Abstract

Reactions of Na//2CO//3 or Na//2SO//4 with iron, carbon and phosphorus were studied in the temperature range between 1 200 and 1 400 degree C by the use of iron, graphite and magnesia crucibles. The reaction between Na//2SO//4 and iron was more active than that between Na//2CO//3 and iron, but the reaction between Na//2CO//3 and carbon was violent compared with that between Na//2SO//4 and carbon. Dephosphorization and desulfurization of carbon-saturated iron (0. 2%P, 0. 05%S) were also investigated at 1 250 degree C by Na//2CO//3-Na//2SO//4 flux. The degree of dephosphorization and desulfurization and the evaporation loss of sodium and sulfur were obtained as a function of the flux composition.
