STRUCTURAL TRANSFORMATIONS IN SLAGS THE CONTINUOUS CASTING OF STEEL WHEN HARDENING
Presents the results of investigation of structure and physico-chemical properties of slag from the tundish and the mould and slag-forming mixtures used for their guidance. It is established that slag melts have a biphasic structure of the emulsion. The dispersion medium of the emulsion is aluminosilicates of calcium and magnesium, similar in composition to the natural mineral of the melilite and the disperse phase consists of oxides and carbides of different metals. As the share of the dispersed phase is small (about 4 %), the properties of molten slag are determined by the properties of the dispersion medium. Two-phase structure of the liquid slag is the result of cocrystallization of structure formation upon cooling a liquid slag.
