摘要：

Factors which influence the nitrogen content in steel are analyzed. A multiple regression analysis on 4000 heats showed the different variables having an influence on the nitrogen content of the teeming bay sample, which is higher when the purity of blowing oxygen is low, when the nitrogen content of hot metal is high, and when the quality of scrap is poor. Guidelines for obtaining steel grades with very low nitrogen levels are given.
