Abstract

Assessing and quantifying the impact of various factors on nitrogen content in metal is vital for optimizing technological and operational strategies to minimize or prevent nitridation in the final steel product. Recognizing how individual factors affect nitrogen levels is crucial for predicting nitrogen quantities during both production and processing stages within a closed production cycle. This study investigates the factors influencing nitrogen content in crude steel before tapping, using Cohen's distribution table and graphical analysis. Although the impact of after-blows on nitrogen content is well established, the paper also explores other factors contributing to nitridation before tapping from the basic oxygen furnace.
