There is no steel in this era!

Feng Linshan used a blast furnace to make iron, and the impurities contained in this iron were already less than all the iron on the market, so the red-coated cannon cast by it solved the problem of exploding.

But it is not yet up to the requirements for steel.

Fu Xiaoguan didn't care about this matter originally, anyway, Feng Linshan's iron was already the best, and he didn't plan to spend any more time and energy to tinker into steel.

But just now he heard the crisp sound of the blacksmith forging this week, and then saw the hoe in his hand, and realized the importance of steel.

The so-called pig iron rinsing technology is to mix carbon and molten iron in proportion to pour on the cutting edge, and then repeatedly hammer, the finished cutting edge will be sharper and tougher.

So if you can get 100 steels out, this is definitely an epoch-making thing!

The military reversal of the Han Dynasty against the Xiongnu in the previous life, on the one hand, Ma Liang smoothed out the gap in speed, and on the other hand, there was an extremely important aspect, the weapons of the Han Dynasty were much ahead of the Xiongnu.

And the weapons of the Han Dynasty were made of steel, and it was the technology of frying steel!

The two most important aspects of steelmaking are temperature, even if there is a blast furnace, but because the blast furnace is not advanced, the furnace temperature cannot reach more than 1600 degrees, so the best way is to fry steel.

The frying of steel involves the control of carbon content, which requires the use of carburizing into steel.

And Blacksmith Zhou is the only craftsman Fu Xiaoguan has seen so far who knows how to carburize into steel, this is simply an amazing talent!

So Fu Xiaoguan gave Blacksmith Zhou this problem, thinking that if he could solve this problem, then he would have to get this person into his hands anyway.

Blacksmith Zhou is also very entangled at the moment, he has studied this craft handed down by his ancestors for more than 20 years, and he can be said to have mastered the pig iron pouring technology.

But the entire sword must be cast into steel...... He has been trying since his early years, but so far he has not succeeded.

No matter how you get it, the impurity content in the iron will exceed the standard, resulting in the final product not reaching the hardness of steel.

This boy is obviously knowledgeable, and it is definitely not possible to fool him, but this silver must be earned by himself......

"Don't hide it from the child, I really need silver to save my life, but the villain has not yet mastered the method of turning the whole piece of steel, can you give the villain a little time?"

Fu Xiaoguan thought for a while, "Do you have any paper?" ”

“…… Is it feasible to have yellow paper? ”

"Okay, take two pieces of yellow paper, and I'll tell you."

"Can you read?"

"Yes."

"That's better."

Blacksmith Zhou was shocked again, could it be that this young man had already mastered the method of steelmaking?

He couldn't believe it!

Because there is only iron and no steel in this world, and even his own pig iron drenching technology is unique in the world, if it were not for the ancestral training that he could not leave Pingling, he would have taken his family to the big city to make a living.

He brought yellow paper, and Fu Xiaoguan took a piece of charcoal, and wrote and drew on this yellow paper.

This is the easiest way to fry steel.

Fu Xiaoguan drew a wok, and explained to Blacksmith Zhou: "This thing is a frying steel furnace, the structure is simple, digging into a pot-shaped furnace, the inner wall is coated with refractory mud, the charge is lit first during operation, and after the fire is strong, crushed pig iron is added, the furnace door is blocked, and the air is blown from the furnace mouth ......"

He wrote as he spoke, writing three pages freely, unconsciously explaining for an hour, not paying attention to Blacksmith Zhou's shocked expression, and not knowing that Zhang Pei'er, who was hiding on the roof and eavesdropping, had already covered his mouth-

"How does he know so much?"

"Isn't he the most talented man of letters in the world?"

"He was able to talk to a blacksmith about what kind of steel to make!"

Zhang Pei'er's heart was extremely shocked, and then she understood why no one had been able to create the things that Fu Xiaoguan was making in Xishan.

And the method of frying steel he said is only afraid that it will change the entire smelting industry!

Blacksmith Zhou's shock came from Fu Xiaoguan's profession, and the doubts he had stored in his mind before were easily solved under Fu Xiaoguan's detailed explanation, but he deeply knew that this was not light, at least the young man in front of him must have gone through countless experiments before he could master this top technology!

It's just that...... Blacksmith Zhou began to doubt himself, why did this young man pass on such a top-notch technique to me?

Even if his ancestral pig iron pouring technique also has group training, not only can it not be passed on to outsiders, even if it is his own daughter!

It can only be passed on to a son, and if there is no son, the craft will be extinct.

And the reason why Fu Xiaoguan handed over this steel frying technology to Blacksmith Zhou was because he only knew a little about it.

He didn't know how to carburize and what the proportion should be, but this technique was only known to Blacksmith Zhou.

He wasn't worried about Blacksmith Zhou playing with him, and with his current status, there was no difference between strangling a Blacksmith Zhou and strangling an ant.

"Do you understand it now?" Fu Xiaoguan put down the charcoal pen and asked.

The villain understood, and Childe's explanation made the villain suddenly! Just ......"

Blacksmith Zhou paused and asked the doubts in his heart, "Gongzi granted me this law, I don't know what conditions Gongzi has?" ”

"It's very simple, I have an iron mine in Linjiang, and the iron I calcined is also very good. Go to my ironwork bureau and give you thirty taels of silver a month, and you will be responsible for making steel for me!" ”

Blacksmith Zhou was taken aback again, the salary of thirty taels of silver! This naturally made him excited, but ......

He sighed and said, "Childe, can you say another condition?" ”

Fu Xiaoguan frowned, "What difficulties do you have?" ”

"It's not my own difficulties, but my ancestors have trained me, if my generation inherits this smelting technique, they can't leave Pingling."

"What's the reasoning?"

Blacksmith Zhou was silent for dozens of breaths, and said in a low voice: "The ancestor was originally a blacksmith of the imperial court, and he was ordered to come here in the previous dynasty to go to the Pingling Mountains to find gold mines...... Then I stayed in Pingling, and now my generation is the eighth generation, and the training is passed down from the ancestors to the present. ”

Fu Xiaoguan's heart moved, "Have you found it?" ”

Blacksmith Zhou shook his head, "It is not recorded in the ancestral hometown, but in the early years of the Yu Dynasty, people were also sent to the Pingling Mountains to look for it, and it is said that no gold mine was found, but an iron mine was found, but the mineral deposit was not large, so it was not mined." ”

"Do you know how to view mountains?"

"It's also an ancestral heirloom."

"Have you been to Pingling Mountain to see it?"

"I went in once with Sun Er three years ago and took a look."

"Do you think there's value in mining?"

"That vein is very complicated, buried very deep, I only found a few iron caps, if you want to explore carefully, you have to pluck out the landslide, if you can find more iron caps, you can confirm its value."

Fu Xiaoguan pondered for a moment, "This steelmaking method is only known to you, don't spread it!" You experiment first, take these silver tickets first, and I'll come back to you in a few days! ”

"Childe's surname?"

"Fu Xiaoguan!"
