Improvements in Process Practices With a Focus on Reduction of Slivers in Ultralow-Carbon Automotive Exposed Application Grades at Ternium Brasil

The demand for high-quality clean steel requires the reduction of non-metallic inclusions; this is particularly significant in the manufacturing of ultralow-carbon steels for automotive exposed applications. During the galvanization process, there is an increase in the probability of inclusions being revealed. Inclusions can originate from various sources such as deoxidation and reoxidation, entrapment of slag, wear of refractory materials, and undesired chemical reaction. Considering all these issues, adjustments were implemented in the production parameters, starting from initial stages of steel production in the converter until continuous casting. The aim is to mitigate the formation and entrapment of non-metallic inclusions.
