The mystery of the mysterious rust of the 72-ton Zhenhe Iron Ox underwater
Introduction:
Since ancient times, people have always been full of curiosity and desire to explore mysterious historical sites. In ancient China's water conservancy projects, there was an amazing phenomenon -- the 72-ton Zhenhe iron ox located under the water, after more than 1,200 years of baptism, there was not a trace of rust! This phenomenon is still incomprehensible to this day. This article will provide a detailed scientific solution to this puzzle from a professional point of view.
Historical background of the Iron Bull
The iron ox is an important component in ancient Chinese water conservancy projects, mainly used to fix river embankments and stabilize water potential. According to archaeologists, the use of iron oxen can be traced back to the Tang Dynasty, when it was mainly used to prevent the Yellow River from bursting and protect farmland and villages. With the passage of time, the production process and materials of the iron ox continued to improve, and gradually became an important part of ancient Chinese water conservancy projects.
The process of making the iron bull
The ancient iron ox production process is very exquisite, first of all, it is necessary to select high-quality iron ore, which has been smelted and refined many times to make pure pig iron. Then, the pig iron is cast into various shapes, such as cow shapes, pictograms, etc., and finally quenched and tempered to make the iron ox have enough strength and toughness. In the production process, a variety of anti-corrosion measures will also be adopted, such as grease and tin plating, etc., to prolong the service life of the iron cattle.
Iron bull's anti-corrosion technology
Although the ancient iron ox production process has been very advanced, long-term underwater immersion can still cause serious corrosion to the iron ox. What is the reason why this 72-ton Zhenhe iron ox has been able to remain intact for more than 1,200 years?
1. Special material selection
According to archaeologists, the iron ore used in this Zhenhe iron cow is a high-grade magnetite, which contains a high iron content and a low impurity content, so it has good corrosion resistance.
2. Advanced manufacturing technology
When the ancient blacksmiths made the iron ox, they used a unique quenching technology to form a hard oxide film on the surface of the iron ox, which effectively prevented moisture and oxygen from coming into contact with the metal inside the iron ox, thereby slowing down the rate of corrosion.
3. Strict anti-corrosion measures
On the surface of the iron ox, the ancient blacksmith also applied a thin layer of grease, which can not only prevent moisture and oxygen from coming into contact with the metal on the surface of the iron ox, but also play a lubricating role and reduce the damage of friction to the iron ox. In addition, the surface of the iron cow is also plated with a layer of tin, this metal has strong oxidation resistance, which can further delay the corrosion process of the iron cow.
The current state and value of the Iron Bull
Today, the 72-ton Zhenhe Iron Ox has become an important archaeological site, attracting the attention of countless tourists and archaeologists. Through the study of this iron bull, we can understand the development level and technical level of water conservancy engineering in ancient China, which has important reference value for the study of ancient Chinese civilization.
At the same time, this iron bull also provides us with valuable inspiration: in the future construction of water conservancy projects, we should continue to carry forward the spirit of ancient craftsmen, adopt more advanced technology and materials, and create a better living environment for human beings.
Conclusion:
The reason why there is no rust at all for more than 1,200 years is not only related to the special material selection, advanced production technology and strict anti-corrosion measures, but also inseparable from the wisdom and skills of ancient craftsmen. The unveiling of this puzzle not only gives us a deeper understanding of ancient water conservancy projects, but also provides valuable reference for today's water conservancy project construction.
