Abstract

For the quantitative analysis on the infiltration of molten slag into pores in refractories, the wettability of an FeO-SiO2 slag was studied for Al2O3-SiO2 bricks and dense refractory plates by the sessile drop method in consideration of surface roughness on the samples. The results have been phenomenologically discussed together with those previously obtained in refractory capillarles. The conclusions are;<BR>(1) The contact angle is dependent on the ratio of the slag drop height to the width. As this ratio became smaller, the contact angle observed approached the value calculated on the presumption of the slag drop shape being a part of a sphere.<BR>(2) The time-dependency of the contact angles is intermediate on the refractory bricks between the typlcal ones on both the dense alumina and mullite refractories. The behavlor is correlative to the quantitative fractions of the minerals which the bricks are composed of.
