Continuous casting large round billet is a kind of continuous casting steel and iron making technology which is mainly used to produce seamless steel pipe billet. It is mainly used for the production of different caliber seamless steel pipe, round billet through the pipe requires no surface, internal cracks, and to prevent large particle inclusion caused by the inner surface defects of the steel pipe.
The manufacturing process of continuous casting large round billet mainly includes the following steps:
1. ** Molten steel solidification forming ** : molten steel continuously flows into tundish, mixed by tundish and then injected into crystallizer to cool and solidify, to obtain an infinite length of casting billet.
2. ** Cutting ** : The cast blank after cutting can be directly used for steel rolling production.
3. ** Continuous casting process ** : Continuous casting is the intermediate link between steelmaking and steel rolling, an indispensable part of the metallurgical process, but also an important part of the steel mill.
Continuous casting large round billet has the advantages of high precision, good quality, low energy consumption and high comprehensive metal recovery.
