Özet

In this study, wettability between sprayable tundish lining (MgO) and molten steel was investigated by using sessile drop method. Content of glass fiber (SiO2) in the MgO varied between 0 to 8 wt% whereas mean particle sizes of the MgO were 25, 75, 150 and 300 mu m. Experimental results revealed that contact angle (0) of sessile drop on the MgO was not altered by the addition of glass fiber up to 1wt.% whereas above 2 wt.% addition decreased the 0 considerably. Contact angle, theta, increased considerably with increasing MgO particle size. SEM analysis showed deposition of glass phase was present at the interface as the finer MgO particles were used.
