Abstract:
By analysing and disposing the experimental data from Shanghai NO. 5 I&S Works, comparing these data with the results undertaken by some investigators, the equilibrium conditions of [C]-[O], [Cr]-[O], [C]-[Cr] during stainless steel making in STB combined-blown converter are approached. The results show that the [C]-[Cr] equilibrium relation is different from Hilty's equation which is suitable for the stainless steel making in electrical furnace. Therefore, it is not very accurate to measure the [C]-[Cr] equilibrium conditions in STB combined-blown converter.
