Chapter 920 A cunning rabbit has three burrows? I'll release the tiger back into the mountains!
LD furnace and CC technology.
(⊙o⊙)...
A friend said this is an alchemy furnace...
That's not wrong, but this thing is more powerful than an alchemy furnace.
Why do you say that?
Let's do a simple calculation. Take the famous alchemy furnace of Laozi, the one used to refine the stone monkey, for example. Even with the Samadhi True Fire, it would only reach a maximum temperature of 1200 degrees Celsius.
Why?
Because it couldn't train the stone monkey!
Stone monkeys, stone monkeys, aren't their main component just silicon dioxide?
Silicon dioxide has a melting point of 1,730 degrees Celsius, so Laozi's alchemy furnace couldn't melt it! Not only could it not be melted, but it also gave the monkey fiery eyes.
why?
High temperature removes impurities, silicon dioxide turns into glass...
However, the LD furnace is different. By blowing pure oxygen into the top, it reacts violently with elements such as carbon, silicon, and manganese in the molten iron, instantly generating local high temperatures of up to 2,300 to 2,500 degrees Celsius inside the furnace!
It is sufficient to easily melt various ore impurities, enabling efficient steelmaking.
In terms of temperature, it has an overwhelming advantage.
Temperature alone is not enough; the power of LD furnaces lies in three dimensions.
One is efficiency. Laozi (the legendary Chinese emperor) would spend 49 days refining a single batch of elixir. A 30-ton LD converter, from the moment the molten iron is fed in to the moment the molten steel is tapped, only takes about 45 minutes!
Furthermore, this furnace can precisely control the amount and time of oxygen blowing, as well as the slag-forming materials added. It can precisely control the composition and temperature of molten steel, just like formulating an equation, to produce steel of different grades and for different purposes.
Hmm? You mean there's one more dimension missing?
That's written there, right? One furnace produces 30 tons, and the entire tapping process takes only 30 minutes...
Now you understand, right? This LD furnace is actually the oxygen top-blown converter that has been written about by countless people!
However, simply producing high-quality molten steel is far from enough. This leads to the next revolutionary process that is a perfect match for the LD furnace—continuous casting (CC).
If the LD furnace is a "high-efficiency alchemy furnace," then the CC continuous casting machine is a "seamless alchemy platform." Traditional steelmaking is a three-stage process of "steelmaking - ingot casting - billet making." After the molten steel is cast into ingots, it needs to be cooled, heated, and then rolled. This process is not only time-consuming and labor-intensive, but the steel yield is also less than 85%.
However, after the LD furnace taps out steel, the molten steel flows directly into the arc-shaped crystallizer of the CC continuous casting machine, and can be continuously rolled into square billets and slabs within 20 minutes, increasing the yield to over 95% and reducing defects such as billet cracks and segregation.
The LD+CC combination in the photo is like installing a "dual engine" in steel production, representing not only a leap in efficiency but also a revolution in quality.
Having figured this out, Jiang Xia looked at the core parameter drawings of the CC continuous casting machine in front of him and could hardly believe his eyes!
"Hahaha! Junichiro, Junichiro! You're really my money-spending angel!" Jiang Xia couldn't help but slap the table and laugh. The complete core data for the LD+CC short-process technology was just 'delivered' into our hands like that?
"Hey, Old Wang, do you remember my first business deal? Hahaha, this Junichiro, hey, help me deliver a bowl of longevity noodles to him later!"
"I sincerely hope that this kind person lives to be a hundred years old!"
Jiang Xia turned around and took the noodles from Lao Wang's hand. He drank them in a daze, but did not forget to ask Lao Wang to treat Junichiro better.
But after the laughter subsided, a huge question immediately welled up in Jiang Xia's mind: "Wait a minute, it's like a boss dropped a huge loot drop during a raid. Why is that old guy carrying such core technical information with him?"
Even if technology needs to be transferred, more covert channels should be used.
Zhao Gang shook the chemicals off his hands and clipped the last photo onto the hanging rope in the darkroom: "This is the last one! Little Jiang, do you think we're missing anything? If not, Old Wang and I will catch them and take them to play on the Qin King's Single-Plank Bridge!"
"It's pretty comprehensive. I doubt even the technology transfer from Bao... later on would be this complete," Jiang Xia replied vaguely.
