    摘要: An alumina-chrome refractory composition comprises 30-60% by weight of alumina-silica type material containing 50-95% by weight of alumina with the major part in coarse particle size, and 70-40% by weight of chrome type material with the major part in fine particle size. In a modification, the alumina-chrome refractory composition comprises 70-99% by weight of a mix consisting of the alumina-silica type material and chrome type material in the above percentages, and 1-30% by weight of at least one of the materials selected from the group consisting of alumina, zircon, zirconia, magnesia, spinel, clay, silicon carbide and titanium oxide in fine particle size ranges.
