Rise of Rurik

　　Lurik never thought that Kravasson had been using high-quality magnetite.

　　 He immediately asked with excitement, "Could it be...there are these iron ore in the mountains west of our Roseburg?"

　　 "Of course, is it weird?" Kravasson replied indifferently.

　　 "Isn't it weird? This is the best ore! The best iron ore in our world."

　　 When the child said such words, he was boasting that the bitter cold place of Roseburg was actually full of treasures. At least for the blacksmith, establishing an iron-making workshop near the veins can indeed bring him a steady stream of wealth.

The Ross tribe moved north to the Roseburg Fjord, seized this area from the Sami, and developed. One reason is that the land of Svealand has become narrower due to the increasing population of people, leaving it somewhere. New geographical development is an acceptable choice. In fact, quite a few tribes and small families have been doing this.

　　 The second reason is to look for fur resources in the north.

　　 But the people of the tribe didn’t know that their northward pioneering not only expanded their knowledge of the world, but the blacksmiths discovered directly exposed iron ore in the mountains.

The blacksmiths don’t understand the iron content and taste of the ore. The few blacksmiths of their tribe are just very happy that the ore is relatively easy to get, so they can build more axes, iron swords, and iron pots. , Iron fist, and iron nails that are very much needed for shipbuilding.

　　 Besides, there are not only a large amount of iron ore but also a small amount of copper ore in the mountainous area.

For the Cravason and his sons, it was very easy for them to find iron ore because they did not know that the fjord where Roseburg was located was the remnant vein of a huge iron ore vein. Although it was a remnant vein, the iron content of the ore was also More than 60%.

　　In the future, Sweden found the main ore vein in this area, and obtained ore with an iron content of up to 70%. It is almost a pure magnet and contains no impurities.

　　Because, located in the northernmost mountainous area of ​​the Gulf of Bothnia, this vein originated from the orogeny 1.9 billion years ago. The very ancient Finnish Craton was lifted, bringing part of the iron in the crust to the surface.

Due to this geological structure, this vein, which spreads as long as 300 kilometers, has a complicated structure when it was born, but it has not undergone more geological structural changes in the next 1.9 billion years, making it very lacking in variety. Impurities, especially it contains almost no sulfur.

　　 It contains almost no sulfur, and its body is almost a magnet. No giant iron ore of better quality has been found on the entire earth.

　　 Cravason didn't understand this at all. He didn't understand that because of these innate factors, he spent the same price but smelted more high-quality wrought iron than his counterparts in Frank. Due to the limitations of geography and vision, he had no idea that his smelting had always had a strong advantage.

　　 The iron content of the ore is extremely high, and it seems that only a little processing is a good quality stone tool.

　　 I saw Clavason threw the ore into the furnace again, and urged his son Kawei to adjust the air outlet of the blower.

Afterwards, Kravasson took a piece of hot carbon from another normally burning stove and threw it into the iron smelting furnace. Soon thick smoke appeared. Due to the heat, the smoke almost collected towards the chimney. This also shows that The phenomenon of thermosiphon is happening.

　　 The charcoal in the furnace burned, and Kawei tried his best to drive the blower. He was tired and sweaty on the cold days, and soon this young struggle was rewarded.

　　 At first, the yellow flame burst out, and the thick white smoke burst out fiercely.

　　 The color of the flame is changing, and gradually it becomes a bluish flame.

This shows what? Blue flame, when charcoal is completely burned, blue flame is produced. As a fuel, charcoal has reached the limit of heat release in a small stove.

　　Lurik understood that if Kravasson’s hands were not a small stove, but a rammed earth blast furnace of the height of a three-person stack of Arhats, a larger blower would supply the air, and the charcoal in the lowermost combustion chamber would be a white flame. Only in that state is the charcoal really reaching its exothermic limit, and the ceramicized outer layer of thick rammed earth can restrain heat loss very well.

　　Only in that extreme state, the iron ore can be directly cast by the workers in the state of the molten pig iron rich in carbon elements.

　　, it's just making a thick hoe. Casting it with pig iron is mass production.

　　 If the small furnace is made larger, since the local magnetite is very high-quality, Rurik feels that the molten iron for pig iron can be made.

　　Let’s see what else Clavasson has to do.

　　 The charcoal core in the stove is where the heat is. Facing the stove about three meters away, Lurik’s small face is also very comfortable.

