After nearly an hour of smelting, the iron ore is melted by the high temperature of the coke, and some of the impurities are fused with lime to become a calcareous component, and the other part of the pure iron becomes molten iron, mixed with slag and slowly flows to the tap hole below.
At this time, after manual separation, the slag floating on the molten iron is thrown out from the other opening, and the remaining pure molten iron is released from the open taphole.
This is the first time that the blacksmith has seen so much molten iron, and it is roughly estimated that it should be no less than a thousand catties after cooling, which means that this small blast furnace can produce a thousand catties of iron every two hours.
What is this concept, not to mention that there is no hundred steelmaking, even if it is burned out of pig iron, then there are 5,000 catties in a day, and 1.5 million catties in a year.
One and a half million catties, Datang's annual pig iron output is only about one million Words like excitement are no longer enough to express the emotions of these young people near the small blast furnace at this time, if it weren't for the existence of reason, it is estimated that someone might jump into the furnace and sacrifice themselves to the sky.
Li Yuan and Yu Zhining were stunned for a moment when they heard everyone's cheers, and then sent Chen Huo over to see the situation, but Chen Huo's guy was gone, and after the past, he also joined the hysterical carnival, and it seemed that he remembered his task for a long time, spread his legs and ran back.
"Emperor Taishang, Lord Yu, the iron is out, I'm afraid the number is not as much as a thousand catties."
Chen Huo's face was full of overexcited expression, and a sentence was almost shouted, if it wasn't too far away from the people who were smelting iron over there, he would have to expose Li Yuan's mysterious identity.
However, who can take care of these now, the concept of two hours of iron has already scared Li Yuan and Yu Zhining, these two old guys are not the idiots of Blacksmith Zhong.
They know that at the moment this is the output of only a small blast furnace, and if nine more such blast furnaces are built, then the steel production will immediately multiply tenfold.
This, this is simply a miracle Although Yu Zhining was from a scholar family, he looked down on those craftsmen a little, and felt that Li Muyun's personal participation in the lowly work of ironmaking had lost his face.
But this half-old man, after hearing the amount of iron, had already thrown this discrimination out of the clouds, and his eyes were shocked or shocked.
On the edge of the small blast furnace, everyone's excitement had not passed, Li Muyun had already come back to his senses, and kicked the fat man and Wang Jie: "What are you still doing in a daze, don't continue to add ingredients to the furnace, the temperature will drop down after a while, and the furnace will be wasted."
"Why is it wasted" Wang Jie, who had made a furnace of molten iron with his own hands, did not realize the problem after the furnace temperature cooled, and scratched the back of his head and asked.
"Regardless of why, just add the ingredients quickly, let the furnace keep the current temperature and not drop down, and wait until we get back in the evening."
Li Muyun didn't explain anything to Wang Jie, just urged him to hurry up, and the fat man on the side had already run to the side to greet people.
"Mu Yun, this situation is not right, you'd better control the output, if you continue refining like this, I'm afraid that it won't take you three days, and those ores will be used up by you."
Fang Yizhi is acting as a think tank at the moment, and after the excitement just now, he regained his senses and quickly realized the key to the problem, 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 get excited, and after two furnaces are burned, the output will be reduced by half."
Li Muyun was obviously aware of this problem under Fang Zhizhi's reminder, rubbed his chin and looked at Wang Jie and the fat man who were directing the workers to continuously load the feeding port of the small blast furnace and said.
"Half won't work, it must be reduced by half."
Fang Zhizhi shook his head: "We have stored these raw ores for nearly half a month, and you will use them up in six or seven days, what should we do next." ” "Let's do this first, send someone to Fucheng to urge, and see if the old king can increase the volume."
Li Muyun smacked his lips and said.
"I don't think it's possible, not to mention whether the mine can mine so much raw ore, even if it can be mined, the cost will increase relatively after the volume increases, and the Wang family is not a fool, so they shouldn't do such a stupid thing."
Li Muyun shook his head: "It's just 500,000 catties of raw ore for iron, two million catties of raw ore, with this limit, the total freight is the same, and it doesn't have much to do with how much ore is transported every day, this matter is so decided, I will let Wang Jie go to Fucheng again." ” Fang Yizhi is not proficient in arithmetic, but he still understands the reason, and after listening to Li Muyun's explanation, he nodded and said, "Okay, then you can look at it, anyway, you pay attention to the stock." ” After finalizing the matter of communicating with the Wang family to increase the amount of ore transported, Li Muyun stumbled around with nothing to do, and after a short time, he ran to the river, came to the two little old men, and said teasingly: "You two are really leisurely, and you don't go over to take a look." ” "The old man is not a fool, he can't kill himself if he is afraid of the heat," Li Yuan rolled his eyes and said angrily.
"Hehe" Li Muyun smiled awkwardly, and squatted beside Lao Li Yuan regardless of his image: "Actually, you should really go over and take a look, the molten iron is quite spectacular when it flows out." ” "Don't look at it, it's boring" Old Li Yuan continued to shake his head, but the old man's eyes were a little strange when he looked at Li Muyun, making people feel that this old man was just watching a joke.
In the end, Yu Zhining was more realistic, glared at Li Muyun, who was very unimaged, and then said: "Muyun, the old man saw that you just found a problem in iron smelting, I don't know if you found it."
"What's the problem," Li Muyun asked puzzled.
"Didn't you make all the iron you smelted into a single piece?"
"Ang, that's right," Li Muyun nodded.
"Sure enough" Yu Zhining sighed, glanced at the old Li Yuan in the midst of the schadenfreude, and then looked at Li Muyun, and then said slowly: "Have you ever considered how you will forge such a large piece of iron next time?"
How to forge next time, isn't it,, it seems that he really pit himself.
You must know that Datang does not have as many cutting methods as in later generations, and where is the big iron lump of more than 1,000 catties, even if Li Shimin comes, it is estimated that there is no way to get a small piece from it.
This is not an ordinary embarrassment, because even if he has the ability to forge more than a thousand catties of iron, but no one can make a weapon of more than a thousand catties, which means that this thing is a waste when it comes out, well, it is still a big waste
