Chapter 98： The birth of carbon steel sword embryo

On the first day, Cravason hit the iron mound ten times, and the sheer repetition made him feel very boring. By the next day, this kind of boring and boring will continue.

It's almost time for Hanukkah. What new tricks will this year's festival have?

If a dagger is made before the festival that can satisfy the gold lord Rurik, I must be satisfied with Otto, the leader.

The next day, Rurik was still soaking in the blacksmith's shop. He was supervising the blacksmith's work and chatting about daily life in order to dispel boredom.

If there is anything that makes the two blacksmiths fresh, it is the use of soap bought for two silver coins after finishing a day's work.

The hands are full of **** and toner, and the crevices of the nails are full of ashes. With his huge beard and hair that was swollen by the heat of the flame, Clavasson has always felt that the work of a blacksmith can turn people into a large pile of bacon, which will always exude the smell of charcoal char.

The use of 　　 soap changed everything.

The blacksmith shoveled snow from a pottery urn at will. The urn was roasted on the fire, and they washed themselves with clean hot water.

The wooden door was closed, and the pottery urn was full of hot water. It is easy to get more hot water.

"Today's work is really a tiring thing, but fortunately your soap can save us." Clavasson looked away while taking off his linen lining. At the same time, the young Kawei was also doing this kind of thing.

Lurik understood at once that they weren’t simply washing hands and hair, but taking a bath.

Their performance did not make Rurik feel abrupt and weird, and then their performance made him even more strange.

Klavasen used iron tongs to cover the stove lid made of iron pans, and when it was heated, he poured water on it. The cold water immediately turned into a large amount of steam, and in a short while, the dry blacksmith shop became a closed steam bath.

The whole room was shrouded in hot and humid mist.

Lurik barely saw that the two guys were already wiping their bodies with a damp linen cloth, and Kawei was also unwittingly holding the soap on his skin.

In the absence of a shower, this method of boiled water to wipe the body is probably the cheapest cleaning method, that is, they even make the house damp by the way, so they want to come to a sauna.

But this is not a sauna, it's just Cravason's method of trying to make the supplies warmer. As for the steam to get dry clothes wet, don’t worry, after the shower is over, the wooden door and the closed chimney will be opened, and the room will soon be dry again.

They all cleaned themselves, and Rurik did so by the way.

In different time and space, wipe the whole body with soap and then wash it off with hot water.

"Ah! At least this will give a sense of modern life..."

or took a shower, Rurik fell asleep this night.

Life is generally quiet and slow. In the cold night, those guys who deliberately go elsewhere to plunder and enrich their money box, they also have to die.

Adults stay in a warm home and wait boredly for the snow to melt, while children spend almost all their childhood in boredom.

The feeling of boredom has always been with Rurik, and he consciously has to do something. I used to be too young to do anything when I was five or six years old.

According to tradition, in the new spring, you can claim that you are eight years old, and this Nordic body is growing significantly faster. As height and strength enter a period of rapid growth, people's subjective initiative also needs to be improved.

It is a useful start to teach blacksmiths more advanced iron smelting technology than their counterparts in time and space. Later, in the research and development and production of weapons, they will inevitably have greater achievements.

So, can a short sword with a medium carbon steel blade and a high carbon steel blade succeed? It depends on the in-depth processing in the next few days.

After a comfortable bath, the soap took away the mud and smoky smell of the two blacksmiths, which seemed to take away their tiredness. Starting

On a new day, with a hundred points of energy, Cravason and Kawei began to repeat the work of the previous two days.

is repeated ten times a day, and each cycle has been calcined as a critical point.

Actually, the iron bar is wrapped in plant ash and carbon powder and burned, and the infiltration efficiency of carbon molecules is still relatively poor. Compared with the carburizing method for manufacturing alloy steel, it is not as efficient as the carbon loss method. That is the limit temperature of charcoal combustion in the blast furnace, which produces a large amount of liquid pig iron, and then uses some methods to make the pig iron lose carbon. Only this method can produce carbon steel more efficiently, and there is no need for "50 refines" and "100 refines." "The craftsmanship of the exhausted blacksmith.

As long as the money is enough, Kravasson and Kawei will no longer complain.

Blacksmiths, their identities in any tribe are complicated.

The blacksmith did not believe in Odin, so he was naturally sent out of the battle by the tribal warriors. But all the production activities of the tribe require the blacksmith to build tools for them, and the tribe, especially the warriors, especially need them.

Due to the characteristics of traditional block iron making, it is most suitable to be made into an axe. One edge of the axe is a sharp weapon, and the other is a hammer. The axe blade is the key to logging, and the hammer head can smash the enemy's armor. The battle axe is really a suitable weapon, but it is too bulky.

