The 80,000-ton super-large die forging machine, like a steel monster, sits quietly in the tall workshop.

The height above ground is 27 meters, 15 meters deep underground, and the total height is 42 meters.

It is equivalent to a 13-storey building.

The weight alone is 28,000 tons!

It is the strongest steel machine of mankind deservedly.

The forging table is capable of providing a strong pressure of up to 1000MN.

Equivalent to a whole nuclear-powered aircraft carrier, pressed on its forging platform.

In order to build this world-class industrial manufacturing equipment, domestic industrialists have spent nearly 30 years.

Since more than 20 years ago, we have been exploring the manufacturing technology of 80,000 tons of large-scale die forging machines.

Over the years, we have continuously overcome difficulties in hydraulics, electromechanical, transmission and so on.

Finally completed this steel behemoth that can be called the blood-making machine of the Republic.

With it, it is possible to continuously manufacture very large steel components.

The processing problems that have plagued us for a long time have all been swept away.

For example, the Yunshi project, which unfortunately died 30 years ago.

To a large extent, it was due to the fact that there was no large-scale die forging machine that could process large fuselage girders in China at that time.

After the successful test flight of the Yun-10, it only flew for 170 hours before it had to stay on the ground permanently.

That's why, now, it's possible to create a super-large long-range stealth bomber.

As well as a large strategic transport aircraft that is nearing completion.

"The big forging machine can only be used by you once, so you must cherish it."

Chen Xiaoci glanced at his watch and looked serious.

As the most forging capacity of the die forging machine in China.

I don't know how many people are staring at this machine.

If you really ask someone from the Railway Research Institute to make an appointment, it is estimated that the queue will be able to wait until three years later.

In the end, it was Zhang Xingyang who found a way to get a chance to cut the queue.

"Understand, I'm sorry for you this time!" Geng Bo's face glowed red, and he looked at the forging table that revealed a fiery red color.

What they cut into the queue and squeezed out was the forging and forming of the fuselage girders of domestic large transport aircraft.

They had to wait another three days for this.

The person in charge of the forging and forming project of the fuselage girder of the large transport aircraft is Chen Xiaoci.

"Hopefully you'll be able to really succeed this time."

Chen Xiaoci put his hands in his pockets and looked at the rumbling machine.

It seems to be Liuding Liujia, the imperial envoy Shenhuo True Thunder, tempering a peerless divine weapon.

In a sense, the keel made of titanium-nickel alloy is also a super weapon.

Inside the forging machine, the metal ingots are ravaged as if they were dough.

Under the strong pressure of the hydraulic system, the titanium-nickel alloy, which ranks among the top in strength on the earth, is nothing more than a mass of plasticine that can be easily rounded and flattened.

"It will be successful, we have enough confidence in the die forging machine."

Geng Bo pushed his glasses and said.

Strictly speaking, the requirements of titanium alloy dragon kingdom actually exceed the fuselage beam forging requirements of large transport aircraft.

The reddish metal ingots emit a scorching smell on the forging table.

The metal ingot, which was originally a cuboid shape, became smaller and smaller under strong pressure.

In this process, the grains of the metal will be gradually refined, so that all aspects of its performance can be improved.

An hour later, "Boom! Rumble! Rumble! The sound stopped.

A bunch of people gathered around the forging table of the 80,000-ton die forging machine, ignoring the flying sparks above and the rising temperature.

The previously closed forging table slowly opens.

The titanium-nickel alloy keel, weighing more than 100 tons, was forged.

Hundreds of meters long titanium alloy, shimmering golden red.

People can't help but think of the legendary Dinghai God Zhen Iron - Ruyi Golden Hoop Stick.

It is rumored that it is used by Dayu to control the water, weighing 13,500 catties.

But compared with this super stick that is 450 meters long and weighs 200,000 catties.

It's nothing.

The thick robotic arm puts the titanium alloy keel that has not yet cooled and puts it in a circle made of two iron cables.

Then the large gantry crane in the factory slowly moved it to the side.

In case the ground was melted down, it was not put down.

Instead, it is suspended directly in the air for cooling.

