Materials science is an important foundation for technological advancement and implementation. Even if the world has the magical power to nourish this, it is inevitable that it is necessary to study more suitable materials in the end.

After all, the level of warming is determined by the upper limit of the original material, and what provides this upper limit is the characteristics of the original material itself. Just like most woods cannot exceed the same intensity of steel in terms of strength.

Of course, for different materials, it is not impossible for highly warm-raising wood to have a strength exceeding steel, but the time and energy required to be invested, as well as its own upper limit, all need to be considered. For all materials, the more obvious the basic characteristics are, the stronger the characteristics after warm-raising.

In other words, the higher the base strength, the higher the strength after warming up. This is why Chen Xi must make technical reserves, and alloys are still very useful.

Chen Xi looked at Pu Yuan. He dared to guarantee that these people gave up the idea of ​​continuing to create new alloys after they found that there was no results in a short-term experiment, but kept investing their energy in existing materials for deeper research.

This belongs to another thinking route, that is, to push the original technology to a higher level, even if it is just ordinary steel, some people can play with it on carbon steel.

However, this method has an end in the end. Just like the steam engine route and the internal combustion engine route, it can continue to develop on the steam engine route, which can indeed be optimized to a certain extent and improve the transmission efficiency. However, the internal combustion engine path can go faster and surpass the steam engine in a short time.

"Is there any finished product?" Chen Xi felt that he should not express his dissatisfaction directly. He still said to Pu Yuan with the dull look he had before.

Pu Yuan nodded and asked someone to quickly pick up a batch of long swords that were just wrapped in velvet cloth at the head of the sword. It was about one meter two in length, which was already a long sword far beyond the normal level.

Generally speaking, when using a long sword of this level, it is very likely that the sword is too long and the structure is unreasonable, and then it is cut off from the center of the sword spine by a sword. In addition, when the sword is too long and slashed, the force in the front and rear is very likely to be broken from the middle.

"Zhongkang, come and try it." Liu Bei took the strange long sword, tried it twice, and handed it to Xu Chu. Although Liu Bei's swordsmanship is pretty good, if it is the evaluation materials, it is more appropriate to hand it over to Xu Chu.

Xu Chu said nothing extra, and took the long sword and waved it a few times. A strong shock sound appeared directly on both sides of the sword blade. Then he nodded slightly, and then touched his sword and the sword handed to him by Pu Yuan, with a solemn expression.

"The steel blade of manganese steel?" Chen Xi squinted his eyes and looked at the gap. The strength and sharpness are currently the strongest manganese steel, of course, and of course the most brittle one. However, the toughness of this sword is very good, which means it cannot be all manganese steel.

"Yes, the steel blade of manganese steel and the sword ridge of nickel steel." Pu Yuan nodded. This was his recent masterpiece, and more importantly, the technology can be popularized.

If Pu Yuan could make it himself, that would be nothing. Pu Yuan himself was the strongest sword-casting master in the world. Sword casting and sword making are within Pu Yuan's ability. Not to mention making such a very ordinary long sword, even a serious famous sword or a divine sword is possible.

Chen Xi nodded. To a certain extent, Chen Xi admitted that this technology can fool himself. After all, materials science is only one aspect. What Chen Xi wants is new technology, whether it can be used now or new technology in the future, it is OK.

Although the technology Pu Yuan can only be used on some weapons, for Chen Xi, some of them are good even if they are used, and how to adjust the ratio and adjustment of manganese steel and nickel steel is of great value for in-depth research.

As for other alloys, it is definitely necessary to study them, but you can remind these people when you leave again, there is no need to make it clear at this time.

Face still needs to be given. After all, in terms of output, Bingzhou Smelting Department is still very qualified, and there is no need to make these people unable to get out of the market.

"How much is the waste gas produced in the water? "Chen Xi silently changed the topic and asked, without further investigation of the alloy.

Pu Yuan looked much solemn when he heard this. He didn't make alloys, or he didn't want to make alloys, mainly because he was studying sulfuric acid, because this thing was so interesting.

"I have collected a lot, but this thing is quite dangerous. Such swords will be melted easily." Pu Yuan sighed and said, "In the past two years, we have had many accidents around this thing, explosions, and burns."

"Burt?" Chen Xi raised his eyebrows. This was very professional. It was obvious that he had created concentrated sulfuric acid and then made new attempts there.