"But what on earth is this 'Qin King's Single-Plank Bridge'?"
"Hahaha... Let me tell you..." Zhao Gang took the chopsticks Jiang Xia handed him, and without any hesitation, stuffed a piece of noodles into his mouth. He immediately began to excitedly recount to Jiang Xia the scene of him and Lao Wang messing with Junichiro.
Jiang Xia held the bowl, looking at the words on the photo, trying to decipher their meaning.
"Analysis of ブラジル ミナスジェライスzhou 鉱石サンプル"
“This ‘ore’ definitely means mineral, and I recognize ‘analysis’… but what kind of mineral is this long string of ‘Brajiru Minas…’?” Jiang Xia was scratching his head as he read this section, which contained almost no Chinese characters. “Never mind, let’s keep reading!”
His gaze shifted to the next line:
"Adjust the value when using high-grade, low-phosphorus phosphorus produced by Furaru"
“Brajiru…” Jiang Xia subconsciously followed the shape of the characters and silently recited them. The shape of these characters, especially the first and last characters, gave him a vague sense of familiarity.
"Is this describing a type of ore?"
"Low-phosphate ore? Australia? That can't be... Those kangaroos hate Japan to the core right now, there's no way they could get high-quality ore from there..."
Yes, that's right!
At this time, Australia had absolutely no chance of providing the US with the high-quality iron ore that its steel industry desperately needed.
Rewinding to World War II, the Japanese military launched numerous air raids on Australia, the most famous of which was the massive bombing of Darwin, the largest attack on Australian territory by a foreign military in history.
To this day, Darwin still retains the bullet-scarred monument, and a memorial ceremony is held every year.
What makes it even more unbearable for Australians is the bloody history of the "Death Railway." Half of the 1.3 Australian prisoners of war were killed by the Japanese, and those compatriots who died of exhaustion and starvation on the tracks have become an eternal pain in the hearts of Australians.
After the S2 victory, Australia did not let Japan off easy. In the trial of Japanese prisoners of war, Australia broke with international practice and sentenced Class B and Class C war criminals to death as well.
Moreover, many prisoners of war disappeared after being taken in by Australian soldiers, with reasons such as dying from illness or accidental suicide...
So, in this matter, the kid with the dazed look has a lot of respect for the people of Australia; they really know how to seize any opportunity to take revenge...
His thoughts drifted a little far away, so far that Zhao Gang had already finished eating his noodles and was taking the bowl from Jiang Xia's hand when he startled the silly boy.
Suddenly, a scene completely unrelated to the steel technology before him sprang from the depths of his memory as a "person from the future".
That was a television broadcast of a World Cup football match co-hosted by Japan and South Korea in another time and space!
In the footage, a Brazilian star dribbles past an opponent, while countless fans in the stands wave yellow and green flags. The camera zooms in on a huge Japanese banner with slogans clearly written in Japanese to cheer for the Brazilian team, including the word "ブラジル" (Burajiru), accompanied by the commentator's enthusiastic shout of "Burajiru!"
“Brazil” — This is 'Brazil'!
Brazil! It's Brazil!
Having figured this out, Jiang Xia suddenly felt enlightened!
Yes!
The restless Japanese have been systematically emigrating to the sparsely populated and resource-rich football nation since the Meiji Restoration.
This trend continued even after World War II. Large numbers of Japanese immigrants purchased land in the football-loving nation, gradually infiltrating the agricultural, commercial, and even mining sectors.
Junichiro's family was clearly one of the most strategically astute members of this wave. Not content with simple agricultural cultivation, they leveraged their capital and technological background to invest in mineral exploration and establish primary metal smelting operations in the football nation early on.
Their true ambition is to combine the most advanced domestic steelmaking technology, LD converter, with the forming technology, CC continuous casting, with the country's abundant and high-quality iron ore resources, to establish a relatively independent "industrial enclave" or "technology backup base" overseas, less affected by domestic conglomerates and the international situation!
"That's really high-stakes stuff!"
The little guy with the tuft of hair muttered to himself.
"I'm not as good as him..."
"Huh? What's wrong?" It was rare to hear the silly kid say something so modest, so Old Wang picked at his ear and leaned closer.
"nothing……"
"Brother Wang, what do you think about us releasing Junichiro?"
