Nowadays, people pay more and more attention to casting technology, especially factories and other enterprises, which are inseparable from such machinery, because casting machinery can not only obtain certain benefits in effective investment, but also be more convenient and efficient. While enjoying such convenient machinery, do you know the development process of casting technology? Then let Xiaobian lead you into the development history of casting technology in China.
The 875kg simu Wufang Ding of the Shang Dynasty, the honoring plate of Marquis Yi of the Warring States period and the transparent mirror of the Western Han Dynasty are all representative products of ancient casting. Most of the early castings were tools or appliances for agricultural production, religion and life, with strong artistic color. At that time, the casting process was developed in parallel with the pottery process, which was greatly influenced by the pottery.
When China developed to the Warring States period, the casting technology entered a new period. At that time, after the Shang Dynasty, we already had the simu Wufang Ding weighing 875kg. It can be seen how powerful the development of China's casting technology was. However, at that time, most of the objects cast in China were still agricultural production, religious or living tools, At that time, not only the casting process developed rapidly, but also the development of scouring tools was popular, and the casting process at that time was greatly affected by scouring tools.
In the 20th century, casting has developed rapidly. One of its important factors is the progress of product technology, which requires castings to have better mechanical and physical properties and still have good machinability; Another reason is that the development of machinery industry itself and other industries such as chemical industry and instrument has created favorable material conditions for the foundry industry. For example, the development of testing means ensures the improvement and stability of casting quality, and provides conditions for the development of casting theory; The invention of electron microscope helps people go deep into the micro world of metal, explore the mystery of metal crystallization, study the theory of metal solidification, and guide casting production.
