Along with the memories, the dwarf Mulu completely narrated the process of refining this iron ball.
As he narrated, Xu Yi kept asking for details, even the temperature of the fire he used at the time.
"This... temperature?" Mulu scratched his messy hair, a little confused. "President Xu, you mean how big the fire is, right? I can't tell you. I can only tell you that I burned it as usual, and it wasn't particularly hot."
Xu Yi was a little helpless. Sainz Continent did not have detailed data records for all processes like on Earth. This was actually a major flaw in promoting industrialization. It seemed that he had to find a way to solve this problem.
Of course, this issue can only be postponed. The most important thing at the moment is the iron ball in hand.
After asking Mulu several times, Xu Yi couldn't get a satisfactory answer, and finally had to ask Mulu to simply rehearse the process that day.
Hearing that President Xu of the Xinfei Chamber of Commerce was interested in the iron balls refined by Mulu, other dwarves who were conducting smelting experiments also gathered around.
In front of everyone, Mulu thought for a while and lit a bright fire.
The first half of the smelting process was just a normal smelting process. Xu Yi didn't see anything special. However, when the molten iron in the boiler began to roll, Mulu picked up a can of silvery powder and poured it in. The situation changed instantly.
As soon as the silver leaf grass powder was poured in, it immediately melted with the molten iron in the boiler. After a while, the molten iron that was already rolling due to the high temperature began to roll even more violently. The originally red molten iron simultaneously It also began to be mixed with traces of silver light.
The process of iron-making is actually quite boring. Shluka was worried that Xu Yi would be bored at first, but he found that Xu Yi was staring at the molten iron in the boiler from beginning to end, with almost unblinking eyes and a positive expression. Focused, I couldn't help but wonder.
Why does President Xu care so much about this strange so-called alloy
It was already afternoon when Xu Yi came to the dwarf tribe, and by the time the furnace of molten iron was successfully refined, night had already fallen.
During this period, Xu Yi stayed beside the boiler and remained motionless except for a trip to the toilet.
In addition, he also took out a notebook and recorded the entire process, as well as the order and amount of materials used by Mulu.
After the molten iron cooled and gradually formed a round ball in the mold, Xu Yi carefully compared the iron ball this time with the iron ball he found before and determined that there was not much difference between the two iron balls. Only then was it confirmed that Muru had really restored the smelting process last time.
Seeing that it was getting late, Shluka wanted to invite Xu Yi back to the tribe for dinner, but Xu Yi refused directly.
After finally discovering a new type of alloy, Xu Yi was in a state of excitement. As a mechanical engineer, his work enthusiasm was bursting, so naturally he couldn't bear to leave at this time.
So Shluka simply asked the tribesmen to bring their dinner here. While the dwarves were eating dinner with Xu Yi, they conducted various tests on the iron ball according to Xu Yi's requirements.
After a series of tests, Xu Yi finally determined that the alloy that had undergone strange changes due to the addition of silver leaf grass powder may be slightly inferior in hardness, but its ductility and plasticity are very close to ordinary aluminum alloys on the earth. The pig iron commonly refined on the Sainz continent is much stronger.
More importantly, the alloy mixed with silver leaf grass powder has been piled in the corner for nearly two months, but no rust has appeared at all.
It actually has the properties of stainless steel without even any anti-rust treatment!
Xu Yi was extremely excited as he held the iron ball that was somewhat deformed after undergoing various performance tests.
The reason why he came to the dwarf tribe this time was actually because Chief Shluka had contacted the dwarves of other dwarf tribes. He came to try to get some more dwarves to join the magic machine tool workshop. Unexpectedly, the expected dwarves were not seen. , but unexpectedly discovered such a novel alloy.
Although it has not yet undergone any identification, Xu is certain that this new alloy, which he temporarily named Silver Leaf Alloy, may be difficult to apply to large magic machines due to its hardness, but it will definitely be used on light household magic machines. Has a very wide range of uses.
For example, if this alloy is used in the magic rice cooker recently developed and promoted by Xinfei Chamber of Commerce, the weight of the magic rice cooker will be reduced significantly.
This alone will definitely make the Magic Rice Cooker more popular.
After the multi-faceted tests on the silver leaf alloy were completed, Xu Yi immediately made a request to the Shluka clan leader, hoping that he and the dwarves in the tribe would conduct more multi-faceted tests on this silver leaf alloy.
