"If only we could build a ship like this! Then you can really dominate the world! ”

"Yes, strong ships and cannons, invincible opponents all over the world......"

"Don't you want that if you're not happy?"

"Doesn't have to? The flying clipper next to it was already invincible. ”

"Yes, yes, it's more realistic to build an iron-hulled flying clipper sailboat......"

"But it's still the steam ironclad that pulls some ......"

Obviously, the topic raised by Holley immediately attracted everyone's attention, and the onlookers looked around, looking at the huge hull of the Nicole and expressing their feelings.

"Sister Wang, listen to Sister Nicole, you are an engineer from Jiangbei Shipyard, and you are the top professional in our group!"

"Wang Gong, do you think we will be able to build such a free wheel in many years?"

Everyone looked around and came back, and followed Huali to ask questions to this professional, Wang Xue bowed her head to everyone and muttered for a long time, then raised her head and whispered to everyone:

"Well, one thing is for sure, no matter how hard we try to light up the tech tree, we will definitely not be able to build it in the next three or five years! In fact, it is difficult to say ten years from now...... Well, twenty years from now, maybe it will work...... Actually, to be exact, it's not that you can't build it, but you don't dare to build it! ”

"What does it mean not to dare to make?"

Wang Xue's last sentence immediately caused everyone's puzzlement.

"Is it because the technical conditions are not enough, are you afraid that the quality of the manufacturing will not be up to par?"

So someone in the surrounding melon-eating crowd asked.

"I mean, for our current industrial level as a whole, even if we have completely exhausted the craftsmanship, I am afraid that in terms of the industrial base of that new world, we will not be able to support the manufacture of ships of such large tonnage. At least for quite some time. ”

Wang Gong looked at the tall building of the Nicole and shook his head slightly in response.

"Why? I heard that our small blast furnace and micro rolling line are still very good, although the amount of steel tapping is very small, can't it add up to a lot? ”

Someone in the crowd asked, puzzled.

"It's not a matter of quantity, it's a question of the quality of the metal. Hey, let me ask you, do any of you know how the Titanic sank? ”

At this time, Wang Xue glanced at the questioner and asked rhetorically.

"It's hit the iceberg, who doesn't know this?"

"To be exact, hitting the iceberg and then the hull steel plate was cut by the iceberg with a long gap, causing several cabins to enter the water at the same time!"

"Is it because the tonnage is too big?"

"The inertia is large, and the impact force is naturally ......"

Someone in the crowd added.

"What you said is close to the truth, but the large tonnage and large impact kinetic energy are only one of the reasons, but have you ever thought about it, isn't it strange that the water can make a long hole in the thick steel plate after it freezes?"

"Shouldn't it?"

"Well, if you exclude the huge impact kinetic energy, the fact that the steel plate was cut so long by the ice cube is weird!"

"Is there some quality scandal?"

Someone in the crowd asked.

"The scandal is not a big deal, the main reason is that the world at that time, the entire steel industry, had not yet noticed an important problem: steel with high sulfur and phosphorus content sailing in ice water for a long time will cause the material to become brittle, the scientific name is cold brittle. I can't say this question clearly for a while, hey, Holley is an expert in this area, he must be clear......"

Wang Xue said to the onlookers in a light tone.

"So, will the steel we make in the future also have too high sulfur and phosphorus content?"

This topic has more and more people gathered around.

"Well, it depends on the level of steelmaking technology, right? Ask the experts in this area! ”

"Holley, you are a steel mill technician, and this question should be answered by you."

"Yes, please explain to us how to control the sulfur and phosphorus content of ship steel."

Wang Xue passed the ball to Holley.

"To be honest, I really can't control it now, Wang Gong, don't stare at me, in fact, you also understand!

Although the process of desulfurization and dephosphorization is not too complicated, and the required excipients such as lime and oxygen are not difficult to prepare, there are two main aspects, one is the purity of lime, which is related to the chemical level, right? In addition, there is a lack of detection methods.

As for the purity issue, I have to ask our chemistry experts here, Mr. Zhao, they ......"