　　 He paid special attention to the discharge port at the bottom of the small stove. Although the stove is crude, the workers can at least see the state of the ore in the stove.

　　 just now was a pile of magnetic black crystal shiny ores, after a long time, it has turned into red and white hot masses. What is the temperature of the ore? At least it's over a thousand degrees! The magnetic force has disappeared due to the high temperature, and the oxygen in the ore completely reacts with the carbon in the charcoal on a large scale, turning into carbon dioxide and releasing it into the air. The **** of the silicide has become a viscous liquid, it is like molten glass, and Rurik saw it with his own eyes that the **** slowly flowed out of the furnace!

　　 The outdoor sky is completely black. The iron-smelting stove in the room is even a little hot. The open wooden door allows some cold wind to enter. It is no longer cold, and Rurik actually feels comfortable and refreshing.

　　 He has been sitting for a long time, and his hunger makes himself and his servant very upset.

　　 He suddenly asked loudly, "Clarvasson, is it still okay?"

　　 "Wait, maybe you are hungry? That's okay." Clavasson immediately ordered Kawei, who added firewood, "You go and tell your mother to give the best meat to our guests. Go!"

　　 Because of tradition, women are not allowed to participate in smelting iron. Perhaps this is not a form of discrimination, but the essence is due to the contradiction between the relatively weak power of women and the huge physical consumption of iron smelting. A person with increased IQ will not require his wife or daughter to devote himself to heavy physical labor.

　　 Clavasson’s wife is also very old. She is the logistic housekeeper of the blacksmith's family, and the jerky that Liurik ate soon came from her.

　　 It seems that the jerky flavors produced by the entire tribe are the same. The blacksmith provided himself and Lumia with jerky and crude bread cubes. The flavor of the jerky was an old onion, except for a little powdered salt. First release https://https://

　　 Onion, this is something that can be planted in the short frost-free period of the geographical location of the Ross tribe. Onions are almost sugar-free, and people do not get any good benefits from growing them on a large scale. The only benefit of onions seems to be the other taste of sweetness and then spicy, which can offset the bitterness and astringency of crude sea salt.

　　 How long has the time passed?

　　 Actually, three full hours have passed since Otto went home first. The blacksmiths don't have any timers at all, they use their feelings to estimate the heat.

　　 "The time should be up!" Clavasson, who had already eaten dinner, gave an order, "Kawei, let's go. There is also Rurik, you will see our beating."

　　 Liu Likla stood up with Lumia, and couldn't help but walk back a few steps.

　　 A large pile of molten ore was pulled out by iron tongs, and the young and strong Kawei moved it to the iron platform, followed by a smash with the big hammer clenched by Kravassen's hands.

　　 A large number of sparks splashed out because of this knock, Rurik saw it really, and the molten ore immediately collapsed.

　　 "This! Is this hot forged sponge iron?!"

　　Lurik's eyes widened, he had a lot of super-age knowledge in his mind, but there were very few opportunities for practice.

　　 Cravason’s iron striker is really a father-son soldier. In the beginning, the son held the pliers to fix the sponge iron, and the father waved the hammer to beat it.

　　 The father was tired, so he changed to the son to beat him in time.

　　The larger the sponge iron quilt, the smaller it is, in fact, the loose and porous structure inside has been smashed more and more densely.

　　 It was beaten for a while and then thrown into the stove to continue heating, and then the iron was struck while it was hot.

　　 A long period of boring time passed, and the tired Rurik finally waited for the birth of an iron mound.

"What do you think now? Rurik? I specially hammered it into this shape." Clavassen looked proud, because their father and son had beaten a tuft of sponge iron into a basically angular square iron mound. . New 81 Chinese network update the fastest computer terminal: https://

　　The ore can be made into this way with the original method, and the blacksmiths' processing technology is already very good, that is, the current status of the iron mound is a large piece of wrought iron with almost no carbon.

　　 Klavasen looked flattering: "Now, boy, can you tell me what way can it turn into the hardest kind of iron?"

　　 Lurik settled down and asked, "If no one told you those methods, how would you deal with this piece of iron?"

"I will put it in the stove again, burn it red, take it out and knock it into the shape of an axe. When it is still very hot, suddenly put it in the cold snow water, the axe will become harder. But with your father His sword is still too soft."

