If the technological point of metal casting appears, it means that you have formally mastered higher-level forging methods, such as modular casting. Sophisticated and exquisite bronze ornaments can be cast, thus officially declaring the entry into the next era.
Of course, population and productivity are also necessary conditions for workshops and forging plants to operate normally.
Eureka ascended.
Yan Zai told Guang Chengzi that in his southern territory, there are many skilled craftsmen, including some legendary craftsmen, who can make many wonderful and delicate instruments.
Guang Chengzi frowned suddenly.
"Yijun and Danzhu? Yijun, I know, the earliest Qiaochui, a master craftsman praised by the world, I am a little interested in him, but not much. As for Danzhu, a carpenter, even Di Fang Xun's eldest son, what is that, a junior, can he stand alongside me!"
Guangcheng heard that Danzhu was a post-master master, Guangcheng said angrily: "A real man will never be in the same rank as Ah Hong!"
Guangchengzi looked down on Danzhu, thinking that Danzhu's craftsmanship was not worthy of being on par with him, and Guangchengzi felt that he had surpassed masonry and carpentry and reached the professional level of a metalsmith, how could he be compared with him, a small carpenter?
However, Yuzai gave a few examples, all of which were made with Danzhu's help. After hearing this, Guangchengzi frowned deeply, feeling a little suspicious.
But he quickly said: "What can be built with wood and stone, gold and copper can also be built"
"Boy, do you want me to go to your territory with you and help you work? Yes! As long as you take me as your teacher, everything is easy to talk about."
Guang Chengzi spoke suddenly, despising Yuzai.
You boy, old man, I have lived for more than a thousand years, what kind of messy intestines have I never seen?
? If you want the old man to help you with a free job, just tell me, but the price is not low.
"Do you think the old man is interested in the things you said? If you don't take the old man as your teacher, the old man will not go with you."
Guang Chengzi stared at Yan Zai. At this time, everyone had already started on the road again. Yan Zai laughed, and the atmosphere was a little awkward
The oldest method of melting and casting is often considered to be the lost wax method, but before the lost wax method, a longer and more efficient method appeared in the Shang Dynasty. This method is called the lost wax method. The technical principles of the Fa have evolved from it.
Lost incineration method, also known as lost foam casting or lost rope casting.
Using rope as a mold is an integral casting process, which is often used to cast bronze wares. Its main function is to make utensils without mold lines. After the fan is made, the incinerable model and the fan are fired together, and the model will be burned to ashes. After removing these ash, you can get an integral mold without a fan surface, which is called a fan. If this fan is used to make castings, there will be no fan lines
Xihuang, Xunwu Mountain, beyond the source of the Wei River.
This mountain has no grass and trees, but is rich in gold and jade. There are many wild beasts in the mountain. In the nearby mountains, Zhu Yan lives. This kind of strange beast looks like an ape, with a white head and red feet. Once it appears, a great war will break out in the world.
The people of Emperor Hong's clan arrived here temporarily to rest and wait.
Emperor Hong himself was in a copper smelting earth house.
Last time in Yanxi Mountain, Dihong found the mold left by Yanzai, so after careful study, he figured out something.
The metal is smelted into a liquid that meets certain requirements, then poured into the mold, cooled and solidified, and cleaned to obtain a casting with a predetermined shape, size and performance.
Eureka ascended.
The opening of many technology points is due to accident, including picking up leaks.
The crucible is smelting copper ore
loading¡¡
After several hours of burning, Master Dihong, who had been busy for half a day, melted the copper ore into copper water, and then poured the copper water into the prepared mold.
The data continues to be loaded
Finally, after a long time, in the midst of being busy, I seemed to see the appearance of some kind of treasure that I kept refreshing.
Seeing the copper ax melted in front of him, Dihong stretched out his hand, the craftsmen around were shocked and tried to stop him, but Dihong ignored them.
As Dihong's hand touched the copper ax, a cold breath gathered, and the red copper ax, which was originally in a high temperature state, instantly began to cool down.
