Open an aircraft carrier to fight against Japan

Lin Yuan ordered someone to call them in, and it was indeed those two people. Before Lin Yuan could speak, one of them said, "My name is Jenningson Brown, the chairman of the Armstrong factory in the UK."

Another said: "My name is Dwight Lee, chief technical consultant of the Armstrong factory in the UK."

The Armstrong Factory was a well-known military factory in this era. The warships and artillery it produced were famous far and wide. Many artillery pieces of the Qing court were purchased from this factory.

Many weapons and equipment in the UK are purchased from the Armstrong factory. People who can sell the arms to the government are very well-informed. That's the case with Jenningson. Because of the relationship with the mysterious ship, he wanted to see Lin Yuan, but the United Kingdom declared neutrality, and it would be inconvenient to go directly, so he funded the investigation team and led to this investigation.

The important reason for coming here secretly is: they don't want their competitors to know their actions. The competitor of Armstrong's company is the famous Krupp company.

In this era, companies with advanced artillery technology have mastered advanced steelmaking technology without exception, because the performance of the steel used to make artillery directly determines how much explosive power the gun body can withstand. Farther away, the shells can also be made larger, and the lethality will be stronger.

When Jenningson heard about the mysterious ship, he immediately discussed it with Dwight, and Dwight keenly realized that the length of the mysterious ship was more than 300 meters, which put forward high requirements for its structural steel, at least its yield The strength is much higher than the steel produced by our own factory.

So they thought: If they get the technology to make this kind of steel, they can leave their business competitors far behind!

Lin Yuan knew their identities and probably guessed that they came for advanced technology, but he deliberately pretended to be confused and asked, "Do you have anything to do?"

Jen Ningsen, who has been in the business field for many years, knows that he can't come up and talk about the mysterious ship. He said: "I heard that General Lin is very knowledgeable about technology. We really want to come and talk to General Lin."

Lin Yuan asked, "Who did you listen to?"

Dwight smiled and said, "You built a steel factory when you were in Ryukyu, and our people heard about it from there."

Lin Yuan replied: "Oh, so that's the case, what do you want to talk to me about?"

Dwight asked: "I don't know how much General Lin knows about steel smelting?"

When Lin Yuan heard it, he thought to himself: "It seems that the guess is right, it really is for the technology." Lin Yuan knew that being humble is the best way to show off, so he said humbly: "Well, understanding is out of the question, Just know a little bit."

Science and technology, the more you learn, the more you feel that you don’t know much about it. Those who say they know everything are ignorant. Lin Yuan’s words convinced Dwight that Lin Yuan Far really does many things.Dwight asked, "So can you talk about how to increase the strength of the material?"

Lin Yuan said: "I'm sorry, please forgive me for not being able to answer your question. The scope of your question is too broad, and there are too many types of materials. Do you mean metal materials? Or non-metal materials? The strength is also different. , you mean yield strength? Or fatigue strength?"

Dwight actually set a trap in the question. If Lin Yuan answered the question directly and boastfully, it means that Lin Yuan doesn't understand anything at all.

Dwight couldn't help but nodded when he heard Lin Yuan say this, and said, "I'm sorry, I didn't ask clearly. I want to ask about the yield strength of steel."

Lin Yuan smiled and said, "It is necessary to reduce the content of harmful elements."

Jenningson rushed to ask: "How to reduce the content of harmful elements?"

Lin Yuan smiled and said: "The most harmful element is sulfur. When the content of sulfur exceeds a certain limit, steel is prone to cracks during rolling or forging. Sulfur is generally doped in iron ore and coke. Inside, it is difficult to remove them before entering the blast furnace. If you want to make high-quality steel, you must remove the sulfur element before the molten iron enters the steelmaking furnace. The method of reducing the sulfur element..."

At this point, Lin Yuan stopped talking. He turned to look at Dwight, and said with a smile, "Mr. Dwight must know more than I do." The deposit certificates of the Imperial HSBC Bank are 20 pounds in total, which is equivalent to more than 100 million taels of silver in your country. If General Lin tells us the refining method of fine steel, the 20 pounds will be offered with both hands!"

Lin Yuan thought to himself: "What's the matter today, there are actually two people who have been taken advantage of and sent to the door, and they are so generous! With this money, the development and construction below will be much more convenient!" Lin Yuan pretended to be surprised With an open look, Qian said, "Okay, okay, I'll just say it!"

Lin Yuan said: "Sulfur is mainly brought in by coke, so it is a good way to reduce the coke needed for ironmaking, but this road is very difficult, we can only find a way in the process of smelting, by material Conservation We can know that sulfur will exist in molten iron and slag. If we can make the slag absorb as much sulfur as possible, then we can reduce the sulfur in the molten iron and add more alkaline oxidation in the slag. It is a good way.” “But this is not enough to remove all the sulfur elements, so we need to refine it when the molten iron flows out of the blast furnace. For example, we add a certain amount of soda ash to the molten iron. Remove 80.00% of sulfur in pig iron!"

Dwight said: "Your opinion is very good, but what you said is at the principle level, what we need is at the production level, can you provide us with a detailed process flow? What we want is very specific, such as Where do the basic oxides absorb sulfur in the blast furnace?"

Lin Yuan nodded and smiled and said, "Okay, no problem." As soon as they left, Lin Yuan contacted Liu Jinqiu, a metallurgical expert on the Beijing ship. Liu Jinqiu was currently in the iron and steel plant in Ryukyu. Said: "Those two British people are not stupid, are they? Although hot metal desulfurization is very important, it is not worth 100 million taels of silver!"

Lin Yuan smiled and said: "I have been confused about this matter for a long time, and then I figured it out. They really have other plans. If you are like this, please give me a technical document as soon as possible. The specific requirements are as follows..."

The next night, as soon as the investigation was over, the two Britons got into Lin Yuan's tent. Lin Yuan handed them the technical information he had copied all night, and they couldn't wait to read it. It was getting brighter and brighter, but Jenningson's eyes were getting uglier!Lin Yuan thought to himself: "Why do these two people have completely different reactions?"

The two finally finished reading the materials, looked at each other, and found an excuse to go out. Lin Yuan listened with pricked ears at the edge of the tent. Jenningson seemed very excited, and he said, "Are you crazy? We all know the craftsmanship on it I know, and our coke contains little sulfur, so we don’t need to spend 20 yuan to buy this thing!”

Dwight's voice was also very anxious, he said: "Why is it unnecessary! Besides those crafts, there are more things we want!"