　　Lurik nodded deeply: "Okay, I will tell you how to make it the hardest iron."

　　 "Ah! I..." The excited Clavassons hurriedly pulled their son, and the two big men sat on the leather cushions, listening to the teachings from the children.

　　 It would be great if you could learn the technique of steelmaking in a few words. Klavasson seemed to be as usual, but he suspected that Rurik was just entertaining himself.

　　 Cravason's complexion became serious, he couldn't believe it. For example, to make the iron hard, just throw the iron mound into the stove and burn it into strips. After folding, continue to beat it into strips. The cooled iron bar is not quenched at all, and continues to be thrown back into the furnace for heating, hot red and taken out to continue beating, and further beating after being folded.

　　 He widened his eyes and asked, "How is this possible? It's ridiculous. Does it mean that the iron will become harder and harder as long as you repeatedly grill and beat it?"

　　 Leave Rick's face unchanged: "Yes, it will get harder and harder. This is the only way you can achieve it now."

　　 "No way! What's the point of forging to burn? Iron is iron."

"Then, do you think that the sword my ancestors got on the battlefield was really a gift from Odin? No! It was actually some mysterious blacksmith who wielded it in a certain way. Trust me, just follow my method. , Barbecue and forging are repeated ten or fifty times. Although you will be very tired, after these work, iron is no longer ordinary iron. Its color will change, and it will become whiter, just like during the day. The color of the silver when it was cast."

　　 Ordinary iron swords, after polishing, the whole is off-white, which is essentially different from the bright white of silver.

　　 "But..."

"Do you still have doubts? Is it a matter of money?" Rurik estimated that he would dislike the exhaustion of more than ten repeated exercises, so he said: "I want a good dagger, I am willing to work hard. I am. Please follow my method. Whether you succeed or fail, I will pay you ten silver coins. These ten silver coins are just to buy your strength to strike iron. If you still need money, I will invest in it again."

　　 What can you shirk if you have money? Besides, the leader's son is really generous.

　　 Clavasson’s exhaustion was almost wiped out. He held back the doubts in his mind and followed Rurik’s requirements with all his heart.

　　In this way, a vigorous and vigorous work of beating Hundred Steelmaking has officially begun!

　　 In this blacksmith's wooden house near the beach, Rurik could not sleep for a long time because of his mental excitement, so he continued to stay in the blacksmith's workshop, guiding two equally excited workers to strike iron at any time.

　　 Lumia was led away by Clavasson's wife for the time being. They went to the long house where they stayed to rest in order to escape the sweating place of the blacksmith, but they could still hear Clavasson's constant beating in the silent night.

　　 The sound of striking iron seemed so strange, and the residents nearby were all curious. Today's blacksmith must have received a rare big order, forcing him to strike iron all the time.

　　 Yes, it is indeed a big order, for which the funder has invested nearly forty silver coins in total.

　　 The value of a silver coin is very high, and Rurik is not really that lavish~www.readwn.com~ just because the money comes too easily, it is the huge benefit brought by the short-term soap violence. He and Lumia are quite similar in this respect, neither of them is very clear about the true purchasing power of silver in this time and space.

　　 The seven-year-old Rurik is also a tragedy. The farthest place he has traveled through so many years is the hillside west of Roseburg. He has never left Roseburg, and still does not know the real situation of the outside world. Those so-called Southern allies are limited to rumors. Only those thousands of guests prove that allies are real, and that they are allies.

　　The wrought iron was put into the stove and burned red. It was beaten into strips for the first time, and it was also folded and beaten for the first time.

　　 When Clavassen was about to listen to Rurik's request to see him put back into the hot stove, Rurik suddenly stopped him.

　　 "What? Can't it be put in?"

　　 "No! The temperature of your stove is too high." Lurik stopped.

　　 "Don't you just burn it red?"

　　 "Of course not, you have to burn it barely first, and then leave it quietly outside until it cools naturally."

　　 "Why?"

　　 "Because it's called tempering!" Rurik directly uttered the word tempering, describing this processing process once, but the principle cannot be explained in a few words. He emphasized: "You just do as I said. When it cools, you go to burn it red, and then repeat folding and forging."

　　 Cravason nodded, and did what the benefactor said without saying a word. He and his son Kawei really remembered the word "tempering".
