NON-COOKED CARBON-CONTAINING BRICK AND MASSES BASED ON SINTERED MAGNESIA

摘要

P THE INVENTION CONCERNS CARBON-CONTAINING BRICK-COOKED BRIEF AND MASSES, BASED ON SINTERED MAGNESIA, WHICH CONTAINS A CARBONACEOUS SUBSTANCE IN THE LIQUID AND SOLID STATE IN A QUANTITY WHICH GIVES IN THE PRODUCT, AFTER COKEFACTION, A RESIDUAL CARBON CONTENT OF 2 TO 30 BY WEIGHT. / P P THEY CONTAIN METAL CHROMIUM, OR A METAL COMPOUND OF CHROME, IN A QUANTITY OF 1 TO 20 BY WEIGHT, CALCULATED AS A METAL CHROME, ESSENTIALLY IN THE FORM FINE GRAINS HAVING A GRANULARITY FRACTION LESS THAN 1MM, REPRESENTING AT LEAST 80 BY WEIGHT, IN RELATION TO THE QUANTITY OF METAL, AND CONSIST OF SINTERED MAGNESIA FOR 60 TO 97 WEIGHT. / P P APPLICATION AS MATERIALS FOR THE FILLING OF OXYGEN INJECTION CONVERTERS, ELECTRIC ARC FURNACES ETC. / P
