Abstract Based on the thermal–mechanical coupling finite element model described in Part I of present work, the thermal behavior of one high strength ship plate steel solidifying in slab continuous casting mold was simulated with the practical continuous casting conditions of a steel plant, and the availability of the model was verified by in–plant measurement temperature. With this model, the thickness distributions and thermal behavior of air gap, mold flux (including liquid flux and solidified flux), and the variation characteristics of heat flux and surface temperature, as well as the influence of casting speed, mold taper, and mold flux properties on thermal behavior of the steel solidifying in mold were investigated.

Key words: slab continuous casting mold thermal behavior air gap
