Vol 19 Chapter 1148:

Everyone who engages in machinery hopes to have the best metal and the best workpieces in the world so that they can be assembled into the best machinery in the world.
But they are disappointed many times. They have not had the opportunity to obtain these good things. The performance of metals in the world has already reached a height that they think is very high, and it is very difficult to improve.
In other respects, it is almost impossible to achieve greater development.
Super large die forging machinery is a way to get more powerful workpiece performance in this world.
Mainly used for hot die forging and isothermal superplastic forming of difficult to deform materials such as aluminum alloy, titanium alloy, high temperature alloy, powder alloy, etc. Through forging, not only the shape of mechanical parts can 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 strength, the stronger the parts.
Under this premise, the one-time cost of using this machine is very expensive. Using the power of the entire volcano to pour the power of the entire volcano into this huge machine at the same time to carry out the work of the workpiece, this is the idea of ​​a madman.
In this huge volcano, there is already an automatic feeding and discharging import and export. It is impossible for humans to go to this place. The temperature inside ranges from hundreds to thousands of degrees. It is in the most central position. It is the core of this super die forging machine, a device that uses magma.
Now there are many small cars on the steel rails outside, and these are the parts they want.
It is a small car, but people are really shocked to see the small car that is tens of meters long.
The car is now holding groups of propeller blades. The huge blades weigh more than 60 tons. The car is slowly coming out of the huge super alloy propeller blades.
The heat wave is tumbling, and the blades have been fully automatically quenched, normalized, and tempered. The final forming process has reached the final stage.
This last stage is actually quite boring, and it takes time to slowly eliminate his residual stress.
This is a very time-consuming task, but it must 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 allowed to bring only one monitor.
They are all very professional. They carefully looked at the huge propeller blades in front of them, and were deeply shocked. They needed to measure the specific data and complete all the data analysis. Some experts followed carefully and the conclusions were very good. It's shocking.
The huge, super huge propeller blades in front of them completely surpassed the propeller blades used by modern aircraft carriers.
Unlike the propeller of an aircraft carrier, it only needs efficiency, but the size of the propeller in front of them is huge enough, and the mechanical performance is even more exaggerated. When they looked at the data shown above, they didn't know what to say.
"Propeller blade mechanical performance..." The expert just talked about it, and the purchaser next to him said directly: "Just tell me how much the performance will be improved compared to the No. 714 propeller we are currently using for ocean voyages. How much fuel is saved and how much is the rate of increase."
He only wants the final data. He can understand those performance aspects, but he does not want to listen. He already feels that today is a battle here. What effect the propeller had just now was not clear, but he heard clearly. What's more, this thing is used on aircraft carriers of the same level, which means that the quality of this propeller is the world's top.
When Si Fan called them, the offer was not so exaggerated.
One propeller of the aircraft carrier is enough to buy half of their ship.
Now this grade of propeller was released by Si Fan, and the price would be the same as the one given by him if he quoted it.
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 two knots. The most important thing is the use time. The use of the propeller is five times the previous one."
In a few words, there was not much consideration at all. The buyer next to him said, "I want 20 sets of general-purpose propellers for 100,000-ton cargo ships."
This seemed to be a starting point, everyone started to make noise, and Si Fan's mouth was almost grinning.
When this propeller was manufactured, Si Fan had already obtained the patent authorization from the American propeller manufacturing giant, and all patent blockades were broken by Si Fan. Now it can be sold casually.
So he waved his hand very happily.
Behind him came a group of beauties. They would correspond to the language of the country and directly asked about the purchase quantity in the past.
This number is quite exaggerated. In some ordinary countries, there are dozens or hundreds of small peasants, and those large countries make decisions on the spot.
Si Fanle blossomed. The cost of making such a propeller was less than one-tenth, and it took no more than half an hour to make it. Now it is selling at such a high price.
However, he has a good mentality. This is because his current technology is completely crushed. UU Reading www.uukanshu.com has surpassed several times in the world. Only then has the current profitability been achieved. That is absolutely necessary. The suppression of an era should be. Generate a hundredfold profit.
Si Fan is working hard, trying to restrain his smile, such a moment is not the kind of time that he says he wants infinitely, just the order that has been placed has reached four or five billion in funds, and there is no deposit at all. Anxious, these people are all representing the country, as long as they sign the agreement, they can't run away.
Waiting for them to have started signing, Si Fan was very happy. The workload of these months was enough.
Of course, this includes those who want unlimited goods.
But he knew that these ordinary special steel alloy propellers were certainly sufficient for ordinary cargo ships.
But if you want to upgrade the military ships, you are a little reluctant. The overall performance of their military ships does not have a big difference, and they do not need to be replaced 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 the other side is completed and his steel reaches a better level, he can forge better propellers, and he will definitely make a fortune.
The common people have to calculate the cost of these money, and they need to calculate the cost of using it.
But military ships have an advantage. There is always a country behind them that can accept higher premiums.
The intensity of their acceptance is a bit exaggerated. After all, people’s ships are used for warfare. If it is a propeller that can hide a submarine, it may be more expensive than a ship.