Hua Li looked back at a middle-aged man who was talking and laughing with Anna in the distance, then turned his face and continued:

"Mr. Zhao is a chemistry teacher, I heard that he is still a chemistry family, his ancestors are alchemists, and he also told me when chatting in the morning, because of the lack of sophisticated testing equipment, we can't accurately identify the composition of substances!

Sister Wang, how do I know what level of sulfur and phosphorus in this furnace of molten steel has reached? The only way is to accumulate experience, and if the origin of the raw material changes, or the batch changes, maybe you have to re-accumulate data, so it is very troublesome, in short, it takes time to accumulate. ”

Holley raised his voice and said to the crowd around him.

"Then why don't you give us precision testing equipment?"

Someone in the crowd asked.

"Anna's reason is also very good, he said that the equipment given to us is what we have the ability to copy, don't stare at me, this is what he said!

Therefore, he provides the technology and equipment that are sustainable and capable of self-renewal and self-development under the conditions of the new world.

Because Anna believes that once we are given precision testing equipment beyond our own capabilities, it is likely to produce some kind of dangerous and fragile dependence, after all, the overall industrial level and social productivity conditions of that era are limited, and if we want to achieve self-renewal in the new world, we should start from the basics and make steady progress step by step.

Therefore, equipment that is beyond our ability to copy is not only not helpful to us, but once a serious dependency develops, it is harmful to us! The consequences could be catastrophic......"

Holley's statement made the surroundings quiet for a while, and it took a while for someone to respond:

"What then? Do we have to start from scratch with this huge pile of industrial equipment? ”

"That's not true, but we definitely need to find a way to have some basic conditions before we can play the role of these industrial equipment."

Apparently someone in the crowd had some understanding of Anna's approach.

"Yes, so we can only selectively and gradually develop our industry according to the conditions of that era."

Before Holley finished speaking, someone in the crowd of onlookers eagerly asked:

"The question is how long will it take? Will I be able to use household appliances in my lifetime? As for computer networks or something, when will electrification be realized? ”

"Well, if you count it from the initial stage, it may be possible to develop it gradually, but within 10 years, there is certainly no certainty that full electrification will be achieved, and it is difficult to say in 20 years."

Holley replied simply.

When everyone listened, some shook their heads and sighed, and some nodded thoughtfully.

Holley, on the other hand, shrugged his shoulders and spread his hands, looked back at Nicole, who was chatting and laughing with Sun Lao and them on the top of the cockpit, and continued:

"So it's a systems engineering ......"

"But the medical equipment in the building is quite advanced, and it seems that it is difficult for us to replicate it, so why did we provide it?"

"Those medical equipment are not open to the public! Can it only be used for ourselves? ”

Xu Rou, the nurse standing next to her, immediately responded.

"You see, that's why you can't build a big ship like the Liberty Wheel."

Only then did Wang Xue answer to the person who asked the question just now and pulled the topic back.

"So, what kind of ship can we build? Don't tell me that you can only build wooden boats with this huge pile of industrial equipment! ”

Several young people in the crowd spoke a little deflated.

"Haha, then you are underestimating us, let me tell you, as long as the displacement of the ship designed by Sister Wang does not exceed three thousand tons, within ten years, you can use any kind of ship steel you want! That's what I can guarantee here! Of course, the cost is another story! ”

Hua Li smiled, and his face finally revealed some confidence.

"So? That should be reasonable, I remember how many tons of displacement was the Sea King three hundred years ago? ”

"It seems to be less than 2,000 tons, and it's still wood."

"Well, it's wooden, it looks like it has iron armor, right?"

"I remember that it was sixty or seventy meters long, more than ten meters wide, and the draft was five or six meters, well, it should have been a big ship in that era, and I heard that there were more than 100 cannons alone!"

"That kind of broken bronze front-loading cannon? The rate of fire is terrible slow, the effective range is less than two kilometers, and the shot is still a solid bullet, which is not our opponent at all! ”

"Let's put it this way, if we develop a hybrid iron sailing ship with a displacement of more than 1,000 tons, we can really dominate the seas!"

"yes, there's no problem with a ship like the Pride......"