"Will there be any minor trimming after that?"

Geng Bo's eyes kept staring at the titanium alloy keel, and he asked Lao Huang without looking back.

Lao Huang is not the first time to use this 80,000-ton die forging machine, and he has some experience.

"In our previous experience, it wasn't needed."

"Although the metal that is generally smelted will inevitably have microscopic cavities inside."

Lao Huang said eloquently: "But the strong pressure of the die forging machine can save us from this trouble, and it will fill all the defects inside." ”

It is difficult to avoid microscopic cavities inside large metal blocks.

These are basically caused by the entry of air and the like into it during the smelting process.

Although it is not like castings, large cavities that are visible to the naked eye will occur.

However, subtle voids will still have a greater impact on the strength of structural parts.

If the metal ingots that have just finished smelting, they are a large mass of dirt that does not solidify.

Then the alloy keel that has been ruthlessly ravaged by the 80,000-ton die forging machine is the steel knife that has been polished.

Almost indestructible!

"Let's go over there and have a look."

I saw the extra-long titanium alloy keel slowly cooling.

It has returned from a golden yellow color at a high temperature to a silvery white color at a low temperature.

It's no longer so dazzling, but it makes people feel hard.

"I don't know if it can support the massive space station structure."

Geng Bo carefully looked at the titanium alloy keel in front of him, which was not thick, and thought to himself.

The titanium keel is no more than fifteen centimeters thick.

It feels like it's tilted and it might even break on its own.

But it has extremely strong stiffness.

The two suspension points, which are separated by hundreds of meters, still do not show elastic deformation in the center that can be distinguished by the naked eye.

Drum type space port, they are also preliminarily designing some simple cabins.

These cabins are planned to be composed of arcs.

Each section of the arc is more than 300 meters long, and the mass is at the level of 1,000 tons.

The overall quality has reached tens of thousands of tons.

The tens of thousands of tons of starport cabins are hung on such alloy sticks that are less than 20 centimeters thick.

"Get ready to do all aspects of performance testing."

Geng Bo commanded to the people around him.

With a 450-meter-long alloy keel, it is not an easy task to do it once.

The process of transferring the alloy keel alone took several hours.

In the end, a test bench was built for it.

Because of the traditional test bench, it is difficult to put down.

It is possible that the test bench of the Railway Research Institute, which is specially used to test seamless rails, can be placed.

It's not very convenient, though.

Forging a titanium keel, it took an hour.

The preparation time for the test alone took nearly three days.

Another five days passed for the subsequent tests.

It took more than half a month before and after, and Geng Bo finally got the first titanium keel.

And the relevant test work has been completed.

"It should barely meet your application standards."

Lao Huang said after taking people to complete all the test items.

"In terms of strength, it is just up to standard, and in terms of stiffness, it is still a little exceeded."

In fact, if he was able to reach 90 percent of the predetermined goal, Geng Bo was already satisfied.

It's a surprise to be able to meet all of them now.

"When we finish the high-temperature memory test, we can officially start production."

Lao Huang's eyes seemed to be able to jump out of the symbols of small money, and he was extremely excited.

When production officially starts, they will be able to eat this huge amount of orders.

"Our high-temperature memory test is very demanding."

Geng Bo reminded.

"If we can't get through, then we can't place an order."

Lao Huang could understand the other party's caution and didn't say anything.

Directly with people, the high-temperature memory test began.

Before that, it needs to be processed at high temperatures.

The first is to heat the temperature to close to 100 degrees in the machining chamber where the alloy keel is located.

This temperature is not considered high temperature for titanium-nickel alloys.

Its other performance has hardly changed significantly.

A special bending machine that bends the alloy keel slowly.

The ultra-high stiffness of titanium-nickel alloy has become a difficult mountain to cross at this time.

The special powerful bending machine has been driven almost to the maximum power.

However, the alloy keel can only be broken little by little.

The keel even made a tooth-aching creak.

The bending machine worked at full capacity, and it still took ten hours.

Only then will the alloy keel be coiled into a circle-by-circle shape.

It became an oblate disc with a diameter of about 10 meters.

A little over three laps in total.

