Abstract
Chrome-magnesite bricks used in the burning zone of an oil fired kiln were
examined during a shutdown period to study the mechanism of wear where stagging
action is ruled out. The hot end of the bricks were decomposed resulting in
formation of a powdery zone in kiln. Detailed study indicated vaporization of
magnesio-chromite from the hot face of the brick and deposition of the same in
comparatively cooler portions of the kiln. The left over bricks did not undergo
any appreciable chemical alteration.
