Continuous casting is an advanced method of casting in which molten metal is continuously poured into a special metal mold called a mold. The solidified (encased) casting is continuously pulled out from the other end of the mold.The development of continuous casting is an important means to optimize the structure of China's metallurgical industry, which will fundamentally change the low efficiency and high consumption of China's metal material production, and promote the development of product structure to the direction of specialization.The development of advanced continuous casting technologies, such as near-final continuous casting, single crystal continuous casting, high-efficiency continuous casting and hot charging of continuous casting billet, will be very active, and will promote the development of a series of new materials.
Centrifugal casting is a technique and method of pouring liquid
metal into a rapidly rotating mold to fill the mold and form a
casting.Because of the centrifugal motion, the liquid metal can
fill the mold well in the radial direction and form the free
surface of the casting.Cylindrical inner hole can be obtained
without core.Helps to remove gases and inclusions from liquid
metals.Affect the crystallization process of metal, thus improving
the mechanical and physical properties of castings.