"Yes, we have made a lot of attempts, and of course we have also developed some new usages." Pu Yuan said seriously, "We use this thing to wash the ore, and there will be some things worth our research in the slag left behind."

When he said this, Pu Yuan's expression was much more excited. It was not that people like Xinlian couldn't really get it out, but they were not interested in this aspect. They were all thinking about studying sulfuric acid. They only sent people to adjust and study the formula given to Chen Xi that year.

Chen Xi nodded silently when he heard this. The ore here contains a lot of things. Pyrite is one aspect, and there are some other ores, but it is difficult to deal with when mixed together. However, in Puyuan's current situation where sulfuric acid is not considered cost, the pickling method can definitely wash out some other metals.

These metals are basically one of the basic materials used to make alloys.

"In other words, I have already started trying to use these things." Chen Xi touched his chin. People in the Central Plains have a strong ability to cause trouble. In this situation, Pu Yuan should have already developed a replacement reaction in the chemistry system.

In other words, it is not that new materials have not been produced, but that they are just staying at the laboratory level. To some extent, it is considered successful.

"After some materials are added, the prepared steel will have a very unique effect. The gas produced by the reaction of dilute sulfuric acid and steel is collected by us to use it as combustion consumables. After pressurizing and spitting fire, the power is very reliable." Pu Yuan was quite excited when he said this, and it was obvious that he had tried it.

"Oh, I roughly understand." Chen Xi nodded. Playing with fire is an inevitable thing for normal people. Many things have a sense of beauty when burning, and humans can even burn things to feel excited. Pu Yuan probably also made this happen.

"Is there any finished product?" Chen Xi asked curiously.

Pu Yuan nodded and asked someone to go back to his place to take the newly cast swords. At this time, Chen Xi could no longer tell the quality of the swords, so he could only leave them to Xu Chu to feel. After Xu Chu tried it briefly, he realized that the casting level of these swords was far greater than the swords he currently uses.

"It seems that you have basically mastered what to add." After Xu Chu told Chen Xi about his judgment, Chen Xi, who was originally calm, had a smile on his face naturally.

There is no doubt that it is just like Xiangli who doesn’t know what antimony is. For these people, they only need to know where ore I add and what kind of materials can produce what kind of results. As for what this thing is called, it doesn’t matter.

Pu Yuan was a little confused by Chen Xi's call, and he didn't know how to answer. He came here just to use local materials to make swords. He was so involved in the management of business because there were very few talents who knew metal smelting. Pu Yuan himself was one of the top talents and was engaged in research in Bingzhou, so he was forcibly recruited.

But Pu Yuan thought that he hadn't done anything in the past few years. In Pu Yuan's opinion, there was nothing he needed to make for blast furnace smelting. It was much more reliable than his previous steel frying method. When the steel was poured out at a furnace, even if the quality was not as good as the molten steel he made, it was better than the quantity.

In addition to the magical method of remaking the furnace, Pu Yuan's opinion is a very excellent technology, especially when adding other things to it during alloy smelting, which makes Pu Yuan's eye-opener. Therefore, Pu Yuan can at most help manually adjust the material ratio.

As for the design and adjustment of first-line steel furnaces, those workers did better than Pu Yuan. There was no way. After all, this factory clearly stipulates that as long as the steel furnace is adjusted and is indeed members who have improved efficiency, they will be rewarded.

Therefore, the front-line smelting workers also stared at the blast furnace and found a place to improve. The bonus paid was enough for the whole family to eat and drink this year.

So Pu Yuan only needs to hand over the ratio he made to others, and then let them adjust the ratio by blast furnace steelmaking.

After all, laboratory preparation and industrial preparation are two different things. Although problems will inevitably arise from laboratory to industrial preparation, which will lead to a burning furnace of steel, the finished steel can also be used to produce agricultural tools. Anyway, this is also steel.

However, later Pu Yuan was addicted to pickling and washed a lot of ore with sulfuric pickling, and washed out a large amount of special metals. Then he added these metals to the steel on his own territory, made into new alloys, and finally cast them into swords.

To a certain extent, Pu Yuan has completed the alloy preparation formula. After all, the materials that can be used to make swords are relatively reliable in terms of strength and toughness, but Pu Yuan uses pickling method.

Simply put, I can do it in the laboratory, but I can’t do it in industrialization, and there are also material ratios, but how to mine and obtain this part of the additives is a big problem.
