Tiantang Splendid

Chapter 496: What Li Taizhi Sees

The hot air balloon sounds high-end, but the principle is very simple. The density of hot air is lower than that of cold air, so the air in the air bag can be heated and it can fly into the sky. Li Tai is not interested in this. He also understands this truth, but he does not It is believed that there will be enough power to take a person to the sky.

He is interested in iron furnaces...

The best craftsmen of this era were recruited by the government, and the official handicraft industry has always occupied the dominant position of ancient handicraft industry, representing the highest level of production skills.These craftsmen are concentrated in the workshops set up by the government, using the raw materials provided by the government, and under the supervision of the workers, they make and process the products designated by the government.

Weapons supervisors, generals as supervisors, and so on.

Their profession is hereditary, and they have worked for the government for generations.

But Li Tai never expected that Fang's iron-smelting furnace would be so advanced...

As the furnace temperature gradually increased, the molten iron melted and rolled and burned in the furnace, releasing a large amount of smoke and dust, and the flames rose into the sky. Li Tai, who was standing not far from the furnace, was blushing as he watched the air blowing under the blow of the blower. The iron smelting furnace that made a whining sound almost popped out my eyes!

Ordinary iron smelting furnaces emit pitch-black smoke. If there is no wind, people can choke to death within a radius of more than ten feet. Wherever it is like in front of me, the smoke and dust rushing out of the chimney are full of flames, and sparks fill the sky. Fly!
Li Tai from Bo Wen Guang Ji understood that this is a scenario that can only occur when the furnace temperature reaches an unprecedented height.

And the quality of iron has a great relationship with the temperature of the furnace. Needless to say, the quality of iron produced in this furnace must be excellent!In other people's iron works, it is not always possible to make such a good furnace of iron in a lifetime!
Li Tai looked around and went out to some professional blacksmiths to stare at the iron-smelting furnace. Basically, no one was interested in such a high-quality iron material that was about to be released. It seemed to them that this was just a common occurrence. Furnace Iron, I've been tired of watching it for a long time, and it's more interesting than Fang Jun's super kongming lantern...

How could this be?
Could it be that the Fang family’s iron-making furnace can already achieve this level of iron in every furnace, otherwise how could the craftsmen treat it so plainly?

This is incredible too!
Li Tai became more and more curious, and kept walking around the iron-making furnace, looking at the novel blower, the iron frying furnace buried in the ground, and the grooves at the bottom of the iron-making furnace... Like a curious baby, Look at this, look at that, and occasionally grab a craftsman and ask questions.

The craftsman knew that he was His Royal Highness, and he was dragged by his clothes, and his face was so pale that he almost died, but he kept his mouth shut and didn't say a word about Li Tai's question.Being asked in a hurry, I had to cry and say with a sad face: "My lord, do your best, this is the top secret related to our iron-making furnace, and I wouldn't dare to say it if you kill a kid! If you really want to know, you might as well ask Erlang. All of our stuff was created by Erlang alone, and many of us don't know what the truth is..."

Li Tai was helpless and knew that he was a little rash.

As strange as Fang's iron-smelting furnace, it must be kept strictly confidential, otherwise everyone else will learn, how does Fang Jun, a financial fan, make money?
But he is also stubborn, doesn't he say nothing?That's ok, this king doesn't ask any more, this king just watches, okay?

So, Li Tai crossed his hands and stood aside, staring at every step of the iron-making furnace.

The craftsmen did not dare to say anything.

After all, it is for the prince, and he is a fairy-like figure in the past. Who dares to go up and drive him away?Besides, since this one was brought by Erlang, I think Erlang is not afraid of him taking a look at him. Since Erlang doesn't chase people, then let him be.

But then again, the iron-smelting furnace designed by our Erlang, who can learn it just by looking at it?

no kidding...

The craftsmen pretended that His Royal Highness King Wei did not exist, and put on several layers of thick kudzu clothes for protection. Holding long-handled iron pliers, they opened the valve of the taphole at the lower part of the blast furnace, and the orange-red molten iron broke through the gate happily. Pentium flows out.These completely melted molten iron is mixed with slag. The iron is heavy and the slag is light. Most of the slag floats on the surface. Large pieces are blocked on the groove by a baffle made of pig iron. Slag scraped aside.

Seeing this scene, Li Tai admired Fang Jun to the extreme.

Li Tai has never smelted iron, but this does not prevent him from knowing that the biggest problem in iron smelting is furnace temperature.If the furnace temperature is not enough, the iron ore cannot be completely melted, so the quality of the iron material produced is generally not very good.

But raising the furnace temperature is a super difficult problem, and no master craftsman can come up with a perfect way to improve this.

