摘要
With an increasing demand for high grade electric magnetic steels, SSRF(Single Snorkel Refining Furance) has got much attention due to its high efficiency of both decarburization and desulphurization. However the desulphurization mechanism of this kind SSRF is remarkably different from that of other steel refining processes such as LF,RH etc. , so it is necessary to understand the behaviour of desulphurization clearly. A mathmatical model has been established in this paper to investigate the degree of desulpurization with time on the basis of the influencing factors such as sulphur capacity of flux,stirring energy of molten steel. It is shown that the desulpurization rate constant is about 1.0E-8 in accordance with the data from the practical test of a steel plant with SSRF.
