Mold for continuous casting of metal comprises a narrowing section which extends from the melt surface level to a desired depth and corresponds to the magnitude of shrinkage due to a phase transformation

摘要

The vertical section of the mold cavity (2) at the inner mold wall surface has a narrowing section (6) which extends from the level of the melt surface (3) to a desired depth, and corresponds to the magnitude of shrinkage caused by transformation of the cast metal from liquid to solid phase.
