My Great Qin Cannot Die

Chapter 314: Iron metallurgy technology

The emperor, the lord of all peoples!

Only when there are ten thousand people can there be an emperor who is above ten thousand people. As an emperor, only by benefiting all the people can he gain the support of all the people.

As for the appearance of sugar, in addition to Ying Zheng's desire to support the Daqin Royal Chamber of Commerce, the most important purpose is to benefit the people. Potatoes and sweet potatoes are too far away, so he can only start step by step.

He wanted to change the eating habits of the people of the Great Qin Empire. Ying Zheng knew that at this time, his approach to meat was too unexpected and completely different from later generations.

The way of eating meat in this era is too primitive. One of them is that there is basically no change in "burning". From the composition of the word, it can be understood that the meat is roasted on the fire.

Although there is "frying", it has the same name and actual difference. It is to pour meat sauce on the rice and add ointment (animal oil) to heat it; "boiled" is also different from the stewed meat of later generations. Pieces of meat and even whole pigs and sheep are boiled in plain water.

The utensils used are the tripod and the wok that appear frequently. The tripod is generally round, with three legs below, which can be ignited and heated under the tripod; the wok has no legs, but has two ears like handles that can be hung up and burned in the air.

As for the other methods, they are all made with raw meat. It is often referred to as "脍" together with "Zhi", that is, the raw meat is cut into slices and eaten with seasoning. Fish soup is the predecessor of Japanese sashimi.

Therefore, the literal meaning of the popularity can be understood as the finely chopped barbecue that everyone loves to eat.

There are also several ways to remove the blood vessels and tendons of the raw meat, chop or smash it, and then add various seasonings to marinate or mix it with food: "Zi" means to marinate and soak the meat in wine; "Boil" " is to make meat into floss;

"醢" (hǎi) is made into meat sauce; "preserved" is to cut raw meat into strips, marinate and air-dry, also called "xiu".

……

This kind of situation must be changed. After all, it is also known as a foodie empire in later generations. Of course, the reason why Ying Zheng cares is that raw meat is unsanitary.

Moreover, most of the meals of the Great Qin Empire did not have much flavor, and even in this era, only the royal family would grind the grain.

The rest were eaten by steaming the grains after they were hulled. Ying Zheng had carefully sorted out Li Kang's memories, so he hated these things.

It's just that the most important thing in the Qin Empire has never been to eat, but to survive, so this problem had to be left to this day.

Therefore, iron tools must come out!

Only with the advent of iron tools can all this be changed, and the advent of iron tools, coal mining, the outbreak of war, and the introduction of rice, corn, potatoes, etc. in Champaign, can completely change the Qin Empire.

Therefore, the most important and urgent task is the development of iron smelting technology.

At this moment, Ying Zheng's thoughts flickered in his heart. After a while, he couldn't help but set his eyes on the huge map of the Qin Empire in the study. He knew in his heart that outside Longxi County, there was the West Sea, and there were a lot of salt lakes near the West Sea.

To the north of the West Sea, on the site of Da Yuezhi, there is a huge iron ore vein, and in Pingcheng, Yanmen County, there is a huge coal mine vein.

And all of these are divine objects that changed the Qin Empire.

With all kinds of thoughts going on in his mind, Ying Zheng looked at Gong Zuoqiu at this moment, and said in a low voice, "Husband Lost, how is the iron smelting technology in Daqin Shang's workshop?"

"Is it possible to make iron tools that surpass bronze tools?"

Ying Zheng knew in his heart that the Qin Empire had to transition from the Bronze Age to the Iron Age. Whether mining coal or mining iron ore veins, iron tools were needed.

At this time, he could only ask Gongxuqiu.

Hearing this, Gong Shuqiu was silent for a while, then turned towards Ying Zheng and said, "Your Majesty, the bronze smelting technique in the Central Plains during the Shang and Zhou dynasties has reached a considerable level, but from the mid-Shang Dynasty to the weekend for hundreds of years, artificial iron smelting has not Developed under the influence of superb copper smelting technology, meteorite iron was still used when artificially smelted iron was occasionally seen during the Western Weekend.”

"Because there has been no large-scale iron ore mining in Daqin, and also due to the immaturity of iron smelting technology, I have been using bronze weapons."

"During the process of merging the six countries, Shang Gongfang absorbed some of the artisans from the palaces of the six countries, and only then did it further develop the iron smelting technology."

Speaking of which, Gong Shuqiu had a deep gaze, bowed solemnly towards Ying Zheng, and said, "Your Majesty, after many tests in the Shang Workshop, the weapons made of pig iron have both high hardness and toughness, and are rich in raw materials and low in price. "

"Nowadays, Shang Gongfang has mastered that pig iron is hard and wear-resistant, but pig iron is brittle and not resistant to bumps."

"In order for pig iron tools to overcome these weaknesses of pig iron, Shang Workshop optimized the invention of cast iron annealing technology."

"The annealing technology reduces the brittleness of pig iron and improves its toughness. It is used as a raw material for weapon casting, so that the resulting weapon has a sharp edge."

"At the same time, it integrates the cast iron decarburization steel technology, which maintains the advantages of less pig iron inclusions, uniform structure and pure texture, which can be used for the casting of weapons."

……

Hearing Gong Shuqiu finish speaking, Ying Zheng nodded. At this moment, he also understood that ~www.wuxiaspot.com~ Daqin Shang Workshop only integrated the development of iron smelting technology on the land of the Central Plains over the years.

It didn't go any further!

Ying Zheng knew in his heart that the defects of pig iron were too great, and the weapons of the three armies of the Qin Dynasty, as well as the farm implements of the people all over the world, had to be stronger.

What's more, he knows that there are many coal mines in Pingcheng, so that he can have enough high temperature to forge iron mines.

Thinking of this, if Ying Zheng Development mines the coal mines in Pingcheng, it can completely promote the method of frying steel in this era.

Ying Zheng had a certain impression in his mind about the method of frying steel, so he organized a speech in his heart, and said, "Husband loses, if you heat the pig iron to a molten or basically molten state, and fry it in the molten pool, With the help of oxygen in the air, the carbon contained in the pig iron is oxidized to become steel or wrought iron."

"In this way, the utilization of iron ore veins will inevitably be improved. If fried steel and fried steel-type wrought iron become the most important materials for making iron tools, especially weapons and production tools. This will be a great help to the Qin Empire. "

Speaking of which, Ying Zheng paused for a moment, he knew in his heart that what he said was too advanced, Gong Zuoqiu might not understand, he was silent for a while, and said.

"Wait until the pig iron is processed into wrought iron, or just, then heat and forge the raw material, squeeze out impurities, improve the structure, carburize to increase the stiffness, and then make utensils; mainly by repeated heating, folding and forging to improve the final product. the quality of the product.”
