Chapter 318： Blast furnace plan started

With the help of the clansmen, a large amount of sand was sprinkled in the burning charcoal storage room, and the terrifying smoke finally stopped gushing.

Parts of the collapsed furnace were cleaned up, and the solidified pig iron was collected on a large scale.

Cravason fulfilled his promise, and he paid the two silver coins agreed upon by the workers who helped the smelting.

So far, the situation has turned from danger to peace.

But the messy wreckage has not been completely cleaned up, and the storage room in the ruined state is still exuding an aura of anxiety.

In the evening, in Clavasson's home, the family sat together in a mixed mood, and in front of them, they were doing Rylik.

Everyone sat on the wooden floor and discussed the next thing.

The oil lamp was ignited by the powder, adding an important light to the dim room. The fire shining on Rurik’s immature face, for the Cravassen family, their desire to make a big stove really had to rely on Rurik’s help.

Some die-cast glass square plates contained a little dried fish, and a small bowl of oatmeal.

The blacksmith's stock of oats is almost gone, and the last little skill is planned to be used by Lilia after giving birth. Now, in order to get the help of Rurik, Klavasen had to offer his own gift.

Rurik didn't care.

The fact that the stove had collapsed was terrible, and at first, there was nothing to say about the Cravason and his son sitting here.

"Why? I'm not talking anymore?" Liurik asked deliberately with a grim face.

"This...what can I say?" Clavasson strained an old face full of beards. "I can only beg you to find some way. I hope we can still make a new big stove."

Rurik smiled calmly, holding the nearly hemispherical glass bowl in both hands, and took a sip of oatmeal: "I thought your home would be out of oats a long time ago, at least my home is exhausted."

Kawei smiled reluctantly: "The one thing left is for Lilia, but..."

"I understand." Rurik put down the bowl. "Why are you so careful? I said it during the day. Now we have a meeting and I will tell you what to do next."

"What to do?!" Cravason and his son stretched out their heads in unison.

"In a hurry? It doesn't matter."

"Oh." Clavasson patted his head, "I have seen the biggest furnace in my life, and I have also seen the furnace collapse. In fact, I want to know how it collapsed. Of course, there are also the special ones you said. Iron, smelliron, how it is produced."

"Huh? Can't you two senior blacksmiths understand?" Rurik shrugged, thinking their incomprehension was absurd.

"If I can understand, it won't let the stove collapse. Please tell me." Cravason hooked his head, looking humbly asking for advice. Upon seeing this, Kawei also hooked his head.

The atmosphere became a bit strange.

Rurik smiled and whispered: "Usually you smelt ore, sponge iron and **** will only press the bottom of the furnace, which is the hard ground! But now the situation has completely changed. You throw it into the furnace. You have too much ore, and you are eager to complete one month's sponge iron cost in just one smelting. Your ambition is too great."

Cravason suddenly realized: "Ah! Shouldn't we put so many ore? Oh, it's our own sin."

"Not only that." Lurik shook his head vigorously. "You have done a great thing. Your furnace melts the ore completely for the first time, but your furnace can melt the ore, but it cannot carry them well. It turns into water. Iron is very heavy, much heavier than slag! That is the smelliron, they are very heavy at the bottom of the furnace. Your furnace wall is still too thin, and it is completely broken by it."

Let the two blacksmiths and the blacksmith apprentices such as Kamnier who are leaning against the wooden wall, expect them to have an abstract concept of mechanics in a short time, I am afraid it is a little simple.

They do need to spend some time to understand the "classical mechanics" discovered and summarized by Sir Newton, but this does not mean that they have not realized many truths in the cumbersome daily production work. For example, Cravason and his son have their own experience summarizing concepts such as stress.

Cravason suddenly raised his head: "Oh! Then increase the thickness of the furnace wall."

"And next time, don't put too much ore." Kawei added.

"Huh? Do you think about that?"

"Otherwise?" Cravason asked.