And this iron-smelting furnace in front of me, just a furnace of iron, will reach the level of complete melting, how high is this temperature?Looking at the orange-red molten iron radiating dazzling light in front of him, Li Tai's heart felt as if he was scratched by a cat!
How did they do that?
At this time, the groove for casting has been opened, and the mold has been placed on the ground. The molten iron from the large slag is removed, and it flows into the mold from the groove and casts pig iron ingots one by one.After a while, two hundred pig iron ingots were cast under Li Tai's eyes.

Li Tai didn't know how to describe his mood anymore, he was completely stupid!

Changsun Wuji is his uncle, although the relationship has not been too close, but before he participated in the fight for the reserve a few years ago, he still went back to his uncle's house to play every now and then. He also went to the iron factory in Chang'an city. .I remember the largest iron-smelting furnace in the eldest grandson's family at that time. When the furnace produced thousands of jins of iron, he grinned with joy. It was all money!
But there are nearly 1 kilograms of them lying in the ground, right?
This is not over yet!

The molten iron in the furnace was not fully released and apparently had a use.

Li Tai concentrates, watching the craftsman close the groove for casting and open another groove leading to the iron frying furnace. The strange iron frying furnace is nestled under the horizon. I can't see what it looks like, and the molten iron flows by itself. Enter the iron frying stove that has been burning for half an hour.

The craftsman turned on the stirring equipment, and the large disc on the top of the furnace slowly rotated, driving the wrought iron sticks to stir in circles in the molten iron, and the molten iron tumbled.Li Tai nodded secretly. This kind of equipment is simple in design, but very practical. It is obviously a hundred times stronger than the role of manpower.

As soon as the molten iron that had just flowed in from the iron-smelting furnace was stirred, it reacted violently. The molten iron immediately boiled, and bubbles gushed out, pushing the slag to the side of the furnace and accumulating.The molten iron in the iron frying furnace gradually becomes thicker, from clear soup to sauce, and finally gathers into molten iron balls.

The craftsmen pick up a piece of iron with long-nose pliers, put it on the cutting board, and hit it with a sledgehammer.Because it was winter, the river was already frozen, and all the heavy hydraulic forging hammers in the row next to it were resting. Li Tai vaguely remembered seeing this kind of thing in a book, but couldn't remember it.

An old craftsman was holding a piece of wrought iron, and two apprentices with big shoulders and round waists rounded their arms. The hammer with the size of a child's head pounded repeatedly, causing sparks to splash out.The iron mass gradually cooled and hardened, and the hammer smashed the sparks, but left no trace. This piece of iron was tough and hard, and it was obviously a piece of fine steel!

The old craftsman smiled and said: "This piece is good, the steel mouth is excellent. Wasn't Erlang's horizontal knife snatched by Mr. Cheng a few days ago? Looking back, the old man made another one for Erlang himself! It is estimated that this piece of steel is The quality of the knife is much better than that of the batch, and this knife should be sharper when it is cast!"

Li Tai walked over, ignoring the royal appearance of the prince, he bowed down and looked at the piece of steel carefully, admiring in his heart, looking at this fineness, it is a rare good steel!
His Royal Highness King Wei straightened up, turned around and shouted at Fang Jun, "This piece of fine iron was bought by the king, and I will send it to the palace!"

Fang Jun was discussing with Liu honestly how to design and install the exhaust valve of the airbag. Hearing this, he came over with Princess Jinyang on his back.The little girl seems to feel that Fang Jun's broad back is warm and comfortable, but she can't even rest on it...

Fang Jun is not afraid that Li Tai secretly learns the technique of ironmaking.

I don't know coking, I don't know what carburizing is, I don't know how to preheat the air, I don't know how to raise the furnace temperature, I don't know how to prepare irritating materials, I don't know how to make graphite crucibles... I just learned the way an iron furnace looks like. It has its shape without its god, and it is impossible to make steel of the same quality.

The knowledge here, spanning thousands of years, has grown!
Looking down at the piece of steel that Wang Xiaoer was holding, he asked Li Tai, "Why, Your Highness likes this piece of steel very much?"

Li Tai said: "It's really good. It's rare to see such a good steel mouth. If you use it to create a treasured sword and a sword, it will definitely cut iron as sharp as the mud. It is a rare weapon! How about it? The king bought it!"

"Haha" Fang Jun smiled nonchalantly, and said casually, "I can't store this quality steel in my warehouse. Your Highness likes it. Just take it and say it's not worth the money, how vulgar?"

This stuff is not rare in my family, if you think it is a treasure, I will give it to you for nothing, no money...

Li Tai held his breath in his chest and almost didn't catch his breath.What this king likes, I want to buy it back at any cost, but it is like a wild vegetable, and I throw it away...

Fang Jun, this bastard, has reached the highest level of slap in the face?
