Chapter 120： 2nd mine

An Kai first made a mine.

The land under their feet has the highest aluminum ore content.

But this is not to say that there is only aluminum.

In fact, in nature, a lot of metals are scattered in soil and rocks, and you may pick up a handful of soil from the ground to contain various metal foams.

It's a pity that this degree of metal accumulation is too low, too low, too low, and it doesn't even have the slightest mining value.

In addition to aluminum, there are other metal veins near the shelter. Before the mine was lowered, only aluminum was mined. That is because the reserves of aluminum around here are the highest, forming a complete vein that can be mined in large quantities. Moreover, Ankai set up automatic mining equipment for mine equipment at that time. The advantage of automatic mining is that the mining gold probe can automatically search for the minerals with the highest reserves within a certain range. This can help Ankai determine the main specialty of the minerals surrounding his shelter at the first time. If he has relevant needs, he can adjust the development direction of the shelter in a timely manner according to the degree of mineral enrichment.

Aluminum is still very useful in shelters.

Aluminum and aluminum alloys are among the most widely used and most economical materials in both worlds.

In the previous life, aluminum output has surpassed copper output in 1956 and has always been the first among non-ferrous metals. Before the rebirth of Ankai, the output and consumption of aluminum were calculated in ton, and the consumption was second only to steel, and became the second largest metal used by humans; and aluminum is very rich in resources, and Ankai has forgotten where he saw it. It is said that the mineral reserves of aluminum account for more than 8% of the constituent materials of the earth's crust.

Aluminum's light weight and corrosion resistance are two outstanding features of its performance.

Light weight means low density. Although it is relatively soft, it can be made into various aluminum alloys, such as duralumin, super duralumin, rust-proof aluminum, cast aluminum, etc. These aluminum alloys are widely used in manufacturing industries such as airplanes, automobiles, trains, and ships. In addition, large amounts of aluminum and its aluminum alloys are also used in space rockets, space shuttles, and artificial satellites. A supersonic aircraft is composed of about 70% aluminum and its aluminum alloy. Aluminum is also used in large quantities in ship construction, and the amount of aluminum used in a large passenger ship often reaches several thousand tons.

Corrosion resistance makes it often used to manufacture chemical reactors, medical equipment, refrigeration equipment, petroleum refining equipment, oil and natural gas pipelines, etc.

In addition, thermite is often used to smelt refractory metals and weld steel rails. Aluminum is also used as a deoxidizer in the steelmaking process. Aluminum powder, graphite, and titanium dioxide are uniformly mixed in a certain ratio, then coated on the metal, and then calcined at high temperature to make high temperature resistant cermet. It has important applications in rocket and missile technology.汜减bX　W*X　汜

The reflection performance of aluminum plate to light is also very good. The reflection of ultraviolet rays is stronger than silver. The purer the aluminum, the better its reflection ability. Therefore, it is often used to manufacture high-quality mirrors, such as solar cooker mirrors.

There are some things that are not available to the shelter, but some are necessary for the shelter. Therefore, after finding the aluminum ore, Ankai did not change the mining direction of the mine, and still vigorously mines aluminum ore. Nowadays, the shelter lacks other materials, except aluminum.

So this second mine, he will aim at the metal he needs most at the moment-iron!

Iron is the most used metal in human history, none of them, and its synthetic steel, which is also the most used alloy in human history, is also not one of them.

This thing is really a wife and wife too important, almost all aspects of human life can be used.

Of course, this is not to say how important iron itself is. In fact, as a metal, iron is not the best in performance. No matter what, there are almost substitutes. However, the advantage of iron lies in its large reserves, large output, easy mining, easy smelting, and very low manufacturing costs. Many metal creations, if a large amount of iron is used, can reduce the cost to a relatively low level. On the contrary, the cost may be so high that the performance may be better. What's the point?

How big is the role of iron?

Simply put, first of all, it can be used in pharmaceuticals, pesticides, powder metallurgy, thermal hydrogen generators, gel propellants, combustion activators, catalysts, water cleaning adsorbents, sintering activators, powder metallurgy products, and various mechanical parts Products, cemented carbide material products, etc.

Secondly, pure iron is used to make iron cores for generators and motors, reduced iron powder is used in powder metallurgy, and steel is used to make machines and tools. In addition, iron and its compounds are also used to make magnets, medicines, inks, pigments, abrasives, etc. Sacrifice as 7huan.com Sacrifice as

Iron can also be used as a reducing agent. Used for iron salt preparation. It is also used to prepare electronic components.

In addition, it is used as a filler for epoxy adhesives in adhesives to prepare casting repair adhesives. Iron is also often used as a reducing agent. It has a wide range of uses in the electronics industry, powder metallurgy, and machinery industry. FHY80.23 is mainly used for oil-impregnated bearings. FHY100.25 is mainly used for medium and low density mechanical parts. HFY100.27 is mainly used for high-density mechanical parts.

However, this is not the full effect of iron.

Unlike aluminum, which is a toxic metal, iron is also an indispensable element in the human body.

Of course, there is still a difference between iron element and elemental iron, but they are actually the same thing.

The element iron is one of the essential elements that constitute the human body There are about 4 to 5 grams of iron in the adult body, of which 72% is in the form of hemoglobin, 3% is in the form of myoglobin, and 0.2 is in the form of other compounds. Exist, the rest is reserve iron. Reserve iron accounts for about 25%, mainly stored in the liver, spleen and bone marrow in the form of ferritin.

It can be said that no matter what form iron exists, it is indispensable to human beings. Mi He Mi

Before, An Kai didn't think it needed iron to protect everything. After all, if there is no underground, it can be found on the ground. He didn't take this matter to his heart.

Even considering the changes in the external environment after the nuclear explosion, he didn't feel that he had to get an iron ore out of it. But the situation is different now. To deal with the powerful zombies and the humans behind the zombies, all aspects of the shelter must be strengthened and upgraded. At this time, the amount of steel has increased, and there are various alloys, and the value of iron has suddenly increased. Not to mention whether you can collect so much by going out alone, even if it can, considering the hidden enemies and mutated zombies, An Kai must also put down a mine in the shelter for iron ore mining.

The mining target was set on the control surface, the probe was drilled into the ground, and it didn't take long to find the iron ore needed by Ankai. It's just different from the aluminum ore found before. The iron ore found this time has much smaller reserves and is not a large complete vein. It is intermittent and has many faults. This is why the mine used to search for aluminum when it was automatically searched. Ore instead of iron ore. But these are not important anymore. It is the most important to find and smoothly mine iron ore.

As the mine began to operate, blocks of iron-containing stones were sent to the shelter by transportation pipelines.
