Abstract

fetched live from OpenAlex

Con la creciente demanda de aceros cada vez más bajos en fósforo (P), junto con el constante aumento en el contenido de este elemento en el mineral utilizado para producir arrabio, es necesario un proceso en constante evolución para la eliminación de fósforo del acero en los convertidores BOF. Este artículo tiene como objetivo mostrar el desarrollo para reducir el nivel de fósforo en el acero desoxidado con aluminio y silicio producido en los convertidores de Arcelor Mittal Tubarão (AMT), empresa ubicada en el municipio de Serra, Brasil. Este complejo produce 5 millones de toneladas pero tiene una capacidad instalada de 7,5 millones. El análisis de las variables del proceso tales como adición de fundentes, temperatura y el patrón de soplado, se basó en los modelos clásicos de la partición de fósforo. Los resultados presentados comparan los valores de fósforo obtenidos en el acero líquido antes y después de los cambios realizados, y analiza el desgaste de refractarios en los convertidores.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
