Daming Military Empire

Chapter 416 Metal Smelting
After being kicked out of the Kunning Palace by the empress dowagers of the two palaces, Zhu Cijiong finally recovered from the ecstasy of becoming a father for the first time. Regarding the two suggestions given by the empress dowagers of the two palaces, whether to be busy with state affairs or live in the harem is actually no choice , the two are not contradictory, he is busy with state affairs during the day, and he is not allowed to live in the harem at night, and the Kunning Palace does not allow him to live.

The state affairs are not busy at all. What he wants to do most now is to develop precision machine tools, but the knowledge given by the system is too large and complex, which has far exceeded the technical level of this period. If he explains it to others, it is estimated that Years or even decades can't be finished, and it's even far away to make precision machine tools.

Zhu Cijiong thought about it for a long time, and felt that only by classifying all the knowledge and teaching it to professionals to study, and then putting it together according to the research progress of various knowledge, could it be possible to manufacture the prototype of precision machine tools in a short period of time. As for how far this prototype is from ordinary machine tools in later generations, it depends on the current technical level and the acceptance ability of various talents.

How is this class divided?In fact, the structure of the machine tool is not complicated, it is nothing more than a power source, a mechanism for transmitting power and a metal cutting tool for final processing and execution.

Divide all knowledge into three categories according to the structure of machine tools. This should be the simplest and most appropriate classification method. If you insist on classifying by discipline, it is not to develop machine tools, but to establish a scientific system. Gao, don't even think about it in this day and age.

The first one is the power source. This is not complicated. In the past, steam-powered pistons were used, but now they need to be replaced with electric-driven motors. The electricity is already available, and professionals are also available, namely Xu Fuyuan and Xia Yunyi. As for the motor, it is Leave it to the two of them to develop it, it shouldn't be very difficult.

The second one is the transmission device, which is not complicated. In the past, gear transmission was used, but now it is changed to a reducer. The reducer is simply a gearbox, which is just a package of specific gears. This is just a structural The problem is not technically difficult, and Wang Zheng should be able to do it soon.

The third one is metal cutting tools, which is more difficult. In the past, high-carbon steel was used, but now it is changed to tool steel. This tool steel is an alloy steel, which involves manganese, silicon, chromium, vanadium, tungsten, Can the purification of cobalt, molybdenum and other elements be achieved in this era?Zhu Cijiong really didn't know what to do.

However, this alloy technology has to be overcome, because the first two items are also related to the alloy. For example, the silicon steel sheet that must be used in the motor is an alloy. , tungsten and other elements of the alloy, can enhance the hardness and increase durability.

It seems that the success or failure of this precision machine tool, or what level of precision machine tool can be made, is ultimately determined by the alloy smelting. We must first find out what level the current Daming alloy smelting has reached, and whether there is the concept of element purification. , in order to start other research.

If one is an expert in this field, it must be Song Yingxing. Zhu Cijiong immediately ordered Song Yingxing to enter the palace to face the saint.

After Song Yingxing received the edict, he was quite surprised. It seemed that he had heard that since the queen was happy, the emperor was going crazy with joy. He didn't care about anything and just stayed with the queen wholeheartedly. Why did he suddenly recruit him now? Where is Miya Mika?

Of course, surprises are surprises, but it doesn't mean that he doesn't want to go. After receiving the order, he immediately dropped everything and hurried to the palace.

Song Yingxing is Zhu Cijiong's confidant, so the two of them naturally did not have the sense of alienation between the monarch and his subjects when they met, and after the ceremony, Song Yingxing even did not forget to congratulate: "Congratulations to the emperor, congratulations to the emperor, congratulations to the empress, the blessings of the world!" "

Zhu Cijiong smiled and nodded, motioning for him to sit down at the conference table together, and then said with emotion: "I was too happy for a while, and almost forgot about state affairs. Fortunately, the two queen mothers reminded me, and I just woke up. The country's affairs are the most important, and the country's affairs are the most important."

Song Yingxing retorted in a rare way: "Your Majesty, please forgive me for being daring. The Empress is happy, and that is a major matter for the country. It is normal for the Emperor to be so concerned."

Zhu Cijiong shook his head with a smile and said: "Okay, okay, let's not talk about this, I have come to ask you about something important this time."

Song Yingxing straightened his face immediately, cupped his hands and said, "Please ask your majesty to inquire."

Zhu Cijiong thought for a while, and asked hopefully: "Chang Geng, do you know that besides gold, silver, copper and iron, there are other things that are similar to gold?"

This question is almost out of Song Yingxing's job, and he said without thinking: "Back to the emperor, I know that the earth produces metal to make use of the world and future generations. There are five main types of metallic things, one is gold, and the other is silver. , the third is called copper, the fourth is called iron, the fifth is called tin, and it is supplemented by lead, Japanese lead, etc., and the types are too numerous to enumerate!"

Damn, he knew both tin and lead, and other metal elements, but Zhu Cijiong didn't know what this Japanese lead was. He asked curiously, "What is Japanese lead?"

Song Yingxing explained unsurprisingly: "There is no such thing as Japanese lead in ancient books, but it is a name and color established in modern times. It is normal that the emperor has never heard of it. This Japanese lead is mainly used to make brass. The copper used in this world There is only red copper that can be smelted after mining. However, if calamine or Japanese lead is added to smelt together, it will be transformed into brass; if arsenic and other drugs are added, it can be smelted into white copper; It can be smelted into bronze; tin can be added to make ring copper; and Japanese lead can be added to cast copper."

Now Zhu Cijiong understands. After a long time, Japanese characters are zinc. Why use Japanese characters? Could it be that this thing came from Japan?Impossible, Dongying is so far behind at the moment, how could it be more advanced than Daming in smelting technology, he asked curiously: "Why is this thing called Japanese lead? Could it be obtained from Japanese pirates?"

When Song Yingxing heard this, he showed a strange face, shook his head in embarrassment and said: "Uh, your majesty, this Japanese is not a Japanese Japanese pirate, but fierce. Since this thing is very similar to lead but more violent than lead, it is called Japanese lead."

Zhu Cijiong blushed tenderly. The Japanese character actually has other meanings. He is ignorant, but hearing Song Yingxing's tone, does this era already know how to refine zinc?He asked curiously again: "Then where did this Japanese lead come from?"

Song Yingxing explained in detail: "This Japanese lead is made of calamine. Put ten catties of calamine into a clay pot each time, coat the outside of the clay pot with mud to seal it, and then grind the surface. Smooth, let it dry gradually. Do not use fire to prevent the clay pot from cracking. Then use briquettes to pad the calamine pot layer by layer, and spread firewood underneath to make the fire red, and finally the clay pot The calamine stone can be melted into a ball. After the clay pot is cooled, the pot is smashed and taken out is Japanese lead."

Damn, the ancient version of the vacuum heating reduction method!
This city, it seems that metal smelting and metal purification has already established a certain foundation in this era, and it is not difficult to develop it.
