Since Renault became the lord of the Tide Islands, a series of crises in the territory, such as food crisis, energy crisis, housing crisis, etc., have been solved by him one by one, but one crisis has never been resolved.

Instead of getting it done, it is getting worse.

It is, steel!

Weapons require steel, machine tools require steel, and construction machinery also requires steel. The latest thermal engine developed by the Rune Research Institute is a big consumer of steel.

The entire engine is a huge metal tuft weighing several tons, plus gearboxes, propellers, and drive shafts. A single system will consume more than 10 tons of steel.

Therefore, the territory's steel is in a hurry.

Some time ago, in order to manufacture the Odin's power system, not only the iron ore stored in it was used up, but Renault even melted away some less important metal products. As a result, the steel was still not enough.

Just when Renault was planning to organize manpower to venture out to sea, after Miss Consul asked about the gap in steel, she patted her chest and said, "Give it to me!"

Then the consul convened all the civil servants and held a short meeting to mobilize everyone to purchase metal products from the leaders.

When the civil servants visited the civilians from house to house and sincerely stated the current difficulties in the territory, the civilians generously donated their money, and many even donated the pots for eating at home.

When the civil servants refused to laugh or cry again and again, the civilians said very generously: It's okay! We can share a pot for several families.

In just one day, the Government Affairs Department purchased nearly 20 tons of steel through this ant moving method.

This surprised Renault.

The consul Miss looked indifferent. She also said that if she was given one more day, the Office of State Affairs could obtain more steel, and conservatively estimated that it could exceed 40 tons!

As the chief administrative officer, the girl deals with civilians almost every day. She deeply understands how high the prestige of today's lord and the government affairs office is in the hearts of the leaders.

Let everyone eat meat to their fullest, spare no effort in disaster relief, help the civilians repair damaged houses, and even build wooden houses for the victims. This matter has already brushed Renault’s reputation among the civilians to worship. !

So when the civil servants came to ask for help for an unprecedented time, the civilians responded enthusiastically.

And the birth of the first Heat Demon engine can be described with the words "smashing the pot and selling iron", which is not an exaggeration.

After the Odin completed the final modification, Lord Lord didn't even plan to do the test, so he took his men and horses straight to the Ironclad Island.

Because there is a rare open-pit iron mine on the island!

To be precise, over 95% of this Tiejia Island with a total area of ​​more than 35 square kilometers is open-pit iron ore.

Picking up a few stones on the island are all high-grade iron ore with an iron content of more than 65%.

Not only that, it is said that someone once went into the water for simple exploration, and there is a huge vein that extends for tens of kilometers under the water.

No one is going to explore further away, because there is no need. The iron ore already on the island has been used for many, many years. Even if it is explored in other places, it will not be mined. Why do you bother?

Isn't this enough to support you?

It can be said unceremoniously that Iron Armor Island is an out-and-out island of iron ore!

How many iron ore reserves are on the island?

Renault has not done a detailed survey, but according to the existing data, the reserves are extremely...extremely...amazing.

The iron ore on Tiejia Island alone is astonishing tens of billions of tons!

at least!

According to the calculation of taste, more than 7 billion tons of steel can be extracted!

When Renault came to this conclusion, he couldn't help but feel extremely grateful for his choice of "farming in the Tide Islands", and even more grateful that he did not give up when his life and death were uncertain in Elon, but insisted on searching.

Just this super iron ore, which is enough to last for a hundred years, is worth all the fares.

The magic dinghy full of island guards had just rushed to a black sand beach, Moose screamed again and again, urging the players to disembark as soon as possible.

Then he issued a series of orders, arranging some people to build fortifications, and the other part, led by Ronald, responsible for guarding, and the beach immediately became busy.

Ronald was obviously a little nervous, because there was a very difficult big guy on the island. Compared with the black iguana on the black lizard island, this creature was more restrained from magical air guns.

At his request, the guards all took up the magic air rifle in their hands and were ready to fire at any time.

Not long after, Renault landed on the beach leisurely. Seeing that the color of the beach was so strange, he couldn't help but squat down and grab a handful of gravel to observe carefully.

These gravels are larger than ordinary gravels, and the surface is slightly rough, and it seems that the tide is difficult to round them.

In addition, the heavier weight than ordinary gravel fully shows that they are actually gravel-like iron ore.

It is indeed an island of iron ore, and there is a beach entirely made of iron ore. The other world is really a world full of miracles.

