Contact Angle of Molten Steel Applied to the Development of Clog-resistant Submerged-entry Tundish Nozzles
The sessile drop method, modified by use of a doser tube rather than in situ drop formation, was used to study commercial steel compositions in contact with idealized refractory substrates. Steels containing varying amounts of carbon, aluminum, and titanium were tested in hydrogen and forming gas atmospheres at 1600EC. All of the compositions investigated had significantly different equilibrium contact angles than pure iron, but steel chemistry overall had a limited effect on wetting. A reaction of the high titanium steels with forming gas is still under investigation.