"No." Rurik understood everything. He lifted his chin and kept pounding the wooden floor with his fingers: "My friends, since you can completely smelt iron ore, just like smelting bronze, Everything has changed."

"Oh, then put in a large clay crucible." Kawei suddenly realized, consciously found a means to take out the molten iron.

Rurik patted his face vigorously with both hands. He didn't know whether to praise Kawei for his linear thinking or judge him for being pedantic.

"Don't think about the crucible! You just listen to me. We work together to build a brand new furnace, but the internal structure will be unprecedented. You must make it according to my orders and it may be successful."

Cravason and his son looked at each other, and they had no objection.

Taking advantage of the opportunity, Rurik immediately taught all the blacksmiths and apprentices about the blast furnace.

As for how Rurik understands this knowledge, he knows quite well. This is the advanced theoretical knowledge he possesses as a traverser. Because of old blacksmiths like Kravassen, Rurik trusts the father and son to return Can continue to turn his theory into reality.

Here, Rurik also had to sigh for the persistence of the ancestors of the East for smelting.

Perhaps, the ancestors of the East accidentally used copper ore in the process of burning pottery. In the history of pottery for thousands of years, the mixed use of copper ore, tin ore and even lead ore led them to develop their own bronze smelting technique. .

In order to cast larger bronzes, a larger furnace must be used to smelt more bronze water. The ever-increasing demand forces people to constantly remodel the furnace.

The furnace is made bigger and bigger. In order to facilitate the collection of bronze water and the abandon of **** waste, a discharge port and a **** discharge port are set up.

In order to make the combustion more fully, we began to use high-quality charcoal, coupled with a large-scale animal-powered blower, to inject more fresh air into the furnace.

Compared with the leather bladder owned by the Ross people, the East has already used more advanced bellows and wooden fans, and its blowing efficiency is very amazing.

More air enters the furnace body, even charcoal can reach its calorific value limit, so in the age of smelting bronze, the height of Chu people can reach the extreme high temperature of 1400 ℃. Because of the problem of ore selection, the Chu Army weapons have a large amount of copper-iron alloys.

The smelting technology has reached an extreme height, and the urgent consumption of ordnance for war has forced the East to have a great demand for the further improvement of iron smelting technology.

However, the Rus tribe does not have a huge need for war, but the threat of war always comes to their door. In a challenging era where powerful enemies are waiting and allies are more ambiguous, Rurik is eager to obtain a relatively peaceful development opportunity. However, the successive face-offs of the times have made him see a **** reality-weakness is sin. .

Except for some twenty-year-old young people in the tribe who are eager to make a fortune by plundering in the name of revenge, the attitude of Otto and Rurik has tended to open up wasteland to obtain new living space and produce their own production. Need materials, especially grains such as oats and rye.

Now that a vigorous production movement has begun in many new settlements under Ross, there is a huge demand for a large number of metal tools and weapons.

However, only five families of the Ross tribe are professional blacksmiths, and the young blacksmiths are still a group of apprentices under ten years old. It is still unknown when the men of the steel squirrel tribe possess excellent iron-making skills.

It was the time when the green and yellow did not meet, and it was the time when the Rus tribe was rather weak.

So even if the Kravassen family did not take the lead in making a new furnace, Rurik would have to build a blast furnace. After all, compared to burning ore to make sponge iron, it is far less efficient than direct casting of pig iron to make tools. Although the quality of pig iron production tools and weapons is extremely worrying, it depends on who is compared. Since the opponent is usually wrapped in cowhide, only the elite is dressed in chain mail. To deal with this kind of enemy, the spearhead made of pig iron is thicker and heavier. As for using it to cast bones, gourds, or warhammers, and smash the enemy's bones with a blunt tool, there is no problem.

Therefore, for the new furnace mentioned by Rurik, its top priority is naturally the thicker furnace wall!

