Chapter 248： From the melting pot! Warship steel! (2/2)
The discharging area, like an oil well, is also connected by four thick pipes, connected to four square iron boxes on the ground. The space of each iron box is 15 cubic meters, and it is on the rightmost square box. On the side, there is another pipeline that leads directly to the feeding area to ensure that the things that need to be smelted can be recycled repeatedly.
”Yes, yes, although there are mysterious technology elements in it, so far, the working principle is still easy to understand!”
Stroking the surface of the furnace made of unknown materials, with Somo's appreciation, the attribute map of the furnace also jumped out.
【Melting Furnace (Excellent)】
[Description]: Modular technology products have a series of wonderful ways to use them. When combined with other modules, they have incredible magical effects.
[Currently owned modules]: Crucible module, strong reaction module, storage module
【Function】: Processing
[Power consumption]: 10kw.h
The current furnace has only three modules, corresponding to specific functions, it only has the attribute of smelting.
After trying to cut out the system panel and seeing that adding other modules would require tens of thousands of points at every turn, Somo quickly dismissed the idea of upgrading.
”There is only one processing attribute, which is completely enough for use at this stage”
”As for the functions needed in the follow-up, it is not anxious. You can collect them slowly and see if you can get them out of the box!”
When the furnace is activated, it consumes enough electricity for one hour.
Try to connect the stout connector to the stoutest wire interface reserved at the beginning of the shelter design.
As Somo returned to the second floor and turned on the diesel generator to supply power, after turning on the power to the furnace, the furnace began to blast for the first time.
Snapped!
On the side of the feeding area, there are also palm-sized electronic screens that are as familiar as oil wells popped up, showing what can be manufactured in the only processing functions currently available.
”The most needed thing at the moment is definitely the steel plate used to make the destroyer. If this thing is not built well, I am afraid that it will fall apart after two steps!”
”But since it is to be made, at least it must be guaranteed that there will be no problems for three to five years, and the materials are selected!”
There are many bells and whistles on the panel. After some screening, Somo quickly found the steel column and clicked on it.
Common steel can be divided into ”structural steel” and ”tool steel” according to its purpose.
According to the alloying elements, it is divided into ”carbon structural steel” and ”alloy structural steel”.
It is also divided into ”carbon tool steel” and ”alloy tool steel”.
According to the content of S and P impurities, it can be divided into ordinary steel, high-quality steel, high-quality steel, and super high-quality steel.
At that time, the famous Titanic, which was known as never sinking, fell silent after hitting the iceberg. The reason is that the steel plate used contains many chemical impurities zinc sulfide, and long-term immersion in cold sea water makes the steel plate more fragile. .
Only after a small impact, it broke apart and became a permanent regret.
Therefore, in the selection of materials for the destroyer, based on the principle of high to low, Somo directly skipped the low-strength steel and focused on the military steel used to make ships.
The application research of military steel is very cumbersome, and there are more than 140 in nine categories.
Accurate tests must be made on the strength, toughness, crack resistance, stress state at low temperature, etc. of the steel.
Under normal circumstances, like the materials used for aircraft carriers, the yield strength of deck steel should be 90+0Mpa, and the yield strength of ship hull should also be 780Mpa.
Continuing down, the smallest destroyer must be maintained at a strength of at least 400Mpa to ensure maximum safety.
”At present, the best steel that can be manufactured by the furnace is only 620Mpa strength, which should be subject to the temperature that the supporting facilities of the shelter can provide.”
”Or it has something to do with other modules!”
Arranged from high to low, the yield of the best military steel is not low, but after clicking in to check the specific requirements, Somo directly gave up the idea of manufacturing.
Without him, resource consumption is too terrifying!
Military steel needs to add a lot of weird things, in the furnace, this step is simplified to only need to provide a sufficient number of basic materials can be achieved.
But for the quantity of this basic material, after checking that a unit of 620-strength steel actually requires 1380 units of iron and 880 units of copper, Somo can only slap his tongue and choose to give up.
There is nothing wrong with modern warships using such expensive steel, because the hull steel plates of modern warships are actually not thick, on the contrary, they are very thin. For example, 052, the thickness of the steel plate is only 30 mm.
What concept? The thickness of a one-dollar coin is 25 mm, and the steel plate of a warship is only 5 mm thick.
In modern warfare, the methods of attacking warships have become more and more advanced, from the original bomb torpedoes together into the popular anti-ship missiles, and the silent hunting of nuclear submarines equipped with large-caliber torpedoes.
In this case, too thick armor will not only not provide protection, but will only slow down combat performance.
But on the wasteland, to design such a thin armor according to modern thinking, and fight a modern war, it is simply to die.
Not to mention anything else, if there is a foreign race in the water by then, you can easily dig out a big hole with a steel fork.
”The steel plate must be thick. There is no weapon equipped with a destroyer. Thickness is justice. Even if it hits, I have to hit it!”
At present, there are only about 8,000 iron blocks in the refuge, even if it is temporarily mined, this number will not exceed 30,000.
Calculated on the basis of the destroyer’s length of 40 meters, the required steel, according to Suma’s design, would require at least 2,000 units to start.
Under this demand, if the unit price is controlled at about 10 to 1, the best price/performance ratio is.
580? Too expensive~~ Give up!
520? Still too expensive, give up!
Picking all the way, watching the intensity getting lower and lower, and even when he was about to break through the psychological limit, it was not until the demand for 440-strength steel jumped out that Somo let go.
440Mpa military steel, 1 unit requires 13 units of iron and 1.5 units of copper.
2000 units, you need 26000 units of iron and 3000 units of copper!
With the current reserves in the base, 18,000 units of iron must be mined to meet manufacturing needs.
”The plan does not conflict. If you want to survive the next disaster, the people in the Candlelight Refuge must relocate to Iron Mountain!”
”With excellent quality iron picks and storage space for transportation, hundreds of people are not slower than machinery, or even faster!”
”You can kill two birds with one stone. While mining enough iron, you can directly dig out a large space enough for hundreds of people to survive the disaster!”
