Vol 8 Chapter 405:

Everyone who engages in machinery hopes to have the best metal and the best workpiece in the world, so that they can be assembled into the best machinery in the world.
But many times they are disappointed. They don't have the opportunity to get these good things. The performance of the metals in the world has already reached a height that they think is very high. It is very difficult to improve.
In other respects, it is almost impossible to achieve greater development.
Very large die forging machinery is one 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. By forging, not only the shape of the 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 earlier the parts become more powerful.
Under this premise, the one-time cost of using this machine is very expensive. It uses the power of the entire volcano to pour into this huge machine at the same time to perform the work of the workpiece. This is a crazy idea.
In this huge volcano, there is already an inlet and outlet for automatic feeding and discharging. It is impossible for humans to go there. The temperature inside ranges from hundreds to thousands of degrees, and it is at the most central position. It is the core of this super die forging machine, a device using magma.
Cars are constantly appearing on the steel rails outside. This is the part they want.
It is a car, but people really shocked when they saw the car that was tens of meters long.
On this car are now a set of propeller blades. The huge blades weigh more than sixty tons, and the small vehicle slowly comes out with this huge super alloy propeller blade.
The heat wave tumbles, and the blades have undergone full-automatic quenching, normalizing, and tempering processes, and have reached the final stage in the final forming process.
This last stage is actually quite confusing, and time needs to be taken slowly to eliminate his residual stress.
This is a very time-consuming thing, but it must also be done.
Si Fan stood in front, with a group of scientists at the back, and then there were purchasers from all countries, and each person was allowed to bring only one monitor.
They are all very professional. They looked at the huge propeller blades in front of them and were deeply shocked. They needed to measure the specific data in them and complete all the data analysis. The experts who followed followed a careful analysis, and the conclusions were very 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, he only needs efficiency, but the propeller in front of him is already huge enough, and the mechanical performance is even more exaggerated. When looking at the data shown above, they have no idea what to say.
"In terms of the mechanical properties of the propeller blades ..." The expert just had to talk about it, and the purchaser beside him said directly: "You can directly tell me how much the performance of the propeller No. 714 we are using will be improved. How much fuel you save, how much you increase. "
He only wants the final data. He can understand the performance, but he doesn't want to hear it. He already feels that it is a battle to come here today. The effect of the propeller just now is not clear, but he heard it clearly. In fact, this thing is used in aircraft carriers with a grade, which means that the quality of this propeller is the highest in the world.
And when Si Fan originally called them to come, the offer was not so exaggerated.
One propeller of the aircraft carrier is enough to buy half of them.
Now the propellers of this grade are released by Si Fan. If the price is based on his price, it is the same as Baiji.
Experts calculated and said: "The fuel saving is about 40%. The specific value needs to be tested. The sailing speed can increase by about two knots. The most important thing is the use time. This propeller uses the top five before."
In a few words, there was not much consideration at all, and the buyer next to him said: "I want 20 sets of general propellers for 100,000-ton cargo ships."
This seems to be a starting point, everyone is noisy, Si Fan's laughing mouth is almost at the root of his ears.
At the time of this propeller manufacture, Sifan had already obtained the patent authorization of the giant propeller manufacturing company, and all patent blockades were breached by Sifan. Can now be sold casually.
So he waved very happily.
Behind him came a group of beauties, who would correspond to the language of the country and directly ask the purchase amount in the face of them.
This number is more exaggerated. Some ordinary countries have small peas and large countries. There are dozens or hundreds of them. Those large countries make a decision on the spot, how much is required.
Sfanler blossomed, and the cost of making such a propeller was less than one-tenth ~ EbookFREE.me ~ It took less than half an hour to make it, and he could get it now, selling such high prices.
However, he has a lot of mentality. This is because his current technology is completely crushed and has surpassed several times in the world. This is the current profit. It is absolutely necessary. The suppression of an era should generate a hundred times the profit.
Si Fan is working hard, trying to restrain his smile. After a while, he does n’t count the kind of people who say he wants unlimitedly. The orders that have just been placed have reached a total of 45 billion yuan. There is no need for deposits. Anxious, these people represent the country, as long as they sign the agreement, they can't run away.
Waiting for them to start signing, Si Fan couldn't be happier. The workload of these months was enough.
Of course, this includes those with unlimited demand.
But he knew that these ordinary special steel alloy propellers were certainly enough for ordinary cargo ships.
However, it is a bit reluctant to upgrade military ships. The overall performance of their military ships does not have a huge gap and does not need to be replaced at one time.
But what if Sifan had better propellers?
For Si Fan, this is very simple. As long as the smelting center on the other side is done and his steel reaches a better level, he can forge a better propeller, and he will certainly get rich by then.
These people have to calculate the cost of these money, they need to calculate the cost of use.
But military ships have the advantage that they always have a country behind them that can accept a higher premium.
The intensity they accept is a bit exaggerated. After all, other people ’s ships are used for fighting. If it is a propeller that can make the submarine invisible, the price may be even more expensive than the ship.
