Chapter 121： Xin Hang

No one knows how much iron is contained in these iron ore.

But on the system side, there are still five units of ore, and one unit of iron is smelted. The same is true for aluminum, and the same is true for all other metals.

Needless to say, there must be huge losses in it, but Ankai has no choice, because if he doesn't pass the system, he can't prepare iron and aluminum by himself.

In modern society, the methods of preparing metals are completely different from those in ancient times. Among them, the preparation of elemental iron generally uses smelting methods. Using hematite or magnetite as raw materials, it reacts with coke and co-solvent in the smelting furnace. The coke burns to produce carbon dioxide. When carbon dioxide comes in contact with excess coke, carbon monoxide is formed. The carbon monoxide reacts with iron oxide in the ore to form metallic iron. . Calcium carbonate is added to generate calcium oxide at high temperature to remove silica from iron ore, and finally generate slag.

If this process is to be completed in reality, it can be said to be very troublesome and requires too much professional equipment, knowledge and workers, which is not something Ankai can play at all.

Of course, if a laboratory method is used to reduce iron oxide with carbon monoxide to prepare a small amount of elemental iron, it is also possible. But the problem is that the output is so small that it is far from the so-called efficiency.

It is simply impossible to support the development of the shelter.

This is especially true of aluminum. Sacrifice like lolxsw.com sacrifice like

In previous earth history.

In 1854, the French chemist Deville mixed bauxite, charcoal, and table salt, and then heated it with chlorine gas to obtain sodium chloride and aluminum oxide double salt. Then the double salt was melted with excess sodium to obtain metal aluminum. In 1886, Howe of the United States and Hylandt of France independently produced metallic aluminum by electrolyzing a mixture of molten bauxite and cryolite, which laid the foundation for large-scale production of aluminum in the future. The modern large-scale production of aluminum requires eutectic electrolysis of its oxide and cryolite. The whole process includes dissolution, filtration, acidification, filtration and burning, and finally electrolysis. The whole process seems simple, but in fact it is very complicated. ,

What's more terrible is that, whether it is iron or aluminum, if it is prepared by means of modern society, a large amount of various chemical materials need to be used, which are completely impossible to make by Ankai and the others.

Not to mention that they don't have any real chemistry talents, at most they are at the level of a high school graduation, how can they do these things.

So even if you know that the production of aluminum and iron through the system will consume a lot of raw materials, and the input and output are completely disproportionate, Ankai has no choice but to accept this method.

On average, a mine can produce five units of iron ore an hour, which is equivalent to one unit of iron, and one unit of iron can’t be done by training a dagger, let alone making weapons. So it’s actually the most convenient to go directly to the outside to dismantle all kinds of metals that have been smelted long ago. The efficiency is actually not as high as which is lower. After all, going out to collect is risky, and it needs to be transported back a little bit. Mining directly in the shelter eliminates the previous processes.

The mine still doesn’t know that it’s tired, as long as it’s kept on, it can keep working, which is a bit of fuel consumption.

"Right, oil!"

Thinking of this problem, An Kai has a headache again.

Oil, I thought it was very durable before, but now I gradually feel that the oil is not enough.

Before Ankai and the others went out several times, they did collect a large amount of oil, which can be used to provide power to generators, to provide power to equipment such as mines, and to provide energy for cars... It can be said that the importance of oil It is the most important thing in the shelter.

This is really no one.

Ventilation and air purification need electricity, daily life needs electricity, water purification needs electricity, sun lights need electricity, farms need electricity, entertainment life needs electricity... and electricity is driven by oil, no Oil, among other things, the shelter immediately lost sight of the fingers, the oxygen was cut off at any time, the clean water was used up at any time, and the food immediately lost the sun lamp to supplement the sunlight.

It can be said that as long as there is a power failure, none of them can survive. Bxwx

Fortunately, the amount of oil used by various equipment was not too much, mainly because the electricity consumption was decent.

He also opened the mine for a day but not a day before, mainly because he felt that there was not such an urgent need. Needs are naturally there, but they have not yet burned the eyebrows, so you can take your time step by step.

In fact, the best way is to conduct mining and collection simultaneously, just as Ankai has been doing before.

It's a pity that time is waiting for no one, and the zombies outside are mutating like a raging fire. How can he continue to waste time here?

As a result, there is a new mine suddenly. The power consumption of the mine is actually very large, and now it is not possible to go out to collect, the demand for materials has further expanded, and the mine can only operate around the clock.

In this way... the problem of oil was immediately before me.

One point is that if the generator uses nuclear power, it is really good. It is also a clean energy source and the power generation capacity is very fierce.

But it's a very, very pity... he is not level enough.

And there is no fuel The materials for making nuclear power generators are actually not enough...

"Why are all pits!"

An Kai wailed in his heart.

I felt time and time again how well my sanctuary developed, how large and healthy it was, and could survive endlessly.

As a result, when he noticed the oil, he realized that the thing he lacked most was actually this stuff.

Food can be an asset, ore can be mined, what about oil?

This is a problem that has never been encountered before.

There are still a few gas stations in the riverside area. They have observed when they went out. There must be oil in the oil depot. As for how much there is, it’s hard to say, but it’s always enough for a while. But the problem is that he is uneasy in the current river bank area, and Ankai and the others dare not go out casually. He had a good deal of the remaining oil. If he fully supports mining without affecting crop production, even if the other functions of the shelter are reduced to a minimum, it can only last for more than half a month.

If you want to continue to extend the time, other aspects will inevitably be affected. To be honest, An Kai really doesn't want to see this scene.

"You have to go to other cities to see it."

An Kai didn't believe that the group of people who made and controlled the zombies had strongholds in every city, which was too exaggerated.

In addition to the city, the highway rest point is also a gas station, and there should be oil left.

So everyone still has to go out, but this time the goal is not the riverside area, but other cities. Mi He Mi

Thinking of this, he immediately came to the warehouse, found a map of this province, and began to determine the next course of action.
