Live as the emperor

Chapter 274

"What?" Please forgive me, Chen Guang has never heard of such a thing.

Fortunately, there is a universal live broadcast room.

While dealing with Ah Fu, he sneaked into the live broadcast room and asked, "Come on, come on, who knows what this is?"

Needless to say, in fact, someone has already been looking for the answer. Just after he finished asking the question, someone posted these two words. Chen Guang was very surprised when he saw it, "Damn it, these two words So complicated? What the hell is it?"

A netizen said: "It's the original version of the bellows, blower."

橐 is a wind bag made of cowhide; 龠 originally refers to a blowing wind instrument, but in the word it is a metaphor for a wind pipe.According to historical records, it has existed since the Warring States Period. "Laozi? Dao Jing" uses the metaphor of the space "between the heaven and the earth, is it still like a stick? It is empty and unyielding, and it moves more and more."

There is an image of the smelting iron in the iron smelting stone of the Han Dynasty unearthed in Teng County, Shandong Province. It has three wooden rings, two round plates, and is made of leather.When the leather is pulled apart, the air enters the leather through the intake valve; when the leather is compressed, the air in the leather enters the air duct through the exhaust valve, and finally enters the smelting furnace.The substantial development of the iron-smelting technology in the Han Dynasty was closely related to the improvement of the power of the shovel.

Well, Chen Guang expressed his understanding, this is the predecessor of the bellows.

In the past, every household in rural areas had a brick stove with a bellows next to it.After filling the pot with water, light the firewood and put it into the mouth of the stove. Pull the bellows with your right hand and add firewood with your left hand.It consists of a wooden box, a push-pull wooden handle and movable wooden box.When the movable wooden box is opened by hand, the air enters the box through the air inlet; when the wooden box is compressed, the air in the box enters the air duct through the exhaust port, and finally enters the smelting furnace for burning fire and cooking.

It's also drunk, a bellows that is so simple that it can't be more simple, but it is as tall as a person, and two people are required to operate it, what a mess.

Chen Guang has already decided to go to Jin Kebi after he leaves here, and ask him to make a batch of bellows and replace all the bellows.

The ground here is all soil, unlike the stone slabs outside, this is for the convenience of digging soil to make molds.

Chen Guang once had a junior high school classmate whose family owned a brick factory. He went there to play and saw that they just put mud into a rectangular wooden frame, tamped it with a hammer, took it out to dry, and threw it into the fire. To burn.The same is true here, but the block norm method is used.It is to first make an identical thing with wax, such as a sword, and then wrap it with soil, leaving small holes.Then pour the molten iron that has become liquid, the wax melts, and the molten iron takes the place of the wax. After cooling, an iron sword is ready, and then it needs to be polished.

Everyone was busy, Chen Guang looked around and came to the stove that belonged to Ah Fu.

Ah Fu's stove is larger than that used by other people, and there are a total of five craftsmen working for him, and the other stoves are standard configurations for three people.

"His Royal Highness, there are two types of iron: pig iron and wrought iron. Pig iron is hard, wear-resistant, and has good castability, but pig iron is brittle and cannot be forged. After pig iron is forged, it becomes wrought iron. It is very soft and has good plasticity." , good ductility, can be drawn into wire, low in strength and hardness, easy to forge and weld. But if it is made into a pot for cooking, pig iron must be used. It transfers heat slowly and evenly, but the pot ring It is thick, the lines are rough, and it is easy to crack. It is not an easy task to achieve the thickness required by His Royal Highness."

Afraid that Chen Guang would not understand, Ah Fu first explained to Chen Guang.

Chen Guang didn't point it out, and after he finished speaking, he said: "Well, I know, let's try it first."

"it is good."

Ah Fu naturally would not refuse, and made the wax mold himself.It was a block of wax, and then Ah Fu unfolded the drawing given by Chen Guang, and slowly carved out the shape of an iron pot.

When Chen Guang saw it, hey, I'll go, this fully transparent iron pot looks very good.

Immediately afterwards, it was brushing the soil, sticking a very delicate soil on the iron pot made of wax, then drying it, and brushing another layer, and after several layers of brushing, the original iron pot could no longer be seen. It looked like it stopped.

Then make the mold, and then pour the red hot molten iron into it.

After more than an hour, the mold was separated, the soil was removed, and an iron pot designed by Chen Guang appeared.

However, this cast iron pan cannot be used.

"It's too thick, we need to make it thinner." Chen Guang said after looking at it.Although this is very thin compared to that kind of big iron pot, it is still very different from the one used for cooking in the kitchen of the 21st century.

Ah Fu said: "If it is thinner, I am afraid it will not be so easy to make."

Because this iron pot can only be formed at one time and cannot be hammered, it is necessary to make all the radians when making the model.

Chen Guang said: "It's too thick."

Ah Fu didn't say anything more, and started the second attempt again. This time, the iron pot he carved with wax was even more crystal clear.

If Chen Guang hadn't put all his thoughts on the iron pot, he would have praised it and said that it was simply a work of art.

The second firing takes a shorter time because less molten iron is needed.

After pouring, Chen Guang still thought it was too thick, even though it was much thinner than the one just now.

In fact, this iron pot, to be honest, can still be used if you make a little effort. The small iron pot that Chen Guang is using now is of this level.However, the iron pot that was built at that time was directly contacted by the military supervisor, and it is not known who built it.At present, the iron pot in Chen Guang's hand is very close to that one, and it will be the same after polishing.

But Chen Guang was still dissatisfied, because it was still far from what he had imagined.

Ah Fu naturally would not stop, he started the third casting.

But this time, it didn't go well, because something went wrong when casting the model in wax.

Because it is curved, all the weight will be borne by the most central point. Ah Fu made it too thin, and it has not been carved yet, and the center has already rotted.

Obviously, this time, it failed before firing started.

Ah Fu was also helpless, and said to Chen Guang very ashamedly: "His Royal Highness..."

As soon as he opened his mouth, he was interrupted by Chen Guang, who said with a smile: "It's okay, this method won't work, let's change it."

He opened the live broadcast room, and the things that the ancients couldn't solve, let the wisdom of the modern people.

Oh yes, and Baidu.