For example, changing the content of silver leaf grass powder added, changing the temperature of the fire, adding some additional materials, etc...
At the same time, he also publicly rewarded Mulu with twenty gold coins in the name of the Xinfei Chamber of Commerce as a commendation for his invention of a new alloy.
Based on Xu Yi's understanding of material testing on Earth, he believed that any small change could change the final properties of the alloy.
The appearance of this silver leaf alloy was due to an accident. If there were more accidents like this, he would definitely support it strongly.
In addition to the silver leaf alloy, Xu Yi rummaged through the pile of discarded iron balls again and found a somewhat special iron ball.
Although this iron ball is not as conspicuous as silver leaf alloy, and its performance is not that outstanding, after testing, Xu Yi was surprised to find that this iron ball greatly exceeded ordinary pig iron in terms of hardness and wear resistance.
For heavy machinery, especially large machine tools, such alloy steel is extremely needed.
Xu Yi once again made a request to Chief Shluka to let the dwarves of the tribe conduct further research on this alloy steel at the same time.
This time, Patriarch Shluka did not agree as readily as before, but looked embarrassed.
"President Xu, I'm afraid there aren't enough tribesmen in the tribe now. If you hadn't taken Kanby and the others away, it would be no problem to conduct research on these two aspects at the same time, but now you have seen that the tribe can still do these things. All the tribesmen are here, and there are only a dozen of them, so I’m afraid I won’t be able to fulfill your request.”
Xu Yi looked around and found that Chief Shluka was not exaggerating.
Since he pulled a hundred dwarves led by Canby away from the tribe, most of the remaining dwarves in the tribe are old, weak, women and children, and only ten of them are still able to perform high-intensity smelting. Just a few dwarves.
"Well, Chief Shluka, isn't the Angola tribe coming to negotiate with me tomorrow? I'll talk to them about this matter then, and it's best to convince their tribe to take over the research on one of the alloys. Of course, it's best As the leader of Shluka, you can contact more dwarf brothers. Now I am in urgent need of manpower, mainly qualified dwarf craftsmen. How many are needed?" Xu Yi thought for a while.
Shluka did not agree immediately, but frowned and looked at Xu Yi.
"President Xu, do you plan to fill your factory with dwarves?"
Xu Yi was startled: "Of course not. There are still more humans in my factory now."
Shluka shook his head: "President Xu, I think I have to remind you that if there are too many of us dwarves in your factory, I'm afraid there will be problems."
Xu Yi was a little confused: "Something went wrong? What could go wrong? I just let the dwarf brothers go to work at my place, what could go wrong?"
Shluka sighed: "President Xu, I know you have good intentions, but not all of you humans may be like you. More importantly, your human leaders may not think so. We dwarves have It’s okay for a small number to appear in your human society, but if a large number of dwarves appear together, I’m worried that it will cause trouble for both you and us dwarves.”
Xu Yi couldn't help but frown: "Racial wars happened thousands of years ago. Are you still worried about this, Chief Shluka?"
Chief Shluka waved his hand: "It is impossible for another race war to happen. I am just worried that it will arouse the alertness of your human leaders. By then, our dwarf brothers will not be able to bring you any benefits, but will bring you trouble." ”
Xu Yi pondered for a moment, and finally had to admit that Chief Shluka was right.
Although the Sainz continent is currently dominated by humans, and other races have no capital to compete with humans, racial barriers still exist.
There is no problem for Xu Yi to recruit a hundred or hundreds of dwarves to work for him, but if he recruits thousands or even thousands of dwarves, it is likely to arouse the vigilance of the big shots in the Lampali Kingdom.
You have so many aliens under your command, do you want to rebel
"Alas, it seems that no matter which world we are in, business cannot completely get rid of political factors." Xu Yi sighed inwardly, thought about it, and nodded to Patriarch Shluka: "Thank you, Patriarch, for your reminder. I will pay attention to this issue. . But I think there won't be any problems in this area at this stage. Besides, my Chamber of Commerce is indeed very short of manpower, so please pay more attention to this aspect. If it doesn't work, I can't say that it doesn't happen at all. Prepare."
President Shluka nodded his big head gently: "Okay, President Xu, you are a smart human being. I believe you will have a solution. As for the dwarf brothers from other tribes, there is no need to worry..." At this point, President Shluka had a wry smile on his face, looking helpless. “Their current life is no better than our tribe’s before.”
