Research on Genetic Characteristics of Slab Bulge in Continuous Casting Process

Abstract:

Bulge deformation is an important factor that causes inner crack and declines the quality for slab. This has a significant genetic phenomenon in continuous casting process. In order to explain this feature, a two-dimensional FEM model for slab that includes viscoelastic and dynamic characteristic has been built. Positive creep and reverse creep were introduced to explain this mechanism. Roll pitch, shell characteristic, slab withdrawing speed and other process parameters that influence bulge’s genetic level are discussed. A nonlinear equation was suggested to describe the relationships between these factors and genetic level of bulge.
