✦ Synopsis
This paper looked into hot metal corrosion behavior for graphite refractory used in blast furnace hearth, consisting of 50% graphite and 50% anthracite, impregnated with TiO 2 , ZrO 2 carrying solutions. The method used for corrosion was the Finger Test, which was conducted in an induction furnace with 30 Â 30 Â 280 mm bar-shaped test specimens, and the hot metal and slag used were taken from the CSN #2 Blast Furnace runner, the test temperature was 1470 8C with a sixty-minute isotherm. After the corrosion test, the specimens were characterized by their dimensional variation, X-ray diffractometry and Scanning Electronic Microscopy (SEM).
