Iron has been produced, and it really has produced iron. After nearly an hour of smelting, the iron ore is melted by the high temperature of coke. Some of the impurities and lime are merged into a calcium component, and the other part of the pure iron becomes molten iron, mixed with the slag and slowly flows to the iron outlet below.

At this time, after manual separation, the slag floating on the molten iron was thrown out from another hole, and the remaining pure molten iron was released from the open iron outlet.

This is the first time that Blacksmith Zhong has seen so much iron. It is estimated that it should be about a thousand kilograms after cooling, which means that this small blast furnace can produce thousand kilograms of iron every two hours.

What is this concept? Not to mention whether steel is made or not, even if it is burned, it will be at least 5,000 kilograms in a day, and 1.5 million kilograms in a year.

One million and a half kilograms, how much pig iron production in the Tang Dynasty is in a year? It’s about one million?

Words like excitement are no longer enough to express the emotions of the young people near the small blast furnace at this time. If it weren't for the existence of rationality, I guess someone might jump into the stove and sacrifice themselves to the sky if they are not good.

Li Yuan and Yu Zhining were stunned when they heard the cheers of everyone, and then sent Chen Huo to see the situation. As a result, that guy Chen Huo was gone forever. After that, he also joined a hysterical carnival. After a while, it seemed that he remembered his mission and ran back.

"The Supreme Emperor, Lord Yu, I'm going to have iron, I'm afraid there are not as many as a thousand pounds." Chen Huo's face was full of excitement, and a sentence was almost shouted out. If it weren't for the people who were smelting iron there, I'm afraid that Li Yuan's mysterious identity would have to be exposed.

However, who can still care about these things now? The concept of "a thousand jin" in two hours has scared Li Yuan and Yu Zhining. These two old guys are not the idiot Zhong Blacksmith.

They knew that this was just the output of a small blast furnace at the moment. If nine such blast furnaces were built, the steel output would immediately increase tenfold.

This, this is simply a miracle!

Although Yu Zhining was born in a gentry, he looked down on those craftsmen and felt that Li Muyun personally participated in the lowly work of iron smelting, which was a bit of a loss of face. But after hearing the number of iron smelting, this half-big old man had already thrown this discrimination to Jiuxiaoyun, with shock in his eyes.

...

Beside the small blast furnace, before everyone's excitement had passed, Li Muyun had already come to his senses and kicked the fat man and Wang Jie one by one: "What are you doing while standing there? You haven't continued to add fuel to the stove. The temperature drops in a while, and the stove will be useless!"

"It's useless? Why?" Wang Jie, who had made a furnace of iron with his own hands, did not realize the problem after the furnace temperature was cooled, and scratched the back of his head and asked.

"Don't worry about why, just add the material quickly to keep the stove at the current temperature and don't lower it. Let's talk about other things when you go back tonight." Li Muyun did not explain anything to Wang Jie, but just urged him to get faster, and the fat man on the side had already run to the side to greet people.

"Mu Yun, this is wrong. You'd better control the yield. If you continue to refine this way, you'll be afraid that you'll use up all the ores in less than three days." Fang Yizhi is currently acting as a think tank. After the excitement just now, he regained his rationality and quickly realized the key to the problem. He pulled Li Muyun away from the noisy crowd and pointed to the ore pile in the distance and said.

"Let's do this for the first few furnaces. Everyone is very happy. Let them be excited. After burning two furnaces, reduce the output by half." Li Muyun obviously realized this problem under Fang Yizhi's reminder. He rubbed his chin and looked at Wang Jie and the fat man who were directing workers to continuously load the feeding mouth of the small blast furnace.

"Half is not enough, it must be reduced by half." Fang Yi shook his head: "We have saved these raw ores for nearly half a month. You will use up all of them in six or seven days. What should we do next?"

"Let's do it first, send someone to the city to urge it to see if Lao Wang can increase the transportation volume." Li Muyun said smacking his lips.

"I don't think it's possible. Not to mention whether the mine can mine so many raw ores, even if they can be mined, the cost will increase relatively after the transportation volume increases. The Wang family is not a fool, so they shouldn't do such stupid things."

Li Muyun shook his head: "It's just a raw ore of 500,000 kilograms of iron, and it's two million kilograms. With this limit, the total freight is the same, and it has nothing to do with how many ores are transported every day. This matter is settled. I'll let Wang Jie go to the city again."

Fang Yizhi was not proficient in mathematics, but he still understood the principles. After listening to Li Muyun's explanation, he nodded and said, "Okay, then you can do it. Anyway, you pay attention to the stock."

...

After finalizing the matter of communicating with the Wang family to increase ore transportation, Li Muyun wandered around in vain. Soon after, he ran to the riverside, came to the two old men, and joked, "You two are really leisurely, and you don't go to take a look."

"I'm not a fool, are you afraid of being hot and unable to kill me?" Li Yuan rolled his eyes and said angrily.

"Hehe..." Li Muyun smiled awkwardly and squatted to Old Li Yuan regardless of his image: "Actually, you should really go over and take a look. The iron was quite spectacular when it flowed out."

"It's boring if you don't look!" Old Li Yuan continued to shake his head, but the old man looked at Li Muyun with a strange look, making people feel that the old man was just watching a joke.

In the end, Yu Zhining was quite realistic. He glared at Li Muyun, who was very unseen, and then said, "Muyun, I saw that you just discovered a problem with iron smelting, but I don't know if you found it!"

"What's the problem?" Li Muyun asked in confusion.

"Didn't you make all the iron refined into a whole piece?"

"And! Yes!" Li Muyun nodded.

"It's true!" Yu Zhining sighed, looked at the old Li Yuan who was in a scammer, then looked at Li Muyun again, and then said slowly for a while: "Have you ever considered how to forge such a large piece of iron next time?"

How to forge it next time? Isn't it just..., damn, it seems like I've really cheated myself.

You know, the Tang Dynasty did not have as many cutting methods as in later generations. Wherever there was a large pile of iron worth more than a thousand kilograms, even if Li Shimin came, he would probably not be able to get a small piece from it.
