Abstract

A process for the manufacture of refractory and calcined magnesite-chromium bricks and chromium-magnesite bricks using a sintered material (simultaneous sintering), which is obtained without melting by joint calcination of materials containing chromium oxide, especially chromite, with magnesite, optionally sintered magnesia, or other natural or synthetic magnesium compounds that provide magnesium oxide when calcined, at temperatures of at least 1700º C and preferably above 1750º C, and in which the periclase and chromite particles are directly bonded to each other , characterized in that the sintered material is granulated and configured in bricks and these bricks are calcined at temperatures of approximately 1500º C to 1600º C and then, optionally using vacuum, are impregnated with tar, fish, bitumen or possibly similar mixtures of high molecular weight.
