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

摘要

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 degrees C, [C] = 0.8-3.8%, oxygen flow 0.24-1.8 liter/(min?kg), 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.
