This paper investigates corrosion behavior in graphite refractory hot metal impregnated with ZrO2 and CeO2 carrying solutions used in Blast Furnace hearth, consisting of 50% graphite and 50% anthracite. Corrosions tests were carried out by means of finger test method in an induction furnace, using bar-shaped 30×30×280mm test specimens and hot metal from CSN #2 Blast Furnace runner. The temperature chosen for this test was 1520°C and 60-min isotherm. Upon test completion, test specimens were characterized by their dimensional variation, X-ray diffractometry and Scanning Electronic Microscopy (SEM).