The black gravel indicates that they are black iron ore with higher iron content, that is, Fe3o4.

On the earth, black iron ore is almost all magnetite, and without exception, they have strong magnetism, but in another world, strange things happen, magnetite actually loses its magnetism!

Not only that, Renault has never heard of magnets, and people in other worlds don't even know what "magnetism" is.

Although I don't understand the reason for this, it is obvious that this is the mana's hands and feet, and the magnetite in the alien world has been demagnetized.

This also caused a huge trouble for Renault: electricity, no more!

The magnets are gone, what else can be used to generate electricity?

Is it to use love to generate electricity?

At the same time, all the science and technology trees related to electric energy can't grow out.

When Renault first learned of the terrible fact that "there is no magnet in another world", he was sad for a long time.

Probably among the traversing army on the earth, Renault is also considered the most unlucky group.

A world without electricity is really sad.

Because the computer is gone...

Mobile phone, no more...

*****, there will be no more...

Well, unless you play it yourself.

Even worse than him are the traversers of liberal arts students, because even if they have electricity, they can't send it out, hahaha...

Unless there are non-scientific means.

Power generation is not as simple as imagined. I really thought that you could get electricity by getting a bunch of magnets to create a magnetic field, then taking a copper wire and cutting the magnetic field for fun?

Extremely naive!

This is just the way to play in the laboratory. At most, you can light up a low-quality light bulb to see the wonder, tease the strange world to relieve boredom, and it is still a thousand miles away from large-scale practical use.

The principle of power generation is very simple, which is correct, but in the end, everything has to fall on the mechanical equipment. To build a reliable power generation equipment, you need to light up the huge front-end technology tree.

As a mechanical dog majoring in thermal energy and power engineering, Renault has taken courses in thermal power generation and visited large thermal power plants. He knows how difficult it is to build a large thermal power plant.

A single large steam turbine represents hundreds of years of technology accumulation behind it.

Thermal power is really difficult, but what about hydropower?

The core equipment of hydroelectric power generation is a hydroelectric generator. Its structure is simpler than that of a steam turbine, but it is not easily manufactured by anyone.

Not to mention blades, which have extremely high requirements on materials and processes, a cast iron shell alone is not simple.

Isn't casting just pouring liquid metal into a cavity? How difficult can it be?

Is it really?

of course not!

Casting is far more complicated than most people think. The difficulty of casting large and complex parts is not small at all.

Take sand casting as an example. It is not possible to make sand for sand casting. In order to ensure the formability, the sand must be added with a special binder.

With sand and binder, what kind of sand mold can I make?

of course not!

Making sand molds is a rigorous craft. If you don’t play with sand for several years, I can guarantee that you won’t be able to squeeze the simplest sand molds, and you don’t even want to look at the things you cast.

The design of the sand mold is also very particular.

When the casting is poured, the molten metal flows into the cavity from the pouring port, and the gas escapes from the special exhaust port.

It looks simple right?

Is it really that simple?

of course not!

If the structure of the cavity is complicated, can you ensure that all the gas can be discharged in time?

Once there is any residual gas, after the molten metal cools, defects such as "shrinkage holes and blisters" will be formed on the surface of the casting.

In other words, what you put out is not a casting, but a sieve disguised as a casting.

Do you know what a sieve is?

It is the sieve in "the sea, you are all water; the sieve, you are all holes"!

Therefore, the location of the exhaust port is very important.

The flow and cooling of the melt in the cavity also require special attention.

Uneven flow, over!

Shrinkage holes and blisters are coming again.

Uneven cooling, over!

Let me tell you, this time there are cracks inside. What you have made is not a casting, it is a bomb, you know?

Therefore, the location of the pouring port is also very important.

Having said that, do you still think that casting is to pour molten liquid into the sand for fun?

The generations of mechanical dogs on the earth, although all of them are stubborn, dull eyes, and boring in speech, whether it is economic or social status, they are in the middle and lower levels of the chain of contempt, but the wisdom of this "canine creature" , Definitely not to be underestimated.

If Renault hadn't had the God-level manufacturing ability of [Nian Motive Force], he could surpass all the manufacturing problems unreasonably. He would have been hiding in a corner that no one could find, sitting and watching Yunjuanyunshu.

Well, by the way, I have children with Angela and raise pigs.

You can also ask Moose to help with the children, and you have to find something to do for the retired elderly, right?

Even less dare to boast about going to Haikou, saying "shits" like saving all mankind and killing the black orcs.
