摘要 The wettability of the molten steel/Na 2O Li 2O SiO 2 B 2O 3 slag system was studied by a sessile drop method. It was found that the variation of the interfacial tension with the temperature in the molten steel/slag system is pretty little in the temperature range of 1 803-1 873 K. The interfacial tension remarkably decreases with increasing the oxygen content and/or sulfur content in molten steel. The contact angle for the molten steel/slag system is 153°-173°.
