Cheng Kailong is not empty words.

He felt that with Wang Buan's contribution, there was no problem at all in winning a special medal.

The current leaders of the party and the state attach great importance to those who have made meritorious contributions. Definitely will not make the other party feel wronged.

It is a pity that Wang Buan is not a member of the army.

If he is a member of the army, he will directly be a first-class merit.

In peacetime, if you want to obtain first-class merit, the difficulty is definitely to the sky.

However, Cheng Kailong believes that Wang Buan has every reason to obtain first-class merit.

Of course, in line with the principle of keeping a low profile, the honor won by Wang Buan cannot be made public for the time being. As the saying goes, your name is unknown, and your deeds live on forever.

"How did you do that?" Cheng Kailong asked slowly.

"Confidentiality. Wang Buan shook his head slowly.

Of course, he can't say that this is technology from the planet Cybertron, not the people of the earth.

It's not that I don't want to say. Yes, there is no need to explain.

Also aliens?

Do you think I'm a three-year-old?

"Okay, please go ahead and help us make a few experiments. Cheng Kailong did not continue to ask.

"No problem. Wang Bu'an agreed.

He reached out and took the information.

All the data is stored in an encrypted USB flash drive.

This kind of USB flash drive uses a special password. If someone from the outside world wants to crack it, the USB flash drive will be automatically destroyed.

Cheng Kailong entered the password, and the USB flash drive opened smoothly.

The data starts to be transferred.

Robot Elf One examines all the data.

Immediately, machine number one began to start. A variety of alloys with different shapes and properties are produced in an orderly manner.

The heavy alloy ingots were then hoisted onto the workbench of the 100-million-ton hydraulic press.

The first thing to be forged is a flat alloy steel plate.

Both the length and width are five meters. Thickness ten centimeters.

The alloy ingots are placed on a large workbench.

The 100-million-ton hydraulic press then began to be forged. Fifty times of repeated forging.

For similar alloy plates, Cheng Kailong needs a total of fifty pieces.

Included in different thicknesses. There are 10 cm, 20 cm, 30 cm, 50 cm, etc.

They are all intended for testing. Including artillery shell shooting, aerial bomb bombing, and so on.

The main thing, of course, is to test the shooting of armor-piercing, depleted uranium shells.

Previous steel brazing has proven that the material used is very hard. None of the weapons can deal damage. However, the shape of the drill is too special to push oneself or the other.

After the alloy plate, it is a large and small composite alloy plate. Shapes and sizes. The thickness is also completely different.

Some are frontal armor of tanks, some are side armor.

Some are frontal armor of armored vehicles, some are side armor.

There are also tracks, load wheels for tanks, etc.

It is not only a test of the forging ability of the hydraulic press, but also a test of the processing ability of the multi-axis CNC linkage machine tool.

For example, the front armor of the tank was folded in several places. It is very difficult to process. There are strict regulations on inclination and angle. The difference is a millimeter, and it must not be sloppy.

Previous tanks, with an oval turret, were able to bounce through ordinary shells. But nothing can be done in the face of a new type of armor-piercing projectile.

Therefore, now the latest tanks, including the 99 modification, are all composite armor, and they are all polyhedron in appearance.

In addition to this, there is a set of high-power diesel engine blocks.

If I didn't guess wrong, it should have been the engine of the 99 change tank.

The previous 99 tank had an engine power of only 1200 horsepower. Later it was increased to 1500 horsepower.

The latest engines, however, are not perfect. The performance is not very stable and the reliability is insufficient. In many exercises or training, 99 has seen the phenomenon of lying on the nest.

As for the older Type 96, there are more cases of lying on the ground. At the end of the day, it's a question of engine reliability.

The processing of diesel engine cylinder block is more complex and requires a complete set of tools.

However, for 100 million tons of hydraulic press and ten-axis CNC linkage machine tools, it is actually a trivial matter.

There is no need for a main workbench at all. The sub-table is directly extruded.

Ten-axis linkage extrusion, easy and beautiful.

The material used is a secondary high-temperature corrosion-resistant alloy. The heavy pressure resistance is 3600 tons, the high temperature resistance is 3600 degrees, and the centrifugal force is 360 tons.

"What are you...... How many axes are linked?" Cheng Kailong asked curiously.

"Ten axes. Wang Buan replied honestly.

"So many?" Zhang Kailong looked stunned.

"In fact, it is an enhanced version of the five-axis CNC linkage, and each axis is divided into two. Wang Bu'an said in disguise.

"Oh. Cheng Kailong was finally reluctantly able to accept it.

Ten-axis linkage, so powerful.

Especially in the field of heavy industry, the difficulty of five-axis linkage is very high.

