The bellows technology is a loss, but now Tianyou knows the value of those technologies in his hands, and he will not suffer a loss if there is such a thing in the future, and he is now considered to have penetrated into the enemy, and he must thoroughly understand the actual needs of the refiners, so as to better estimate the value of the technology in his hands.

After the bellows episode passed, Zhenyuan Shangxian began to ask Tianyou how to solve the problems of burrs, fine lines and pores on the surface of the embryo.

Tianyou didn't answer right away, but was estimating the technical level of Zixiao Palace's side.

Although the set of things on the earth is advanced, it may not be suitable for Zixiao Palace. First, the technology that exists on the earth may not be able to be copied by the Zixiao Palace, and secondly, the Zixiao Palace also has its own technical advantages. Not to mention anything else, this enchantment technology alone can throw ten streets of the earth. The fire spirit enchantment that had a counter-effect before and caused the experiment to fail, the effect is simply the same as the energy shield in a science fiction movie, the five major hooligans on the earth can fight it, but Zixiao Palace has already popularized it.

It would be a waste not to take advantage of such a big advantage.

After talking to Zhenyuan Shangxian about his needs, Zhenyuan Shangxian immediately introduced Tianyou to the techniques and methods of the Treasure Weapon Sect, so that Tianyou could think of a better way.

Of course, this is a big project, Zhenyuan Shangxian introduced it until it was dark in one breath to roughly explain the technical status of the Treasure Weapon Sect, and then took advantage of the meal time Tianyou made a draft in his heart, and thought about how to use the existing technology of the Treasure Weapon Sect in detail, and then combined with the earth technology he mastered to produce the best plan.

Zhenyuan Shangxian was anxious, and he was afraid of disrupting Tianyou's train of thought, so he didn't dare to urge him, until he couldn't help but ask after the meal.

Tianyou also had a plan at this time, so he simply explained to Zhenyuan Shangxian. "The disciple has already thought about it. To solve this problem, we still have to start with casting technology. The acquired treatment can only eliminate the surface burrs and pores, but the impurities and uneven structure inside the embryo cannot be removed by surface treatment, so even if the previous acid solution is successful, it only makes the surface that is not smooth a little, and the main body of the embryo as the substrate is still the same. ”

Zhenyuan Shangxian nodded and said: "We have also thought about what you said, but now we have no other way, we can only think of improving a little is a little, it is better than doing nothing, right?"

Tianyou nodded, "That's true, but I have a way to solve the problem in essence." ”

"Oh, what's the method?" Zhenyuan Shangxian began to get excited as soon as he heard this.

"The approach is not about one aspect, it's about improving across the board. "To solve the problem of internal impurities and stomata we need to start from multiple directions to eliminate all kinds of drawbacks that affect the structure of the embryo. The first step is to no longer use metal ore to cast the embryo, but first smelt the ore into high-purity metal ingots, and then directly use the metal ingots to make the embryo. ”

"Why do you have to do two steps?"

"Because we're refining tools, not iron. ”

Tianyou's answer made everyone a little stunned, but Lu Meng reacted. Of course, this is mainly because she runs the Hundred Soldiers Workshop herself, so she knows more about business, and relatively speaking, Zhenyuan Shangxian and Ye Sanshan have no experience at all.

Lu Meng, who figured it out, shouted: "I understand." We are casting the embryos needed to refine the magic tools, and we want quality rather than quantity. The blacksmith shop uses iron ore to refine wrought iron, and then directly smelts it into utensils without cooling, which is to save costs and time. And we don't care about the cost at all, so instead of wasting time and effort to smelt iron ore, we should buy wrought iron directly and process it. ”

"Oh, I see. Ye Sanshan also reacted after listening to Lu Meng's explanation. The status of these monks is not the same as that of ordinary people, if they even have to smelt iron ore themselves, this delayed time is really a waste, and the extra price of enough to buy wrought iron is really nothing.

"Actually, Lu Meng, what you said is not entirely right. Tianyou corrected: "The choice of wrought iron instead of ore also has the purpose of saving costs. On the surface, the amount of wrought iron extracted from iron ore bought with the same money is more than that of wrought iron bought directly with money, but have you ever thought about it? Zixiao Palace is located on the top of the mountain, and the transportation is inconvenient, and the volume of this ore is huge compared with wrought iron.

