A thermomechanical modelling of continuo

The development of high tensile strength steels for automotive applications necessitates advancements in continuous casting technology to enhance both internal soundness and surface quality of the slabs. This study's objective was to optimize the process parameters according to the specific characteristics of various continuous casting machines. A macroscopic thermomechanical model was developed to simulate the behavior of steel slabs during casting, thereby assessing the effects of operational variables on the mechanical properties of the slabs. The methodology involved performing a series of simulations to investigate the impact of casting speed, cooling strategies, and other relevant conditions on the resultant slab quality. Results indicated significant correlations between the bulging effects during casting and the resulting internal and surface defects, including macrosegregation and cracking. Optimized parameters were identified for enhancing casting conditions, ensuring that the slabs maintain their integrity even under high tensile conditions. These findings contribute valuable insights for steel manufacturers looking to revamp older casting equipment and refine their operational techniques, ultimately leading to improvements in product quality and performance. The implementation of this model presents a practical approach for adapting to the continuously evolving demands in steel production.
