Superman, Man of Steel, Female, 6 Years Old!

Anyway, she doesn't want to build a five-star hotel in space or a luxury flagship store, and when the farm is planted and maintained, future humans will not live in it.

Therefore, when it comes to anti-rust and anti-corrosion, it is to spray a layer of graphene anti-rust coating on the outermost layer of ordinary steel and it is done.

Yes, Anna's solution is to cover the outer layers of ordinary steel and alloys with a layer of graphene to prevent them from rusting and corroding.

Even on the shell of the space farm, which does not have to worry about rust, she will be covered with a layer of graphene to increase its strength.

You must know that as a universal nano-level material, after spraying a layer of graphene on the surface of the steel, in addition to increasing its strength, it can achieve the point where the steel will not rust when it is placed in salt water for a month .

And the raw material of graphene is very cheap for Anna, so it goes without saying how to deal with the rust and metal corrosion problems on the farm in the end.

The difficulty here is actually the problem of large-scale manufacturing of graphene that has stumped scientists.

And Anna wants to use graphene to spray the inner wall and the inner frame of the space farm, so the quantity she needs in the future will not be a small number.

However, after the breakthrough of Anna's nano-robot technology, this problem had the best solution in an instant.

When making the artificial diamond quantum core, Anna's machine can allow Kang Nachan and herself to produce 100 billion nano-robots every 687 seconds for atomic-level production.

Then after so many days.

In the super machine that only Anna can use, the parts with an internal temperature of 1 million degrees were removed, and the extremely high-pressure components with millions of atmospheres were removed.

After only retaining the function of atomic manipulation, and adding the interface of the quantum computing core and the printing program of the specially customized nanorobot.

The latest version of Anna's production equipment, which is specially used to make graphene single-layer printing, has just been released.

Because this machine does not need to control the dangerous high temperature of 1 million degrees, nor does it have the super high pressure used to artificially generate diamonds, so the use limit of this machine that is only used to produce graphene is very low.

If it is connected to the quantum core, then Caichuan, Kang Nachan, and Thor can all operate this machine very conveniently.

If the quantum computer for ordinary people is connected externally, although the operation is very complicated and the efficiency is not very high, after the software is gradually improved, even ordinary people like Kobayashi and Takitani People can also use it.

And the software program that specifically lets the machine produce graphene...

Naturally, when the task was released on the cloud platform long ago, it was one of the first batch of software and algorithms that were overcome by programmers to complete the task.

Not to mention, Anna is now on this machine, in addition to the quantum core made of diamonds, she has also installed an artificial intelligence diamond core.

So this latest version of the machine for producing single-layer graphene can now even do unmanned automated production like those machines and trucks in the mine.

As long as the supply of raw materials and energy is sufficient, it can continuously produce the graphene needed by Anna and the others.

Chapter 330 Chapter 328 Metal Smelting Factory ([-])

Although Anna's machine can only produce a single product of single-layer graphene.

But this machine is supported by the internal quantum core, artificial intelligence core, and nano-robots on the production line, its production capacity per minute...

It has also reached the point of 1000 square meters per minute for graphene products arranged with a single layer of carbon atoms.

Taking Anna’s regular hexagonal barrel-shaped space farm with a side length of 400 meters and a length of 1000 meters as an example, it would take more than 90 hours for such a machine to produce and cover the entire farm. The single-layer graphene material of the outer wall comes out.

But of course things don't work that way.

The thickness of each layer of graphene is only 0.335 nanometers. One or two layers of anti-rust and anti-corrosion are enough, but when increasing the strength, Anna will not just cover the steel shell with one or two layers and finish the job up.

At the very least, she has to spray 1mm-thick graphene on the shell, that is to say, it has to reach the legendary level of letting an elephant stand on a pencil and dance on it without breaking it. .

The graphene with a thickness of 1 mm is converted to the number of graphene with nearly 300 million layers.

Moreover, graphene, as a universal material that has entered the nanometer level, does not only have these two functions.

Therefore, Anna's latest version of the machine used to produce single-layer graphene will naturally not only have one or two such machines.

Basically just this one, in the smelter next to the mine for space farms, Anna prepared thousands of these machines and transported them through the space gate.

Moreover, the thousand machines are only limited by the insufficient output of Anna's current nanorobots, and the shortage of some customized high-precision parts is only this amount.

Of course, there is also Anna who still dislikes that the output of this first version of the machine is not high enough, so she only made a thousand units experimentally.

Otherwise, it can be understood by simple mathematical calculations. It takes 90 hours for one machine of hers to cover the entire farm, so the graphene produced by a thousand machines needs 324 hours to cover the entire farm. seconds of time.

This looks like it's going to be fast...

But to know the amount of graphene Anna needs, it needs to cover the entire farm more than 300 million times.

If only such a thousand machines are used for production, it will take more than 30 years to wait.

So one thousand graphene production machines with this production capacity...

For Anna's needs, it can really only be used for experiments and the application of single-layer graphene materials.

Wanting a graphene shell with a thickness of one millimeter, it would be hell if she really only used a thousand machines with this production capacity.

So just after these machines were finalized, Anna immediately started manufacturing a new generation of graphene production machines.

And when the ultra-high-purity graphite ore powder and the thousand machines are transported to the smelter next to the mine through the space gate, it also represents the shell metal plate of Anna's first space farm. , going offline soon.

And when the first space farm began to be built in Earth's synchronous orbit, it was time for Anna to leave.

Of course, it is impossible to install the 300 million layers of graphene right now.

Before her new machine came out, except for a two-piece shell metal plate used for experiments that could reach 300 million layers, Anna's graphene coating would only hover at the level of ten or eight layers elsewhere.

