摘要:
High purity fused grain and refractory compositions that contain a high purity fused grain made up of 35 to 85 wt. % chromia, 5 to 55 wt. % alumina, and 5 to 45 wt. % magnesia. Burned refractory brick having such a chemistry was found to unexpectedly possess superior resistance to AOD and electric furnace slags.
摘要:
A burned chrome-containing refractory and method which provides a refractory having less than 5 ppm total soluble chromium. Such product is obtained by adding to the starting mix less than 10 wt. % (often less than 3 wt. %) zirconia, silica, zircon, or molybdic oxide either individually or in combination.
