Working Prophet.

Chapter 654 Bessemer Steelmaking Method
With the first piece of iron ore in the green field being mined, the construction of a steel plant was logically put on the agenda.

Smelting iron ore into usable steel is not an easy task.

In another cosmic plane, humans began to use natural metals in the Stone Age.

However, copper smelting was not learned until about 5000 BC, and it is said that the ancient Romans were already using iron nails.

But until the twentieth century, before metallurgical science made great progress, it was basically luck to make a good piece of steel.

Taking Bratis Continent as an example, dwarves are usually considered to master the mysteries of forging, but even those dwarves who are known as masters actually have very limited production capacity.

Just like the Japanese swordsmiths in the past, there may only be a few works throughout the year.

It's not that they don't want to make more, after all, no one has trouble with money. The reason is that there are too many uncontrollable factors in the whole forging process.

Experience does help, but not always.

The good news is that Li Yu is here, and there is no need to wait hundreds of years for mass production of qualified steel.

An engineer named Bessemer had already written down the standard answer.

——By fully contacting the molten iron with the air, the oxygen and the carbon in it react chemically to form carbon dioxide, thereby taking away all the carbon in the iron, and then adding carbon in proportion after finishing the work.

The advantage of doing this is that the carbon content of the iron ore itself can be completely ignored, and any ore of any quality can be smelted into steel by this method.

Bessemer later opened his own steel factory and made a lot of money.

Li Yu remembered that during the period of great iron and steel smelting, local methods of steel smelting were vigorously promoted by the people in various places, and the same principle was used.

It can be seen that if there are no strict requirements on the quality of steel, steelmaking does not require any high-end equipment, and with the current level of productivity of Bratis, it is completely possible to do it.

In this way, Greenfield should be able to realize the freedom of armor and weapons soon, and it can even be sold domestically and re-exported in the future.

Of course, this is all for later.At present, the most important thing is to build the blast furnace first. At the beginning, Li Yu planned to hand over this task to Ge Lipeng.

Because Ge Lipeng, as a craftsman, is no stranger to the Bessemer steelmaking method, but during this period of time, apart from learning the language, Ge Lipeng is also busy imitating the Iowa rifling machine, which is used to cut gun barrels. rifled.

Before that, he had produced a musket according to Li Yu's request, and helped Miss Rabbit win the championship in the martial arts tournament.

But Ge Lipeng was not satisfied, especially after seeing the terrifying flying ability of those Yi people, without Li Yu's reminder, he had already started to improve those flintlock guns.

What he is doing now is to engrave rifling inside the barrel to further improve the muzzle kinetic energy and shooting accuracy.

But Ge Lipeng recommended another person to Li Yu.

"He Chaoyang?" Li Yu thought for a while, then shook his head and said, "He can't, he was hurt too deeply by civil engineering. Before reincarnation, I promised him that I would not force him to do civil engineering again."

"The past is the past, and the present is the present. I think Mr. Prophet, if you go to him now, he will not refuse."

Li Yu was a little surprised by Ge Lipeng's words.

"Really? Do you know where he is now?"

"He should be in the small village south of the iron tower, where a windmill is being built recently, and he passed after hearing the news."

Li Yu wondered if there was something wrong with his ears. Someone's resounding sentence "Dogs can't learn civil engineering" is still in his ears.

But no matter what, the prophet of Shuangxiu Sect found He Chaoyang according to the direction Ge Lipeng pointed out.

From a distance, Li Yu saw He Chaoyang with an iron pot on his head, hands behind his back on the ridge of the field, inspecting the half-built windmill.

When he got close, he could still hear him speaking a crappy common language, jumping out word by word, and he was afraid that the nearby craftsmen would not understand, and then he squatted down on the ground and began to draw. .

When Li Yu walked over, he was talking excitedly, "This... the structure is so boring, do you understand?"

After listening for a while, Li Yu couldn't bear to listen anymore, so he said to He Chaoyang, "Tell me first, and I will translate for you."

When He Chaoyang heard the voice behind him, he turned his head abruptly, and found that it was Li Yu who came, and couldn't help being a little embarrassed.

The branches that were halfway through the drawing just stopped there.

"Prophet Merlin, you, why are you here?"

"I'm here to find you."

"Looking for me?" He Zhaoyang's face was flushed red, as if he had been caught having an affair and was raped in bed, his back was completely soaked in a short while.

"You finish the matter at hand first, and we will talk later."

He Chaoyang nodded. With Li Yu's help, he explained the problem clearly in a few simple sentences.

Under the admiring eyes of all the craftsmen, the two walked back.

Li Yu said, "I thought you hated civil engineering."

"Well..." He Zhaoyang stammered, "I used to hate it, but now I don't hate it anymore."

"why?"

"Because I seem to have found the pure joy of building again, just like playing Lego when I was a child, and I can also help others, so I still... have a sense of accomplishment."

He Zhaoyang finally spoke out what was in his heart, and finally said with emotion, "I just realized that what I hate is not this job, but the industry environment at that time.

"Working overtime has become a habit, desperately kneeling and licking Party A, blindly pursuing speed, and constantly reducing costs... But what am I, even if I hate it, it's useless." He Zhaoyang laughed at himself.

However, a smile appeared on his face soon, "Fortunately, it's different here, um. I feel like I've fallen in love with civil engineering again."

"Very good. I was still thinking about what to do for you in the future. Although you said that you can do anything except civil engineering, it is always better to be able to do a job you like than to just find a job for a living. Work better." Li Yu said.

"It just so happens that I have a job here to trouble you. It stands to reason that after coming here, you will go to a language school for three months before you officially start working.

"But the situation in various places has become turbulent recently, and I have to prepare in advance. I can only let you work while studying, but don't worry, there will be no shortage of rest time anyway, and the normal wages will be paid at work. and bonuses."

He Chaoyang scratched his head, "Actually, I've already found a part-time job as a construction consultant for Ms. Ilea... We met in the new city before. The main reason is that I am also a little tempted and want to wander around the construction site.

"So I think I'm ready to work. If you have any big tasks, you can entrust them to me. I will definitely complete them with quality and quantity."
