Fighting The Galaxy

I really don't understand. What is Bowman doing in this kind of ceremony? Just before starting to burn the molten iron in the first furnace, Bowman took the crowd and actually started the sacrifice furnace!

Bowman's upper body was naked, and various beautiful patterns were painted on it. Then, in front of the stove, a large stone was set up as a table. Bowman kept talking about what is the spirit, Earth spirits, words like immortals appearing fast on the fire.

When he read it, all the people below knelt down on the ground, and the ceremony was very solemn. Until the end, Bowman slaughtered a pheasant that he had already caught, and cut off his head and chicken neck all at once. The blood was pouring continuously, he took the chicken body and poured the blood along the stove in a circle.

This disapproved Clark's mind, and felt that it was strange to fooling these primitive people like this, but Joule soon understood Bowman's meaning.

If you want to rule these primitive people, you must cultivate their loyalty. The usual method is not easy to use. This way of pretending to be fooled is the most efficient.

For example, now, Bowman is so tossed, the holy water that comes out last, and the weapons that come out are granted by the gods. When they get these weapons, they will certainly be loyal to the gods. It will also bring a certain degree of danger. When you have no way to use modern weapons, this cold weapon is the most efficient way.

"Open the oven!" After tossing through the ceremony, Bowman also felt a little tired. This body was not good enough, and he couldn't eat it.

With his command, the potter's wheel over there started to stir, slowly propping the raw materials up to the top of the furnace and pouring it down.

The raw materials are all mixed. Those limestones were smashed with stones, and it took a lot of effort to break them. The iron ore sand has been rinsed many times, and finally the best texture and high quality are obtained. charcoal.

It is now that Bowman has seen the production process of charcoal.

Joule lets people cut down the freshest branches, then dig a large shallow hole in the ground, ignite these branches, and when these branches burn, they are immediately covered with soil, otherwise they will all be burnt to ash, now, Covered with soil, it lacks oxygen, so that it can remove moisture and decompose organic matter. When it is extinguished, the soil is chopped apart, and a batch of high-quality charcoal is obtained.

When covered with soil, smoke kept coming out of the carbon pile, which scared the primitive people and thought it was a ghost.

Everything was put in layer by layer. After the charcoal in the first layer was put in, a little kerosene was poured, and Joule became religious.

"Great cosmic deity, please give this world new power, now, please Vulcan!"

Since the last time it burned, someone has been adding fuel to the fire, letting the fire burn there and burning. Now, Friday, the torch is raised religiously, and it is handed over to Joule, and Joule hands it to Bowman again. The fire was stuffed into the stove.

The charcoal in the stove started to burn! At the top of the stove, black smoke came out, and the black smoke became weaker and weaker. When the black smoke disappeared, it meant that the inside was burning!

"The blast begins!" Shouted Joule.

Several primitives have been prepared for a long time, and several people pushed the skin sac together. Every time they pushed, the flames in the furnace burst out, and the flames could emerge from the high chimney.

From a modern point of view, a complex chemical reaction is taking place inside the furnace at this time. Lime is decomposed into lime and carbon dioxide at high temperature; lime and carbon react to form calcium carbide and carbon monoxide; yes, what is really needed is actually It's this carbon monoxide! Iron tetroxide is reduced to iron by carbon monoxide at high temperature, and carbon dioxide is released at the same time; in this way, the elemental iron is reduced from the compound!

Of course, other reactions are also in progress, and there are a lot of impurities in it, such as the reaction of lime and impurity silica to produce calcium metasilicate; the reaction of lime and impurity phosphorus oxide to calcium phosphate; these impurities are all slag, Start to sink down, the molten iron floats on it, as long as they are separated, you can extract it!

auzw.com "No, the furnace temperature is not enough, continue to add carbon!" Joule shouted.

If you want to restore the iron, it needs high temperature. Under the current situation, the temperature is not high enough. Continue to add firewood!

Baskets of charcoal were rolled up and fell, and the black smoke rose again.

"Flame, blast! Quick, replace!"

Once the stove starts to burn, you must go all out. Otherwise, it will become waste. At this time, the blasting group has been exhausted and replaced with a new group. Continue to Blast in the stove!

"No, it's not enough!" Joule said.

Using charcoal is still not okay. It can now be observed that the iron cannot be melted into molten iron. If there is no molten iron, it cannot be poured. If you can't find coal, you can't burn such high temperatures if you make coke.

How to do? The grand ceremony just took place, should we give up now?

of course not!

"Open the bottom!" Joule shouted.

In the history of mankind, at the beginning, it was impossible to burn with coal. After that, the craftsman still has his own ingenuity, as long as the impurities inside are separated!

This is the role of flux, which reduces iron oxide to iron and forms separable calcium salts with impurities. Although iron has a high melting point and cannot be melted, some metals and impurities with lower melting points will flow to the bottom of the furnace in the form of slag!

Now, when the following mouth is opened, I instantly feel my body is scorched on Friday. How hot is that thing? Will it be as hot as the sun above?

He quickly backed away a few steps, watching the **** flowing out.

The **** has flowed out, and the iron with a higher melting point that cannot be melted out, although it cannot flow out like the planned molten iron, has at least been softened, condensed into lumps, and left in the lower middle of the furnace.

now what? What should I do?

"The servants of the fearless God, now, it ’s time to test you, rush over immediately, do n’t be afraid of the heat, break the furnace with stones, take out the treasure that God has given us to us, pick it out, and do n’t use your hands or body Contact, otherwise, you will be punished by God. "Joule said.

Now that the ironmaking process is over, quickly break the furnace and remove the insoluble **** and char in the white hot sponge-like iron smelting block!

Fortunately, there were preparations in advance. Next to them, some long stones were prepared as sticks.