In order to make the furnace stronger, of course it needs to continue to be piled up with clay and fired into a giant pottery. It is best to use high-temperature resistant chromite ore from Elon Orava Fort to form a refractory layer. Perhaps the furnace’s ability to resist pressure is still weak after the furnace is built, so Rurik hopes that after the furnace is built, he will continue to stack sand on the outside of the furnace, and finally ramming it with a sledgehammer to become a solid mound for the furnace. Does not collapse.

An earthen blast furnace, its structure itself is not complicated.

Since the furnace is designed to deal with the separation of molten iron and slag, the density of the two substances is very different, so it is not difficult to install the **** outlet and the material outlet in different positions.

The so-called difficulty lies in the blower.

Since the four bladder blowers of the Cravasons, the nearly uninterrupted blast replaced by a group of big-waisted men, it seems that it is not a problem to promote the full combustion of charcoal.

But wait a minute! This blasting method itself is difficult to replicate, because it is impossible to hire people as strong as a bull as labor force.

Therefore, at this meeting, Lurik put forward two very important construction plans.

Without paper to draw a design drawing, Kravasson provided a pair of wooden boards, and Rurik used the tip of a meat-cutter knife to draw the basic structure of an earthen blast furnace on the wooden board. Because they also had a lot of experience in making utensils based on Rurik's drawings, Kravasson and Kawei's abstract understanding ability was greatly improved. They understood the blueprint of the earth blast furnace and couldn't help but applaud.

However, there is only another design drawing, two senior blacksmiths carefully looked at the oil lamp, still a little confused.

"What is this? I can't understand." Even the young Kawei was completely confused when he faced the "centrifugal blower" that Rurik took out.

"This is a special blower. Although it is made of wood and belts, your carpentry ability is very outstanding. I believe you can make it according to the drawings."

In fact, the wooden "centrifugal blower" produced by Rurik is essentially different from similar products after a thousand years, perhaps only in material. Its essence is a turbocharger system. As long as its airtightness is well done, its efficiency is better than that of a bellows blower, but its production is a test of mechanical knowledge.

It is precisely because it is more complicated to make. Dongfang is more willing to use cheap bellows and exhaust fans such as one-in-one blowers.

Although the centrifugal blower of fan car is also used for smelting, its appearance is too rare, and its simplified version is more used to hull rice and wheat.

The two of them looked dignified, and Rurik deliberately stimulated with words: "If you can't do it, I'll have to hire a better carpenter."

"Then let me come!" Clavasson gritted his teeth and sat upright, and then gave his son Kawei some instructions: "Tomorrow we will start to act, you bring the children and hire another group of people, you To make a stove. And I, I also hire a group of carpenters to work together to make Rurik’s blower."

Rurik was a little dazed: "Huh? Did you decide to hire someone?"

"Why not?" Cravason opened his eyes strangely.

"Oh! It's not surprising, it's just... it's nothing. You just do as I say."

After a meeting was over, Rurik was already excited when he returned to his home.

He is fantasizing about a beautiful picture, and his family members are all discussing the thrilling things that happened during the day.

Seeing his son return, Niya directly grabbed his hand and asked about the situation of the blacksmith's family.

"Are you worried about them? Mom."

"Of course! They should be okay." Niya was a little puzzled with his son's disapproving expression, "They are really okay."

"They are all safe. The fire is extinguished and the stove will be rebuilt tomorrow."

"Oh, I hope the stove won't collapse again, it's terrible."

"That's not true." After all, Rurik called all the women in the family to his side, especially Sister Carlotta.

"Now that all the Ostala people have not moved to Shilla Fort, they must have settled down, and I don't think they are willing to move anymore."

The words were for Carlotta. As the leader of Ostara, she nodded: "You are right, although you said last year and all move out today. I am here, of course everyone does not want to leave."

"Hey, you are their leader after all. But you are good at grazing, and you need a warmer place to graze cattle and sheep. Roseburg is not very suitable here."

Carlotta was surprised, and she muttered weakly: "Rurik, I'm obviously your woman, are you trying to let me leave... leave."

