EVALUATION METHOD OF ABRASION RESISTANCE, CORROSION RESISTANCE AND OXIDATION RESISTANCE OF CARBON-INCLUDING REFRACTORY

摘要

PROBLEM TO BE SOLVED: To provide an evaluation method of corrosion resistance capable of preventing oxidation of carbon during the heating or temperature-rising time of a carbon-including refractory.;SOLUTION: This evaluation method of abrasion resistance of the carbon- including refractory is characterized by heating the refractory 1 indirectly through a protection plate 2 placed on the carbon-including refractory, and, after continuing the heating until the protection plate 2 disappears or after removing the protection plate 2, blowing an abrasion medium into a burning flame, spraying the medium onto the protection plate 2 surface to thereby abrade the refractory, and measuring the remaining thickness and/or the attrition area of the refractory.;COPYRIGHT: (C)2002,JPO