However, it is also due to the ultra-high stiffness, after bending, the rebound speed of the alloy keel is very slow.

If it stays at about 100 degrees, it will not even rebound.

"Now reduce the ambient temperature to room temperature."

Under Lao Huang's order, several powerful fans in the processing room turned on, blowing away the original heat in the processing room little by little.

In the process, the originally hovering alloy keel also began to slowly straighten at a speed visible to the naked eye.

The cooling speed of high-power fans is even faster than that of high-power air conditioners.

In less than 30 minutes, the processing room went from a high temperature of 100 degrees to close to room temperature.

The flat disc-like alloy keel, the outermost circle has also been opened.

It turned into an irregular circle.

"It looks like it's going to be completely restored within an hour."

Lao Huang also had a little confidence at this time, and said to Geng Bo with a smile.

Geng Bo didn't say anything, but stared closely at the alloy keel that was still slowly stretching in the processing room.

Lao Huang also turned his head, looked at the alloy keel, and kept muttering in his heart.

Hopefully, this titanium steel rod will be able to restore the prototype soon.

It's better not to bend at all.

Among the requirements, the straightness of the titanium alloy keel after restoration is very high.

Maybe Lao Huang's prayers played a little role.

An hour passed in the blink of an eye.

The titanium keel has been restored to its straightness on the surface.

With the naked eye, there is not a little bending.

But what is the specifics depends on the data measured by the straight measuring instrument.

"The overall flatness error is 4mm, which is 20% better than our requirements."

After measuring the data, Lao Huang's hanging heart finally let go.

This means that this order, which is worth hundreds of millions of dollars, has basically gone into their pockets.

Geng Bo stroked the titanium alloy keel that had cooled down and exuded an icy aura, as if he had seen it standing in the universe.

"The flaw detection has been done."

Lao Huang then said, "There is no damage found inside. ”

"The deformation didn't have much consequence."

"Of course, this may also be due to the fact that only one transformation was performed."

"If you deform a few more times, there may be some damage inside."

"Do we need to do another high-temperature memory test?"

Geng Bo waved his right hand, "No need, it's enough to have a single two-way memory effect." ”

Although I don't know what the other party is trying to use this very strange thing for.

But Lao Huang was still very witty and didn't ask too much.

Sometimes knowing too much is not a good thing.

Although he also has curiosity, his curiosity is focused on the technology itself.

I don't really care where it's going to be used.

No matter what the other party says, he is also a member of the national scientific research system.

Anyway, it can't be used in a bad place.

"Then shall we go straight to the rest of the manufacturing work?"

Lao Huang kept rubbing his hands excitedly.

"We still have 11 manufacturing tasks in the future, so let's prepare to start construction officially."

Geng Bo removed his hand from the silver-white titanium alloy keel, shook hands with Lao Huang and said.

In fact, the entire starport only needs about ten titanium alloy keels.

The extra two are available as backup parts.

Prevent keel damage due to various accidents.

After all, when the rocket launches work, it is difficult to guarantee that nothing goes wrong and there will never be accidents.

And in the event of an accident, it is basically determined that the keel on it is damaged.

In fact, major aerospace engineering projects will have backups.

Satellite projects will have backup satellites, backup rockets.

The manned spaceflight program is a manned spacecraft that will have a backup.

Therefore, the titanium alloy keel launch project should also have a backup titanium alloy keel.

"Then our contract, will we be able to complete the signing work today?" Lao Huang smiled so much that folds were piled up on his face.

Geng Bo also laughed and said, "Of course, we can complete the signing of the contract now." ”

The contract was signed in duplicate and was quickly signed.

Party A did not write the name of the Rocket Research Institute, but only had a string of numbers code-729!

Lao Huang didn't bother with this matter.

Although it is not known what exactly this number code represents.

However, during this time, he also learned a little bit of the inside story through his relationship.

This is a super project with an initial investment of tens of billions of yuan.

Follow him, not to mention eating a brain full of fat, mixing a round belly, and having a good year is not a problem.

"I'll help you make these golden rods." After signing the contract, Lao Huang laughed and said. (End of chapter)
