Abstract

A process for the manufacture of refractory bricks, especially uncalcined, of magnesite-chromium and chromium-magnesite using a sintered material (simultaneous sintering) which is obtained without fusion by joint calcination of materials containing chromium oxide, especially chromite, with magnesia, optionally sintered magnesia or other natural or synthetic magnesium compounds that provide magnesium oxide when calcined, at temperatures of at least 1,700º C, preferably above 1,750º C, and in which the periclase and chromite particles are directly bonded between each other, characterized in that the sintered material in granulated form is mixed with 3 to 9%, preferably 4.5 to 5.5%, of tar and/or fish, especially hard fish or bitumen, or possibly similar mixtures of high hydrocarbons. molecular weight, and is configured in bricks.
