HEATING AND MELTING OF WUSTITE PELLETS IN LIQUID SLAG

The melting behaviour of the metallized, porous wustite pellets immers ed in liquid slag, as well as the influences of the metallization rati o, pre-heating temperature of the pellet and slag temperature were exa mined in this work by means of an X-ray imaging system. The internal s tructure of the pellets after having been immersed in slag was checked by optical microscope and EPMA. The adoption of digital image process ing improved the image analysis dramatically and, as a result, some im portant phenomena, such as solid slag shell forming and melting, slag penetration, wustite component dissolution as well as the influence of experimental conditions, were quantified.