"Huh?" Rurik denied hurriedly: "I just said that your people will leave Roseburg sooner or later. This place is too barren. I am afraid I will leave this fjord in the future. Shilla Fort is warmer and it is suitable for grazing and planting. , The waters there are also suitable for fishing. Our destiny is to leave this fjord, so we need more tools."

The private owner himself said some nonsense, and Rurik hurriedly clapped his little hands: "You only went to the furnace to collapse, but you didn't know that the Cravasons had completely smelted iron ore into molten iron!"

Rurik's remarks were certainly exaggerated, and his remarks completely surpassed the knowledge of the family's female relatives. It's not that Sister Carlotta has never seen iron smelting, and here it is also that the two girls, Lumia and Sepolava, have accidentally understood the principle of iron smelting.

"The ore becomes water, can't it be poured?!" Carlotta asked in surprise.

"Yeah, you are so smart."

Carlotta smiled shyly, only for a moment, she finally understood all the hints of Rurik.

"Ah! We cast farm tools, and we use iron ore casting tools everywhere. Can each of us in Ostala have our own axe, shovel, and draft?"

"Yeah." Rurik said with a smile: "This is really enough to arrange for your people to open up wasteland. They will bring a full set of tools. By the way, there is a heavy plow. At that time, I am afraid I will tell the chief leader. Arrange for you to lead the tribe to build a settlement called New Ostara in Fort Shilla. Maybe you want..."

Carlota felt a little lost, but he also showed the temperament that a leader should have for the first time.

She straightened her small chest and looked at Rurik's eyes: "Even if I am a child, I will revive my tribe. My destiny is to be your wife, and my tribe is also your tribe."

"Yes. But your people will have to pay taxes in the future. This is a contract. When the brand-new stove starts mass production of tools, I will give a lot of tools to your people, but they will give them to me for generations. Pay tax. I think you know the concept of tax! They have to pay part of the grain harvest and leather, in the final analysis, it is for the expenses of our Ross tribe."

Carlotta sighed silently, and she felt that Rurik's words had something to do with: "Your tribe..."

For a moment, Rurik smiled consciously.

"Well, maybe I should spread an idea."

"What idea?" Carlotta asked.

"What is Rose. Is she a tribe, or an alliance, or everything about us? In my opinion, whether it is you, the Corvin or the deer breeder, as long as we are in the same group as the Rose, it is Rose. As long as he agrees with my father, as well as me and my children and grandchildren as the leader, then he can claim to be a Russian."

Rurik consciously said what he said was very clear. Here, the four female family members still feel inexplicable, or that Rurik's concept is a bit advanced and the atmosphere is noisy.

What can you do if you are faced with embarrassment? He smiled awkwardly, gritted his teeth and simply said: "Forget it! I will say it briefly, many years later I succeeded as the leader, as long as I agree to be loyal to me, the leader, and swear to me, I will agree that he is a Russian. , He can also claim to be a Rus. From now on, we will be from Corvin, deer breeder, Ostara, and Novgorod. We are all Rus."

Rurik is crazily suggesting a concept called "", which is also a "nation-state", in order to integrate multiple ethnic groups with different languages ​​and cultures into a brand-new national form, or fusion. A nation with many previous tribal cultures.

The concept is too advanced, and the atmosphere is still cold.

It is not their resistance, but in fact their concept of ethnic group itself is very vague. Even the Ostala people, they never mind condescending to a strong one, all they need is a stable living space. They didn't even linger about the concept of "Ostra" which was meant to describe a kind of island. The survivors can only rely on the kind-hearted Ross tribe to take care of them. What else can they ask for?

The scene was too embarrassing, and Liu Lixue simply waved his hand, "I'm tired, now I just want to rest."

"Then scrub your body and go to bed immediately." After that, Niya immediately called in the maid to prepare hot water.

I am afraid that Nina understands what her son says here. She marvels at his son's ambition, but is full of worries about the uncertainty of the future. However, I am really too old, and the future should be bright. Just like my son described a large amount of molten iron to make iron tools with unprecedented efficiency, I am afraid that this is the only one I can see in his lifetime.
