Abstract
Based on theory of solubility of nitrogen in steel and de-nitriding kinetics
the control model of nitrogen alloying during AOD refining has been established. The application results for refining stainless steel 0Crl9Ni9N (≤0. 08C
18 ~20Cr
8 ~ 11Ni
0. 10 ~0. 16N) by a 45 t AOD unit showed that it was available to accurately control N content in stainless steel by solubility of nitrogen and de-nitriding in AOD process and the data calculated by model nicely conformed to real measured data in production.