Five-axis linkage places high demands on sensitivity. Then, in terms of strength, it is naturally impossible to avoid some weakening. Therefore, it is okay to process small parts, but it is difficult to process large parts.

However, the crankshaft, propulsion shaft, propeller or something of the ship are all curved, and they must use five-axis CNC linkage.

At the same time, it also requires that the five-axis CNC linkage machine tool has a very strong force.

Otherwise, how can those behemoths that are often tens or hundreds of tons be easily cut into shape?

Wang Buan's hydraulic press is simply amazing.

"Make a propeller blade and see. Cheng Kailong took out the data at the bottom of the pressure box.

"Good. Wang Buan is still an understatement.

Robot Elf No. 1 reads the data.

The data shows that the requirements for this propeller blade are very high.

It is more than four meters long and weighs more than five tons.

Such a huge propeller, most of the time, is used on a 100,000-ton giant ship.

The general giant ship is a four-axle four-paddle structure. That's four propulsion shafts, four propellers. Only a very small number of them are six-axed and six-oared. That's six propulsion shafts, six propellers.

For forging propellers, the materials used are special. It can't be a general alloy. High-temperature corrosion-resistant alloys are also not suitable. It can only be some kind of very special copper alloy. For example, nickel, aluminum, beryllium, bronze alloy, etc. Otherwise, soaking under water all year round will cause various problems. For the surface of the copper alloy, special coatings are also used. It is best to have a certain toxicity to avoid entanglement of marine organisms.

For any country, the processing technology of propellers is the top. Regardless of cost, only quality.

Because of the high-speed rotation, the pressure and resistance are very large, and even a small bubble (called cavitation in the professional term) may cause irreversible damage to the propeller blades. Many of the propellers are so strong that they can't even be hurt by bullets, but they are scaled all over their bodies by small bubbles.

When forging propeller blades, cavitation damage must be taken into account.

Any blade needs to be forged and tempered repeatedly, and the quality must be achieved to the extreme.

Can Wang Buan do it?

Cheng Kailong's heart is actually bottomless.

"If you can't do it, don't force it. Cheng Kailong said with a mixture of gains and losses.

"It's fine. Wang Buan is very sure.

This is not the propeller of the hangma, the requirements are not so high.

Now he is ready to forge the propeller of the Hangma. There just wasn't a chance.

The raw material for forging the propeller, from machine number eight.

It mainly produces a variety of high-performance copper alloys.

Nickel-aluminum-copper alloy, combined with special metal elements such as beryllium, palladium, niobium, molybdenum, and chromium, is the best raw material for forging propellers.

A huge and heavy copper alloy came down the production line and was immediately hoisted.

It was placed on the main table of the 100-million-ton hydraulic press and forged repeatedly. The parameters set by Wang Buan are to be forged 500 times.

The copper alloy ingots are forged into a flat plate and then sent to table 2 for extrusion.

The ten-axis CNC linkage machine was started. Extrusion in one pass.

No cutting is required. No reprocessing is required.

After squeezing it many times in a row, and then polishing, the surface of the blade is very smooth.

The whole process takes less than twenty minutes.

Cheng Kailong looked at all this in disbelief.

What is it?

These are the propeller blades of a giant ship!

Generally speaking, its processing time takes at least one month. Or even three months.

However, Wang Bu'an only took twenty minutes.

Twenty minutes!

Extrusion in one go!

There is no need for correction or fine-tuning at all.

"You ......" Cheng Kailong wanted to say but stopped.

He has a lot of questions.

But I don't know where to start.

After all, he is not a professional. He just knows a little bit about everything. A real expert, and still on the way.

Because of the coincidence, Cheng Kailong unexpectedly became the first person to contact Wang Buan. In order to be in a hurry, he asked him to reach an agreement with Wang Bu'an as soon as possible, and strive to send samples for testing as much as possible. If the sample quality is qualified, it is necessary to order in large quantities. No, it's oversized batches. The number will be staggering.

In the past, we have fallen behind in too much schoolwork. Now, it must be made up.

However, is the quality really guaranteed at such a fast speed?

Let the data do the talking.

Seeing the night falling, the rain gradually stopped.

Two hours of rain is over.

The samples that Cheng Kailong needed were all ready.

A team of Dongfeng brand trucks hung up on the place to take pictures, pulled the tarpaulin, and slowly drove into the industrial park.

The drivers and escorts are dressed in civilian clothes. But anyone with a discerning eye can see it. They are all military men. That kind of long-trained temperament can't be concealed.

They are responsible for shipping all the samples away.

Some heavy samples also require large lifting machinery.

"Aren't you Cheng Fei's person, what do you want so many test subjects?" Wang Buan asked in a low voice of confusion.

"Did I say that I was Cheng Fei's person?" Cheng Kailong said solemnly.

"No......" Wang Buan shook his head slowly.