Besides, all the people in this Treasure Sect are monks, and asking you to refine this iron ore is a complete waste of your skills and abilities, and this labor cost is the big one. Therefore, buying wrought iron directly is not an extra cost for Zixiao Palace, but a way to save it. ”

The monks and the folk blacksmiths in the Zixiao Palace are equivalent to the comparison between the engineers and the migrant workers in the construction team. If you ask the engineer to draw drawings and design plans, of course there is no problem, but if a construction team invites a bunch of engineers to come back to move bricks and build walls, then the labor cost must not make the contractor have a heart attack?

Therefore, the rough work can be thrown to the blacksmith to do, and the Zixiao Palace side can specialize in the part that the blacksmith can't do.

After Zhenyuan Shangxian understood what Tianyou meant, he motioned for him to continue, and Tianyou did not sell Guanzi, and continued: "Cost saving is only incidental, the key purpose of directly using wrought iron is to improve the quality of the embryo. And the way to do that is to improve the furnace. In addition, the furnace scheme I designed was not convenient for cleaning the iron slag, so it was necessary to apply wrought iron directly instead of ore. ”

"You really have the technology to press the bottom of the box. Lu Meng asked with great interest: "How do you say this furnace should be changed? Is it based on the centipede furnace of my Hundred Soldiers Workshop, or is it based on the gossip furnace of our Divine Soldier Sect?"

Or how to say that the embryo is difficult to make. This Zixiao Palace refining embryo is not the same as the blacksmith making agricultural tools, they need to introduce the spirit array during the smelting process, so this furnace cannot be closed.

You say that these four open furnaces, how can they burn up at this temperature?

It's also thanks to the fact that Zixiao Palace has a fire spirit enchantment that can temporarily close the furnace, otherwise they are afraid that they will not even be able to smelt.

Tianyou smiled and shook his head when he heard Lu Meng's question. "Neither. The one I designed is called a hearth. ”

"The hearth, the furnace buried in the ground?" Ye Sanshan understood it directly from the literal meaning, but he didn't expect Tianyou to nod directly.

"Yes, a hearth is a furnace that is buried in the ground. Without waiting for them to ask Tianyou, he began to explain: "The Bagua Furnace used by the Treasure Weapon Sect before used double heating inside and outside, the outside of the furnace was kept warm by firewood, the furnace was embedded with a fire spirit enchantment, and the innermost crucible was coke. Although three layers of heat sources are used, the furnace body is too tall, there is no thermal insulation around it, the heat loss is too large, and the furnace is open, so the temperature is even more difficult to raise.

The hearth I designed was different. The furnace is directly buried in the ground, and the hollow refractory bricks are laid outside, because the furnace is directly dug to make a furnace, so there is no need to worry about weight and support, the furnace wall can be as thick as possible, thermal insulation, and only a small amount of coke can reach extremely high temperatures. ”

"But this hearth is buried in the ground, what should I do with the charcoal fire? Is it put on the top of the stove? Isn't that called a flower chicken?"

"When the heat rises, the fire naturally cannot be heated on the stove, so the flame still has to be placed under the furnace body. As for Lu Meng, you are worried about the problem that the furnace is not breathable and the flame cannot burn...... It's easy. As I said before, hollow refractory bricks are used. This brick needs to be specially fired, and there is an air duct inside the brick, one is insulated, and the other can be a channel for transporting air. There is a bellows connected to the active air infusion, and it is not troublesome to catch fire under the furnace, but the first problem is that the packing port must be set aside for the later addition of fuel. ”

Zhenyuan Shangxian They are all experts in this area, although they haven't seen the real thing, but listening to Tianyou's introduction, they can imagine what it looks like. The thought of this whole furnace embedded in the ground immediately made it clear that this furnace must be heating up extremely quickly. After all, there is no heat loss, and the heat of the flame is completely retained in the furnace, so it is strange that the temperature does not rise quickly.

