Chapter 32 Knowing is easy to do

Everyone looked at each other, including Su Xin and Zhang Wanhe, were surprised outside.

After a long time, Hardware said, "It's that simple?"

No wonder they didn't believe that the German technology, which was so tall, was buried in iron ore for a few days.

Then, they naturally began to doubt the authenticity.

Zhang Ruozhong, director of the sand turning plant, said half-believingly: "If it weren't the case, they should have discovered it would have been wrong long ago! They wouldn't have been unable to build shells!"

Hardware said, "It's not that simple, there must be something wrong."

Zhang Wanhe frowned and asked Wang Xuexin: "Comrade Wang Xuexin, did I forget anything?"

Wang Xuexin continued to pretend to be confused: "Then I don't know."

Su Xin, who had been silent, suddenly thought of something: "He is so bright. Comrade Wang Xuexin said it may be correct, and Coke did that. Just Buluo is much more complicated and difficult than what they thought."

Then everyone was even more confused.

Wang Xuexin said in his heart that he was so powerful.

As the saying goes, "Asiders look at the tricks, while laymen watch the excitement." Wang Xuexin's information on the seemingly simple operation actually has many knowledge and difficulties.

Others didn't see it, but weren't seen by that little girl.

Zhang Wanhe asked in confusion: "Comrade Xiao Su, I will say it slowly. How could it be complicated and difficult to do it if you really want to do that?"

Su Xin explained:

"Manager, the reason why our red-mouthed pig iron is hard and brittle and lacks toughness is because it contains too high carbon."

"Since the carbon content is high, please precipitate the carbon in the iron."

"How to precipitate that carbon?"

"Buried red-mouthed pig iron in iron ore and heated, the iron ore will continuously release a small amount of oxygen during the heating process."

"Those oxygen react with the carbon in red-mouthed pig iron to produce carbon monoxide and carbon dioxide, which will reduce the carbon content to achieve the purpose of toughening!"

Others were confused when they heard this, even Zhang Wanhe was no exception.

Wang Xuexin nodded secretly. That girl did have two tricks, and she said it as if she saw the answer.

Su Xin sensitively noticed that Wang Xuexin had a good expression. They all looked confused, but he was relaxed and calm, as if he had known those things long ago.

Bu Lu thought about it again, and then felt the illusion of whether he was a karma.

That expression...is not sure if I can't understand it at all!

After a while, Zhang Wanhe asked again: "Comrade Su Xin, as I said that, is that method indeed feasible?"

Su Xin nodded: "Although he is very uncertain, it is probably feasible. Even if it doesn't work, it's OK to try it."

"Then... why do you say it is much more difficult and complicated than they imagined?" Zhang Wanhe didn't have an old leg, and he knew the more important thing about the cocoa that he asked for.

Su Xin explained:

“He thinks the focus of that technology is on temperature control.”

"They need a high enough temperature to make the carbon in red-mouthed pig iron react with oxygen."

"But if the temperature is too high, the red-mouthed pig iron and iron ore will all melt and mix together, which will lose the meaning of toughening."

“So, they need to find a suitable temperature and keep the temperature outside that range.”

"Is that one of the difficulties!"

After hearing those, everyone suddenly realized.

Without measuring instruments and equipment, we don’t even know the temperature, let alone control it.

Su Xin continued:

"In addition, there are many impurities in iron ore, and the melting points of those impurities are different. They are very cocoa and react with red-mouthed pig iron during the heating process, causing a series of problems."

"So, he speculated whether the iron ore used by the Japanese had been treated to remove impurities before being used to toughen them."

"Well, then, is there another difficulty."

What Su Xin said made Wang Xuexin want to find a system to refund the money, so it was exactly the same.

After Bulu said this, I asked for the information given by the system to remind me that Su Xin could not push out those things.

What's more, there are two very important questions. Su Xin: one does not have temperature and the other does not have impurities.

Those two questions seem simple, but they have to be done for a long time.

For example, if you don’t know which temperature is right, you need to test it at one degree or another. When will you test it?

Forget it, let's just shake it all out. Regardless of whether they will doubt it, it will be better than a year or two to try it!

Thinking of this, Wang Xuexin interrupted, "When Comrade Su Xin said that, he remembered that sometimes the Japanese ore was not in a hurry to clean up, so he simply buried the shells in the clean Shanxuan and burned them..."

"Shan Xuan!" Before Wang Xuexin finished speaking, Su Xin widened her eyes and nodded repeatedly: "You are wrong, Shan Xuan may be fine. Why didn't he expect it!"

"So it's really feasible?" Zhang Wanhe was a little unbelievable.

"Eighty percent feasible!" Su Xin explained: "Shanxuan mainly asks whether the ingredient is silicon dioxide. Its melting point is just higher than that of iron. Even if the iron burns, it will not melt. That is, there is no impurity that will be mixed into the red-mouthed pig iron. If the toughening effect is very good, it is not as good as the purified iron ore."

Everyone looked at him and he looked at me, but there was no sound.

After a while, Zhang Ruozhong said, "Then, there is only Dong Wen left."

Then he turned his attention to Wang Xuexin and asked, "Comrade Wang Xuexin, I don't happen to remember the temperature, right?"

"How is that!" Wang Xuexin laughed awkwardly: "He is just a rough man. He doesn't know what temperature is, but he knows that they are shouting numbers all day long..."

Everyone was so surprised that Dongba almost fell into Donglai.

"What number?" Su Xin asked.

"For example, one hundred, two hundred, two hundred, two hundred three..." Wang Xuexin said: "It's like selling pork, is that useful?"

"It's useful and useful!" Everyone came together and lighted their heads like pounding garlic.

Zhang Wanhe asked nervously: "Comrade Wang Xuexin, do you remember how many kilograms of pork they sold at most?"

"I can't remember it very clearly!" Wang Xuexin put on a embarrassed expression: "Anyway, I won't shout it every time I'll shout it to more than 900!"

"More than nine hundred!"

"Let me remember the East!"

"More than nine hundred, how much? Don't you deny that end?"

Wang Xuexin replied: "Why should there be no other end? I asked the Japanese to be more than 95 years old and started to feel nervous. I was thinking, would the pork pizza be sold?"

Su Xin couldn't help laughing out loud. She couldn't imagine the technicians in the Japanese Arsenal shouting and selling pork.

Others couldn't help laughing, but they didn't dare to be careless even though they smiled:

"Nine hundred and five!"

"Why should it be outside of nine hundred and fifty!"

"Let's try tomorrow..."

"What tomorrow!" Zhang Wan and Teng stood up with a "trial" sound: "Let's try now, Ma is making several shell shells for him... No, dozens of them are coming out, and they are burned in different batches!"

"No!" The directors of each branch responded, and Dangdong left like a fire.

Zhang Wanhe held Wang Xuexin's legs tightly and said with a feeling:

"Comrade Wang Xuexin, if you want to succeed, I will help you!

"Do I know how difficult the iron problem brings us?"

"We guerrillas have to work hard to cut the rails, so whether we can produce qualified steel by ourselves."

"Then...that's really good!"

Speaking of this, even Zhang Wanhe couldn't think of the words.
