Toroso decided to ask the explosion factory for some insights. Although they were not familiar with each other, in order to make a more fire-resistant stove, cooperation and discussion as well as a large number of prostitutes were necessary.
Since the emergence of black gunpowder and yellow gunpowder, people in Hongzhou have realized that different material elements can be decomposed and combined into new things.
Therefore, the number of employees in explosion factories is also increasing. Although some women do not want their men to work in such dangerous places, most of them have the heart to be bombers.
Moreover, the explosive factory now has excellent welfare benefits, with special approval from the superiors, so it can take advantage of public property.
Toroso set a small goal for himself, to produce a limited edition refractory brick with a fire resistance exceeding 1,500 degrees. In fact, it is difficult to exceed this temperature. In ancient times, with limited conditions and scarce means of obtaining materials, it was more than 1,000 degrees.
The raw materials for making such bricks are 500-degree refractory bricks, which are really not something you can pick up just walking around.
And this is actually related to the fuel, that is, the burning substance of the flame. No matter how the inferior burning substance is burned, the temperature cannot reach the standard. Therefore, the ancients distinguished between "gentle fire" and "forced fire". These are different fuels, cow dung
The fire made from fuel such as horse dung and chaff is a slow fire, while a strong fire is made from charcoal and coal.
Among them, the charcoal materials are generally oak and riverwood.
Oak is relatively hard, has strong burning power, and can be harvested locally in many places. Simply put, it is "cheap, easy to use, and durable", while oak is also a relatively special kind of wood.
Of course, when the temperature is not enough, some ancient people will perform some magical operations, such as "sacrifice the furnace with one's body"!
It seems that there is some scientific reason in it, but this is not important.
When Toocao left, Guangchengzi and Dui were still looking at the tap hole.
The flames are burning and the heat waves are rolling.
The color of the flame at the taphole has changed from red to white.
Gradually, it started to shine and turn white.
The temperature gradually rises.
A satisfied smile appeared on Guangchengzi's face.
But there was something abnormal about that batch.
Red, dark.
That's because the temperature is not up to standard, or it could be something else, but in short it's not a good sign.
Dui was a little anxious. Seeing Guangchengzi's beaming expression, he was so angry that he started tumbling over the keyboard.
"Come on, blow the wind!"
"Come on, add more ore!"
"Come on, add charcoal!"
Dui started throwing materials inside, which looked violent but was actually busy and not chaotic.
Gradually, those dark red colors began to turn brighter, and he felt relieved at the sight of his boss.
For truly qualified steel, the premise for using the steel pouring method is to have high-quality wrought iron that has been fired, and then the liquid pig iron is poured on the wrought iron, and after several degrees of smelting, the iron is carburized into steel. Because it is made
Pig iron and wrought iron "sink" together, so the steel produced is called "sink iron".
"Iron... coil the wrought iron bars in a curved manner, embed the pig iron pieces between the coiled wrought iron bars, seal the furnace with mud and smelt them, and then forge them after they are smelted to temper them together.
…”
"Without a good furnace, there will be no good iron. Without good iron, using low-quality wrought iron for steel filling will produce defective products that are worse than nothing."
Dui's voice rang out, and it seemed a pity that the iron he was responsible for just now had some problems because the furnace was not powerful enough. Of course, his own method was also wrong, but fortunately he corrected it in time.
Niao Cao paused and remembered these words in his heart.
After all, it is difficult for a clever woman to make a meal without rice.
This is definitely a big event that will go down in history, Niao Cao thought, but the more he thought about it, the more excited he became.
In this era, ordinary tribes did not even have access to copper. Their smelting technology was primitive, and the earthen furnaces were not resistant to fire. Almost every furnace used copper and earth.
Those who can smelt copper on a large scale are already powerful in the tribe, but the earth furnaces they need are not even as good as the defective ones in Hongzhou.
This kind of stove has become the most common and cheapest stove. In other tribes, it costs ten thousand gold to buy one, but in Hongzhou it only costs two yuan.
Nori Cao thought that now, everyone in future generations would know that the most important bricks in construction and production were made by himself.
This can already make you a wise man.
Although the bricks made by ourselves are not all of the same quality, if there are five or six wrong bricks in a furnace, the furnace is almost useless.
However, this is still because I am not very skilled in technology. After all, Brick only appeared not long ago.
When Toori was leaving, he heard people talking and conversing outside the large ironworks. Their tone was full of emotion, but he couldn't hear clearly.
The two people over there looked at some conditions outside the ironworks and said as they walked:
"In the past, things like iron were brought from the sky. The stones that flew down are now called meteors and meteors. They are considered by the world to be treasures given by heaven. The tribes who get the meteors can cast them to belong to the king.
tools, so they can dominate the weak and weak around them."
"But now, the things carried by those nightfalls are no longer enough to be called surprising by the world. In these tall furnaces, in the surging flames, and under the hammers dropped by those strong craftsmen, the things are calcined.
, what is hammered out is exactly what is needed most in a new era.”
"Things that were regarded as miracles in the old era have become ordinary in the new era. Maybe it will be like this in the future eras. So how can it be seen that God would give any divine objects? It turns out that everything in the world already exists, whether it is smelted or not.
, whether it’s casting or chemistry, it seems that they just discover these things that already exist, then give them names, and finally make use of them.”
Niao Cao didn't hear it very clearly. He just felt that it was two outsiders who were commenting on this place. At this time, it was more important to go to the explosion factory.
Yuzai came out to see him off, and Niao Cao left.
And the two people also walked a little further.
But their conversation was not gossip and truth that ordinary people could say. Due to the problems of the times, those women were not the only ones in this era who had long hair and short knowledge.
Regardless of whether it is a matriarchal society or a patriarchal society, those who have extraordinary vision and summed up knowledge, and make good use of this kind of thinking, are definitely extraordinary people in any era.
Before they left, they saw Yu Zai. The younger one laughed twice. When Yu Zai entered, he asked the older one next to him:
"That's Bai Kui? He doesn't look very old, he's about the same age as me."
"Yes, but he is so young and is already a teacher of the princes. You have many talents, but you can only teach some simple ideas. If you want to change the world, you have to be someone like him!"
The older man said again: "Let's go and find a place to live first. I heard that if you apply for work registration here, you can get an assigned residence..."
Of the two, the older one is called Empress Ji, and the younger one is called Mo Ru.
In the legend, Empress Ji was one of Shun's teachers, while Mo Ru taught Yu the Great.