"What else?" asked Zhenyuan Shangxian excitedly.

"That's it for the stove, and there's the issue of enchantments. ”

"What kind of enchantment do you need?"

"Dare to ask if this barrier may shrink?"

"Shrinkage?" Zhenyuan Shangxian was slightly stunned. "You mean to squeeze the space within the barrier?"

"Yes. ”

"It's not that hard. ”

"In that case, it's easy to do. Tianyou continued: "With this hearth, the temperature of the furnace must easily reach an extremely high state, and even if the fire is extinguished, the heat will not disappear immediately. At the same time, there is another way to use this furnace - smoldering. ”

"Smoldering, God bless you for cooking?" Lu Meng began to complain again.

Unexpectedly, Tianyou nodded directly and said, "Yes, it's the same as cooking." As long as the top of the hearth is sealed, it is difficult to lose the internal temperature, and only a small amount of charcoal fire is needed to stabilize the temperature for a long time. By smoldering in this way, the carbon in the iron is removed, resulting in wrought iron of the highest possible purity. ”

"Eh, didn't you let us buy wrought iron directly? Why is it still wrought iron after smelting?"

"Because the wrought iron refined in the blacksmith is not pure enough, only we can purify it ourselves. Tianyou said and gave Zhenyuan to the immortals, and they popularized the essential difference between pig iron, wrought iron and steel.

In fact, these three things are all ferroalloys, and the difference is only the amount of carbon.

Wrought iron with a carbon content of less than 0.05% is soft and malleable, but the hardness is terrible.

Steel with a carbon content of 0.05%~2.0% is characterized by high hardness, good ductility, and certain toughness, which can be tempered or bent continuously.

The carbon content between 2.0% ~ 6.67 is the so-called pig iron. This thing is very brittle, a few percent is fine, as the carbon content rises, it will eventually turn directly into tofu residue, and it will fall apart when touched.

The blacksmiths are desperately burning iron ore when refining iron ore, and then after the iron is melted, the carbon in it is almost burned, so the direct refining is generally wrought iron, and the carbon content is relatively low. Later, because the iron was too soft, someone invented the method of burning coke and iron ore together, so that some carbon could be added to the iron, and then pig iron was obtained.

Although pig iron is brittle, it has a high hardness, so it was more useful than wrought iron for ancient people. Of course, the pig iron mentioned here is the kind with a carbon content close to steel, not the kind that is turned into tofu slag.

In fact, the reason why the pig iron made by ancient blacksmiths has a high carbon content is mainly because it is difficult to control the carbon content. Because they didn't understand the principle, the ancient craftsmen could only analyze and ponder according to the phenomenon, so in the end all they got was pig iron. As for the steel ...... They used a more subtle method to get it, and that was fusion.

Pig iron is because the carbon content is too high, and wrought iron is because the carbon content is too low, so what about mixing them together?

So, after some attempts to add more water and more water, the ancient craftsmen came up with the steel filling method, so as to obtain the steel with unstable performance. Of course, the main reason is that the carbon content is not easy to control. After all, they don't have measuring tools, and the carbon content of pig iron and wrought iron used by them is unknown, and the carbon content after melting together is even more unknown to God.

Tianyou used the metaphor of ink and water to explain the above theories to Zhenyuan Shangxian and them. After confirming that they all understood, he concluded: "Therefore, it is obviously easier and more accurate to make ink by adding water directly than to mix a cup of ink with a cup of ink that is too strong and a glass of washing water."

The steel filling method is good, the method is simple and convenient for mass production, but we are not going to manufacture in batches. The embryo wants quality rather than quantity, so we directly use the smoldering method to cook the wrought iron thoroughly, and then add carbon to adjust it directly to the required ratio.3 This can ensure the output of the required good steel. ”

Zhenyuan Shangxian nodded when he heard this, and praised: "Although it has not been experimented yet, this method sounds really feasible, God bless you, what should I do after that?"