Generally speaking, unless the warrior's axe is cracked, they will find a subway carpenter to help repair.

The so-called cultivating kindness, the situation is not much different from what Kravasson is doing now.

But the matter of cultivating goodness, others seem to be the blacksmith burning the damaged product back to its original form. It seems that as long as the fire is mastered, any strong person can easily complete it. Only for repairing goodness, Kravasson’s customers will not pay much, often only a few dozen copper coins.

Normally, after completing the repair of three axes, he can earn one silver coin, and he must also consider the charcoal loss during the repair process.

To repair the tomahawk, it was hitting against a huge iron block, compared to the one-third stika-length iron rod requested by Rick. Any hitting is not very troublesome.

If they were all tools for repairing this kind of volume, Clarvasson calculated that he would only earn a silver coin by repairing six of them. Thinking about it this way, the number of silver coins given by Rick was actually a bit more.

It was the same on the third day and the fourth day. On the fifth day, the requirement of repeated calcination and forging fifty times, which Rurik required, was getting closer, and Kravassen's mood became more and more excited.

As a professional blacksmith family in the tribe, the family members are very unprosperous. He attributed this to fate.

But my son has inherited the blacksmith's career very well. After a long time working in ironmaking, the two of them still found some skills from the boring work.

Although they did not spontaneously invent some new technologies to make iron smelting more efficient.

They have good skills in smelting bronze, and they can cast more peculiar bronzes on clay mold casting, such as those sold or given to the priest’s longhouse.

For example, bronze ware is also smelted. The amount of tin and lead content determines the color of the bronze ware. The two of them already know how to mix the weight of the raw materials to make the most suitable alloy solution, which has long been shining golden bronzes.

But in terms of iron smelting, the iron mounds made by the two are all black, it seems that iron is like this.

After the axe and sword are made, they need to be polished. It can reflect the luster of beautiful metal. For example, the iron sword is a very good silver gray, but it is not resistant to chopping, such as smashing stones several times. , The blade curled up.

Cravason has always been aware of it. He counts the number of times the iron bar is burnt and forged.

His forehead was full of sweat, and he asked excitedly, "Ruriek, it's the forty-ninth time, and our mission is about to end."

"It's almost done?!" Rurik stood up abruptly, patted the dust on the leather jacket again, "Go on. I have new requirements after fifty times."

"Well, my boy. Now this iron bar has some strange changes."

"Oh? What is that?"

"Its color has changed in the past few days." Kravasson can no longer conceal his doubts, because in decades, he has not seen the ironware he made, except that it will become red because of rust. There are other color changes for ironware. "I think the color of this iron bar becomes brighter when it cools."

The description of the color caught Rlick's nerves in an instant.

Lurik hurriedly ran to the hot stove: "Really? Let him cool down naturally and let me see the color change."

The folded and forged iron mounds turned back into iron bars. The open wooden door allowed the air to flow in from the outdoors, and the room became cold, except that the stove was still hot.

Under the action of the cold wind, the color of the iron bar that has gone through forty-nine forging has really changed!

It was completely cooled, and it was held by Clavasson. As long as it was compared with the iron tongs made of wrought iron, it was obvious that the color difference between the two could be found.

is like sunlight shining on the iron bar of the 49th refinery, its color is obviously brighter, and it is also like adding a little white dye to make the iron bar white.

Is it really added? of course! That's carbon!

Lurik was happy as if he had eaten honey. He stomped and yelled desperately. The joyous celebration did not mean that the five-day battle of the blacksmiths was not in vain.

"Are we successful now?" Kravasson held down Rurik excitedly.

"Yes! Basically succeeded. After doing the last time, apply grease to stick ashes and carbon powder, and then calcinate it for the last time. After that, it will be cooled naturally, and it will be shaped like a sword."

Finally the stage of making a sword embryo is about to come, and Klavasen takes it for granted that this is Rurik's last request.

It seems that as long as you work hard tonight, the sword that Rurik wants will be at its final stage.

The last calcination was completed in the eager expectation of the blacksmith, and the bucket of water finally leaked clean. Cravason couldn't wait to use the tongs to take out the red iron bars. Can it still be called an iron bar now? No, at least it is also a low-carbon steel bar!

Cravason did not discount it in half, but instead worked with his son Kawei to strike while the iron was hot.

The shape of the dagger is really good for the two of them to beat the iron bar into the shape of the short sword, and according to the traditional tradition, the shape of the sword is not the same as that of Rurik.

Swords made of wrought iron are not suitable for chopping. Indeed, the invention of the sword is to lengthen the spear as much as possible. From the beginning, the sword's method of killing was mainly stab.

