Assessment of the quality of fused chromium- containing refractories from foreign manufacturers

Quality assessment of foreign-made fused-cast chrome-corundum, chrome-alumina-zirconia, and high-chrome refractories intended for lining melting units in metallurgy and glassmaking has been conducted. It is shown that their most important characteristic is high corrosion resistance when exposed to highly aggressive melts. Data on the use of fused-cast chrome-containing refractories Monofrax K-3, ER 2161, and Monofrax E in the production of mineral fibers, flat and colored glass, as well as in radioactive waste disposal facilitiesare presented.
