Recycling Spent Chrome Refractories from Steelmaking Furnaces

摘要

In Bureau of Mines research on recycling chrome refractory wastes, used refractories from argon-oxygen decarburization and electric steelmaking furnaces were beneficiated, concentrates were reformed into briquets, and modulus of rupture tests were conducted at 1,350C. The test results indicated that the beneficiated minus 6-mesh material could be used for producing magnesia-chrome refractories.