……

……

The production capacity of the iron ore that Anna obtained the free mining license is similar to that of the Seshen Iron Mine in South Africa. After she uses the smart mine and artificial intelligence, in addition to the maintenance of the Ark reactor, there are also replacement parts for machines and mine trucks.

Anna's current mine can process about 67 tons of raw ore every day.

In this super open-pit iron mine about 15 kilometers long and 5 kilometers wide, after Anna probed with the quantum perspective, there are stored about 20 billion tons of iron ore that can be mined with her current technology.

Based on the average grade of the ore here reaching 60%, if this mine is mined, then Anna can create about 48 giant space farms.

Of course, if the production capacity is not increased, it will be more than 8 years before the mining is completed.And this 20 billion tons of reserves is also for Anna herself.

For companies like Rio Tinto and Vale, their technology can only detect about 12 billion tons of reserves in the mine.

And with their ability, they can only mine about 12 million tons of iron ore out of the 6 billion tons.If they dig deeper into the ground, these companies will face various problems such as losing money and increasing the difficulty of mining exponentially.

Moreover, the transportation of this mine is very inconvenient.

Even if you want to build a railway, under the complicated geographical conditions along the way, with the current mining technology, the construction cost of the railway, and the current iron ore price...

It is impossible for ordinary mining giants to recover their costs within ten years.

Such a feeble cost and economic benefits are naturally the main reason why Anna can get the free mining rights here so easily.

However, after Anna's mine went online, she didn't have any transportation problems, nor the difficulty of mining, nor the salary and security issues of various experts and workers, so such a large place, naturally, she could do whatever she wanted.

So when the first iron ore cart was delivered.

Anna has already started her cheating metal smelting factory next to the mine.

This smelting plant does not have a blast furnace for steelmaking, nor does it have the workshops of various traditional steel companies and the pipelines for transporting oxygen and cooling water.

All ore smelting, as well as the final shaping and quenching work, are carried out in a super large quantum furnace.

It is similar to those scrapped cars and quantum furnaces that Anna used to smelt in the magic building.

However, the super furnace in this smelter is larger in size, stronger in firepower, more violent in operation, and has the most other added functions.

The most basic expression is the super huge furnace that Anna installed in the valley. Its volume has reached as much as 1.2 cubic meters, fully twice the size of the largest blast furnace in the world today.

Moreover, the ability to smelt iron ore has also reached an astonishing level of more than 60 tons per day.This efficiency is directly more than 6000 times that of the super iron-making blast furnaces of about 46 cubic meters in human countries.

Chapter 331 Chapter 329 Metal Smelting Factory ([-]) Quantum Furnace

Unlike those blast furnaces that still use oxygen top blowing and coke to smelt iron, Anna's quantum furnace is equipped with the core of a quantum computer, tens of thousands of artificial intelligence cores, and the largest scale Anna has ever carved in the blast furnace. , also after complex quantum channels and various quantum models.

When this blast furnace was smelting iron ore.

No coke reduction, no gas and oxygen smelting.

There is also no need to use the electricity used to auxiliary power the Ark reactor, which is used to supply the quantum computer and artificial intelligence core.

When this Anna's furnace smelts steel, it directly separates carbon dioxide gas from the air, and obtains carbon atoms mixed into the steel from the separated carbon dioxide.

After the ratio is determined, molten steel can be shipped directly from the furnace after putting in a single iron ore, not even the molten pig iron in the iron-smelting blast furnaces of those iron and steel enterprises.

Moreover, this smelting process of producing pure molten steel is even like those blast furnaces, which can continuously produce steel for 24 hours.

In the furnace, under the energy bombardment of the super quantum channel and other concentrated energy arrays, it can even reach a temperature of hundreds of thousands of degrees.

After the iron ore is sent into the furnace, all the iron ore can be smashed under the intense energy bombardment in an instant, and can be gasified under this high temperature in an instant.

Just a few alchemy magic circles that Anna learned from the magic book can remove the oxygen atoms and other impurities in the gasified iron ore gas like a sieve.

Then, just add carbon atoms separated from carbon dioxide into these pure gaseous irons, and finally use the magic of the quantum model to conduct heat conduction and lower the temperature, and transfer the heat in the gaseous iron through the quantum model of the furnace for recycling...

Then the brand-new hot molten steel 'cooled' from the gaseous state can be discharged from the discharge port below the furnace.

The entire process from the ore to the furnace doesn't even take two minutes.

This speed of 'magic refining', where everything is completed in an instant, is also the solid basis for Anna's super furnace to process all the iron ore in the entire mine in one day.

And this giant melting pot like a hill.

It is also Anna's most satisfying and successful quantum or magical machine in this world besides the quantum computer.

……

In fact, like all those mines, the iron ore mined from the ore bed does not mean... once dug out, it can be thrown into the furnace to make steel.

In any case, it contains impurities such as soil and stones.

However, the removal of impurities after mining, as well as the steps of beneficiation and washing, are all completed in a super large ore pretreatment center next to the mine.

All the machines inside are also a new combination of sensors and artificial intelligence cores.

Of course, these equipment and machines are not cheap. Most of Anna’s one billion dollars was spent on the mine and the ore preprocessing center, and one or two of the things in it are dozens or even hundreds of tons. heavy guy.

However, it is also because Anna does not need those manufacturers to provide three-guarantee service and transportation, so Anna can only spend so much money, and can also purchase a lot of peripheral parts for the super furnace that did not cost her much.

Therefore, when the mined iron ore is transported into the furnace, it is already pre-processed iron ore with a grade of about 64%, just like other steelmaking plants.

And below the molten steel outlet, she also set up a hot-rolled assembly line specially used to process steel.