"After that, we need to test the different ratios a few more times and then document the properties of the finished steel. In this way, whether you need harder or softer steel in the future can be controlled at will. ”

Just now, Zhenyuan Shangxian was just happy, and when he heard this, he stood up directly. He was really amazed that the method mentioned by God You could precisely control the properties of the steel produced as needed. This was a matter of course in the eyes of Tianyou, who had crossed over, but in the eyes of Zhenyuan Shangxian, who basically relied on great luck in refining weapons, it was simply shocking.

Before hearing about Tianyou's theories, in Zhenyuan Shangxian's cognition, those who can roughly control the performance of steel are already masters, and Tianyou actually said that they can control the performance of steel at will according to their needs, and the result is really amazing. If it weren't for Tianyou's detailed explanation, so that they understood the principle, in other words, they would definitely be thrown out by Zhenyuan Shangxian directly.

"You say you want whatever steel you want? Who are you? Lao Tzu is a god, don't you still have to try your luck to produce a good furnace of steel?"

Zhenyuan Shangxian was excited, but Tianyou threw out a dose of fierce medicine at this time.

"Carbon alone isn't enough. Good steel isn't just about iron and the right amount of carbon, there's got to be something else. Just like the bronze, which is originally a mixture of iron and white lead, its performance is much better than that of wrought copper. In fact, this steel is the same, carbon alone is not enough, you need to add some other things to get a steel with excellent performance. Of course, the specific ratio requires long-term experiments, and a complete system should be built to gradually measure the effect of different ratios, so that the steel performance can be higher and higher in the future. As for now...... The disciple had several ready-made recipes in his hands. ”

"What? you have the recipe in your hand?" asked Zhenyuan Shangxian excitedly.

Tianyou directly took out the Smith Wesson bear claws that he used to peel them, and then handed them over. "This is the multi-purpose knife that the disciple used to build by himself, and Immortal Venerable can try how good it is. ”

Tianyou's bear claw is a fine product that has been obtained after refining and scrapping I don't know how many times, and it has been kept by his side, which shows that the performance is outstanding. After Zhenyuan Shangxian took it, he immediately tried it on the stone table next to him. It didn't take much effort to scratch a scratch nearly half an inch deep on the stone table, and Ye Sanshan and Lu Meng were startled when they saw it.

Zhenyuan Shangxian was also excited after trying it, "I can't imagine that this kind of mortal iron can be sharp without any spiritual energy infusion, and this steel can be called the best." God bless you, do you have this recipe too? Tell me, I'm going to try it right away. ”

Seeing that Zhenyuan Shangxian was as excited as a child, Tianyou suddenly stopped talking.

I tried my best to answer questions and solve doubts for Zhenyuan Shangxian before, on the one hand, it was to repay Zhenyuan Shangxian for his support and care, so that he would take fewer detours, but the main purpose of Tianyou is to make benefits.

He had already suffered a big loss when he sold the bellows technology to Lu Meng, and now that he knows the significance of these technologies to Zixiao Palace, how can Tianyou continue to suffer losses? Besides, although he suffered a loss when he sold it to Lu Meng last time, he actually collected money after all. Could it be that Zhenyuan Shangxian can still let him give it away for nothing this time?

"That...... Immortal Venerable ......"

"What?

"No, the disciple is only embarrassed to say something. ”

"Huh?" Zhenyuan Shangxian didn't react for a while. "If you have anything to say, just say it. ”

Zhenyuan Shangxian was too focused on the new formula, and he didn't expect Tianyou to be asking for benefits for a while, but he was so confused that Tianyou didn't know how to speak. After all, it always feels a little embarrassing to ask for benefits directly. He just thought that Zhenyuan Shangxian was smart enough, and he could understand what he meant just by hinting at it, which made it difficult for him to ride a tiger.

After struggling for a long time, under the repeated urging of Zhenyuan Shangxian, Tianyou finally became wise in a hurry, and thought of a way, that is, he could get the benefits of value, and he would not appear to be snobbish, and he had finally established a good image in the minds of Zhenyuan Shangxian.

"In that case, then Immortal Venerable, did I really say it?" Tianyou asked cautiously.

Zhenyuan Shangxian, who was already impatient, saw that Tianyou was still there, and couldn't help urging: "You should say it quickly." Are you trying to kill me in a hurry?"