In Dihong's palm, vitality surged, and his methods were against the sky. The craftsmen around him stood up straight, watching thisScene but dare not speak.
Emperor Hongshi touched the finished product, and there was still a big gap between this ax and what he expected, but at least this time it was a complete success.
And this ax, even if it can't be used as a sophisticated weapon, it is definitely very useful for doing farm work.
He is not a fire witch, so he can't rub molten iron with his hands like Yan Zai, but even if he is a fire witch, he rarely has the means of Yan Zai.
What Emperor Hongshi is learning and exploring now is the separate casting method and welding method in the fan casting technology.
This is an advanced technology of the block norm method. At this time, the Central Plains already had the block norm method.
The earthen kilns in the past were not enough to heat copper and other metals to a liquid state, but Emperor Hong fully restored the traces left by the concubine with his superb ancient wisdom.
So the present adobe workshop was born.
Use vitality and witchcraft to inject new earthen kilns to simulate a stressful environment; combine several earthen kilns to strengthen its airtightness and durability, and dig out special vents so that the pressure can be concentrated. More than a dozen people used sheepskin bags to blow wind and ensure firepower.
There is also a saying about the choice of copper. To make weapons, bronze and brass should be selected. Red copper is soft in texture and has a high melting point, so it is not suitable for pouring weapons.
Emperor Hongshi knew that the so-called copper-tin combination can better melt and cast copper. This kind of knowledge existed in the era before Chi You, and as the ancestor of soldiers, Chi You left too many foundations for people of this era to smelt. technology.
For example, "Three days to learn the casting of bronze wares", "Three years of masonry and five years of coppersmithing", "Fire explanation", "Blast furnace manufacturing", "Ore science popularization", "How bronze is made"
There was a gleam in Dihong's eyes.
Just like the experience bar is constantly rising, technology is constantly being damaged and explored.
If he can master this technology, he can quickly surpass the Central Plains in terms of population and productivity!
"The people of the Chikata clan"
Dihong narrowed his eyes and thought a lot.
"Even a sorcerer from the Chifang clan who escaped can easily build crude copper smelting ware. Although he is a fire witch, it also shows from the side that all kinds of crafts are prosperous in the southern land."
Emperor Hong was tempted, and regretted it a little bit. He knew that he had moved to the south, but now there is no way to turn back, and it is cheaper for Jinyun.
"Wait, Zhongyuan, I will be back soon, with bronze utensils all over the mountains and plains!"
"I don't know if Taotie has captured the land in the south at this time?"
The time came not so long ago.
In the south, on the edge of the great river.
Taotie had already held a big axe, led a group of people, and drove a group of small boats, relying on the herbal medicine that gave off a bad smell made by Luwangdu, and sneaked across the East Beach.
Everything is going according to plan.
"Southerners never imagined that we would suddenly appear behind them."
The leaders smiled strangely, and soon they couldn't laugh anymore.
They saw a notice board with a sheep's head painted on it in front of them, and the behavior of that sheep was particularly embarrassing.
Taotie was suspicious.
Could it be a fraud?
Did the southerners see through their tricks?
So he pointed to Huozheng of his tribe and asked him to take a look. Huozheng was terrified immediately, and quickly said that there are so many leaders, why do you think highly of me?
Taotie said, you are Huozheng, and you must take the lead by taking the lead. I will marry your wife, so you go.
Huozheng left with hatred, and when he got to the signboard, he saw the situation clearly, but let out a sigh of relief.
Seeing that Huo was letting everyone pass, Taotie nodded. After everyone passed, Huo Zheng pointed to the sign and said:
"This sign has been standing here for some time, and it has been rotted a lot by the wind and rain. It seems to be at least 20 to 30 years old."
Twenty to thirty days, that is, half a month and a month?
Taotie pondered for a while.
The sign so long ago must not be that they knew about their plan. After all, it is impossible for the opposite side to predict the future, and it says
"The great lamb warns you that construction is ahead, garbage is being cleaned up, and traffic is prohibited If you don't listen to dissuasion, you will be at your own risk?"
