Abstract

This study reveals the quantitative analysis on the infiltration of molten slag into pores in bricks with the slagging reactions. The experiment was carried out with an FeO-SiO2 slag on practically used Al2O3-SiO2 bricks at 1 523 and 1 573 K, then semi-theoretical formulations were introduced for the interpretation in a connected pores system. A satisfactory explanation was presented to the experimental observations on the slagging infiltration of the molten slag in the industrial bricks through the characterization of the pores system and the correlative evaluations of immersion force, slagging reactivity and wetting behavior. The unified interpretaion then suggests the possibility for the anticipative estimation of the phenomenon out of the material natures concerned.
