Description

Billet continuous casting is a fully mature technology. Among existing billet casting machines, curved-type machines dominate. In particular, with the exception of a very small number of extra-large billet casting machines, nearly all newly built billet casting machines are curved.

The primary difference among curved-type billet casting machines lies in the type of dummy bar. Currently, both flexible and rigid dummy bars coexist, each with its own advantages and disadvantages. Using rigid dummy bars in small-section continuous casting machines further simplifies the structure of the secondary cooling chamber support section, facilitating accident handling in the event of a breakout.
