This paper investigates longitudinal depressions and cracks in steel continuous-cast in funnel moulds using a finite-element model to simulate thermo-mechanical behavior of the solidifying shell in the thin-slab caster mould at the Corus Direct Sheet Plant in IJmuiden, The Netherlands. The commercial code ABAQUS is utilized to explore the impact of the funnel shape on stress distribution within a two-dimensional section of the shell during its movement through the mould. The model first simulates heat transfer, guided by heat flux profiles derived from extensive plant measurements and embedded thermocouples, and accounts for local gap formation that reduces heat flux. Subsequently, this temperature data is integrated into a mechanical model incorporating grade-dependent elastic-viscoplastic behavior, ferrostatic pressure, taper adjustments, mould-wall oscillations, and interactions with the proiled mould wall. Validation of the results is achieved through comparison with plant measurements, including instances of breakouts and crack statistics. The model's application reveals the implications of enhancing casting speed and funnel design to mitigate longitudinal cracks.
