Absorption of Nitrogen by Melts of the Fe–C System During Metal Blowing with Oxygen

Аннотация

Kinetics of nitrogen absorption and desorption by melts of the Fe–C system with surface and volumetric oxidation in a stream of oxygen containing 0.2% of nitrogen with an initial metal temperature of 1350–1600°С, [С] = 0.8–3.8%, oxygen flow 0.24–1.8 liter/(minŊkg), are studied. It is established that there is excess chemical potential of nitrogen in a boundary layer compared with the nitrogen content in a gas stream.
