Aeroengine Casting Process and Spring and Autumn Chu State
Aeroengine Casting Process and the "Lost Wax Method" of Chunqiu Chu State"
1978 to 1979, a number of noble tombs of Chu in the mid-Spring and Autumn Period were discovered in Xiasi Temple, Xichuan, Henan.
A total of unearthed there are more than 700 bronzes. These bronzes use a variety of casting methods that combine muddy casting, split casting, and muddy casting and split casting. One of the copper bans and two copper lamps are cast by the famous "lost wax method.
This method is also used for modern casting of high-precision artifacts such as aeroengines, missiles, and instruments.
Therefore, the "lost wax method" found in the tomb of Xiasi Chu in Xichuan is the first physical proof of this method in China and the world.
"Lost wax method" is the use of wax texture soft, soluble, plastic characteristics. First, the soluble wax material is made into a utensil model. Because the wax is soft, it can also be finely carved. Then the model is coated with liquid mold mud for the copper caster to harden it into a shell.
Repeated many times, you get a thicker shell. Then heat to see the wax melt out, and you get one."Fan".
In this way, the surface of the cast utensils is smooth and the size is accurate.
The State of Chu in the Spring and Autumn Period, because of its unique conditions, its bronze and iron smelting and casting are quite developed. Even mining in some local mines began during the Shang and Zhou weeks.
