Abstract

This paper describes a kinetic analysis of the process of chromium evaporation from ferrous alloys smelted under reduced pressure. The study discussed comprised determination of the liquid phase mass transfer coeffi cient as well as the value of the constant evaporation rate. By applying these values as well as the values of the overall mass transfer coeffi cient estimated based on the relevant experimental data, the fractions of resistance of the individual process stages were established.
