When Pan Geng moved to Yin, I initiated Jian Shang

Chapter 118 Iron Smelting

At noon, the first batch of mine was delivered quickly.

Xin Qu got a set of rollers and stone mills from Yuquan. He first asked the slaves to break the big rocks, then smashed them into smaller pieces with a treadmill, and then placed them under the rollers to let the horses move.

Continuously grinding it until it was relatively fine, Xin Qu sifted the powder and weighed about thirty kilograms.

Then sprinkle them on the charcoal pile, then light a fire, let the charcoal burn all unnecessary substances in the minerals, oxidize them and then reduce them.

Especially sulfur.

In China's iron smelting industry, the most important thing to pay attention to is the sulfur content.

Iron containing too much sulfur is too brittle.

The main purpose of roasting and oxidation is to remove sulfur.

This also takes time. Xinqu asked the slaves to watch the fire, let them burn slowly, and then went to work on the blast furnace.

I went to the pottery workshop and took away more than 1000 adobe brick embryos that I had ordered three months ago and had been left to dry in the shade.

Then build an earth furnace in the workshop, leave a mouth for slag at the bottom, and place a wooden wind turbine in the middle.

A hole is dug in the middle of the wood similar to the side view of "Peppa", and then the fan blades are installed inside. A wooden stick is used as a link, and then a straw rope is wrapped around the wooden stick. People take turns pulling left and right, and use the rope to drive The wooden rod rotates, and the wooden rod drives the fan blades, and the fan blades blow air into the air inlet of the earthen furnace, continuously heating the furnace.

While Xinqu was busy, Gulu Xiaogui appeared behind him at some unknown time. He looked at the baking pit and the busy Xinqu: "Have you really found evil gold?"

"Yes." Xin Qu stood up after hearing the words and wiped the sweat from his forehead with his forearm that was not stained with mud. "We are experimenting. If it succeeds, bronze can only be used to make bearings, while iron will be given priority to make armor to further improve The strength of the clan.”

"Haha, it seems that you have made up your mind. However, you still have to keep the armor your uncle gave you. It is your uncle's wish, so don't waste it."

Gulu Xiaogui reminded Xin Qu that some things are more valuable than bronze and can be of great use at critical times, so don't use them foolishly.

"Don't worry, I know." Xinqu smiled and continued to work on the earth furnace.

He needed to build two.

A short tool furnace used to melt molten iron after roasting, and then the crucible needs to be fired.

A high one is used to restore the slag after roasting. After all, there is no refractory brick technology now, so the problem can only be solved through two processes.

Xin Qu calculated it, and he didn't know how much temperature the blast furnace could withstand. It might need to be rebuilt after three uses.

After finishing the stove, it was already afternoon. Xinqu took an iron dagger hidden at home, and took the "crucible" from the pottery Ren. It was actually a shade-dried porcelain clay embryo. Porcelain clay was too hard to find. There was no Before the kiln, it was difficult to make ceramics, so Xinqu spent a lot of effort to find some usable kaolin from a nearby hill.

Xinqu placed the "crucible" in a short stove, covered it with charcoal, then artificially sealed the top, and placed a clay pipe at the burning position of the crucible to open a fire outlet laterally.

The purpose is to artificially suppress the flame into a horizontal fire, which can make up for the shortcomings of insufficient temperature when firing ceramics.

Reduce heating costs, otherwise the charcoal will definitely not be enough and more will need to be added.

After starting to heat, Xin Qu glanced at the orange-red flame sprayed out of the pottery tube and frowned slightly. Is it only a thousand degrees faster?
Should be enough.

Xinqu can only keep people at this temperature for a while, and then try to speed it up.

Finally, a glowing white flame appeared, a thousand-degree breakthrough, and Xin Qu nodded with satisfaction.

"Hiss, this firepower..." Gulu Xiaogui's eyes widened, "You kid, you have this labor-saving method, why didn't you tell me earlier!"