The Wrought Iron Sword inherited this tradition, so that the Kravasson father and son, on the one hand, had to knock the sword into a shape with a middle back, and it also had a terrifying sharp-angled blade to achieve the best thrust effect at a time.

In the past, iron swords were made in this way, but Kravasson used this method. Is it also suitable for steel sword processing?

The shape of the dagger satisfied Rurik. Look at that sharp blade, even if it is not sharpened, it is a very dangerous existence.

After a lot of vigorous beating, coupled with countless fine chiseling, the dagger became more and more beautiful.

"As long as it is quenched for the last time, it should be done. As long as we are sharpening it, we can try to see if it can cut the iron block." Kravasson said, and asked his son Kawei to turn out the whetstone. .

Lurik stopped Kawei immediately, and said, "There is still very important work that has not been done!"

"Huh? There's more?" Caravason asked.

"The sword will remain like this for the time being, blacksmith, go make some mud."

"Okay... okay."

Cravason doesn’t know what this kid wants mud for. He never lacks clay mud here, because all his stoves actually take a long time to repair. Those slags from iron smelting are actually some disaster materials. So the furnace must be repaired every once in a while, and the repair material is clay.

Some mud has been made, but in fact it can’t be called mud, it is more appropriate to call it mud.

Here, Rurik personally knead the mud into sticks, sticking the mud to the back of the sword on both sides, and only the place where the blade is prepared to be cut is exposed after being flattened.

"Rurik, you...what are you doing?" Kravasson asked inexplicably.

"Of course it is covering the soil and calcining the blade. Believe me, doing so will make the blade the hardest thing in the world." Rurik said on purpose, but in this era, humans seem to be unable to make higher carbon A practical tool for harder steel.

He went on to say: "You put grease on the blade of it, stick wood ash and charcoal, and continue to burn it with firepower. But this time we will burn it for a long time."

"about how long?"

"This..." Rurik didn't have a spectrum in his heart, he said of course: "Five buckets of water. When the five buckets of water are all drained, we will take out the sword again, and we will quench it directly."

How long does it take for a bucket of water to flow from the small hole? Rurik felt that it was not a short time.

In fact, it must flow out for more than ten minutes. The "five buckets of water" that Liu Rick said when he patted his thigh was barely more than an hour.

Karavasan is not nonsense, he put the sword into the carbon pile again, and began to really cover the earth and burn the blade.

Until now, Rurik still didn't tell the blacksmith about a series of incredible processing methods he requested, and what kind of principle is behind it.

Even if Kravasson has been asking now, is it possible to burn an iron sword with a piece of ceramics?

Indeed, as long as more time, any shape of clay can be fired into pottery flakes. The processing method of pottery is very simple. As long as there is enough clay, mass production of pottery is possible.

"The time of five buckets of water" finally passed through people's anxiety, and Kravasson couldn't wait to take out the sword with two pottery plates attached.ァ新ヤ~⑧~1~中文网ωωω.χ~⒏~1zщ.còм

The attachment of the pottery peeled off as soon as he left the fire, and Kravasson looked at the blade of the sword held by the tongs thoughtfully.

Lurik hurriedly urged: "Quick quenching! Use snow water directly this time! Quick."

did not use oil quenching, this time it was directly water quenching. The temperature of the iron rod burned to six hundred degrees dropped sharply, and the effort in a few seconds dropped sharply to the level of human touch.

Now Klavasen realized that the embryo of the sword he was holding in his hand was really incredible. Because its whole body is still bright and white, and there are many small irregularities on it that need to be polished, but it can't hide its unique color.

The most amazing thing is the preparation of the edge, these areas are the brightest, as if the back is not a material at all.

Unlike Clavason and Kawei, Rurik is only happy here.

"Haha! I made it!"

"Children? We really made it?!"

"Of course. Blacksmith, thank you for doing it now. I am very happy, you helped me to sharpen it, and you try to sharpen it as much as possible. For this, I will pay you two more silver coins now."

"Oh? There is still money?" Karavassen was pleased to be further generous.

"Of course! But I have to tell you that this sword is completely different from the one you made before, and its sharpening may be a more laborious process. But your hard work will bring good results."

"You mean that as long as you use a sharp blade, you can cut off the iron sword in my warehouse?!" Crava asked.

"Of course! I will always be with you. When my sword cuts off your ordinary iron swords, I will tell you the principle of everything. From then on, you can make swords."

At this moment, Kravasson felt that the iron-strike technique he had learned from his dead father was weak. If all came true, he would not kneel down and face "Odin the Blesser" Rurik and thank him. Granted "advanced iron technology from Valhalla".
