“…The density of liquid Fe-Cr alloys was derived from the relation ρ(Mg/m 3 ) = 7.034 − 0.00567w Cr at T = 1823 K and the mass% of Cr, w Cr < 24, which was obtained by the sessile drop method. 22) The maximum measurement error was estimated to be ±1% for the surface tension and ±0.5% for contact angle.…”

The surface tension of liquid Fe-16 mass%Cr alloys and its wettability with alumina substrate at 1823 K were determined as a function of oxygen activity which was less than 0.0070 using the sessile drop technique. Oxygen was found to be strongly surface active in liquid Fe-16 mass%Cr alloys. The variation of surface tension of Fe-16 mass%Cr alloys with oxygen activity can be described by the following equation:

“…9) The density of liquid Fe-16 mass%Cr alloys was derived from the relation &(Mg/m 3 )=7.034-0.00567w Cr at T ¼ 1823 K and the mass% of Cr, w Cr < 24, which was obtained by the sessile drop method 10) without considering the effect of sulphur content. The densities of Fe-16 mass%Cr-S alloys at 1808, 1845 and 1883 K were the values measured using the sessile drop method in this study and calibrated by the value of 1823 K by Sharan et al…”

The surface tension and wettability of liquid Fe-16 mass%Cr-S alloy with alumina substrate at 1823 K and the temperature dependence of surface tension of liquid Fe-16 mass% Cr-S alloy in the temperature range of 1808-1883 K were measured using the sessile drop technique. The surface tension and contact angle of liquid Fe-16 mass%Cr-S alloys with alumina substrate decreased markedly with increasing sulphur concentration in the alloys. The variation of surface tension of liquid Fe-16 mass% Cr-S alloys with sulphur activity can be described by the following equation: ' 1g ¼ 1640 À 182 lnð1 þ 157a S Þ (mass% O=0.0037-0.0075, mass% S 0.195) (mN/m). The interfacial tension between liquid Fe-16 mass% Cr-S alloys and alumina substrate, calculated using Young's equation, can be expressed by the following equation: ' s1 ¼ 2170 À 220 lnð1 þ 237a S Þ (mass% O=0.0037-0.0075, mass% S 0.195) (mN/m). The work of adhesion between liquid Fe-16 mass% Cr-S alloys and alumina had a tendency to increase with increasing sulphur concentration. The temperature coefficient of surface tension, d'=dT, for Fe-16 mass% Cr-S system in the temperature range of 1808-1883 K increased with increasing sulphur concentration, and changed from negative to positive value when the sulphur concentration exceeded 20 mass ppm.

The solidification behavior of slags is a complex subject due to the varied chemical compositions of steelmaking slags. However, recent experimental developments, using the fact that slags that do not contain significant quantities of transition metal oxides are transparent, has allowed the development of optical techniques to observe slag solidification behavior. While "curiosity based research" was the initiator of such studies, it has quickly become apparent that observation of the phenomenon of slag solidification has lead to a much deeper understanding of the role of slag solidification behavior in the process of the continuous casting of steel. In this paper findings from observation of slag solidification will be discussed with reference to developments in continuous casting.
