Abstract
Over the past years, ArcelorMittal Tubarão has undertaken a progressive renovation project of its steel plant facilities, focusing on the three continuous casters; One of the key interventions was made on the online mould width change system through the adoption of the Q-WIDTH model supplied by Danieli. The upgrade process began in 2012 on Continuous Casting Machine Nº 1, implementing the Q-WIDTH package. This was followed by Continuous Casting Machine Nº 2, during the revamp in 2019, with the installation of new caster equipment and the enhanced Q-WIDTH algorithm. The results achieved with the new release of Danieli Q-Width have been the ground for proceeding with Continuous Casting Machine Nº 3 in 2022, involving modifications to existing equipment and the introduction of the latest algorithm. The primary goal of these revamps was to eliminate the breakout occurrences associated with the original algorithm for online mould width adjustment. Over time, additional benefits were obtained including enhanced of operational safety (eliminating breakout occurrence during mould width change), increased flexibility in the production process, increased reliability of the system and equipment associated to mould width change, better planning, greater productivity, increased slab conditioning yield and improved slab quality. This paper details the previous and current conditions of the related equipment, reviews the improved width change procedure, and presents the results achieved.
