SUMMARY:Development of standard argon rinsing practices for optimum steel cleanliness - "OptiClean"
DESCRIPTION:Steel cleanliness has become increasingly important throughout the years, bringing steelmaker’s attention to operational parameters that can optimize and fulfill these quality requirements. Argon stirring at the LMF is one of the key steps on achieving optimized steel cleanliness, especially if rinsing is performed before CaSi addition (pre-rinse). Trials were performed at Vallourec Star (Youngstown-Ohio) and heats were produced in 2 different scenarios: with and without pre-rinse. Lollipop samples analyzed on ASPEX demonstrates that pre-rinsed heats presented a strong drop on inclusion density (by -50%) when compared to heats that were not pre-rinsed (inclusion density stable). Pre-rinse practice was standardized at VStar.
