smiled and said, "Go ahead and report it. It also makes our factory's products look richer, haha."

Gao Zhendong was pleased with what he said. After returning to the office, he included the special materials he had tinkered with into the list of products to be reported.

By this time, Gao Zhendong had already created two kinds of special materials with his powerful memory.

After reporting the list from the Technical Department to Deputy Section Chief Zhao, Gao Zhendong took out the prepared special material samples and test records from the storage, marked them 3Z-T1, 3Z-T2, and put them into the sample library in his group office. He then greeted Liang Faming 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 the math toolkit was really very energy-consuming.

There is a joke that goes, your eyes can deceive you, your ears can deceive you, but not math. If you don’t know math, then you really don’t know it.

The implementation of each mathematical tool was based on the premise that Gao Zhendong first learned the tool and then found a way to implement it on a computer with a word length of only 8 bits.

Fortunately, Gao Zhendong is not planning to do everything by himself. He just wants to implement some basic tools to demonstrate the capabilities of this machine, and the rest will be improved by others.

Gao Zhendong's leave application went smoothly. The reason was self-evident: ability is the bottom line.

When Gao Zhendong was relaxing and playing with his children in the yard, their product list had already been reported to the 17th Ministry of Machine Building.

Comrades at the Grassland Tractor Factory are screening the list of products that have been submitted to them. The situation is not optimistic. There is a large degree of duplication among the products and there is nothing eye-catching. It is far from enough to replace nickel-containing armor steel.

The military comrades with them were also helping with the screening. Although they were not as familiar with the detailed indicators as the comrades from the tractor factory, there was no problem using the hardness indicator for rough screening.

After all, it is armor steel. Let’s first talk about whether it is hard or not. If the hardness is not enough, other mechanical indicators are out of the question.

Time passed with the boring "rustling" sound of turning pages. Apart from the sound of turning pages and occasional whispered conversations, the scene was silent.

Suddenly, a soldier cried out, "Ah, did they report the wrong material? The hardness of this alloy steel is so high?"

All the other comrades became excited, put down what they were doing and asked him questions one after another.

"What did you find?"

"How hard?"

"Let me see, let me see."

The comrade took the material and read it out: "Brinell hardness, HBW 10/3000, greater than or equal to 370, less than 480."

This made everyone at the scene explode. What does a Brinell hardness of 370~480 mean? For example, the original T-5/54 tanks used in the copy of the 55DL tanks use 74n and 75n high-nickel armor steels, with a Brinell hardness of about 300. The 1960 nickel-free armor steel developed in China in the 601s as a substitute has a Brinell hardness of about 290.

"How much? How much?"

"Give it to me, give it to me, let me see it."

"Impossible? Was it a mistake?"

"Look at other mechanical properties, look at other mechanical properties."

"What's the point of looking at mechanical properties! It's called steel, so its other mechanical properties shouldn't be too bad. Look at the material ratio! Look at the material ratio!" The scene was suddenly a mess, but most people were excited.

At this time, General Guan, the technical leader of the Grassland Tractor Factory, stretched out his hand and said, "Give it to me, let me see!!!"

After getting the materials, he couldn't wait to read them carefully.

"3Z-T1 alloy steel, the hardness is indeed as high as it is written, and the mechanical properties fully meet our requirements, and even exceed them."

"Rolled material, can be used for steel plates of various thicknesses. The turret is no longer needed, but the hull half can be solved, great!!"

The turret of 5DL is a cast turret, and the requirements for cast steel and welded steel are different.

"The material ratio, um, there is no specific ratio, only the ingredients. Iron, carbon, silicon, manganese, phosphorus, sulfur, boron, titanium are gone? That's it? No nickel, no chromium, no molybdenum??!!!"

All of these things are strictly controlled by foreign countries, and at the same time, the domestic production is not high at this stage.

After hearing this, everyone couldn't believe it: "What? Nickel, chromium, and molybdenum are not needed? This is so ridiculous."

The following words were not spoken, but the meaning is self-evident.

Mr. Guan took a look at the unit that submitted the materials, the Third Steel Rolling Mill in Beijing. This gave him some confidence. It was less likely that there would be any problems with such a large factory in the city. He took a look and found that the materials were not finished yet, so he flipped to the back.

After turning over, his eyes became straight again.

"What? There's another kind? 3Z-T2 cast steel?"

When everyone heard this, they were stunned. What kind of magical unit is this? They have plate rolling and also casting?

"Boss Guan, take a look, take a look, what does this cast steel mean?"

"Hardness 300hb, mechanical properties are fine, carbon, silicon, manganese, nickel."

After hearing this, everyone lost interest.

"It contains nickel, so it's useless."

"What a pity."

Mr. Guan added: "But the material specifies low nickel, so maybe that's a solution. I just don't know if the material is genuine."

Seeing this, the soldiers couldn't sit still anymore: "The Third Steel Rolling Mill in Beijing is right in this city. You'll know if you really want to see it."

Guan Zong thought about it and said, "Staff Officer Lin, let's go find the leaders of the 17th Ministry of Machinery and ask them to coordinate. We will go and take a look right away."

After saying that, he turned around and told everyone to continue working, then went out with Staff Officer Lin.

In the leader's office, Secretary Zheng sat down with the two men. They took out the report materials submitted by the Third Rolling Mill and explained the situation, while also indirectly revealing their concerns.

The leader took the materials and looked at them, then laughed: "The Third Steel Rolling Mill? Haha, if it was any other mill, I can't say for sure, but if it was reported by the Third Steel Rolling Mill, then we have a pretty good chance of success."

General Guan and Staff Officer Lin looked at each other, their joy evident in words. Since the leaders of the 17th Ministry of Machine Building all said so, there must be a reason for it.

Mr. Guan smiled and said, "That's great. It seems that the Third Steel Rolling Mill in Beijing is very powerful."
