Regarding the follow-up matters of Experimental Class's enrollment, Senju Chen has nothing to do with it. The teacher has made arrangements, the teaching materials are complete, and the seeds called "science" have been planted, and they are just waiting for the future to bear fruit.
Today, Senju Chen led Tatekura Clan, a group of about a hundred people, large and small, to the newly built forging factory in the west of the village.
Tatekura Gento lost to Senju Chen in public before. Although this old man has conservative ideas, his character is still good. At least he accepted the bet and accepted defeat, but he still looks unconvinced.
Senju Chen led everyone to the door of the forging factory, looked at the sign [Konoha Industrial Federation·First Forging Factory] at the door, turned to Tatekura Gento and smiled.
"Let's go, Gento clan leader."
Tatekura Gento looked at the sign [Konoha Industrial Federation·First Forging Factory] in front of him, then looked at the slightly confused tribesmen behind him, and took a deep breath.
"Come in."
After hearing the clan leader's words, the thirty-seven members of the Zhencang clan, plus the craftsmen from a dozen ninja shops and seal houses, a total of one hundred and twenty-six people, walked in one by one with their heads lowered.
That expression is like that of a death row prisoner rushing to the execution ground!
After entering the factory gate, everyone saw three things that they had never seen before standing in the center of the factory. They were not furnaces. At least they didn't look like furnaces. They were made of iron ash and were half a man and a half tall. There were pipes as thick as an arm coiled on top. The pipes were connected to the ground. The ground was paved with neat black stone slabs. There was a row of small glass windows on the furnace belly, and a faint red light shone in the windows.
"What... what is this?" An old craftsman's throat was dry.
"This is an arc induction furnace."
The voice came from the side. A young man in a white coat and glasses walked over with a stack of paper and a sign on his chest: Public Security Department Technical Group·Hiraga. He looked to be less than twenty-five years old.
"Mr. Minister." Hiraga saluted Senju Chen.
"Yeah." Senju Chen first nodded to Hiraga, then turned to introduce to everyone.
"This is the engineer from our Industrial Federation - Hiraga. He will also be your future mentor. He will tell you how to use these tools, including improving the production process, etc."
"Hello, masters, I am the instructor who will be responsible for giving lectures to you from now on." Hiraga
"Lecture." Gento chewed these two words in his mouth, "I have been working in iron for thirty-six years, you give me a lecture?"
Hiraga pushed up his glasses and said without any worries, "Yes. It will last for three months."
He divided the paper. Each piece of paper was densely drawn with lines and numbers.
[Alloy Steel-01 Type Smelting Process Regulations (Seventh Revision)]
Main ingredient: low phosphorus pig iron 82.5%
Excipients: Chromium 12.1% / Nickel 3.2% / Tungsten 1.4% / Carbon 0.8%
Melting temperature: 1,560 degrees, allowed to fluctuate by plus or minus 15 degrees
Keep warm: forty minutes
Forging: hammering starts when the temperature drops to 1,100 degrees, and stops when the temperature drops below 850 degrees.
Quenching medium: mineral oil, oil temperature 60 degrees
Tempering: 520 degrees, two hours
There was dead silence in the workshop.
"One thousand five hundred and sixty degrees? What do you mean?" the owner of a talisman house muttered, "How many degrees is one degree?"
"When the charcoal fire is burnt white, it will be about one thousand three hundred." Hiraga replied, "If it is two hundred higher, your old furnace will collapse on its own."
"That chromium, nickel, tungsten..." Another old craftsman held up the paper, his hands shaking, "I have been working on these three things for forty years, and I have never heard of any of them."
"Normal." Hiraga said, "These three are found in Land of Fire's mine. No one knew what they were before, so they were all thrown away as waste."
"What does this twelve o'clock mean?" Gento suddenly spoke.
"These values are the most appropriate ratios concluded after extensive experiments."
"Then why not twelve? Why not thirteen?"
Hiraga opened the booklet in his hand and turned to a page with pictures of dense dots.
"At eleven point five, the iron plate can't stop Great Fireball. It can block it at thirteen, but it will break with a hammer. Twelve point one is the best point that Mr. Scorpion has tried out after 317 experiments."
"Three hundred and seventeen times?" Gento repeated.
He has been making iron for thirty-six years. In thirty-six years, he has scrapped a total of forty furnaces. Forty furnaces are enough to make him feel distressed for half a lifetime.
That guy named Scorpion, he wasted 317 furnaces just for a board???
Gento balled up the paper, stuffed it into his arms, turned around and left.
For the first seven days, no one touched the stove.
Hiraga Let them learn from the most basic things. What is temperature, how to read it with a pyrometer, why steel has different colors at different temperatures, and why the direction of hammering changes the invisible "grain" inside.
On the third day, the two old craftsmen couldn't bear it anymore, threw their books and left.
On the fifth day, five more people left.
On the eighth day, Hiraga started the first furnace. The alloy materials were put in according to the proportion, and as soon as the furnace door was closed, the red light in the small glass window turned to dazzling white. Forty minutes later, the material was discharged, and the red steel billet was clamped to the forging table by the mechanical arm.
"Masters, from now on, the forging work will be left to you." Hiraga said, "If the machine cannot do this step well, you have to rely on your hands."
Everyone's waist suddenly straightened a little.
Yes, Hammer. This is their territory.
Gento was the first to take the stage.
He took off his shirt, revealing old scars on his back and tendons all over, and grabbed his family's eight-pound hammer - the head of the hammer was worn by him until it was just a round and blunt head. There were five notches on the handle, left by his grandfather, his father, and himself.
"Watch," he said.
When the first hammer was struck, sparks flew everywhere.
That sound is wrong.
It wasn't the "click" he was familiar with, but a muffled sound, like hitting wet sand. The feel of the hammer tip when it bounced was also wrong - it was too soft, and the steel was flowing to both sides instead of sinking.
"The temperature is too high." Hiraga said below, "Now it is one thousand three hundred and four, and the regulations say it is one thousand one hundred to start the hammer."
"When I strike, I look at the color, not your stuff." Gento yelled back, "If you don't hit the color, you won't be able to hit it when it gets cold!"
He hit eighty-seven times in a row.
The shape of what came out looked okay. Hiraga took a handheld instrument and put it on it, and the screen jumped twice.
"There are Six Paths cracks inside, all on the central axis." He turned the screen over, "This one is scrapped."
In the second furnace, Gento changed his mind and waited for the steel to cool down a little before hammering. When it was cool enough that he felt it was time to lift the hammer, the instrument read 920.
Fifty degrees below the stop line.
After forty hammer blows, a piece of the edge of the billet broke off and flew out, leaving a hole in the wall.
"Steel has already begun to harden at this temperature." Hiraga said, "To hit it again, just use a hammer to hit the glass."
The third furnace.
Gento stood in front of the forging table without saying a word, staring at the red piece of steel without moving.
One minute. Two minutes. Three minutes.
He was waiting for the "feeling" he had accumulated over the past thirty-six years to come back. That feeling had never fooled him. When he was seventeen, he relied on this feeling to play the best Kunai in the family overnight.
The steel changes from white to yellow, from yellow to orange, and from orange to dark red.
"Clan leader." Someone behind him whispered, "It's cold..."
Gento Lift the hammer and drop it.
"Click."
The billet is broken into two pieces in the middle.
