The phase and chemical transformations in slag-forming mixtures used in continuous casting and the ladle treatment of steel over a broad temperature range are studied. By physicochemical analysis, data are obtained regarding the relations between the endo- and exothermal effects and the time for silicate and slagmelt formation. The thermal diffusivity is determined by an improved method in which heat sources and sinks in the heated material are taken into account. On the basis of these results and preliminary values of the specific heat and density, the temperature dependence of the thermal conductivity is found for the slag mixtures. The results permit prediction of the economic consequences (including the thermal costs) of using slag mixtures, in selecting the initial materials for granule production and in casting the steel.
