Abstract:The SELF-SReM model belongs to the high order sub-regular melt model. It systemized the components activities for multi-component metal liquid and the whole homogeneous in metallurgical slag, and provides a reliable activity databank of components for thermodynamic prediction of engineering. The characteristic, structure, simple form, fitting method of parameters, matching relationship of parameters at different levels and probability to forecast phase diagram in this model are presented systematically.
Key words: sub-regular solution model; component activity of melt; prediction of phase diagram
