text: A process for the manufacture of unburned refractory magnesia-chrome and chrome-magnesia bricks which comprises shaping a mixture of chrome ore having a particle size distributed in the range from 0 to at most 6 mm., and natural magnesite having an MgO content of no more than 92% and a particle size from 0 to at most 0.2 mm., sintering the shapes without fusion at a temperature of at least 1750 C., granulating the resulting sintered material in which substantially all of the periclase particles are directly bonded with the chromium oxide particles, and shaping the granulated material alone with a binder into bricks and drying said bricks, said sintered material containing 5 to 40% Cr O having a lime:silica ratio of no more than 0.6 and a silica content of no more than 5.5
text: A process for the manufacture of burned refractory magnesia-chrome and chrome-magnesia bricks which comprises shaping a mixture of chrome ore, having a particle size distributed in the range of from to 6 mm., at least 65% of which has a particle size greater than 0.12 mm., and natural magnesite having an MgO content of no more than 92% and a particle size of 0 mm. to less than 0.12 mm., sintering said shapes at a temperature of at least 1700 C. without melting, granulating the resulting sintered material in which substantially all of the periclase particles are directly bonded with the chromium oxide particles, shaping the granulated material alone into bricks and burning said bricks at temperatures of about 1500 to about 1600 C.; said sintered material containing 5 to 40% Cr O no more than 5.5% silica and having a lime:silica ratio of no more than 0.6, and of said granulated material shaped into bricks from 60 to 80% thereof having a particle size greater than 0.12 mm.
