The construction of pure iron armored warships requires a lot of technology and high.
Relying on traditional welding technology, 100% water leakage.
The current welding is still at the stage of casting welding, segment welding, etc. The temperature is low, the energy is not concentrated, and it is impossible to weld large areas and long welds.
On the surface, the place where this welding technique welds is also melted together.
But if you take a photo with a microscope, you can find that there are a lot of bubbles, crevices, cracks, and faults in the welding place.
These problems have no effect at all in normal times.
But under the impact of huge pressure, or the corrosion of seawater, problems will soon occur.
If you want to build an iron armored ship, you must pass the welding test.
The best is of course argon arc welding. Unfortunately, argon arc welding requires electricity, which is a bit difficult.
At present, the most suitable method is to use oxyacetylene to increase the flame temperature by increasing the ratio of oxygen.
As for oxygen, the people in this university hall have been separated, and it can also be produced on a small scale.
These are still related supporting technologies, and the core is actually the steam engine.
As long as the power of the steam engine is increased, other supporting technologies are relatively easy.
It is really difficult to expect Feng Xianzhong and the others to build a super high temperature and high pressure steam engine in such a short time.
If Feng Xianzhong can build a super high temperature and high pressure steam engine within two or three years, then he is definitely not a genius, he is definitely a traverser, and he must be arrested and tortured.
To upgrade technology by leaps and bounds, you still have to rely on traversers, even systematic traversers.
Therefore, Wu Changqing made a blood purchase.
It took 1 million technology points to purchase high temperature and high pressure cylinder manufacturing technology, and 300,000 yuan to purchase related supporting technology.
This is not enough. The manufacturing process alone is useless. The key to the high temperature and high pressure cylinder is the alloy material.
The materials are not good enough, everything is empty talk.
Therefore, Wu Changqing spent another 800,000 resource points to purchase a large number of raw materials for manufacturing high-temperature and high-pressure cylinders.
One part of these raw materials is used for manufacturing, and the other part is used to study the ingredients, and then obtain the raw material formula and the formula ratio, so as to master the technology of manufacturing this material.
Owning the finished product, and then obtaining the formula in the reverse direction, it is absolutely possible for the scientific researcher to faint happily. Compared with purposeless groping and trying, this method of reverse research formula is countless times easier.
In addition to the steam engine technology, Wu Changqing also purchased the related technology of the rifled gun.
On the armored ship, the smoothbore gun continued to be used, and I always felt that some style of painting did not match, and it was more appropriate to match the rifled gun.
Of course, it is only suitable for Dahua, but quite inappropriate for the navies of other countries.
Use wooden sailboats and rifled guns to fight against iron-clad ships and rifled guns. After foreign navies encounter them, they will regret choosing the profession of navy.
After buying some blood, 1.6 million technology points and 900,000 resource points will be consumed.
Host: Wu Changqing.
The current territorial area is 1.2 million square kilometers, the total resource points are 36 million, and the remaining 33.5 million.
The current area has a population of 72.4 million, a total of 72.4 million technological points, and the remaining 48.32 million.
Although it took a lot, the total amount has also increased significantly due to the sudden increase in the site some time ago.
In addition, because of the habit of diligence and thrift, Wu Changqing's resources are still in a very sufficient state.
Just like old farmers with huge deposits, they are reluctant to withdraw money when they are not in special need. On the surface, the clothes are in tatters, but the thief has money in his pocket.
Wu Changqing worked hard to sort out these exchanged resources and materials, and sent someone to Feng Xianzhong's hands.
After getting these things, Feng Xianzhong was messy in the wind, and his mood at the moment was complicated.
"Suddenly I found myself really good and useless. Apart from waiting for the teacher's guidance, I have not had any breakthrough research results."
Feng Xianzhong sighed.
People around him admire his IQ, because his research on technology is deep enough.
If he listens to this kind of praise too much, he will also increase his requirements for himself, hoping that he can study some major results to prove that he is worthy of these evaluations.
But the reality is always cruel. Every time a research encounters a bottleneck, he needs Wu Changqing's guidance.
"Teacher Feng, you are trying to make a mistake. A useless person, how can you be qualified to be pointed out by your majesty? Even if these things were not researched by your teacher, you are the specific person in charge. You can only use your majesty’s research results quickly. It is also a great talent to digest and apply it to practice.
In the whole world, there are no more than five fingers. As for your Majesty, why should we compare it with the wise and martial god, the unparalleled **** emperor, your Majesty is the reincarnation of a real dragon, we are just mortals. "
Feng Xianzhong's assistant persuaded.
Anyway, he has already accepted his fate, and he can compare with anyone, but he won't compare with Wu Changqing.
Compared with Wu Changqing, it is arrogant and arrogant.
"What's more terrifying is that your Majesty usually handles official duties. I am afraid that these studies will be conducted in his spare time.
"Maybe, your Majesty is thinking in a dream."
"The world's knowledge, I'm afraid all is in your majesty's mind."
Others followed suit.
It stands to reason that these people engaged in scientific research should not be superstitious.
However, some things about Wu Changqing are too weird. They can't explain this phenomenon according to the conventional way of understanding, so they can only interpret it in an unconventional way.
If Wu Changqing is not the emperor, they can still viciously suspect that these research results are actually someone else's, but Wu Changqing used his power to gain his own reputation in order to gain fame.
But Wu Changqing was the emperor. They didn't dare to think like that, let alone speak out, otherwise they would be insulting.
"Oh, it seems that I only have such a role. Tell everyone to stay up late tonight, understand your majesty's research results, and don't delay your majesty's major events."
Feng Xianzhong sighed.
He is not as open as an assistant. After all, he is a genius. How can a genius convince others so easily.
The real geniuses have quite strong pride.
However, as the number of times being crushed by Wu Changqing increased, Feng Xianzhong was almost convinced.
If you refuse to accept it, the reality is right before you.
No matter how hard he tried, he still couldn't catch up with Wu Changqing.
He couldn't even see how much knowledge Wu Changqing had mastered, let alone catching up.
When Feng Xianzhong asked everyone to stay up late, everyone wanted to cry without tears.
Although doing scientific research has high welfare and good remuneration, it is also very fortunate and consumes energy.
People who are not very young have started to lose their hair.
