Prince of Chaos

Chapter 391 Fresh Things
Yang Chunyuan hesitated for a long time, but still took out the steel he had accidentally refined.

When Zhu Changluo saw this piece of steel, Zhu Changluo's eyes were deeply attracted by the color of this piece of steel.

This piece of steel is silvery white, and it seems to be a little shiny.However, this feeling is not particularly obvious.

When Yang Chunyuan brought the steel to Zhu Changluo, a name suddenly appeared in Zhu Changluo's mind!
The name is almost ready to come out!

Stainless steel!
It turned out to be stainless steel!

Zhu Changluo couldn't help casting a surprised look at Yang Chunyuan, he really didn't expect Yang Chunyuan to make stainless steel!

This is really beyond Zhu Changluo's imagination. In Zhu Changluo's consciousness, although stainless steel is common, it is also a kind of steel that is extremely difficult to forge. At least in this era, it is impossible to forge.

However, the piece of steel in front of me looks too much like stainless steel.

"Let alone touch."

Zhu Chang Luoan couldn't bear it anymore, he reached out and took the piece of steel from Yang Chunyuan's hand.

Zhu Changluo looked left and right, and then looked carefully. Based on the feel of the steel and the appearance of this piece of steel, Zhu Changluo concluded that it was stainless steel!
Zhu Changluo asked in surprise: "How did you make it?"

This question is better than Yang Chunyuan's question.

Yang Chunyuan faltered for a long time before saying, "I don't know either."

Hearing Yang Chunyuan say that he didn't know, Zhu Changluo didn't believe it.

Under the guidance of Zhu Changluo, the Xishan Institute of Technology requires that any experiment be recorded.Otherwise, how to summarize the law and how to make progress?
Is it possible to still rely on the old master's manufacturing method based on feeling?
Obviously, Zhu Changluo did not agree with this answer.

Yang Chunyuan looked at Zhu Changluo's expression, and he knew that Zhu Changluo didn't believe him.

Therefore, Yang Chunyuan explained nervously: "I really didn't lie, this piece of steel was made inadvertently. Later, when I forged it again according to the experimental records of the day, I couldn't forge it again. It's the second piece."

Zhu Changluo looked at his elder brother-in-law as if he was really anxious.

Zhu Changluo didn't force him to ask, Zhu Changluo said: "Go and find the experiment notes for that day."

When the experiment notes were found, Zhu Changluo opened the notes and read them carefully.

He found that the content written in this note was indeed very careful.

Described in detail the steel forging experiment process of the day, such as the color of the furnace fire before putting in the pig iron, and when to pour out the molten iron that was burnt into molten iron to solidify into blocks, and then record when it started forging, How long is the tempering time, how many times the carbon is put in during the period, and what is the weight of each carbon.

These are all recorded clearly and meticulously.It seems that there are no problems, but why can't it be reproduced again?
This question could not help but make Zhu Changluo fall into deep thought.

Zhu Changluo thought for a while, and then said: "Take Gu to see the pig iron for steelmaking."

Since it's not a problem with the steps, it must be a problem with the materials.

Zhu Changluo thought to himself: "If I remember correctly, stainless steel should be an alloy metal. The reason why Yang Chunyuan was able to make this piece of stainless steel by chance must be because he added other metals inadvertently. Otherwise, how could he Is it possible to make stainless steel?"

After arriving at the warehouse where the pig iron materials were placed, what Zhu Changluo saw were all kinds of khaki and brown iron ores, some of which were accompanied by black particles.

Zhu Changluo walked in front of these ores, and he picked up these ores of different colors and looked at them again and again.

Zhu Changluo asked: "What kind of ore was used for smelting that day?"

Yang Chunyuan said: "There are all of them. These iron ores were all transported from Ningxia, Shaanxi. They were all put together in the furnace, and they were never deliberately separated."

As soon as Zhu Changluo heard these words, he vaguely guessed where the problem was, and it must be the iron ore.

Zhu Changluo said: "Come here, distinguish these iron ores according to their colors, and then put them into the furnace for smelting according to the ores of different colors. I just want to see where the problem is."

With Zhu Changluo's order, iron ore of various colors were sorted out soon.

The khaki is a pile, the brown one is a pile, and the ore with black particles is a pile.

After the ores were sorted, Zhu Changluo said again: "Now start the furnace and start a fire, fill these ores into different furnaces for smelting, and then carefully record the conditions in the furnace."

"Yes!"

After Yang Chunyuan and others heard Zhu Changluo's order, they immediately moved.

Push the trolley over, pull these ores of different colors and send them to different blast furnaces for smelting.

At this time, Zhu Changluo was quietly waiting for the result.

Although he didn't know what other ingredients these ores contained, but according to the melting point principle of substances that Zhu Changluo knew, the melting points of different substances must be different.

At that time, after the iron ore melts, Zhu Changluo should be able to find the key material for making stainless steel.

After a while, several blast furnaces filled with different ores all emitted extremely hot temperatures.

The researchers responsible for checking and recording the situation in the furnace stood sweating profusely near the blast furnace, staring wide-eyed at the melting of the iron ore inside.

Soon, iron ore loaded with khakis and browns was already melting in the furnace.

Looking at the colors in the furnace as they melted, the researchers recorded them separately.

This recording method was reminded by Zhu Changluo. Zhu Changluo said: "The high temperature in the blast furnace has different colors at different temperatures. When we can't directly measure their temperature, we judge them by the color of the furnace fire." How high is the temperature!"

Therefore, since the establishment of this standard, Yang Chunyuan and the others have drawn up a variety of different temperature counts according to the different colors in the blast furnace.

And this kind of temperature counting is only a rough recording method, and they still have no way to record the exact number.

After all, the Xishan Institute of Technology has just produced a mercury thermometer under the guidance of Zhu Changluo.

Moreover, the difficulty of making this kind of mercury thermometer is still quite arduous. Up to now, few mercury thermometers have been made with accurate scales. Moreover, these mercury thermometers were all made by Liu Wenzhen and Li Shizhen with the support of Zhu Changluo. The disciples took it as treasures, and then only kept one on the Wanli Emperor's side and Zhu Changluo Ciqing Palace's side.

As the manufacturer of the mercury thermometer, the Xishan Institute of Technology did not leave a single one.

It's really depressing to think about it!

But who can say no?After all, this is the order of the Crown Prince also.Therefore, researchers who make thermometers can only continue to trial and error, continue to study, and try to find the trick one day earlier, so that they can make thermometers in large quantities.

After all, after having the experience of using a thermometer, it is much better to face the feeling of being unable to determine the temperature and only relying on body sensation!
It can be seen how addictive the precise application of the thermometer is.

As long as it is experienced, it will be unforgettable!
