Abstract

"Slag attack is a major mechanism of failure for certain carbon bonded refractories. Static as well as dynamic tests have been conducted to investigate the corrosion process.

A static finger test was utilized to test specimens in order to understand the reactions which take place and to determine the phases present after corrosion. This test was also used to determine the corrosiveness of the slag so that adjustments to its composition could be made in order to facilitate a dynamic test. The dynamic finger test was chosen because it better simulates the actual service conditions these bricks experience inside the BOF.

Several techniques were used to analyze the specimen after they were exposed to the slag including: x-ray, cathodoluminescence (CL), reflective light microscope (RL), and the SEM/EDS. Four distinctly different morphologies of spinel were observed in all of the test specimens and each are described in detail. The accurrence of the spinel had a precise zoning pattern which is also discussed in detail"--Abstract, page 1.
