Three-dimensional slab deformation of solidifying shell at central bearing during high speed continuous casting

摘要

This paper describes a local internal crack resulting from three-dimensional slab deformation of a solidifying shell at the central bearing during high-speed continuous casting. This internal crack is not explained by the present bulging model, as we constructed a new model in which three- dimensional slab deformations at the central bearing result from the coefficient of slab bulging and the coefficient of bulging strain using the finite-element method, and calculate a two-dimensional beam model taking into consideration the elastic, plastic and creep deformations.
