Abstract
The corrosion resistance of resin bonded alumina/magnesia/graphite refracto ries containing different kinds of aggregates were investigated when submit ted to the action of slags of several CaO/SiO2 ratios. The laboratory testi ng was performed by means of the rotary slag attack test. Specifically eval uated was the influence of alumina/carbon ratio and magnesia and silica con tents on the refractories corrosion resistance. It was found that this prop erty could be improved by increasing the refractory Al2O3/SiO2 ratio as wel l as by choosing the appropriate Al2O3/C ratio. (C) 2000 Elsevier Science L td.
