Live broadcast selling cement: Ask me if the launch silo can be used?

Du Yu asked the tester to continue to increase the strength of the machine, and the pointer of the toughness meter jumped to 2400J/M.

Wang Youde's heart was pounding and he shouted softly:

"It's going to break!

It's going to break!"

2400J/M should be the maximum measurement parameter of this German-made toughness measuring instrument, and it will no longer be measurable."

Luo Ming said proudly on the side,

"This thing is made of very good leather.

The maximum parameter measured by the newly imported Siemens Krupp machine in our testing room is 3000J/M.

After adding force, this pipe can completely withstand it without any signs of material fatigue!"

"So, everyone can see it clearly now,

I didn’t lie to you!"

All the experts present were silent, because everyone was basically sure that it was obtained from abroad.

Brigadier General Fan Jiang was eye-opening. He kept taking notes like a student, for fear of missing some details.

His intuition told him. His test today was of great significance.

Du Yu then asked the tester to drive the forklift to deliver the cement pipe to the high-temperature heating chamber to test the heat-resistant properties of the material.

The temperature of the high-temperature heating chamber was increased step by step,

1000 degrees Celsius!

2000 degrees Celsius!

Every other Ten minutes to increase the temperature by one level.

The experts present stood on their toes trying to see through the small glass observation window whether the tube had been burned and cracked.

The result was a bit disappointing.

The furnace wall was burned red and the tube was a little discolored. It turns white, but it doesn't turn red.

Du Yu asked the tester to continue to raise the temperature to

3000 degrees Celsius!

"Huo! I can’t accept it!"

The experts were all convinced and kept praising it.

4000 degrees Celsius!

5000 degrees Celsius!

The scene began to become commotion, and they all said that in the field of materials, we are working behind closed doors and are a little blindly optimistic.

"Foreign countries have imposed blockades and embargoes on our area for too long, which has led to everyone being self-righteous and thinking that the domestic level is at least catching up with the international advanced level, not to mention the international advanced level.

Lin Qisheng and Mr. Lin spoke at this time:

"We still have a long way to go, and we cannot be complacent or rest on our laurels in scientific research. Today’s test is very necessary and has sounded the alarm for our scientific researchers, especially materials researchers!

"

"If you fall behind, you will be beaten!

This sentence is not outdated today!"

The academicians and experts present were shocked and expressed that they were deeply educated today.

As the chief engineer of Blue Arrow Group, Sun Ke was shocked when he saw the test performance of this cement pipe so far. As a missile expert, the patience of materials Safety is an important indicator that he pays attention to, especially in the field of intercontinental hypersonic missiles he studies. At 7 to 8 times the speed of sound, the high-speed friction between the missile body and the atmosphere will cause the temperature of the missile shell to rise instantly, even reaching 3,000 to 3,000. 4000 degrees Celsius. If we need such good heat-resistant materials and heat-resistant materials, the performance of missiles can be greatly improved. If we can develop such advanced cement, we can completely turn it into coatings for missile casings.

"Why! It's a pity that this material is not ours!"

Chief Sun sighed,

"I have been engaged in missile research for decades, and I have become more and more aware of the importance of materials research.

If one material is not up to standard, we will be stuck.

The international community begs grandpa and grandma to search everywhere to modify or imitate civilian materials. That's a common thing.

If the materials are not up to par, no matter how excellent the design is, it will not come out.

At the same time as the new heat resistance test, the heat resistance results of the sample also came out, and the heat resistance was 50%.

Sun Ke just took a look at it and concluded that the heat resistance of this thing is not bad, because the temperature is heated to four to five thousand degrees Celsius, and his The color change is not very noticeable.

However, the 50% thermal resistance still surprised the academicians and experts present.

Mr. Lin said tremblingly:

"I have been engaged in rocket and missile research all my life.

If the heat resistance and heat resistance of a material reach such an incredible level, its prospects in aerospace and ballistic missiles will be very broad.

Rockets have such isolation There is no need to worry about cracks and safety issues in the thermal layer, and there is no need to worry about deformation of engine parts.

Even some high-temperature parts can be directly cast using this material.

The principle is the same for hypersonic missiles.

The speed can be increased, and the suddenness and timeliness of the attack will be greatly improved.

The opponent's anti-missile system will simply not be able to track such a high-speed target. It only takes 20 to 30 minutes for us to reach any corner of the Eastern or Western Hemisphere. In the field of manned spaceflight, our rockets can be designed to be larger and carry larger loads. For landing on Mars, if we can carry hundreds of tons of cargo at a time Once launched, the cost of building a Mars base will be greatly reduced. The field of fighter bombers also has broad application prospects. Both can fully achieve hypersonic cruise. Current air defense missiles or anti-air missiles may not be able to catch up with the speed of aircraft. There are also

……

This material has such a wide range of applications that it can do anything! Mr.

Lin sighed,

"If only we could have it.

If I were 20 years younger,

I would definitely reverse engineer it.

Its importance is definitely no less than that of atomic bombs, hydrogen bombs and neutron bombs!"

"Time waits for me! When talking about the emotional point,

Lin Laolian covered his face and wiped the tears from his eyes.

Everyone tried to persuade him:

"Mr. Lin, take care of yourself!"

"Just leave these to our young people!"

"Please don't be overly sad, the country cannot live without heroes like you!"

Du Yu ordered the tester to test the last item, cold resistance.

After the pipe was cooled, it was sent to the freezer.

The temperature gradually dropped from minus 50 degrees Celsius to minus 100 degrees Celsius.

There was no abnormality in the cement pipe.

Then it dropped to 150 degrees Celsius, and finally dropped to 150 degrees Celsius. It reached 200 degrees Celsius.

Du Yu ordered the tester to use a large pressure machine to squeeze the pipe.

As a result, the pressure of the pressure machine was increased to 4000.

The pipe did not crack,

5000 still did not crack,

6000 did not crack, and

7000 still did not crack.

Already When the maximum value was reached,

Chen Qimei and Ma Lin took a deep breath.

"Huo! Steel will become brittle at minus 50 or 60 degrees Celsius, and it will easily break under added force.

This sample is really a treasure. It is extremely tough at minus 200 degrees Celsius."

It means that our launch silo can be deployed to any cold zone.

Mr. Lin became more and more excited and introduced excitedly:

"In the field of space exploration, spacecraft must not only be heat-resistant, but also cold-resistant, because in corners of the solar system or even the Milky Way where sunlight cannot be found, the temperature is extremely low and existing spacecraft cannot reach it at all.

Even if the original parts are basically invalid,

Totally unable to work.

If there is such a material, the field of space exploration will be greatly improved.

Heat can go to Venus and Mercury, cold can reach Pluto, etc., and places where there may be signs of life such as Callisto and Titan can also be detected for a long time without being affected by it. Influence!"

"This can completely benefit the entire human race,‘

"I dare to conclude that in the next 5 to 10 years, the entire human spaceflight industry will enter a new era and will usher in an epoch-making revolution, all thanks to this material!"