The heat wave in the room came one after another. Xin Qu wiped his sweat. It was the first time that Shu Dagu next to him felt that the flames could have such power. Every time he took a breath here, he felt that his brain was alarming. , let him run away quickly!

terrible!

Xinqu laughed at Gulu Xiaogui's annoyance and said: "The temperature is indeed very high, but it can't last long. After a few hours, you will be exhausted to death. Besides, such high temperatures are used to melt metal. , there is no crucible to take over, won't it fall on the slag once it is burned? Aren't you going to have to burn it again? Isn't this a waste of time?" When Gulu Xiaogui heard this, he also felt that it was reasonable, so he did not complain to Xinqu again, but He stared at the furnace intently. With this thing here, there were so many things he could smelt!
Xin Qu also knew it well, so he took the iron dagger when he had time.

This iron dagger was a trophy he got from killing a cannibal tribe that robbed them on the business road. It was also because of this thing that Xin Qu was determined to engage in iron smelting.

After all, the appearance of this pig iron dagger means that some tribes have mastered the restoration of iron.

Still very crispy though.

Xin Qu grabbed the handle of the knife and exerted force, and the entire pig iron dagger broke into three sections in an instant.

I can only say that it is okay to cut meat, but if it really goes to the battlefield and encounters bronze, it will be scrapped directly.

It's not even as hard as stone.

But this thing is better if it is crisper. I will try to make steel directly later.

After all, he had heard popular science from netizens before, saying that most of the iron smelted in blast furnaces was wrought iron.

So this is pig iron in your hand. After melting it and pouring it into the wrought iron water and stirring it, you should be able to burn "steel" directly.

It doesn’t matter if it’s true or false, it’s just a test anyway!
Xinqu is still very patient.

If it can come out directly in one breath, it will not be a loss in blood.

"By the way, I'll get a mold for making daggers. Bronze ones can be used." Xin Qu said to Gulu Xiaogui.

"go Go."

Gulu Xiaogui drove Xin Qu away, and he squatted by the stove and looked again and again.

It was already dark, but the white light was still bright.

Shu Dagu followed Xin Qu out. The hot autumn wind caused by the wildfires made him feel cooler than ever before: "It turns out that forging metals, one has to be busy in such a harsh environment. Compared with them, this year's severe drought is even worse." It’s pretty cool.”

"No, the temperature is thousands of degrees at every turn. When you work here for a long time, you need to replenish a lot of salt and other organic matter, so Gulu Xiaogui likes to drink wine here. Wine, especially fruit wine, can replenish a lot of things. Yes, and add some salt, it’s very refreshing.”

Xinqu arrived at the bronze smelting area. As soon as the two of them stepped in, the temperature immediately rose.

"Hiss... you don't have to give in too much!" Shu Daquan wiped the sweat from his forehead, "I finally know why the Dayi Chamber of Commerce has always prioritized the creation of US dollars. Emotional evil money requires more firepower than US dollars. It's worse. You need a lot of firepower from outside!"

"Yeah. The difference is at least two hundred. Pure copper requires more than 1000, bronze has a lower melting point, but it also costs [-], and pure iron requires [-]. With a slight adjustment, the furnace can press it to [-], so both The difference is at least two hundred.

And we only need one hundred to boil a cup of water.

When charcoal burns, it can burn up to one thousand and two thousand, so charcoal is the best fuel we can get at this stage. "

Xinqu looked in the northeast direction: "Now, collect as much as you can. This fire really saved me a lot of time."

Shu Dagu nodded, and when Xinqu found the mold and left, when he stepped out, cold sweat suddenly ran down his forehead.

Looking at Xin Qu's back, he felt more and more that this guy's work was just like spinning. Each thread seemed to have nothing to do with it, but once it was strung together, everything was related.

This mountain fire burned countless charcoal. Charcoal is also needed to smelt evil gold. The tribe also needs charcoal to survive the winter. Charcoal is also produced by burning wasteland. It is easiest to use fire to prevent the enemy from attacking.

So, everything is so logical? !

"How did he see so far away! Is this still a human being?"
