Everyone who is engaged in machinery wants to have the best metal in the world, the best workpiece, so that it can be assembled into the best machinery in the world.

But many of them are disappointed, they don't have the opportunity to get these good things, the performance of the world's metals has reached a high level that they think is very high, and it is very difficult to improve it.

In other areas, it is almost impossible to achieve greater development.

Oversized die forging machines are one way to achieve more powerful workpiece performance in the world.

It is mainly used for hot die forging and isothermal superplastic forming of hard-to-deform materials such as aluminum alloy, titanium alloy, high-temperature alloy, powder alloy, etc. Through forging, not only can the shape of mechanical parts be obtained, but also the internal structure of the metal can be improved, and the mechanical and physical properties of the metal can be improved.

Under the premise of this requirement, the higher the force, the more powerful the parts are.

Under this premise, the cost of using this machine is very expensive, and it is a madman's idea to use the power of the entire volcano to pour into this huge machine at the same time to work on the workpiece.

In the middle of this huge volcano, there is already an automatic feeding and discharging inlet and outlet below, this place is impossible for humans to go to, the temperature inside ranges from hundreds to thousands of degrees, and in the most central position is the core of this super forging machine, a device that uses magma.

Now on the steel rails outside, there are constantly small cars, and these are the parts they want.

It is said that it is a car, but when you really see the car that is dozens of meters long, people are still quite shocked.

What is now on this car is a group of propeller blades, the huge propellers weigh more than 60 tons, and the car carries this huge super alloy propeller blades out slowly.

The heat wave is rolling, and the paddle has gone through the processes of automatic quenching, normalizing, tempering, etc., and has reached the final stage in the final molding process.

This last stage is actually quite pitiful, and it takes time to slowly eliminate his residual stress.

It's a very time-consuming thing to do, but it has to be done.

Si Fan stood in the front, a group of scientists in the back, and then there were procurement personnel from various countries, and each person was only allowed to bring one monitor with him.

They are very professional, carefully looking at the huge propeller blades in front of them, deeply shocked, they need to measure the specific data, complete all the data analysis, followed by some experts carefully analyzed, and the conclusions obtained are very shocking.

The huge, super-huge propeller blades in front of them completely surpass the propeller blades used in modern aircraft carriers.

Unlike the propeller of the aircraft carrier, he only needs efficiency, but the size of the propeller in front of him is huge enough, and the mechanical properties are even more exaggerated, and when they look at the data displayed above, they no longer know what to say.

"In terms of the mechanical properties of propeller blades, ......" the expert was just about to talk about it, and the procurement staff next to him said directly: "You can directly tell me how much the performance of the 714 propeller we are using now will be improved, how much fuel will be saved and how much speed will be increased when used for ocean voyages." ”

He only wants the final data, he can understand those performance aspects, but he doesn't want to listen to it, he already feels that it is a bloody battle here today, what effect this propeller has just now I didn't hear clearly, but he heard one thing clearly, this thing is used on aircraft carriers are all a level, that is to say, the quality of this propeller is the world's top.

And when Si Fan called them to come, the offer was not so exaggerated.

One propeller of the aircraft carrier was enough to buy them half a ship.

Now that this level of propeller has been released by Si Fan, if the price is according to his quotation, it will be the same as Bai Zhi.

The expert calculated and said: "The fuel saving is about 40%, the specific value needs to be tested, the sailing speed can be increased by about two knots, and the most important thing is the use time, the propeller is used for a maximum of five times." ”

In a few words, there was not much consideration at all, and the purchaser next to him said: "I want 20 sets of universal propellers for 100,000-ton cargo ships." ”

This seemed to be a starting point, everyone began to make noise, and the corners of Si Fan's mouth were almost grinning to the root of his ears.

At the time of the manufacture of this propeller, Si Fan had already obtained the patent authorization of the propeller manufacturing giant in the United States, and all the patent blockades were broken by Si Fan. Now you can sell as you like.

So he waved his hand very happily.

Behind him comes a group of beauties, who will correspond to the language of the country, facing them in the past to ask directly about the number of purchases.

This number is relatively exaggerated, some ordinary countries are dozens or hundreds of small bean and big countries, and those large countries make decisions on the spot, as many as they want.

Si Fanle blossomed, the cost of making such a propeller was less than one-tenth, and the manufacturing time did not exceed half an hour, and it could be done, and now it is sold at such a high price.

However, he has a mental number, this is because his current technology is completely crushed, surpassing several eras in the world, so he has the current profit, which is absolutely right, and the suppression of an era should produce a hundredfold profit.

Si Fan is working hard, trying to restrain his smile, such a short time is not the kind of person who says that he wants infinitely, just the order that has been placed is enough to reach four or five billion funds, there is no need to worry about the deposit, these people are all on behalf of the country, as long as they sign the agreement, they can't run.

Waiting for them to start signing, Si Fan couldn't be happy, the workload in the past few months was enough.

Of course, this includes those that are unlimited.

It's just that he knows that these propellers made of ordinary special steel alloys are certainly enough for ordinary cargo ships.

But if you want to upgrade your military ships, it's a bit reluctant, and the overall performance of their military ships is not far behind, and they don't need to be replaced all at once.

But what if Si Fan had a better propeller?

For Si Fan, this is very simple, as long as the smelting center on that side is done and his steel reaches a better level, then he can forge a better propeller, and he will definitely get rich at that time.

The people's money, they have to calculate the cost, need to calculate the cost of use.

But there is only one benefit to military ships, and behind them there is always a country that can accept a higher premium.

The intensity of their acceptance is somewhat exaggerated. After all, other people's ships are used to fight, and if it is a propeller that can make a submarine stealthy, the price may be even more expensive than a ship.
