Abstract:

Iron-sulphur alloys which contained up to 3.5 sulphur were desulphurized at 1545C by gas mixtures which contained 2-100 hydrogen along with argon andor helium as diluents. The rate of the reaction was measured by observing the rate of production of hydrogen sulphide. The results indicated that equilibrium between hydrogen, sulphur and hydrogen sulphide was established at the gas-metal interface and that the rate was controlled by diffusion of H2S away from the interface. The Reynolds number of the gas directed at the surface of the melt was important in determining the flux of H2S, and kinetic expressions were derived which were in good agreement with the main observations.
