Great Power Industry: You're a private company building an aircraft carrier?

“This patented technology from the East reduces evaporation by one-third compared to ours! If our customers knew…” Felix paused here, sweat pouring down his back.

They certainly understand their customers' needs, and their pursuit of higher natural evaporation rates is endless!

A 135,000 cubic meter liquefied gas ship with a natural evaporation rate of 0.15% means that it will lose 202 cubic meters every day. This is not the volume of the gas, but the volume after liquefaction!

The density of liquefied petroleum gas (LPG) is only about half that of water, which means that about 100 tons of LPG are lost every day!

Although a dual-fuel engine is used, it cannot burn that much liquefied gas in a day. The rest can only continue to be emitted into the air. If the natural evaporation rate is reduced to 0.1%, it will be just enough!

That's right, that's the critical threshold!

It's easy to imagine that customers will definitely gravitate towards this kind of performance in the future! As long as the first batch of liquefied gas carriers built by Dongfang are of reliable quality and do not cause any major accidents, then customers all over the world will use Dongfang's technology patents!

"Can we find similar materials?" Pierre asked seriously.

François shook his head: "We've tried many materials, but none of them can achieve this effect. I really don't know how the Easterners found it. It's very difficult for us to find similar materials."

It took the French over a decade to find suitable materials for the transition from NO.96 to NO.96-L03. Now, the Easterners have found them all at once, completely blocking their path to further improvement.

"A bunch of useless trash!" Pierre couldn't help but curse. "In the field of liquefied gas ships, we were clearly the strongest, so how did we suddenly get surpassed by the Easterners!"

They've been deeply involved in this field for decades! They've always believed they were the strongest, so how can they be at ease now that they've been surpassed by Easterners!

"The East has only just entered this field. Even if they've found the materials for the insulated tanks of the liquid cargo fencing system, it doesn't mean they possess the most advanced technology." François was still unconvinced: "It's a massive system; they simply can't do it right. They can't even handle a basic connector..."

The system for storing goods at low temperatures is a massive undertaking. People from the East have only just begun to explore this field, so how could they possibly manage it well?

"Report!" Just then, another experimental team came up: "We conducted experiments based on the connector technology that Dongfang has applied for a patent on. Their connectors have a thermal expansion and contraction rate that is 10 percent lower than our existing ones!"

what?

The Invar steel inside the liquid cargo containment system is a thin sheet. It also needs support to be firmly connected to the hull. The connection between metals will inevitably involve heat transfer. If it is not controlled, the entire ship will eventually become as hot as liquefied gas.

At this point, special connectors are needed!

This connector may seem insignificant, but it's crucial!

Unexpectedly, the connectors made by Dongfang using multiple materials have such performance!

"Even if they had connectors, they didn't have automatic welding machines. A liquefied gas ship with over a hundred kilometers of welds—I just don't believe that Easterners could weld that by hand!" François remained defiant.

“We don’t know if Dongfang has automatic welding machines for liquefied gas carriers, but we’ve already seen them using automatic welding technology to weld hulls at the Dongfang Laiyang Group’s shipyard.” Pierre sighed, “I never expected that this Laiyang Group would suddenly rise to prominence!”

It's so frustrating!

"What? They already have automated welding for shipbuilding?" François was quite surprised.

"That's right. If the intelligence analysis is correct, the ship in Laiyang Group's shipyard is very likely an aircraft carrier."

Aircraft carrier! The most powerful combat weapon at sea! For a country, possessing an aircraft carrier is the greatest pride; for a shipyard, being able to build an aircraft carrier is the greatest honor! It also represents the shipyard's formidable strength!

If Laiyang Group can build aircraft carriers, then its ability to build liquefied gas carriers will also be convincing!

François's expression was complicated. Had we really been outdone?

Pierre sighed, then looked at Felix: "Get ready, we're going to the East."

"What to do?"

"Let's negotiate with the Easterners. If they can sell us these patents, we'll agree to any price they ask for!"

If you can compete, then compete; if you can't, then buy out your competitors! That's how simple and direct things are in the world of capital!

"What if they refuse?"

Pierre smiled and said, "Laiyang Group does all kinds of business around the world. That President Qin is also very smart. He knows how to make the right choice."

East.

A sneeze!

Qin Chuan sneezed.

"Brother Chuan, are you alright?" Yang Xue asked with concern.

"It's nothing. I guess my uncle is talking about me behind my back. Sigh, I can't just sit back and do nothing. I have to go and see how the recycling of the titanium alloy is going."

Laiyang Group was highly efficient. Within a few days, the non-pressure hull of the 945 nuclear submarine was dismantled, and part of the pressure hull inside was also removed. After cleaning, it was taken by Wang Chongyang for smelting experiments.

The entire processing technology has been handed over to Wang Chongyang, but he still needs to become proficient in the operation before he can fully master it.

Metallurgical workshop.

Wang Chongyang has requisitioned the 100-ton vacuum smelting furnace, where vacuum self-consumption smelting is underway.

"Professor Wang, the vacuum self-consumable melting process is complete!"

"Okay, according to the process requirements, cast it into an ingot, and then forge it on a 10,000-ton forging press at 1050 degrees Celsius!"

"Yes!"

Boom!

In just one stroke, the ingot was pressed into a large pancake.

"Continue the forging process, using a box-type resistance furnace, heat it to 750 degrees Celsius, and continue the forging!"

After saying that, Wang Chongyang thought of something else: "Cut off a piece and observe the initial a phase inside!"

For titanium alloys, it is not only necessary to remove various impurities and add some metallic elements, but the most important thing is the growth of the internal α+β two-phase region!

Now, the first batch is being tested, and we need to observe the results of each operation.

Heated to a fixed temperature, then cooled, annealed to a fixed temperature, and then fed into a forging press. The huge titanium alloy blank is first expanded radially into an octagonal cross-section rod on the forging press, then uprooted, then drawn, and rolled into a round shape...

During this process, the internal grain structure grows rapidly in a predetermined direction.

"Report: The first few slices show that phase A is exhibiting a growth trend!"

"In the latest section, some of the α phase gradually dissolved into the β matrix, forming lamellar tissue!"

"During the final annealing, the temperature was close to the phase transformation temperature. The β matrix underwent a redistribution of alloying elements, and the lamellar structure disappeared!"
